Design And Development Of Adaptive Cruise Control Systems Hardware In The Loop Test Platform

With the coming of intelligent era,the concept of driverless is more and more popular.The Advanced Driver Assistance Systems(ADAS)is considered to be the only way to driverless.As an important part of many functions of ADAS,the adaptive cruise control system(ACC)has attracted more and more attention.In order to ensure the safety and reliability of ACC system,how to test and evaluate ACC system efficiently is very important.Aiming at the above problems,this paper develops the hardware in the loop test platform of ACC system,which can realize the comprehensive test of ACC system,greatly improve the development and test efficiency of ACC system,and reduce the development and test cost.At the beginning of the article,the research background and significance of this paper are described,and the research content of this paper is put forward on the basis of the above discussion.After analyzing the working principle of ACC system,combined with the principle of hardware in the loop test technology,the overall architecture of ACC system hardware in the loop test platform is designed.The hardware architecture of ACC hardware in the loop test is proposed,including hardware selection,interface configuration,parameter adjustment of test modules,and the design and development of corresponding necessary modules,which are finally integrated into a complete test system.Then,the software architecture of the test platform is designed,including the driver model,vehicle dynamics model,vehicle power system and brake system control model and bus conditioning model.Finally,by analyzing the international laws and regulations,the corresponding test scenarios are designed to meet the requirements of ACC system,and the simulation test of ACC controller samples is carried out.The test results verify the effectiveness and practicability of the platform.The advantages and disadvantages of the test are summarized,and the future work is prospected.
