Electronic throttle valve driving circuit diagnosis method and system, and readable storage medium

Abstract

The embodiment of the invention discloses an electronic throttle valve driving circuit diagnosis method and system, and a readable storage medium. The electronic throttle valve driving circuit diagnosis method provided by the embodiment of the invention comprises the steps: reading the current state of a driving module, wherein the current state of the driving module comprises an abnormal closingstate or a normal working state of the driving module; according to the current state of the driving module, detecting the restarting frequency of the driving module or reporting that no fault exists;and according to the restarting frequency of the driving module, restarting the driving module, and adding one to the restarting frequency of the driving module or reporting fault. According to the technical scheme provided by the embodiment of the invention, unnecessary power failure caused by accidental faults of the electronic throttle valve is avoided, and the reliability of the vehicle is improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of automobile throttle, and in particular to a diagnostic method, system and readable storage medium for an electronic throttle drive circuit. Background technique [0002] The electronic throttle is a key component used to adjust the air intake of a gasoline engine, and the diagnosis of its drive circuit is of great significance to vehicle safety, reliability and maintenance convenience. [0003] Existing implementation of electronic throttle drive circuit diagnosis is to use the self-diagnostic function of the throttle drive chip to identify faults. State, and automatically shut down the throttle drive to cut off the power of the throttle, the application software reads the register status of the drive chip, and obtains the diagnosis result of the short circuit of the electronic throttle drive circuit. [0004] Due to the complex operating environment of the vehicle, there is ele...
