• As vehicles become more intelligent, in-vehicle networking (IVN) systems such as controller area network(CAN) are essential for the convenience and safety of drivers. To expand the applicability of IVN systems, attention iscurrently being focused on chassis networking systems that require increased network capacity and real-time capabilities. FlexRay was developed to replace CAN protocol in chassis networking systems, to remedy the shortage of transmissioncapacity and unsatisfactory real-time transmission delay of conventional CAN. However, FlexRay network systems require acomplex scheduling method, which is a barrier to their implementation as chassis networking systems. In particular, if we wantto migrate from a CAN network to a FlexRay network using the well-defined CAN message database, which has beenspecifically constructed for chassis networking systems by automotive vendors, a new type of scheduling method is necessaryto reduce scheduling efforts during the software development process. This paper presents a node-based scheduling methodfor easy migration from a CAN network to a FlexRay network system. To demonstrate the feasibility of the technique, itsperformance is evaluated in terms of various software complexity indices. KCI Citation Count: 1
