Technical Field

The present disclosure relates to the field of vehicle driving technologies, and in particular, to a vehicle guiding method, a vehicle guiding system, and a computer readable storage medium.

Background

The expressway or expressway is mainly characterized by completely controlling the entrance and exit, and adopting all/most of closed and three-dimensional junction facilities at two sides, and has the characteristics of high speed, high traffic volume and higher transportation economic benefit and social benefit. One or more service areas are usually arranged in an interval in the expressway so as to enable a driver to rest, charge, refuel and the like, thereby facilitating the driver and passengers to rest or process related matters and reducing the probability of traffic accidents caused by temporary stop.

However, in the actual driving process, when the driver drives on the expressway, a situation may sometimes occur in which the current/latest service area is missed due to unfamiliar road conditions. After missing the current/nearest service area, if the driver stops temporarily on the expressway or stops, backs or reverses on the expressway due to the fact that the distance of the next service area is far, traffic accidents are easily caused by dangerous driving behaviors, and accordingly life/property safety hazards are caused to the driver, passengers and other traffic participants.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments of the present application without making any inventive effort, are intended to be within the scope of the embodiments of the present application.

Currently, during actual driving on a highway or expressway, a driver often misses a service area when driving on the highway. For example: because the road conditions are unfamiliar, when a vehicle is about to enter a service area, a driver is distracted to miss a deceleration ramp, and the driving behavior of danger such as reverse driving, sudden braking and the like is caused because the driver can not change the lane when reacting, and traffic accidents are easy to occur with surrounding vehicles; after missing the current/nearest service area, if the driver stops temporarily on the expressway or stops, backs or reverses on the expressway because the distance of the next service area is far, traffic accidents are easily caused by dangerous driving behaviors, and dangerous behaviors such as fatigue driving, energy exhaustion in the middle of vehicle driving and the like can be caused because the driver cannot rest and the vehicle energy cannot be timely supplemented because the service area is missed. For such phenomena, the current driving functions cannot guide the vehicle into the corresponding service area in real time, and various dangerous driving behaviors are caused, so that life/property safety hazards are caused to drivers, passengers and other traffic participants.

In order to solve the above-mentioned problems, the embodiments of the present application provide a vehicle guidance method, which is applied to a controller and can be set in an electronic device having a logic calculation function, such as a server, a personal computer (Personal Computer, PC), a tablet computer, a smart phone, a personal digital assistant (Personal Digital Assistant, PDA), and the like.

Optionally, the controller may also be connected to a display unit on the electronic device or vehicle, which provides an interactive interface (e.g. user-operated interface) between the electronic device or vehicle and the user, or for displaying image data to a user reference. In this embodiment, the display unit may be a liquid crystal display or a touch display. In the case of a touch display, the touch display may be a capacitive touch screen or a resistive touch screen, etc. supporting single-point and multi-point touch operations.

In the embodiment of the present application, the display unit may display various travel-related information, and various information such as guide information generated by the controller.

The electronic device in the present embodiment may be used to perform each step in each vehicle guidance method provided in the present embodiment. The implementation of the vehicle guidance method is described in detail below by way of several embodiments.

Referring to fig. 1, fig. 1 is a flowchart of a vehicle guiding method according to an embodiment of the present application, and the method may include steps S100-S300.

Step S100, acquiring travel-related information acquired during travel of the target vehicle.

Wherein the travel related information includes one or more of a plurality of types of travel related information related to the vehicle, such as vehicle state information, occupant state information, remaining distance information, and road environment information.

The acquisition device can be arranged on the target vehicle, the acquisition device can comprise a plurality of different types of equipment which are respectively arranged at different positions on the vehicle, and after corresponding running related information is acquired, the controller can acquire the running related information through communication connection.

For example, the acquisition device may include a vehicle state acquisition device, such as a whole vehicle system, capable of acquiring vehicle state information related to a vehicle; a state monitoring device such as a fatigue detection system such as a DMS (Driver Monitor System, driver monitoring system) capable of monitoring occupant state information of an occupant such as a driver in a target vehicle; a distance measuring device, such as a navigation device with a high-precision map, etc., capable of detecting and calculating remaining distance information in a travel path of the target vehicle may be further included; an environment detection device, such as a notification module in a navigation device, may be further included to enable collection of road environment information on the travel path.

