Definitions
- the invention relates to a method by means of which it is recognized in a parked motor vehicle whether this has been rammed, ie whether a collision has taken place, and / or whether the motor vehicle has been moved by external influence.
- the method is provided for collision detection when the motor vehicle is switched off, that is, when the motor vehicle is in an ignition-off state, i. E. whose ignition system is switched off, which can be detected, for example, at a terminal 15-off state according to DIN 72552.
- EP 2 362 362 A1 a method for charging electric vehicles in geographically distributed charging stations is known.
- the charging process of a motor vehicle in the charging station is monitored and in the event of an interruption, disturbance or deviation of the charging process from a predetermined course, a picture of the motor vehicle in the charging station is taken by means of a camera.
- the fraud and manipulation security can be increased.
- a fault during the charging process is detected on the basis of a given charging characteristic.
- the disadvantage of this system is that a collision of the motor vehicle with an object that rams it does not necessarily disturb the charging process itself, but instead, for example, only an intermediate circuit of the high-voltage system is damaged. In other words, collision detection with the system is not possible.
- a collision detection when the vehicle is stationary in addition to the emergency shutdown of a Höchvoltsystems also offer other benefits. For example, an airbag can be triggered more reliably.
- the invention has for its object to reliably detect in a parked motor vehicle, whether this was rammed and / or moved.
- the object is solved by the subject matters of the independent claims.
- Advantageous developments of the invention ' result from the features of the dependent claims.
- the method according to the invention is based on the knowledge that sensors are available in a motor vehicle by means of which the relative position of a motor vehicle with respect to vehicle-external reference objects can be determined. Upon detection of a change in the relative position to these reference objects is in a parked vehicle clear that this must have been rammed by another object and / or has been moved by external influence.
- the method according to the invention accordingly provides that a control device of the motor vehicle, for example a control device or a central computing device, receives from a sensor device of the motor vehicle at least one sensor signal which is just dependent on a relative position of the motor vehicle relative to at least one external reference object.
- a reference object is preferably a stationary object, in particular a solid object.
- the at least one sensor signal is checked for whether it indicates a collision and / or movement.
- the at least one sensor signal according to an embodiment is compared with at least one predetermined signal pattern.
- a signal pattern describes a waveform that can arise when the Motor vehicle is rammed or moved in a predetermined manner.
- at least one predetermined threshold value can also be used. Depending on the sensor signal, a collision can already be concluded on the basis of exceeding or falling below a certain threshold value.
- the threshold value therefore specifies a value interval within or outside which the sensor signal must be located. It can also be based on a bilaterally limited value interval.
- Another possibility is to compare at least one sensor signal with at least one predetermined signal template.
- a signal template does not describe a precise course, but rather specifies an interval or a corridor or a tube within or outside of which the sensor signal must be located so that collision is not detected.
- At least one control command for initiating a protective measure is transmitted to at least one device of the motor vehicle in the case of a difference determined by the comparison.
- a high-voltage system and / or a charging system for a traction battery of the motor vehicle is switched off.
- the charger may be an inductive AC-based charger or a DC (DC) DC charger.
- a high-voltage voltage is in particular an electrical voltage that is more than 60 V.
- the invention has the advantage that when parking the motor vehicle, in particular when the motor vehicle is switched off, a collision and / or movement can be detected even if the crash sensor system is not operated to trigger the airbag.
- each sensor signal is generated by a sensor device which also sends its sensor signal to at least one further component of the motor vehicle, which on the basis of the sensor signal provides a function different from the collision detection in the motor vehicle.
- a sensor device that already exists for other functionalities in the motor vehicle is used. Then it is not necessary in the motor vehicle dedicated circuit technology for carrying out the method according to the invention provide.
- This can be a sensor device which is also operated when the motor vehicle is switched off or it can also be provided that a sensor device is switched on permanently or at intervals, which is not operated to provide the other functionalities while the motor vehicle is stationary or switched off.
- a navigation device can be activated to read a speed sensor of the wheels of the motor vehicle and to detect a rolling of the motor vehicle, as it is also used for tunneling, for example, if no GPS signal ( GPS - Global Positioning System) is available.
- GPS Global Positioning System
- a positioning signal of a positioning sensor system of an inductive charging system is used as a sensor signal.
