[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some but not all structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0028] First of all, it should be noted that with the rapid development of vehicle technology, in order to meet the different needs of users and improve user experience, current vehicles are generally equipped with a variety of driving modes for drivers to choose from. However, when designing driving modes for new energy vehicles, the differentiation between driving modes is relatively large. Not only is there a large differentiation in the acceleration capability and acceleration response speed within the normal driving throttle range, but also the full throttle acceleration capability under different driving modes is also clearly differentiated. Although this design provides users with a variety of choices, it also causes the vehicle to lose power and responsiveness in some driving modes, affecting the user's driving experience, and may also reduce the safety of the vehicle in emergency conditions.

[0029] Based on this, the present application proposes a driving mode determination method, driving mode determination device, electronic device and computer-readable storage medium, which can automatically obtain the target driving style of the target vehicle, intelligently select a driving mode that matches the driver's driving style, and adjust the driving mode in combination with the current navigation road conditions to provide a more accurate driving mode. For details, please refer to Figure 1 , Figure 1 It is a flowchart of an exemplary embodiment of a driving mode determination method shown in the present application.

[0030] The execution subject of the driving mode determination method may be a terminal device or a server or other processing device, wherein the terminal device may be a user equipment (UE), a computer, a mobile device, a user terminal, a terminal, a cellular phone, a cordless phone, a personal digital assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, etc. The execution subject of the driving mode determination method may also be a driving mode determination device. In some possible implementations, the driving mode determination method may be implemented by a processor calling a computer-readable instruction stored in a memory.

[0031] Specifically, the driving mode determination method of this embodiment includes the following steps:

[0032] S110: In response to receiving the adaptive driving mode adjustment instruction, obtaining a target driving style and a current navigation road condition of the target vehicle.

[0033] The adaptive driving mode adjustment instruction means that the target vehicle automatically adjusts the driving mode according to the vehicle operating conditions without manual operation by the user. As an independent vehicle driving mode, the adaptive driving mode is listed alongside the sports driving mode, the easy driving mode and the economic driving mode. Users can select the corresponding driving mode through the central control screen. When the user selects the adaptive driving mode, the vehicle can automatically adjust to the corresponding driving mode in real time during driving. For example, the target vehicle can adjust the driving mode of the target vehicle in real time according to the target driving style and the current navigation road conditions, so that the vehicle can better adapt to the instant changes in driving style and navigation road conditions, and improve the energy saving and comfort of the vehicle.

[0034] The target vehicle refers to the vehicle that needs to adjust the driving mode adaptively. The framework diagram of the adaptive driving mode system of the target vehicle can be referred to Figure 2 The adaptive driving mode system includes a central control screen, a chassis controller, a vehicle controller and a motor controller; after the user selects the adaptive driving mode through the central control screen, the vehicle controller of the target vehicle receives the adaptive driving mode adjustment instruction, and determines the switching conditions of each driving mode according to the acquired target driving style and the current navigation road conditions; the operating data of the target vehicle, including steering angle and vehicle speed, is obtained from the chassis controller, and the target driving mode of the target vehicle is determined according to the operating data of the target vehicle and the switching conditions of each driving mode, and the target driving mode is fed back to the central control screen to inform the user; the vehicle controller controls the motor controller to operate according to the target driving mode, including throttle, acceleration and requested torque, and can also feed back the benefit statistics in the adaptive driving mode to the central control screen, including the accumulated energy consumption and time saved.

[0035] The target driving style reflects the driver's personal habits, preferences, etc. For example, the target driving style can be determined based on the operating data of the target vehicle, such as the accelerator pedal change rate, acceleration, etc. The driving style generally includes an aggressive driving style, a normal driving style, and a gentle driving style. The aggressive driving style is characterized by rapid acceleration, sudden braking, frequent lane changes, high-speed driving, etc. The normal driving style is characterized by smooth acceleration, predicting road conditions in advance, maintaining an appropriate distance between vehicles, and following speed limit regulations. The gentle driving style is characterized by focusing on fuel economy and environmental protection, and driving by lightly pressing the accelerator and avoiding sudden acceleration and sudden braking. Therefore, the target driving style of the target vehicle can be determined by the operating data of the target vehicle, such as the speed, acceleration, and accelerator pedal change rate.

