Abstract
In this report, I will discuss the target vehicle dynamics in low speed region. We discuss the effects which variation between body slip angle and yaw velocity affects driver’s sensitivity or evaluation in the low speed cornering situation. Firstly maneuverability test for low speed cornering was examined by front and rear steering vehicle. The result says that the driver can control without discomfort for the higher yaw velocity gain, the smaller outward body slip angle is generated at the low speed cornering. Next I will explain the characteristics by the analysis of the driver-vehicle closed loop system. I assumed that driver recognizes the angle between vehicle heading direction and gaze point as the gaze angle and steers based on the first order look-ahead driver model. Consequently the discussion about the gain of the driver model in the human-vehicle closed loop system revealed that the effect which variation between body slip angle and yaw velocity affects driver’s sensitivity or evaluation for vehicle cornering motion.
