THE CAN BUS

摘要

As the use of computers (control modules) became more common to a variety of vehicle systems,rnit became obvious that some means of allowing these computers to share information was needed to avoid redundant wiring. Imagine having tornhard wire each sensor to every computer that may need its input and the complexity of the wiring harness that would result.rnEnter the bus - a single or dual wire system that allows these computers to be interconnected, with information shared along this system that all could use. In its most basic interpretation, a bus is nothing more than a phone line allowing each computer connected to it to call another, asking for the shared information needed to carry out its programming.
