Incorporation of Various Advanced In-car Applications Triggers Development of Innovative Network Technologies and Protocols

Automakers in North America are increasingly differentiating their vehicles by providing sophisticated and inventive features such as safety, stability, control, comfort, convenience, and infotainment. However, the incorporation of these applications requires a range of advanced and reliable network technologies and protocols that enable the efficient and effective networking of distributed electronic systems in a vehicle. This is aiding the development, standardization, and introduction of several application-specific network protocols such as controller area network (CAN), local interconnect network (LIN), media oriented systems transport (MOST), and FlexRay.

This Frost & Sullivan strategic analysis service provides a comprehensive state-of-the-art and analysis of the emerging in-car network technologies and protocols that hold the potential of supporting a multitude of advanced and innovative applications in the next generation of light vehicles in North America. The study covers network protocols including CAN, LIN, MOST, FlexRay, and other key in-vehicle network technologies and protocols. It also provides a comprehensive discussion of market drivers and restraints. The research service enables companies to align their positioning strategies to benefit from the changing market conditions and obtain maximum return on investment.

Application-specific Network Technologies and Protocols Required to Support New Features

Automakers are rapidly adopting generalized protocols, such as CAN, which are experiencing high implementation rates in the light vehicles market. However, to support the several new and advanced control, telematics, and infotainment applications that are fast emerging in the automotive market, there is a rising demand for application-specific networks including FlexRay, MOST, and LIN that are developed for supporting a select set of applications. In the next generation of automobiles, multiple network technologies and protocols are expected to co-exist, supporting several advanced and futuristic features and applications.

"With the convergence of electronics with automotive technologies, the average number of electronic control units in typical North American light vehicles ranges from 30 in low-end vehicles to almost 70 in high-end luxury vehicles," says the analyst of this study. "The increasing electronic content in light vehicles is expected to strongly drive the market for in-vehicle network protocols from 2006 to 2012."

Declining Implementation Costs of Protocol Nodes in High-volume Vehicles Accelerate their Adoption

The early introduction and the quasi-standardization phase of most emerging in-car network technologies and protocols are the cause for the high per node and implementation costs associated with these protocols. This is limiting their rapid adoption in the high-end vehicle segment and restraining their market penetration in volume driving vehicle segments.

"As buyers of volume vehicles are increasingly demanding greater convergence of electronics with automobiles to support innovative infotainment, safety, comfort and convenience, and control applications, these protocols are expected to be steadily introduced in high-volume vehicles, helping to achieve economies of scale," notes the analyst. "This will consequently lower prices and thereby, catalyze wider adoption in future."

   Market Sectors
 

Expert Frost & Sullivan analysts thoroughly examine the following market sectors in this research:

  • Local interconnect network technology and protocol
  • Media oriented systems transport technology and protocol
  • FlexRay technology and protocol
  • Other key in-vehicle network technologies and protocols
   Technologies
 

The following technologies are covered in this research:

  • Controller Area Network (CAN): CAN is a network protocol based on asynchronous, multi-master architecture and enables fast serial data exchange between electronic control modules in cars. CAN was developed for automotive applications that required data rates of up to one megabit per second. The CAN protocol became a universally accepted standard in 1993 and since then, the CAN-B and CAN-C protocols have been incorporated by almost all vehicle manufacturers in North America. Being a serial bus system for networking intelligent devices as well as sensors and actuators, it is the most widely used network protocol in light vehicles.
  • Local Interconnect Network (LIN): LIN is a low-cost serial communication system that can be used to connect the distributed electronic systems in a car and is being viewed as an accompaniment to the existing group of automotive multiplexing networks. The LIN bus can be used as an in-vehicle networking serial bus between intelligent sensors and actuators that operate at 12 volts. LIN supports low-cost communication for smart sensors and actuators in applications where the bandwidth and robustness of the CAN network are not required.
  • Media Oriented System Transport (MOST): MOST is a multimedia fiber-optic point-to-point network that is implemented in a ring, star, or daisy chain topology over plastic optical fibers. MOST is a versatile, high-performance, low-cost, and multimedia-specific network technology that is based on synchronous data communication. It is a serial communication system for transmission of audio, video, speech, and data signals based on optical buses.
  • FlexRay: Flex-Ray is a relatively new scalable, high-speed serial communication bus system developed for in-vehicle networks using point-to-point links. FlexRay features a deterministic fault-tolerant network system that offers error tolerance and time determinism performance at high speeds for automotive control (x-by-wire) and safety-relevant applications. It has been designed to complement CAN, LIN, and MOST networks.
  • J1939: J1939 is a protocol based on the CAN network and was developed for real-time data exchange between control devices in commercial vehicles. The J1939 protocol describes the information that is exchanged between the control units in a commercial vehicle. The Society of Automotive Engineers (SAE) published it in 1998 to support A, B, and C communication functions. Essentially, J1939 is a Class C-type communication network that supports real-time control-loop functions between distributed electronic control devices.
  • Time-triggered Communication on CAN (TTCAN): The TTCAN protocol is built on the CAN data link and is an extension of the CAN protocol, which is in the process of being standardized. The TTCAN protocol is developed in software in a higher layer over the CAN protocol and thus allows the network messages to be transmitted in both event-triggered and time-triggered mechanisms.
  • Time Triggered Protocol (TTP): TTP was developed to cater to the demand of fault-tolerant network protocol supporting safety-critical, high-speed applications. TTP offers a high degree of protocol efficiency and low implementation costs.
  • IDB 1394: The IDB 1394 is an intelligent data bus that is the automotive grade version of Firewire developed for supporting high-speed multimedia applications needing a high volume of audio/visual information to be transferred within an automotive environment. The IDB is primarily used as a consumer device bus operating over an unshielded twisted pair multi drop cable.
  • Universal Serial Bus (USB): The UBS is an external bus standard that supports data speeds of up to 12 Mbits per second and is considered the most popular bus for supporting plug and play device connectivity in the consumer electronics market. It is the most dominant bus standard for portable device connection and its huge popularity in the consumer electronics market is resulting in the automotive electronics suppliers and automakers actively considering the incorporation of USB ports in light vehicle infotainment systems.
  • Domestic Digital Bus (D2B) SMARTwireX: D2B is an optical data bus system that was developed to connect audio, video, computer, and telephone components in a single ring structure within a vehicle. SMARTwireX defines a physical layer supporting the D2B networks running up to 25 Mb/sec and featuring automotive compatibility. It is an electrical physical solution for automotive networks.
