Abstract: PURPOSE:To detect the trouble of a solenoid coil, a driving transistor, etc., and also to miniaturize the driving device of a duty solenoid by obtaining the function which controls the energizing current of the solenoid coil into a specified objective value by a microcomputer. CONSTITUTION:The PWM pulse width modulation signal produced by a PWM timer 60 is outputted through the output terminal OUT 3 of a microcomputer 62. Then the transistors TR 31 and 27 work in response to the PWN signal to drive a solenoid coil 17. An integrator 63 smoothes the Q-point voltage. The microcomputer 62 detects the average current of the coil 17 to increase the duty rate of the PWM signal when the measured current of the coil 17 is lower than a target level and to reduce the duty rate vice versa. Thus the circuit constitution is simplified, therefore a driving device of a duty solenoid valve can be miniaturized. At the same time, such troubles can be detected as the disconnection of the coil 17, the short circuit of the TR 27, etc.
