The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.
[0044] The vehicle, vehicle control system, and control method of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementation methods can be combined with each other.
[0045] Under normal circumstances, when a user starts the vehicle, they turn the steering wheel to control it. The steering wheel rotates, transmitting the angle signal to the vehicle's processor. The processor, based on the received angle signal and the corresponding tire strategy adjusted by the OEM, sends steering angle signals to the tires. The tire angles then create the zigzag motion of the vehicle during movement, such as turning, steering, or lane changing. In the event of an unexpected situation where the steering wheel's steer-by-wire signal fails, the vehicle's processor can no longer receive the steering wheel's rotation angle signal and will remain in a zero state. This is considered a loss of the steer-by-wire signal, and the steer-by-wire system is malfunctioning.
[0046] See Figure 1 As shown, this application provides a vehicle control system applicable to situations where the steering wheel's drive-by-wire signal fails. The vehicle control system includes:
[0047] The data acquisition module 10 is used to acquire the rotation angle of the steering wheel operated by the driver. Optionally, the data acquisition module 10 may include a camera or a sensor. The camera may be located inside the vehicle facing the steering wheel, and is used to acquire, observe, and calculate the rotation angle of the steering wheel operated by the driver. The sensor may be an angle sensor, level, radar, etc., located on the steering wheel, and is used to acquire and calculate the operational information of the driver's steering wheel rotation angle.
[0048] The storage module 30 is used to store data relating the driver's steering wheel operation information to the tire movement information under normal steering wheel steer-by-wire signal conditions. Optionally, the storage module 30 can be the vehicle's own memory or a separate memory; this application does not impose any limitations on this.
[0049] The controller 20 is electrically connected to the acquisition module 10 and the storage module 30. In the event of a failure of the steering wheel's steerable drive signal, the controller 20 outputs a control signal corresponding to the current steering wheel movement, based on the correspondence between the steering wheel's motion information acquired by the acquisition module 10 and the data stored in the storage module 30. This ensures the reliability of steering power transmission. The steerable drive signal simulation logic of the controller 20 is such that, after the steering wheel's steerable drive signal fails, it continues to send control signals to the vehicle body to control tire movement via simulated angle signals. This allows the user to continue driving the vehicle even after the steering wheel's steerable drive signal fails, solving the vehicle control problem after the steering wheel's steerable drive signal is lost and reducing the possibility of unexpected dangerous situations. Optionally, the controller 20 can be a vehicle body processor, vehicle infotainment system, or central control system, or it can be a separate controller; this application does not impose any limitations on this.
[0050] In some optional implementations, the motion information includes the driver's steering wheel rotation angle. The tire motion information includes the tire steering angle. The correspondence data includes a table showing the relationship between the driver's steering wheel rotation angle and the actual tire steering angle when the steering wheel's steer-by-wire signal is normal; that is, a cached table storing the correspondence between the user's steering wheel rotation angle and the tire steering angle. The controller 20, in the event of a steering wheel steer-by-wire signal failure, outputs a control signal corresponding to the current steering wheel rotation angle, used to control the tire steering angle, based on the correspondence table stored in the storage module 30 and the current steering wheel rotation angle obtained by the acquisition module 10. Thus, even when the steering wheel steer-by-wire signal fails, the reliability of steering power transmission is still guaranteed, and the user is unaware of this process and will not perceive that the steering wheel has malfunctioned, thereby reducing user anxiety.
[0051] Furthermore, the controller 20 is used to output a control signal for controlling the steering angle of the tires, corresponding to the current rotation angle of the steering wheel, based on the correspondence table between the current rotation angle of the steering wheel obtained by the acquisition module 10 and the storage module 30. This may further include: the controller 20 determining the corresponding tire steering angle in the correspondence table stored in the storage module 30 based on the current rotation angle of the steering wheel obtained by the acquisition module 10, and outputting a control signal for controlling the steering of the tires based on this steering angle.
[0052] Understandably, the data stored in storage module 30 can serve as local data storage for the vehicle. Data is acquired through monitoring during daily driving; specifically, when the steering wheel's steer-by-wire signal is normal, the tire steering angle A is combined with the steering wheel rotation angle B (operated by the driver) and the actual steering wheel rotation angle C (operated by the steer-by-wire signal) to create a correspondence table between the driver's steering wheel rotation angle and the actual tire steering angle. Thus, if the steering wheel steer-by-wire signal C is lost, the driver's steering wheel rotation angle B, obtained in real-time by the in-vehicle camera and other acquisition modules 10, can be used as a tag. The controller 20 can retrieve the corresponding tire steering angle A from the local cache data stored in storage module 30 and then continue sending a control signal equivalent to the steering wheel steer-by-wire signal C, ensuring the driver can continue driving normally and reducing the possibility of unexpected dangerous situations.
