摘要： In a vehicle control device for controlling the vehicle, when automatic downshift control for automatically downshifting a speed ratio of the transmission is executed in the case where a drive current value of the motor obtained when the second oil pump is driven is larger than a maximum value of the drive current value of the motor obtained when the second oil pump is driven in a normal drive state, the vehicle control device increases a minimum rotation speed of the drive source compared to a case where the drive current value of the motor is equal to or less than the maximum value, and when the automatic downshift control is executed in the case where a line pressure generated by a hydraulic pressure supplied from the first oil pump and the second oil pump is larger than a predetermined value, the vehicle control device does not increase the minimum rotation speed of the drive source even in the case where the drive current value of the motor obtained when the second oil pump is driven is larger than the maximum value.

摘要： Pressure regulation valve control device has line pressure regulation valve (4) having line pressure solenoid (41) and line pressure spool valve (42) and CVT control unit (8) controlling secondary pressure (Psec) by actuating the line pressure spool valve (42) by solenoid pressure (Psol) produced by controlling current command value (I) to the line pressure solenoid (41). CVT control unit (8) has abnormality control unit (81). The abnormality control unit (81) is configured to, when decrease in secondary pressure (Psec) is detected during travel, execute, during travel, abnormality control that increases solenoid pressure (Psol), supplied to line pressure spool valve (42) from line pressure solenoid (41), more than solenoid pressure (Psol) of a time when the decrease in secondary pressure (Psec) is detected. With this, even when the decrease in the pressure is detected during travel, the decrease in the pressure is suppressed during travel while reducing influence on vehicle travel.
