Description
System och forfarande far mojliggorande av autonom drift och/eller extern styrning av ett motorfordon TEKNIKENS OMRADE FOreliggande uppfinning avser ett system for mOjliggorande av autonom drift och/eller extern styrning av ett motorfordon, ett forfarande for mOjliggorande av autonom drift och/eller extern styrning av ett motorfordon samt ett motorfordon innefattande ett sadant system. FIELD OF THE INVENTION The present invention relates to a system for enabling autonomous operation and / or external control of a motor vehicle, a method for enabling autonomous operation and / or external control of a motor vehicle. a motor vehicle and a motor vehicle comprising such a system.
UPPFINNINGENS BAKGRUND OCH KAND TEKNIK Att framfOra ett motorfordon staller hoga krav pa operatOren dã det finns manga komplexa forutsagbara och oforutsagbara situationer att ta hansyn till. BACKGROUND OF THE INVENTION AND PRIOR ART Driving a motor vehicle places high demands on the operator as there are many complex predictable and unpredictable situations to consider.
Det finns idag hjalpmedel for att underlatta operatorens arbete, sasom adaptiv farthallare, nOdbroms, kOrfaltsvarnare och liknande. Dessa hjalpmedel kraver dock att det finns en operatOr i motorfordonet som sjalv kan bedoma situationen och vidta lampliga atgarder. Today, there are aids to facilitate the operator's work, such as adaptive cruise control, emergency brake, anti-roll bar and the like. However, these aids require that there is an operator in the motor vehicle who can assess the situation himself and take appropriate action.
OperatOren utgor en star del av driftskostnaden fOr ett motorfordon, aven i de korfall dâ belastningen pa operatOren är valdigt lag. Detta är exempelvis fallet i gruvapplikationer dar korningarna ofta bestar av att lasta pa vid en punkt, for att darefter kOra till en andra punkt och lasta ay. Ett annat exempel är vid transport av resendrer mellan ett flygplan och en flygplatsterminal. I dessa ap- plikationer är trafikfOrhallandena kontrollerade och det fOrekommer inte nagra fotgangare, cyklister eller liknande stOrningar. Gruvor exempelvis, är dessutom ofta lokaliserade pa sa satt att det kravs transport och infrastruktur for personalen. Detta genererar stora kostnader. For att minimera kostnaderna är det darfor Onskvart att i vissa typer av drift helt automatisera motorfordonens framfo- rande. 1 Far att, pa ett sdkert salt, framfara ett motorfordon autonomt, det viii saga utan att en operator/fOrare styr motorfordonet pa plats i fordonet, kravs en god uppfattning om motorfordonets omgivning. Detta kan astadkommas genom anvandning av sensorer med hog precision och avancerad informationsbearbet- fling samt kommunikation mellan motorfordonets olika styrenheter. Att utveckla och implementera en sadan losning for autonom drift eller fjarrstyrning av ett motorfordon är tidskrdvande och kostsamt. The operator constitutes a large part of the operating cost for a motor vehicle, even in cases where the load on the operator is very low. This is the case, for example, in mining applications where the grains often consist of loading at one point, and then driving to a second point and loading ay. Another example is when transporting passengers between an aircraft and an airport terminal. In these applications, traffic conditions are controlled and there are no pedestrians, cyclists or similar disturbances. Mines, for example, are also often located in such a way that transport and infrastructure are required for staff. This generates large costs. In order to minimize costs, it is therefore advisable to completely automate the driving of motor vehicles in certain types of operation. 1 In order to drive a motor vehicle autonomously on a safe salt, that is to say without an operator / driver steering the motor vehicle in place in the vehicle, a good idea of the motor vehicle's surroundings is required. This can be achieved by using sensors with high precision and advanced information processing as well as communication between the motor vehicle's various control units. Developing and implementing such a solution for autonomous operation or remote control of a motor vehicle is time consuming and costly.
Olika farfaranden och system har fareslagits i den kanda tekniken far att astadkomma autonom drift. Till exempel visas i dokument US 2012/0239238 Al hur en industriell truck styrs autonomt langs med en definierad bana genom anvdndning av ett styr- och navigationssystem. Styr- och navigationssystemet skapar och skickar ett kommando gallande hastighet via ett kommunikationsndtverk till en processormodul. Processormodulen skickar vidare kommandot till truckens styrenhet, vilken i sin tur styr drivsystemet utifran ndmnda kom- mando. Banan kan definieras genom en kabel under golvet, tejp eller andra ref erenser pa golvet, vilka styr- och navigationssystemet kanner ay. Denna lasning astadkommer forvisso autonom drift av trucken men krdver en pa for-hand definierad bana langs med vilken trucken ska framforas samt ett internt styr- och navigeringssystem. Various procedures and systems have been compromised in the prior art to achieve autonomous operation. For example, document US 2012/0239238 A1 shows how an industrial truck is steered autonomously along a defined path by using a steering and navigation system. The control and navigation system creates and sends a command gallant speed via a communication network to a processor module. The processor module further sends the command to the truck's control unit, which in turn controls the drive system based on the above command. The path can be defined by a cable under the floor, tape or other references on the floor, which the control and navigation system can ay. This loading certainly ensures autonomous operation of the truck but requires a pre-defined path along which the truck is to be driven and an internal steering and navigation system.
