PROCESSING OF INFORMATION GATHERED FROM HYBRID OR ELECTRICAL VEHICLE FOR REDUCTION OF FUEL CONSUMPTION AND GAS EMISSION

摘要

A hybrid electric vehicle (HEV) combines a conventional internal combustion engine (ICE) propulsion system with an electric propulsion system. A variety of types of HEV exist, the most common form of HEV is the hybrid electric car. The congestion phenomena in urban areas provokes an over consumption of fuel and an over emission of harmful gases. The information about congestion, the vehicle state and the recharging points can be of great interest in vehicle and energy management. In this purpose, it needs a lot of information about vehicle state, like the level of battery charge, the motor state, the level of fuel tank and so on. Hence, the potentials of in-vehicle systems are currently investigated to improve this situation. In this paper, an embedded system which can collect a lot of important context information is designed and realized by authors, a Controller Area Network (CAN) is realized for connecting sensors to collect information. Thanks to a diagnostic interface, this system is also plugged into the vehicle existing CAN bus and some CAN bus messages have been decoded by our Labview program. All gathered information are shown on a touch screen. Wireless communication technologies ZigBee and GPS/GPRS allow communicating with other vehicles or an infrastructure.
