[0070] Embodiment 1: In one embodiment, as Figure 2 shown, a method for intelligent control of a vehicle driving mode is provided. Taking the method applied to the Figure 1 terminal as an example, the method includes the following steps:

[0071] S1: Obtain the current position of the target vehicle.

[0072] It should be noted that the current position refers to the positioning information of the target vehicle obtained through the positioning system after the target vehicle is started. Among them, the positioning system may be GPS (Global Positioning System), BDS (BeiDou Navigation Satellite System), etc. Based on this position information, the vehicle state information corresponding to the position where the target vehicle has traveled can be obtained subsequently.

[0073] S2: Based on the current position, obtain the driving mode corresponding to the current position pre-stored in the target vehicle database to determine the first driving mode of the target vehicle.

[0074] It should be noted that the driving modes of a vehicle generally include 6 types: energy-saving mode, comfort mode, sport mode, launch mode, intelligent driving mode, and personalized mode. The intelligent driving mode described in this application automatically switches based on the energy-saving mode, comfort mode, and sport mode to meet the user's need for intelligent switching between different driving modes within a driving cycle. For example, when the battery power is high, it is recommended that the user use a driving mode with a relatively fast response (such as: sport mode), and when the battery power is low, it is recommended that the user use a driving mode with a relatively slow response (such as: energy-saving mode) to save energy and achieve a longer cruising range. Among them, from the energy-saving mode, comfort mode to the sport mode, at the same accelerator pedal opening, it means that the user's driving torque demand is getting larger and the power is getting stronger, and the corresponding battery discharge power required is greater.

[0075] In some embodiments, based on the current location, obtaining the driving mode corresponding to the current location pre-stored in the target vehicle database to determine the first driving mode of the target vehicle specifically includes:

[0076] Obtaining a target road section with a preset length corresponding to the current location, where the preset length can be set according to actual needs. Exemplarily, the target road section can be the road section corresponding to 100 meters before and after the current location;

[0077] Determining the number of times the target vehicle has traveled through the target road section, and the number of times the driving mode is used when traveling on the target road section;

[0078] In response to detecting that the number of times of travel is greater than a first preset value and the number of times of use is greater than a second preset value, determining that the driving mode is the first driving mode, where the first preset value and the second preset value can be set according to actual needs, such as both being 5 times. That is, when the target vehicle meets the above conditions, if the target vehicle is started on this road section, directly adopt this driving mode as the first driving mode;

[0079] In response to detecting that the number of times of travel is less than or equal to the first preset value, and / or the number of times of use is less than or equal to the second preset value, if a driving mode activation signal is detected, determining that the driving mode corresponding to the activation signal is the first driving mode, where the activation signal can be a signal sent by the user by clicking on the in-vehicle screen or voice summons. Exemplarily, if the user clicks on the intelligent driving mode, an intelligent driving mode activation signal is sent to the vehicle controller to enable the target vehicle to adopt this driving mode;

[0080] If no driving mode activation signal is detected, determining that the driving mode used last time before the target vehicle starts is the first driving mode.

[0081] S3: When it is detected that the first driving mode is the intelligent driving mode, obtain the status information of the target vehicle.

[0082] It should be noted that the status information of the target vehicle may include the current available battery power, demand torque-related information, the maximum battery peak discharge power value within the first preset period, and the acceleration pedal opening change rate within the second preset period. The demand torque-related information includes the change rate, the maintenance time, and the number of changes. Among them, the first preset period and the second preset period can be set according to actual needs. Exemplarily, the first preset period can be 10s, and the second preset period can be 100ms.

[0083] In some embodiments, the method for obtaining the current available battery power includes:

[0084] Obtain the mapping relationship table corresponding to the available battery power. The construction method of the mapping relationship table includes:

[0085] Obtain the first data information corresponding to the available battery power in the historical database. The first data information includes at least one of the following: battery temperature, battery power, and battery health;

[0086] Perform fitting on the first data information to obtain a first fitting value. Among them, the specific fitting method can be the least squares method, polynomial fitting, etc.;

[0087] Generate a mapping relationship between the first fitting value and the available battery power;

[0088] Based on multiple mapping relationships, construct the mapping relationship table;

[0089] Based on the mapping relationship table and the second data information corresponding to the target battery, determine the current available battery power of the target vehicle. The second data information includes: the current battery temperature, the current battery power, and the current battery health. Specifically:

[0090] Determine the second fitting value corresponding to the second data information. The calculation method of this fitting value can also be the least squares method, polynomial fitting, etc.;

[0091] When it is detected that the absolute value of the difference between the first fitting value and the second fitting value is less than a third preset value, determine the available battery power corresponding to the first fitting value as the current available battery power of the target vehicle. If there are multiple absolute values of the difference less than the third preset value, select the available battery power corresponding to the first fitting value with the minimum value among the multiple absolute values as the current available battery power of the target vehicle. Among them, the third preset value can be set according to actual needs.

[0092] In some embodiments, the method for obtaining the change rate of the required torque includes:

[0093] R C = (Tr2 – Tr1) ÷ Tr1 * 100%

[0094] Wherein, R C represents the change rate of the user's required torque value, Tr2 represents the user's required torque value in the next cycle, and Tr1 represents the user's required torque value in the current cycle.

[0095] S4: Based on the state information, determine the second driving mode of the target vehicle.

[0096] It should be noted that the second driving mode refers to when the first driving mode of the target vehicle is the intelligent driving mode, the optimal mode in the intelligent driving mode is selected through the corresponding judgment rules so that the target vehicle is in the best operating state.

