Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and in particular to a method, device, equipment, and medium for controlling the steering mode of a vehicle. Background Technology

[0002] With the continuous development of vehicle technology, the driving experience has received increasing attention in order to meet the personalized driving needs of different drivers. Currently, most vehicles offer drivers selectable driving modes and steering modes. During vehicle use, drivers can switch between driving and steering modes according to their own needs.

[0003] However, the inventors discovered that the existing technology has at least the following problems: Currently, steering mode adjustment is generally located in the third-level menu of the vehicle's central control screen. Each adjustment requires searching through the three-level menu, selecting the mode, and confirming. Drivers need to spend a considerable amount of time on the central control screen to switch steering modes, resulting in unnecessary time waste. It may even lead to situations where drivers want to adjust the steering feel but are reluctant to switch modes due to the cumbersome operation, ultimately continuing to drive without the most ideal steering feel, thus reducing user satisfaction and experience. Summary of the Invention

[0004] The purpose of this invention is to provide a method, device, equipment, and medium for controlling the steering mode of a vehicle, which can intelligently adjust the vehicle's steering mode, improve the convenience and practicality of the steering mode switching process, and thus provide users with a good driving experience.

[0005] To achieve the above objectives, embodiments of the present invention provide a method for controlling the steering mode of a vehicle, comprising:

[0006] When it is detected that the user has adjusted the driving mode of the vehicle, the current driving mode of the vehicle is obtained;

[0007] Based on the preset mapping relationship between driving mode and steering mode, determine the steering mode corresponding to the current driving mode of the vehicle.

[0008] Control the vehicle to operate according to the steering mode corresponding to the current driving mode of the vehicle.

[0009] As an improvement to the above solution, the method further includes:

[0010] When the vehicle meets the preset steering mode adjustment conditions, the steering mode corresponding to the preset steering mode adjustment conditions is determined according to the preset steering mode adjustment conditions.

[0011] Control the vehicle to operate in a steering mode corresponding to the preset steering mode adjustment conditions;

[0012] The preset steering mode adjustment conditions include: receiving a user's instruction to adjust the vehicle's steering mode;

[0013] Therefore, determining the steering mode corresponding to the preset steering mode adjustment conditions specifically involves:

[0014] Determine the steering mode corresponding to the user's instruction to adjust the steering mode of the vehicle.

[0015] As an improvement to the above solution, the preset steering mode adjustment conditions also include:

[0016] After receiving the user's instruction to adjust the steering mode of the vehicle, it is detected that the vehicle speed signal continuously meets the preset speed threshold condition within a preset time period, the steering wheel torque signal continuously meets the preset torque threshold condition within a preset time period, and the steering wheel speed signal continuously meets the preset speed threshold condition within a preset time period.

[0017] As an improvement to the above solution, after determining the steering mode corresponding to the preset steering mode adjustment conditions when the preset steering mode adjustment conditions are met, the method further includes:

[0018] Based on the current driving mode of the vehicle and the steering mode corresponding to the preset steering mode adjustment conditions, update the preset mapping relationship between the driving mode and the steering mode.

[0019] As an improvement to the above solution, the step of updating the preset mapping relationship between the driving mode and the steering mode based on the current driving mode of the vehicle and the steering mode corresponding to the preset steering mode adjustment conditions specifically involves:

[0020] Determine whether the steering mode corresponding to the preset steering mode adjustment conditions is consistent with the steering mode corresponding to the current driving mode of the vehicle.

[0021] If they are inconsistent, the steering mode corresponding to the current driving mode of the vehicle is updated according to the steering mode corresponding to the preset steering mode adjustment conditions, so as to update the mapping relationship between the preset driving mode and the steering mode.

[0022] As an improvement to the above solution, before obtaining the current driving mode of the vehicle when the user adjusts the driving mode of the vehicle, the method further includes:

[0023] Detect whether a user command has been received to activate the automatic steering mode adjustment function of the vehicle;

[0024] If so, enable the automatic steering mode adjustment function and execute: when it is detected that the user has adjusted the driving mode of the vehicle, obtain the current driving mode of the vehicle.

