The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.

In an aspect of the embodiment of the present application, as shown in fig. 1, a vehicle lamp control device is provided, which includes a controller and a vehicle lamp 160 electrically connected to each other, where the vehicle lamp 160 includes a display panel 110, and the display panel 110 is electrically connected to the controller, so that the controller can correspondingly control the display panel 110 to display a pattern.

Specifically, as shown in fig. 2, the display panel 110 may include a plurality of display areas 130 and non-display areas 120, where the display areas 130 may be multiple, and two adjacent display areas 130 may be separated by the non-display area 120, and each display area 130 may be individually controlled by the controller to be turned on or off correspondingly, where the shapes of at least two display areas 130 in the plurality of display areas 130 are different, so that a plurality of different pattern lighting effects can be presented by using the differentiation of the display areas 130 with different shapes, and correspondingly turning on or off a certain number of display areas 130 by combining.

In order to enable the pattern displayed by the display panel 110 to correspond to the vehicle state information, the controller may acquire the vehicle state information, and then control some or all of the plurality of display areas 130 to be lightened according to the vehicle state information, so that the display areas 130 in the lightened state jointly display the target pattern, and based on the condition that the display areas 130 with different shapes exist, the plurality of display areas 130 are combined to display more complicated and diversified patterns, so that the target pattern can be matched with the vehicle state information, that is, different patterns can be displayed by the lightened lamps 160 to present the current various state information of the vehicle, so that people around the vehicle can quickly acquire the current vehicle state information through the lamps 160, thereby correspondingly taking measures, and being beneficial to improving the driving safety.

As shown in fig. 2, the display panel 110 includes a plurality of display areas 130, and the number and shape of the display areas 130 obtained by dividing the display panel 110 are corresponding to data of each target pattern displayed according to the lighting lamp 160 stored in the database, so that the divided plurality of display areas 130 have display areas 130 with the same shape of a part of the areas and display areas 130 with different shapes of a part of the areas, and thus, all the target patterns in the database can be displayed by combining the plurality of display areas 130.

Since each of the target patterns is displayed by combining a part of the display areas 130 in the lighted state, when the target pattern is replaced, the corresponding display area 130 in the lighted state is replaced. For example, as shown in fig. 3, when the target pattern in fig. 3 needs to be displayed, the dark display area 130 (the display area 130 in the lit state) in fig. 3 is correspondingly lit up in combination, and when the target pattern is switched to the target pattern shown in fig. 4, a part of the display area 130 originally in the lit state is extinguished, a part of the display area remains lit up, and at the same time, a new display area 130 is changed from lit up to lit up.

Alternatively, as shown in fig. 1, the controller includes a general controller 140 and a light controller 150 electrically connected, where the light controller 150 is electrically connected to a lamp 160, the general controller 140 may be an electronic control unit (Electronic Control Unit, ECU) of the vehicle, and the general controller 140 may acquire vehicle state information, and then determine a target pattern matching the current vehicle state information according to the vehicle state information, and send the target pattern to the light controller 150. After receiving the target pattern information sent by the overall controller 140, the light controller 150 correspondingly controls the display area 130 to be lighted in the display panel 110, so that the target pattern matched with the current state of the vehicle is displayed by lighting the vehicle lamps 160. Similarly, when the current state of the vehicle changes, the corresponding target pattern matched with the changed state of the vehicle is displayed.

Optionally, the vehicle light 160 control device further includes a speed sensor for acquiring vehicle speed information, the speed sensor is electrically connected to the overall controller 140, and the overall controller 140 may determine vehicle status information according to the vehicle speed information acquired by the speed sensor.

For example, when the vehicle speed of the vehicle is maintained at a low speed running without braking, the overall controller 140 may acquire that the vehicle is in a low speed running state, correspondingly transmit a target pattern matching the low speed running state to the light controller 150, and then control the display panel 110 by the light controller 150 to display the target pattern (dark area) shown in fig. 3. When the vehicle speed is maintained at a high speed and there is no brake, the overall controller 140 may acquire that the vehicle is in a high speed driving state, correspondingly transmit a target pattern matching the high speed driving state to the light controller 150, and then control the display panel 110 by the light controller 150 to display the target pattern (dark area) shown in fig. 4. Thus, when a person around the vehicle sees the lamp 160 of the vehicle to display the target pattern shown in fig. 3, the person can know that the current vehicle is in a low-speed running state. When the lamp 160 of the vehicle is seen to display the target pattern shown in fig. 4, it is known that the current vehicle is in a high-speed running state.

