STEERING BY WIRE SYSTEM AND METHOD OF OPERATING THE SAME IN VEHICLE

Steer-by-wire systems and methods of operating such systems in a vehicle are described herein. A steer-by-wire system includes a steering wheel assembly including a steering wheel, a sensor, and a torque generator. The system includes a rack assembly including a steering rack, a sensor, and a rack actuator. The steering wheel assembly and the rack assembly are communicatively coupled by a steer-by-wire system controller without any direct mechanical connection between these assemblies. In some examples, a controller instructs a rack assembly to control a steering rack position based on a steering input, such as a change in steering wheel position. A desired steering rack position is determined based on the current steering wheel position using the steering map. In some examples, a steering map is selected from a set of steering maps based on, for example, vehicle speed, vehicle direction, driver preference, etc. 本文中描述了线控转向系统和在车辆中操作这些系统的方法。线控转向系统包括方向盘总成，方向盘总成包括方向盘、传感器和扭矩发生器。所述系统包括齿条总成，齿条总成包括转向齿条、传感器和齿条致动器。方向盘总