[0025] As an improvement to the above scheme, the steering modes include: comfort steering mode, natural steering mode, and sport steering mode.

[0026] This invention also provides a vehicle steering mode control device, comprising:

[0027] The drive mode acquisition module is used to acquire the current drive mode of the vehicle when it is detected that the user has adjusted the drive mode of the vehicle.

[0028] The steering mode determination module is used to determine the steering mode corresponding to the current driving mode of the vehicle based on a preset mapping relationship between driving mode and steering mode.

[0029] The steering module control module is used to control the vehicle to operate in a steering mode corresponding to the current driving mode of the vehicle.

[0030] This invention also provides a vehicle steering mode control device, including a processor, a memory, and a computer program stored in the memory and configured to be executed by the processor. When the processor executes the computer program, it implements the vehicle steering mode control method as described in any of the above embodiments.

[0031] This invention also provides a computer-readable storage medium comprising a stored computer program, wherein, when the computer program is executed, it controls the device containing the computer-readable storage medium to perform a vehicle steering mode control method as described in any of the preceding embodiments.

[0032] Compared with existing technologies, the present invention discloses a method, apparatus, device, and medium for controlling the steering mode of a vehicle. When a user adjusts the vehicle's drive mode, the system determines the corresponding steering mode based on the current drive mode and a preset mapping relationship between drive and steering modes, thereby controlling the vehicle to operate according to the steering mode corresponding to the current drive mode. By employing the embodiments of the present invention, the vehicle's steering mode can be automatically matched and adjusted after the user adjusts the drive mode, thus avoiding the need for the user to manually adjust the steering mode again after adjusting the drive mode, which leads to a cumbersome operation process. This improves the convenience and practicality of the steering mode switching process, providing users with a better driving experience. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] See Figure 1This is a flowchart illustrating a vehicle steering mode control method according to an embodiment of the present invention. The vehicle steering mode control method provided in this embodiment can be executed by the vehicle's domain controller, preferably the vehicle control unit (VCU).

[0042] The method for controlling the vehicle's steering mode is specifically executed through steps S11 to S13:

[0043] S11. When it is detected that the user has adjusted the driving mode of the vehicle, the current driving mode of the vehicle is obtained.

[0044] Specifically, in this embodiment of the invention, the user can adjust the driving mode of the vehicle according to their own driving needs so that the vehicle can operate in a suitable driving mode.

[0045] It should be noted that the vehicle's drive mode can be adjusted using existing methods, such as by using a physical knob or button placed in front of the armrest box to adjust the drive mode gear, or by selecting the corresponding drive mode through the central control screen (ACU). Neither of these methods affects the beneficial effects achieved by the present invention.

[0046] The driving modes include at least five modes: ECO, Normal, Sport, I-pedal, and Crazy. Understandably, the number of driving modes can be reduced or added depending on the vehicle's requirements, and this is not limited here.

[0047] When a user inputs an instruction to adjust the vehicle's driving mode according to their own needs, the vehicle controller obtains the current driving mode of the vehicle.

[0048] S12. Determine the steering mode corresponding to the current driving mode of the vehicle based on the preset mapping relationship between driving mode and steering mode.

[0049] S13. Control the vehicle to operate according to the steering mode corresponding to the current driving mode of the vehicle.

[0050] Specifically, the steering modes include: comfort steering mode, natural steering mode, and sport steering mode. Understandably, the steering drive modes can be reduced or added according to vehicle requirements, and this is not limited here.

[0051] In this embodiment of the invention, a mapping relationship between the vehicle's drive mode and steering mode is preset and stored. For example, a default mapping relationship between drive mode and steering mode is set when the vehicle leaves the factory, and this mapping relationship is stored in the internal memory of the vehicle controller in the form of a matching table.

