The invention discloses a power system, a control method, a vehicle-mounted controller and a vehicle. The power system comprises a first transmission shaft, a second transmission shaft, a gear shifting mechanism, a speed ratio amplifying mechanism, a main reduction driven gear and a motor. The gear shifting mechanism is arranged on the first transmission shaft, and the first transmission shaft is connected with the motor; the speed ratio amplifying mechanism and the main reduction driven gear are arranged on the second transmission shaft, the speed ratio amplifying mechanism is meshed with the first end of the gear shifting mechanism, and the second end of the gear shifting mechanism is meshed with the main reduction driven gear. According to the power system, the gear shifting mechanism is arranged on the first transmission shaft, the gear shifting mechanism can be prevented from being directly driven by the motor to rotate at a high speed, the power system adapts to the high-rotating-speed working condition of the motor, meanwhile, the gear shifting mechanism is located on the middle shaft, the requirement for the speed reduction transmission center distance can be lowered, the enveloping requirement of the whole power system is lowered, and cost is lowered.
本发明公开了一种动力系统、控制方法、车载控制器及车辆。该动力系统包括第一传动轴、第二传动轴、换挡机构、速比放大机构、主减从动齿轮和电机;所述换挡机构设置在所述第一传动轴上,所述第一传动轴与所述电机相连;所述速比放大机构和所述主减从动齿轮设置在所述第二传动轴上,所述速比放大机构与所述换挡机构的第一端啮合,所述换挡机构的第二端与所述主减从动齿轮啮合。该动力系统通过将换挡机构设置在第一传动轴上,可以避免换挡机构直接在电机带动下进行高速转动,适应电机高转速工况,同时,使换挡机构位于中间轴上,可以降低减速传动中心距要求,降低了整个动力系统的包络和要求,降低成本。
