A computer-implemented method of controlling a powertrain of a vehicle, the powertrain including a plurality of fuel cell systems and an electrical energy storage system. The method includes estimating a duration of vehicle stop of the vehicle; determining whether anti-freezing protection is required during the vehicle staying period; and if it is determined that the freeze protection is not required, shutting down the fuel cell system without enabling the freeze protection. If it is determined that the freeze protection is needed, the method may include estimating a threshold time indicative of a time at which a cost of maintaining operation of the fuel cell system exceeds a cost at which the fuel cell system is shut down; and if the estimated duration of vehicle stop expires after the threshold time, shutting down the fuel cell system and enabling the freeze protection.

    一种控制车辆的动力总成的计算机实现的方法,该动力总成包括多个燃料电池系统和电能存储系统。该方法包括:估计该车辆的车辆停留的持续时间;确定在该车辆停留期间是否需要防冻保护;以及如果确定不需要该防冻保护,则关闭该燃料电池系统而不启用该防冻保护。如果确定需要该防冻保护,则该方法可以包括估计指示保持该燃料电池系统操作的成本超过关闭该燃料电池系统的成本的时间的阈值时间;以及如果该车辆停留的估计的持续时间在该阈值时间之后到期,则关闭该燃料电池系统并启用该防冻保护。
