摘要: 为了改善纯电动汽车驱动系统的性能,开发一种用于纯电动运动多功能汽车的两级自动变速器。应用速比选择原则、换挡控制策略,研究其对于整车性能的影响。仿真结果表明:设计的两挡自动变速器可降低对电机最大转矩和最高转速的需求,减少机械传动噪音,降低变速器输入转速,优化电机的工作转速区间,提高动力传动系统效率。台架试验表明:采用电机主动同步控制技术,在挡位切换过程中能减少动力中断时间,获得较好的换挡品质。

Abstract: A two-speed automatic transmission used in electric sport utility vehicle was developed to improve the performance of the propulsion system of the vehicle. The motor active synchronization were researched using gear ratio choice principle and shift change control algorithm. Simulation results show that the two-speed automatic transmission reduces the maximum torque demand, the motor running speed and mechanical noise, and improves driveline efficiency. The bench tests show that the motor active synchronization control reduces the power interruption time, and helps the transmission achieve a high shifting quality.

Key words: pure electric vehicle, two-speed transmission, fixed ratio reducer, motor active synchronization
