The invention provides a steering wheel aligning torque weakening method, and belongs to the technical field of vehicle electronic control, and the method comprises the steps: substituting lane curvature and steering wheel angle collected in real time into a pre-stored corresponding relation to obtain a reverse aligning torque coefficient, obtaining steering wheel reverse aligning torque according to the reverse aligning torque coefficient and steering wheel aligning torque, and reducing the steering wheel aligning torque according to the steering wheel reverse aligning torque coefficient. Furthermore, the steering wheel aligning torque is updated according to the steering wheel reverse aligning torque, and finally, a power-assisted motor of the steering wheel is controlled according to the updated steering wheel aligning torque, so that when the vehicle turns, the steering wheel aligning torque is properly reduced; a driver only needs to apply small steering torque to the steering wheel, the vehicle can be kept in the lane to complete turning, the vehicle control difficulty of the driver is lowered, and the fatigue of the driver during vehicle driving is lowered.

    本申请提供了方向盘回正力矩减弱方法,属于车辆电控技术领域,方法包括根据实时采集的车道曲率和方向盘角度,代入预先存储的对应关系中从而得到逆回正力矩系数,根据逆回正力矩系数和方向盘回正力矩,得到方向盘逆回正力矩,进一步根据方向盘逆回正力矩对方向盘回正力矩进行更新,并最终根据更新后的方向盘回正力矩控制方向盘的助力电机,从而在车辆转弯时,适当减小方向盘回正力矩,使驾驶员只需要对方向盘施加较小的转向力矩即可以使车辆保持在车道中完成转弯,降低了驾驶员的控车难度,以及驾驶员在驾驶车辆时的疲劳度。
