Reduce the complexity of wiring harnesses and rely on the innovation of electronic and electrical architecture. According to Bosch’s electronic and electrical architecture strategy map, the electronic and electrical architecture of automobiles is mainly divided into three categories: distributed electronic and electrical architecture, domain-centralized electronic and electrical architecture, and vehicle centralized electronic and electrical architecture. Traditional cars mainly use a distributed architecture, which consists of multiple relatively independent ECUs, each ECU corresponds to its function one by one. The wiring harness is responsible for connecting different ECUs to realize the exchange of information. Therefore, under the traditional distributed architecture, the increase in the number of ECU modules and the decentralized layout will inevitably lead to an increase in the length of the wiring harness and increase the manufacturing cost. At present, the wire harness length of traditional distributed architecture vehicles is about 5km.
