The invention relates to the technical field of vehicle test, in particular to a commercial vehicle forward collision early warning test evaluation system and method. The system comprises a fixed base station located beside a test lane, and a positioning module, an acquisition module, a processing module and an analysis evaluation module which are located on a test vehicle. The method comprises the following steps: enabling a test vehicle to be located behind a target vehicle, driving in the same direction on a test lane according to a preset condition, carrying out field test under various test conditions, and starting the field test when the preset parameters of the test vehicle reach preset values; acquiring the identification information of the target vehicle by a forward collision alarm system, and finishing the test when the test vehicle meets the ending condition; and determining a preset range of scoring according to the test conditions, judging position information of the identification information in the preset range, and carrying out test scoring on the forward collision alarm system of the test vehicle according to the position information. According to the invention, the sensitivity and accuracy of the alarm prompting function of the forward collision alarm system are ensured.
本发明涉及车辆测试技术领域,具体涉及商用车前向碰撞预警的测试评价系统及方法,系统包括位于测试车道旁的固定基站,包括位于测试车辆上的定位模块、采集模块、处理模块和分析评价模块;方法包括让测试车辆位于目标车辆的后方,在测试车道上按照预设条件进行同向行驶,并以多种测试条件进行实地测试,在测试车辆的预设参数达到预设数值时,启动实地测试;对前向碰撞报警系统对目标车辆的识别信息进行获取,当测试车辆满足结束条件时完成测试;根据测试条件确定评分的预设范围,并判断识别信息在预设范围内的位置信息,根据位置信息对测试车辆的前向碰撞报警系统进行测试评分。本发明保证前向碰撞报警系统进行报警提示功能的灵敏度和准确性。
