<p>In a vehicle electromagnetic clutch control device, a PWM modulator is provided in a microcomputer. In the microcomputer, a PWM modulation signal is calculated according to travel control data and engine control data and is then outputted. The PWM modulation signal is buffered by a digital signal buffer, the output of which is passed through a PWM smoothing filter to remove high frequency components of the signal. The output of the PWM smoothing filter is input to an analog buffer amplifier to output a substantially DC current instruction signal to a PWM comparator.</p> |
