Abstract: The present technology describes systems and methods for varying a pump speed of an electric truck. In examples, vehicle efficiency losses may be reduced by varying the speed of a hydraulic pump associated with a power steering gear. An electronic control unit (ECU) may receive a set of steering information from a torque overlay system (TOS). Based on the set of steering information, a power may be provided to a variable pump motor. The power provided to the variable pump motor may correspond with a speed of a hydraulic pump associated with a power steering gear of the vehicle. As new or additional steering information is received from the TOS, the ECU may adjust the power provided to the variable pump motor.
