Description

Technical Field

[0001] This application relates to the field of joint control technology for vehicle subsystems with different functions in the new energy industry, and particularly to a method and device for intelligent heating of a vehicle steering wheel, a vehicle, a storage medium, and a program. Background Art

[0002] When driving in winter, especially in the north, the cold environment makes the driver's hands relatively stiff, resulting in inflexible operation of the steering wheel and prone to danger. Thus, the heating technology for the steering wheel appears. The basic principle is to place a layer of resistance wire inside the leather wrapping the steering wheel, and the power supply wire supplies power to the resistance wire through the position where the lower side of the steering wheel is connected to the rotating shaft to complete heating. However, in the prior art, most of them heat the entire steering wheel, which causes power consumption waste in some areas of the steering wheel that are not often held, or heat in certain areas (such as the 3 o'clock or 9 o'clock direction of the steering wheel), but this is only meaningful for drivers who are used to holding the steering wheel in the 3 o'clock or 9 o'clock direction area. For drivers with other area habits or drivers who change the holding area during driving, it cannot play a heating role.

[0003] However, when looking at racing competitions, it will be found that in order to ensure the speed of the vehicle, there is a lot of air circulation between the cockpit of many racing cars and the outside world. This means that when many racers compete in winter or in cold places, the heat in the cockpit and the temperature of the hands will be lost very seriously. After this situation occurs, it will seriously affect the race results of the racers.

[0004] Therefore, how to provide a method for intelligent heating of the steering wheel for drivers in the track scenario is an urgent problem to be solved. Summary of the Invention

[0005] The embodiments of this application provide a method and device for intelligent heating of the steering wheel in the vehicle track mode, which can meet the functional requirements of efficiently and accurately warming hands following the driver's holding position in the track scenario through the joint control of the intelligent cockpit domain controller and the steering wheel sub-controller, improve the intelligence, flexibility, and accuracy of the heating function, and reduce unnecessary energy consumption.

[0006] In a first aspect, the embodiments of this application provide a method for intelligent heating of the steering wheel in the vehicle track mode. The method is applied to the intelligent cockpit domain controller of the target vehicle, and the intelligent cockpit domain controller is communicatively connected to the steering wheel sub-controller. The method includes:

[0007] Based on the cockpit environmental temperature of the target vehicle, determine whether the optimized heating function for the track mode is enabled with the steering wheel controller. The optimized heating function for the track mode refers to the function of intelligently heating the steering wheel of the target vehicle by combining the intelligent cockpit domain controller and the steering wheel controller in a track scenario;

[0008] If the optimized heating function for the track mode is enabled, obtain the historical dynamic information of the driver of the target vehicle in the current track scenario. The dynamic information includes all the steering wheel gripping positions of the driver in the current track scenario, the scene nodes and occurrence times when the steering wheel gripping positions change, and the lap time and elapsed time of the driver in the current track scenario;

[0009] Based on the historical dynamic information of the driver in the current track scenario, predict the steering wheel time distribution characteristics applied to the current track scenario.

Many race car drivers have clearly pointed out after the race that during the race, their fingers lost temperature very seriously, resulting in very stiff fingers and making it difficult to perform refined operations. This also shows that in a race car competition, there is a need for steering wheel heating, and it is urgent; however, due to the strict requirements of the race car itself for the body weight, it is difficult to improve from the structure of the steering wheel or the heating equipment in the vehicle cockpit. Therefore, this method specifically combines the intelligent cockpit domain controller and the steering wheel controller to jointly control the steering wheel heating, and realizes the efficient and accurate hand-warming requirement while ensuring that the weight of the equipment itself does not exceed the standard, improves the intelligence, flexibility and accuracy of the heating function, and reduces unnecessary energy consumption.

[0030] The system architecture applied in the embodiments of the present application will be introduced below. It should be noted that the system architecture and business scenarios described in the present application are for more clearly explaining the technical solutions of the present application, and do not constitute a limitation on the technical solutions provided by the present application. Those of ordinary skill in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solutions provided by the present application are equally applicable to similar technical problems.