Step S200, generating guidance information of the target service area based on the travel related information.

The acquired one or more types of driving related information can be analyzed and processed to determine the state of the vehicle, the state of the passenger, the running process condition or the environment condition in front of the driving path, so that the guiding information for guiding the target vehicle to the target service area is generated when the state of the vehicle is poor, the state of the passenger is tired, the running process condition is poor or the environment condition in front of the driving path is poor.

Step S300, guiding or presenting the target vehicle with the target service area as a destination according to the guiding information.

The controller can guide or prompt the moving direction of the target vehicle in advance according to the guiding information by taking the target service area as a new destination of the target vehicle, and under the condition that the target vehicle is judged to be close to the target service area, the target vehicle can timely go to the target service area so as to enable passengers to rest, eat, charge, refuel and other operations in the target service area or provide information of the corresponding target service area for the vehicle driver/passenger to decide.

In the embodiment shown in fig. 1, the guiding information of the target service area can be provided for the target vehicle in time, so that the situation that the vehicle misses the service area is reduced, various dangerous driving behaviors caused by missing the service area are reduced, the occurrence rate of traffic accidents is effectively reduced, and the driving safety on the expressway is improved.

Optionally, referring to fig. 2, fig. 2 is a detailed flowchart of step S100 and step S200 provided in the embodiment of the present application, step S100 may include steps S110 to S150, and step S200 may include steps S210 to S250.

Step S110, acquiring the collected remaining energy information of the target vehicle.

The vehicle state detection device in the acquisition device can detect the energy information remained in the target vehicle, and the remained energy information can comprise different kinds of energy information such as the remained electric quantity information, the remained oil quantity information and the like due to different vehicle kinds. The controller may acquire, in real time, the remaining energy information transmitted in the vehicle state detection device through the communication connection, and the remaining energy information may be in various data formats, for example, a percentage data format, and the like.

Correspondingly, step S210, comparing the residual energy information with a preset energy threshold; if the remaining energy information is determined to be lower than the energy threshold, guidance information for guiding the target vehicle to the target service area is generated.

The corresponding energy threshold value, for example, 20%, may be preset according to the type, model, and other information of the target vehicle, and after the controller receives the remaining energy information, the remaining energy information may be compared with the energy threshold value, so as to analyze whether the remaining energy of the target vehicle can support the vehicle to travel to the destination. For example, when the remaining energy information is 10%, the remaining energy information is lower than the energy threshold, which indicates that the remaining energy of the target vehicle is less and cannot support the vehicle to travel to the destination, so in order to reduce dangerous behavior of the target vehicle caused by energy exhaustion during the traveling process, guiding or prompting guiding information for guiding the target vehicle to the determined target service area can be generated to provide information of the corresponding target service area for the vehicle driver/passenger to make a decision, so that the target vehicle can perform operations of charging, oiling and other supplementary energy sources in the target service area.

According to the method, whether the guiding information is generated or not can be judged according to the energy situation of the vehicle, so that when the vehicle energy situation does not support the vehicle to travel to the destination, the vehicle is effectively guided in advance when the situation that the target vehicle approaches the target service area is judged, and the situation that the vehicle misses the service area is reduced.

Or, in step S120, the collected driving duration information of the target vehicle is obtained.

The vehicle state detection equipment in the acquisition device can detect driving duration information of the target vehicle. The vehicle state detection device may count driving time of the target vehicle from when the target vehicle starts traveling to collect real-time driving duration information. The controller may acquire driving duration information transmitted in the vehicle state detection device in real time through a communication connection, and the driving duration information may be data representing a time length, for example, 4 hours, or the like.

Correspondingly, step S220, comparing the driving duration information with a preset duration threshold; if the driving duration information is determined to be higher than the duration threshold value, guiding information for guiding the target vehicle to the target service area is generated.

