Abstract: Methods and systems are provided for aligning a steering system of a vehicle. In one embodiment, a method includes: determining when the vehicle is driving a straight-line path; determining a steering wheel position error when the vehicle is driving the straight-line path; computing a rear wheel steering offset based on the steering wheel position error; and generating a control signal to a rear wheel steering system based on the rear wheel steering offset.

Abstract translation: 提供了用于对准车辆的转向系统的方法和系统。 在一个实施例中，一种方法包括：确定车辆何时驾驶直线路径; 当车辆行驶直线路径时确定方向盘位置误差; 基于方向盘位置误差计算后轮转向偏移; 并且基于后轮转向偏移量向后轮转向系统生成控制信号。

In one embodiment, a method includes: determining when the vehicle is driving a straight-line path; determining a steering wheel position error when the vehicle is driving the straight-line path; computing a rear wheel steering offset based on the steering wheel position error and a closed loop control method; and generating a control signal to a rear wheel steering system based on the rear wheel steering offset.
