Abstract: PURPOSE: A hill holding control method of a hybrid vehicle is provided to stably maintain a vehicle in a sloped road by increasing torque for hill holding. CONSTITUTION: A hill holding control maintaining the stop state of a vehicle using only an electric motor is executed when a hybrid vehicle stops in uphill during an EV mode. A HCU which is a master controller of a hybrid vehicle executes a torque instruction for the hill holding. The sensing signal of a resolver(102) sensing the rotational phase angular of a motor passes through a RDC(Resolver-to-Digital Converter)(104) and is inputted to a motor controller(100) as an input signal. The motor controller controls the motor output of an inverter power module(90) in order to execute the hill holding of a motor by varying the rotation angle of a motor to minimize a current.

Abstract: A method for diagnosing a defect of a DC-DC converter of an electric vehicle is provided to lengthen durability of the DC-DC converter and an auxiliary battery in a hybrid/fuel cell vehicle by diagnosing rapidly the defect of the DC-DC converter. A low-voltage DC-DC converter outputs a voltage according to a voltage command received from an external controller and monitors simultaneously an output voltage. The voltage command and the real output voltage are compared with each other in order to diagnose a defective state of a DC-DC converter. When a difference between the voltage command and the real output voltage exceeds a reference voltage and the exceeding time of the reference voltage is maintain during a constant period, the defective state is diagnosed. The low-voltage DC-DC converter generates a defective diagnosis code and turns on an alarm lamp.