[0036] The current navigation road condition may be the road condition of the road on which the vehicle is currently traveling. For example, when the target vehicle turns on navigation, the road condition of the road on which the vehicle is currently traveling may be determined through navigation. The current navigation road condition may be smooth, slow, or congested. In the face of different navigation road conditions, the switching conditions of each driving mode may be appropriately adjusted to prevent traffic accidents while improving the energy efficiency of the vehicle.

[0037] S120: adjusting initial switching conditions between driving modes according to the target driving style of the target vehicle and the current navigation road condition to obtain adjusted switching conditions.

[0038] The initial switching condition may be the original switching condition of each driving mode, or the switching condition of each driving mode after the last adjustment. In the adaptive driving mode, the driving mode determination device needs to adjust the initial switching conditions between the driving modes in real time to obtain the adjusted switching conditions. In order to improve the driving stability of the vehicle, the initial switching conditions between the driving modes may be adjusted after a preset time period to obtain the adjusted switching conditions.

[0039] As an example, the driving mode determination device can adjust the initial switching conditions between the driving modes according to the target driving style of the target vehicle. Exemplarily, the switching conditions between the driving modes are different according to the target driving style. For example, the switching conditions for the aggressive driving style to enter the sports driving mode are lower than the switching conditions for the soft driving style to enter the sports driving mode, and the switching conditions for the aggressive driving style to enter the economic driving mode are higher than the switching conditions for the soft driving style to enter the economic driving mode, etc.

[0040] As another example, the driving mode determination device may also adjust the initial switching conditions between the driving modes according to the current navigation road condition of the target vehicle. For example, the current navigation road condition is different, and the switching conditions between the driving modes are also different accordingly. For example, if the current navigation road condition shows congestion and the congestion distance is greater than the preset congestion distance, the switching condition for entering the sports driving mode is higher than the switching condition for entering the soft driving style.

[0041] As another example, the driving mode determination device may also adjust the initial switching conditions between the driving modes according to the target driving style of the target vehicle and the current navigation road condition. Exemplarily, the initial switching conditions between the driving modes may be adjusted by combining the target driving style and the current navigation road condition in a weighted combination manner. In other embodiments, the initial switching conditions may be adjusted first by the target driving style, and then corrected by the current navigation road condition to obtain the adjusted switching conditions for each driving mode.

[0042] As another example, the driving mode determination device can also adjust the initial switching conditions between the driving modes according to the target driving style of the target vehicle, the current navigation road conditions and the current driving mode to obtain the adjusted switching conditions. For example, in addition to considering the target driving style and the current navigation road conditions, the current driving mode is also a factor to be considered, and the initial switching conditions of each driving mode can be adjusted according to the degree of difference between the current driving mode and each driving mode. For example, the switching condition from the economic driving mode to the sports driving mode can be higher than that from the easy driving mode to the sports driving mode.

[0043] S130: Matching the target vehicle's operating data with each adjusted switching condition to obtain a target switching condition.

[0044] The operation data may be various information generated by the target vehicle during operation. For example, the operation data may include, but are not limited to, the speed, acceleration, accelerator pedal opening, accelerator pedal change rate, driving mode, etc. of the target vehicle. The switching condition may include a threshold value of each operation data. The operation data of the target vehicle is matched with the switching conditions adjusted for each driving mode to obtain a matching target switching condition.