[0031] Please refer to Figure 1 , Figure 1 which is a schematic diagram of the architecture of a steering wheel heating control system provided by an embodiment of the present application. The steering wheel heating control system includes an intelligent cockpit domain controller 201 and a steering wheel sub-controller 202. The execution subject of the method provided by the embodiment of the present application is the intelligent cockpit domain controller 201 with information processing capabilities; the intelligent cockpit domain controller 201 establishes a communication connection with the steering wheel sub-controller 202. The steering wheel sub-controller 202 is used to control the steering wheel heating device in the vehicle. The heating principle of the steering wheel heating device is resistance wire heating, which is placed in four areas on the outer periphery of the steering wheel and can be simply divided into four areas: up, down, left, and right.

[0032] The intelligent cockpit domain controller 201 includes: a first interaction layer 2011, a processing layer 2012, and a second interaction layer 2013. The first interaction layer 2011 is mainly used to obtain the environmental temperature of the vehicle cockpit, and determine whether to enable the track mode optimization heating function through the environmental temperature of the vehicle cockpit and the steering wheel sub-controller 202. The processing layer 2012 is mainly used to process the dynamic information of the driver in previous races, predict the steering wheel time distribution characteristics applied to the current track scenario, and formulate a steering wheel heating strategy corresponding to the steering wheel time distribution characteristics. The second interaction layer 2013 is mainly used to send the steering wheel heating strategy to the steering wheel sub-controller 202, so that the steering wheel sub-controller executes the steering wheel heating strategy to realize the function of intelligent heating of the steering wheel of the target vehicle.

[0033] The above intelligent cockpit domain controller 201 and steering wheel sub-controller 202 can be integrated in the vehicle, can also be integrated outside the vehicle, or one can be set in the vehicle and the other can be set outside the vehicle. The embodiments of the present application do not make any limitations on this.

[0034] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of a method for intelligent heating of a steering wheel in a vehicle track mode. The method is applied to the intelligent cockpit domain controller of the target vehicle. The intelligent cockpit domain controller is in communication connection with the steering wheel sub-controller. The method includes but is not limited to the following steps:

[0035] Step S201: Determine whether the optimized heating function for the track mode is enabled based on the cockpit environmental temperature of the target vehicle and the steering wheel sub - controller.

[0036] The optimized heating function for the track mode refers to the function of jointly controlling the steering wheel of the target vehicle for intelligent heating by the intelligent cockpit domain controller and the steering wheel sub - controller in a track scenario.

[0037] When the cockpit environmental temperature of the target vehicle is lower than the low - temperature threshold, the intelligent cockpit domain controller sends a request message to enable the optimized heating function for the track mode to the steering wheel sub - controller. If a positive response message regarding the optimized heating function for the track mode is received from the steering wheel sub - controller, it is determined that the optimized heating function for the track mode is enabled, and then the subsequent steps are executed. The steering wheel heating function is jointly controlled by the intelligent cockpit domain controller and the steering wheel sub - controller to achieve intelligent heating.

[0038] Step S202: If the optimized heating function for the track mode is enabled, obtain the historical dynamic information of the driver of the target vehicle in the current track scenario.

[0039] The dynamic information includes all the steering wheel gripping positions of the driver in the current track scenario, the scene nodes and occurrence times when the steering wheel gripping positions change, and the lap time and elapsed time of the driver in the current track scenario.

[0040] In an optional implementation manner, the source of the driver's dynamic information comes from the information database belonging to the current driver of the target vehicle. The information database includes cockpit images of the current driver in historical races. Among them, the cockpit images are analyzed to obtain the driver's dynamic information in historical races, and the dynamic information is also stored in the information database. After the end of this race, the driver's dynamic information in this race will also be stored in the information database. Generally speaking, each driver has different driving habits, so the corresponding historical dynamic information exists in different regions. Mapped to the embodiments of the present application, the gripping regions of each driver in each stage on the track in the current track scenario are different. Therefore, it is of important practical significance to collect the dynamic information corresponding to each driver's driving habits.

[0041] Step S203: Predict the steering wheel time - distribution characteristics applied to the current track scenario based on the historical dynamic information of the driver in the current track scenario.

[0042] The steering wheel time - distribution characteristics include the steering wheel gripping region and the duration of the driver in the current track scenario.

