Abstract

The invention discloses a brake failure diagnosis method for a freight vehicle on a long downhill road section, and belongs to the field of intelligent transportation. According to the invention, theproblem that no effective means for detecting the braking failure of a freight vehicle on a long downhill road section exists at present is solved. The method comprises the following steps of: 1, detecting driving data of vehicles by using video, radar and GPS sensors, and carrying out certain data processing; 2, defining a brake failure speed by using the section driving speeds of the vehicles, and screening and diagnosing a target vehicle; 3, detecting the behavior performance of the vehicle by using the vehicle driving data, and carrying out behavior abnormality judgment; and 4, constructing a Bayesian network, carrying out brake failure diagnosis on the vehicle with abnormal behaviors by utilizing the vehicle behavior detection results in multiple detection units, and outputting a diagnosis result. The method can be applied to brake failure diagnosis of freight vehicles on long downhill road sections.

一种长下坡路段货运车辆制动失效诊断方法，它属于智能交通领域。本发明解决了目前缺少有效的长下坡路段货运车辆制动失效的检测手段的问题。本发明方法包括如下步骤：步骤一：利用视频、雷达、GPS传感器检测车辆的行驶数据，并进行一定的数据处理；步骤二：利用车辆的断面行驶速度进行制动失效速度界定，筛选诊断目标车辆；步骤三：利用车辆行驶数据，检测车辆的行为表现，并进行行为异常判定；步骤四：构建贝叶斯网络，利用多检测单元内的车辆行为检测结果对行为异常车辆进行制动失效诊断，并输出诊断结果。本发明可以应用于长下坡路段货运车辆制动失效诊断。
