Abstract
A valve control device includes a drive circuit for supplying a drive signal to an actuator adjusting an opening degree of a valve via a prescribed transmission line, generates a PWM signal on the basis of a target opening degree supplied from the outside and a sensor signal that indicates a real opening degree of the valve, and supplies the PWM signal to the drive circuit. The valve control device includes a disconnection detection unit which detects, on the basis of the PWM signal and a monitor signal of the drive signal, whether the transmission line is disconnected.