The corresponding duration threshold may be preset according to the physical condition of the passenger of the target vehicle, for example, when the passenger is younger and healthy, the set duration threshold may be 4 hours, when the passenger age exceeds 50, the set duration threshold may be 3 hours, etc., so that the corresponding duration threshold of the longest driving time may be set according to the bearing capacity of different people groups, and the duration threshold may also be set according to the current traffic regulations. After the controller receives the driving duration information, the driving duration information can be compared with a duration threshold value to analyze whether the target vehicle is driven for a long time. For example, when the driving duration information exceeds the duration threshold, it is indicated that the driving time of the target vehicle is too long, and the driver may have a situation of driving for too long or fatigue driving, so, in order to reduce dangerous behavior of driving for too long or fatigue driving, guiding or prompting guiding information for guiding the target vehicle into the determined target service area may be generated, so as to provide information of the corresponding target service area for the vehicle driver/passenger to make a decision, so that an occupant in the target vehicle can perform operations such as rest, eating, etc. in the target service area.

According to the method, whether the guiding information is generated or not can be judged according to the time situation that the driver drives the vehicle, so that when the driver drives for an extremely long time or is tired, the driver can effectively guide the vehicle in advance under the condition that the driver judges that the target vehicle approaches the target service area, and the situation that the vehicle misses the service area is reduced.

Or, step S130, acquiring the collected remaining distance information between the target vehicle and the initial destination.

The distance measuring equipment in the acquisition device can detect the distance between the target vehicle and the initial destination. The ranging apparatus may acquire the current position and the initial destination of the target vehicle and acquire a corresponding travel path from the map to determine corresponding remaining distance information. The controller may acquire the remaining distance information transmitted in the ranging device, for example, 100km or the like, in real time through a communication connection.

Correspondingly, step S230, comparing the remaining distance information with a preset distance threshold; if it is determined that the remaining distance information is higher than the distance threshold value, guidance information for guiding the target vehicle to the target service area is generated.

The corresponding distance threshold may be preset according to the average speed of the target vehicle, for example, when the average speed is 100km/h, the corresponding distance threshold may be set to 400km, and when the average speed is 110km/h, the corresponding distance threshold may be set to 440km, that is, the target vehicle may need to travel for 4 hours to reach the initial destination. When the controller receives the remaining distance information, the remaining distance information may be compared with a distance threshold to analyze a remaining travel duration of the target vehicle to the initial destination. For example, when the average speed is 100km/h, the distance threshold is 400km, and the remaining distance information is 600km, the remaining driving distance is longer, the remaining driving duration is 6 hours, the driving time is longer, and a long distance/long time form is needed to reach the destination. Therefore, in order to reduce dangerous behaviors such as fatigue driving, energy exhaustion and the like generated during long distance/long time driving, guiding information for guiding the target vehicle into a determined target service area can be generated for guiding or prompting, so that information of the corresponding target service area is provided for vehicle driver/passenger decision, and passengers in the target vehicle can rest, eat, supplement energy and the like in the target service area.

The method can judge whether the guiding information is generated according to the flow condition of the vehicle in the running process, so that the vehicle is effectively guided in advance under the condition that the target vehicle is judged to be close to the target service area when long-distance/long-time running is required, and the condition that the vehicle misses the service area is reduced.

Or, step S140, acquiring occupant state information of an occupant in the acquired target vehicle.

The state monitoring equipment in the acquisition device can monitor the driving state of an occupant in the target vehicle. The state monitoring equipment can monitor various behaviors such as driving fatigue, distraction, call receiving, feeding and the like of the passengers through technologies such as image processing and the like, and corresponding passenger state information is obtained. The controller may acquire the occupant state information transmitted in the state detection apparatus in real time through a communication connection, and the occupant state information may include a degree of fatigue of an occupant in the target vehicle, and the degree of fatigue may include various description modes, such as light fatigue, moderate fatigue, or heavy fatigue, etc.

Accordingly, in step S240, if it is determined that the fatigue degree reaches the preset degree threshold, guiding information for guiding the target vehicle to the target service area is generated.

The degree threshold may be set to be moderately tired, and when the fatigue degree in the passenger state information reaches moderately tired, the fatigue degree representing the driving state of the passenger is serious, and needs to be rested, so in order to reduce the dangerous behavior of fatigue driving, guiding information for guiding the target vehicle to a determined target service area may be generated for guiding or prompting, so as to provide information of the corresponding target service area for the vehicle driver/passenger to make a decision, so that the passenger in the target vehicle can perform operations such as rest, feeding and the like in the target service area.

