使用快速多参数诊断设备,已经成为当代的趋势。诊断已经不单是查找故障的手段,而且为改变保养修理制度的性质,引用控制理论对车辆技术状况实行控制创造了条件。目前,不仅保养修理部门采用诊断,制造厂也应用。为了使诊断达到更加显著的技术经济效果,研究有关诊断的基础理论,例如状态参数划分、结构参数和诊断参数的选用、故障形成和车辆技术状况控制机理、诊断设备设计原则和应用诊断的技术经济效果等,势必成为迫在眉睫的课题。
The use of fast multi-parameter diagnostic equipment has become a contemporary trend. Diagnosis is not only a means to find fault, but also to change the nature of maintenance and repair system, citing control theory to control the technical conditions of vehicles to create the conditions. At present, not only the diagnosis and repair department maintenance, manufacturing plants are also applied. In order to achieve more significant technical and economic results of diagnosis, the basic theory of diagnosis, such as the classification of state parameters, the selection of structural parameters and diagnostic parameters, the formation of faults and the control mechanism of vehicle technical conditions, the principle of diagnostic equipment design and the technical economy of applied diagnosis Effects, etc., is bound to become an urgent issue.
