发明名称 APPARATUS FOR DETECTING OVER CURRENT OF DUAL MOTOR IN VEHICLE
摘要 An apparatus for over current detection of a dual motor for use in a vehicle. This invention prevents each motor from burning out by more precisely detecting an over current of each motor in the dual motor within an overall drive area of the dual motor. This can be accomplished by setting, as an over current detection reference current, a predefined range between a normal current and a constraint current of each motor by drive input conditions of each use motor, detecting a current of each motor flowing in field effect transistor (FET) via a shunt resistor and a differential amplifier, and comparing the detected currents with the over current detection reference currents.
