The invention discloses a railway vehicle traction control method and device and a railway vehicle. The method comprises the steps that a traction instruction, load information of each compartment, allowable discharge power feedback information of a power battery of each compartment and equipment power consumption feedback information of each compartment are obtained; calculating the required traction power of each carriage based on the traction instruction and the load information, and calculating the available traction power of each carriage based on the allowable discharge power feedback information and the equipment power consumption power feedback information; based on the required traction power and the available traction power of each carriage, whether power short supply exists in any carriage and/or the whole vehicle or not is determined, and when power short supply exists, at least one of the first measure, the second measure and the third measure is executed. According to the scheme, smooth traction operation of the vehicle under the extreme fault working condition can be guaranteed, and the vehicle can timely arrive at the next station to clear passengers and return to the garage for maintenance.

    一种轨道车辆牵引控制方法、装置和轨道车辆,该方法包括:获取牵引指令、每节车厢的载荷信息、每节车厢的动力电池的允许放电功率反馈信息以及每节车厢的设备耗电功率反馈信息;基于牵引指令和载荷信息计算每节车厢的需求牵引功率,并基于允许放电功率反馈信息和设备耗电功率反馈信息计算每节车厢的可用牵引功率;基于每节车厢的需求牵引功率和可用牵引功率确定任意车厢和/或整车是否存在功率的供不应求,当存在功率的供不应求时,执行第一措施、第二措施和第三措施这三者中的至少一者。该方案能够保障在极端故障工况下车辆顺利牵引运行,及时到下一站清客以及返库维修。
