[0044] First, the application scenarios to which this application is applicable are introduced. The embodiments provided in this application are applicable to the field of vehicle lighting technology, and in particular, relate to a lighting method, device, electronic device and storage medium for a vehicle trunk.

[0045] Currently, existing trunk lighting may block items in the trunk or dazzle passengers as the rear seats move, thereby affecting the lighting effect. To solve the above problems, traditional trunk lighting generally installs a transmission mechanism in the trunk to control the movement of the lighting equipment, but this invisibly increases the failure rate of the lighting equipment, lighting costs and equipment maintenance costs.

[0046] Based on this, the embodiments of the present application provide a lighting method, device, electronic device and storage medium for the trunk of a vehicle. The embodiments provided by the present application solve the technical problems of the prior art trunk lighting, such as the phenomenon that light blocks items in the trunk or dazzles passengers, the high failure rate of lighting equipment, and the high lighting cost and equipment maintenance cost. The embodiments provided by the present application solve the problem of light blocking items in the trunk or dazzling passengers caused by trunk lighting through a new layout of multiple lighting equipment, and reduce the lighting cost and the maintenance cost of lighting equipment.

[0047] Figure 1FIG1 shows a flowchart of a vehicle trunk lighting method provided by an embodiment of the present application. Figure 1 As shown, the vehicle trunk lighting method includes the following steps:

[0048] S101. After adjusting the rear seats of the vehicle, obtain position change data and angle change data of the rear seats before and after the adjustment.

[0049] In this step, the vehicle trunk lighting method of the embodiment of the present application is applied in a lighting system. Figure 2 As shown, Figure 2 FIG. 1 shows a structural block diagram of a lighting system provided by an embodiment of the present application. Figure 2 As shown, the lighting system 20 includes a first lighting device 1, a second lighting device 2, an angle sensor 3, a position sensor 4 and a vehicle controller 5. The first lighting device 1, the second lighting device 2, the angle sensor 3 and the position sensor 4 are all communicatively connected to the vehicle controller 5. The vehicle controller 5 can be, but is not limited to, installed near the head instrument panel of the vehicle.

[0050] In the above, the angle sensor 3 is used to collect the angle change data of the rear seat before and after adjustment;

[0051] In the above, the position sensor 4 is used to collect the position change data of the rear seat before and after adjustment;

[0052] In the above, the vehicle controller 5 is used to determine whether the rear seats fall into the lighting range of the first lighting device 1 based on the position change data and the angle change data, and when the rear seats do not fall into the lighting range of the first lighting device 1, send a lighting turn-on signal to the first lighting device 1 and send a lighting turn-off signal to the second lighting device 2; when the rear seats fall into the lighting range of the first lighting device 1, send a lighting turn-on signal to the second lighting device 2 and send a lighting turn-off signal to the first lighting device 1.

[0053] It can be understood that the first lighting device 1 in the embodiment provided in the present application is installed on the top of the trunk, and the second lighting device 2 is installed on the top of the seat back of the rear seat, and the lighting and turning off of the first lighting device 1 and the second lighting device 2 are associated with the position change data and angle change data of the rear seat.

[0054] Among them, the first lighting device 1 and the second lighting device 2 in the embodiments provided in this application are devices that provide basic lighting functions for the trunk. Therefore, the models of the first lighting device 1 and the second lighting device 2 can be customized and selected according to different application scenarios.

[0055] From the above, it can be seen that after adjusting the rear seats of the vehicle, the trunk lighting needs to be updated or adjusted again, and the position change data of the rear seats before and after the adjustment needs to be obtained through the position sensor 4, and the angle change data of the rear seats before and after the adjustment needs to be obtained through the position sensor 4.

[0056] S102: Determine whether the rear seats fall within the lighting range of the first lighting device based on the position change data and the angle change data.

[0057] In this step, the embodiment provided in the present application needs to calculate whether the rearmost point of the seat back in the rear seat falls within the lighting range of the first lighting device 1 based on the position change data and the angle change data.

