AI Technical Summary

Technical Problem

Existing detection systems cannot effectively simulate the electromagnetic coupling effects between the vehicle's electrical domains, especially the impact on other electrical domains of the vehicle when powered by high voltage, making it difficult to perform realistic simulations without using a complete vehicle or major components.

Method used

A detection system comprising a voltage source, a simulator module, and a conductive body replacement device is employed. The simulator module simulates the electrical characteristics of electrical components, and the conductive body replacement device simulates the electromagnetic characteristics of the vehicle body. Combined with a model-based control device and domain control signals, accurate simulation of the vehicle's electrical domain is achieved.

Benefits of technology

It can more realistically simulate the electromagnetic coupling effect between different electrical domains of a vehicle, simplifying the detection process, improving the accuracy and reliability of the detection system, and reducing dependence on actual vehicles.
