The effectiveness of refined ABS control logic is proved to match the original product by results obtained in the vehicle field tests by the two controllers mentioned above. Furthermore, the most advanced vehicle control system, ., vehicle stability control system is studied by using the extended ABS rapid development system. By the direct yaw moment control by regulation of braking forces, the vehicle dynamic stability may be improved. The controller makes the vehicle follow the desired dynamic model by feed forward regulation of side slip angle and the state feedback of both the yaw rate and side slip angle. By taking the Jturn and single lane change at the vehicle high speed, for example, the control law has been implemented by the extended ABS rapid development system. By the HiL realtime simulation results it is shown that the present control law is quite effective and robust in keeping the vehicle to follow the desired trajectories quickly and exactly even some parameters changing in the system, such as steering angle input, road friction and vehicle speed. It is demonstrated by theoretical and experimental results that the ABS rapid development system is an extended powerful tool for the development of vehicle electronic controllers. The realtime hardwareintheloop simulation technology is being increasingly important as a tool for the development of high level and quality vehicle electronic controllers with a lot of plexities and sophistication. In this paper, a rapid and economical development method for the vehicle ABS control system is presented and the development procedure of the vehicle ABS leads to faster development and more efficient parameter adjustment in parison with the invehicle development in the sense of development period and cost. The selfdeveloped control algorithm is testified through vehicle field tests, which is significant and satisfactory vehicle braking performance is observed. Successful application of both the rapid development procedure and the rapid development system established for the ABS control system development has shown that the present research supplies an efficient way to develop vehicle electronic system for local automotive industries.
