Provided is a unit including: a housing configured to accommodate a differential gear mechanism, in which the housing has a flow path through which a coolant flows, the flow path has a portion that overlaps the differential gear mechanism when viewed in a radial direction, and the flow path has a portion that is positioned above a horizontal plane passing through an axis of an output shaft of the differential gear mechanism and orthogonal to a gravity direction.

Unit

Provided is a unit including: a heat exchanger; a housing configured to accommodate a power transmission mechanism; and a covering having a portion that covers the housing, in which the heat exchanger has a portion offset from the covering when viewed in a radial direction, and the heat exchanger has a portion that overlaps the covering when viewed in the radial direction.

A controller changes a shift line of the continuously variable transmission to a high rotation side when execution of automatic brake is detected during sailing stop which stops the engine while driving the vehicle.

Control device and control method for vehicle including continuously variable transmission

A control device for a vehicle is provided, which vehicle includes a driving source, a driven machine driven by the driving source, and an automatic transmission having a torque converter provided downstream of the driving source in a power transmission path and having a lockup clutch, and an engaging element provided downstream of the torque converter in the power transmission path. The device includes a control unit adapted to engage the engaging element in a state where the lockup clutch is engaged if a brake pedal is stepped on during neutral running control in which the automatic transmission is brought into a power shut-off state during running of the vehicle.

Control device for vehicle and control method for vehicle

A control device for a vehicle is provided, which vehicle includes a driving source, and an automatic transmission having a torque converter provided downstream of the driving source in a power transmission path and having a lockup clutch, and an engaging element provided downstream of the torque converter in the power transmission path. The device includes a control unit which engages the engaging element in a state where the lockup clutch is engaged if an accelerator opening becomes not smaller than a predetermined opening during neutral running control in which the automatic transmission is brought into a power shut-off state during running of the vehicle.

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.

A control device of controlling a vehicle that includes an automatic transmission is provided with a control unit. The automatic transmission includes a power transmission mechanism with an engaging element, and a variator connected in series to the power transmission mechanism. The control unit of this device completes engagement of the engaging element after downshifting of the variator is completed when at least an accelerator pedal opening becomes not smaller than a predetermined opening, during neutral running control which brings the power transmission mechanism into a power shut-off state during running of the vehicle.

Control device for vehicle and control method of the same

A vehicle control device for controlling a vehicle includes a drive source and an automatic transmission connected to the drive source and including a variator. The vehicle control device includes: a first control unit configured to execute a during-travel drive source stop control for stopping the drive source and shifting the automatic transmission in a neutral state if a during-travel drive source stop condition is satisfied; and a second control unit configured to execute a during-travel drive source stop release control for shifting the automatic transmission in a power transmission state via a rotation synchronization control in the automatic transmission set in the neutral state if a during-travel drive source stop release condition is satisfied. The second control unit executes the rotation synchronization control with the variator downshifted from a speed ratio during the during-travel drive source stop control if the during-travel drive source stop release condition accompanied by a downshifting request of the variator is satisfied.

Vehicle control device and vehicle control method

A control device for a vehicle controlling the vehicle including a driving source and an automatic transmission coupled to the driving source and includes a power transmission mechanism including a forward engaging element. The control device for the vehicle includes a first control unit configured to execute a driving-source-stop-while-traveling control that stops the driving source and brings the automatic transmission into a neutral state when a driving-source-stop-while-traveling condition for stopping the driving source while traveling is satisfied and a second control unit configured to engage the forward engaging element on the basis of input and output rotation speeds of the power transmission mechanism after a driving-source-stop-while-traveling cancellation condition is satisfied.

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.