[0043] There are two ways to predict the steering wheel time distribution characteristics applied to the current track scenario, which are described as follows:

[0044] In the first case, the steering wheel time distribution characteristics applied to the current track scenario are predicted according to the model. The historical dynamic information of the driver in the current track scenario is input into the prediction model to obtain the steering wheel time distribution characteristics corresponding to the current track scenario. Among them, the prediction model is trained according to the dynamic information of the driver in multiple track scenarios and the steering wheel time distribution characteristics respectively corresponding to the dynamic information in the multiple track scenarios. The dynamic information of the driver in multiple track scenarios is feature data, and the steering wheel time distribution characteristics respectively corresponding to the dynamic information in the multiple track scenarios are label data.

[0045] In the first case, the holding area and duration of the driver when facing different curves or straight roads are predicted according to the prediction model. Due to the existence of the driving habits of racing drivers, when facing different situations, the driver uses the same handling methods as before when facing the same situation. For example, when facing a U-shaped curve, the holding area of the racing driver is basically the same. When facing an S-shaped curve, the holding area of the racing driver is basically the same. Similarly, when facing other curves or straight roads, the handling methods of the racing driver are basically unchanged, and the duration is also traceable. Based on this, the prediction model is trained according to the dynamic information in the historical race records of the racing driver, and the handling methods of the racing driver when facing different types of curves or straight roads can be obtained. The handling methods include changes in the holding area and duration. Similarly, in the track of the current track scenario, it also has basically the same structure as the track in the driver's historical race records, that is, it has curves such as S-shaped curves and U-shaped curves or straight roads, but only the curvature of the curves or the length of the straight roads are different, which only affects the duration of the holding area of the driver. When facing similar curves or straight roads, the holding area of the driver remains basically unchanged. Therefore, the holding area and duration of the steering wheel when facing different curves or straight roads in the track of the current track scenario can be predicted through the holding area and duration of the steering wheel when facing different curves or straight roads in the historical race records of the current driver of the target vehicle, so as to obtain the steering wheel time distribution characteristics corresponding to the current track scenario.

[0046] It should be noted that for different situations of a driver in a current track scenario, such as entering a straight section from a curve, entering a curve from a straight section, and entering a curve from another curve, the corresponding steering wheel gripping areas are traceable and easy to predict. However, the duration corresponding to the steering wheel gripping area requires a large amount of data training to be predicted. Specifically, since the duration starts from the time point when the driver changes the gripping area and ends at the time point of the next change of the gripping area, and the duration during this period is the above-mentioned duration, the key to the duration lies in the time node when the driver changes the gripping area. Then, according to the current driver's driving habits when operating the steering wheel, such as being accustomed to changing the steering wheel gripping area in advance to prepare for entering a curve or a straight section, or changing the steering wheel gripping area at the stage when it is necessary to change the driving trajectory of the vehicle, the corresponding duration can be predicted. Analyze and determine the time distribution characteristics of the steering wheel in a refined manner to support subsequent heating strategies and make the heating more accurate.

[0047] Optionally, different drivers correspond to different prediction models, and each driver has its own personalized prediction model.

[0048] Case 2: Predict the time distribution characteristics of the steering wheel applied to the current track scenario according to the driver's driving habits. Determine the historical gripping areas and durations of multiple track segments of the driver in the current track scenario based on the historical dynamic information of the driver in the current track scenario; in the case where the driver's driving habit is to keep the gripping area unchanged on the same type of track, determine the time distribution characteristics of the steering wheel applied to the current track scenario based on the historical gripping areas and durations of multiple track segments of the driver in the current track scenario and the track in the current track scenario.

[0049] In Case 2, if the driver's driving habit is to keep the gripping area unchanged on the same type of track. For example, when facing S-shaped curves in different races, the driver adopts the same handling method and changes the gripping areas at 3 o'clock and 9 o'clock to the gripping areas at 12 o'clock and 3 o'clock. From this, it can be inferred that in the current track scenario, when facing an S-shaped curve, the driver is very likely to continue to change the gripping area to the gripping areas at 12 o'clock and 3 o'clock. Therefore, according to the track in the current track scenario, the gripping area of the driver in each race segment and the time node of changing the gripping area can be obtained. It should be noted that the time node of changing the gripping area is related to the driver's driving habits, as well as the curvature of the curve, the length of the straight section, and the road conditions at that time. The gripping duration in the current gripping area is also related to the above factors. After actual testing, in the case where the curvature of the curve is larger and the road conditions are more complex, the time node of the driver changing the gripping area will be earlier.

