Clutch engagement control in a power transmission arrangement for vehicles

摘要

A power transmission arrangement for a vehicle adapted to transmit a drive power from an engine (76) to a transmission (75) via a wet multi-plate clutch (52). An electronic controller (79) automatically disengages and engages the clutch normally, but does not engage the clutch if a transmission gear position other than a predetermined one is selected for starting of a vehicle. This prevents clutch engagement with an excessively high gear position. Otherwise, the clutch would overslip and be deteriorated soon. A torque converter (53) may further be provided in tandem to the clutch so that the engine power is transmitted to the transmission through the clutch and torque converter.
