As illustrated in FIG. 2, during the drive of a motor vehicle, the opening degree of a throttle is held at 0% when the manipulated variable of an accelerator is equal to or less than a predetermined value .alpha. % near 0%, and the braking force of the vehicle is increased in accordance with the decrement of the manipulated accelerator variable based on .alpha. %. Thus, the requests of the driver of the vehicle for a driving force and for the braking force can be exactly detected from the manipulated accelerator variable, whereby the driver's intention is positively and distinctly reflected in the behavior or stability of the vehicle.

A hybrid vehicle includes an engine, motors configured to input and output power, a power distribution integration mechanism, and a transmission. The power distribution integration mechanism has a sun gear connected with one of the motors, a carrier connected with the other motor, and a ring gear connected with the engine. The transmission includes a first speed change mechanism and a second speed change mechanism. The first speed change mechanism has a first speed gear train and a third speed gear train arranged to connect the carrier of the power distribution integration mechanism with a driveshaft. The second speed change mechanism has a parallel shaft-type gear train that is not used alone to set the speed ratio.
