Design of FlexRay-CAN gateway using node mapping method for in-vehicle networking systems

As vehicles become more intelligent, in-vehicle networking (IVN) systems, such as the controller area network (CAN) and the FlexRay network, are essential for the convenience and safety of drivers. To expand the applicability of IVN systems, attention is currently being focused on the communication between heterogeneous networks such as body or chassis networking systems. The message mapping based gateway was developed to improve communication between FlexRay and CAN networks concerning vehicle information. However, there are obstacles to the wide acceptance of the FlexRay-CAN gateway for a vehicle such as ID changing or software complexity. In order to overcome these obstacles, this paper presents a FlexRay-CAN gateway using a node mapping method.
