CONTROL APPARATUS FOR VEHICLE

摘要

A control apparatus for a vehicle provided with an internal combustion engine, an oil pump actuated by said engine for pressurizing operation oil, and a belt-type continuously variable transmission to which the operation oil pressurized by said oil pump is supplied, is provided. A transmission control is performed by controlling an operation oil pressure supplied to said continuously variable transmission, and an automatic stop of said engine is performed when a predetermined condition is satisfied. A transmission ratio of said continuously variable transmission is detected, and a continuable time period of the automatic stop of said engine is set according to the detected transmission ratio upon automatically stopping said engine. The automatic stop of said engine is controlled to end when a continuation time period of the automatic stop of said engine reaches the continuable time period. Good vehicle start performance can be obtained when restarting the engine after the automatic stop, regardless of the brake operation manner and the like upon stopping the vehicle.
