Performance of Driver-Vehicle System in Emergency Avoidance

By means of a new test method for simulating automotive accidents on ordinary roads, we found that while both experienced and inexperienced drivers have the same initial steer input to avoid an unexpected obstacle, experienced drivers display more stable performance in the subsequent control of the vehicle.

Further, utilizing driver's transfer functions we studied a mathematical simulation of test results and obtained parameters for both experienced and inexperienced drivers.

These indicate that when vehicle yaw response is greatly delayed, inexperienced drivers may lose control, while experienced drivers will secure control of the vehicle.
