Do You Really Know What LIN is?
LIN stands for Local Interconnect Network. Yes, from those words, we can say that it's a local network. But do we really know how it works? A LIN consists of LIN Master and a LIN Slave. Data is exchanged and encapsulated in data frames with a fixed structure. These data frames always contain c break field that indicates a new incoming frame.
Here’s a video that explain what LIN is:
Here are the advantages of using LIN
Cheaper than CAN and other communications buses
Extension easy to implement
No protocol license fee required
Although LIN is now a full replacement to the CAN bus, it will always be a good alternative whenever low costs are essential while speed/bandwidth is not important.
Below are the applications where LIN can be used:
Roof – Sensor, light sensor, light control, sun roof
Steering Wheel – Cruise control, wiper, turning light, climate control, radio
Seat – Seat position motors, occupant sensors, control panel
Engine – Sensors, small motors
Climate – Small motors, control panel
Door – Mirror, central ECU, mirror switch, window lift, seat control switch, door lock
