무엇보다도, 전동 조향 토크 보상을 위한 기술을 설명한다. 컴퓨터, 예를 들면, 자율주행 차량에 탑재된 컴퓨터에 의해 구현되는 방법을 위한 기술이 제공된다. 차량에 탑재되고 차량의 EPS에 연결된 계획 회로는 조향 휠의 예상된 조향각과 매칭하도록 차량의 조향 휠의 실제 조향각을 수정하기 위해 보상 토크 신호를 결정한다. 계획 회로는 보상 토크 신호를 조향 휠의 조향각을 제어하는 제어 회로에 송신한다. EPS는 보상 토크 신호에 기초하여 실제 조향각을 수정하여 수정된 조향각을 야기한다. 제어 회로는 수정된 조향각에 기초하여 차량을 동작시킨다.

    A computer-implemented method is provided for electric power steering torque compensation, e.g. onboard an autonomous vehicle. A planning circuit onboard the vehicle and connected to an EPS of the vehicle receives a plurality of compensatory torque signals, each being a data pair including a torque signal and a corresponding actual steering angle. The plurality of compensatory torque signals is used to determine a compensatory torque signal to modify an actual steering angle of a steering wheel of the vehicle to match an expected steering angle of the steering wheel. The planning circuit transmits the compensatory torque signal to a control circuit that controls the steering angle of the steering wheel. The EPS modifies the actual steering angle based on the compensatory torque signal resulting in a modified steering angle. Typically, determining the expected steering angle involves curve fitting a polynomial surface relating vehicle speed and steering angle to applied torque. A vehicle and a computer readable medium are also provided.
