Electrification of Chassis using Motor Assisted Differential and Reverse Motion System

There has been increasing interest for manufacturers to produce hybrid vehicles. This is due to high pollution levels, increasing fuel prices, and customer demands of fuel efficient vehicles. Similarly there is interest in use of electrical components instead of mechanically operated ones in automobiles. Mechanical differential is used in automobiles for providing torque transmission through 90 degrees from the engine drive shaft to the road wheels. The objective of this paper is to propose the use of electric motors instead of the differential mechanism. The motors are controlled by fuzzy logic rules, and help in electric current generation when the vehicle travels on highways. The objective of elimination of the mechanical differential unit has been fulfilled by simulation in Lab view software, and the results have been discussed in detail. The proposed model helps in weight reduction, ride quality enhancement, part reduction, engine load reduction and decreasing the number of mechanical parts, lowering the manufacturing costs, and decreasing atmospheric pollution.
