  • Patent number: 11046324
    Abstract: A control device for a multi-stage automatic transmission-equipped vehicle includes a hydraulic power controller, a combustion controller configured to, if a predetermined combustion stop condition is satisfied when the vehicle is traveling, perform deceleration-period combustion stop control, and limit combustion restart triggered by a reduction in rotational speed of an internal combustion engine, during execution of the deceleration-period combustion stop control, and a motoring controller configured to control the rotational drive of the internal combustion engine by a motor during execution of the deceleration-period combustion stop control so that the rotational speed of the internal combustion engine is maintained at a predetermined rotational speed during a period of time from the time that the rotational speed of the internal combustion engine decreases to the predetermined rotational speed until downshifting to a predetermined gear ratio is completed.

  • Patent number: 10576983
    Abstract: A vehicle system comprises a brake system comprising a brake pedal and a braking mechanism configured to apply a braking force to a vehicle, and a vehicle control unit operable to automatically stop an engine when the vehicle is decelerated to a given vehicle speed or less during traveling. When it is detected that the brake pedal is manipulated and the vehicle is stopped after automatically stopping the engine, the vehicle control unit is operable to control the braking mechanism to increase the braking force from a current value according to a manipulation amount of the brake pedal up to a given value.

  • Publication number: 20200049119
    Abstract: A vehicle control system comprises: a roof opening-closing button (12) provided inside a passenger compartment of a vehicle and configured to accept opening and closing manipulations for a roof unit (4); and a control unit (25) configured to control an engine (2), a roof actuator (10) of the roof unit, and an air conditioner (34), wherein the control unit is operable, when the roof opening-closing button accepts the closing manipulation for shifting the roof unit from an opened state to a closed state, in a situation where the roof unit is in the opened state, and the engine is in an idle-stop state, to control the engine such that the engine being in an idle-stop state is restarted, and control the roof actuator such that the roof unit being in the opened state is shifted to the closed state.
