Abstract:
1. A vehicle, comprising: an internal combustion engine; a motoring structure connected with an output shaft of the internal combustion engine and a rotating shaft and configured to perform a motoring of the internal combustion engine while outputting power to the rotating shaft; a motor that has a rotor connected with the rotating shaft and drives and rotates the rotor by a rotating magnetic field formed on a stator to input and output the power from and to the rotating shaft; an accumulator unit that transfers electric power to and from the motoring structure and the motor; a transmission unit configured to transmit power with a change in speed between the rotating shaft and an axle of the vehicle and to decouple the rotating shaft from the axle at least at a gearshift position set to a parking position; and a control module configured to, in response to a starting instruction of the internal combustion engine at a gearshift position set to a parking position, control the motor to fix a direction of a magnetic field formed on the stator with a level that is capable of restricting rotation of the rotating shaft against a shaft driving force defined as driving force applied to the rotating shaft within a driving force range set based on at least one of a state of a motor system including the motor and a state of the accumulator unit, control the motoring structure to perform a motoring of the internal combustion engine while outputting driving force that makes the shaft driving force within the driving force range, and control the internal combustion engine to be started with the motoring by the motoring structure.