[0050] Therefore, the holding duration corresponding to the holding area can be calculated according to a certain algorithm, and then the steering wheel time distribution characteristic is obtained accordingly. This embodiment can be used as a backup solution when the result obtained by the model is not accurate enough.

[0051] Step S204: Formulate a steering wheel heating strategy corresponding to the steering wheel time distribution characteristic.

[0052] The heating strategy includes the area to be heated and the heating time distribution characteristic. The heating time distribution characteristic is the heating time corresponding to different areas to be heated. Optionally, the heating time includes a pre-heating time, a heating duration, and a cooling time. The pre-heating time is the time to pre-heat the area in advance when the driver does not hold the area. The heating duration is a period of time after the driver holds the area. It should be noted that this period of time is less than the overall time when the driver holds the area. The cooling time is used to prevent the driver's palm from sweating, resulting in the steering wheel slipping out of the hand and affecting driving safety, and is generally set after the heating duration. By dividing the heating strategy in detail and considering the vast majority of unexpected situations, and including the pre-heating time, the heating duration, and the cooling time in the heating time, the intelligent cockpit domain controller can control the optimized heating function for the track mode more intelligently.

[0053] The process of formulating a steering wheel heating strategy corresponding to the steering wheel time distribution characteristic is specifically as Figure 3 shown, Figure 3 which is a schematic flowchart of a process for formulating a steering wheel heating strategy, specifically as follows:

[0054] Step S301: According to the steering wheel time distribution characteristic, split the track corresponding to the current track scenario into multiple segments of tracks.

[0055] The steering wheel time distribution characteristic includes the steering wheel holding area and duration of the driver in the current track scenario, including the change time nodes and the changed holding areas of the holding area when the driver faces various situations such as a curve turning into a straight road, a curve turning into a curve, and a straight road turning into a curve. Based on the change of the holding area, the track corresponding to the current track scenario can be split into multiple segments of tracks. On two adjacent segments of tracks, the driver's holding area is different. Each segment of the multiple segments of tracks in the current track scenario is used as the basis for mapping the steering wheel time distribution characteristic. Each segment of the track corresponds to a corresponding holding area and duration in the steering wheel time distribution characteristic. There will be certain differences in the holding area and duration corresponding to each segment of the track found in actual tests. In each race, due to the different tracks, the corresponding steering wheel time distribution characteristics and the track division are different.

[0056] Step S302: Determine the to-be-heated areas and heating durations respectively corresponding to the multi-segment race tracks.

[0057] Based on the above-mentioned multi-segment race tracks and the steering wheel time distribution characteristics, it can be determined that in any one of the multi-segment race tracks, the corresponding holding areas and durations of the driver. The duration is related to the curvature and length in the multi-segment race tracks. The greater the curvature and the longer the length in the multi-segment race tracks, the longer the duration. Therefore, set the corresponding to-be-heated areas according to the corresponding holding areas of the driver as described above, and determine the heating duration according to the above-mentioned duration. The heating duration is the time for heating this area, and does not represent the time when the driver holds this area.

[0058] Step S303: Determine the priorities of the to-be-heated areas respectively corresponding to the multi-segment race tracks according to the sequence of the multi-segment race tracks.

[0059] Determine the priorities of the to-be-heated areas respectively corresponding to the multi-segment race tracks according to the sequence of the multi-segment race tracks. Starting from the beginning of the race, the higher the priority of the to-be-heated area corresponding to the race track that the target vehicle passes through earlier. That is, the more forward the position of a certain race track in the multi-segment race tracks, the higher the priority of the corresponding to-be-heated area, thus obtaining a complete heating logic.

[0060] Step S304: Formulate a steering wheel heating strategy according to the priorities of the to-be-heated areas respectively corresponding to the multi-segment race tracks and the heating durations of the to-be-heated areas.

[0061] The steering wheel heating strategy is a method of heating a fixed area to a fixed temperature within a fixed time starting from when the driver sits in the cockpit of the target vehicle.

