Patent ID: 7023152

Claim:
A driving control device for an actuator comprising: a drive circuit configured to drive an electric motor of an actuator for opening and closing an air conditioning door; and a drive control circuit configured to control a rotation of said electric motor by controlling the drive circuit, wherein said drive circuit includes an H bridge circuit having a switching semiconductor element, wherein said drive circuit is configured to rotate said electric motor in forward and reverse directions by turning on and/or off said switching semiconductor element, wherein said drive control circuit is configured to start and/or stop said electric motor by applying a PWM signal to the switching semiconductor element constructing a lower arm of said H bridge circuit, wherein said drive control circuit is capable of selecting a first mode for applying the PWM signal, or a second mode for applying a driving pulse, to the switching semiconductor element constructing said lower arm, wherein said drive control circuit is communicatedly connected to a radio, and wherein said drive control circuit is configured to apply the driving pulse when said radio is turned on and is configured to apply the PWM signal when said radio is turned off.
