New Concept for Reducing Wire-Harness and Implementing Advanced Facilities for Non-Luxury Vehicles via Application of POF

In the past decade automotive industries being faced the exponential increase of in-vehicle electronic devices. The hydraulic systems are replaced with sophisticated electronic systems. Market demands for exploiting new in-vehicle technologies such as multimedia systems, internet access, GPS, Mobile communication, internal private network; engine, body and power train intelligent control and monitoring systems are increasing daily. These new needs make the wire-harness as physical pathway for power and data more complex. The amount of different data types transmission in vehicle networking requires higher bandwidth and subsequently applying expensive and advanced equipment. Furthermore functions and facilities lead to raise the number of electronic control units (ECU). The high cost of manufacturing and implementing the previous equipment and systems only can be justified to luxury vehicles high prices. This paper presents a conceptual model of in-vehicle networking which would lead to the appliance of considerable portion of these advanced systems in non-luxury vehicles. In this context, polymer optical fibers (POF) exploited to achieve high speed bandwidth and cost-effective solution to transfer huge amount of data and one ECU to control and manage body/cabin electronic devices. This paper suggests three red, blue and green lights for transferring video/audio, communication data network such as internet/vehicle internal network and body/cabin command lines respectively. Moreover, this concept model claims for reducing wire-harness with integration of command lines into multiplexed POF line.
