Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

Fig. 1 is a structural diagram of a steering wheel control system according to an embodiment of the present disclosure, and as shown in fig. 1, the steering wheel control system includes: a controller 101, a system switch 102, an instrumentation system 103, an information system 104, a steering system 105, and a central gateway 106.

The controller 101 is a main control unit of the steering wheel control system, and is configured to generate a control signal. Optionally, the control signal comprises a target steering angle signal, i.e. a difference between the steering wheel angle and an angle threshold. Optionally, the controller 101 is a newly added controller 101 in the automobile, or an existing controller of the automobile integrated with the automatic steering wheel returning function is adopted as the controller 101, that is, software corresponding to the automatic steering wheel returning function is integrated in the existing controller of the automobile.

The system switch 102 is used to turn on or off the auto-return function of the steering wheel control system, and optionally, the system switch 102 may be a hardware switch or a software switch.

The instrumentation system 103 may include a Human Machine Interface (HMI) display module for sending prompts to the driver, either by text or by voice, which may include confirmation options, reasons for interruption, etc. Alternatively, the instrumentation system 103 may be mounted on a computer host or a high-density Digital Video Disc (DVD). The driver may activate the stall steering wheel recovery function or the non-stall steering wheel recovery function in the meter system 103. Alternatively, each time the steering wheel control system is turned on, the most recently enabled function is enabled by default. For example, if the key-off steering wheel return function is activated before the current turning-off of the steering wheel control system, the key-off steering wheel return function is activated by default when the steering wheel control system is turned on next time. The steering wheel control system is turned off, including both manual and automatic turning off of the system by the driver.

Meanwhile, the driver may also perform personalized settings on the steering wheel control system on the meter system 103, such as an angle threshold for steering wheel turning, a waiting time for waiting for the door to be locked, and the like.

The information system 104 is used to provide status information of the steering wheel, such as the turning angle of the steering wheel, as well as wheel speed, gear information, ignition information, door lock information, and the like. For example, the information system 104 may include a Passive Entry Passive Start (PEPS) system for providing ignition information, i.e., whether the vehicle is in an off state or a non-off state; an Electronic Stability Program (ESP) system for providing vehicle speed information, wheel speeds, etc.; a Body Control Module (BCM) for providing door lock information; a Transmission Control Unit (TCU) is used to provide gear information; the rotation angle sensor is used for providing a steering wheel rotation angle.

The steering system 105 is configured to control the steering wheel to return to normal based on a control signal generated by the controller 101. Alternatively, the Steering system 105 may include an Electric Power Steering (EPS). Illustratively, the EPS may provide steering angles of the steering wheel in addition to controlling steering wheel alignment based on the control signal. Therefore, when the steering system 105 is an EPS, the steering wheel angle can be directly provided by the EPS without providing an angle sensor in the information system 104.

A Central Gateway (CGW) 106 is used for signal forwarding and network management wake-up. Here, the signal forwarding means, for example, forwarding a control signal generated by the controller 101 to the steering system 105; the network management awakening refers to keeping a network connection state so as to provide information intercommunication among various parts in the system.

Optionally, each part of the system may communicate with each other through a Controller Area Network (CAN), or through signal lines.

Alternatively, the System may be applied to the field of an L1-grade Driving Assistance System (ADAS).

The steering wheel control system only needs to add one controller 101 to the original automobile framework, or adopts the existing controller of the automobile integrated with the automatic steering wheel aligning function as the controller 101, namely, software corresponding to the automatic steering wheel aligning function is integrated in the existing controller of the automobile, and adjustment on the original automobile framework is not needed completely, so that the steering wheel control method is easier to realize.

Fig. 2 is a schematic diagram of a steering wheel control method provided by an embodiment of the present disclosure, where the method is executed by a computer device, for example, the controller 101 shown in fig. 1. As shown in fig. 2, the method includes:

in step 201, the state information of the steering wheel is acquired when the automobile is in a parking state.

In step 202, the steering wheel is controlled to return to positive in response to the status information of the steering wheel indicating that the steering wheel is not returning to positive.

In step 203, in the process of controlling the steering wheel to return to the normal state, the control of the steering wheel to return to the normal state is stopped in response to the interruption condition being satisfied.

