Abstract
In setting of an oil temperature increasing process mode, the drive control technique of the invention starts an engine to actuate a mechanical oil pump that pressure feeds a flow of lubricating oil for lubricating the mechanical parts of a transmission and other relevant parts, actuates an electric oil pump that pressure feeds the flow of lubricating oil, and makes a brake Bincluded in the transmission in a semi-engagement state. A motor arranged adjacent to the transmission is then driven with lowered output efficiency. This arrangement effectively accelerates heat generation by the motor and ensures a quick temperature rise of the lubricating oil.
