Automotive Collision Avoidance Control System Research

In this paper, it is presented a sort of Automotive Braking Anti-shock System, based on the analysis of internal and overseas Automotive Anti-shock Technology and the current development actuality of internal Automotive Anti-shock Active-Safety technology. There are two working modes: "Automotive Braking mode" and "cruising mode". In order to achieve the Automotive Braking Anti-shock control, the Automotive Braking mode acts as a directly control system by "two-step alarms and automatic brake" control strategy, while the cruising mode indirectly by "constant velocity" control strategy.Firstly, focus on the Automotive Braking mode, the presented scheme can achieve the Anti-shock control of system. Based on this scheme, a method of safety-model is established and an automotive safety decision is discussed in detail. A sort of executive-framework which can finish automatic braking is designed, while guaranteeing the original automotive braking operation as normal. Considering the Road Surface Recognizing technology which has not been formed accordant theory till now, the Road Surface Recognizing technology is achieved by computer interface through the road material and its surface situation from the driver. In order to decrease the system Inveracious Alarm, the alarm restraining can be done when the driver turn about, loose accelerograph and apply the brake.Secondly, focus on the cruising mode, the proposed scheme can achieve the "constant velocity" control. In this scheme, we establish the automotive emulation mode and select increased-PID control method. Through the simulation by Matlab/simulink software, the cruising mode can completely achieve the automotive running in constant velocity control mode.Finally, the hardware circuit is designed for the Automotive Braking Anti-shock System by PROTEL DXP drawing, as well as the system software is completed.Automotive Anti-shock System which is studied can afford one effective approach to reduce fore-and-aft traffic accident and accord with intelligent trend of internal and overseas vehicle development. Furthermore, the system will offer a theory base of the follow-up development and production. In a word, the application of this system will have a good prospect of application and economy.
