The invention discloses a control system and a control method of an electronic vacuum pump and an automobile, and relates to the field of vehicle brake control. The control system comprises a vacuum booster and the electronic vacuum pump; the electronic vacuum pump is connected with the vacuum booster so as to vacuumize the vacuum booster; and the control system further comprises two control circuits, and the control circuits are used for detecting vacuum degree information of the vacuum booster and processing and sending control signals to control on-off of the electronic vacuum pump according to the detected vacuum degree information. And meanwhile, when one control circuit works abnormally, the other control circuit is connected with the electronic vacuum pump. In the invention, reliable and safe performance of vacuumizing the vacuum booster by the electronic vacuum pump is ensured.
