Research On Design And Control Strategy Optimization Of Automotive Automatic Emergency Braking System

In recent years,advanced driver assistance systems have gradually been equipped on the vehicles on the market,due to the rapid development of autonomous driving-related technologies.The L2-level assisted driving functions have brought convenience to the majority of drivers,and research on some of the safety guarantee functions has also gradually become a research hotspot.Great progress has been made on the autonomous emergency braking system(AEB,Autonomous Emergency Braking)as a safety driving assistance function.Furthermore,research is being conducted on the automatic emergency braking system of automobiles in combination with domestic new car evaluation standards and relevant national standards for intelligent connected vehicles,based on the summary of previous research.The scope of application of the safety model is improved and the braking strategy is optimized.The main research content of this paper is as follows:The system function requirements are determined by organizing and analyzing the latest version of China’s new car evaluation regulations.A high real-time AEB system hardware framework is designed.Relevant data processing is performed on the millimeter-wave radar and monocular camera,a multi-sensor fusion vehicle perception system is built,and a multi-sensor fusion strategy is designed.A Kalman dynamic adjustment predictive evaluation safety model based on relative speed is proposed based on the existing AEB safety model,and the AEB four-level work classification mechanism is designed,and the control strategy in the composite case is designed.A complete AEB test scene test is carried out,based on the standard test procedures and the design of the test equipment and relevant test scenarios.In summary,an automatic emergency braking system for automobiles is proposed and the working strategy of the system is studied,which enables emergency stop and slow driving when crossing pedestrians,two-wheel vehicles,longitudinal moving pedestrians,two-wheel vehicles and the vehicle in front,etc.Emergency braking in the scenario is realized.At the same time,equipment for functional testing of the automatic emergency braking system of automobiles is also developed.
