为了了解和掌握实际工作中的车辆发动机的技术状况 ,基于实车在线检测的车辆发动机性能参数 ,提出了以模糊数学诊断车辆发动机技术状况的方法。建立了模糊模式识别模型 ,定义了诊断参数。以 12 15 0 L型车辆发动机为例进行了技术状况的诊断 ,结果表明这种模型对于车辆发动机具有实用价值
In order to understand and master the technical status of vehicle engine in actual work, a method to diagnose the status of vehicle engine based on fuzzy mathematics is proposed based on vehicle engine performance parameters of on-line detection of real vehicle. A fuzzy pattern recognition model is established and the diagnostic parameters are defined. Taking the 12 15 0 L-type vehicle engine as an example, the technical status of the vehicle was diagnosed. The results show that this model has practical value for the vehicle engine
