The invention discloses an electric vehicle vacuum system, a control method and a vehicle. The electric vehicle vacuum system comprises a vacuum booster, an electric appliance control device and a vacuum pump device. The electric appliance control device comprises a vacuum degree sensor, a vehicle control unit, a first electric control loop and a second electric control loop which are sequentiallyconnected through electric signals. The output end of the first electric control loop and the output end of the second electric control loop are both connected with the input end of the vehicle control unit through electric signals. The vacuum pump device comprises a first vacuum pump device and a second vacuum pump device which are arranged in parallel; the output end of the first electric control loop is further in electric signal connection with the input end of the first vacuum pump device, and the output end of the second electric control loop is further in electric signal connection with the input end of the second vacuum pump device. According to the electric automobile vacuum system, a double-control-loop mode is adopted, the second control loop is started when one loop breaks down, and traveling braking safety is guaranteed.
