Abstract
Official abstract text for this publication.
A vehicle control device includes a motor, a clutch and a control unit. The motor is configured to apply torque to a power transmission path between an engine and a drive wheel. The clutch is disposed between the engine and the drive wheel. The control unit stops fuel injection of the engine when the engine is greater than or equal to a prescribed engine rotational speed during deceleration, and restarts the fuel injection after disengaging the clutch, and then stops the power running of the motor after resuming the fuel injection of the engine. The control unit drives the motor to carry out power running such that a deceleration of the vehicle becomes less than or equal to a prescribed value when fuel injection of the engine is stopped.
First claim
Opening claim text (preview).
1 . A vehicle control method for controlling a vehicle having a motor configured to apply torque to a power transmission path between an engine and a drive wheel, and a clutch between the engine/motor and the drive wheel, the vehicle control method comprising: driving the motor to carry out power running such that a deceleration of the vehicle becomes less than or equal to a prescribed value when fuel injection of the engine is stopped while decelerating and an engine rotational speed is greater than or equal to a prescribed engine rotational speed; and restarting the fuel injection after disengaging the clutch, and then stopping the power running of the motor after resuming the fuel injection of the engine. 2 . The vehicle control method according to claim 1 , wherein the fuel injection of the engine is restarted when the deceleration of the vehicle is greater than a prescribed value while the fuel injection of the engine is stopped. 3 . (canceled) 4 . A vehicle control device comprising: a motor configured to apply torque to a power transmission path between an engine and a drive wheel; a clutch disposed between the engine and the motor and the drive wheel; a fuel cut control unit that stops fuel injection of the engine when the engine rotational speed is greater than or equal to a prescribed engine rotational speed during deceleration, and that restarts the fuel injection after disengaging the clutch, and then stops the power running of the motor after resuming the fuel injection of the engine; and a deceleration control unit that drives the motor to carry out power running such that a deceleration of the vehicle becomes less than or equal to a prescribed value when fuel injection of the engine is stopped.
