Abstract The rising numbers of sensors, actuators and electronic controls increased the complexity of automotive networks. Moreover, multiple network systems have evolved to meet the different requirements coming from automotive applications. A gateway Electronic Control Unit (ECU) is a central network interconnecting system to link various field buses in a vehicle. In this paper, a gateway ECU is proposed to interconnect Controller Area Network (CAN) and Local Interconnect Network (LIN) field buses for Low Price Vehicles (LPVs). A gateway ECU is necessary for addressing the communication and network challenges in todays vehicles. A study is conducted to know about existing commercial gateway ECU, and derive the specification for a gateway ECU suitable for LPVs. The proposed gateway ECU is designed based on this specification and implemented using PIC microcontroller and line transceivers for interconnecting LIN and CAN buses. The designed gateway ECU has been successfully validated using two other nodes-one node with LIN and another with CAN networks. The proposed gateway ECU has optimal functionality and is cost effective solution for LPV segments. The trends in automotive networks and electronics show that the LPV needs to have only CAN and LIN networks in next one to two decades. In short, the proposed gateway ECU has optimal balance between functionality and cost, and is best suitable for LPVs.
