Abstract

PURPOSE:To improve the controlling accuracy and the electric power efficiency, by controlling an electromagnetic valve of a flow controlling section while a dither is being dispatched from the valve. CONSTITUTION:The output pulses of a car speed sensor 10 are amplified by an amplifier 11A, and then are shaped by a wave-shaping apparatus 11B into square waves. The output from the wave-shaping apparatus 11B is converted at a frequency-to-voltage converting circuit 12 to a voltage value corresponding to the frequency, and the output thereof is processed in an operational amplifier 13 to output an electromagnetic valve driving signal. The signal from the circuit 13 together with the fed-back driving value of the electromagnetic valve 17 are added at an adding circuit 14, the result is pulse-width converted at a pulse- width modulation circuit 15, and by the output thereof, the electromagnetic valve 17 is controlled through a transistor 16 while a dither is being dispatched therefrom.
