Fault finding system in vehicle using I2C bus

Abstract

Automotive electronics is rapidly expanding area with an increasing number of safeties, driver assistance and infotainment devices becoming standard in new vehicles. Current vehicles generally employ number of different networking protocols like RS485, RS232, and RS422 to integrate these systems into the vehicles. The introduction of large numbers of sensors like water level sensor ,coolant temperature sensor, pressure sensor to provide driver assistance applications and the associated high-bandwidth requirements of
these sensors have accelerated the demand for faster and more flexible network communication technologies within the vehicle. In this project, we design and develop CAN bus like protocol using I2C bus which is control by PC. In this we connect PC through USB port to vehicles dashboard to monitoring the parameters like blown fuse indication, temperature, oil level and controlling .Characteristics including less circuit complexity and faster speed of data transmission