In the above mode, whether the guiding information is generated or not can be judged according to the personnel condition in the vehicle, so that when the condition of the passenger is poor, the vehicle is effectively guided in advance when the condition that the target vehicle approaches the target service area is judged, and the condition that the vehicle misses the service area is reduced.

Or, step S150, acquiring the road environment information in the travel path of the collected target vehicle.

The environment detection device in the acquisition device can acquire the path information of the target vehicle running to the initial destination from the navigation system, so as to acquire the road environment information corresponding to the road in the running path in front of the target vehicle. The controller may acquire road environment information transmitted in the environment detection device in real time through a communication connection, where the road environment information may include information such as weather conditions of a driving path, road surface conditions of the driving path, etc., for example, a certain area in a driving path of a target road is raining, a certain road section in driving is collapsed, etc.

Accordingly, in step S250, if it is determined that the weather condition of the road environment information is the preset bad weather, or if it is determined that the road surface condition of the road environment information is the preset non-passing road section, the guiding information for guiding the target vehicle to the target service area is generated.

The bad weather and the non-passing road section can be set correspondingly according to the actual conditions of the road section, for example, when the weather condition is snowstorm, stormy weather or the road surface condition is collapse and cannot pass, the running safety of the representation running path is lower, and the representation running path is not suitable for continuous running. Therefore, in order to reduce adverse effects of external environmental factors on driving safety, guiding information for guiding the target vehicle into the determined target service area may be generated to guide or prompt, so as to provide information of the corresponding target service area for vehicle driver/passenger decision, so that passengers in the target vehicle can wait for normal environmental conditions in the target service area and then drive.

According to the method, whether the guiding information is generated or not can be judged according to the environment condition in front of the vehicle, so that when the situation that the front environment is bad and the target vehicle is judged to be close to the target service area, the vehicle is effectively guided in advance, and the situation that the vehicle misses the service area is reduced.

In the embodiment shown in fig. 2, various schemes for determining whether to conduct guidance or presentation according to the travel-related information are provided, and the risk in driving can be reduced from a plurality of different aspects.

Optionally, referring to fig. 3, fig. 3 is a detailed flowchart of another step S200 provided in the embodiment of the present application, and steps S261-S263 may be included in step S200.

In step S261, the current position information and driving requirement of the target vehicle are acquired.

When the guiding information is required to be generated to guide or prompt the target vehicle, the position information and the driving requirement of the current target vehicle can be acquired in real time. The position information may be obtained from a positioning system in the target vehicle, the driving requirement may be obtained from interaction between the controller and an occupant in the target vehicle, for example, by selecting a corresponding requirement through a key, or by analyzing the voice of the occupant, the corresponding requirement may be obtained, and may also be directly determined according to the actual situation of the vehicle.

For example, the driving demand may be: when the residual energy information of the vehicle is low, the automatic generation of the supplementary requirement, such as charging piles or gas stations, is needed for charging or oiling; time requirements selected by the occupant, e.g., fewer vehicles, no longer queuing time, etc.; a rest requirement, such as having a parking space, being available for parking and rest, etc.; eating requirements, such as having a dining area, being able to eat, etc.; accommodation requirements, such as areas with hotels, etc., can be accommodated; or shopping requirements, for example having a recreational area such as a mall, etc., enabling shopping, etc.

Step S262, inquiring in a plurality of surrounding service areas according to the position information and the driving requirement, and determining a target service area.

The service area may be an area disposed around the highway, for example, various service areas, or may be other areas, for example, various different types of areas disposed according to the needs of the customer, such as accommodation, shopping, etc.

Wherein, a plurality of peripheral service areas in the peripheral range of the target vehicle can be determined according to the position information, the peripheral range can be set as a plurality of ranges such as 100km, 150km and the like, and the peripheral range can be set and modified according to the actual condition of the road section and the requirements of passengers. Therefore, the position information and the driving requirement can be combined to inquire in a plurality of surrounding service areas, the driving requirement is met, the driving time of the target vehicle is shortest, or the service area with the shortest driving path is taken as the target service area, for example, when the driving requirement is that a charging pile is needed, the rest and the eating are needed, the service area with the shortest driving time of the target vehicle or the shortest driving path and provided with the charging pile, the parking space and the dining area can be selected as the target service area in the plurality of surrounding service areas.