Trots kdnda lasningar pa omradet finns det fortfarande ett behov av att vidareutveckla ett kostnadseffektivt system och farfarande far autonom drift av ett motorfordon. Hari anges kostnadseffektivt i termer av utvecklingskostnader och driftkostnader. Despite well-known readings in the field, there is still a need to further develop a cost-effective system and still have autonomous operation of a motor vehicle. Hari is stated cost-effectively in terms of development costs and operating costs.

Darmed astadkommes en tidseffektiv och kostnadseffektiv lOsning fOr mOjliggOrande av autonom drift och/eller extern styrning av ett motorfordon. Genom att den, av det externa styrsystemet, genererade signalen fOrst mottages hos datagranssnittet begransas det externa styrsystemets atkomst av det fordonsinterna styrsystemet. Detta är sdrskilt fordelaktigt dd. det fordonsinterna styrsystemet kan innefatta information och funktioner som fordonstillverkaren ej vill att externa anvandare ska ha tillgang till. Samtidigt kan abstraktionsnivan ho- jas gentemot det externa styrsystemet for att forenkla anvandandet. Pa samma salt medfor systemet enligt fOreliggande uppf inning att det externa styrsystemet inte kan ta Over motorfordonets styrning utan att dess signaler fOrst har 6 passerat datagranssnittet. Datagranssnittet medfor aven att paverkan pa motorfordonet minimeras i de fall som inkoppling av det externa styrsystemet sker pa ett felaktigt salt. The in-vehicle steering system is preferably part of the motor vehicle in its basic design. When the motor vehicle is driven manned by an operator / driver, the motor vehicle is controlled via the in-vehicle control system. By arranging a data interface of the motor vehicle, which data interface is in communicative connection with the external control system and the internal vehicle control system, two-way communication between the external control system and the internal vehicle control system is possible. The interface is thus configured for communication between the vehicle internal control system and the external control system. The interface can form part of the in-vehicle control system. In this way, it is possible to use an external control system already existing on the market for autonomous operation and / or external steering, connected to the motor vehicle. The motor vehicle thus does not need to be provided with costly systems and tools for achieving autonomous operation and / or external control during manufacture, but the buyer of the motor vehicle can at a later time connect an existing external control system for autonomous operation and / or external control to the unit configured. the data interface and the in-vehicle control system. This provides a time-efficient and cost-effective solution for enabling autonomous operation and / or external control of a motor vehicle. Because the signal generated by the external control system is first received at the data interface, the access of the external control system is limited by the vehicle internal control system. This is particularly advantageous dd. the in-vehicle control system may include information and functions that the vehicle manufacturer does not want external users to have access to. At the same time, the level of abstraction can be increased compared to the external control system to simplify use. On the same salt, the system according to the present invention means that the external control system cannot take over the control of the motor vehicle without its signals having first passed the data interface. The data interface also means that the impact on the motor vehicle is minimized in cases where connection of the external control system takes place on an incorrect salt.
Motorfordonet kan saledes styras antingen manuellt av en operator hos motor- fordonet eller autonomt eller externt genom det externa styrsystemet. The motor vehicle can thus be controlled either manually by an operator of the motor vehicle or autonomously or externally through the external control system.
Fordonet kan drivas autonomt i ett farsta lage och drivas operatOrsstyrt (manuellt eller externt) i ett andra lage. En operator, exempelvis en farare, kan sá- ledes anvanda samma datagranssnitt som vid autonom drift nar operatoren onskar styra fordonet externt. Namnda operator kan saledes styra fordonet externt medelst ett manoverorgan, dar operatoren star placerad externt/vid sidan av fordonet, exempelvis i en korg eller en s.k. sky-lift eller manuellt via reglage anordnade i en hytt hos fordonet. The vehicle can be operated autonomously in a first mode and operated operator-controlled (manually or externally) in a second mode. An operator, for example a driver, can thus use the same data interface as in autonomous operation when the operator wishes to control the vehicle externally. Said operator can thus control the vehicle externally by means of an actuator, where the operator is placed externally / next to the vehicle, for example in a basket or a so-called sky-lift or manually via controls arranged in a cab of the vehicle.
