A new optimal driver command interpreter for vehicle dynamics control

This paper introduces a new driver command interpreter (DCI) for vehicle control, providing the optimal calculation of desired C.G. forces and moments based on driver input commands and road conditions for the stability control system of vehicles. The proposed DCI is established based on the principles of optimal linear quadratic regulator (LQR) control theory and vehicle dynamics. The optimal feed-forward and feedback gains of the proposed DCI can be updated in real-time. Analytical simulations and experimental test results under a variety of driving conditions are presented to evaluate the proposed DCI. Simulations and test validations show that the proposed DCI can match the actual C.G forces/moment very well.
