In this paper, the auxiliary brake system vehicle stability control experiments using Mat lab/Simulink to build the simulation system dynamics associated auxiliary braking system and the actual vehicle system. In the trajectory of the vehicle and the vehicle sideslip angle characterizing the vehicle condition, using the integrated stability control braking and driving strategies, respectively, the actual vehicle system and test system with an auxiliary braking system in two test conditions under stability control performance analysis and validation. And then to verify the validity of the secondary braking system of the vehicle stability control, and in the absence of control or ESP control system failure can effectively assist the vehicle; and when the ESP control system with the performance of the actual vehicle stability control system in both test conditions have remarkable consistency. At the same time, the auxiliary braking system as a car with stability control test device is designed scientific and feasible.

Morphological matrix method and its key legal point of view the main function of the program from portfolio analysis, and then the combination of a good program to list, due to the combination of a lot of the number of programs, and therefore difficult to compare them one by one evaluation, it is difficult to get the best program. The main problem lies in the expert system knowledge acquisition and reasoning more difficult. Intelligent design of the car's mechanical system is actually an instance of reasoning and matching process. In this paper, automotive Intelligent Design System Based on CBR and RBR in an attempt to improve the efficiency of product design. ICAD system technology and artificial intelligence expert system optimization design, finite element analysis, computer graphics and other various numerical calculation methods combine their respective merits, complement each other, the aim is to make the computer as much as possible to participate in decision-making, structural design, performance analysis, graphics and so the whole process.
