FIG. 1: the structure of a control system of an electronic vacuum pump in the first embodiment is schematically shown.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example one
The control system of the electronic vacuum pump of the embodiment comprises an electronic vacuum pump 1 which is controlled and connected by a VCU vehicle control unit 7, wherein the electronic vacuum pump 1 is sequentially connected with a one-way valve 2, a vacuum cylinder 3 and a vacuum booster 5 through a vacuum pipeline. A line pressure sensor 4 is integrated on a vacuum pipeline between the vacuum cylinder 3 and the vacuum booster 5, and the line pressure sensor 4 is used for detecting the vacuum degree of the vacuum pipeline in real time and transmitting feedback to a VCU vehicle control unit 7 in signal connection with the vacuum pipeline. And meanwhile, an environment pressure sensor 6 for detecting the external environment pressure is arranged on the frame, and the environment pressure sensor 6 is used for transmitting the detected external environment pressure back to the VCU vehicle control unit 7 in signal connection with the VCU vehicle control unit. The VCU vehicle control unit 7 controls the start and stop of the electronic vacuum pump 1 according to a preset control strategy. In whole control system, electron vacuum pump 1 provides the vacuum source, and the vacuum line is used for transmitting the air current, and check valve 2 plays the guard action, and vacuum cylinder 3 is used for storing the vacuum, and vacuum booster 5 provides the braking original paper for whole car.
The strategy for setting the start-stop pressure of the electronic vacuum pump in the embodiment is as follows:
when the environment pressure detected by the environment pressure sensor is alpha, the starting pressure P of the electronic vacuum pumpopenSet to 70% of ambient pressure, i.e. Popen= α × 70%; shut-off pressure P of the electronic vacuum pumpcloseSet to 50% of ambient pressure, i.e. Pclose=α×50%。
The control strategy is applied to the electronic vacuum pump control system in this embodiment, the VCU vehicle controller obtains the external environment pressure detected by the environment pressure sensor, and obtains the start-stop pressure of the electronic vacuum pump according to the pressure value, the VCU vehicle controller compares the vacuum pipe pressure detected by the line pressure sensor with the start-stop pressure of the electronic vacuum pump, and determines whether the vacuum pipe pressure reaches the start pressure of the electronic vacuum pump, if not, the electronic vacuum pump is in a closed state, and when the vacuum pipe pressure reaches the start pressure of the electronic vacuum pump, the electronic vacuum pump starts to work until the pressure value reaches the stop pressure.
The utility model discloses a control system of electron vacuum pump optimizes the control system of electron vacuum pump, and the independent control ware of cancellation integration on a vacuum section of thick bamboo changes into by the direct unified control of VCU to through the control mode of environmental pressure sensor synchronous optimization electron vacuum pump, guarantee that electron vacuum pump can safe effectual work in various ripples areas.
In summary, although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
