Abstract
A control device for a vehicle having: an engine; and a variator arranged downstream of the engine in a power transmission path connecting the engine and drive wheels, wherein the control device for the vehicle has a controller that executes a low standby control which downshifts the variator by moving a belt of the variator in a vertical direction (radial direction) during stopping of the vehicle. After starting the low standby control, the controller releases an output limit of the engine based on an actual secondary pressure of the variator.
Claims4
A control device for a vehicle having:
- a driving source;
- and
- a belt continuously variable transmission mechanism that is arranged downstream of the driving source in a power transmission path connecting the driving source and drive wheels,
- the control device comprising:
- a controller configured to execute a low standby control which downshifts the belt continuously variable transmission mechanism by moving a belt of the belt continuously variable transmission mechanism in a radial direction during stopping of the vehicle,
- wherein the controller is configured to release an output limit of the driving source based on an actual pressure of a secondary pulley hydraulic pressure of the belt continuously variable transmission mechanism after starting the low standby control when an increase rate of the actual pressure of the secondary pulley hydraulic pressure of the belt continuously variable transmission mechanism becomes greater than or equal to a predetermined rate.