[0058] It can be understood that in the embodiment provided in this application, the first lighting device 1 is represented by C.

[0059] Exemplarily, based on the position change data and the angle change data, the adjusted seat adjustment coordinates of the highest point of the seat back of the rear seat are determined; the boundary coordinates of the lighting range of the first lighting device 1 at the target height are determined, wherein the target height is the height corresponding to the highest point of the seat back; based on the adjusted seat adjustment coordinates and the boundary coordinates, it is determined whether the rear seat falls within the lighting range of the first lighting device 1.

[0060] In the above, in the embodiment provided in the present application, if the horizontal coordinate of the adjusted seat adjustment coordinate is greater than or equal to the horizontal coordinate of the boundary coordinate, it is determined that the rear seat falls within the lighting range of the first lighting device 1; if the horizontal coordinate of the adjusted seat adjustment coordinate is less than the horizontal coordinate of the boundary coordinate, it is determined that the rear seat does not fall within the lighting range of the first lighting device 1.

[0061] Exemplarily, the lighting range of the first lighting device 1 is determined in the following manner:

[0062] Based on the maximum illumination angle corresponding to the first illumination device 1 , the illumination range of the first illumination device 1 is determined.

[0063] The maximum illumination angle corresponding to the first lighting device 1 in the embodiment provided in this application can be represented by θ.

[0064] like Figure 3 As shown, Figure 3 A schematic diagram showing various parameters in a vehicle seat in a vehicle trunk lighting method provided in an embodiment of the present application is shown. Figure 3 In the figure, R is used to represent the riding reference point, which is customized by the seat manufacturer. That is, its coordinate position on the vehicle is set by the car manufacturer.

[0065] Here, A is used to represent the highest point of the seat back of the rear seat; B is used to represent the boundary point of the lighting range of the first lighting device at the target height; L is used to represent the length of the seat back (effective length); T is used to represent the thickness of the seat back (effective thickness); α is used to represent the angle of the seat back (design angle, customized by the seat manufacturer); β is used to represent the reference angle equal to α; γ is used to represent the reference angle that is a complementary angle to β; θ is used to represent the maximum illumination angle corresponding to the first lighting device; Δs is used to represent the position change data fed back by the position sensor; Δδ is used to represent the angle change data fed back by the angle sensor.

[0066] Here, the R coordinate is represented by (x(R), y(R)); the C coordinate is represented by (x(C), y(C)), the backrest design angle α, the seat back effective length L, the seat back effective thickness T, and the maximum illumination angle θ of the lighting device 1.

[0067] Among them, α=β, γ=90°-β, so γ=90°-α.

[0068] Here, as Figure 3 As shown, when the rear seat of the vehicle slides backward or the angle of the seat back is adjusted, the position of A will also change. If A coincides with B or is on the right side of B, it is determined that the rear seat falls within the lighting range of the first lighting device. Otherwise, it is determined that the rear seat does not fall within the lighting range of the first lighting device. Since the height of B (i.e., the y-axis coordinate) is the same as that of B, it is only necessary to determine the x-axis coordinate relationship between A and B.

[0069] Exemplarily, based on the position change data and the angle change data, the adjusted seat adjustment coordinates of the highest point of the seat back of the rear seat are determined, including: determining the horizontal reference length of the seat back mapped in the horizontal direction based on the angle change data and the length of the seat back; determining the seat adjustment horizontal coordinate in the seat adjustment coordinates based on the horizontal reference length, the position change data and the thickness of the seat back.

