Abstract

The embodiment of the invention provides a fault recording method and device, a storage medium and computer equipment. The method comprises the following steps: sending a function addressing signal to a set domain port through a controller local area network Can box according to a set time interval; receiving a current fault signal sent by the set domain port through the Can box in response to the function addressing signal; judging whether the current fault signal is the same as the previous fault signal or not; and if the current fault signal is judged to be different from the previous fault signal, storing the previous fault signal. In the technical scheme provided by the embodiment of the invention, the current fault signal can be compared with the previous fault signal based on the Can box, and when the current fault signal is judged to be different from the previous fault signal, the previous fault signal is stored, so that invalid fault records are reduced, and the fault recording efficiency is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of vehicles, in particular to a fault recording method, device, storage medium and computer equipment. 【Background technique】 [0002] With the maturity and gradual promotion of new energy technologies, the attention and popularity of electric vehicles are getting higher and higher. Compared with traditional vehicles, the high and low voltage electronic control components of electric vehicles have increased, and the electronic and electronic control technology requirements for key technologies such as power battery management, drive motor control, and vehicle control have increased. It is necessary to test electric vehicles and record them. Fault. [0003] In the related technology, it is necessary to manually test the data and record the faults in the test, so that there are many manual steps and the efficiency of fault recording is reduced. 【Content of invention】 [0004] In view of this, the embodim...
