  • Patent number: 11110872
    Abstract: A power control device for a power supply mounted on a vehicle is provided, which includes a generator mounted on the vehicle and configured to regenerate power from kinetic energy of the vehicle, a high-voltage battery configured to accumulate the power regenerated by the generator, a low-voltage battery of which a nominal voltage is lower than the high-voltage battery, a voltage converter configured to lower an output voltage from the high-voltage battery and charge the low-voltage battery at the lower voltage, and a controller configured to control the voltage converter. The controller operates the voltage converter to start the charging of the low-voltage battery after the vehicle is powered ON and before an engine mounted on the vehicle is started.

  • 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.

  • 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.
