Abstract:
An electronic control unit (ECU) may receive, from an autonomous vehicle controller, an instruction to set a hydraulic steering actuator, of a vehicle, to a particular machine steering angle setting. The ECU may provide, to a steering controller torque device, a current to set a steering controller, of the vehicle, to a particular steering controller angle that corresponds to the particular machine steering angle setting. The ECU may provide, to a hydraulic control system, a current to set the hydraulic steering actuator to the particular machine steering angle setting.