It should be appreciated that the division between high and low speeds may be reasonably selected according to actual requirements, such as matching a vehicle speed range less than or equal to 80km/h to low speed travel and matching a vehicle speed range greater than 80km/h to high speed travel. Of course, the above is merely an example, and in other embodiments, the vehicle speed may be divided into more sections, so that the vehicle speed is displayed in correspondence with more target patterns.

As shown in fig. 5, the current speed of the vehicle may also be displayed directly by the lamp 160, for example, when the current speed is 72km/h, the display panel 110 may be controlled to display 72.

Optionally, the control device of the vehicle lamp 160 further includes a brake sensor for collecting vehicle brake information, the brake sensor is electrically connected to the master controller 140, and the master controller 140 is used for determining vehicle state information according to the vehicle brake information.

For example, when a brake pedal of the vehicle is depressed, the overall controller 140 may acquire that the vehicle is in a braked state, correspondingly transmit a target pattern matching the braked state to the light controller 150, and then control the display panel 110 by the light controller 150 to display the target pattern (dark area) shown in fig. 6. Thus, when a person around the vehicle sees that the lamp 160 of the vehicle displays the target pattern shown in fig. 6, it is possible to know that the vehicle is currently in a braking state.

In addition, when the controller controls the display area 130 to display, in addition to display and extinction, gray scale, brightness, contrast, etc. of the display area 130 may be controlled and adjusted, thereby making the displayed target pattern more stereoscopic and vivid. For example, as shown in fig. 5, the vehicle lamp 160 may be controlled to display the numerical value 72 and to control the brightness of the display area 130 around the display area 130 of the display 72 to be darker.

Alternatively, the area shape of each display area 130 is polygonal, as shown in fig. 2 to 6, and may include a quadrilateral with the same shape, a quadrilateral with a different shape, a triangle, a pentagon, etc., so that the display areas 130 are greatly different, so that more target patterns can be conveniently combined, and more vehicle state information can be presented.

Optionally, the car light 160 is the vehicle tail lamp, and the main effect of vehicle tail lamp lies in reminding the rear vehicle, therefore, when car light 160 is the vehicle tail lamp, can make the vehicle tail lamp show more target patterns to appear more vehicle state information to the vehicle at rear, make things convenient for the rear vehicle to know the running information of preceding car in time, effectively improve the security of driving.

Alternatively, the display panel 110 is a Mini LED panel, and the Mini LED panel includes a plurality of partitions, each partition serving as one display area 130, that is, each display area 130 may be individually controlled to display by the light controller 150. By using Mini LED panels, the lamps 160 can have a longer life and a higher brightness.

Alternatively, the display panel 110 is an OLED panel, and the OLED panel has a plurality of pixels, and the plurality of pixels are divided into areas, so that the OLED panel has a plurality of areas, each area serves as one display area 130, and the pixels of each display area 130 are controlled by the light controller 150 to be displayed or turned off together.

Optionally, to further enhance the display effect, the vehicle lamp 160 further includes a diffuser element and/or a lamp cover disposed on the light emitting side of the display panel 110. The scattering element can improve the light emitting effect of the car lamp, so that the light emitting is more uniform; the lamp cover is made of a light-transmitting material, so that the lamp cover can provide protection for the vehicle lamp 160 and can smoothly realize light.

In another aspect of the embodiments of the present application, there is provided a vehicle including any one of the above-described lamp control devices. The car lamp 160 can display more complicated and diversified target patterns through the car lamp control device, and then the target patterns can be matched with the vehicle state information, namely, the current various state information of the vehicle can be displayed through the car lamp 160, people around the vehicle can conveniently and rapidly acquire the current vehicle state information through the car lamp 160, measures are correspondingly taken, and the car safety is improved.

The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
