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.

Driving system for vehicle

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.

In a drive controller for a vehicle including: a drive source configured to output a drive force to a first axle serving as one of front and rear wheel axles; an electric motor configured to output a drive force to a second axle serving as the other of the front and rear wheel axles; a one-way power transmission device disposed on a power transmission pathway between the second axle and the electric motor so as to transmit a power drive force from the electric motor to the second axle; a two-way power transmission device that transmits a rotation power from the second axle to the electric motor or transmits the power drive force and a regeneration drive force from the electric motor to the second axle, the drive controller includes: a first detector that detects a speed of the vehicle or a rotation speed of the second axle; a target rotation speed determination section that determines a target rotation speed of the electric motor based on the speed of the vehicle or the rotation speed of the second axle; a second detector that detects a rotation speed of the electric motor; and a controller that controls the electric motor such that the rotation speed of the electric motor is synchronized with the target rotation speed and that controls an output torque of the electric motor or an activation of the two-way power transmission device, when the electric motor starts power drive or regeneration drive while the vehicle is traveling by the drive force from the drive source.

Drive controller for vehicle

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.