By acquiring the state information of the steering wheel and controlling the steering wheel to return to the right state based on the state information, the automatic right return of the steering wheel after the automobile is parked is realized, the low right return efficiency or the non-right return of the steering wheel caused by insufficient driving experience of a novice driver is avoided, and the abrasion of the tire stress on a steering system and the collision risk of the automobile when the automobile is taken out of a garage next time due to the fact that the steering wheel is not returned to the right after the automobile is parked are reduced. In addition, in the process of controlling the steering wheel to return to the right state, when the interruption condition is met, the steering wheel is stopped to return to the right state, so that the damage to the automobile and the injury to people in the automobile caused by the forced return of the steering wheel can be avoided, and the safety of the automobile and the people in the automobile can be effectively guaranteed.

In some examples, controlling steering wheel return includes controlling steering wheel return when the vehicle is in a non-key-off state.

Fig. 3 is a schematic diagram of another steering wheel control method provided in the embodiments of the present disclosure. The method is used for controlling the steering wheel to automatically return to the normal state when the automobile is not flameout. The method may be performed by a controller, for example, by controller 101 in fig. 1. As shown in fig. 3, the method includes:

in step 301, the state information of the steering wheel is acquired while the vehicle is in a parking state.

The vehicle is in the park state, i.e., the wheel speed is 0 and the range is in the park range. The state information of the steering wheel includes a rotation angle of the steering wheel.

Alternatively, the state information of the steering wheel may be acquired, and at the same time, the wheel speed, gear information, ignition information, door lock information, and the like of the vehicle may be acquired.

For example, the controller may obtain the state information of the steering wheel detected by the steering angle sensor in the information system 104, obtain the wheel speed detected by the ESP, obtain the gear information detected by the TCU, obtain the ignition information detected by the PEPS, and obtain the door lock information detected by the BCM.

When the controller acquires that the wheel speed of the automobile is 0 and the gear of the automobile is placed in a parking gear, the automobile is in a parking state, and when any one of the two conditions is not met, the automobile is not in the parking state, and the current process is exited. For example, a corresponding standby condition may be set in the steering wheel control system shown in fig. 1, and the standby condition is used to measure whether the vehicle is in a parked state. The standby conditions include: the wheel speed of the automobile is 0; the automobile gear is arranged in the parking gear. When the above conditions are all met, the system keeps a standby state and requests the CGW to keep the current network in an awakening state; if any of the above conditions is not met, the system automatically shuts down.

Optionally, the steering wheel control system defaults to the last enabled function before controller 101 performs step 301. If the steering wheel control system is started for the last time and the non-flameout steering wheel returning function is started, the system can start the non-flameout steering wheel returning function by default at this time without switching the functions by a driver; if the steering wheel control system is started for the previous time and is the flameout steering wheel returning function, the system can default to start the flameout steering wheel returning function at this time, and the driver needs to switch to the non-flameout steering wheel returning function in the instrument system 103.

In step 302, it is determined whether the steering wheel is back-up based on the state information of the steering wheel.

And if the state information of the steering wheel indicates that the steering wheel is back to the right, exiting the current process. If the status information of the steering wheel indicates that the steering wheel is not back, step 303 is performed.

Optionally, when the rotation angle of the steering wheel does not exceed the angle threshold, indicating that the steering wheel is back to the right; and when the rotation angle of the steering wheel is larger than the angle threshold value, indicating that the steering wheel is not aligned. The angle threshold may be a preset angle value, and for example, the angle threshold may be ± 5 °. That is, when the rotation angle of the steering wheel does not exceed 5 °, it indicates that the steering wheel has returned to the right; when the rotation angle of the steering wheel is larger than 5 degrees, the steering wheel is indicated not to return to the right. Where "+" and "-" represent different directions of the steering wheel angle, e.g., "+" represents a left hand deflection of the steering wheel and "-" represents a right hand deflection of the steering wheel.

In step 303, a confirmation option is output for the driver to confirm whether or not to perform steering wheel return.

Illustratively, confirmation options may be output by the meter system 103, such as: the meter system 103 pops up a dialog box in which the "whether to perform steering wheel auto-correction" is prompted, and the driver can select the instruction "confirm" or "cancel" in the dialog box. In addition to the driver selecting either the "confirm" or "cancel" command, the driver may not select either command, i.e., not respond to the confirm option. If the driver does not respond to the confirmation option within a certain time period, the current process is exited, and the time period may be preset, for example, may be 10 s.

