Try to use LIN communication

Communication is to send/receive information. There are, in fact, various communications formats,
such as transmission by people talking, letters written in script, and electronic communications, etc.
Among these, there are various plans for communications using electricity. This chapter explains
communications in a standard called LIN.
5.1

What is LIN?

LIN is an acronym for Local Interconnect Network, and is a type of communications protocol for
vehicle-mounted LAN. The LIN consortium was proposed in 1999 with the objective of enabling a
less expensive configuration than CAN, which is the most widespread control system
vehicle-mounted LAN. Thereafter, after several version upgrades, LIN2.0, which has added
diagnostic and other functions, was launched in 2003. Further, in 2006, the version was upgraded to
LIN2.1.
This section explains LIN applications. Concomitant with multi-function vehicles, the existence of a
network in vehicles also became indispensable. Currently, vehicle-mounted LANs are broadly
divided into two classifications: control systems, which are concerned with motoring and the vehicle
body, and information systems, which connect devices such as the satellite navigation system and
audio, and so different LANs are used depending on the application. In particular, vehicle body
devices such as electric mirrors and power windows, which are classified as body systems, do not
require such fast or detailed control. Consequently, they are also inexpensive. This is where LIN is
used.
