  • Publication number: 20130288857
    Abstract: A control method for a vehicle, which is equipped with a drive unit configured to drive a driving wheel and a controller configured to control the drive unit and receive an activation command for the drive unit from a user, includes determining whether the vehicle carries out coasting with the drive unit unactivated, determining whether the activation command has been received during the coasting, and limiting an actual braking force generated by the drive unit if the controller has received the activation command during the coasting, compared to a case where the vehicle runs in a state other than the coasting.

  • Publication number: 20130289814
    Abstract: A vehicle includes a drive unit that generates a driving force for driving a driving wheel, and an accelerator pedal. In the vehicle, the driving force generated by the drive unit is controlled on the basis of an operation amount of the accelerator pedal, which is operated by a user. It is determined whether or not the vehicle carries out coasting with the drive unit unactivated. It is determined whether a predetermined condition that an activation command for the drive unit be received from the user with the accelerator pedal operated is fulfilled during the coasting. An actual driving force that is transmitted from the drive unit to the driving wheel is limited with respect to a driving force that is required by the user, in comparison with a case where the vehicle travels in a state other than the coasting, if the predetermined condition is fulfilled.

  • Publication number: 20120226401
    Abstract: A vehicle includes an electric storage device, an internal combustion engine, an electric drive portion that generates a driving force of the vehicle using an electric power from the electric storage device and generates an electric power using a rotational force of driving wheels of the vehicle, and a control device configured to control a driving force from the engine and the driving force from the electric drive portion in a cooperative manner to cause the vehicle to travel. The control device causes the electric drive portion to perform an electric power generation operation to raise a rotational speed of the engine and start the engine, upon receipt of a request to start the engine in a state where the electric power from the electric storage device cannot be used to drive the electric drive portion and a vehicle speed is equal to or higher than a reference vehicle speed.
