ABSTRACT:
An ECU executes a program including detecting an engine speed; detecting a turbine speed; calculating a slip revolution speed of a torque converter as; calculating a hydraulic pressure control value based on the slip revolution speed and a map; and outputting a hydraulic pressure control signal to a linear solenoid. The map is set such that the hydraulic pressure control value is smaller as the slip revolution speed increases in positive values.
