: All-wheel steering (AWS) system is applied to articulated vehicles to reduce turning radius. The swing-out suppression algorithm is applied to AWS ECU, a key component of AWS system. The swing-out suppression algorithm applied to AWS ECU has a problem when velocity of vehicle is changed. In this paper, new algorithm based on moving distance that solve velocity problem is proposed. The HILS simulation and the test articulated bus is used to validate algorithm.

This paper suggests that implementation of the Simulink execution module controls Simulink simulation and shows simulation results by applying Automata theory. This module is composed of three independent systems that the main program to accept user commands, the thread to control a simulation of Simulink model and the Simulink model to execute simulation. This paper designs each module and entire system by applying Automata theory, and implements it with C# and MATLAB language. And the Simulink execution module implemented will be verified through the experiment.
