【摘要】 针对轮毂电机驱动电动汽车制动和加速工况时俯仰角较大的问题，对前后转矩分配实现抗制动点头和抗驱动抬头的理论进行了研究。利用Adams/Car多体动力学仿真软件，建立麦弗逊式前悬架及拖曳臂式后悬架模型，分析前后转矩分配规则对抗制动点头率和抗驱动抬头率的影响。通过设计前后转矩分配规则，达到优化抗制动点头性能和抗驱动抬头性能的目标。通过仿真分析，表明所制定的前后转矩分配规则可以实现抗制动点头性能、抗驱动抬头性能的优化。更多还原

【Abstract】 In order to solve the problem of large pitch angle when the in-wheel motor drives the electric vehicle under braking and acceleration conditions, the theory of anti-braking nodding and anti-driving lifting realized by front and rear torque distribution was studied.The Adams/Car multi-body dynamics simulation software was used to establish the MacPherson front suspension and trailing arm rear suspension models, and the influence of front and rear torque distribution rule on anti-braking nodding rate and anti-drive lifting rate was analyzed.By designing the front and rear torque distribution rule, the goal of optimizing the anti-braking nodding performance and anti-driving lifting performance was achieved.Through simulation analysis, it is shown that the formulated front and rear torque distribution rule can realize the optimization of anti-braking nodding performance and anti-driving lifting performance.更多还原
