摘要： A vehicle control device is for a vehicle having a drive source, and an automatic transmission connected to the drive source, the automatic transmission having an engagement element for disconnecting/connecting transmission of a driving force and a variator placed further upstream than the engagement element. The vehicle control device includes first and second control units. The first control unit is configured to execute sailing stop control to stop the drive source and to put the automatic transmission into a neutral state when a sailing stop condition is established. The second control unit is configured to start the drive source and to implement downshifting of the variator when a size of a deceleration level is a prescribed value or greater when the sailing stop control is cancelled due to a prescribed sailing stop cancellation condition among sailing stop cancellation conditions being established, and to engage the engagement element after the downshifting.

摘要： The power supply device includes a low voltage battery, a high voltage battery, a starter generator, a DC-DC converter, a changeover switch, and a controller. When an abnormality or a failure has occurred in the DC-DC converter, the controller controls the changeover switch to connect the starter generator to the other battery without via the DC-DC converter and controls the output of the starter generator corresponding to the connected other battery.

摘要： A transmission controller gives an engagement instruction to a forward clutch so that the forward clutch is engaged when a rotation speed of the engine becomes a target engine rotation speed set on the basis at least of a vehicle speed and a speed ratio of a continuously variable transmission after the engine is started, if a cancellation request for a sailing-stop control is made during execution of the sailing-stop control, and the continuously variable transmission is downshifted before the forward clutch is engaged, if the target engine rotation speed when the cancellation request for the sailing-stop control is made is less than a first predetermined value.

摘要： A controller is a control device for a vehicle including an engine, an automatic transmission, and an oil pump and executes a sailing stop control that stops the engine and brings the automatic transmission into a neutral state when a sailing stop condition is satisfied. The controller cancels the sailing stop control to start the engine when a road inclination becomes larger than a predetermined value during the sailing stop control.

摘要： A control device for a vehicle includes a drive shaft, an engine coupled to the drive shaft, an electric motor coupled to the drive shaft, and a control unit. The control unit increases a torque of the electric motor when an accelerator pedal opening increases to equal to or more than a predetermined degree of opening during switching of driving sources, and decreases the torque of the electric motor while increasing the torque of the engine after a change of the torque of the engine turns to increase.
