方向盘转向的控制方法、装置和车辆
By acquiring and controlling the vehicle's basic torque and return torque in a closed loop, the target torque is determined to reduce the risk of torque vibration in the steer-by-wire system, thereby achieving smoothness and consistent feel in steering wheel control.

AI Technical Summary
Technical Problem
In vehicle steering control, there is a risk of torque oscillation when the steering wheel switches between the basic torque and the return torque, which affects the smoothness of the driver's control.
Method used
By acquiring the vehicle's basic torque and return torque, the target torque is determined based on their magnitude relationship, and closed-loop control is performed to ensure that the motor output torque matches the target torque, thus achieving a smooth transition between torque control and angle control of the steering wheel.
Benefits of technology
This reduces the risk of torque vibration during the transition between the basic torque and the return torque, and improves the smoothness and consistency of the feel transition.

Abstract
本申请公开了一种方向盘转向的控制方法、装置和车辆。该方法包括：获取车辆对应的基本力矩及回正力矩，其中，基本力矩为车辆的方向盘转动方向盘角度时，方向盘所产生的力矩，回正力矩为使方向盘按照预设的转动速度回正的力矩；根据基本力矩与回正力矩之间的大小关系，从基本力矩和回正力矩中确定目标力矩；根据目标力矩对电机的输出力矩进行闭环控制，得到电机的目标输出力矩；通过目标输出力矩控制方向盘转动。本申请实施例所提供的方案能够降低基本力矩与回正力矩切换所存在的力矩振动风险，提升了手感过渡的平顺性。
