摘要
现代汽车车载自诊断(OBD)系统存在一个OBD不能监测出故障(误诊)的区域,该区域定义为自诊断系统的“盲区”。产生自诊断盲区时,汽车使用性能开始下降。汽车OBD系统产生的盲区主要受电子连接及布线技术、汽车传感器质量和执行器性能、汽车接地技术等因素的影响。
The onboard diagnosis systems of modern motor vehicles have areas in which they cannot diagnose system faults.The area is defined as'blind area'of the diagnosis system.When blind area occurs,use performance of the vehicle decreases.The blind area of automotive OBD systems is mainly influenced by the electronic connecting and wiring technology,quality of sensors,performance of actuators and grounding practice.
