汽车电脑诊断的现状和未来

Present and Future Development in Vehicle On-Board Diagnostics

汽车电脑诊断的首要目的是快速准确地发现汽车控制部件的故障，其次是控制汽车排气．安全驾驶以及汽车生产线组装的质量检查。随着全球性的环保要求日益高涨，汽车废气的转换除污处理更依赖电脑。同时，汽车安全舒适性的提高，也要由汽车电脑的动态回馈，实时地显示在汽车仪表盘上。就目前的汽车电脑诊断技术作一初步的系统介绍，并将其未来发展也作一个展望。

The Primary purpose of vehicle On-Board Diagnostics (OBD) is to identify faults in the control system in vehicle. This infortnation can be also used for exhaust control,safety and assembly quality improvement. With the tightening of the requirement for global environment,more and more computers are used in vehicle exhaust control. In addition, dynamic response of the vehicle conditions through the use of computer diagnostics can be used to improve the comfortibility. This paper presents a brief review of current status computer-based OBD system,as well as its future trend.
