PURPOSE:To avoid instantaneous overload of an engine by delaying clutch engaging control by a predetermined time when the vehicle advancing direction and shift lever position differ in frequent forward and backward operations on a muddy spot or the like. CONSTITUTION:Signals from a clutch drive shaft rotation sensor 20, same driven shaft rotation sensor 40, throttle opening sensor 12 and shift lever position sensor 13 are applied to the input of a microprocessor 90. This microprocessor 90 judges the advancing direction of a vehicle on the basis of signals from the driven shaft rotation sensor 40. When said direction is contrary to the shift lever position, the microprocessor 90 delays controllably clutch engagement by a predetermined time. Thus, the clutch is engaged when the rotation frequency of the clutch driven shaft is low so that shock and engine stop of the vehicle can be avoided. |
