A vehicle control system configured to carry out an energy saving control is provided. The vehicle control system is applied to a vehicle having an engine, a torque converter, a transmission and a clutch device selectively connecting a turbine runner to the transmission. The vehicle control system executes the energy saving control by controlling both an operating condition of the engine and an engagement condition of the clutch device or only the engagement condition of the clutch device. The vehicle control system comprises a clutch control means configured to increase the torque transmitting capacity of the clutch device using an increasing amount of a speed of the turbine runner as a target value, when bringing the clutch device into engagement being in disengagement during execution of the energy saving control.
