<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 14 obtains the difference between the clutch current analog signal SIA and a clutch current feedback signal SF, a first output transistor 11 is operated according to the difference thus obtained to energize the electromagnetic clutch, the clutch current flowing in a second output transistor 12 is detected with a current detecting resistor 13, and a voltage corresponding to the clutch current thus detected is applied to an operational amplifier 61, so as to output the clutch current feedback signal with the aid of a reference resistor 63, a feedback resistor 62 and the amplification factor thereof. An adjusting resistor 64 connected in parallel to the reference resistor, to adjust the clutch current. A deexciting resistor for supplying a deexciting current to the electromagnetic clutch when the second output transistor is non-conductive, a clutch current averaging filter for receiving the clutch current feedback signal, and a supply voltage detecting means are also disclosed. <IMAGE></p> |
