CAN bus technologies - Essay ExampleThis caused many problems in the after(prenominal) sales repairs as each of the models had a different set of wiring, which meant qualified and trained staff to work out the repairs or even the general maintenance. The intermingling of the wires was as well causing problems. Hence, a privation was felt to have the vehicle control system that will eliminate largely the number of connectors and the resultant wiring problem. This need gave birth to the invention of CAN bus technology.Mr. Robert Bosch introduced the CAN bus system for the first time at a SAE congress in 1986 at Detroit. This resulted in the vehicle wiring getting reduced up to 2Kms. Thus, the overall weight of the vehicle was reduced up to 50 Kgs. In a vehicle a care(p) BMW 850 coupeController Area Network serial bus system, called as CAN bus technology is designed to support multi master access, while handling unmindful messages up to 8 bytes. While this means that collusions get resolved by priority, the system offers high degree of reliability also, by having 15 bit CRC for both message.Since itd introduction at Society of Automotive Engineers (SAE), there have been many further innovations in the CAN technology. While Intel developed CAN chip 82526 and Philips also developed semiconductor 82C200 as a CAN controller, there are about 20 chip manufacturers catering to this technology now. CAN technology organism purely a data link layer implementation program, it became quite popular for use in various capital equipment like textile machinery, away from its original use in passenger cars and other transport vehicles. However, this further gave rise to the need of having standards for these layer implementations and data exchange programs.Apart from the above, standardization like EN50325 have enabled application layers now to be used in different kinds of machine controls with the use of components like DeviceNet and CANopen. Both these are addressing di fferent applications. While CANopen is effective for almost
