Vehicle with clutch for transmission of torque output of motor

摘要

A vehicle comprises a motor ( 4 ) and a wet clutch ( 12 ) for transmission of torque output of the motor to road wheels of the vehicle and transmission of road load from the road wheels to the motor ( 4 ). The wet clutch is disengaged in response to a clutch disengagement control signal. Accounting for clutch drag state of the wet clutch, a controller ( 8 ) selects one out of various values as threshold (Voff). The controller ( 8 ) determines that the wet clutch be disengaged when a parameter indicative of the actual vehicle speed has a predetermined relationship with the threshold. The controller ( 20 ) generates the clutch disengagement control signal upon determining that the wet clutch be disengaged.
