ABSTRACT:
There is provided a control system for a vehicle, which is capable of increasing the service life of a transmission belt while preventing slippage thereof, and at the same time improving fuel economy and drivability. The control system for a vehicle sets a transmission transfer torque to be transmitted from a drive pulley of a continuously variable transmission to a driven pulley of the same, and a clutch transfer torque to be transferred by a clutch. When it is determined that the vehicle is traveling on a bad road, the clutch transfer torque is reduced, and the transmission transfer torque is set to a larger value as the clutch transfer torque is larger.
