基于毫米波雷达的自动紧急刹车系统设计

Design of Autonomous Emergency Braking System Based on Millimeter Wave Radar

设计了一种基于毫米波雷达的自动紧急制动(AEB)控制系统,其能够自动检测前方的障碍,并在紧急情况下发出预警信号提醒驾驶员制动甚至主动强制制动,保证驾驶员安全。基于ARS408-21毫米波雷达,设计了上位机雷达标定软件用于配置、标定雷达参数和获取雷达检测的目标信息。基于MPC5748G微控制器设计了外围电路系统板,作为AEB系统主控制器。制定了基于车速和碰撞时间的预警和紧急制动策略。AEB系统的实车试验结果表明,系统功能符合设计要求,提升了汽车的主动安全性能。

An automatic emergency braking(AEB)control system based on millimeter wave radar is designed,which can automatically detect obstacles in front and remind the driver to brake or even actively brake in an emergency to ensure the safety of drivers.Based on the ARS408-21 millimeter wave radar,the upper computer radar calibration software is designed to configure,calibrate the radar parameters and obtain the target information of the radar detection.Based on the MPC5748G microcontroller,the peripheral circuit board is designed as the main controller of the AEB system.Early warning and emergency braking strategies based on vehicle speed and collision time were developed.The vehicle test results of the AEB system show that the system function meets the design requirements and improves the active safety performance of the vehicle.
