The invention provides a method and a device for dynamically diagnosing and extracting an actual operation NOX high-discharge adverse condition of a diesel car. Through mounting an on-vehicle terminalonline monitoring system on an OBD diagnosis interface of the diesel car, an operation parameter of the diesel car is acquired in real time. The operation parameter is uploaded to a cloud monitoringplatform in real time through GPRS technology, and is stored in a database in real time, thereby realizing dynamic diagnosis and extraction to the actual operation NOX high-discharge adverse conditionof the diesel car. The invention provides the method and the device for realizing dynamic diagnosing and extracting to the actual operation NOX high-discharge adverse condition of the diesel car based on the on-vehicle online monitoring system, thereby supplying technical supports for optimized calibration on the actual operation NOX high-discharge adverse condition of the diesel car. Not only can NOX discharge of the dies
