Abstract


Serious traffic safety problems makes it increasingly high demand for car security , car security system can only play a role independent from both active and passive safety . Active and passive integrated automotive safety control system of the main passive safety combined with comprehensive security protection , the implementation of the whole process of the accident , can reduce the rate of road accidents and injury rate . In China, the research in this area has just started to study the system technical issues involved , and has an important significance for improving road traffic security . Thesis research on automobile safety control system developments and trends at home and abroad are summarized , and from the point of view of active and passive safety integration , on the basis of the definition of system functionality , the overall structure of the program and control systems for the automotive safety systems planning to determine the key technologies required to achieve the system functions and their relationship . Established according to the requirements of the total program planning , CarSim software vehicle dynamics system model to reflect the collision avoidance system dynamics , and on this basis in established the vertical inverse dynamics model , the model can simulate complex vehicle operation process , and both the accuracy and the simplicity of the model , and laid the foundation for the implementation and evaluation of automotive safety control system functions . Establish the security status of the driver operating characteristics to judge distance model , the paper on automobile collision avoidance control system design and expect to the acceleration driver preview strike , driver model of the longitudinal velocity control PID speed control , To achieve the desired speed and safe distance control . Typical conditions simulation , collision avoidance control system functions and related research content correctness verified . The results showed that : a good control system to achieve a total program planning collision avoidance reasonable automobile safety control system for program planning , can provide a valuable reference for related research and guiding role .
