自动紧急制动系统仿真及测试平台研究
Research on simulation and testing platform for AEB system
摘要
Abstract
In order to solve the issues of lacking physical linkage in autonomous driving virtual scenario testing,as well as the long cycle and high cost of real-vehicle mileage testing,hardware modules such as multi computer system,communication,signal acquisition and wheel speed simulation are designed based on virtual scene construction technology and combined with the autonomous vehicle chassis by wire architecture,and a set of autonomous emergency braking(AEB)system simulation testing bench is built.According to the working principle of AEB system and the safety distance model based on time-to-collision,a three-level control strategy algorithm for AEB system is designed.The virtual simulation scenarios and vehicle models are constructed by means of CarSim.The AEB control algorithm was tested on the simulation testing platform for its automatic braking performance under three conditions:stationary target,moving target,and braking target.The testing results indicate that the tested AEB can control the vehicle to brake's and decelerate under all three testing conditions,effectively avoiding collisions and demonstrating good braking stability.The testing platform can successfully simulate and display the testing results for the AEB system,verifying the feasibility of the designed testing platform.It can meet the testing requirements for the AEB.关键词
