Abstract:
A system for reducing motor drive loss in a vehicle. The system includes a motor designed to convert electrical energy into torque. The system also includes a sensor designed to detect motor data corresponding to at least one of a motor torque or a motor speed of the motor. The system also includes a memory designed to store testing data including optimized current commands for multiple combinations of motor torques that were determined during testing of the motor or a similar motor. The system also includes a speed or torque controller coupled to the motor, the sensor, and the memory and designed to receive a speed or torque command and to determine a current command signal usable to control the motor based on the speed or torque command, the testing data, the detected motor data, and an artificial intelligence algorithm.
