Design of CAN Bus for Research Applications Purpose Hybrid Electric Vehicle Using ARM Microcontroller

AbstractResearch Centre for Electrical Power and Mechatronics, Indonesian Institute of Sciences has built test vehicle which able to monitored several parameters. The monitored data were communicated with serial protocols (RS232 and RS485) both protocols need master control like computer or microcontroller. There are several disadvantages using centralize control which are dependencies to master control and complicate wiring. To solve this problem need to design bus protocol, which able to multi master protocol. CAN is a multicast-based communication protocol (multi master) characterized by the deterministic resolution of the contention, low cost and simple implementation. This paper will purpose CAN bus multi master design protocol for research applications purpose hybrid electric vehicle using Nuvoton™ arm microcontroller
