Method and apparatus for controlling actuator in ventilator for vehicle

Abstract

A method and apparatus for controlling an actuator in a ventilator for a vehicle, controls an actuator which controls position of a door for a ventilator for a vehicle without having a particular feedback device. The actuator controlling method and apparatus counts the number of spike signals generated by a mechanical contact between a rotator and a brush of an actuator motor to then calculate the number of rotations of the motor and thus controls an actuator until the calculated number of rotations of the motor reaches the number of pulses up to a user's desired target position. Thus, the actuator motor can be accurately controlled without having any separate feedback circuit, to thereby control a door to be positioned at a user's desired position. Further, since a configuration of the actuator is simplified, a production cost can be reduced and control devices can be shared with each other.
