Title:
VEHICULAR POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/162815
Kind Code:
A1
Abstract:
In this vehicular power transmission device comprising a crank-type continuously variable transmission, if the rotation speed of an engine (E) during deceleration fuel cut-off is greater than or equal to a first rotation speed, which is the upper-limit rotation speed at which a starter motor (S) can jump in, and below a second rotation speed, which is the lower-limit rotation speed at which the engine (E) can self-ignite, the engine (E) is cranked and restarted by transmitting the drive force of an electric motor (24) of a speed-change actuator (23) to an input shaft (12) via first and second engagement parts (43a, 44a). Thus, there is no need to restart the engine (E) with the starter motor (S) by waiting until the rotation speed of the engine (E) falls below the first rotation speed, and the time required to restart the engine (E) can be shortened. Moreover, the electric motor (24) only needs to have an output that can raise the rotation speed of the engine (E), and thus, the electric motor (24) can be reduced in size.