[0045] The target switching condition refers to the switching condition satisfied by the target vehicle's operating data. Exemplarily, the target vehicle's operating data is matched with each adjusted switching condition to obtain a matching target switching condition. For example, the switching condition after the sports driving mode is adjusted is: the acceleration reaches the first preset acceleration threshold, the throttle pedal opening reaches the first preset throttle pedal opening threshold, and the throttle pedal change rate reaches the first preset throttle pedal change rate threshold; when the throttle pedal opening of the target vehicle is greater than the first preset throttle pedal opening threshold, the throttle pedal change rate is greater than the first preset throttle pedal change rate threshold, and the acceleration is greater than the first preset acceleration threshold, it means that the target vehicle's operating data meets the switching condition of the sports driving mode, and the switching condition is determined as the target switching condition.

[0046] S140: Switching the current driving mode according to the target switching condition to obtain the target driving mode.

[0047] After determining the target switching condition of the target vehicle, the driving mode determination device obtains the driving mode corresponding to the target switching condition and uses it as the target driving mode; then switches the current driving mode of the target vehicle to the target driving mode.

[0048] It can be seen that the driving mode determination method of the embodiment of the present application obtains the target driving style and current navigation road condition of the target vehicle in response to receiving the adaptive driving mode adjustment instruction; adjusts the initial switching conditions between the driving modes according to the target driving style and current navigation road condition of the target vehicle to obtain the adjusted switching conditions; matches the operating data of the target vehicle with each adjusted switching condition to obtain the target switching condition; switches the current driving mode according to the target switching condition to obtain the target driving mode. Thus, the initial switching conditions of the driving mode are adjusted in combination with the target driving style and the current navigation road condition, which not only meets the needs of users, but also takes into account the influence of the current navigation road condition, so that the determined target driving mode is more in line with the current driving condition.

[0049] Based on the above embodiments, the embodiments of the present application adopt Figure 3 The flowchart details how to adjust the initial switching conditions between driving modes. Figure 3 , Figure 3 yes Figure 1 The flowchart of an exemplary embodiment of step S120 in the driving mode determination method is shown. Specifically, step S120 adjusts the initial switching conditions between the driving modes according to the target driving style of the target vehicle and the current navigation road conditions, and the process of obtaining the adjusted switching conditions specifically includes the following steps:

[0050] S310: performing a first adjustment process on the initial switching conditions of each driving mode according to the target driving style of the target vehicle, and obtaining the initial switching conditions of each driving mode after the first adjustment process.

[0051] The target driving style reflects the user's personal habits and preferences, so adjusting the initial switching conditions of each driving mode based on the target driving style of the target vehicle can better meet the user experience. Exemplarily, the target driving style can be determined by the driving style of the target vehicle in the historical time period. Specifically, the number of driving styles of the target vehicle in the historical time period is counted; in response to the number of driving styles being greater than the preset number threshold, the corresponding driving style is determined as the target driving style of the target vehicle. Thus, the target driving style is determined based on the historical driving style of the target vehicle, which can ensure the stability and objectivity of the target driving style. In other embodiments, the target driving style can also be obtained by counting the running data of the target vehicle in the current driving segment, and the current driving segment can be the process of the speed of the target vehicle from 0 to the current time point, and the average value and extreme value of each data in the running data of the target vehicle in the current driving segment are counted; the target driving style of the target vehicle is determined according to the average value and extreme value of each data in the running data of the target vehicle in the current driving segment.

[0052] Among them, the driving mode determination device can establish a table of the number of each driving style, and update the table in real time so that the number of each driving style can be quickly obtained. The driving style number table will not be cleared after the vehicle is powered off. Exemplarily, the driving style can be obtained once every preset time period, and then the corresponding driving style in the driving style number table is added by 1. Then the driving mode determination device can select a driving style whose number of driving styles is greater than a preset number threshold, and use it as the target driving style of the target vehicle. In some embodiments, each driving style is sorted from large to small according to the number, and the top N driving styles in the sorting can be selected as the target driving style of the target vehicle, where N can be 1, 2, etc. When N is at least two, each target driving style can be processed in a weighted manner.

