Abstract

Planetary gear sets (PGS) are regarded for their compact structure, high efficiency, and other advantages. They have been successfully implemented in several battery electric vehicles, delivering outstanding performance. This paper examines a dual-motor, dual-PGS four-mode configuration and introduces an innovative matrix-based search method. This approach integrates configuration synthesis, screening, and optimization to identify the most appropriate structure and parameters for the vehicle intended to utilize this configuration. In this process, connection units and structure matrices are defined to complete configuration synthesis. By leveraging the characteristics of PGS and the structure matrices, the speed, torque, and efficiency are calculated for each working mode. Configuration screening is conducted based on the performance requirements of the motor, PGS, and vehicle to preemptively eliminate unqualified configurations. To reduce the computational burden of configuration optimization, a novel energy management strategy is designed that approximates the performance of dynamic programming. This search method is applied to an example vehicle. The results demonstrate that this method can effectively search for the optimal configuration and corresponding parameters under specific requirements.

纯电动汽车双行星齿轮组四模构型综合筛选优化搜索方法

行星齿轮组（PGS）以其结构紧凑、效率高和其他优点而受到重视。它们已成功地应用于多款纯电动汽车，并提供了出色的性能。本文研究了双电机，双pgs四模式配置，并介绍了一种创新的基于矩阵的搜索方法。这种方法集成了配置综合、筛选和优化，以确定最合适的车辆结构和参数，以利用这种配置。在此过程中，定义连接单元和结构矩阵，完成构型综合。利用PGS的特性和结构矩阵，计算了每种工作模式下的速度、扭矩和效率。根据电机、PGS、车辆的性能要求进行配置筛选，先发制人地淘汰不合格配置。为了减少构型优化的计算量，设计了一种近似动态规划性能的能量管理策略。将该搜索方法应用于实例车辆。结果表明，该方法可以有效地搜索出特定要求下的最优配置和相应参数。
