CONTROL DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To miniaturize an electric oil pump in a control device for a vehicle on which a continuously variable transmission capable of mechanically locking a primary pulley at the time of the maximum gear ratio is mounted and which can perform idle stop control.SOLUTION: A primary pulley of a continuously variable transmission is locked to the maximum gear ratio and idle stop control is performed (permitted) only when belt slip is suppressed by only supplying hydraulic pressure to a secondary pulley during engine restart. The idle stop control is not performed (electric oil pump stop) when it is necessary to supply hydraulic pressure to both the primary pulley and the secondary pulley. Such control eliminates the necessity for making the discharge flow rate of the electric oil pump secure the hydraulic pressure of both the primary pulley and the secondary pulley. Consequently, the electric oil pump can be miniaturized.
