Abstract
A vehicle control system and method is applied to a vehicle including: a continuously variable transmission for changing a speed ratio continuously that is disposed between an input shaft and an output shaft; a geared transmission that is disposed parallel to the continuously variable transmission, and that is adapted to establish a speed ratio that cannot be established by the continuously variable transmission; and a friction clutch that is brought into engagement to switch a torque transmission route from a route including the geared transmission to a route including the continuously variable transmission. The vehicle control system is configured to start a speed change operation of the continuously variable transmission before a commencement of clutch-to-clutch shifting between the friction clutches when switching the torque transmission route from the route including the geared transmission to the route including the continuously variable transmission.
