Title:
VEHICLE POWER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/014750
Kind Code:
A1
Abstract:
Provided is a vehicle power transmission system which quickly performs shift operations in the transmission and is capable of alleviating the operator's discomfort due to so-called torque loss during said shift operations. This vehicle power transmission system (100) is provided with an engine (110) the operation of which is controlled by an ECU (300), a clutch (210) and a transmission (240). The engine (110) is provided with a bypass pathway (121) in a state in which a throttle valve (117) is bypassed by an intake pipe (116) which introduces a fuel-air mixture into a cylinder (111). An idle regulating valve (122) is provided in the bypass pathway (121). The idle regulating valve (122) regulates the amount of air that bypasses the throttle valve (117) and is supplied to the cylinder (111). The ECU (300) reduces the deceleration torque in the transmission (240) by opening the idle regulating valve (122) prior to shift change operations of the transmission (240).
