摘要

为了实现集中式驱动系统下电动汽车左右轮驱动转矩的任意分布，具有类似于轮内电机驱动系统的优点，提出了一种新型转矩矢量驱动（TV）驱动桥系统。利用该系统可以很容易地提高车辆的主动安全性和转向机动性。本文首先分析了新型电视驱动桥的结构和转矩分配原理。其次，基于键合图理论建立了较为精确的电视驱动桥系统动态模型，并对系统动态响应特性进行了分析。第三，为了提高系统动态特性的质量，提出了一种基于径向基神经网络滑模控制（RBF-SMC）策略的电视驱动桥系统控制器。最后，搭建了硬件在环（HIL）试验台，通过离线仿真和HIL实验相结合的方法验证了所提RBF-SMC控制策略的有效性。仿真和HIL实验结果均表明，所提出的RBF-SMC控制策略能够有效提高电视驱动桥的系统动态响应质量，使控制的电视驱动桥能够满足实际车辆应用的要求。

Dynamic Characteristic Modeling and RBF-SMC Based Torque Control of a Novel Torque Vectoring Drive-Axle for Electric Vehicles

In order to realize the arbitrary distribution of left/right wheel driving torque for electric vehicles with centralized drive system, which is similar to the advantages of in-wheel motor drive system, a novel torque vectoring (TV) drive-axle system is proposed. With the help of it, the active safety and steering maneuverability of the vehicle can be easily improved. In this paper, the structure and torque distribution principle of the novel TV drive-axle are analyzed first. Second, a relatively accurate system dynamic model of the TV drive-axle is established based on bond graph theory, and the system dynamic response characteristics are analyzed. Third, in order to improve the quality of the system dynamic characteristics, a TV drive-axle system controller based on the radial basis neural network sliding mode control (RBF-SMC) strategy is proposed. Finally, a hardware-in-the-loop (HIL) test bench is built, and the effectiveness of the proposed RBF-SMC control strategy is verified by the combination of off-line simulation and HIL experimental. The simulation and HIL experimental results all demonstrate that the proposed RBF-SMC control strategy can effectively improve the system dynamic response quality of the TV drive-axle, so as the controlled TV drive-axle can meet the requirements of real vehicle application.
