Abstract

The invention discloses an ECU data detecting method and device. The method comprises the steps that analysis use cases are allocated in advance, the analysis use cases are function modules which are used for analyzing whether ECU data meet appointed conditions, the ECU data obtained by collecting are acquired, an appointed analysis use case is obtained, wherein the appointed analysis use case is an analysis use case selected from the analysis use cases which are allocated in advance according to detecting needs; the appointed analysis use case is used for analyzing the obtained ECU data to obtain detecting results. According to the method, manual analysis is of no need, and the purpose that detecting efficiency of ECU performance is improved can be achieved.

Description

technical field [0001] The invention relates to the field of electronically controlled diesel engine detection, in particular to an ECU data detection method and device. Background technique [0002] The electronic control unit (ECU, Electronic Control Unit) of the electronically controlled diesel engine receives signals from various sensors, and with the help of the solenoid valve on the injector, allows the diesel to inject the correct injection at the correct injection point with the correct injection pressure. Oil quantity ensures good economy and minimum pollution emission of diesel engine. [0003] In order to ensure the performance of ECU software and hardware systems, it is necessary to collect a large amount of ECU data for a period of time and feed it back to developers during the small-batch trial investment stage of ECU development. Developers will manually analyze the ECU data collected at various time points during the collection period to detect the software ...
