Title:
CONTINUOUSLY VARIABLE TRANSMISSION FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2012/111364
Kind Code:
A1
Abstract:
[Problem] To achieve a configuration of a continuously variable transmission for a vehicle which is capable of preventing the vehicle from continuing to travel at high speed in the opposite direction to the driver's intended direction when the shift lever is moved into a selection position that is in the opposite direction to the current travel direction while the vehicle is traveling. [Solution] When the traveling speed of a vehicle, which is traveling in a state in which the shift lever has been moved into a selection position that is opposite in direction to the current travel direction, is faster than a predetermined speed (V1), a clutch device that transmits power between a continuously variable transmission and a differential mechanism is cut off, preventing any further driving force of a drive source from being transmitted to the wheels. As a result, even if the driver steps on the accelerator pedal in an attempt to travel faster in the opposite direction, or with the intention of accelerating in the opposite direction, the vehicle is slowed down without accelerating, preventing the vehicle from continuing to travel at high speed in the opposite direction to the driver's intended direction.
