Researches on the method of the hardware in loop simulation for vehicle stability control system based on scilab/scicos

Abstract

V process development method is generally used in the development of modern automotive electronics systems. The development process of ESC contains several steps as modeling, off-line simulation, hardware-in-loop testing and road test of vehicle. We build the vehicle dynamic model under scilab--an open-source scientific software, and make simulation in scicos. Then we construct the ESC hardware-in-loop testing system through communication between external interface of computer and digital IO board. Finally, we test the software/hardware system of ESC.
