Handling Safety Evaluation of Driver-Vehicle Closed-Loop System with Random Road Input

The response simulation is studied and the handling sa fety is evaluated using finer integration method for driver-vehicle closed-loop system with steady random road input. This algorithm is not only accarate, but a l so can shorten the evaluation period of handling safety and reduce the tremendou s cost for real vehicle testing. The response simulation and the vehicle handlin g safety evaluation are also studied for the closed-loop system with evolutionar y random road input. The study can more truly evaluate vehicle driving for inclu ding the slow variation of vehicle velocity with time.
