As vehicles become more intelligent, in-vehicle networking (IVN) systems such as controller area network (CAN) or FlexRay 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 networking systems or chassis networking systems. Message mapping based gateway was developed to communicate between FlexRay and CAN network to improve exchanging information of vehicle. However, there are obstacles for the wide acceptance of the FlexRay-CAN gateway of vehicle. First, when message ID was changed of network, gateway must be reloaded changed message mapping table. Second, if the exchanging message is increased in the network, software complexity of gateway is increased rapidly. In order to overcome these obstacles, this paper presents a node mapping -based FlexRay-CAN gateway for IVN systems. In addition, this paper presents a node mapping based FlexRay-CAN gateway operation algorithm along with the experimental evaluation for ID change.
