摘要
设计了一种基于毫米波雷达的盲区信息系统(BSIS),该系统能够自动检测商用车右侧盲区的骑行者,对驾驶员进行信息信号提示,并在紧急情况下发出碰撞警告信号,提醒驾驶员制动,保证盲区内的骑行者安全.基于TIAWR2944 的毫米波雷达,设计了一套集信号检测、信号处理、目标分析和预警策略的软件.利用AWR2944SOC芯片的处理能力,制定并实现了根据本车与目标间的相对距离来判断碰撞发生可能性的系统策略.BSIS系统的实车试验结果表明,系统功能符合设计要求,提升了商用车的主动安全性能.
Abstract
A blind spot information system(BSIS)based on millimeter wave radar is designed,which can automatically detect vulnerable road users in the blind spot on the right side of commercial vehicles,provide information signal prompts to the driver,and issue collision warning signals in emergency situations to remind the driver to brake and ensure the safety of riders in the blind spot.based on TI AWR2944 millimeter wave radar,the software is designed for signal detection,signal processing,target analysis,and early warning strategies.Through the processing capability of the AWR2944 SOC chip,the system strategy is developed and implemented to determine the possibility of collision based on the relative distance between the vehicle and the target.The actual vehicle test results indicate that the system functions meet the design requirements and improve the active safety performance of commercial vehicles.