[0052] The preset mapping relationship between driving mode and steering mode can be set according to the actual vehicle driving conditions or the user's driving preferences. As an optional implementation, when the driving mode is ECO mode, the corresponding steering mode is set to comfort steering mode; when the driving mode is Normal mode, the corresponding steering mode is set to standard steering mode; when the driving mode is Sport mode, the corresponding steering mode is set to sport steering mode; when the driving mode is I-pedal mode, the corresponding steering mode is set to standard steering mode; and when the driving mode is Crazy mode, the corresponding steering mode is set to sport steering mode.

[0053] When the vehicle controller detects that the vehicle's drive mode has been adjusted, it obtains the current drive mode of the vehicle, then finds the steering mode corresponding to the current drive mode in the matching table, and controls the vehicle to run according to the steering mode corresponding to the current drive mode of the vehicle, so as to realize the adjustment of the vehicle's steering mode.

[0054] Preferably, after determining the steering mode corresponding to the current driving mode of the vehicle, the vehicle controller will further determine whether it is inconsistent with the current vehicle's steering mode. If it is inconsistent, a control signal will be sent to control the vehicle to operate according to the steering mode corresponding to the current driving mode of the vehicle; if it is consistent, no control signal needs to be sent.

[0055] Preferably, see Figure 2 This is a schematic diagram of the automatic steering mode adjustment function of a vehicle in an embodiment of the present invention. In this embodiment, the control method is configured as an algorithm module for the automatic steering mode adjustment function and integrated into the vehicle controller.

[0056] By employing the technical means of this invention, the algorithm is integrated into the vehicle controller, separate from the vehicle ECU, which facilitates logic modification and calibration by the vehicle manufacturer. This reduces the need for frequent software modifications, integration, and verification of component ECUs by component suppliers during the development process, saving component development costs and time, and improving the vehicle manufacturer's integration and development capabilities and modification freedom.

[0057] This invention provides a method for controlling the steering mode of a vehicle. When a user adjusts the vehicle's drive mode, the method determines the corresponding steering mode based on the current drive mode and a preset mapping relationship between drive modes and steering modes. The method then controls the vehicle to operate according to the steering mode corresponding to the current drive mode. By employing this invention, the vehicle's steering mode can be automatically matched and adjusted after the user adjusts the drive mode. This avoids the need for the user to manually adjust the steering mode again after adjusting the drive mode, which would otherwise result in a cumbersome operation. This improves the convenience and practicality of switching steering modes, thus providing a better user experience.

[0058] For a preferred embodiment, see Figure 3 This is a flowchart illustrating a method for controlling a vehicle's steering mode according to an embodiment of the present invention. The present invention further implements the above embodiment, and the method for controlling the vehicle's steering mode further includes steps S14 to S15:

[0059] S14. When the vehicle meets the preset steering mode adjustment conditions, determine the steering mode corresponding to the preset steering mode adjustment conditions according to the preset steering mode adjustment conditions.

[0060] S15. Control the vehicle to operate according to the steering mode corresponding to the preset steering mode adjustment conditions.

[0061] The preset steering mode adjustment conditions include: receiving a user's instruction to adjust the vehicle's steering mode;

[0062] Therefore, determining the steering mode corresponding to the preset steering mode adjustment conditions specifically involves:

[0063] Determine the steering mode corresponding to the user's instruction to adjust the steering mode of the vehicle.

[0064] In this embodiment of the invention, steps S14 to S15 can be implemented after step S13. That is, after the vehicle's steering mode is adjusted according to the preset mapping relationship and the driving mode is adjusted, if the user is not satisfied with the feel of the current steering mode, the vehicle's steering mode can be manually adjusted.

[0065] When the vehicle controller receives a steering mode adjustment command input by the user, it determines the steering mode corresponding to the adjustment command and controls the vehicle to operate in the steering mode corresponding to the adjustment command.

[0066] Preferably, after determining the steering mode corresponding to the adjustment command, the vehicle controller will further determine whether it is inconsistent with the current vehicle's steering mode. If they are inconsistent, a control signal will be sent to control the vehicle to operate according to the steering mode corresponding to the adjustment command; if they are consistent, no control signal needs to be sent.

