The invention discloses an electronic vacuum pump control system suitable for high altitude, relates to the technical field of automobile vacuum boosting, and solves the problems of high cost and unsafe driving caused by control failure of a gear vacuum boosting system in plateau driving of a user in an existing automobile vacuum pump control system. The VCU sends a vacuum pump driving signal to the electronic vacuum pump assembly and sends an alarm signal to the combination instrument according to the current vacuum boosting system state of the vehicle; and sends a brake signal and a brake effectiveness signal according to the brake pedal state; the driving motor is used for receiving a motor torque instruction sent by the vehicle control unit and outputting power; wherein the ESC is used for receiving a wheel speed signal, the combination instrument is used for receiving an alarm signal sent by a vehicle control unit, and the electronic vacuum pump assembly is used for receiving a vacuum pump driving signal sent by the vehicle control unit; and the vacuum degree sensor is used for sending a vacuum degree signal to the vehicle control unit. And the driving safety and comfort of the passenger vehicle can be effectively improved.
