VEHICLE CONTROL APPARATUS

摘要

To provide a driving system for a vehicle that can fulfill both drivability and regeneration efficiency. The driving system for the vehicle includes: an engine; a motor generator connected to a wheel; a clutch that changes transmission state between a disengagement state in which the engine is disengaged from the motor generator and an engagement state in which the engine is at least slightly engaged with the motor generator; and a one-way clutch capable of transmitting only power in a forward rotational direction from the engine to the motor generator, in which, when the power of the engine is transmitted to the motor generator, a first transmission method for transmitting the power through the one-way clutch with the clutch left disengaged and a second transmission method for transmitting the power through the clutch with the clutch engaged are changed in accordance with a vehicle state.

主权项

1. A control apparatus for a vehicle comprising:
an internal combustion engine; an electric motor connected to a wheel; a clutch configured to change between a disengagement state in which the internal combustion engine is disengaged from the electric motor and an engagement state in which the internal combustion engine is engaged with the electric motor; and a one-way clutch configured to transmit only power in a forward rotational direction from the internal combustion engine to the electric motor, an electronic control unit configured to: i) change a first transmission method for transmitting the power through the one-way clutch with the clutch disengaged and a second transmission method for transmitting the power through the clutch with the clutch engaged in accordance with rotational speed of the internal combustion engine when the power of the internal combustion engine is transmitted to the electric motor; and ii) change the first transmission method to the second transmission method and transmit the power of the internal combustion engine to the wheel through the electric motor when the rotational speed of the internal combustion engine becomes greater than a specified value that is determined in advance.