Det externa styrsystemet definieras som ett styrsystem som tillhandahalls och installeras av en part annan an fordonstillverkaren. Det externa styrsystemet kan innefatta enheter som är anordnade hos motorfordonet och/eller enheter som inte är anordnade hos motorfordonet. Det externa styrsystemet innefattar larnpligen hardvara i form av sensorer, navigeringssystem, kameror och lik- nande f6r positionsbestamning av motorfordonet och fOr att fortlOpande detektera exempelvis objekt, hinder, personer och djur, fOr att erhalla en god omvarldsuppfattning. Larnpligen innefattar det externa styrsystemet aven atminstone en styrenhet, som mottager instruktioner gallande den anskade driften av motorfordonet. The external control system is defined as a control system provided and installed by a party other than the vehicle manufacturer. The external control system may comprise units which are arranged in the motor vehicle and / or units which are not arranged in the motor vehicle. The external control system basically includes hardware in the form of sensors, navigation systems, cameras and the like for position determination of the motor vehicle and for continuously detecting objects, obstacles, people and animals, for example, in order to obtain a good perception of the surrounding world. The external control system also comprises at least one control unit, which receives instructions for the required operation of the motor vehicle.
Vid autonom drift av motorfordonet erhaller styrenheten hos det externa styrsystemet instruktioner pa en hag niva, exempelvis kor Iran en position A till en position B. Namnda styrenhet kan vidare vara anordnad i kommunikativ for- bindelse med externa enheter sasom en elektronisk kartdatabas eller andra liknande system, som kan bidra med information som kan paverka den autonoma driften av narnnda motorfordon. Namnda styrenhet bearbetar signaler 7 fran ovan namnda hardvara och/eller de externa enheterna tillsammans med instruktionerna och fordonsparametrar, for att faststalla en lamplig rutt fOr motorfordonet. Fordonsparametrarna kan utgoras av fordonsvikt, fordonshOjd, accelerationsformaga etc. Namnda styren het faststaller vidare lampliga styr- parametrar for autonom styrning av motorfordonet enligt den bestamda rutten. During autonomous operation of the motor vehicle, the control unit of the external control system receives instructions at a high level, for example Iran runs a position A to a position B. The said control unit can furthermore be arranged in communicative connection with external units such as an electronic map database or other similar systems. , which can provide information that may affect the autonomous operation of the said motor vehicle. Said control unit processes signals 7 from the above-mentioned hardware and / or the external units together with the instructions and vehicle parameters, in order to determine a suitable route for the motor vehicle. The vehicle parameters can consist of vehicle weight, vehicle height, acceleration design, etc. The said steering wheel further determines suitable steering parameters for autonomous steering of the motor vehicle according to the determined route.
Styrparametrarna innefattar instruktioner pa en lag nivã och kan avse styrvinkel, lampligt vaxelsteg hos en transmission, bromsverkan, acceleration hos motorfordonet, vinkelhastighet och/eller vridmoment hos ratten och liknande detaljerade styrparamentrar. Den av det externa styrsystemet genererade sig- nalen innefattar atminstone en sadan lagnivastyrparameter. The steering parameters include instructions at a low level and may refer to steering angle, light gear ratio of a transmission, braking action, acceleration of the motor vehicle, angular speed and / or torque of the steering wheel and similar detailed steering parameters. The signal generated by the external control system comprises at least one such low level control parameter.
Vid extern styrning av motorfordonet faststaller styrenheten hos det externa styrsystemet styrparametrar baserat pa en fran en operator Onskad framforing av motorfordonet. Med extern styrning kan avses fjarrstyrning av ett motorfor- don medelst fjarrstyrningsorgan sâ som en barbar dator, en fjarrkontroll, joys- tick eller liknande organ hanterade av en operator. Det externa styrsystemet kan exempelvis innefatta en dator arrangerad hos fordonet och granssnittet kan utgoras av en signalledning, varvid en operator medelst en knapptryckning exempelvis kan onska att accelerera, decelerera, vaxla och/eller svanga mo- torfordonet. Styrparametrarna hos signalen fran det externa styrsystemet inne- fattar precis som vid autonom drift av motorfordonet instruktioner pa en lag niva och kan avse styrvinkel, lamplig vaxel, bromsverkan, acceleration och liknande detaljerade styrparametrar. During external control of the motor vehicle, the control unit of the external control system determines control parameters based on one from an operator. External control can refer to remote control of a motor vehicle by means of remote control means such as a barbarian computer, a remote control, joystick or similar means handled by an operator. The external control system may, for example, comprise a computer arranged at the vehicle and the interface may consist of a signal line, whereby an operator by means of a push of a button may, for example, wish to accelerate, decelerate, shift and / or swing the motor vehicle. The control parameters of the signal from the external control system, as in the case of autonomous operation of the motor vehicle, include instructions at a low level and can refer to steering angle, lamp gear, braking action, acceleration and similar detailed control parameters.
