Design and implementation of Lab. simulator for vehicle control

Abstract

Lab. simulator for conducting a performance test and a reliability test on a vehicle and components has been embodied. In order to control non-linear of a vehicle, a fuzzy control algorithm, a running mode tracking algorithm and a vehicle speed control algorithm were applied to the actuator control. The vehicle controller and servo controller functions were implemented; position control, the gear shift control depending upon the vehicle RPM, control with actuator by controlling the pneumatic servo valve, and measured data information such as a position, a velocity and an acceleration as obtained through operation by means of the second differentiator and controlled a position precisely. An experimental apparatus was consisted of a dynamometer and a vehicle, and the performance and durability of the controller was verified. The Lab. simulator was mounted onto the vehicle, and the position control test and a LAP mode tracking test were conducted. It was found that the response characteristic, the tracking capability and precision of the position control were so excellent.
