Have you ever wondered how many sensors are there in a car and how are they connected with each other to perform efficiently?
Yes, there are hundreds of sensors in today’s highly advanced and electronically controlled cars. Before 1983 it was a cumbersome/hectic task to install many numbers of sensors in the car because to connect each sensor there required a separate wire to connect it with the dashboard/ECU of the vehicle (point to point connection). This results in a huge bundle of wires installed in the car and that number of wires was also a challenge to handle. Also, the automobile engineers were restricted to use only a certain number of sensors in the car. So, to overcome this problem, in 1983 Robert Bosch came with a highly advanced and a very simple solution i.e., CAN PROTOCOL, but was officially released in 1986. CAN PROTOCOL is a two message, two wired based communication protocol. CAN stands for Controlled Area Network. This protocol is a set of instructions which facilitate the sensors and ECU of the vehicle to communicate with each other like ABS system, Braking system, Fuel meter, Smart A...
