Vehicle-mounted oxygen generation system and vehicle

The invention discloses a vehicle-mounted oxygen generation system and a vehicle. The vehicle-mounted oxygen generation system comprises an air storage tank, an oxygen generator and a controller, the air suspension system comprises an air spring, and the air spring is connected to the air storage tank; the oxygen generator is connected to the air storage tank, and the oxygen generator is provided with a waste gas exhaust gas path; the tire pressure system is connected to the waste gas exhaust gas path; the controller is electrically connected with the air suspension system, the oxygen generator and the tire pressure system so as to control starting and stopping of the oxygen generator and inflation and deflation of the air suspension system and the tire pressure system. The air spring and the oxygen generator share one air inlet source, the air inlet source of the tire pressure system comes from waste gas such as nitrogen generated by the oxygen generator, the waste gas of the oxygen generator is effectively utilized, the multiple air inlet sources are integrated to form a common air source system, and the number of parts and occupied space are reduced.
