DRIVING DEVICE, MOTOR VEHICLE EQUIPPED WITH DRIVING DEVICE, AND CONTROL METHODS OF DRIVING DEVICE AND MOTOR VEHICLE

摘要

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 (step S100), actuates an electric oil pump that pressure feeds the flow of lubricating oil (step S110), and makes a brake B1 included in the transmission in a semi-engagement state (step S120). A motor arranged adjacent to the transmission is then driven with lowered output efficiency (steps S130 to S170). This arrangement effectively accelerates heat generation by the motor and ensures a quick temperature rise of the lubricating oil.