[0053] In order to improve the reliability of the target driving style, it is possible to determine whether the driving style of the target vehicle needs to be switched to the target driving style for each historical sub-time period through the vehicle speed, accelerator pedal and acceleration. Exemplarily, two conditions may be included, one condition is that the difference between the time point of the last switching of the driving style and the current time point is greater than the preset difference, the speed of the target vehicle is within the preset range, the accelerator pedal signal is valid, and the accelerator pedal signal is greater than the preset accelerator pedal value; the other condition is that the difference between the time point of the last switching of the driving style and the current time point is greater than the preset difference, the speed of the target vehicle is within the preset range, the acceleration signal is valid and greater than the preset acceleration value; when both conditions are not met, the driving style of the target vehicle is not changed, and the driving style obtained by the last switch is maintained.

[0054] The driving mode determination device may also divide the historical time period into at least one historical sub-time period, obtain the operating data of the target vehicle in each historical sub-time period; determine the driving style of the target vehicle in each historical sub-time period according to the operating data of the target vehicle in each historical sub-time period; count the driving styles of each historical sub-time period, and obtain the number of each driving style of the target vehicle in the historical time period. In other embodiments, the driving mode determination device may also perform weighted processing on the driving style of the target vehicle in each historical sub-time period according to time from morning to night, and the weight of the historical sub-time period closer to the current time point is higher; then perform statistical processing on each weighted driving style to obtain the score of each driving style; and determine the target driving style of the target vehicle according to the score of each driving style. This can solve the problem that the user of the vehicle changes but the driving style cannot be updated in time.

[0055] Among them, the historical sub-time period can be a vehicle travel time slice. The driving mode determination device obtains the operating data of the target vehicle in each historical sub-time period, including the average accelerator pedal opening, average acceleration, accelerator pedal change rate, average vehicle speed, etc. of the target vehicle. Exemplarily, the driving mode determination device divides different vehicle speed levels, and sets threshold conditions for different driving styles at different vehicle speed levels, including but not limited to accelerator pedal change rate threshold, acceleration threshold, pedal depth threshold, accelerator pedal fast step frequency threshold, etc.; the driving style of each historical sub-time period is determined by the driving style threshold conditions at different vehicle speed levels. For details, please refer to Figure 4, for the style recognition of each historical sub-time period, for the same driving mode and at the same vehicle speed level, the threshold conditions corresponding to the gentle driving style, the ordinary driving style, and the aggressive driving style are increased in sequence. The first preset threshold condition can be set as the threshold condition for the gentle driving style, the second preset threshold condition can be set as the threshold condition for the ordinary driving style, and the third preset threshold condition can be set as the threshold condition for the aggressive driving style. Among them, the first preset threshold condition is lower than the second preset threshold condition, and the second preset threshold condition is lower than the third preset threshold condition. Specifically, the accelerator pedal change rate threshold, acceleration threshold, pedal depth threshold, accelerator pedal fast pressing frequency threshold, etc. in the first preset threshold condition are all lower than the accelerator pedal change rate threshold, acceleration threshold, pedal depth threshold, accelerator pedal fast pressing frequency threshold, etc. in the second preset threshold condition, and the accelerator pedal change rate threshold, acceleration threshold, pedal depth threshold, accelerator pedal fast pressing frequency threshold, etc. in the second preset threshold condition are all lower than the accelerator pedal change rate threshold, acceleration threshold, pedal depth threshold, accelerator pedal fast pressing frequency threshold, etc. in the third preset threshold condition. As an example, according to the order of soft type, normal type and aggressive type, the average accelerator pedal depth, average acceleration, pedaling speed and pedal quick pressing frequency increase in sequence. The soft type has a small average accelerator pedal depth, a small average acceleration, a slow pedaling speed and a low pedal quick pressing frequency. The aggressive type has a large average accelerator pedal depth, a large average acceleration, a fast pedaling speed and a high pedal quick pressing frequency.

