Design of Auxiliary Electric Driving System in Rear Wheels of Vehicles

To find a proper method in the limited interior space to propel the vehicle by a power-assisted way and to improve the vehicle performance, a catamaran car concept is introduced in this paper to apply power-assisted drive on rear wheels and to achieve the energy sharing. The model is constructed in the GT-suit simulation condition to perform the simulation and the results are also analyzed. The results indicate that acceleration and gradeability can be significantly improved by utilizing catamaran car method to apply power-assisted drive on rear wheels, thereby verifying the feasibility of this design solution.
