Fault Finding System for vehicle Using I2C Bus

Now a days automotive electronics is rapidly advancing in driver assistance system. Current vehicles generally use different networking protocols to integrate these driver assistance systems into vehicle, like RS 232, RS 422 and RS 485. These protocols are only used to transport the message. It is required to find the faults which occur in vehicles. Existing protocol does not meet this requirement. CAN(controller area network) is an attractive solution for it with the embedded control systems due to its low cost, light protocol management, the deterministic resolution of the contention and built-in features for error detection and retransmission. Fault confinement is a major benefit of CAN. This paper explains design and development of the CAN bus like environment using I2C bus for monitoring the vehicle's parameters like blown fuse indication, temperature and controlling.