[0067] Specifically, the method by which the user inputs the adjustment command for the vehicle's steering mode can adopt existing technologies, such as selecting the corresponding steering mode through the menu in the central control screen and sending the corresponding adjustment command signal to the vehicle controller.

[0068] For example, see Figure 2 The user has currently selected ECO mode as the drive mode. According to the vehicle's factory settings, the default steering mode is Comfort mode. If the user is dissatisfied with the steering feel after switching to Comfort mode and wants to switch back to Standard mode, they will do so via the central control screen, sending a request to the ACU (Autopilot Unit) to switch to Standard mode. In this module, the ACU request signal is compared with the current vehicle steering mode signal. If the requested value is inconsistent with the current vehicle steering mode, the ACU request command is sent to the next level process to control the vehicle to switch to the current steering mode.

[0069] By employing the technical means of this invention, when a user is dissatisfied with the feel of the steering mode adjusted according to the matching table after switching the vehicle's drive mode, they can manually switch the steering mode, which can effectively meet the user's needs and improve the user's driving experience.

[0070] In a preferred embodiment, the preset steering mode adjustment conditions further include:

[0071] After receiving the user's instruction to adjust the steering mode of the vehicle, it is detected that the vehicle speed signal continuously meets the preset speed threshold condition within a preset time period, the steering wheel torque signal continuously meets the preset torque threshold condition within a preset time period, and the steering wheel speed signal continuously meets the preset speed threshold condition within a preset time period.

[0072] Specifically, when the vehicle controller receives a steering mode adjustment command input by the user, it determines the steering mode corresponding to the adjustment command. Then, the vehicle controller does not immediately send a control signal to adjust the vehicle's steering mode; instead, it checks and assesses the vehicle's operating status.

[0073] The vehicle controller acquires the current vehicle speed signal, steering wheel torque signal, and steering wheel speed signal. It determines whether the vehicle speed signal meets a preset speed threshold condition, the steering wheel torque signal meets a preset torque threshold condition, and the steering wheel speed signal meets a preset speed threshold condition. If all three signals meet their respective threshold conditions, the controller continuously tracks and verifies each signal to determine whether it consistently meets its corresponding threshold condition within a preset time period. If it does, it indicates that the vehicle's current operating state is safe and meets the conditions for manually adjusting the steering mode. The controller then issues a control signal to control the vehicle to operate according to the steering mode corresponding to the adjustment command.

[0074] As an optional implementation, the vehicle speed threshold condition is: the vehicle speed signal is less than 120 km / h; the torque threshold condition is: the steering wheel torque signal is less than 3 Nm; the speed threshold condition is: the steering wheel speed signal is less than 360 deg / s; and the preset duration is 60 ms.

[0075] Understandably, the above threshold conditions and preset duration settings are only a preferred implementation method. In actual applications, they can be adjusted according to the actual operating conditions of the vehicle, and no specific limitations are made here.

[0076] As an optional implementation, after determining that the vehicle speed signal, steering wheel torque signal, and steering wheel speed signal of the current vehicle all meet the corresponding threshold conditions, the vehicle controller acquires the vehicle speed signal, steering wheel torque signal, and steering wheel speed signal of the current vehicle at a preset time interval, such as 10ms, within the preset time period to determine whether the corresponding threshold conditions are continuously met.

[0077] For example, see Figure 4This is a schematic diagram of the vehicle signal judgment module in this embodiment of the invention. After acquiring the current vehicle speed signal, steering wheel torque signal, and steering wheel speed signal, the absolute values ​​of the steering wheel torque signal and speed signal are first calculated. Then, it is determined whether the vehicle speed signal is less than 120 km / h, the steering wheel torque signal is less than 3 Nm, and the steering wheel speed signal is less than 360 deg / s. When all three signals simultaneously meet the threshold conditions, the logic values ​​are further delayed and monitored in real time. By acquiring the current vehicle speed signal, steering wheel torque signal, and steering wheel speed signal at 10ms, 20ms, 30ms, 40ms, 50ms, and 60ms respectively, the system continuously monitors whether the three signals still meet the corresponding threshold conditions to ensure that each signal value remains in a condition-satisfied state within a preset time period. If it is determined that the threshold conditions are continuously met, the vehicle is controlled to operate according to the steering mode corresponding to the adjustment command. If any signal does not meet the threshold conditions, the steering mode switching request transmitted by the central control screen is interrupted, and no adjustment operation is performed on the current steering mode.

