1. a vehicle gas supply system, said system comprises:

  • air pump, air pipe (3), the first pressure controller (4) and the second pressure controller (5), gas cylinder (6), gas pump power source, it is characterized in that;

    said air pump is the first air pump (1) and the second air pump (2), said gas pump power source is the first gas pump power source (9) and the second gas pump power source (10);

    Said the first air pump (1) is connected with gas cylinder (6) by air pipe (3) respectively with the second air pump (2), and said gas cylinder (6) is provided with freeing pipe (7);

    Through wire (8) respectively with said the first pressure controller (4) and said the second pressure controller (5) and be connected with the first gas pump power source (9) and the second gas pump power source (10) respectively, said the first gas pump power source (9) that makes the first pressure controller (4) control said the first air pump (1) starts or stops, and said the second gas pump power source (10) that said the second pressure controller (5) is controlled said the second air pump (2) starts or stops;

    If the Y4 of limit value atmospherically of the first pressure controller (4), lower limit X4;

    The Y5 of limit value atmospherically of the second pressure controller (5), lower limit X5, has Y4>

    Y5>

    X4>

    X5;

    Air pump is initially halted state;

    When air pressure is during lower than X5, the second air pump (2) is started working;

    When air pressure is during lower than X4, the first air pump (1) is started working;

    In the time that air pressure exceedes Y5, the second air pump (2) quits work;

    In the time that air pressure exceedes Y4, the first air pump (1) quits work;

    Air pressure is between Y4 and X4, if air pressure is less than X4 before, and the first air pump (1) work, if air pressure is higher than Y4 before, the first air pump (1) quits work;

    Air pressure is between Y5 and X5, if air pressure is less than X5 before, and the second air pump (2) work, if air pressure is higher than Y5 before, the second air pump (2) quits work.
