混合动力汽车驱动电机性能评价体系研究

为了提高混合动力汽车驱动电机系统评价的准确性和客观性,保证驱动电机发挥出最优性能,分别从电机本体设计、电机控制性能和整车行驶循环工况3个层面列出23个评价指标,以驱动电机台架试验和整车计算机仿真平台为评价测试手段,采用多属性决策灰色关联度的评价方法,建立了驱动电机综合性能评价体系.实例证明了该评价体系的完整性和可操作性.

Evaluation Regime of Traction Motor for Hybrid Electric Vehicle

In order to improve the accuracy and objectivity of the traction motor evaluation system of hybrid electric vehicle and make sure of the optimality performance for the motor, 23 evaluating indicators were listed according to the motor body design, performance of motor control and the driving cycle of vehicle. The traction motor performance evaluate system was established with the grey relation degree approach to multiple attribute decision making as evaluation method, and the motor bench test and computer simulation platform as instrument. At last, taking traction motors of hybrid electric bus of FAW as an example, the evaluation system was demonstrated. The results proved that the performance of motor could be determined by the evaluation system.