En styrparameter kan aven benamnas begaran. Saledes till handahaller det externa styrsystemet en begaran gallande exempelvis en hastighet, med vilken motorfordonet bar framforas. Begaran frail det externa styrsystemet Over-fors via datagranssnittet till det fordonsinterna styrsystemet, som bearbetar begaran och avgiir om begaran ska exekveras. Enligt en utforingsform innefat- tar signalen fran det externa styrsystemet en begaran, som utgors av en posi- tiv eller negativ hastighets- och/eller bromsbegaran samt en Onskad styrvinkel. Alternativt innefattar signalen f ran det externa styrsystemet en begaran, som 8 utgors av en accelerations- och/eller decelerationsbegaran samt en onskad styrvinkel. Alternativt innefattar signalen fran det externa styrsystemet en begaran, som utgors av en vinkelhastighet och/eller rattmoment. A control parameter can also be called a request. Thus, the external control system provides a request for, for example, a speed at which the motor vehicle could be driven. The request is sent to the external control system Over-fors via the data interface to the in-vehicle control system, which processes the request and decides whether the request is to be executed. According to one embodiment, the signal from the external control system comprises a request, which consists of a positive or negative speed and / or brake request and an undesired control angle. Alternatively, the signal from the external control system comprises a request, which consists of an acceleration and / or deceleration request and a desired control angle. Alternatively, the signal from the external control system comprises a request, which consists of an angular velocity and / or steering torque.

Namnda styrenhet overfor saledes signaler innefat- tande styrparametrar till manovreringssystemen som clamed styr motorfordonet. Manovreringssystemen utgors lampligen av ett bromsstyrningssystem for styrning av exempelvis fardbroms, hjalpbroms och parkeringsbroms, drivorgan och/eller styrorgan. Med hjalpbroms kan avses retarder, avgasbroms, elektrisk hjalpbroms eller liknande. Manovreringssystemen utgors vidare lampligen av ett motorstyrningssystem fOr styrning av motorfordonets motor och framdrivning samt ett vaxlingsstyrningssystem for styrning av vaxling hos motorfordonet. Manovreringssystemen utgors saledes av system, som via det fordonsinterna styrsystemets styrenhet paverkar bland annat motorfordonets hastighet och riktning. Preferably, the in-vehicle control system comprises a plurality of operating systems arranged in communicative connection with the control unit of the in-vehicle control system. Said control unit thus receives signals including control parameters for the maneuvering systems that clamed the motor vehicle. The maneuvering systems suitably consist of a brake control system for controlling, for example, cruise control, auxiliary brake and parking brake, drive means and / or control means. Auxiliary brake can refer to retarder, exhaust brake, electric auxiliary brake or the like. The maneuvering systems furthermore suitably consist of a motor control system for controlling the motor vehicle's engine and propulsion and a shift control system for controlling the shifting of the motor vehicle. The maneuvering systems thus consist of systems which, via the control unit of the in-vehicle control system, influence, among other things, the speed and direction of the motor vehicle.

Enligt en utfOringsform av fOreliggande uppf inning tillhandahalles ett system, varvid namnda styrenhet är anordnad att kontrollera atminstone en fordons- funktion hos namnda motorfordon. According to an embodiment of the present invention, a system is provided, wherein said control unit is arranged to check at least one vehicle function of said motor vehicle.
Namnda styrenhet kan genom att med signaler kommunicera med fordonets manovreringssystem och/eller andra fordonsinterna styrenheter fa information om funktion hos fordonet, det viii saga information om huruvida alit fungerar som det ska hos fordonet. Den atminstone ena fordonsfunktionen kan vara att en specifik sensor/givare fungerar som den ska, exempelvis en momentindikator, en varvtalsgivare eller liknande. Den atminstone ena fordonsfunktionen 10 kan aven vara att en specifik aktuator som exekverar begdran fran det externa styrsystemet fungerar som den ska. Exempel pa fordonsfunktion att kontrollera kan vara att bromsarna inte är overhettade, att vdxelladan fungerar som den ska, att motorn inte har momentneddragningar, att ddcken inte har punktering och/eller att det finns tillrackligt med luft i bromssystemet.

