At its most simple, communication is getting information from one place to another. As we saw in the article ‘why use a communication bus’ we look at a bus to simplify the control of devices with fewer wires. Ultimately we will send instructions from one device (headlight switch) to another headlight, in a digital form. Let’s see how CANBus communication might help transfer messages.<\/p>\n\n\n\n

CANBus<\/h2>\n\n\n\n

CANBus is currently the most broadly used vehicle communication method in automotive applications. To simplify the concept, we can break the compound word down to try to determine its purpose.<\/p>\n\n\n\n

The CAN element of the word stands for “Controller Area Network” and refers to a method of sending information from one device to another anywhere within the vehicle. <\/p>\n\n\n\n

The \u2018bus\u2019 is the physical media (twisted copper wires) to which all electronic devices are connected. There is often more than one single set of wires (multibus).<\/p>\n\n\n\n

CANbus is one of a number of communication buses used on modern vehicles. Other examples include LINBus, FlexRay and Ethernet. While the busses can be physically different (one, two or more wires), the primary differences in the communication types relate to the amount of volume of messages and the cost of electrical hardware.<\/p>\n\n\n\n
