DEVICE FOR CONTROLLING POWER TRANSMISSION OF VEHICLE

摘要

This device for controlling power transmission is used in a hybrid vehicle having an internal combustion engine and a motor (MG) as power sources. The device comprises a manual transmission and a frictional clutch. In a state in which the MG torque has been adjusted to vehicle-decelerating regenerative torque, the magnitude of the regenerative torque is reduced to a "very small value greater than zero" and is thereafter kept at the very small value A when the clutch has been moved to a fully disengaged state by the clutch pedal operation of the driver (at time t2). More energy produced by regeneration can be stored in a battery (refer to the area shown by dots), and energy efficiency (fuel efficiency) is improved in comparison with a case in which the regenerative torque is immediately adjusted to zero in accompaniment with the movement of the clutch to the fully disengaged state.
