Crosswind Handling Performance for Driver-Vehicle System.

Lateral trajectory and crosswind sensitivity with fixed control steering are often applied in evaluating for crosswind conditions. These indices, however, don't always represent the delicate feeling on steering correction. In this paper, a stability criteria of driver-vehicle system is derived analytically for straight running against crosswind, and then the quadratic form of state variables for handling performance is proposed as an active crosswind sensitivity, in order to evaluate objectively handling performance against wind gust and to optimize many design parameters as well as aero-dynamics.
