VEHICLE CONTROL APPARATUS

摘要

A vehicle control device includes an engine, an electric motor, a clutch, and a hydraulic power transmission device having a lockup clutch disposed on a power transmission path between the electric motor and drive wheels, the control device increasing the electric motor output torque while slip-engaging or releasing the lockup clutch when the engine is started by engaging the clutch during motor running performed by using only the electric motor as a drive force source for running with the clutch released and the lockup clutch engaged, the control device raising the clutch actual torque capacity toward clutch engagement after starting an increase in the electric motor output torque when a torque difference between a torque capacity of the lockup clutch and the output torque of the electric motor falls within a predetermined range as the torque capacity of the lockup clutch is reduced at the start of the engine.

主权项

1. A control device of a vehicle including an engine, an electric motor configured to output power for running and power required for starting the engine, a clutch disposed on a power transmission path between the engine and the electric motor, and a hydraulic power transmission device having a lockup clutch disposed on a power transmission path between the electric motor and drive wheels, the control device increasing an output torque of the electric motor while slip-engaging or releasing the lockup clutch when the engine is started by engaging the clutch during motor running performed by using only the electric motor as a drive force source for running with the clutch released and the lockup clutch engaged,
the control device raising an actual torque capacity of the clutch toward engagement of the clutch after starting an increase in output torque of the electric motor when a torque difference between a torque capacity of the lockup clutch and the output torque of the electric motor falls within a predetermined range as the torque capacity of the lockup clutch is reduced at the start of the engine.
