Title:
TORQUE CONTROL DEVICE OF DRIVING SOURCE
Document Type and Number:
WIPO Patent Application WO/2012/124626
Kind Code:
A1
Abstract:
A vehicle driving apparatus (100) comprises: driving sources (1, 2); an input shaft (7) configured to be rotated by driving forces transmitted from the driving sources (1, 2); a continuously variable transmission mechanism (30) for transmitting rotation of the input shaft (7) to an output shaft (10) while changing the speed of the rotation; and a start clutch (11) for switching to a mode for transmitting power from the output shaft (10) to a downstream side. If a ratio (R) of the continuously variable transmission mechanism (30) is lower than a predetermined threshold value (R1), output torque control means (50, 51, 52) for controlling output torque of the driving sources (1, 2) is operated to limit an upper limit (TQmax) of the output torque of the driving sources (1, 2) to a value lower than an upper limit (TQmax) when the ratio (R) is higher than the threshold value (R1). In this way, load accumulation on the start clutch is suppressed to improve both the vibration prevention ability and power performance of a vehicle.
