Abstract
A smart electronic power steering system and method for a retrofitted electric vehicle are provided. In one embodiment, an electronic power steering system comprises a relief valve; a pump in communication with the relief valve; a motor configured to operate the pump; a motor controller configured to control the motor; and a processor. The processor is configured to receive a desired maximum pressure value from a retrofitted electric vehicle and configure the relief valve or motor controller to provide relief at the desired maximum pressure value; and receive a desired flow rate from the retrofitted electric vehicle and configure the motor controller to operate the motor at a speed to achieve the desired flow rate. Other embodiments are provided.
