The invention discloses a control system and a vacuumizing system of an electric vacuum system, wherein the control system of the electric vacuum system comprises a pneumatic sensing device for detecting a pneumatic signal in a vacuum source; a signal processor which is connected to the pneumatic sensing device and is used for receiving the pneumatic signal and for converting the received pneumatic signal into an electric signal; and a controller which is connected to the signal processor and is used for receiving the electric signal and for generating a first control command according to the received electric signal, wherein the first control command is used for controlling the electric vacuum pump to carry out vacuumizing treatment on the vacuum source. By virtue of the control system and the vacuumizing system disclosed by the invention, the problem that new energy vehicles cannot be braked under the assistance of vacuum in related technologies is solved.
Description
technical field [0001] The invention relates to the field of electric vacuum pumps, in particular to a control system and a vacuum pumping system of the electric vacuum pump. Background technique [0002] The traditional automobile braking system is the automobile hydraulic braking system. At present, most automotive hydraulic braking systems use vacuum boosters and engines, and rely on the vacuum generated by the engine to perform auxiliary braking, thereby reducing pedal force and improving driving comfort. [0003] For example, if figure 1 As shown, in the related art, the traditional electric vacuum pump control system includes: electric vacuum pump 30', power supply 40', air storage tank 102', vacuum booster 104', delay relay 50' and alarm switch 60'. When in use, after the 12V (direct current) power supply 40' is connected to the electric vacuum pump control system, the electric vacuum pump 30' starts, and the gas storage tank 102' and the vacuum booster 104' are vac...