[0078] By employing the technical means of this invention, when a user's instruction to manually adjust the steering mode is received, the current operating status of the vehicle is first detected and judged. If the adjustment conditions are met, the vehicle is then controlled to operate according to the steering mode corresponding to the user's adjustment instruction. This can effectively ensure the vehicle's operational safety, reduce the probability of vehicle malfunctions, and improve the user's driving experience.

[0079] In a preferred embodiment, after step S14, the method further includes step S16:

[0080] S16. Based on the current driving mode of the vehicle and the steering mode corresponding to the preset steering mode adjustment conditions, update the preset mapping relationship between the driving mode and the steering mode.

[0081] Specifically, when a user's instruction to adjust the vehicle's steering mode is received, the steering mode corresponding to the instruction is determined. Then, the steering mode corresponding to the instruction is matched with the vehicle's current drive mode and stored in the vehicle controller's memory to update the mapping relationship.

[0082] In this embodiment of the invention, after the vehicle controller determines the steering mode corresponding to the adjustment command, regardless of whether the vehicle ultimately operates according to the steering mode corresponding to the adjustment command, the vehicle controller will update the steering mode corresponding to the adjustment command to the steering mode corresponding to the current driving mode of the vehicle in the mapping relationship and store it.

[0083] Using the technical means of this invention, when a user manually adjusts the steering mode after adjusting the driving mode because they are dissatisfied with the default mapping between the driving mode and the steering mode, the steering mode corresponding to the current driving mode in the mapping relationship can be updated and stored according to the user's adjustment command. When the user switches to the corresponding driving mode again, the steering mode automatically jumps to the mode previously selected by the user, so that the mapping relationship can better meet the user's driving needs, ensuring that the driver can continue driving with the most ideal steering feel, thereby improving user satisfaction and experience.

[0084] For example, see Figure 5 This is a schematic diagram of the vehicle update mapping relationship in an embodiment of the present invention. Five driving modes are set for the vehicle: ECO signal value is 1, Normal signal value is 2, Sport signal value is 3, I-pedal signal value is 4, and Crazy signal value is 5. Furthermore, when the user manually switches the steering mode, the central control screen ACU is in a wake-up state, with its request values ​​corresponding to Comfort signal value 1, Standard signal value 2, and Sport signal value 3. If there is no operation for a specified time, the ACU is in a sleep state, and the ACU signal value is 0.

[0085] In one scenario, the user is dissatisfied with the default steering mode and drive mode match and manually switches between them: When the user sets the vehicle drive mode to Sport mode, the vehicle controller collects data and compares the current drive mode signal value with 3. If they are the same, the drive mode is locked as Sport mode. At this time, the signal value of ACU is detected to determine whether it is in an active state (≠0). If ACU is in an active state, it is determined that the current user is dissatisfied with the steering mode corresponding to the drive mode Sport and has manually adjusted the steering mode. After the determination is completed, selection 1 in the selection module is activated, thereby updating the mapping relationship of the ACU request signal at this time and writing it into the storage module.

[0086] In another scenario, the user is satisfied with the default steering mode and drive mode matching, and there is no steering mode switching action: When the user sets the vehicle drive mode to Sport mode, the vehicle controller collects data and compares the current drive mode signal value with 3. If they are the same, the drive mode is locked as Sport mode. At this time, it is detected that the ACU has been in a dormant state. It is determined that the current user is satisfied with the steering mode corresponding to the default drive mode Sport. Selection 0 in the selection module is activated, and there is no need to update the mapping relationship.

