Abstract
A SSM(Sensor Steering Mechanism) vehicle achieved high-speed moving on a straight-line and high accuracy following the guideway of the road. The previous paper proposed the variable lever ratio (the ratio of the arm angle and the steering angle) and steering ratio (the arm length ratio based on the wheel base) in order to increase the moving speed by the generated trajectory. The SSM vehicle reduces the slip angle of the tires at the corner of the course, and the moving speed of the SSM vehicle is increased. This study estimates the lateral control characteristics of the SSM vehicle with 1kHz smart camera which is moving on S-curves. The S-curves are set the turning angles 45o and 90o for the test course. Finally, the simulated results show the advantages of the variable SSM.