[0062] In Figure 3 the method shown, formulate a corresponding steering wheel heating strategy according to the steering wheel time distribution characteristics, accurately and efficiently control the temperature of the steering wheel, meet the driver's need for warming hands, and be energy-saving enough.

[0063] Step S205: Send the steering wheel heating strategy to the steering wheel sub-controller so that the steering wheel sub-controller executes the steering wheel heating strategy to implement the function of intelligent heating of the steering wheel of the target vehicle.

[0064] The intelligent cockpit domain controller sends the steering wheel heating strategy to the steering wheel sub-controller. When the steering wheel sub-controller receives the steering wheel heating strategy and executes the steering wheel heating strategy, it returns corresponding messages to the intelligent cockpit domain controller.

[0065] During the process of the steering wheel sub - controller executing the steering wheel heating strategy, the intelligent cockpit domain controller supplements the steering wheel heating strategy. In an optional implementation manner, the current hand temperature of the driver is obtained; according to the correspondence between the hand temperature and the target temperature, the target temperature corresponding to the current hand temperature of the driver is obtained; the target temperature is sent to the steering wheel sub - controller, so that the steering wheel sub - controller heats the area to be heated to the target temperature according to the steering wheel heating strategy and the target temperature. In this implementation manner, the target temperature is set. Simply speaking, the target temperature is a suitable temperature. After actual testing, the target temperature is generally 5 degrees to 12 degrees higher than the hand temperature. Precise temperature control is achieved to meet the driver's needs with the minimum energy consumption.

[0066] After the driver of the target vehicle completes the first lap of the track in the current track scenario, the steering wheel heating strategy applied in the subsequent laps is updated. In an optional implementation manner, the dynamic information of the driver of the target vehicle in the first lap of the current track scenario is recorded; according to the dynamic information of the driver in the first lap of the current track scenario, the steering wheel time distribution characteristics applied to the subsequent laps of the current track scenario are determined; according to the steering wheel time distribution characteristics applied to the subsequent laps of the current track scenario, a steering wheel heating strategy corresponding to the steering wheel time distribution characteristics is re - formulated.

[0067] Since in a track scenario, generally speaking, the same track will be run multiple times, then after the driver of the target vehicle completes the first lap in the current track scenario, the steering wheel time distribution characteristics and the steering wheel heating strategy can be updated. The first lap is the first lap that the target vehicle runs in the current track scenario. Since the steering wheel time distribution characteristics applied in the first lap are predicted and may be inaccurate, then after the first lap is completed, the steering wheel time distribution characteristics are corrected in a timely manner, and based on the dynamic information of the driver in the first lap. Finally, according to the corrected steering wheel time distribution characteristics, a steering wheel heating strategy corresponding to the steering wheel time distribution characteristics is re - formulated.

[0068] After the current race ends, the above - mentioned prediction model is optimized and updated. In an optional implementation manner, the dynamic information of the driver in any lap of the current track scenario, the predicted steering wheel time distribution characteristics, and the actual time distribution of the driver holding the steering wheel are obtained; if there is a difference between the predicted steering wheel time distribution characteristics and the actual time distribution of the driver holding the steering wheel in any lap of the race, the prediction model is trained and updated according to the dynamic information and the actual time distribution of the driver holding the steering wheel.

[0069] After the race in the current track scenario is completed, the prediction model is trained and updated according to the dynamic information of the driver in any lap of the current track scenario and the actual time distribution of the driver holding the steering wheel, further improving the accuracy of the prediction model.

[0070] In the embodiment of the present application, through the joint control of the intelligent cockpit domain controller and the steering wheel sub-controller, and the application of models and algorithms, based on the dynamic information of the current driver of the target vehicle in the historical race scenario, the possible holding areas and durations of different segments in the track of the current race are predicted, and accordingly, a corresponding heating strategy is formulated to meet the functional requirements of efficiently and accurately warming the hands following the driver's holding position in the track scenario, improving the intelligence, flexibility, and accuracy of the heating function, and reducing unnecessary performance energy consumption.

[0071] The method of the embodiment of the present application is elaborated in detail above. Below, the device of the embodiment of the present application is provided.