[0056] After determining the target driving style of the target vehicle, the driving mode determination device performs a first adjustment process on the initial switching conditions of each driving mode according to the target driving style, and obtains the initial switching conditions of each driving mode after the first adjustment process. Exemplarily, for the sports driving mode, the initial switching condition of the aggressive driving style is adjusted to the first preset initial condition, the initial switching condition of the ordinary driving style is adjusted to the second preset initial condition, and the initial switching condition of the soft driving style is adjusted to the third preset initial condition, the first preset initial condition is lower than the second preset initial condition, and the second preset initial condition is lower than the third preset initial condition; for the economic driving mode, the initial switching condition of the aggressive driving style is adjusted to the fourth preset initial condition, the initial switching condition of the ordinary driving style is adjusted to the fifth preset initial condition, and the initial switching condition of the soft driving style is adjusted to the sixth preset initial condition, the fourth preset initial condition is higher than the fifth preset initial condition, and the fifth preset initial condition is higher than the sixth preset initial condition. In this way, the switching conditions of each driving mode are more in line with the user's driving style.

[0057] Among them, in actual applications, users with a gentle driving style prefer the economic driving mode more than users with a normal driving style or an aggressive driving style, and users with an aggressive driving style prefer the sports driving mode more than users with a normal driving style or a gentle driving style.

[0058] Therefore, for the sports driving mode, the first preset initial condition of the aggressive driving style is the lowest, that is, it is easier to enter the sports driving mode, and the third preset initial condition of the soft driving style is the highest, and it is the least likely to enter the sports driving mode. For example, for the aggressive driving style, it can enter the sports driving mode by lightly pressing the pedal, while for the soft driving style, it needs to deeply press the pedal to enter the sports driving mode. This is only an example, and multiple factors need to be considered in actual applications.

[0059] For the economic driving mode, the first preset initial condition of the gentle driving style is the lowest, that is, it is easier to enter the economic driving mode, and the third preset initial condition of the aggressive driving style is the highest, and it is least likely to enter the economic driving mode. For example, for the gentle driving style, the pedal depth does not need to be very shallow to enter the economic driving mode, while for the aggressive driving style, the pedal depth needs to be very shallow to enter the economic driving mode. This is only an example, and multiple factors need to be considered in actual applications.

[0060] The normal driving style is between the gentle driving style and the aggressive driving style, and there are differences between the gentle driving style and the aggressive driving style.

[0061] In other embodiments, for the easy driving mode, the initial switching condition of the aggressive driving style can be adjusted to the seventh preset initial condition, the initial switching condition of the normal driving style can be adjusted to the eighth preset initial condition, and the initial switching condition of the soft driving style can be adjusted to the ninth preset initial condition, the seventh preset initial condition is higher than the eighth preset initial condition, and the eighth preset initial condition is higher than the ninth preset initial condition. In this way, the difficulty of the aggressive driving style, the normal driving style, and the soft driving style entering the easy driving mode is reduced in sequence.

[0062] S320: Performing a second adjustment process on the initial switching conditions of each driving mode after the first adjustment process according to the current navigation road condition to obtain the adjusted switching conditions of each driving mode.

[0063] The current navigation road condition can reflect whether the current driving road can meet the driving conditions of the corresponding driving mode. Therefore, it is necessary not only to meet the user's needs, but also to consider the current actual driving conditions, and to modify the initial switching conditions of each driving mode after the first adjustment according to different driving conditions to ensure the adaptability of the switching conditions of each driving mode. Specifically, in response to the current navigation road condition indicating that the congestion distance is greater than the preset congestion distance, the initial switching conditions of the economic driving mode after the first adjustment are lowered to obtain the switching conditions after the adjustment of the economic driving mode; in response to the current navigation road condition indicating that the unblocked distance is greater than the preset unblocked distance, the initial switching conditions of the sports driving mode after the first adjustment are lowered to obtain the switching conditions after the sports driving mode; in response to the current navigation road condition indicating that the slow-moving distance is greater than the preset slow-moving distance, the initial switching conditions of the sports driving mode and the economic driving mode after the first adjustment are respectively increased to obtain the switching conditions after the sports driving mode and the switching conditions after the adjustment of the economic driving mode.

