<p>In a vehicle electromagnetic clutch control device, clutch current calculating means outputs a clutch current analog signal according to given travel control data and engine control data, a current difference detector obtains the difference between the clutch current analog signal and a clutch current feedback signal, a first output transistor is operated according to the difference thus obtained to energize the electromagnetic clutch, the clutch current flowing in a second output transistor is detected with a current detecting resistor, and a voltage corresponding to the clutch current thus detected is applied to an operational amplifier, so as to output the clutch current feedback signal with the aid of a reference resistor, a feedback resistor and the amplification factor thereof. An adjusting resistor is connected in parallel to the reference resistor, to adjust the clutch current. Thus, the adjustment of the clutch current can be achieved without removal of the reference resistor and the feedback resistor from the printed circuit board.</p> |
