Abstract: Automatic guided vehicle systems (AGVS) are key facilities in flexible integrated production and materialflow automation of the AGVS working performances. The stopping function at a given position, which is an obvious symbol to be different from other automatic vehicle, is very important in practical application. An intellectual braking control system was developed to make AGVS stop at a given position. Dynamic performance test and theoretical analysis were done for the braking control system．With the analysis of the system dynamic performance ,the software of date processing and real time controlling was developed.In the aspect of theoretical analysis, the mathematical model between the vehicle’s initial velocity and the moving distance is established under the action of the braking force. The control strategy of the braking system is proposed according to the relationship among the braking force, the initial velocity and the expected braking distance. In computer simulation, the research project conducted the dynamic simulation between the braking distance and vehicle’s initial velocity by the model established above when the braking force is zero.
