| The rapid development of science and technology has driven the continuous growth of the national economy,and the number of car ownership has also increased year by year.While bringing convenience to people,traffic accidents have become increasingly frequent,causing serious casualties and huge economic losses.Therefore,the research on the safety of automobiles has become a key technology to be solved urgently.In many traffic accidents,automobile collision accidents account for a large proportion,and related research has been carried out at home and abroad.However,there are still many unsolved problems in this technology field so far.research on intelligent anti-collision control technology can effectively avoid or reduce the occurrence of such accidents,has high practical value and important social significance.In this paper,intelligent anti-collision control system is designed for the collision of the driving car.The control system uses the radar sensor test device to automatically identify the vehicles,pedestrians or other obstacles that may collide with the vehicle on the road.After that,the safety car distance model is studied and analyzed.When the vehicle and the front obstacle are close to a certain distance range,the control system will automatically issue an alarm to remind the driver to perform the deceleration operation.If the driver does not take any measures,it will reach a certain distance.will automatically take braking measures to prevent collisions with other vehicles or obstacles.Finally,hardware and software were designed and corresponding experimental scheme was designed according to the system function and tested.Experimental results show that the anti-collision intelligent control system can meet the expected requirements,effectively avoid the occurrence of a collision accident.Simulink software was used to model and simulate the car anti-collision intelligent system again to further verify the feasibility.From the speed and time,distance and time response diagrams,we can see that system has a good effect on the control of the vehicle speed and safety distance,making the car more intelligent and humanized,and ultimately achieving the purpose of safe driving.The research of this topic can help the driver to reduce the collision accident to the greatest degree,and maximize the active safety of the car,which is helpful to the promotion and application of car anti-collision intelligent technology. |
