Abstract
Provided is a vehicle control system which can maintain stability of the vehicle with an inexpensive configuration without bringing discomfort to a driver when control intervenes. The vehicle control system includes: road surface reaction torque detecting meansfor detecting an actual road surface reaction torque Talign received by a tireof the vehicle from a road surface; steering angle detecting meansfor detecting a steering angle θ of a handleof the vehicle; vehicle speed detecting meansfor detecting a vehicle speed V of the vehicle; reference road surface reaction torque computing meansfor computing a reference road surface reaction torque Tref corresponding to a linear road surface reaction torque based on the steering angle θ and the vehicle speed V; behavior state estimating meansfor estimating a behavior state of the vehicle based on at least one of a deviation and a ratio between the actual road surface reaction torque Talign and the reference road surface reaction torque Tref; and driving force control meansfor controlling a driving force of the vehicle according to the behavior state.
