The invention provides a vacuum pump, a braking system and an automobile, relating to the technical field of automobiles, and aims at improving the traveling safety. The vacuum pump provided by the invention comprises a shell, cover plates and multiple rotors, wherein multiple cavities are formed in the shell, openings are formed in the cavities, and the cover plates cover openings of all the cavities; and each rotor is correspondingly installed in one cavity, and a blade is arranged on each rotor. According to the vacuum pump provided by the invention, all the cavities in the shell are independent from each other, the rotor and the blade in each cavity do not affect the rotors and the blades in other cavities during rotation, when the rotor and the blade in a certain cavity fail, the rotors and the blades in other cavities can be used for providing a vacuum source for a brake booster, so as to ensure the normal use of the braking system, and the traveling safety can be improved.
