摘要
进行了三挡电动公交汽车驱动系统构成分析,完成机械自动变速(Automated Manual Transmission,AMT)选换挡机构开发及变速控制单元(Transmission Control Unit,TCU)搭建;对电动公交汽车主驱动电机进行建模与仿真,研究主驱动电机在换挡过程中的控制策略;在建立的机械自动变速AMT系统中,通过数据采集系统,对整车道路测试数据进行采集.整车道路测试数据经统计分析表明,所开发的三挡机械自动变速系统平均换挡时间为1.86 s,换挡冲击度值介于±35 m/s之间,符合乘用舒适度要求,验证了所开发系统选换过程挡控制的可行性.
The driving system layout of 3-gear electric buses was analyzed. The mechanism of the auto mated manual transmission （AMT） was developed and the transmission control unit （TCU） was built. By modeling and simulating of the main driving motor, the shift control strategies for the main driving mo tor were established; The shift process data in the AMT system during the road test were collected via the data-saving system, and analyzed statistically afterwards. The data show that the statistical average shift time is 1.86s and the jerk values are between ± 35 m/s^3 , which conforms to relating jerk standards. Test results validate the feasibility of the AMT system.