By checking at least one vehicle function of said motor vehicle, it can be determined before the vehicle has been put into autonomous operation or controlled externally whether the motor vehicle is suitable to be driven autonomously and / or externally. On this salt, a secure system is achieved for autonomous operation and / or external control, where both the vehicle and its surroundings are protected from driving immature vehicles autonomously and / or externally.
Enligt en utfOringsform av foreliggande uppf inning tillhandahalles ett system, varvid ndmnda styrenhet has det fordonsinterna styrsystemet är anordnad att tillata initiering av autonom drift och/eller externt styrning av ndmnda motorfor- don dä namnda fordonsfunktion uppvisar fullgod funktion.

Genom att styrenheten hos det fordonsinterna styrsystemet validerar den in- kommande signalen fran det externa styrsystemet astadkommes en kontroll fore namnda signal overfors till manovreringssystemen och darmed styr motorfordonet. Pa sã satt sakerstalls att inga orimliga eller skadliga signaler, eller signaler som styrenheten inte kan tolka, styr motorfordonet. Detta är sarskilt viktigt da signalen fran det externa styrsystemet innefattar styrparametrar pa lag niva. Valideringen innefattar fOretradesvis kontroll av pa forhand bestamda kriterier gallande det externa styrsystemets signalers format. Exempelvis innefattar valideringen kontroll av den av det externa styrsystemet genererade signalens frekvens, det vill saga hur ofta signaler fran det externa styrsystemet sands. Exempelvis, i det fall signaler är avsedda att sandas var fyrtionde milli- sekund men ett avbrott uppstar, stoppar styrenheten den autonoma driften. Vidare kan vid valideringen kontrolleras en av det externa styrsystemet genererad kontrollsumma. Valideringen innebar att formatet med vilket kommunikation sker via datagranssnittet maste ske enligt tydligt definierade kriterier for att mottagas av det fordonsinterna styrsystemet. Pa sã salt sakerstalls att for- donstillverkaren har kontroll Over hur fordonet styrs och darmed framfOrs aven nar ett externt styrsystem anvands fOr autonom drift och/eller extern styrning. Vidare sakerstalls att det externa styrsystemet är ett godkant och tillatet styrsystem fOr autonom drift och/eller extern styrning av fordonet. By the control unit of the in-vehicle control system validating the incoming signal from the external control system, a control is achieved before the said signal is transferred to the maneuvering systems and thereby controls the motor vehicle. This means that no unreasonable or harmful signals, or signals that the control unit cannot interpret, control the motor vehicle. This is especially important as the signal from the external control system includes control parameters at the team level. The validation includes preferably checking of predetermined criteria depending on the format of the external control system signals. For example, the validation includes checking the frequency of the signal generated by the external control system, i.e. how often signals from the external control system are transmitted. For example, in the event that signals are intended to be sent every forty milliseconds but an interruption occurs, the control unit stops the autonomous operation. Furthermore, during the validation, a checksum generated by the external control system can be checked. The validation meant that the format with which communication takes place via the data interface must take place according to clearly defined criteria in order to be received by the in-vehicle control system. In such a case, it is ensured that the vehicle manufacturer has control over how the vehicle is steered and thus even when an external steering system is used for autonomous operation and / or external steering. Furthermore, it is ensured that the external control system is a good edge and permitted control system for autonomous operation and / or external control of the vehicle.
Enligt en utfOringsform innefattar valideringen kontroll av atminstone ett pa for-hand bestamt kriterium avseende rimligheten i begaran fran det externa styrsystemet. Genom att rimligheten hos namnda signal kontrolleras kan begaran som kan skada fordonet undvikas. Ett sadant exempel pa en begaran som skulle kunna skada fordonet kan vara en begaran om att lagga i backvaxeln da fordonet framfors i en viss hastighet. 12 Dá valideringen visar att signalen fran det externa styrsystemet inte uppfyller det atminstone ena pa fOrhand bestamda kriteriet, eller anses vara skadlig for fordonet stoppar styrenheten lampligen signalen fran det externa styrsystemet och den autonoma driften och/eller externa styrningen avbryts. Foretradesvis genererar aven styrenheten en signal fOr intern styrning och overfOr signalen for intern styrning till manavreringssystemen. Harvid uppnas ett robust och sakert system. According to one embodiment, the validation comprises checking at least one predetermined criterion regarding the reasonableness of the request from the external control system. By checking the reasonableness of said signal, the request that can damage the vehicle can be avoided. Such an example of a request that could damage the vehicle could be a request to put in the reverse gear when the vehicle is being driven at a certain speed. 12 When the validation shows that the signal from the external control system does not meet at least one predetermined criterion, or is considered harmful to the vehicle, the control unit aptly stops the signal from the external control system and the autonomous operation and / or external control is interrupted. Preferably, the control unit also generates a signal for internal control and transmits the signal for internal control to the operating systems. A robust and secure system is achieved.
