Abstract

The embodiment of the invention provides an engine detection method, an engine detection device and an engine detection system. The engine detection method comprises the following steps: arranging theengine detection device out of an engine controller to acquire to-be-analyzed performance parameters from the engine controller, wherein the to-be-analyzed performance parameters are performance parameters of an engine connected to the engine controller; and determining whether the engine is abnormal or not according to the to-be-analyzed performance parameters and pre-stored standard performanceparameters of the engine, and if so, generating alarm information. The engine detection device can take the pre-stored standard performance parameters of the engine as an analyzing standard of the to-be-analyzed performance parameters, so that the to-be-analyzed performance parameters can be analyzed quickly and accurately to know whether the engine is abnormal or not, and therefore, the engine is monitored efficiently and accurately.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to an engine detection method, device and system. Background technique [0002] The engine is the power device of the car, and its operation is the key factor to determine the performance of the car. Therefore, it is very necessary to detect and maintain the performance of the engine. At present, the country has increasingly strict requirements on the attenuation control of engine emissions throughout the life cycle. Therefore, real-time monitoring of engine performance is particularly important. [0003] At present, the engine can be detected by the engine controller. However, the storage capacity and computing power of the engine controller are limited, and the analysis of the detected performance parameters has certain limitations, which cannot accurately reflect the performance of the engine. Contents of the invention [0004] In order to solve the above technical problems, the embodi...
