The LIN Bus in Modern Automotive Headlamp Systems

Modern automotive headlamp systems will rely heavily on the use of sensors and actuators in the near future. These remote sensors and actuators are connected to an electronic control unit via a bus network, and various types of bus networks are feasible.

This paper concentrates on the cost and performance advantages when using the Local Interconnect Network (LIN) bus network in a headlamp application. Various solutions are presented that provide insight into the different LIN bus architectures available. The integration of a stepper motor driver with LIN interface is demonstrated as an example. Overall, the paper shows how the LIN bus provides superior performance when combined with the appropriate system architecture for cost-sensitive applications.
