a starter including a motor that generates rotational force, a pinion that receives the rotational force of the motor to rotate, a motor energization unit that turns on and off power supply from a battery to the motor, and a pinion pushing unit that pushes the pinion toward a ring gear of an engine to mesh with the ring gear; and a starter control unit configured to control driving of the starter, the starter control unit being configured to operate the motor with the pinion engaged with the ring gear to thereby crank the engine, and de-engage the pinion from the ring gear or de-energize the motor to thereby terminate the cranking of the engine, wherein a cranking time from when cranking of the engine is initiated to when a predetermined engine speed equal to or greater than 450 rpm is reached is equal to or less than an acceptable limit of cranking time that does not provide, to a user of a vehicle, noticeable discomfort caused by cranking noise generated during the cranking of the engine. |
