Claims

[Claims for Utility Model Registration] A valve provided to adjust the characteristics of an exhaust system or an intake system of an internal combustion engine, an actuator that operates the valve using a motor as a drive source, and a position of the valve to a target position. a control circuit that generates a forward rotation command signal and a reverse rotation command signal that respectively command forward rotation and reverse rotation of the motor in order to rotate the motor forward and reverse rotation; and a drive circuit that drives the motor in accordance with the forward rotation command signal and the reverse rotation command signal. In the internal combustion engine control device, a power supply circuit in the internal combustion engine ignition device that receives the output of an exciter coil provided in an alternator installed in the internal combustion engine and outputs a constant DC voltage is shared as a power source for the control circuit. and the drive circuit is triggered by the normal rotation command signal and conducts with the actuator drive power generation coil provided in the alternator, and the actuator drive power generation coil is connected to the output voltage of one half cycle of the actuator drive power generation coil. a forward rotation switch element that causes a forward rotation drive current to flow through the motor; and a reverse rotation switch element that is triggered by the reverse rotation command signal and conducts, and causes a reverse rotation drive current to flow through the motor at the output voltage of the other half cycle of the actuator drive generating coil. An internal combustion engine control device characterized by comprising a switch element.