When the driver needs to automatically return to the right, a confirmation instruction can be input through a confirmation option, and the steering wheel is controlled to return to the right; when the driver does not need to perform automatic return correction, the return correction of the steering wheel can be cancelled by confirming that the option inputs a cancellation instruction.

Before the steering wheel is controlled to return to the right, the driver confirms firstly, so that the driver has better driving experience, the steering wheel is prevented from being controlled to return to the right when the driver does not need to return to the right, the identity of the driver can be highlighted, and the good sensibility of the driver to a product adopting the method is improved.

In step 304, the steering wheel is controlled to return to normal based on the confirmation command.

Wherein the confirmation instruction is input by the driver based on the confirmation option.

After receiving the confirmation instruction, the system requests a handshake entry with the electric power steering system to activate the lateral control function and sends a target steering wheel angle to the electric power steering system to instruct the electric power steering system to turn the steering wheel by the target steering wheel angle so that the steering wheel is returned to the normal state.

Optionally, controlling steering wheel alignment comprises:

in step 304a, a target angle value is determined based on the steering wheel angle and an angle threshold.

Alternatively, the target angle value may be the difference between the steering wheel angle and an angle threshold, e.g., a steering wheel angle of +8 °, an angle threshold of ± 5 °, the target angle value of-3 ° at this time, and if "+" indicates a left-hand steering wheel and "-" indicates a right-hand steering wheel, the target angle value "-3 °" at this time indicates a right-hand steering wheel deflection of 3 °.

In step 304b, the steering wheel is controlled to return to normal based on the target turning angle value.

Illustratively, steering system 105 controls the steering wheel to turn right based on the target angle value, e.g., steering system 105 controls the steering wheel to turn 3 ° left when the target angle value is "+ 3 °".

In step 304c, the steering angle of the steering wheel is acquired in real time during the process of controlling the steering wheel to return to the right.

In step 304d, judging whether the rotation angle of the steering wheel meets a stop-return-positive condition, if the rotation angle of the steering wheel meets the stop-return-positive condition, stopping controlling the steering wheel to return to positive, and requesting the CGW to be powered off and dormant, namely disconnecting the network connection state of each part in the steering wheel control system; if the angle of rotation of the steering wheel does not satisfy the stop and go condition, steps 304a-304d continue.

In this step 304d, the stop-and-go condition may include the steering wheel angle being less than or equal to an angle threshold. For example, when the steering wheel angle is-2 ° and the angle threshold is ± 5 °, and the stop return correction condition is satisfied, the control of the return correction of the steering wheel is stopped.

The steering wheel is controlled to return to the right by acquiring the real-time steering wheel corner, closed-loop control is formed, the steering wheel can be controlled to return to the right more accurately, and therefore a better control effect is achieved.

In step 305, in controlling the steering wheel to return to the normal state, the steering wheel is stopped from returning to the normal state in response to the interruption condition being satisfied.

In some embodiments, the interrupt condition includes failure to obtain status information of the steering wheel. For example, a communication failure may result in failure to obtain some or all of the status information of the steering wheel.

In other embodiments, the interrupt condition includes a return resistance of the steering wheel exceeding a resistance threshold. Illustratively, the aligning resistance may include the driver's resistance to the steering wheel and the resistance of obstacles on the ground to the steering of the car, such as: obstacles such as steps, stones, trees, etc. The resistance threshold may be pre-set.

In other embodiments, the interrupt condition includes a failure of a system that controls the steering wheel back to normal. For example: the hardware of the system for controlling the steering wheel to return to the right state is in failure, or the system hardware is normal but the steering wheel cannot be controlled to return to the right state. For example, the hardware device may be normal but not capable of controlling the steering wheel to return to normal due to a software program running in the system being in error, etc. When either of the above two conditions is met, the system for controlling the steering wheel to return to the positive state is in failure, and the automatic return of the steering wheel is interrupted.

In other embodiments, the interrupt condition includes the system controlling the steering wheel to return to normal receiving a shutdown command, i.e., the user manually shuts down the system.

In other embodiments, the interruption condition includes that the system for controlling the steering wheel to return to the normal state receives an operation command, and the operation command is used for controlling the wheel speed to be not 0 or the gear to be placed in the non-parking position, for example, in the process of controlling the steering wheel to return to the normal state, the driver operates the automobile, or the driver or the person in the automobile makes a false touch on the automobile, so that the wheel speed of the automobile is not 0 or the gear is placed in the non-parking position, the process of controlling the steering wheel to return to the normal state is interrupted.

