MOTOR CONTROL SYSTEM FOR HYBRID VEHICLE AND METHOD FOR CONTROLLING THE SAME

摘要

PURPOSE: A motor driving system of hybrid vehicle and a malfunction control method thereof are provided to prevent electric shock of a driver and a helper when a car accident happen by discharging high voltage energy. CONSTITUTION: A motor driving system of hybrid vehicle includes the followings: a first and a second motors for car driving; a first inverter(1) controlling the first motor; a second inverter(2) driving the second motor; a battery(B) outputting the direct current voltage; a voltage converter(3) supplying voltage to a battery for DC power supply; a first and a second main relay(SR1,SR2) connected between the battery for the DC power supply and the voltage converter; a DC converter(4) connected between the voltage converter and the first and the second inverter; and an electric filed load(6) using a 12V sub battery(5) connected to the DC converter.
