Embodiment 1

[0045] like figure 1 As shown, the vehicle electronic water pump control system provided by Embodiment 1 of the present invention includes a vehicle controller 1 and a water pump control device for controlling the electronic water pump. The electronic water pump includes an impeller and a motor 3 for driving the impeller. The water pump control device It includes a control module 21, the motor is electrically connected to the control module, and the control module is connected to the vehicle controller through a wired control circuit. A wireless transmission channel for transmitting signals is also provided between the vehicle controller 1 and the water pump control device. The vehicle controller is provided with a first wireless transmission module 11, and the water pump control device includes a second wireless transmission channel electrically connected to the control module 21. The transmission module 22, the wireless transmission channel is realized by the first wireless ...

Embodiment 2

[0075] like Figure 8 As shown, the difference between Embodiment 2 of the present invention and Embodiment 1 above is that the vehicle electronic water pump control system further includes a mobile terminal 5, and a third wireless transmission module is provided on the mobile terminal. In this embodiment, the third wireless transmission module adopts the third WiFi module 51, which has the same structure and principle as the first WiFi module 11 and the second WiFi module 22, and the mobile terminal 5 can be mobile terminals such as mobile phones, tablet computers, and vehicle-mounted computers. product.

[0076] The control module 21 sends the operation data of the electronic water pump to the vehicle controller 1 , and at the same time, sends the operation data of the electronic water pump to the mobile terminal 5 through the second WiFi module 22 and the third WiFi module 51 . Of course, the mobile terminal 5 can also obtain the operation data about the electronic water p...

Embodiment 3

[0084] The difference between Embodiment 3 of the present invention and Embodiment 1 above is that the vehicle electronic water pump control system further includes a spare wired control circuit arranged between the vehicle controller 1 and the control module 21 .

[0085] When it is confirmed that both the wired control circuit and the wireless transmission channel fail in step S12 of the first embodiment, the vehicle controller 1 sends an instruction to the control module 21 through the standby wired control circuit, and at the same time, the control module sends the operating status signal of the electronic water pump through The backup wired control circuit is fed back to the vehicle controller. The specific execution process is the same as the description in Embodiment 1, and will not be repeated here.

[0086] The other structures of the third embodiment are the same as those of the first embodiment above, and will not be repeated here.

Abstract

The invention discloses a vehicle electronic water pump control system and a control method thereof. The control system includes a whole vehicle controller and a water pump control device used for controlling an electronic water pump; the electronic water pump includes an impeller and a motor; the water pump control device includes a control module; the motor is electrically connected to the control module; the control module is connected to the whole vehicle controller through a wired control circuit; a wireless transmission channel is arranged between the whole vehicle controller and the water pump control device; the whole vehicle controller is provided with a first wireless transmission module; the water pump control device includes a second wireless transmission module electrically connected to the control module; the wireless transmission channel is realized through the first and second wireless transmission modules; and the wireless transmission channel and the wired control circuit are standby signal transmission channels for each other. The whole vehicle controller can perform double control on the electronic water pump through a wired transmission mode and a wireless transmission mode, so that the stability and response timeliness of the vehicle electronic water pump during working can be enhanced, and using requirements can be better met.

Description

technical field [0001] The present invention relates to the technical field of water pumps, in particular to an electronic water pump control system for vehicles. In addition, the present invention also relates to a control method of the control system. Background technique [0002] At present, with the rapid development of new energy vehicles such as pure electric vehicles and hybrid vehicles, electronic water pumps have been widely used. As an important part of the automobile cooling system, the electronic water pump is mainly used to circulate and cool the engine, turbocharger, battery, drive motor and drive controller. At present, the control board used to control the electronic water pump for vehicles is generally connected to the vehicle controller through a wired circuit. When the electronic water pump needs to be adjusted, the vehicle controller sends a control signal to the control board through the wired circuit, and the control board commands after receiving the c...