[0064] It is understandable that when the current navigation road condition indicates congestion and the congestion distance is greater than the preset congestion distance, the vehicle stops frequently and the vehicle speed is relatively slow, so the initial switching condition after the first adjustment process of the economic driving mode can be lowered, so that the target vehicle can more easily enter the economic driving mode. Exemplarily, the initial switching condition for switching from other driving modes to the economic driving mode can be a series of operating data such as the accelerator pedal opening is less than the second preset accelerator pedal opening threshold, the vehicle speed is effective and greater than the second preset vehicle speed threshold, and the acceleration is less than the second preset acceleration threshold. Therefore, a correction coefficient greater than 1 can be output to correct the first preset accelerator pedal threshold, the first preset acceleration threshold and other conditions in the initial switching condition of the economic driving mode after the first adjustment process, thereby reducing the entry conditions of the economic driving mode.

[0065] When the current navigation road condition indicates smooth traffic and the smooth traffic distance is greater than the preset smooth traffic distance, the initial switching conditions of the sports driving mode after the first adjustment process can be appropriately lowered, so that the target vehicle can more easily enter the sports driving mode. Exemplarily, the switching conditions for other driving modes to enter the sports driving mode can be: the accelerator pedal opening is greater than the first preset accelerator pedal opening threshold, the accelerator pedal change rate is greater than the first preset accelerator pedal change rate threshold, the acceleration is greater than the first preset acceleration threshold and other vehicle operation data. Therefore, a correction coefficient less than 1 can be output to correct the second preset accelerator pedal threshold, the second preset acceleration threshold and other conditions in the initial switching conditions of the sports driving mode after the first adjustment process, thereby reducing the entry conditions of the sports driving mode. Thereby improving the lightness and power responsiveness of driving on smooth roads.

[0066] When the current navigation road condition indicates slow driving and the slow driving distance is greater than the preset slow driving distance, slow driving indicates a road section where the vehicle stops less frequently but the acceleration conditions are not high. At this time, the initial switching conditions of each driving mode after the first adjustment process can be appropriately increased so that the target vehicle can stably maintain the current driving mode to ensure the stability and controllability of the slow driving condition. Specifically, for the economic driving mode, a correction coefficient less than 1 can be output to correct the initial switching conditions of the economic driving mode after the first adjustment process, and for the sports driving mode, a correction coefficient greater than 1 can be output to correct the initial switching conditions of the sports driving mode after the first adjustment process.

[0067] In addition, if the target vehicle is provided with other driving modes, such as an easy driving mode, a mountain driving mode, etc., adaptive adjustments can be made through the above method.

[0068] In other embodiments, the driving mode determination device can also directly modify the initial switching conditions of each driving mode of the target vehicle according to the current navigation road conditions. The modification method can refer to the above process of modifying the initial switching conditions of each driving mode after the first adjustment based on the current navigation road conditions.

[0069] For ease of understanding, Figure 5 The schematic diagram of an application scenario of driving mode switching shown in the figure further illustrates:

