The invention provides a control method for judging the running state of a fuel vehicle, which comprises the following control steps of: 1, judging the running state of the vehicle, namely judging whether the vehicle is in a high-speed running state or a climbing road running state or not through an algorithm by taking the speed, acceleration and road condition information of the vehicle as input parameters; 2, the SOC of the battery is adjusted, specifically, a, when the vehicle is judged to run at a high speed, the SOC of the battery is adjusted to be within the range of 40% by controlling a BMS; and b, when the vehicle is judged to run on a climbing road, the SOC of the battery is adjusted to be within the range of 60% by controlling the BMS. According to the present invention, by adjusting the SOC level of the battery to a lower level, the load and pressure of the battery can be reduced, the loss of the battery can be reduced, and the life of the battery can be prolonged, particularly in a high-speed driving state, and the long-life battery means less maintenance and lower replacement cost, thereby improving the sustainability of the whole vehicle.

    本发明提供了一种判断燃料车辆运行状态控制方法,包括以下控制步骤:步骤一、判断车辆运行状态:以车辆速度、加速度和路况信息作为输入参数,通过算法判断车辆是否处于高速行驶状态或爬坡公路行驶状态;步骤二、调整电池SOC:a.当车辆判断为高速行驶时,通过控制BMS调整电池SOC至40%范围;b.当车辆判断为爬坡公路行驶时,通过控制BMS调整电池SOC至60%范围。通过将电池的SOC水平调整至较低水平,特别是在高速行驶状态下,可减轻电池的负荷和压力,减少电池的损耗,延长电池的寿命,长寿命的电池意味着更少的维护和更低的替换成本,从而提高了整体车辆的可持续性。