Enligt en utfOringsform av fOreliggande uppf inning tillhandahalles ett system, varvid namnda styrenhet är anordnad att faststalla framforingskaraktaristika och/eller en omgivningskonfiguration, dar namnda styrenhet är anordnad att anpassa namnda validering pa basis av namnda faststallda framforingskaraktaristika och/eller namnda faststallda omgivningskonfiguration. According to an embodiment of the present invention, there is provided a system, wherein said control unit is arranged to determine performance characteristics and / or an environment configuration, wherein said control unit is arranged to adapt said validation on the basis of said established performance characteristics and / or said fixed figures.
Genom att bestamma framforingskaraktaristika och/eller omgivningskonfigura- tion och basera namnda validering pa basis av dessa parametrar kan lampligheten has de externa styrsignalerna som styr den autonoma driften och/eller den externa styrningen avgOras fran fall till fall. Framforingskaraktaristika kan enligt ett exempel vara fordonets framfOringshastighet. Omgivningskonfigura- tion kan vara en elektronisk representation av en omgivning av namnda motor- fordon. Namnda omgivningskonfiguration kan inbegripa lutningen hos underlaget, strukturer, objekt, personer, djur etc. By determining performance characteristics and / or environmental configuration and basing said validation on the basis of these parameters, the suitability can have the external control signals that control the autonomous operation and / or the external control is determined from case to case. According to one example, the driving characteristics can be the vehicle's feed speed. Ambient configuration can be an electronic representation of an environment of said motor vehicle. Said environmental configuration may include the slope of the substrate, structures, objects, persons, animals, etc.
Enligt ett exempel kan det vid vissa tillfällen, sasom t ex vid start i backe, vara rimligt att en begaran om broms samtidigt som en begaran om gas begat's. According to an example, on certain occasions, such as when starting on a hill, it may be reasonable for a request for a brake to be made at the same time as a request for gas.
Samma begaran, dvs. en begaran om broms samtidigt som en begaran om gas begat's, da fordonet framfors vid en viss hastighet, kan anses vara skadlig for fordonet. Genom att framfOringskaraktaristika och/eller omgivningskonfiguration anvands som basis for att validera namnda signal uppnas ett robust, flexibelt och anvandarvanligt system. Enligt ett exempel kan fordonets hastig- het utgOra en parameter som paverkar namnda validering. Enligt ett exempel kan underlagets lutning utgOra en parameter som paverkar namnda validering. 13 Foretradesvis är styrenheten anordnad att, vid ej uppfyllt kriterium, forhindra autonom drift och/eller extern styrning av motorfordonet genom att stoppa sig- nalen fran det externa styrsystemet och ddrmed inte overfara namnda signal till manavreringssystemen. The same request, ie. a request for a brake at the same time as a request for a gas begat's, as the vehicle is being driven at a certain speed, can be considered harmful to the vehicle. By using performance characteristics and / or ambient configuration as a basis for validating said signal, a robust, flexible and user-friendly system is achieved. According to one example, the speed of the vehicle may be a parameter that affects the said validation. According to an example, the slope of the substrate can be a parameter that affects the said validation. Preferably, the control unit is arranged to, in the event of a criterion not being met, prevent autonomous operation and / or external control of the motor vehicle by stopping the signal from the external control system and thereby not transmitting said signal to the operating systems.
Ldmpligen ãr styrenheten anordnad att, vid ej uppfyllt kriterium, farhindra auto-nom drift och/eller extern styrning av motorfordonet genom att generera en signal for intern styrning av motorfordonet. Pa sá sdtt astadkommes en intern styrning av motorfordonet nar det pa forhand bestamda kriteriet ej är uppfyllt. Foretradesvis innefattar signalen for intern styrning styrparametrar, som minimerar risken far skador hos motorfordonet och objekt och/eller personer i dess omgivning. Exempelvis innefattar den interna styrningen styrparametrar som medfar att motorfordonet bromsas och/eller stannas/parkeras. For example, if the criterion is not met, the control unit is arranged to prevent automatic operation and / or external control of the motor vehicle by generating a signal for internal control of the motor vehicle. In this way, an internal control of the motor vehicle is achieved when the predetermined criterion is not met. Preferably, the signal for internal control includes control parameters that minimize the risk of injury to the motor vehicle and objects and / or persons in its vicinity. For example, the internal steering includes steering parameters that cause the motor vehicle to be braked and / or stopped / parked.
