Interior Cabin Communication Bus

CAN is a fast differential bus used as a backbone for high-speed communication between many CAN and LIN nodes. Due to its slower speed, LIN is a sub-bus that leverages CAN’s robust architecture and speed. Shown here, CAN is the communication backbone and LIN are distributed sub nodes. The CAN ECU sends out commands over the fast CAN bus to specific LIN nodes responsible for functional, and comfort applications, applications that do not require a fast response. For example, functional applications can include steering wheel, instrument cluster, and door functions. Other ECU commands can be for comfort related applications such as climate control, seat adjustments, and ambient lighting. For this PTM we will focus on LIN RGB ambient lighting.