When the occupant does not select the service area and there is no automatically generated related demand, the occupant may simply query the service area based on the position information, and select the service area having the shortest travel time or the shortest travel path for the target vehicle to travel in the surrounding service area as the target service area.

Step S263, corresponding guiding information is generated according to the target service area.

Wherein, the new driving route can be planned by taking the target service area as a new destination of the target vehicle, and corresponding guiding information can be generated.

In the embodiment shown in fig. 3, the corresponding area can be determined as the destination according to the actual position and the driving requirement of the vehicle to generate the guiding information, so that the real-time performance and the effectiveness of the guiding information are effectively improved.

Optionally, referring to fig. 4, fig. 4 is a detailed flowchart of step S300 provided in the embodiment of the present application, and step S300 may include steps S310 to S320.

Step S310, pushing the guide information to the occupant in the target vehicle.

After the corresponding guiding information is generated, the guiding information can be pushed to an occupant in the target vehicle, and the pushing mode can be information display in a display unit for sending the guiding information to the target vehicle or voice broadcasting and the like.

In step S320, if confirmation information fed back by the occupant based on the guidance information is received, the target vehicle is guided or presented with the target service area as a destination.

The method comprises the steps of receiving relevant information fed back by an occupant based on guide information, for example, when the guide information is displayed on a display unit, acquiring key information of the occupant selection display unit as feedback information, when the guide information is voice broadcasting, acquiring voice information fed back by the occupant based on the guide information as feedback information, and processing the feedback information to determine whether the characterization of the voice information is confirmation or negation. After the confirmation information of the passenger is acquired, the target service area is taken as a new destination of the target vehicle, and the target vehicle is guided or prompted according to the guiding information.

In the embodiment shown in fig. 4, the passenger can be guided or prompted in real time through interaction such as information prompting, pushing and the like, so that the passenger is informed of the corresponding guiding condition in advance, and the success rate of guiding the vehicle is improved.

Optionally, referring to fig. 5, fig. 5 is a detailed flowchart of step S320 provided in the embodiment of the present application, and step S320 may include steps S321-S326.

In step S321, the lane condition of the target vehicle is determined.

When the vehicle is guided or presented, the target vehicle may need to change lanes due to the relationship between the lane in which the vehicle is located and the high-speed exit. Therefore, the acquisition device can also comprise sensing equipment, such as laser radar, a camera, millimeter wave radar and the like, and can detect the lane where the target vehicle is actually located currently so as to enable the controller to determine the lane condition of the target vehicle.

Step S322 determines whether the target vehicle has a lane change demand based on the lane condition and the guidance information.

The lane data of the planned path in the guiding information can be analyzed first, and the lane data is analyzed in combination with the lane condition to determine whether the target vehicle has a lane change requirement. For example, when the lane of the target vehicle is a left lane and the lane data in the guidance information is a right lane before reaching the target service area, the target vehicle has a lane change requirement.

In step S323, if it is determined that the target vehicle has a lane change requirement, a lane change value of the target vehicle is determined.

The lane change value characterizes the success rate of lane change of the target vehicle, and can be calculated by combining with a plurality of influence factors influencing the lane change condition.

In step S324, it is determined whether the target vehicle satisfies the lane change condition based on the lane change value and the preset lane change threshold.

The lane change threshold may be a threshold determined according to a historical lane change condition of the target vehicle, for example, taking a probability format as an example, the lane change threshold may be set to 0.9, so that when the lane change value is higher than 0.8, that is, the success rate of representing the lane change is higher, and the lane change condition is satisfied. When the lane change value is lower than 0.8, the success rate of representing lane change is lower, and the lane change condition is not satisfied.

In step S325, if it is determined that the target vehicle satisfies the lane change condition, a corresponding lane change instruction is generated based on the guidance information.

