Abstract

The invention discloses a vehicle, and a steering reversal control device and method of the vehicle. The device comprises a first position detecting assembly, a second position detecting assembly, an angular velocity detecting assembly, a parameter detecting assembly, and a control unit, wherein the first position detecting assembly is arranged at a wheel steering knuckle, and used for detecting the spatial position parameter of the wheel steering knuckle; the second position detecting assembly is arranged at a swing arm ball head, and used for detecting the position information of the swing arm ball head; the angular velocity detecting assembly is used for detecting the yawing angle velocity of a wheel master pin; the parameter detecting assembly is used for detecting motor assistance influence parameters; and the control unit is connected with the first position detecting assembly, the second position detecting assembly, the angular velocity detecting assembly and the parameter detecting assembly separately, and used for obtaining wheel positioning information according to the spatial position parameter of the wheel steering knuckle and the position information of the swing arm ball head, and obtaining reversal signals according to the positioning information of a wheel, the motor assistance influence parameters and the yawing angle velocity of the wheel master pin, so as to perform reversal control on an assisted motor of the vehicle according to the reversal signals, so that reversal control can be correctly performed in a comfortable manner, and reversal effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle steering return control device, a vehicle and a vehicle steering return control method. Background technique [0002] The vehicle steering system in the related art usually measures the rotation angle of the steering wheel in real time by adding a rotation angle sensor or a motor rotation angle position sensor on the vehicle booster motor, so as to ensure that the steering wheel returns to the right position. However, the existing problems are that the accuracy of the centering control is low, there is a residual angle, and the user satisfaction is low. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the first object of the present invention is to provide a steering return control device for a vehicle, which can realize comfortable and accurate return con...
