Problems solved by technology
[0006] However, the conventional air flap sticking prevention device 100 does not cause the voltage change of the DC / DC conversion unit 160 to change in the external input voltage. When the action is affected, it will be difficult to perform normal actions, and when the air flap is stuck in the closed state, there will be a problem of engine heating because the air cannot flow into the engine room

The device for preventing air flaps from sticking according to the present invention is characterized in that it comprises: a motor drive power supply part for supplying power to the actuator motor; a motor drive current measurement part for measuring the drive current of the motor and outputting an electrical signal corresponding thereto The motor drive speed measurement unit measures the drive speed of the motor and outputs an electrical signal corresponding to it; the microcomputer outputs according to the electrical signal received from the motor drive current measurement unit and the motor drive speed measurement unit. a control signal for changing the voltage; and a DC / DC conversion section that outputs the changed voltage to the motor drive power supply section based on the control signal received from the microcomputer that increases the current of the drive motor . When the driving speed of the motor decreases, a control signal for increasing the output voltage of the DC / DC converter is output. The invention minimizes the air flaps being affected by external factors and helps safe driving.
Description
Technical field [0001] The present invention relates to a device and method for preventing adhesion of air flaps, and more specifically, to a device and method for preventing adhesion of air flaps using actuator motor velocity and current detection. Background technique [0002] The AAF system (Active Air Flap) is a system for controlling the openable and closable air flap between the radiator grille and the radiator. The AAF system closes the air flaps when the vehicle is driving at high speed to reduce the air resistance of the vehicle and help the stability of driving. In addition, when the temperature inside the engine room rises and the parts are heated, the air flaps are opened to allow cold outside air to flow in, thereby reducing the temperature inside the engine room. As mentioned above, the AAF system controls the opening / closing of the air flap. The AAF controller receives various vehicle conditions from the main components through the CAN network (Controller Area Ne...