[0053] See Figure 2 As shown, in some optional embodiments, the vehicle control system may further include a rescue module 40 electrically connected to the controller 20. The controller 20 is also configured to, in the event of a failure of the steering wheel's steerable signal, control the rescue module 40 to determine the nearest safe parking area, such as a rescue road or buffer zone, on the current navigation path. In this way, the nearest rescue road and buffer zone can be determined without interfering with the user's driving, maintaining the current driving state, and allowing the user to escape the current dangerous driving situation as quickly as possible without causing panic, thus solving the vehicle rescue problem after the loss of the steering wheel's steerable signal.
[0054] Furthermore, determining the nearest safe parking area on the current navigation path can include: determining the nearest safe parking area on the current navigation path that also has a buffer zone. This increases the likelihood of the vehicle safely stopping in situations such as brake or accelerator failure.
[0055] In some alternative implementations, the controller 20 is also configured to output a control signal to control the power system of the vehicle to be cut off when the vehicle enters a safe parking area, so that the vehicle can be parked safely.
[0056] It should be noted that in other examples, the rescue module 40 may not be set up. Instead, the controller 20 can be connected to the cloud. In the event of failure of the steering wheel's drive-by signal, the controller 20 can send a rescue signal to the cloud, and the cloud can send rescue operation instructions to the controller 20, such as determining the nearest safe parking area on the current navigation path and controlling the vehicle to park safely.
[0057] See Figure 3 As shown, in some optional embodiments, the vehicle control system may further include a face recognition module 50, electrically connected to the controller 20. The face recognition module 50 is used to verify the driver's facial information. After successful verification by the face recognition module 50, the controller 20, based on the steering wheel rotation angle acquired by the acquisition module 10 and the correspondence data between the current steering wheel movement information acquired by the acquisition module 10 and the data stored in the storage module 30, outputs a control signal corresponding to the current steering wheel movement information to control tire movement, thereby ensuring driving safety. Optionally, the face recognition module 50 may include a camera.
[0058] Understandably, the biggest danger of drive-by-wire steering wheels lies in the possibility of hackers hijacking the steering wheel signal. By combining a data acquisition module, a storage module, and a facial recognition module, anti-hijacking functionality can be achieved. During driving, the user's facial and movement history data is bound and retrieved with real-time data, meaning real-time facial recognition verification is performed. Through local binding and storage in the storage module, the controller will only accept and, based on verified driver steering wheel operations and the data stored in the storage module, retrieve the corresponding control signals for controlling the tire steering angle. This is verified by simulating signal channel occupancy, preventing signal hijacking. Furthermore, this function also ensures that the user can safely disengage from control even if the drive-by-wire steering wheel signal is hijacked.
[0059] This application also provides a vehicle that may include a steering system and a vehicle control system as described in the above embodiments and implementations. A controller 20 may be electrically connected to the steering system and is used to output control signals to the steering system for controlling tire movement. Vehicles employing the above-described vehicle control system can significantly improve vehicle driving safety when the linear signal of the steering wheel fails.
[0060] See Figure 4 As shown, this application embodiment also provides a vehicle control method for use when the steering wheel drive-by-wire signal fails. It should be noted that the vehicle control method of this embodiment can be implemented using the vehicle control system described in the above embodiments and implementation methods. The method includes driving operations, which include steps S1-S3:
[0061] Step S1: Store the correspondence data between the driver's steering wheel operation information and the tire movement information under normal steering wheel control signal conditions. Optionally, step S1 can be implemented by the storage module 30 of the vehicle control system described in the above embodiments and implementation methods.
[0062] Step S2: Acquire the driver's steering wheel operation information. Optionally, step S2 can be implemented using the data acquisition module 10 of the vehicle control system described in the above embodiments and implementation methods.
[0063] Step S3: Based on the acquired current steering wheel movement information and the stored correspondence data, output a control signal for controlling tire movement. This ensures the reliability of steering power transmission. The steerable wheel signal simulation logic of controller 20 is such that, when the steerable wheel signal fails, it continues to send control signals to the vehicle body to control tire movement via simulated angle signals. This allows the user to continue driving the vehicle even after the steerable wheel signal fails, solving the vehicle control problem after the loss of the steerable wheel signal and reducing the possibility of unexpected dangerous situations. Optionally, step S3 can be implemented using the controller 20 of the vehicle control system described in the above embodiments and implementation methods.
