随着社会进步和科技发展,对轿车的主体要求,从之前最基本的能满足代步需求,到现在苛求舒适性,追求操控性,要求安全性等更多的标准,要达到这些标准则离不开现代电子设备的广泛应用。据粗略统计,一般中级轿车上,其控制单元数量少则20个左右,多则30~40个,甚至更多。这么多控制单元的正常工作还离不开各种各样的传感器,当然还包括线路的连接。因此现在轿车相比之前的轿车,其零部件的数量成倍地增加,这也是现在单车的故障率相比老款车型更多的一个原因。而电子元件的故障现象,不像机械故障那么直截了当出现,很多时候可能表现出时好时坏的特征,姑且称之为软性故障。软性故障往往是客户抱怨最多的,维修技师最难彻底解决的。基于此大众开发了远程诊断设备,本文通过远程诊断设备在实际维修中的应用实例,浅谈该设备对软性故障维修的实用意义。 With the social progress and technological development, the main requirements of the car, from the most basic before to meet the needs of mobility, and now demanding comfort, the pursuit of control, security and more standards to achieve these standards are not Open a wide range of modern electronic devices. According to rough statistics, the average mid-size sedan, the number of control units as little as about 20, as many as 30 to 40, or even more. The normal operation of so many control units is also inseparable from a wide range of sensors, of course, including the line connection. So now the sedan compared to the previous sedan, the number of its components increased exponentially, which is now the failure rate of a bicycle compared to older models more of a reason. The electronic components of the fault phenomenon, unlike the mechanical failure so straightforward, many times may show the characteristics of good times and bad, let’s call it a soft fault. Soft faults are often the most complained customers, repair technicians most difficult to solve completely. Based on this, the public has developed a remote diagnosis device. In this paper, through the practical application of remote diagnosis device in practical maintenance, this paper discusses the practical significance of this device in the maintenance of soft failure.