When the target vehicle meets the lane change condition, a corresponding lane change instruction can be generated according to lane data in the guide information, and the lane change control processing of the vehicle can be performed only when the lane change success rate is high, so that adverse influence on driving safety caused by lane change when the lane change success rate is low is reduced.

In step S326, the target vehicle is controlled to change lanes based on the lane change instruction to guide the target vehicle to move with the target service area as a destination.

The lane change instruction is used for automatically driving the target vehicle, and the target vehicle is controlled to change lanes before reaching the lane line solid line of the target service area, so that the target vehicle is guided to move correspondingly with the target service area as a destination.

In the embodiment shown in fig. 5, the target vehicle can be guided into the corresponding lane in advance according to the actual situation of the target vehicle, so that dangerous driving behaviors such as reverse running, sudden braking and the like caused by the fact that the vehicle is not in the way of changing can be reduced, the occurrence rate of traffic accidents can be reduced, and meanwhile, the real-time performance of guiding or prompting the vehicle can be improved, so that the situation that the vehicle misses the service area can be reduced.

Optionally, referring to fig. 6, fig. 6 is a detailed flowchart of step S323 provided in the embodiment of the present application, and step S323 may include steps S3231-S3232.

Step S3231, acquiring at least one of traffic condition information in a travel path of the target vehicle, a travel speed of the target vehicle, traffic flow information within a preset range of the target vehicle, and lane information.

In the driving process, the driving speed of the target vehicle, the surrounding traffic information, the lane information and the like affect the comfort in lane change, so that a plurality of influencing factors affecting the lane change, such as various information including traffic condition information in the driving path of the target vehicle, the driving speed of the target vehicle, traffic information in a preset range of the target vehicle, and lane information, can be obtained.

For example, the traffic condition information may be a vehicle congestion condition in a road section ahead of the target vehicle collected by the navigation device in the collection device, so as to perform lane change processing in advance when the front road section is congested, and reduce the adverse condition that the target vehicle cannot be guided into the entrance of the target service area due to the traffic congestion before the target vehicle runs to the lane line solid line of the service area.

And step S3232, performing weighted calculation on at least one of traffic condition information, running speed, traffic flow information and lane information based on the weight information to obtain a lane change value.

The weight information may be information determined according to the influence degree of each factor when the vehicle history changes lanes, and may be calculated by weighting according to the weight information in combination with traffic condition information, running speed, traffic flow information, lane information, and the like, so as to obtain a corresponding lane change value. For example, when calculating in combination with the traffic condition information, the traveling speed, the traffic flow information, and the lane information, the weight value of the traffic condition information may be 0.2, the weight value of the traveling speed may be 0.2, the weight value of the traffic flow information may be 0.3, and the weight value of the lane information may be 0.3.

In the embodiment shown in fig. 6, lane changing can be reasonably estimated and calculated according to the surrounding situation and the front situation of the target vehicle, so as to improve the success rate of lane changing of the vehicle.

Optionally, referring to fig. 7, fig. 7 is a flowchart of another vehicle guiding method according to an embodiment of the present application, and the method may further include steps S410 to S420.

In step S410, if it is determined that the target vehicle moves within the vicinity of the target service area, a deceleration command is generated.

In order to enable the target vehicle to smoothly travel into the target service area, a corresponding deceleration command may be generated when the target vehicle is detected to move within the vicinity of the target service area. The critical range of the target service area may be set according to the actual road condition of the target service area, for example, may be set to 500m, that is, 500m before the entrance of the target service area, and a corresponding deceleration instruction is generated.

Optionally, the deceleration instruction may further include a corresponding prompt message, so as to prompt, by means of voice broadcasting or screen display, that the passenger is about to reach the target service area, so as to request the driver to take over the target vehicle, and achieve subsequent operations of parking, refueling, charging, and the like.

Step S420 controls the target vehicle to decelerate to the road speed limit value of the target service area based on the deceleration instruction.

Optionally, automatic driving can be performed according to the deceleration instruction, so as to control the target vehicle or prompt a driver of the target vehicle to decelerate to a road speed limit value of the target service area, and reduce potential safety hazards caused by over-high speed.

In the embodiment shown in fig. 7, it is possible to control or prompt the deceleration of the target vehicle in the vicinity, and smoothly drive into the target service area.
