Abstract

OSEK/VDX is an important specification in the field of automotive electronics and OSEK COM specifies the data communication behaviors inter-ECU and intra-ECU, but doesn´t appoint specific underlying layer. In this paper,OSEK COM is implemented based on CAN bus. We present a model that dynamically generates properly CAN identifier to schedule I-PDUs of OSEK COM and transmit data that is longer than 8 bytes on CAN. As an important part of CAN identifier, node priority is dynamically adjusted according to the actual network state by the node priority update protocol. The model has implemented on Santana Light Demo System.