[0072] Please refer to Figure 4 , Figure 4 FIG. is a schematic structural diagram of a steering wheel intelligent heating device in a vehicle track mode provided by an embodiment of the present application. The steering wheel intelligent heating device 40 in the vehicle track mode can be a device in the target vehicle mentioned above. The steering wheel intelligent heating device 40 in the vehicle track mode can include a first determination unit 401, a first acquisition unit 402, a prediction unit 403, a formulation unit 404, and a first sending unit 405. Among them, the detailed descriptions of each unit are as follows.

[0073] The first determination unit 401 is configured to determine, according to the cabin environment temperature of the target vehicle, whether to turn on the track mode optimized heating function with the steering wheel sub-controller. The track mode optimized heating function refers to the function of jointly controlling the steering wheel intelligent heating of the target vehicle by the intelligent cockpit domain controller and the steering wheel sub-controller in the track scenario;

[0074] The first acquisition unit 402 is configured to, if the track mode optimized heating function is turned on, acquire the historical dynamic information of the driver of the target vehicle in the current track scenario. The dynamic information includes all the steering wheel holding positions of the driver in the current track scenario, the scenario nodes and occurrence times when the steering wheel holding positions change, and the lap speed and time consumption of the driver in the current track scenario;

[0075] The prediction unit 403 is configured to predict the steering wheel time distribution characteristics applied to the current track scenario based on the historical dynamic information of the driver in the current track scenario. The steering wheel time distribution characteristics include the steering wheel holding area and duration of the driver in the current track scenario;

[0076] A formulation unit 404, configured to formulate a steering wheel heating strategy corresponding to the steering wheel time distribution characteristic according to the steering wheel time distribution characteristic, where the heating strategy includes a to-be-heated area and a heating time distribution characteristic;

[0077] A first sending unit 405, configured to send the steering wheel heating strategy to the steering wheel sub-controller, so that the steering wheel sub-controller executes the steering wheel heating strategy, and implement the function of intelligently heating the steering wheel of the target vehicle.

[0078] The method provided by the embodiment of the present application focuses on the track scenario in the vehicle driving scenario. Many racers in racing competitions have clearly pointed out after the race that during the race, their fingers lost temperature very seriously, resulting in very stiff fingers and it was difficult to make refined operations. This also shows that in racing competitions, there is a need for steering wheel heating and it is urgent; however, due to the strict requirements for the vehicle body weight of the racing car itself, it is difficult to improve from the structure of the steering wheel or the heating equipment in the vehicle cockpit. Therefore, this method specifically performs joint control of the steering wheel heating through the intelligent cockpit domain controller and the steering wheel sub-controller, and realizes the efficient and accurate hand-warming requirement while ensuring that the weight of the equipment itself does not exceed the standard, improves the intelligence, flexibility and accuracy of the heating function, and reduces unnecessary energy consumption.

[0079] Specifically, first, determine whether the track mode optimized heating function is turned on according to the cockpit environment temperature of the target vehicle. The track mode optimized heating function is jointly controlled by the intelligent cockpit domain controller and the steering wheel sub-controller. The intelligent cockpit domain controller is the main execution body of this method, and the steering wheel sub-controller is used to specifically implement the heating function on the steering wheel side.

[0080] Secondly, if the optimized heating function of the track mode is turned on, obtain the dynamic information of the current driver of the target vehicle in previous races. Since, under normal circumstances, the driving actions of a racing driver on the same track are highly consistent, including the position nodes of steering operations when facing different curves, the steering amplitude of the steering wheel, and the gripping areas before and after steering the steering wheel, they are highly consistent on the same track, similar to the best racing route explored by the racing driver. For example, when the track is a U-shaped track, the starting state is to hold the steering wheel at the 3 o'clock and 9 o'clock positions with both hands. When reaching the first curve node, the driver turns the steering wheel to perform a steering operation and changes the gripping area when entering the curve. When there are subsequent scenario nodes where the gripping action changes, the operation is the same. Therefore, after obtaining the dynamic information, heating can be performed according to the driver's habitual gripping areas for different curves or straight sections. Specifically, the dynamic information includes all the steering wheel gripping positions of the driver in the current track scenario, as well as the scenario nodes and occurrence times when the steering wheel gripping position changes, and the lap time and elapsed time of the driver in the current track scenario. According to the dynamic information, the gripping areas and durations of the driver when facing different curves or straight sections can be analyzed, thereby obtaining the steering wheel time distribution characteristics. It should be noted that the gripping areas and durations of the driver when facing different curves or straight sections also mean that by heating the corresponding gripping areas for the corresponding durations when facing different curves or straight sections, an efficient and accurate heating function can be achieved.

