The invention discloses a gas supply method and device for vehicle-mounted gas cylinders and a pneumatic vehicle. When the gas pressure values of gas in the gas cylinders are sequentially obtained, the gas pressure values of the gas in the current N-1 gas cylinders are all smaller than a preset gas pressure threshold value, and the gas pressure value of the gas in the Nth gas cylinder is larger than or equal to the gas pressure threshold value, the Nth gas cylinder is selected as the current gas supply gas cylinder; then calculating the number of current available gas cylinders, and when the number of the current available gas cylinders is smaller than a preset number threshold value, sending out first prompt information; when the condition that the first N-1 gas cylinders cannot supply gas and the Nth gas cylinder can supply gas is detected, the Nth gas cylinder is selected to supply gas to the vehicle so as to automatically switch the gas cylinders for supplying gas, the workload of a driver is reduced, and first prompt information is sent out when the number of the available gas cylinders is too small so as to prompt the driver to supply gas in time and prompt the driver in time when the number of the gas cylinders is small, so that the driving safety is improved. And normal driving is ensured.

    本申请公开了一种车载气瓶的供气方法、装置及气动车辆,通过依次获取气瓶内气体的气压值,当前N‑1个气瓶内气体的气压值均小于预设的气压阈值、且第N个气瓶内气体的气压值大于或等于气压阈值时,选取第N个气瓶作为当前供气气瓶,然后计算当前可用气瓶数量,当当前可用气瓶数量小于预设的数量阈值时,发出第一提示信息;即检测到前N‑1个气瓶无法供气且第N个气瓶可以供气时,选取第N个气瓶为车辆供气,以自动切换供气气瓶,降低驾驶员的工作量,并且在可用气瓶数量过小时发出第一提示信息,以提示驾驶员及时加气,以在气瓶较少时及时提示驾驶员,保证正常驾驶。
