Abstract

The invention discloses an electric vehicle communication electromagnetic interference suppression method based on knowledge modeling. The method comprises the specific steps: 1) carrying out knowledge modeling on an external interference source; 2) performing simulation verification on an external interference source knowledge model; 3) modeling electric vehicle communication knowledge in combination with an external interference source simulation result; 4) performing simulation verification on the electric vehicle communication knowledge model; 5) circularly judging the interference suppression effect, and ending if the requirement is met; and 6) if the requirement is not met, optimizing an interference source module, and turning to the step 3 for loop iteration until the interference suppression requirement is met. According to the invention, knowledge modeling can be rapidly and accurately carried out on a target, and electromagnetic interference suppression is realized, so that electromagnetic interference of communication equipment in operation of the electric vehicle is overcome.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle electromagnetic interference suppression, and more specifically relates to a method for suppressing electric vehicle communication electromagnetic interference based on knowledge modeling. Background technique [0002] During the transmission and control of power and signals of electric vehicles, various high-voltage and low-voltage electronic and electrical equipment on board, including drive motors, power device switches, communication equipment, power battery packs and their derived management system hardware, etc., are often powered on. or closed state. Different electromagnetic radiation will inevitably be generated by the electric spark generated by the electrical switch instantaneously, as well as the motor starting, the rapid rectification of the motor, and the high-voltage radiation. Therefore, there are many different sources of electromagnetic interference in the whole electri...
