The method, system and electronic equipment for diagnostic control and fault handling of an electric supercharger according to the present invention obtain the diagnostic signal of the electric supercharger; obtain abnormal signal information according to the diagnostic signal, and perform threshold calibration on the abnormal signal information to obtain Threshold calibration information; determine the fault strategy corresponding to the abnormal signal according to the threshold calibration information, and define a fault code according to the fault strategy; classify the fault strategy according to the fault code to obtain fault classification information; For the fault classification information, the ESC is interacted with the controller to obtain the fault interaction information; according to the fault classification information and the fault interaction information, each controller is instructed to handle the fault. Compared with the prior art, the present invention integrates diagnostic signal processing, fault code formulation, fault code classification, fault information interaction, and fault handling mechanism, and realizes the OBD function of the vehicle equipped with an electric supercharger.
Description
technical field [0001] The present invention relates to the field of automobiles, in particular to a method, system and electronic equipment for diagnostic control and fault handling of an electric supercharger. Background technique [0002] The vehicle pressurization system pre-compresses or cools the air or combustible mixture entering the engine cylinder to increase the density of the air or combustible mixture entering the cylinder, thereby increasing the quality of the charge, and in the oil supply system With the proper cooperation of the engine, more fuel can be burned well, so as to achieve the purpose of improving engine power, increasing specific power, improving fuel economy, and reducing exhaust emissions and noise. In order to achieve a better supercharging effect, a two-stage supercharging system is often used, and an advanced two-stage supercharging system is a key technology to achieve higher efficiency and performance of the engine. Under the general trend ...
