THE DEVELOPMENT OF A TEST PLATFORM FOR AWS (ALL WHEEL STEERING) ECU (ELECTRONIC CONTROL UNIT) OF THE BI-MODAL TRAM

초록

An AWS (All-Wheel-Steering) system is applied to the bi-modal tram to satisfy the required steering performance because the bi-modal tram has extended wheel base and articulated chassis. AWS ECU controls 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 a 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 bi-modal tram. Also, the maneuver of the vehicle is investigated using the developed AWS algorithm.
