In Car Communication Network Protocols

There has been a significant growth, starting from the year 1998, in the amount of electronics available in cars. Now every function ranging from temperature control to navigation systems is controlled electronically by an ECU (Electric Control Unit).
This is a trend that is expected to continue as vehicles manufacturers attempt to make further advancements in safety, mileage, comfort and reliability.
As the number of ECUs used in cars is getting increased, the need for an efficient and reliable networking system rises. The hike in the use of such in-vehicle network technologies is expected to boost revenues of the measurement and communication industry.
Automotive manufacturers and suppliers have been working together with the common goal of standardizing in-vehicle network protocols.
The growing demand for safety, comfort, reliability and infotainment requires incorporation of multiple protocols. This trend is expected to continue as automotive manufacturers introduce a large number of electronic devices to enhance the value of their product and to cater to changing industry requirements.
