Description

The small electric vehicle which is mounted “in-wheel motor” as one of the solutions of the single-passenger car is shown. Driver’s operating performance on driving vehicle is limited in emergency conditions. Therefore, it is important to set up active safety technology geared to the collision avoidance is based in the micro-car, especially. One measure to reduce accidents is an automatic collision avoidance system using automatic steering control. This research proposes an automatic steering system for collision avoidance by a steered vehicle called the ‘Active Torque Steering system (ATS)’. The purpose of this research is to clarify the automatic steering ability of the ATS vehicle by comparing it with that of an AFS function (Active Front Steering function) and a DYC function (Direct Yaw moment Control function) through simulations using the time history response and tire forces evaluation.
