A vehicle control system configured to judge a vehicle behavior or a driving preference of a driver based on acceleration of the vehicle including at least longitudinal acceleration. An acceleration value used in the judgment is obtained on the basis of a weighted detection value of the actual longitudinal acceleration of the vehicle, and a weighted parameter which is varied by an operation to increase a driving force of the vehicle executed by the driver. A weight on the parameter is reduced in case a weight on the detection value of the longitudinal acceleration is increased, and the weight on the parameter is increased in case the weight on the detection value of the longitudinal acceleration is reduced.
