Research on Electrical/Electronic Architecture for Connected vehicles

摘要

A vast increase in automotive Electrical/Electronic systems, coupled with related demands on connection, has created an array of new engineering challenges. Strong coupling and correlative relationship between electric/electronic devices are more and more complicated, and the malfunctions and failures are more difficult even no access to detect and locate, which seriously threatens the vehicle safety. In addition, motorists' insatiable demand for comfort and convenience features is posing challenges to manufacturers in terms designing reliable vehicle's Electrical/Electronic Architecture. Based on the concept of "body and brain", a brand new Electrical/Electronic Architecture is introduced, which is a three-layered architecture. Sense & execution layer is composed of intelligent network nodes, which obtain both invehicle electric/electronic devices' states and the data from V2X, achieve real-time online diagnosis, and implement the control command to them; Network & Transmission Layer for information transmission between sense & execution layer and Decision Layer; in Decision Layer, central coordination management mechanism is set to analyse all the correlative relationship between the whole vehicle's devices, achieving coordinated control and all-around supervisory of the whole vehicle. This proposed Electrical/Electronic Architecture is demonstrated on a luxury vehicle model that in volume production, and experiments on test bench and sample vehicle are carried out to verify this structure.
