A method for determining a steering wheel overlay torque delivered to a steering wheel of a steer-by-wire system is disclosed. An example steering-by-wire system includes a steering wheel actuator in operative connection with a steering wheel, a road wheel actuator in operative connection with a steered wheel of a vehicle, and a programmable circuit in communication with the steering wheel actuator and the road wheel actuator, and programmable circuitry for at least instantiating or executing machine-readable instructions to identify a superimposed force applied by a road wheel actuator, the superimposed force from a driver assistance function, identify a torque experienced by the steering wheel, determine a steering wheel torque corresponding to the superimposed force and the torque experienced by the steering wheel, and transmit the determined steering wheel torque to the driver assistance function. And determine an overlay torque for a steering wheel actuator based on the steering wheel torque and the torque received by the steering wheel.
本发明公开一种用于确定传递到线控转向系统的方向盘的方向盘叠加扭矩的方法。示例线控转向系统包括与方向盘操作性连接的方向盘执行器、与车辆的转向轮操作性连接的道路车轮致动器以及与方向盘执行器和道路车轮致动器通信的可编程电路,该可编程电路至少用于实例化或执行机器可读指令以识别由道路车轮致动器施加的叠加力,该叠加力来自驾驶员辅助功能,识别方向盘受到的扭矩,确定与叠加力和方向盘受到的扭矩相对应的方向盘扭矩,并基于方向盘扭矩和方向盘受到的扭矩确定用于方向盘执行器的叠加扭矩。