In some embodiments, the interrupt condition includes at least one of the above conditions. The steering wheel is stopped from being controlled back to positive in response to any of the interrupt conditions being met and the CGW is requested to be powered down to sleep.

Alternatively, in response to the interruption condition being satisfied, the reason for the interruption, i.e., the satisfied interruption condition, is sent to the driver while stopping controlling the steering wheel to return to normal.

In the process of controlling the steering wheel to return to the right state, when the interruption condition is met, the steering wheel is stopped to return to the right state, so that the damage to the automobile and the injury to personnel in the automobile caused by the forced return of the steering wheel can be avoided, and the safety of the automobile and the personnel in the automobile can be effectively guaranteed. Meanwhile, the interruption reason is sent to the driver, so that the driver can know the reason for the automatic steering wheel return interruption to repair the steering wheel in time, and the automatic steering wheel return function can be continuously used subsequently.

In other examples, controlling steering wheel return includes controlling steering wheel return when the vehicle is in an off state.

Fig. 4 is a schematic diagram of another steering wheel control method provided in the embodiments of the present disclosure. The method is used for controlling the steering wheel to automatically return to the normal state when the automobile is in a flameout state. The method may be performed by a controller, for example, by controller 101 in fig. 1. As shown in fig. 4, the method includes:

in step 401, the state information of the steering wheel is acquired while the vehicle is in a parking state.

The method that the automobile is in the parking state means that the wheel speed is 0, the gear position is in the parking gear and the ignition information is OFF, namely that the automobile is in the flameout state.

For example, the controller may obtain ignition information detected by the PEPS.

Optionally, the standby condition of the steering wheel control system further includes, in addition to the embodiment shown in fig. 3: the ignition information is OFF, i.e. the vehicle is in a flameout state.

Optionally, the steering wheel control system defaults to the last enabled function before controller 101 performs step 401. If the steering wheel control system is started for the last time and the flameout steering wheel aligning function is started, the system can start the flameout steering wheel aligning function by default at this time without switching the functions by a driver; if the steering wheel control system is started for the last time and the non-flameout steering wheel returning function is started, the system can default to start the non-flameout steering wheel returning function at this time and needs the driver to switch to the flameout steering wheel returning function in the instrument system 103.

In step 402, it is determined whether the steering wheel is back aligned based on the state information of the steering wheel.

And if the state information of the steering wheel indicates that the steering wheel is back to the right, exiting the current process. If the status information of the steering wheel indicates that the steering wheel is not back, step 403 is performed.

In step 403, the steering wheel is controlled to return to normal.

Optionally, before the steering wheel is controlled to return to the normal state, whether the vehicle door is in the locked state is judged, if the vehicle door is locked, the steering wheel is controlled to return to the normal state, if the vehicle door is unlocked, a prompt message is sent to prompt a driver that the vehicle door is unlocked, and after the vehicle door is locked, the steering wheel is controlled to return to the normal state again.

Alternatively, the time for waiting for the door to be locked may be set in advance, for example, 500s, that is, if the door is locked within 500s in which the door is unlocked after the confirmation instruction is received, the steering wheel is continuously controlled to be returned, and if the door is not locked within 500s in which the door is unlocked after the confirmation instruction is received, the steering wheel is stopped to be returned.

Optionally, this step 403 may include steps 304a-304d as previously described.

In step 404, in controlling steering wheel return, in response to the interrupt condition being satisfied, controlling steering wheel return is stopped.

The interrupt condition includes that the ignition information is ON (ON), that is, the vehicle is in a non-flameout state, in addition to the interrupt condition in the embodiment of fig. 3.

Compared with the method in the embodiment shown in fig. 3, the method does not need to output the confirmation option and controls the steering wheel to return to the positive state based on the confirmation instruction, and can directly control the steering wheel to return to the positive state when the steering wheel is not returned according to the state information of the steering wheel. Therefore, when the driver forgets to return to the right after flameout, the steering wheel can be controlled to return to the right, and the abrasion of the tire stress on the steering system and the collision risk of the automobile when the automobile is discharged next time due to the fact that the steering wheel is not returned to the right after the automobile is parked are reduced.

Fig. 5 is a schematic diagram of a steering wheel control device provided in an embodiment of the present disclosure, and as shown in fig. 5, the device includes an obtaining module 501, a control module 502, and a stopping module 503.