- a positioning signal is also available when the motor vehicle is switched off when it is above an inductive charging station and is subjected to an alternating magnetic field of a bottom-side primary coil.
- the positioning sensor system is provided in the prior art for correctly positioning the motor vehicle over the primary coil before the charging process, so that the secondary coil of the charging system provided in the motor vehicle is arranged as close as possible above the primary coil. By means of this positioning sensor can also be monitored after the beginning of the charging process, whether a position or position of the motor vehicle changes.
- a further advantageous development is to also use an impedance value signal of an impedance measuring device of the inductive charging system for motion detection.
- the impedance value changes as the relative position of the secondary coil with respect to the primary coil changes.
- a navigation system or another positioning system of the motor vehicle can also be used to receive a GNSS signal as a sensor signal (GNSS - Global Navigation Satellite System).
- GNSS Global Navigation Satellite System
- a further advantageous embodiment results when a distance signal of an ultrasonic sensor and / or a radar sensor and / or an image signal of a camera is received as a sensor signal. Based on these signals, a movement of the motor vehicle can already be detected by a few centimeters.
- false tripping is effectively prevented by the at least one control command for initiating the security measure being generated only if at least one predetermined plausibility condition is met.
- a plausibility condition is that a charge mode provided for charging a traction battery of the motor vehicle must be active, in which electrical energy is transferred to the traction battery via a charging system.
- Another plausibility condition results from a wired charging. Thereafter, the safety measure is initiated only when a collision and / or movement is detected and a charging plug is plugged.
- Another plausibility condition is that a parking brake of the motor vehicle must be involved. Again, this is an indication that the driver does not intend to move his motor vehicle.
- the parking brake When charging a traction battery, the parking brake must be tightened and / or the drive otherwise blocked.
- the motion monitoring should be activated. If a high voltage component is active with the ignition off, e.g. a stationary air conditioning, so is also an indication of a parking operation. In this case, the airbag control unit is not active because of the switched off ignition, so that a special protection in a collision is also advantageous here.
- Which plausibility condition or combination of plausibility conditions for a particular motor vehicle results in the most robust motion detection can be determined by a person skilled in the art on the basis of tests.
- the sensor signals are examined by means of a signal pattern, a value interval and / or a signal template.
- Signal patterns, value intervals and signal templates are preferably designed such that they describe a predetermined pulse and / or a predetermined acceleration and / or a predetermined displacement path and / or a predetermined time profile relating to the respective sensor signal. This can in each case be a description of a normal state in which there is no collision is present, or just a state with collision. In particular, it should be ensured that a distinction is made between a collision and a jolting of the motor vehicle, as it can cause a person by rockers on the motor vehicle. Suitable signal patterns / value intervals / signal templates can be determined, for example, in tests and crash tests.
- a further embodiment of the method provides that, after starting the motor vehicle, a current position value of the motor vehicle is compared with a position value stored before or during a previous shutdown. It is therefore checked whether the motor vehicle has changed its position during a parking phase. If a difference is detected between the two position values, then the at least one control command for initiating the safety measure is generated and / or the driver is warned, e.g. by activating a warning lamp. This can at least prevent the driver from starting with a possibly damaged high-voltage system or otherwise damaged motor vehicle.
- the invention also provides a motor vehicle which is designed to carry out an embodiment of the method according to the invention.
- the motor vehicle has a corresponding control device and a sensor device, which is designed to generate a sensor signal when the motor vehicle is at a standstill, which is dependent on a relative position of the motor vehicle with respect to at least one vehicle-external reference object.
- an inductive charging device for a traction battery of the motor vehicle, which comprises a secondary coil for an inductive charging.
- a positioning device for positioning the secondary coil with respect to a vehicle-external primary coil is designed to send its positioning signal also to the control device, so that on. Basis of this positioning signal and a collision on the motor vehicle can be detected.
- FIG. Shows a schematic representation of an embodiment of the motor vehicle according to the invention.
- the exemplary embodiment explained below is a preferred embodiment of the invention.
- the described components of the embodiment each represent individual features of the invention that are to be considered independently of each other, which also develop the invention independently of one another and thus also individually or in a different combination than the one shown as part of the invention ,
- the described embodiment can also be supplemented by further features of the invention already described.
- the figure shows a motor vehicle 10, which may be, for example, a motor vehicle, in particular a passenger car.