[0070] First, the driving mode has the lowest power intensity, which is the economic driving mode, and the highest power intensity, which is the sports driving mode; the switching conditions for gradually jumping from the economic driving mode to the sports driving mode may include driver behavior, current navigation road conditions and vehicle behavior, wherein the driver behavior includes deep pedaling and fast pedaling, the current navigation road condition is a smooth road, and the vehicle behavior includes a larger accelerator pedal opening, an increase in required torque, an increase in the accelerator pedal change rate, and a rapid increase in vehicle speed; the switching conditions for gradually jumping from the sports driving mode to the sports driving mode may include driver behavior, current navigation road conditions and vehicle behavior, wherein the driver behavior includes shallow pedaling and slow pedaling, the current navigation road condition is a congested road, and the vehicle behavior includes an unchanged or reduced accelerator pedal opening, a decrease in required torque, and a stable or decreasing vehicle speed. In addition, in order to ensure driving safety, the situation of prohibiting the switching of driving modes can be set. When the safety function of the target vehicle is triggered, the auxiliary driving function is triggered, or the road encounters a large slope or a large turn, the target vehicle needs to maintain the current driving mode and not switch the driving mode.

[0071] Further, in order to improve the energy saving of the target vehicle, the energy recovery level of the target vehicle can also be adjusted according to the target driving mode and the current navigation road conditions, so as to improve the energy utilization rate of the vehicle and extend the cruising range. The energy recovery of the target vehicle can be to convert the kinetic energy generated during the deceleration or braking of the vehicle into electrical energy and store it in the battery for subsequent use. For different driving modes, the energy recovery level of the target vehicle is different. For example, in the economic driving mode, the vehicle will maximize energy recovery, while in the sports driving mode, the energy recovery level of the vehicle will be reduced to provide a more direct driving experience. Therefore, after the target driving mode is determined for the target vehicle, the initial energy recovery level can be determined according to the target driving mode of the target vehicle. For example, the first preset energy recovery level can be determined as the initial energy recovery level of the economic driving mode, and the second preset energy recovery level can be determined as the initial energy recovery level of the easy driving mode and the sports driving mode, wherein the first preset energy recovery level is higher than the second preset energy recovery level. After that, the initial energy recovery level can also be corrected according to the current navigation road conditions to obtain the target energy recovery level of the target vehicle.

[0072] Exemplarily, when the current navigation road condition represents congestion, the vehicle stops frequently under congested conditions, and the energy recovery level needs to be enhanced to produce a driving experience similar to that of a single pedal, thereby reducing the frequency of back-and-forth operations between the accelerator pedal and the brake pedal, and improving driving experience and economy. Specifically, a correction coefficient greater than 1 can be output to correct the second preset energy recovery level and increase the energy recovery intensity of the second preset energy recovery level. When the current navigation road condition represents smooth traffic, the vehicle deceleration demand is less under smooth traffic conditions, and the energy recovery level needs to be reduced to improve the lightness of driving. Specifically, a correction coefficient less than 1 can be output to correct the first preset energy recovery level and the second preset energy recovery level and reduce the energy recovery intensity of the first preset energy recovery level and the second preset energy recovery level.

[0073] In order to elaborate on the driving mode determination method used in this application, Figure 6 The flowchart shown further illustrates it, and the details are as follows:

[0074] The user turns on the adaptive driving mode. The user can select the adaptive driving mode through the central control screen of the target vehicle. Then the central control screen displays the selection of the adaptive driving mode, and the instrument panel displays the current driving mode of the target vehicle. Generally, the adaptive driving mode will initialize the vehicle's driving mode to the easy driving mode.

[0075] Then, the driving mode determination device obtains the driving style of the target vehicle in the historical time period; determines the target driving style of the target vehicle according to the driving style in the historical time period; performs a first adjustment process on the initial switching conditions of each driving mode based on the target driving style, and obtains the initial switching conditions after the first adjustment process;

[0076] The driving mode determination device then determines whether the target vehicle has navigation turned on. If not, the target driving mode is determined directly according to the initial switching condition after the first adjustment of the target driving style without using the current navigation road condition for correction; if turned on, the controller reads the current navigation road condition; and processes the current navigation road condition to obtain congestion information, which includes whether the current road is congested and the congestion distance, etc.; then, based on the congestion information of the current navigation road condition, the initial switching condition of each driving mode after the first adjustment is corrected to obtain the target switching condition of each driving mode;

[0077] Then, the target driving mode of the target vehicle is determined based on the operating data of the target vehicle and the target switching conditions of each driving mode. The operating data of the target vehicle is determined based on the actual driving demand of the current target vehicle, that is, the actual accelerator pedal opening, acceleration, vehicle speed, etc. of the vehicle.

