Stability Criteria and Objective Evaluation of a Driver-Vehicle System for Driving in Lane Change and against Crosswind

Stability criteria of driver-vehicle system is derived analytically in typical cases of lane change and straight running against crosswind, assuming that vehicle dynamics are provided as a closed loop system and driver’s steering is controlled under a linear preview strategy. On the u(velocity)-Tp(preview time) plane, vehicle design parameters and driver’s characteristics can be discussed quantitatively in terms of the effects on the performance index J for good feeling and active safety.
