Typical applications for the LIN bus are assembly units such as doors, steering wheel, seats, climate regulation, lighting, rain sensors etc. The cost-effective nature of LIN allows for the introduction of mechatronic elements such as actuators, smart sensors, or illumination; all of which can be easily connected to the in-car network and become accessible to all types of services and diagnostics. When asking where the LIN network protocol can be used, one can easily see the possibilities are nearly endless. The first LIN enabled vehicles have already proved success since its introduction in 2001. While the LIN specification is still in its infancy, it is expected that the number of LIN nodes will grow rapidly to 20 per vehicle over the next decade; a volume of about 1.2 billion nodes worldwide each year.
