The invention discloses an automobile vacuum boosting system and a method thereof. A single-chip microcomputer circuit is connected with a power supply voltage detection module, an atmospheric pressure sensor, a vacuum pressure sensor, a CAN signal transceiver module and an alarm signal module. The single-chip microcomputer circuit is connected with a vacuum tank body through a vacuum pump, the vacuum tank body is connected with a vacuum booster, the vacuum pump is connected with the single-chip microcomputer circuit through a current monitoring module, and the vacuum tank body is connected with the vacuum pressure sensor. Power-on self-test is carried out, and if a fault occurs, an alarm is given; an external atmospheric pressure value is outputted, and a normal working mode or a plateauworking mode is selected for entrance; the voltage, current, sensor and pressure value parameters are monitored in real time, if a fault occurs, an alarm is given, and otherwise, circulation work is conducted. The atmospheric pressure sensor and the vacuum pressure sensor are integrated, the power supply voltage and the vacuum pump current are monitored at the same time, and the vacuum pump is controlled to work or stop through a control strategy programmed by the single-chip microcomputer.
