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 S310 and S380), 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 S300). 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.
Claims20
A vehicle, comprising:
- a driving power source that outputs power to a power shaft;
- a motor that inputs and outputs power into and from the power shaft;
- a transmission that enables transmission of power with a change of a speed between the power shaft and an axle and disconnection of the power shaft from the axle;
- and
- a controller that controls the transmission to connect the power shaft with the axle with restriction of rotation of the power shaft by at least one of the driving power source and the motor, in response to a change of a gearshift position from a parking position to a driving position.