[0070] In the above, the calculation formula of the seat adjustment horizontal coordinate in the seat adjustment coordinate is:

[0071] x(A)=[x(R)+Δs+L·sin(α+Δδ)+T·sinγ=x(R)+Δs+L·sin(α+Δδ)+T·sin(90-α);

[0072] The calculation formula for the horizontal reference length is:

[0073] P = L·sin(α+Δδ);

[0074] Exemplarily, determining the boundary coordinates of the lighting range of the first lighting device at a target height includes: determining a vertical reference length mapped in the vertical direction of the seat back based on the angle change data and the thickness of the seat back; and determining the horizontal coordinate of the lighting boundary in the boundary coordinates based on the vertical reference length, the lighting position data of the first lighting device, the angle of the seat back, the position change data, and the length of the seat back.

[0075] In the above, the calculation formula of the illumination boundary horizontal coordinate in the boundary coordinate is:

[0076] x(B)=x(C)-tanθ·{y(C)-[y(R)+L·cos(α+Δδ)-T·cosγ]}=x(C)-tanθ·{y(C)-[y(R)+L·cos(α+Δδ)-T·cos(90-α)]};

[0077] The calculation formula for the vertical reference length is:

[0078] Pp=T·cos(90-α);

[0079] S103: If the rear seats do not fall within the lighting range of the first lighting device, control the first lighting device to illuminate the trunk of the vehicle, wherein the first lighting device is installed on the top of the trunk.

[0080] In this step, if Figure 3 As shown, when x(A) is less than x(B), it is determined that the rear seats do not fall within the lighting range of the first lighting device. At this time, it is necessary to control the first lighting device to illuminate the trunk of the vehicle, or switch the lighting state of the trunk of the vehicle to be illuminated by the above-mentioned first lighting device.

[0081] S104: If the rear seat falls within the lighting range of the first lighting device, control the second lighting device to illuminate the trunk of the vehicle, wherein the second lighting device is installed at the top of the seat back of the rear seat.

[0082] In this step, when x(A) is greater than or equal to x(B), it is determined that the rear seats fall within the lighting range of the second lighting device. At this time, it is necessary to control the second lighting device to illuminate the trunk of the vehicle, or switch the lighting state of the trunk of the vehicle to be illuminated by the above-mentioned second lighting device.

[0083] From the above, it can be seen that the calculation method for determining whether the rear seats fall within the lighting range of the first lighting device in the embodiment provided by the present application can determine: whether Δx=x(A)-x(B) is greater than or equal to 0. If Δx=x(A)-x(B)≥0, it is determined that the rear seats fall within the lighting range of the first lighting device; otherwise, it is determined that the rear seats do not fall within the lighting range of the first lighting device.

[0084] in,

[0085] Δx=x(A)-x(B)

[0086] =[x(R)+Δs+L·sin(α+Δδ)+T·sinγ]-{x(C)-tanθ·{y(C)-[y(R)+L·cos(α+Δδ)-T·cosγ]}}

[0087] =[x(R)+Δs+L·sin(α+Δδ)+T·sin(90-α)]-{x(C)-tanθ·}y(C)-[y(R)+L·cos(α+Δδ)-T·cos(90-α)]}};

[0088] Compared with the prior art, the vehicle trunk lighting method provided in the embodiments of the present application obtains position change data and angle change data of the rear seats before and after adjustment after the rear seats of the vehicle are adjusted. Based on the position change data and angle change data, it is determined whether the rear seats fall within the lighting range of a first lighting device. When the rear seats do not fall within or leave the lighting range of the top first lighting device, the first lighting device installed on the top of the trunk is controlled to illuminate the trunk of the vehicle, and the second lighting device is turned off. When the rear seats fall within the lighting range of the first lighting device, the second lighting device installed on the top of the rear seat backrest is controlled to illuminate the trunk of the vehicle, and the first lighting device is turned off to prevent the light from being blocked by the backrest and causing glare to rear passengers. The present application solves the problem of light from trunk lighting blocking trunk items or causing glare to passengers through a novel layout of multiple lighting devices. Moreover, the present application always ensures that one lighting device is lit and the other is turned off while meeting the lighting function, thereby achieving energy saving while extending the service life of the lighting device and reducing the lighting cost and maintenance cost of the lighting device.
