Embodiment 1

[0033] The present embodiment relates to a kind of license plate automatic cleaning device, by figure 1 As shown, it includes a controller 1, an engine start detection unit 2 connected to the signal input terminal of the controller 1, a smoke concentration detection unit 3, a vehicle speed detection unit 4, a smoke concentration threshold memory 5, and a signal output terminal connected to the controller 1. The license plate cleaner 7 for cleaning the license plate 6.

[0034] Wherein, the controller 1 can be a vehicle ECU, which constitutes the control of the entire cleaning device; the engine start detection unit 2 can use an engine start sensor to obtain an engine start signal and transmit the obtained engine start signal to the controller 1; The concentration detection unit 3 is arranged at the place where the license plate 6 is located, and adopts a smoke concentration sensor to detect the smoke concentration at the place where the license plate 6 is located, and transmit...

Embodiment 2

[0041] This embodiment also relates to a license plate automatic cleaning device, which consists of figure 2 As shown, it is basically the same structure as that shown in Embodiment 1, and the difference is that on the basis of Embodiment 1, the automatic license plate cleaning device also includes a vehicle speed threshold memory 8 connected to the controller 1, in which the vehicle speed threshold is stored; At the same time, a second smoke concentration threshold is stored in the smoke concentration threshold memory 5, and the second smoke concentration threshold is smaller than the first smoke concentration threshold.

[0042] Based on the structure of the automatic license plate cleaning device of this embodiment, its control method is basically the same as that of Embodiment 1, except that in step c, when the vehicle speed is greater than the vehicle speed threshold stored in the vehicle speed threshold memory 8, and the smoke concentration detection unit 3. When the de...

Abstract

The invention provides an automatic license plate cleaning device and a control method thereof. The device comprises a controller, an engine starting detection unit, a smoke concentration detection unit, a smoke concentration threshold value storage, a vehicle speed detection unit and a license plate cleaner arranged at the place where a license plate is located. By arranging the smoke concentration detection unit and the smoke concentration threshold value storage, the smoke concentration at the place where the license plate is located can be monitored in real time; when the detected concentration value is larger than a first smoke concentration threshold value, the license plate cleaner is started automatically, the license plate is cleaned in real time, and the using effect is better.

Description

technical field [0001] The invention relates to the technical field of vehicle component cleaning, in particular to an automatic license plate cleaning device; meanwhile, the invention also relates to a control method for the license plate automatic cleaning device. Background technique [0002] As air pollution becomes more and more serious, the number of smoggy cities continues to increase. The license plates of vehicles that have been left for a long time are often covered with dust of different thicknesses, which can easily cause the license plate to be blocked. Usually, people can wipe the dust on the license plate and the vehicle body with a wiping mop to prevent the blocking of the vehicle license plate. However, during the driving process of the vehicle, especially when the vehicle is driving on complex and harsh road conditions such as dirt roads and gravel roads, the vehicle is in a large amount of dust, and under the action of aerodynamics, a large amount of dust ...