Enligt en aspekt av foreliggande uppfinning genererar styrenheten en signal for intern styrning av motorfordonet cla granssnittet och/eller det fordonsinterna styrsystemet under pagaende autonom drift och/eller extern styrning inte mot- tager nagon signal ails fran det externa styrsystemet. Pa sa satt kan det inter- na styrsystemet exempelvis stanna motorfordonet nal- den autonoma driften och/eller den externa styrningen av nagon anledning har avbrutits. Darmed skyddas bade motorfordonet och objekt och/eller personer i dess omgivning. According to one aspect of the present invention, the control unit generates a signal for internal control of the motor vehicle cla interface and / or the in-vehicle control system during ongoing autonomous operation and / or external control does not receive any signal ails from the external control system. In this way, the internal control system can, for example, stop the motor vehicle after autonomous operation and / or the external control has been interrupted for some reason. This protects both the motor vehicle and objects and / or people in its vicinity.
Enligt en aspekt av fareliggande uppfinning är styrenheten anordnad att, da autonom drift och/eller extern styrning har forhindrats och styrenheten har genererat en signal for intern styrning, generera en signal innefattande information om att det fordonsinterna styrsystemet styr motorfordonet. Styrenhet är lampligen vidare anordnad att overfara signalen innefattande information om att det fordonsinterna styrsystemet styr motorfordonet fran det fordonsinterna styrsystemet till det externa styrsystemet via granssnittet. Pa sa salt erhaller 14 det externa styrsystemet, och clamed operatoren, information om att det inte styr motorfordonet och varfOr det inte styr motorfordonet. According to one aspect of the present invention, the control unit is arranged that, when autonomous operation and / or external control has been prevented and the control unit has generated a signal for internal control, generate a signal comprising information that the in-vehicle control system controls the motor vehicle. The control unit is suitably further arranged to transmit the signal comprising information that the in-vehicle control system controls the motor vehicle from the in-vehicle control system to the external control system via the interface. On such salt, 14 the external control system, and the clamed operator, receives information that it does not control the motor vehicle and why it does not control the motor vehicle.
Enligt en utfOringsform av foreliggande uppf inning tillhandahdlles ett system, varvid namnda styrenhet är anpassad att ater tillâta autonom drift och/eller ex- tern styrning av ett motorfordon efter avbruten autonom drift och/eller extern styrning pa basis av en mottagen signal fran namnda externa styrsystem. According to an embodiment of the present invention, there is provided a system, wherein said control unit is adapted to allow autonomous operation and / or external control of a motor vehicle after interrupted autonomous operation and / or external control on the basis of a received signal from said external control system. .
Da den autonoma driften och/eller den externa styrningen har avbrutits kan en operator ater skicka en signal via det externa styrsystemet, där namnda signal innehdller en begaran om att ater fa framfOra fordonet autonomt och/eller externt. Harvid kravs det inte att en operator fysiskt forflyttar sig till namnda for-don fOr att aterigen kunna aktivera den autonoma driften och/eller den externa styrningen vilket skapar ett anvandarvanligt och tidseffektivt system. When the autonomous operation and / or the external steering has been interrupted, an operator can again send a signal via the external control system, where said signal contains a request to be able to drive the vehicle again autonomously and / or externally. In this case, it is not required that an operator physically move to said vehicle in order to be able to activate the autonomous operation and / or the external control again, which creates a user-friendly and time-efficient system.
Enligt en utfOringsform av fOreliggande uppf inning tillhandahalles ett system, varvid namnda styrenhet är anpassad att validera namnda signal innefattande begaran om att ater fâ framfOra fordonet autonomt och/eller externt fran namnda externa styrsystem. According to an embodiment of the present invention, a system is provided, wherein said control unit is adapted to validate said signal comprising the request to drive the vehicle again autonomously and / or externally from said external control system.
Signalen fran det externa styrsystemet innefattande begaran om att ater fâ framfOra fordonet autonomt och/eller externt innefattar lampligen operatorsgenererad information. FOretradesvis innefattar valideringen av signalen med begaran om att Ater fa framfOra fordonet autonomt och/eller externt, kontroll av operatOrens behOrighet. OperatOrens behOrighet och sdledes valideringen av signalen baseras lampligen pa den operatorsgenererade informationen i signalen. Genom att namnda signal valideras kan det sakerstallas att signalen kommer fran en operator som är tillaten att framfOra namnda motorfordon autonomt och/eller externt. Genom att validera namnda signal astadkommes ett sakert forfarande. The signal from the external control system, including the request to drive the vehicle again autonomously and / or externally, includes operator-generated information. Preferably, the validation of the signal with the request to re-drive the vehicle autonomously and / or externally, includes a check of the operator's authorization. The operator's authorization and thus the validation of the signal is suitably based on the operator-generated information in the signal. By validating said signal, it can be ensured that the signal comes from an operator who is allowed to drive said motor vehicle autonomously and / or externally. By validating said signal, a secure procedure is achieved.
