애커만 경향이 차량 핸들링 성능에 미치는 영향 고찰

This paper descries design parameters of Ackerman steering geometry influencing on vehicle handling performances. It is assumed that the Ackerman steering geometry should be designed by considering tire characteristics especially regarding lateral force and these design parameters are related to a performance limit, response, and traceability. The test design plan consists of three conditions: turning concentric circle test, step steer test, and double lane changes. These test conditions follow ISO or test standard of Hyundai Motor Company. The influence of the proposed assumption has been verified by using computer simulation.
