The invention relates to the technical field of automobiles, and particularly discloses a whole automobile braking and electric pile air inlet integrated system of a fuel cell automobile. The whole vehicle braking and electric pile air inlet integrated system of the fuel cell vehicle comprises an electric pile air inlet unit and a whole vehicle braking unit, the electric pile air inlet unit comprises an air compressor, and the air compressor provides vacuum negative pressure for a vacuum booster of the whole vehicle braking unit. A vacuum outlet is formed in the air compressor of the electric pile air inlet unit, the air compressor serves as a vacuum source of the whole vehicle brake unit, the scheme that an electric vacuum pump of a fuel cell vehicle provides vacuum negative pressure for a vacuum booster in the prior art is replaced, use of parts is reduced, and the whole vehicle cost and the whole vehicle weight are reduced; the space of the whole vehicle cabin is saved, the arrangement difficulty of the whole vehicle cabin is reduced, the NVH performance of the whole vehicle is improved, the vacuum degree provided by the air compressor is larger than that provided by the electric control vacuum pump, and then the braking energy efficiency of the whole vehicle braking unit is improved.
本发明涉及汽车技术领域,具体公开了一种燃料电池汽车的整车制动与电堆进气集成系统。燃料电池汽车的整车制动与电堆进气集成系统包括电堆进气单元和整车制动单元,电堆进气单元包括空气压缩机,空气压缩机为整车制动单元的真空助力器提供真空负压。在电堆进气单元的空气压缩机上设置取真空出口,空气压缩机作为整车制动单元的真空源,代替了现有技术中燃料电池汽车的电动真空泵为真空助力器提供真空负压的方案,减少了零部件的使用,降低了整车成本及整车重量,节约了整车机舱的空间,降低了整车机舱的布置难度,改善了整车的NVH性能,且空气压缩机提供的真空度比电控真空泵提供的真空度大,进而提高了整车制动单元的制动能效。
