Title:
CONTROL DEVICE OF VEHICLE
Document Type and Number:
Japanese Patent JP2015209915
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To properly reduce a loss of a stepless gear change mechanism at idling.SOLUTION: When a power transmission route of a power transmission device 16 is used as a second power transmission route, a continuously variable transmission 24 is controlled at a gear change ratio γ at a high vehicle speed side more in the case that an input shaft angle acceleration dωi/dt is small than in the case that the input shaft angle acceleration is large, and thereby the gear change ratio γ of the continuously variable transmission 24 when the power transmission route is used as the second power transmission route can be controlled to the gear change ratio γ in which an inertia loss Tli of the continuously variable transmission 24 which changes according to the input shaft angle acceleration dωi/dt is taken into consideration. Accordingly, in a vehicle 10 in which the continuously variable transmission 24 and a gear mechanism 28 are arranged between an input shaft 22 and an output shaft 30 in a parallel with each other, a loss of the continuously variable transmission 24 at idling can be properly reduced.
