Classification: CPC F  B  Y | IPC B  F

Claim 0:
1. A controller for a vehicle, the vehicle comprising:
an internal combustion engine;
a motor generator;
a drive sprocket fixed to a crankshaft of the internal combustion engine;
an idler sprocket to which a driving force is transmitted from the drive sprocket;
a chain running around the drive sprocket and the idler sprocket;
a swing guide supported in a swingable manner;
a chain tensioner that pushes the swing guide against the chain; and
an oil pump that discharges oil when the crankshaft rotates, wherein
the controller is configured to control a traveling mode of the vehicle in a Battery Electric Vehicle mode that stops the internal combustion engine and drives the motor generator when the vehicle travels or a non-BEV mode that drives the internal combustion engine when the vehicle travels,
the chain tensioner has an oil damper functionality that uses oil supplied from the oil pump, and
when shifting the traveling mode of the vehicle from the BEV mode to the non-BEV mode, the controller is configured to execute a high-pressure process for controlling the oil pump such that a supply pressure of oil supplied to the chain tensioner becomes higher when a duration of the BEV mode is greater than or equal to a specified time than when the BEV mode duration is less than the specified time.