[0064] In some optional implementations, the motion information includes the driver's steering wheel rotation angle. Tire motion information includes the tire steering angle. The correspondence data includes a table showing the relationship between the driver's steering wheel rotation angle and the actual tire steering angle when the steering wheel's steer-by-wire signal is normal.
[0065] Step S3 above, which involves outputting a control signal corresponding to the current steering wheel movement based on the acquired steering wheel movement information and the stored correspondence data, can further include: outputting a control signal corresponding to the current steering wheel rotation angle based on the acquired steering wheel rotation angle and the stored correspondence table, thereby controlling the tire steering angle. In this way, even when the steering wheel's steer-by-wire signal fails, the reliability of steering power transmission is still guaranteed, and the user is unaware of this process and will not perceive that the steering wheel has malfunctioned, thus reducing the user's anxiety.
[0066] Furthermore, the step of outputting a control signal for controlling the tire steering angle corresponding to the current steering wheel rotation angle, based on the obtained current steering wheel rotation angle and the stored correspondence table, may further include:
[0067] Based on the current rotation angle of the steering wheel, determine the corresponding tire steering angle in the correspondence table;
[0068] The control signal for controlling tire steering is output at this steering angle.
[0069] Understandably, the data stored in storage module 30 can serve as local data storage for the vehicle. Data is acquired through monitoring during daily driving; specifically, when the steering wheel's steer-by-wire signal is normal, the tire steering angle A is combined with the steering wheel rotation angle B (operated by the driver) and the actual steering wheel rotation angle C (operated by the steer-by-wire signal) to create a correspondence table between the driver's steering wheel rotation angle and the actual tire steering angle. Thus, if the steering wheel steer-by-wire signal C is lost, the driver's steering wheel rotation angle B, obtained in real-time by the in-vehicle camera and other acquisition modules 10, can be used as a tag. The controller 20 can retrieve the corresponding tire steering angle A from the local cache data stored in storage module 30 and then continue sending a control signal equivalent to the steering wheel steer-by-wire signal C, ensuring the driver can continue driving normally and reducing the possibility of unexpected dangerous situations.
[0070] In some optional embodiments, the vehicle control method may further include a rescue operation, which includes determining the nearest safe parking area, such as a rescue road and buffer zone, on the current navigation path. This allows for the determination of the nearest rescue road and buffer zone without interfering with the user's driving and maintaining the current driving state, enabling the user to quickly escape the current dangerous driving situation without causing panic, thus solving the vehicle rescue problem after the loss of steering wheel drive-by-wire signals. Optionally, this rescue operation can be implemented using the rescue module 40 of the vehicle control system described in the above embodiments and implementations.
[0071] Furthermore, determining the nearest safe parking area on the current navigation path can include: determining the nearest safe parking area on the current navigation path that also has a buffer zone. This increases the likelihood of the vehicle safely stopping in situations such as brake or accelerator failure.
[0072] In some alternative implementations, once the vehicle enters a safe parking area, a control signal is output to cut off the power to the vehicle's power system, enabling the vehicle to park safely.
[0073] It should be noted that in other examples, the cloud can also send rescue operation instructions to the vehicle's body processor to determine the nearest safe parking area on the current navigation route and control the vehicle to park safely.
[0074] In some optional implementations, step S3, before outputting a control signal corresponding to the current steering wheel movement information for controlling tire movement based on the obtained steering wheel movement information and the correspondence data stored in the storage module, may further include: verifying the driver's facial information; after successful facial recognition verification, outputting a control signal corresponding to the current steering wheel movement information for controlling tire movement based on the obtained steering wheel movement information and the correspondence data stored in the storage module, thereby ensuring the safety of driving operations. Optionally, this can be implemented using the facial recognition module 50 of the vehicle control system described in the above embodiments and implementations.
[0075] Understandably, the greatest danger of drive-by-wire steering wheels lies in the possibility of hackers hijacking the steering wheel signal. The vehicle control method in this embodiment binds and retrieves the user's facial and movement history data with real-time data during driving. This means real-time facial recognition verification is performed. Through local binding and storage, the vehicle's processor will only accept and, based on verified driver input to the steering wheel, combine it with locally stored data to retrieve the corresponding control signals for controlling the tire steering angle. This is achieved by simulating signal channel occupancy, thus preventing signal hijacking. Furthermore, this function ensures that the user can safely disengage from control even if the drive-by-wire steering wheel signal is hijacked.