[0087] By employing the technical means of this invention, the system determines whether the user has input a steering mode adjustment command by detecting whether the ACU is in an active state. Then, after determining that the user has input an adjustment command, the mapping table is updated. This avoids the waste of system operating space caused by the vehicle controller continuously responding to the program that updates the mapping relationship when the user has not manually adjusted the steering mode.

[0088] Preferably, step S16 is specifically executed through steps S161 to S162:

[0089] S161. Determine whether the steering mode corresponding to the preset steering mode adjustment condition is consistent with the steering mode corresponding to the current driving mode of the vehicle.

[0090] S162. If they are inconsistent, update the steering mode corresponding to the current driving mode of the vehicle according to the steering mode corresponding to the preset steering mode adjustment conditions, so as to update the mapping relationship between the preset driving mode and the steering mode.

[0091] In this embodiment of the invention, after determining that the user has input an adjustment command for the steering mode, it is further determined whether the steering mode corresponding to the adjustment command is consistent with the current steering mode of the vehicle. If they are inconsistent, the mapping relationship is updated. If they are consistent, the corresponding update mapping relationship program is not required, thus avoiding the vehicle controller from responding ineffectively to the update mapping relationship program and wasting system operating space.

[0092] As a preferred embodiment, this invention provides a method for controlling the steering mode of a vehicle, specifically including steps S21 to S24:

[0093] S21. Detect whether a user command has been received to activate the automatic steering mode adjustment function of the vehicle;

[0094] S22. If so, enable the automatic steering mode adjustment function and execute: when it is detected that the user has adjusted the driving mode of the vehicle, obtain the current driving mode of the vehicle.

[0095] S23. Determine the steering mode corresponding to the current driving mode of the vehicle based on the preset mapping relationship between driving mode and steering mode.

[0096] S24. Control the vehicle to operate according to the steering mode corresponding to the current driving mode of the vehicle.

[0097] In this embodiment of the invention, due to the diversity of user needs in practical applications, some users may prefer that the steering mode remain the same under all circumstances, without needing to switch between modes. Therefore, by setting an on / off module for the automatic steering mode adjustment function, users can choose to turn the automatic steering mode adjustment function of the vehicle on or off according to their needs.

[0098] When the user selects to enable the automatic steering mode adjustment function, the vehicle controller responds with a corresponding automatic adjustment program, detecting whether the user has adjusted the vehicle's drive mode. When the user's adjustment is detected, the controller determines the steering mode corresponding to the current drive mode based on the preset mapping relationship between drive modes and steering modes, and controls the vehicle to operate according to the steering mode corresponding to the current drive mode.

[0099] Understandably, when a user chooses to turn off the automatic steering mode adjustment function, even if the user is detected to have adjusted the vehicle's drive mode, the vehicle's steering mode will not automatically adjust accordingly.

[0100] Understandably, users can input the command to turn the vehicle's steering mode automatic adjustment function on or off via the central control screen, or they can input the command via a physical button; no specific limitation is made here.

[0101] By employing the technical means of this invention, users can select the control strategy for the steering mode according to their own driving needs, effectively meeting the diverse needs of users and improving the user's driving experience.

[0102] See Figure 6 This is a schematic diagram of a vehicle steering mode control device according to an embodiment of the present invention. The embodiment of the present invention provides a vehicle steering mode control device 30, including: a drive mode acquisition module 31, a steering mode determination module 32, and a steering module control module 33; wherein,

[0103] The drive mode acquisition module 31 is used to acquire the current drive mode of the vehicle when it detects that the user has adjusted the drive mode of the vehicle.

[0104] The steering mode determination module 32 is used to determine the steering mode corresponding to the current driving mode of the vehicle according to the preset mapping relationship between driving mode and steering mode.

[0105] The steering module control module 33 is used to control the vehicle to operate according to the steering mode corresponding to the current driving mode of the vehicle.

