CAN currently is the de-facto standard protocol among in-vehicle networking.<br />
Not just in the basic trunk network, it is widely used in the powertrain and body<br />
systems, too.<br />

FlexRay is a high-speed communication<br />
protocol featuring<br />
superior flexibility and high reliability.<br />
Devised by automobile and<br />
electrical equipment manufacturers<br />
and semiconductor vendors,<br />
it is watched as a most<br />
promising in-vehicle networking<br />
protocol <strong>for</strong> the next generation<br />

LIN is a single-master in-vehicle networking protocol that excels<br />
in cost/per<strong>for</strong>mance ratio.<br />
It is used in switch input and sensor input actuator control.<br />
Door control Light control Door mirror control etc.<br />
The door is unlocked when a person<br />
who has a card key approaches the<br />
car.<br />

ASRB is a protocol designed <strong>for</strong><br />
the inclusion of ignition systems,<br />
such as collision sensors<br />
system.<br />
It is watched with interest as an<br />
in-vehicle networking protocol<br />
<strong>for</strong> the next generation air bag<br />
system.<br />
