Abstract:
The response simulation is studied and the steering safety is
evaluated by using finer integration method for driver-vehicle
closed-loop system with stationary random road input. This
algorithm not only is precise, but also can shorten the
evaluation period of steering safety and reduce the tremendous
cost for real vehicle testing. The response simulation and the
vehicle steering safety evaluation are also studied for the
closed-loop system with evolutionary random road input. The
study can more truly evaluate vehicle driving for including the
slowly varying of vehicle velocity with time.
Key words: Closed-loop
