纯电动汽车双电机耦合驱动系统的模式切换研究
Mode switching of dual motors coupled driving on pure electric vehicle
摘要
Abstract
The operational mode for the dual motors of coupled drive system used in pure electric vehicle is studied.The planetary coupling drive systems were divided into the low-speed single motor and high-speed dual-motor mode based on the structure and working principles.The reasonable and efficient con-trol strategy can improve the efficiency of the drive system using a single motor drive or dual-motor cou-pling drive in meeting the requirements of the premise.Controling the brake in the planetary coupling de-vice for mode switching from the single motor drive to the dual-motor coupling drive based on the maxi-mum speed of the vehicle can improve the system efficiency.They were verified by building simulation models in Matlab/Simulink environment.The test results show that this control strategy can control the double motor for effective state according to the drive's needs.The mode switching from the single motor drive to the dual-motor coupled drive is achieved and satisfies the performance requirements of the vehi-cle.关键词