Styrenheten är anordnad att kontrollera huruvida ndmnda operatorsgenererade information uppfyller kravet pa att namnda fordon ater far tas i bruk fOr autonom drift och/eller extern styrning. Enligt en utforingsform kan den operatorsgenererade informationen vara en specifik kod fran namnda operator. The control unit is arranged to check whether the said operator-generated information fulfills the requirement that the said vehicle can be used again for autonomous operation and / or external control. According to one embodiment, the operator-generated information may be a specific code from said operator.
Styrenheten kontrollerar saledes huruvida signalen uppvisar ran kod och tilla- ter att autonom drift och/eller extern styrning ater tas i bruk dâ signalen uppvisar ran kod. Enligt ett utforingsexempel kan den operatorsgenererade informationen vara en viss sekvens av utfOrda hand lingar av ndmnda operatOr. The control unit thus checks whether the signal has a code and allows autonomous operation and / or external control to be used again when the signal has a code. According to an exemplary embodiment, the operator-generated information may be a certain sequence of operations performed by said operators.
En operatOr kan avse en eller ett flertal personer. Alternativt kan en operator avse ett foretag eller en kund till fordonstillverkaren. An operator can refer to one or more people. Alternatively, an operator may refer a company or a customer to the vehicle manufacturer.
Enligt en utfaringsform av foreliggande uppf inning tillhandahalles ett system, van i det fordonsinterna styrsystemet ãr anordnat att avgara huruvida styrenhe- ten mottager en signal fran ett operatorsreglage hos motorfordonet. OperatOrs- reglaget hos motorfordonet utgOrs fOretradesvis av ett reglage som kan manovreras manuellt av operatoren nth' operatoren är lokaliserad inuti motorfordonets fOrarhytt. Med operator kan avses en forare av motorfordonet. Exempel pa operatorsreglage är ratt, gaspedal, bromspedal, vaxelspak, signaleringsor- gan etc. Enligt en utfOringsform utgors ett operatarsreglage av ett reglage som vid aktivering indikerar att operatoren onskar framfora fordonet manuellt. I de fall dâ styrenheten mottager signaler fran ett operatOrsreglage tillats inte auto-nom drift eller extern styrning av motorfordonet utan signalen fran det externa styrsystemet stoppas hos styrenheten. Genom att fOrhindra overforing av sig- naler fran det externa styrsystemet till manOvreringssystemen när styrenheten mottager en signal fran ett operatorsreglage, forhindras autonom drift och/eller extern styrning av motorfordonet sã fort indikation ges att en person befinner sig inuti motorfordonet och vill framfora motorfordonet manuellt. Nal- den autonoma driften och/eller externa styrningen ej finals erhalles manuellt drift av mo- torfordonet, genom att styrenheten styr manovreringssystemen i enlighet med den fran operatorsreglaget mottagna signalen. Pa sã salt sakerstdlls att ma- 16 nuell drift av motorfordonet alltid prioriteras framfor autonom drift och/eller extern styrning av motorfordonet. According to an embodiment of the present invention, there is provided a system, used in the in-vehicle control system is arranged to determine whether the control unit receives a signal from an operator control of the motor vehicle. The operator control of the motor vehicle is preferably a control that can be manually operated by the operator nth 'the operator is located inside the motor vehicle's cab. By operator can be meant a driver of the motor vehicle. Examples of operator controls are steering wheel, accelerator pedal, brake pedal, gear lever, signaling means, etc. According to one embodiment, an operator control consists of a control which, when activated, indicates that the operator wishes to drive the vehicle manually. In cases where the control unit receives signals from an operator control, automatic operation or external control of the motor vehicle is not permitted, but the signal from the external control system is stopped at the control unit. By preventing the transmission of signals from the external control system to the control systems when the control unit receives a signal from an operator control, autonomous operation and / or external control of the motor vehicle is prevented as soon as an indication is given that a person is inside the motor vehicle and wants to drive the motor manually. If autonomous operation and / or external control is not finalized, manual operation of the motor vehicle is obtained by the control unit controlling the maneuvering systems in accordance with the signal received from the operator control. In this way, it is ensured that manual operation of the motor vehicle is always prioritized over autonomous operation and / or external control of the motor vehicle.
Styrenheten styr saledes manovreringssystemen exempelvis pa basis av sig- naler fran antingen operatorsreglagen (manuell drift), eller fran det externa styrsystemet (autonom drift eller extern styrning). The control unit thus controls the maneuvering systems, for example on the basis of signals from either the operator controls (manual operation), or from the external control system (autonomous operation or external control).
