Abstract
A system for controlling a motor of a vehicle that improves fuel economy by minimizing a sum of heat generated by the motor and heat generated by a converter, is disclosed. More specifically, a power source supplies DC electricity; a converter selectively receives and converts the DC electricity of the power source into inverter input voltage. A relay module selectively connects the power source to the converter and an inverter module receives the inverter input voltage from the converter, converts the inverter input voltage into 3-phase AC current, and supplies the 3-phase AC current to the motor. Further, a controller controls operations of the converter, the relay module, and the inverter module, to perform to minimize the inverter input voltage that is a sum of heat generated due to the flux-weakening control and heat generated due to suppression of the flux-weakening control.
