The invention discloses an economical upshift control method and system for a hybrid electric vehicle and the vehicle, and the upshift control method comprises the steps that when the input torque is kept stable or slowly increased, a first clutch and a second clutch in the economical upshift process alternately work along with the change of gears; according to the continuity of the economical upshift process of the hybrid electric vehicle, a first clutch and odd gears are correspondingly arranged, and a second clutch and even gears are correspondingly arranged; when one clutch is engaged and transmits power, the other clutch is disengaged and does not transmit power; according to the power system, the transmission with the double clutches is adopted, in the upshift process, the current clutch is gradually separated, the target clutch is gradually connected, power is not interrupted in the gear shifting process, it is guaranteed that the torque of the output shaft of the transmission does not fluctuate, power transmission is smooth and free of impact, and the driving performance of a vehicle is effectively improved.

    本发明公开了一种混合动力汽车经济性升挡控制方法、系统及汽车,其中,升挡控制方法包括:输入转矩在保持稳定或缓慢增加时,处于经济性升档过程中的第一离合器和第二离合器随着挡位的变化交替工作;根据混合动力汽车经济性升挡过程的连续性,将第一离合器与奇数挡位相应设置,第二离合器与偶数挡位相应设置;当一个离合器接合并传递动力时,另一个离合器分离,不传递动力;本发明的动力系统采用双离合器的变速器,在升挡过程中,当前离合器逐渐分离,目标离合器逐渐接合,实现换挡过程动力无中断,保证变速器的输出轴转矩不出现波动,动力传递平顺无冲击,有效提升车辆的行驶性能。