[0081] Formulate a steering wheel heating strategy corresponding to the steering wheel time distribution characteristics according to the steering wheel time distribution characteristics. The heating strategy includes the area to be heated and the heating time distribution characteristics. The heating time distribution characteristics are the heating times corresponding to different areas to be heated. Optionally, the heating time includes a pre-heating time, a heating duration, and a cooling time. The pre-heating time is the time to pre-heat the area in advance when the driver has not gripped the area. The heating duration is a period of time after the driver grips the area. It should be noted that this period of time is less than the overall time when the driver grips the area. The cooling time is used to prevent the driver's palm from sweating, causing the steering wheel to slip out of the hand and affecting driving safety, and is generally set after the heating duration.

[0082] Finally, the intelligent cockpit domain controller sends the steering wheel heating strategy to the steering wheel sub-controller, and the steering wheel sub-controller heats the steering wheel according to the steering wheel heating strategy.

[0083] Through the above process, the combined control of the intelligent cockpit domain controller and the steering wheel sub-controller can meet the functional requirements of efficiently and accurately warming hands following the driver's gripping position in the track scenario, improve the intelligence, flexibility, and accuracy of the heating function, and reduce unnecessary performance energy consumption.

[0084] In a possible implementation manner, the prediction unit 403 is specifically configured to:

[0085] Input the historical dynamic information of the driver in the current track scenario into the prediction model to obtain the steering wheel time distribution characteristics corresponding to the current track scenario, where the prediction model is trained according to the dynamic information of the driver in multiple track scenarios and the steering wheel time distribution characteristics respectively corresponding to the dynamic information in the multiple track scenarios, the dynamic information of the driver in the multiple track scenarios is feature data, and the steering wheel time distribution characteristics respectively corresponding to the dynamic information in the multiple track scenarios are label data.

[0086] In this implementation manner, the prediction model is used to predict the gripping area and duration of the driver when facing different curves or straight roads. Due to the existence of the driver's driving habits, when facing a U-shaped curve, the gripping area of the racing driver is basically the same, and when facing an S-shaped curve, the gripping area of the racing driver is basically the same. Similarly, when facing other curves or straight roads, the handling method of the racing driver remains basically unchanged, and the duration is also traceable. Based on this, training the prediction model according to the dynamic information in the historical race records of the racing driver can obtain the handling methods of the racing driver when facing different types of curves or straight roads, and the handling methods include changes in the gripping area and duration. Similarly, in the track of the current track scenario, it also has basically the same structure as the track in the driver's historical race records, that is, it has curves such as S-shaped curves and U-shaped curves or straight roads, but only the curvature of the curves or the length of the straight roads affects the duration of the driver's gripping area. When facing similar curves or straight roads, the gripping area of the driver remains basically unchanged. Therefore, the steering wheel gripping area and duration when facing different curves or straight roads in the track of the current track scenario can be predicted through the dynamic information in the historical race records of the current driver of the target vehicle, so as to obtain the steering wheel time distribution characteristics corresponding to the current track scenario.

[0087] In a possible implementation manner, the prediction unit 403 is specifically configured to:

[0088] Determine the historical gripping areas and durations of multiple sections of the track of the driver in the current track scenario according to the historical dynamic information of the driver in the current track scenario;

[0089] When the driving habit of the driver is to keep the holding area unchanged on the same track, according to the historical holding areas and durations of multiple sections of the track in the current track scene of the driver, and the track in the current track scene, determine the steering wheel time distribution characteristics applied to the current track scene.

[0090] In this embodiment, predicting the steering wheel time distribution characteristics applied to the current track scene according to the driving habit of the driver. Since the driving habits of a large number of racing drivers are to keep the holding area unchanged on the same track, therefore, the holding duration corresponding to the holding area can be calculated according to a certain algorithm, and then the steering wheel time distribution characteristics are obtained accordingly. This embodiment can be used as a backup solution when the result obtained by the model is not accurate enough.

