In the process of designing the electrical and electronic architecture, a key task is to decompose the electrical/electronic requirements based on the requirements of the whole vehicle. Vehicle requirements include mechanical, electrical/electronic, software, thermal, etc. Engineers need to extract electrical/electronic requirements from them, decompose them and coordinate the development and design of various downstream departments. Throughout the process, the various engineers involved in the definition, design, and delivery of electrical and electronic architectures must balance interdependent requirements.
