Four Wheel Drive

Electric vehicles are becoming more popular in the market. To be competitive, manufacturers need to produce vehicles with a low energy consumption, a good range and an acceptable driving performance. These are dependent on the choice of components and the topology in which they are used. In a conventional gasoline vehicle, the powertrain topology is constrained to a few well-understood layouts; these typically consist of a single engine driving one axle or both axles through a multi-ratio gearbox. With electric vehicles, there is more flexibility, and the design space is relatively unexplored. In this paper, we evaluate several different topologies as follows: a traditional topology using a single electric motor driving a single axle with a fixed gear ratio; a topology using separate motors for the front axle and the rear axle, each with its own fixed gear ratio; a topology using in-wheel motors on a single axle; a four-wheel-drive topology using in-wheel motors on both axes. Multi-objective optimisation techniques are used to find the optimal component sizing for a given requirement set and to investigate the trade-offs between the energy consumption, the powertrain cost and the acceleration performance. The paper concludes with a discussion of the relative merits of the different topologies and their applicability to real-world passenger cars.

Inherent Advantage

Electric vehicles with four in-wheel motors have its inherent advantage to recover energy because all of its four in-wheel motors can generate electricity energy when braking. For the purpose of study the property of regenerative braking of four-wheel-drive electric vehicles, three traditional distribution strategies of traditional vehicles are adjusted based on the property of in-wheel-motor. A simulation model is established by using Matlab/Simulink and CarSim software, and the simulation is made based on UDDS and 1015 driving cycles. The simulation result shows that, the parallel distribution strategy has the highest regenerative efficiency and regenerative efficiencies of fixed proportion distribution strategy and ideal distribution strategy are almost the same.