[0078] At the same time, the target driving mode of the target vehicle and the current navigation road conditions are also associated with the energy recovery level and steering assist type of the target vehicle. When the user selects the adaptive driving mode, the central control screen will update and display the current driving mode of the target vehicle in real time, and compare the energy saving and acceleration responsiveness benefits based on the fixed driving mode and the adaptive driving mode, and display the cumulative energy saving and time.

[0079] It should be noted that the overall requirements for driving mode switching include: driving mode switching should be associated with the current driver's driving torque, acceleration and other requirements; switching must be accompanied by transition logic to ensure smoothness; when switching the energy recovery level associated with the driving mode, a transition processing strategy is also required to ensure that there will be no multi-stage deceleration feeling during coasting deceleration; the driving mode switching conditions set by drivers with different driving styles must have a certain degree of distinction to prevent too frequent switching of different modes. For example, the switching condition for switching from an aggressive driving style to a sports driving mode is the highest, the switching condition for switching from an ordinary driving style to a sports driving mode is medium, and the switching condition for switching from a gentle driving style to a sports driving mode is the lowest.

[0080] As an example, see Figure 7In the adaptive driving mode, if the target vehicle's driving environment is a city, the target vehicle will mainly maintain the easy driving mode; when encountering a congested section and the congestion distance is greater than the preset distance, the target vehicle will switch from the easy driving mode to the economic driving mode after detecting that the target vehicle has been driving gently for a certain period of time (for example, 600 seconds); when the congested section is removed and the vehicle is driving on an elevated road, the driver will slightly step on the accelerator pedal, and the target vehicle will switch from the economic driving mode to the easy driving mode; if the driver steps on the accelerator pedal quickly, the target vehicle will switch from the easy driving mode to the sports driving mode. If the journey remains smooth and the driver continues to step on the accelerator to accelerate and overtake, the target vehicle will remain in the sports driving mode; until it returns to the city road and recognizes that the non-intense driving time reaches the preset time, it will switch from the sports driving mode to the easy driving mode. In this way, the driver's behavior is detected in real time, and the real-time driving needs are judged. The driving mode is intelligently switched based on the driving needs to improve the driving experience.

[0081] See also Figure 8 , Figure 8 8 is a schematic diagram of an exemplary embodiment of a driving mode determination device shown in the present application. The driving mode determination device 800 includes an acquisition module 810, an adjustment module 820, a matching module 830 and a switching module 840. The acquisition module 810 is used to obtain the target driving style and current navigation road conditions of the target vehicle in response to receiving an adaptive driving mode adjustment instruction; the adjustment module 820 is used to adjust the initial switching conditions between the driving modes according to the target driving style and current navigation road conditions of the target vehicle to obtain the adjusted switching conditions; the matching module 830 is used to match the operating data of the target vehicle with the adjusted switching conditions to obtain the target switching conditions; the switching module 840 is used to switch the current driving mode according to the target switching conditions to obtain the target driving mode.

[0082] In the above scheme, in response to receiving the adaptive driving mode adjustment instruction, the driving mode determination device obtains the target driving style and current navigation road conditions of the target vehicle; adjusts the initial switching conditions between the driving modes according to the target driving style and current navigation road conditions of the target vehicle to obtain the adjusted switching conditions; matches the operating data of the target vehicle with the adjusted switching conditions to obtain the target switching conditions; switches the current driving mode according to the target switching conditions to obtain the target driving mode. Thus, the initial switching conditions of the driving mode are adjusted in combination with the target driving style and the current navigation road conditions, which not only meets the needs of users, but also takes into account the influence of the current navigation road conditions, so that the determined target driving mode is more in line with the current driving conditions.
