Claim:
1. A vehicle control system comprising: a continuously variable transmission for changing a speed ratio continuously that is disposed between an input shaft to which torque of a prime mover is applied 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 is larger than a maximum speed ratio established by the continuously variable transmission; a first friction clutch that is brought into engagement during propelling the vehicle by delivering torque through a route including the geared transmission and brought into disengagement during propelling the vehicle by delivering torque through a route including the continuously variable transmission; and a second friction clutch that is brought into engagement during propelling the vehicle by delivering torque through the route including the continuously variable transmission and brought into disengagement during propelling the vehicle by delivering torque through the route including the geared transmission, wherein 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.