[0091] In a possible implementation manner, the formulating unit 404 is specifically configured to:

[0092] According to the steering wheel time distribution characteristics, split the track corresponding to the current track scene into multiple sections of the track, where the steering wheel holding areas corresponding to any two connected sections of the multiple sections of the track are different;

[0093] Determine the areas to be heated and the heating durations respectively corresponding to the multiple sections of the track;

[0094] According to the order of the multiple sections of the track, determine the priorities of the areas to be heated respectively corresponding to the multiple sections of the track;

[0095] Formulate a steering wheel heating strategy according to the priorities of the areas to be heated respectively corresponding to the multiple sections of the track and the heating durations of the areas to be heated.

[0096] Specifically, the steering wheel time distribution characteristics include the steering wheel holding area and duration of the driver in the current track scene, including the change time nodes of the holding area and the changed holding area when the driver faces different curves or straight roads. Based on the change of the holding area, the track corresponding to the current track scene can be split into multiple sections of the track. On two consecutive sections of the track, the driver's holding area is different. Thus, the areas to be heated and the heating durations respectively corresponding to the multiple sections of the track are determined. According to the order of the multiple sections of the track, the priorities of the areas to be heated respectively corresponding to the multiple sections of the track are determined. Starting from the beginning of the race, the higher the priority of the area to be heated corresponding to the track that the target vehicle passes through earlier.

[0097] When the above content is all determined, the areas to be heated and the durations corresponding to the track of the current track scene can be formulated according to the above content, and the areas to be heated are sorted according to the priorities of the areas to be heated to obtain a steering wheel heating strategy.

[0098] In a possible implementation, the intelligent steering wheel heating device 40 in the vehicle track mode further includes:

[0099] A second acquisition unit, configured to acquire the current hand temperature of the driver;

[0100] A third acquisition unit, configured to acquire the target temperature corresponding to the current hand temperature of the driver according to the correspondence between the hand temperature and the target temperature;

[0101] A second sending unit, configured to send the target temperature to the steering wheel sub - controller, so that the steering wheel sub - controller heats the area to be heated to the target temperature according to the steering wheel heating strategy and the target temperature.

[0102] In a possible implementation, the intelligent steering wheel heating device 40 in the vehicle track mode further includes:

[0103] A recording unit, configured to record the dynamic information of the first lap of the driver of the target vehicle in the current track scenario;

[0104] A second determination unit, configured to determine the steering wheel time distribution characteristic applied to the subsequent laps of the current track scenario according to the dynamic information of the first lap of the driver in the current track scenario;

[0105] A re - formulation unit, configured to re - formulate the steering wheel heating strategy corresponding to the steering wheel time distribution characteristic according to the steering wheel time distribution characteristic applied to the subsequent laps of the current track scenario.

[0106] In a track scenario, generally, the same track will be run multiple times. Then, after the driver of the target vehicle completes the first lap in the current track scenario, the steering wheel time distribution characteristic and the steering wheel heating strategy can be updated. The first lap is the first lap that the target vehicle runs in the current track scenario. Since the steering wheel time distribution characteristic applied in the first lap is predicted and may be inaccurate, when the first lap is completed, the steering wheel time distribution characteristic is corrected in a timely manner, and the dynamic information of the driver in the first lap is used as the basis. Finally, according to the corrected steering wheel time distribution characteristic, the steering wheel heating strategy corresponding to the steering wheel time distribution characteristic is re - formulated.

[0107] In a possible implementation, the intelligent steering wheel heating device 40 in the vehicle track mode further includes:

[0108] A fourth acquisition unit, configured to acquire the dynamic information of the driver in any lap of the race in the current track scenario, the predicted steering wheel time distribution characteristic, and the actual time distribution of the driver holding the steering wheel;

[0109] An update unit is configured to train and update a prediction model according to the dynamic information and the actual time distribution of the driver's holding of the steering wheel if there is a difference between the predicted steering wheel time distribution characteristics and the actual time distribution of the driver's holding of the steering wheel in any lap of the race.

[0110] After the race in the current track scenario is completed, the prediction model is trained and updated according to the dynamic information of the driver in any lap of the race in the current track scenario and the actual time distribution of the driver's holding of the steering wheel, further improving the accuracy of the prediction model.