[0097] In some embodiments, determining the second driving mode of the target vehicle based on the state information includes:

[0098] In response to detecting that the current available battery power is less than or equal to the first battery power threshold, determine the energy-saving mode as the initial driving mode of the target vehicle;

[0099] In response to detecting that the current available battery power is greater than the first battery power threshold and less than or equal to the second battery power threshold, determine the comfort mode as the initial driving mode of the target vehicle;

[0100] In response to detecting that the current available battery power is greater than the second battery power threshold, determine the sport mode as the initial driving mode of the target vehicle.

[0101] Wherein, the above first battery power threshold and second battery power threshold can be set according to actual needs.

[0102] After the initial driving mode is determined, the optimal driving mode is further comprehensively judged through the relevant state data during vehicle operation. Specifically:

[0103] In response to detecting that the maximum peak discharge power value of the battery is within the first preset range, or the required torque-related information meets the first preset standard, determine the energy-saving mode as the second driving mode of the target vehicle;

[0104] In response to detecting that the maximum peak discharge power value of the battery is within the second preset range, or the required torque-related information meets the second preset standard, determine the comfort mode as the second driving mode of the target vehicle;

[0105] When it is detected that the maximum peak discharge power value of the battery is within the third preset range, or the demand torque related information meets the third preset standard, it is determined that the motion mode is the second driving mode of the target vehicle.

[0106] Based on the above, the maximum peak discharge power value of the battery can refer to the maximum peak discharge power value of the battery pack within 10s. The first preset range, the second preset range, and the third preset range can be set according to actual needs. Among them, there is an overlapping part between the first preset range and the second preset range, and between the second preset range and the third preset range. Exemplarily, the first preset range is [0, 0.4Pdmax], the second preset range is [0.3Pdmax, 0.7Pdmax], and the third preset range is [0.6Pdmax, 1.0Pdmax]. When the maximum peak discharge power value of the battery satisfies two different driving modes at the same time, the final second driving mode is further determined by the preset standard to which the demand torque related information belongs. Among them, the determination method of the preset standard to which the demand torque related information belongs specifically includes:

[0107] When it is detected that the change rate A of the accelerator pedal opening is less than or equal to the fourth preset value, the change rate, the maintenance time, and the number of changes of the demand torque are obtained. Among them, the fourth preset value can be set according to actual needs, such as 10%. When the change rate of the accelerator pedal opening meets the above conditions, that is, A≤10%, continue to judge the change rate, the maintenance time, and the number of changes of the demand torque value. When it is detected that the change rate A of the accelerator pedal opening > 10%, the above conditions are not met, and the change rate, the maintenance time, and the number of changes of the demand torque value are no longer judged;

[0108] When it is detected that the change rate is less than the first change threshold, the maintenance time is greater than or equal to the first time threshold, and the number of changes is greater than or equal to the first number threshold, it is determined that the demand torque related information meets the first preset standard. Among them, the first change threshold, the first time threshold, and the first number threshold can be set according to actual needs. Exemplarily, the first change threshold can be 50%, the first time threshold can be 3s, and the first number threshold can be 2 times;

[0109] When it is detected that the change rate is greater than or equal to the first change threshold and less than the second change threshold, the maintenance time is greater than or equal to the second time threshold, and the number of changes is greater than or equal to the second number threshold, it is determined that the demand torque related information meets the second preset standard. Among them, the second change threshold, the second time threshold, and the second number threshold can be set according to actual needs. Exemplarily, the second change threshold can be 80%, the first time threshold can be 2s, and the first number threshold can be 3 times;

[0110] When it is detected that the change rate is greater than or equal to a second change threshold, the maintenance time is greater than or equal to a second time threshold, and the number of changes is greater than or equal to a third number threshold, it is determined that the required torque-related information meets a third preset standard, where the third number threshold can be set according to actual requirements. Exemplarily, the third number threshold can be 5 times.

[0111] S5: Control the target vehicle to switch from the initial driving mode to the second driving mode.

[0112] It should be noted that when the initial driving mode is inconsistent with the second driving mode, the target vehicle is controlled to switch from the initial driving mode to the second driving mode. Among them, in the intelligent driving mode, when the driving mode is automatically switched, torque gradient optimization processing is required to prevent poor ride comfort caused by torque mutation and affect the user's driving experience.

[0113] Specifically, the torque change value of the vehicle is restricted by the following formula:

[0114] N = N X-1 + min[(N0 - N X-1 ),(k * T)]

[0115] where N represents the actually output torque, N X-1 represents the torque value of the previous cycle, N0 represents the target torque value, k represents the current gradient value, and T represents the currently set cycle duration;

[0116] The current gradient value k is determined by the difference ΔN between the target torque value and the torque of the previous cycle. When ΔN is in the range of (-1000~0~1000), the range of k is (20000~0~20000).

[0117] Furthermore, when it is detected that the user clicks on a non-intelligent mode (other driving modes, such as: energy saving) on the in-vehicle screen, the vehicle control unit VCU receives the corresponding driving mode and meets the precondition (power on). At this time, the intelligent driving mode is exited and the vehicle enters the corresponding other driving mode.

[0118] In the above intelligent control method for vehicle driving modes, the method includes: obtaining the current position of the target vehicle; based on the current position, obtaining the driving mode corresponding to the current position pre-stored in the target vehicle database to determine the first driving mode of the target vehicle; in response to detecting that the first driving mode is an intelligent driving mode, obtaining the status information of the target vehicle; based on the status information, determining the second driving mode of the target vehicle; and controlling the target vehicle to switch from the initial driving mode to the second driving mode. According to the user's driving behavior habits and the vehicle status, the present application automatically switches the driving mode, reduces the number of times the user manually switches the driving mode, reduces the overall vehicle energy consumption of the driving cycle, improves the vehicle driving safety, and further enhances the user's vehicle use experience.
