Abstract

A motor driving device for a vehicle relates to a technology for preventing motor deterioration by controlling a stall current when a motor is controlled for vehicle air-conditioning. The motor driving device includes: a stall current detector that outputs a current detection signal by detecting a stall current of a motor, a controller that pre-stores a control specification of the motor, and outputs a control signal in response to the control specification when the current detection signal is activated; and an output driver that outputs a drive signal for controlling driving of the motor in response to the control signal.

Description

technical field [0001] The present invention relates to a motor drive device for a vehicle, and more particularly, to a technique for preventing deterioration of a motor by controlling a stall current when the motor is controlled for vehicle air conditioning. Background technique [0002] Generally, an air conditioner is installed in a vehicle to properly maintain temperature, humidity, and air environment in response to changes in the surrounding environment, so that a driver and passengers of the vehicle can be provided with a comfortable environment. [0003] Recently, air conditioning systems of vehicles have become automated so that the temperature and airflow desired by the vehicle driver are established. The automatic temperature control device of the air conditioning system automatically drives the blower, or controls the speed of the blower, in response to signals detected by various sensors, thereby resulting in purification of the air inside the vehicle. [0004]...
