Abstract:
1. A vehicle control system, comprising: road surface reaction torque detecting means for detecting an actual road surface reaction torque received by a tire of the vehicle from a road surface; steering angle detecting means for detecting a steering angle of a handle of the vehicle; vehicle speed detecting means for detecting a vehicle speed of the vehicle; reference road surface reaction torque computing means for computing a reference road surface reaction torque corresponding to a linear road surface reaction torque based on the steering angle and the vehicle speed; behavior state estimating means for 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 and the reference road surface reaction torque; and driving force control means for controlling a driving force of the vehicle according to the behavior state, wherein the road surface reaction torque detecting means is operative to detect an actual torque without input from a yaw rate detecting unit, and a front wheel slip angle estimating unit.
