Abstract: A driving system for a vehicle includes a drive source, a driven portion, a wet multiple disc connection/disconnection unit provided on a power transmission path between the drive source and the driven portion, and a connection/disconnection unit controller configured to control a release and an application of the connection/disconnection unit, wherein the driving system further includes a time counter configured to obtain a continuous applied time that is an elapsed time from a start of a latest application of the connection/disconnection unit.

Abstract: A driving system for a vehicle includes drive source, a driven portion, a unidirectional power transmitting unit provided on a power transmission path between the drive source and the driven portion, and having a first member, a second member, and an engaging element interposed between the first member and the second member, and an eccentricity acquiring unit adapted to acquire an eccentricity, the eccentricity being a magnitude of deviation between the rotational axis of the first member and the rotational axis of the second member.

Abstract: An engine starting apparatus includes a starter motor rotating when the engine is started, a wedge roller speed reduction mechanism adapted to output a rotation of the starter motor from an output shaft at a reduced speed and to cut off power transmission between the starter motor and the output shaft when the rotational speed of the output shaft exceeds the reduced speed, a pinion gear provided on the output shaft in such a manner as to rotate together with the output shaft and to move axially over the output shaft between an engagement position where the drive gear is mesh engaged with a ring gear and a disengagement position where the pinion gear is disengaged with the ring gear, and a magnet switch for driving the pinion gear to the engagement position when the engine is started and to the disengagement position after the engine has been started.
