Abstract

The invention discloses a vehicle electromagnetic compatibility simulation method, equipment and device, and a storage medium. The method comprises the following steps: carrying out the topological decomposition of an interference source and a sensitive device in a vehicle system according to a coupling path to obtain a plurality of subsystems, acquiring the port parameters of each subsystem, constructing a multi-port network model of each subsystem, integrating the multi-port network models of the subsystems according to a preset port connection relationship to obtain a global network model,carrying out vehicle electromagnetic compatibility (EMC) simulation according to the global network model, and obtaining a simulation result. Because the vehicle system is decomposed into the plurality of subsystems, and then multi-port network modeling is carried out on the subsystems, so compared with the prior art, the method of the invention guarantees that the coupling coefficients of the subsystem ports do not influence each other, the simulation time is shortened, the simulation speed is increased, and the vehicle development period is shortened as a whole.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle electromagnetic compatibility simulation method, equipment, storage medium and device. Background technique [0002] At present, with the development of the automobile industry, the requirements for automobile safety, comfort and functionality are constantly improving, and various wireless communication and radar systems and other equipment are used in automobiles, which makes the electromagnetic compatibility of automobiles very complicated. The prediction of automotive electromagnetic compatibility (EMC, Electromagnetic Compatibility) issues relies on EMC modeling and simulation. The existing automotive EMC modeling methods model the overall system of the vehicle system, but for the highly complex electromagnetic compatibility in the vehicle system The problem is that existing modeling methods are slow to simulate, which leads to extended vehicle development cycle...
