LIN Bus Based Touchpad System for Smart Vehicle Cabin

Abstract

The concept of smart cabin is to offer better safety, comfort and ride the experience for vehicle drivers. In order to make this concept realize better, an array of advanced human interface (HMI) is always needed. In general, the HMI will transmit control signal either through the CAN bus, LIN bus or both to control end devices or instrumentation. This paper presents a LIN bus touchpad system (LBTS), which enables safe and efficient devices (headlight, taillight and cooling fan) access as well as control of their operating parameters.In this LBTS, the touch pad signal processing system is designed with a LIN bus based controller CS8975 developed by the company ISSI we collaborated. A high performance STM32 Nucleo-64 board is used to realize the LIN master node, dealing with the control of the LIN message sequence. With this proposed LBTS, the interior design for the smart human-centric cabin can be more flexible and innovative.