- the motor vehicle 10 has a high-voltage system 12, whose (not shown in detail) high-voltage battery is being charged by a charging system 14.
- the charging system 14 may include a secondary coil 16 receiving an alternating magnetic field from a stationary primary coil 18.
- the motor vehicle 10 has been parked by a driver (not shown) above the primary coil 18.
- the driver has used a positioning system 20 which has used fixed markings 22 of the primary coil 18 as landmarks.
- a foreign vehicle 24 is parked in the example shown.
- another vehicle-foreign object 26 such as a street lamp.
- the motor vehicle 10 is rammed by another motor vehicle 28, which thereby transmits a pulse 30 to the motor vehicle 10 which is so large that, for safety reasons, the high-voltage system 12 should be switched off.
- the motor vehicle 10 automatically detects the collision at which the pulse 30 is transmitted to the motor vehicle 10.
- a monitoring device 32 is provided in the motor vehicle 10, which may be, for example, a control device or a central computing device of the motor vehicle.
- the monitoring device 32 can use a positioning signal P of the positioning device 20 for collision detection.
- the monitoring device 32 can receive, for example, a movement signal B from a navigation assistance system 34, which generates the movement signal B, for example by means of a rotation sensor 36, which detects a rotational movement of a wheel 38 of the motor vehicle 10 triggered by the transmission of the pulse 30.
- the monitoring device 32 may also receive a distance signal A from a distance sensor 40, for example an ultrasonic sensor or radar sensor, which measures a distance 42 to the other vehicle 24.
- the monitoring device 32 can also receive a camera signal or video signal V from a camera 44, whose detection range 46 can be directed to the object 26, for example.
- the monitor 32 may also receive a GPS signal G from a locator 48, such as a GPS receiver, which receives a signal from one or more GPS satellites 50.
- the monitoring device 32 can determine that the motor vehicle 10 has been rammed so hard that the high-voltage system 12 has to be switched off.
- the monitoring device 32 therefore generates a control command S, by means of which, for example, contactors, via which the high-voltage battery is connected to a DC link of the high-voltage system 12, are opened.
- the monitoring device 32 compares the received signals with respectively predetermined desired progressions of these signals or with a template of, for example, time-dependent maximum values and minimum values which may not exceed or fall below the signal. Thresholds can also be used.
- the markings 22, a road 52 over which the wheel 38 rolls, the foreign vehicle 24, the object 26 and the satellite 50 represent reference objects, by means of which the monitoring device 32 recognizes a respective movement of the motor vehicle 10 via the received signals and from this Rolls or a shock on the vehicle 0 detects.
- the invention makes it possible in general to detect a collision or a crash when charging an electric / plug-in hybrid vehicle during wireless charging. As a result, a rapid shutdown of the high-voltage system in a crash in the state, especially in the ignition-off state of the motor vehicle, possible.
- the detection of the movement of the vehicle by a crash is preferably carried out by a movement of the motor vehicle based on a functionality for positioning the motor vehicle on the inductive pallet with the primary coil 18 is used.
- a further existing system of the motor vehicle 10 which is also active at ignition-off or can simply be switched on, such as a driver assistance system 34 or a GPS positioning system 48 for generating GPS data G. can also be detected a movement of the motor vehicle, if the movement is also large enough.
- this recognition can also be used in addition to ignition, that is redundant to the control unit for the crash detection.
- the advantage hereby is that the use of already existing functions for detecting a crash event in the event of ignition-off and consequently an increase in safety is given. Also, this functionality can be used as a redundant system with ignition-on in stand / when charging.
- the detection of movement by the positioning sensor system 20 of the contactless charging system can also be combined with, for example, the evaluation of a GPS signal, which also indicates this movement with sufficient movement of the vehicle from one position to another.
- the input condition for the crash detection should be that the vehicle is in the charging mode.
- the motor vehicle does not move or it must not be possible to produce the ride readiness.
- the brake is applied accordingly. With one of these input conditions, or a combination of these conditions, it is possible to correctly and safely identify the situation so that there is no misdiagnosis in other operating conditions.
- the described collision and / or motion detection according to the invention can be useful if, for example, a high-voltage system is active due to auxiliary air conditioning.
- Other vehicle functions may also be provided in which the high-voltage system switched ignition of the motor vehicle and are activated without a person in the vehicle or in the vicinity of the motor vehicle.
