轮毂电机四轮独立驱动电动汽车再生制动控制策略
Control Strategy of Regenerative Braking for Four-wheel-drive Electric Vehicles of In-wheel-motor
摘要
Abstract
To increase the continuous driving mileage,a new regenerative braking control strategy of four-wheel-drive electric vehicles of different in-wheel-motors was proposed.The new control strategy based on constraint conditions for the ideal braking force distribution,ECE R13 (Economic commission of europe regultions 13),the different characteristics of the in-wheel-motor and load variation in the front and rear shafts,the characteristics of the battery.Under the condition of stability braking performance,the vehicle's motor and friction braking force can be distributed reasonably,and enhance the utilization factor of in-wheel-motor to recapture more braking energy.A simulation model was built up with the software MATLAB/Simulink and CarSim,and the braking performances were simulated and compared of different braking conditions and control strategies.Simulation results show that the proposed strategy is applicable to four-wheel-drive electric vehicles of different in-wheel-motors and can receive more braking energy comparing with typical strategy,and it has a good performance of braking stability and can obviously improve the driving mileage of electric vehicles.关键词
