The invention provides a gear shifting method and system of a vehicle, and the vehicle. The vehicle comprises an engine and a BSG motor. The gear shifting method of the vehicle comprises the followingsteps: a basic gear shifting point corresponding to the current accelerator pedal opening degree and a BSG motor full-load charging gear shifting point are obtained, and a first vehicle speed corresponding to the BSG motor full-load charging gear shifting point is larger than a second vehicle speed corresponding to the basic gear shifting point; a charging load coefficient corresponding to the current charging torque of the BSG motor is obtained; a final gear shifting point is determined according to the charging load coefficient, the basic gear shifting point and the BSG motor full-load charging gear shifting point, wherein a third vehicle speed corresponding to the final gear shifting point is located between the first vehicle speed and the second vehicle speed; and gear shifting is performed according to the final gear shifting point. According to the gear shifting method of the vehicle, the gear shifting moment can be correspondingly adjusted according to different loads under thecondition that extra loads are added to the engine, so the acceleration performance of the vehicle can be effectively improved, roar of the engine can be effectively reduced, and the driving experience can be improved.

    本发明提供了一种车辆的换挡方法、系统及车辆。其中,车辆包括发动机和BSG电机,车辆的换挡方法包括:获取对应于当前油门踏板开度的基础换挡点和BSG电机全负荷充电换挡点,BSG电机全负荷充电换挡点对应的第一车速大于基础换挡点对应的第二车速;获取对应于BSG电机的当前充电扭矩的充电负载系数;根据充电负载系数、基础换挡点和BSG电机全负荷充电换挡点确定最终换挡点,其中,最终换挡点对应的第三车速位于第一车速和第二车速之间;根据最终换挡点执行换挡。本发明的车辆的换挡方法可以在发动机增加额外负载的情况下,根据负载大小的不同,相应地调整换挡时刻,从而,可以有效改善车辆的加速性能以及降低发动机的轰鸣声,提升驾驶体验。
