Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
FIG. 1 is a flow chart illustrating a method of controlling a wheel according to an exemplary embodiment. As shown in fig. 1, the method may include the following steps.
In step 101, after the driver leaves the vehicle, a wheel-return-positive remote control signal is transmitted to the vehicle.
In the present disclosure, after the driver leaves the vehicle, the wheel alignment may be controlled by operating a remote control device, which may be, for example, a vehicle remote key, a smart phone, a smart band, or the like.
In step 102, when the vehicle receives the wheel alignment remote control signal, it is detected whether the wheel is aligned.
In the disclosure, when the vehicle receives a wheel alignment remote control signal transmitted by the remote control device, it is first detected whether the wheel is aligned. Specifically, the wheel alignment may be determined in a variety of ways, and in one embodiment, the steering angle of the wheel may be obtained and then the wheel alignment may be determined based on the steering angle. Wherein when the steering angle of the wheel exceeds a first preset angle range (e.g., -5 ° to 5 °), it may be determined that the wheel is not aligned; when the steering angle of the wheel is within the above-described first preset angle range, it may be determined that the wheel is in the return state.
In another embodiment, the steering angle of the steering wheel may be obtained and then followed to determine whether the wheels are back aligned. Wherein when the rotation angle of the steering wheel exceeds a second preset angle range (e.g., -5 ° to 5 °), it may be determined that the wheels are not aligned; when the rotation angle of the steering wheel is within the second preset angle range, it can be determined that the wheels are in the aligning state.
The first preset angle range and the second preset angle range may be set by the driver or may be default, and may be equal to or different from each other, and are not particularly limited in the present disclosure.
When the wheel is determined to be in the non-return state, controlling the steering mechanism to act so as to return the wheel to the return state (namely executing the following step 103); when it is determined that the wheel is in the return state, no operation is performed, i.e., the end.
In step 103, the steering mechanism is controlled to operate so as to return the wheels to a normal position.
In the present disclosure, the steering mechanism may include a steering shaft, a steering motor, a steering assist pump, and the like. Before controlling the action of the steering mechanism, the steering wheel needs to be controlled to unlock so that the steering mechanism can work, and then the wheels are driven to rotate, and the steering mechanism is controlled to stop acting until the wheels return to the right.
Through the technical scheme, after the driver leaves the vehicle, the wheels are rightly returned conveniently through the control of the remote control device, and the trouble that the driver gets on or off the vehicle back and right the wheels is avoided. In addition, the damage of a steering system, a suspension system or tires caused by the fact that wheels are not aligned when the vehicle is parked for a long time is reduced, the occurrence of vehicle safety accidents is reduced, and the driving safety is improved.
In addition, since the periphery of the wheel, particularly the inner side of the wheel, is a blind area for the driver, the driver cannot observe the inner side of the wheel, and if an obstacle is present in the area, if the wheel is forcibly aligned, the tire is easily scratched by the obstacle. Alternatively, when the obstacle resistance is too large, if the vehicle is forcibly steered back, there is a high possibility that the steering motor or the steering shaft of the steering mechanism is damaged. In addition, when the obstacle is a creature such as a small animal, if the vehicle is forcibly turned right, the life safety of the small animal may be threatened. Therefore, before controlling the steering mechanism to operate, it is necessary to determine whether or not an obstacle is present in the target return region of the wheels, and to control the steering mechanism to operate so as to return the wheels to normal, when it is ensured that no obstacle is present in the target return region of the wheels. Specifically, as shown in fig. 2, the method may further include the following steps.
In step 104, it is determined whether an obstacle is present in the target return region of the wheel.
In the present disclosure, the above-mentioned target return region may be a region through which the wheel rotates from the current position to the return position, that is, the target return region is a sum of regions through which the left front wheel, the rear front wheel, the left rear wheel, and the right rear wheel of the vehicle each rotate from the current position thereof to the return position. For example, as shown in fig. 3, the area through which the front left wheel rotates from the current position to the return position is the area a and the area B shown by the hatched portion, the area through which the front right wheel rotates from the current position to the return position is the area C and the area D shown by the hatched portion, the area through which the rear left wheel rotates from the current position to the return position is the area E and the area F shown by the hatched portion, and the area through which the rear right wheel rotates from the current position to the return position is the area J and the area H shown by the hatched portion, the target return area is the sum of the area a, the area B, the area C, the area D, the area E, the area F, the area J, and the area H, that is, all the hatched areas shown in fig. 3.
In one embodiment, whether an obstacle exists in the target return area may be detected by a radar, an image capture device (e.g., a camera), or the like. The radar or the image acquisition device can be arranged on the vehicle body, and also can be arranged on a vehicle component fixed with the position of the vehicle body, and the detection of whether an obstacle exists in a target aligning area of the wheel can be realized. For example, the radar or the camera may be disposed on a metal plate on the inner side of the wheel, at the bottom of a front subframe of the vehicle, in a front bumper grille of the vehicle, or the like.
Returning to fig. 2, when it is determined that no obstacle exists in the target return area of the wheel, the steering mechanism may be controlled to operate so as to return the wheel to the original position (i.e., the above-described step 103 is performed); and when it is determined that an obstacle is present in the target alignment area of the wheels, the steering mechanism may be controlled to remain stationary so that the wheels are stationary (i.e., the following step 105 is performed). Therefore, the damage to the tire and the steering mechanism can be avoided, and the life safety of the obstacle can be ensured when the obstacle is a creature such as a small animal.
In step 105, the steering mechanism is controlled to remain stationary to bring the wheels to rest.
