Title:
A power transmission device for vehicles
Document Type and Number:
Japanese Patent JP5945068
Kind Code:
B2
Abstract:
A vehicular power transmission including a crank type continuously variable transmission is provided in which when the rotational speed of an engine during deceleration fuel cut-off is at least a first rotational speed, which is an upper limit of rotational speed at which plunging of a starter motor is possible, but less than a second rotational speed, which is a lower limit of rotational speed at which self-ignition of the engine is possible. The engine is cranked and restarted by transmitting the driving force of an electric motor of a shift actuator to an input shaft via first and second engagement portions. This eliminates the need for restarting the engine with the starter motor by waiting until the rotational speed of the engine has become less than the first rotational speed, thus reducing the time required for restarting the engine. Moreover, the electric motor can be made small.
