Abstract
In a motor vehicle having a planetary gear mechanism linked to an engine, a first motor, and a drive shaft and having a second motor attached to the drive shaft via a transmission, in a Lo gear position of the transmission, the control procedure of the invention drives the engine intermittently corresponding to a preset engine power demand Pe* (steps Sand S). In a Hi gear position of the transmission, the control procedure keeps the engine in load operation (step S). When a relatively large driving force is required in the Hi gear position of the transmission, the drive control of the invention enables quicker output of the required driving force to the drive shaft, compared with the output of the driving force from the operation stop state of the engine.
