A control device for a vehicle, the vehicle including a belt continuously variable transmission including a mechanical oil pump driven by an engine and an electric oil pump driven by an electric motor, the engine being configured to drive a drive wheel, in which when a rotation speed of the engine is less than or equal to a prescribed rotation speed as the vehicle decelerates, driving of the electric motor is controlled to supply a hydraulic pressure from the electric oil pump to the belt continuously variable transmission, and when the deceleration of the vehicle exceeds a prescribed deceleration, the driving of the electric motor is restricted not to supply the hydraulic pressure from the electric oil pump to the belt continuously variable transmission.

Control device for vehicle, control method for vehicle, and non-transitory computer-readable medium

A continuously variable transmission includes: a first pulley and a second pulley each including a fixed pulley and a movable pulley; and an endless member wound around the first pulley and the second pulley, wherein the continuously variable transmission continuously changes a speed ratio by controlling a thrust of the movable pulley with a hydraulic pressure, the thrust of the movable pulley is made smaller as a rotation speed of the first pulley decreases, and when the rotation speed of the first pulley is lower than a predetermined rotation speed, the thrust of the movable pulley in a case where the speed ratio is on a Low side of the predetermined speed ratio is not made smaller than the thrust of the movable pulley in a case where the speed ratio is on a High side of the predetermined speed ratio.

Continuously variable transmission, method for controlling continuously variable transmission, and non-transitory computer-readable medium

Provided is a control device for a vehicle including a first oil pump that is driven by a first drive source driving a drive wheel of a vehicle and configured to supply oil to a hydraulic pressure actuation machine, and a second oil pump that is driven by a second drive source different from the first drive source and configured to supply oil to the hydraulic pressure actuation machine. The control device drives the second oil pump when a start switch of the vehicle is turned on and the first drive source is started for the first time, and drives the second oil pump when the second oil pump is not driven for a first predetermined time after the first drive source is started, and a rotation speed of the second oil pump when the first drive source is started is lower than a rotation speed of the second oil pump after the first drive source is started.

A fixed conical plate that is fixed to a rotation shaft, a movable conical plate that moves in the axial direction of the rotation shaft with respect to the fixed conical plate, a slide mechanism that moves the movable conical plate, and a controller that controls the state of the slide mechanism are provided. The controller changes the groove width of a second pulley by driving a motor generator, while a first clutch is engaged, and thus moving the movable conical plate, and drives the motor generator as a generator by the rotation of the rotation shaft, by engaging a second clutch.