[0106] This invention provides a vehicle steering mode control device. When a user adjusts the vehicle's drive mode, the device determines the steering mode corresponding to the current drive mode based on a preset mapping relationship between drive modes and steering modes, and then controls the vehicle to operate according to the steering mode corresponding to the current drive mode. By employing this invention, the vehicle's steering mode can be automatically matched and adjusted after the user adjusts the drive mode, thus avoiding the need for the user to manually adjust the steering mode again to achieve the desired steering feel, which leads to a cumbersome operation process. This improves the convenience and practicality of the steering mode switching process, providing users with a better driving experience.

[0107] In a preferred embodiment, in the vehicle steering mode control device 30, the steering mode determination module 32 is further configured to:

[0108] When the vehicle meets the preset steering mode adjustment conditions, the steering mode corresponding to the preset steering mode adjustment conditions is determined according to the preset steering mode adjustment conditions.

[0109] The steering mode control module 33 is also used for:

[0110] Control the vehicle to operate in a steering mode corresponding to the preset steering mode adjustment conditions.

[0111] The preset steering mode adjustment conditions include: receiving a user's instruction to adjust the vehicle's steering mode;

[0112] Therefore, determining the steering mode corresponding to the preset steering mode adjustment conditions specifically involves:

[0113] Determine the steering mode corresponding to the user's instruction to adjust the steering mode of the vehicle.

[0114] By employing the technical means of this invention, when a user is dissatisfied with the feel of the steering mode adjusted according to the matching table after switching the vehicle's drive mode, they can manually switch the steering mode, which can effectively meet the user's needs and improve the user's driving experience.

[0115] In a preferred embodiment, the preset steering mode adjustment conditions further include:

[0116] After receiving the user's instruction to adjust the steering mode of the vehicle, it is detected that the vehicle speed signal continuously meets the preset speed threshold condition within a preset time period, the steering wheel torque signal continuously meets the preset torque threshold condition within a preset time period, and the steering wheel speed signal continuously meets the preset speed threshold condition within a preset time period.

[0117] By employing the technical means of this invention, when a user's instruction to manually adjust the steering mode is received, the current operating status of the vehicle is first detected and judged. If the adjustment conditions are met, the vehicle is then controlled to operate according to the steering mode corresponding to the user's adjustment instruction. This can effectively ensure the vehicle's operational safety, reduce the probability of vehicle malfunctions, and improve the user's driving experience.

[0118] In a preferred embodiment, the device 30 further includes a mapping relationship update module 34;

[0119] The mapping relationship update module 34 is used to update the preset mapping relationship between the driving mode and the steering mode according to the current driving mode of the vehicle and the steering mode corresponding to the preset steering mode adjustment conditions.

[0120] In a preferred embodiment, the mapping update module 34 is specifically used for:

[0121] Determine whether the steering mode corresponding to the preset steering mode adjustment conditions is consistent with the steering mode corresponding to the current driving mode of the vehicle.

[0122] If they are inconsistent, the steering mode corresponding to the current driving mode of the vehicle is updated according to the steering mode corresponding to the preset steering mode adjustment conditions, so as to update the mapping relationship between the preset driving mode and the steering mode.

[0123] Using the technical means of this invention, when a user manually adjusts the steering mode after adjusting the driving mode because they are not satisfied with the mapping relationship between the default driving mode and the steering mode, the steering mode corresponding to the current driving mode in the mapping relationship can be updated and stored according to the user's adjustment command for the steering mode. This allows the mapping relationship to better meet the user's driving needs, avoids repeated adjustments to the steering mode, and further improves the user's driving experience.

[0124] It should be noted that the vehicle steering mode control device provided in this embodiment of the invention is used to execute all the process steps of the vehicle steering mode control method of the above embodiment. The working principle and beneficial effect of the two are one-to-one, so they will not be described again.

The embodiment of the present invention provides a vehicle steering mode control device 40, including a processor 41, a memory 42, and a computer program stored in the memory and configured to be executed by the processor. When the processor executes the computer program, it implements the vehicle steering mode control method as described in the above embodiment.

[0126] This invention also provides a computer-readable storage medium, which includes a stored computer program, wherein, when the computer program is executed, it controls the device where the computer-readable storage medium is located to perform a vehicle steering mode control method as described in the above embodiments.
