A steer-by-wire steering system for a vehicle and a method of operating the same are detailed. A steer-by-wire steering system has a steering wheel, a first sensor for capturing a steering angle of the steering wheel, a processing logic for determining a wheel set angle demand based on the captured steering angle, and an actuator unit for setting a wheel setting angle at a wheel of the vehicle according to the wheel setting angle demand determined by the processing logic unit. The sensor is electrically connected to the actuator unit and is supplied with electrical energy via the actuator unit. There is at least one further sensor for capturing the steering angle of the steering wheel, which further sensor is used as a standby solution if the first sensor has failed, wherein the processing logic unit is configured to predominantly process the signal from the first sensor and to process the signal from the further sensor only when the first sensor fails.
详述了一种用于车辆的线控转向转向系统及其操作方法,该线控转向转向系统具有方向盘、用于捕获方向盘的转向角度的第一传感器、用于基于所捕获的转向角度确定车轮设定角度需求的处理逻辑单元、以及用于根据由处理逻辑单元所确定的车轮设定角度需求将车轮设定角度设定到车辆的车轮处的致动器单元。传感器电连接至致动器单元并且经由致动器单元被供应电能。存在用于捕获方向盘的转向角度的至少一个另外的传感器,如果第一传感器发生故障,则该另外的传感器被用作备用解决方案,其中处理逻辑单元被配置成主要处理来自第一传感器的信号并且仅在第一传感器发生故障时处理来自另外的传感器的信号。
