Abstract: | An AWS (all-wheel-steering) system is applied to the articulated vehicle to satisfy the required steering performance. AWS
ECU (electronic control unit) controls the hydraulic actuator according to vehicle driving environment, such as driver steering
angle, articulating angle, and vehicle velocity. In this paper, the test platform devloped for the AWS ECU black box test
in an HIL( hardware in the loop) environment is explained. Using the developed test platform, the control algorithm of the
AWS ECU can be evaluated under the virtual driving condition of the articulated vehicle. Also, the maneuver of the vehicle
is investigated by using the developed AWS ECU test.
This paper was presented at the 4th Asian Conference on Multibody Dynamics(ACMD2008), Jeju, Korea, August 20–23, 2008.
Sooho Lee received a B.S. degree in Mechanical Engineering from Ajou University in 2003. He then went on to receive his M.S. degree
from Ajou University in 2005. Mr. Lee is currently a Ph.D student in the School of Mechanical Engineering at Ajou University
in Suwon, Korea. His research interests are in the area of dynamics, vehicle dynamics, control and HILS ( hardware in the
loop simulation). |
