摘要: 四轮独立驱动电动汽车被认为是目前最有发展前景的电动汽车驱动方案之一。由于采用轮毂电机独立驱动,提高系统的可操作性,使得轮胎产生的能量消耗可以独立控制,为汽车节能控制提供了发展潜力。而精确的四轮独立驱动电动汽车轮胎纵、横向滑移能耗模型是实现节能控制的关键与理论基础。针对轮胎纵、横向滑移能耗模型的研究有待进一步深入,针对四轮独立驱动电动汽车的能耗仿真建模的研究也需要进一步完善。针对四轮独立驱动电动汽车轮胎的纵、横向能耗特性,分析其能耗机理,搭建轮胎纵、横向能耗模型;基于滑移能耗模型与电动汽车能耗特性,得到改进的整车能耗模型;在Carsim/Simulink联合仿真环境中,搭建四轮独立驱动电动汽车整车模型与能耗模型,为四轮独立驱动电动汽车能耗研究提供精确可靠的仿真平台;不同工况下的仿真结果证明了考虑横向滑移能耗进行能量优化控制的必要性。

Abstract: Four-wheel independently driving electric vehicles are one of the most promising electric vehicle schemes. Because the wheel motor is driven independently, the operability of system is improved, and the energy consumption generated by the tire can be independently controlled, which provides development potential for control on automobile energy-saving. An accurate model on the tire longitudinal and lateral energy consumption of four-wheel independently driving electric vehicle is the key point while it is the theorical basis for energy saving control. At present, research on the energy consumption models of tire longitudinal and lateral slip, and research on the energy consumption modeling of four-wheel independently driving electric vehicles need to be further improved. Based on the longitudinal and lateral energy consumption characteristics of four-wheel independently driving electric vehicle tires, the energy consumption mechanism of four-wheel independently driving electric vehicles is analyzed. Firstly, the longitudinal and lateral energy consumption models of the tires are developed. And then based on the slip energy consumption model and the electric vehicle energy consumption characteristics, an improved vehicle energy consumption model is introduced. Secondly, in the Carsim / Simulink joint simulation environment, a four-wheel independently driving electric vehicle model and energy consumption model are built, which provides an accurate and reliable simulation platform for the energy consumption research of four-wheel independently driving electric vehicles. Finally, simulation results under different working conditions prove the necessity of energy optimization control considering the energy consumption of lateral slip.

Key words: four-wheel-independently-driving electric vehicles, longitudinal and lateral slip energy consumption, carsim, energy consumption simulation model
