  • Publication number: 20170328331
    Abstract: In a system for controlling rotation of torque applied to a rotating shaft of an engine of a vehicle that uses the engine as a drive source thereof, a motor is provided. A main controller controls the engine and the motor. The main controller selectably activates the motor that applies first torque to the rotating shaft of the engine, and deactivates the motor. A rotary electric machine includes a rotor connected to the rotating shaft of the engine. A rotation parameter detector measures a rotation parameter associated with rotation of the rotor of the rotary electric machine. A sequence controller performs, in response to an occurrence of a trigger situation, a control sequence that controls, independently of the main controller, the rotary electric machine based on the rotation parameter measured by the rotation parameter detector, thus applying second torque to the rotating shaft of the engine.

  • Publication number: 20170328328
    Abstract: An apparatus for starting an engine, including a motor, an output shaft driven by the motor, a pinion provided along the output shaft, and an electro-magnetic solenoid device. The electro-magnetic solenoid device is configured to push the pinion axially toward a ring gear of the engine to mesh the pinion with the ring gear and transfer a rotational force, which is referred to as a motor torque, generated by energization of the motor from the pinion to the ring gear, thereby starting the engine. The apparatus is configured such that, at starting of the engine in its warmed-up state, the motor torque can continue to be applied from the pinion to the ring gear until at least the second compression stroke even when an engine speed varies.
