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

A vehicle control device for controlling a vehicle that transmits a driving force received from an engine to a driving wheel via a continuously variable transmission mechanism including a pair of pulleys and an endless member wound around the pulleys, wherein

• in a case where an accelerator is in a non-depressed state during traveling, a second traveling state is established in which fuel supply to the engine is stopped and the engine is rotated by a driving force transmitted from the driving wheel to the engine,
• when the accelerator is depressed during traveling in the second traveling state, the fuel supply to the engine is restarted, and a hydraulic pressure supplied to the pulleys is increased,
• in a case where the accelerator is in a non-depressed state during traveling and a prescribed condition is satisfied, a first traveling state is established in which the fuel supply to the engine is stopped and a clutch between the engine and the driving wheel is disengaged,
• when the accelerator is depressed during traveling in the first traveling state, the engine is started and the clutch is engaged to increase the hydraulic pressure supplied to the pulleys, and
• a timing at which the hydraulic pressure supplied to the pulleys becomes higher due to the accelerator being depressed during traveling in the first traveling state is later than a timing at which the hydraulic pressure supplied to the pulleys becomes higher due to the accelerator being further depressed during traveling in the second traveling state.
