Abstract
In response to a change of a gearshift position from a parking position to a driving position, the control system of the invention connects a power shaft with a driveshaft linked to drive wheels (steps Sand S), while performing rotation restriction control to form a fixed magnetic field on a stator of a second motor and thereby prohibit rotation of a rotor in the second motor (step S). This arrangement desirably restrains rotation of the power shaft and accordingly prevents the occurrence of a shock in the course of connection of the power shaft with an axle.
