摘要
针对四轮独立驱动汽车在转向和变速行驶中各车轮输出转矩和功率变化规律问题,建立自然坐标系下的整车动力学模型,考虑车辆转向时的轴荷转移,并在Matlab/Simulink环境下对低速行驶的工况进行仿真。结果表明,在低速转向和变速工况行驶中,各轮的输出转矩和功率有所不同,但与理论变化趋势相吻合,进一步为各轮转矩控制策略的研究奠定基础。
Four-wheel drive vehicles for each wheel independently torque and power output variation problems in steering and speed driving,vehicle dynamics model established under natural coordinates,considering the effects of axle load transfer and in Matlab/Simulink environment for low-speed driving conditions simulated.The results show that in low-speed steering and speed driving conditions,each wheel torque and power output are different,but the theory is consistent with the trend, and further lay the foundation for the study of each wheel torque control strategy.
