The invention provides a control method and a controller for a vehicle-mounted liquid hydrogen system of a fuel cell automobile, the method is applied to the vehicle-mounted liquid hydrogen system controller, the vehicle-mounted liquid hydrogen system comprises a liquid hydrogen tank, a buffer tank and the vehicle-mounted liquid hydrogen system controller, the buffer tank is used for supplying hydrogen to a fuel cell stack, and the liquid hydrogen tank is used for supplying hydrogen to the buffer tank; the method comprises the steps that when it is detected that a first preset condition is met, the liquid hydrogen tank is started to supply hydrogen to the buffer tank; starting and stopping signals from the fuel cell stack or the whole vehicle are continuously received; and when it is detected that the start-stop signal is a start-up signal, opening the buffer tank to supply hydrogen to the fuel cell stack. According to the method provided by the invention, heat bridges are reduced, and leaked heat is prevented from invading the liquid hydrogen tank.

    本发明提供一种燃料电池汽车的车载液氢系统的控制方法和控制器,方法应用于车载液氢系统控制器,车载液氢系统包括液氢罐、缓冲罐、车载液氢系统控制器,其中,缓冲罐用于向燃料电池堆供应氢气,液氢罐用于向缓冲罐供应氢气;方法包括:在检测到满足第一预设条件时,开启所述液氢罐向所述缓冲罐供应氢气;持续接收来自所述燃料电池堆或整车的开停机信号;在检测到所述开停机信号为开机信号时,开启所述缓冲罐向所述燃料电池堆供应氢气。本发明提供的方法,实现了减少热桥,避免漏热侵入液氢罐。
