Hybrid vehicles are becoming very popular in the market. With increase in demand for performance and efficiency in the market, new technologies are evolving. Use of electronics in automobile control systems, have become very popular. Hybrid vehicles have a very complex control system. The use of fuzzy logic in making such controllers for hybrid electric vehicles is the motive of this thesis. Similarly reducing the number of mechanically driven parts in the automobile has proven to be very helpful in improving the performance, ride quality, and also conservation of energy. Electrification of chassis to eliminate differential mechanism has been done. Further focus is given to enhance safety system in automobiles, aircrafts, battle tanks, and ships. Use of fuzzy logic to create in built fire extinguishers is yet another work in this thesis. Finally a chip is designed to create the automatic in built fire extinguishers in these vehicles.
