[0048] It should be noted that the application scenarios described in the above embodiments are merely examples. The services and scenarios described in the embodiments of the present invention are for more clearly explaining the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those of ordinary skill in the art can know that with the evolution of the system and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems. The following will be described in detail respectively.

[0049] It should be noted that the description order of the following embodiments does not serve as a limitation on the preferred order of the embodiments. The following will describe in detail the vehicle light projection adjustment method.

[0050] Please refer to Figure 1 , Figure 1 which is a schematic flowchart of the vehicle light projection adjustment method provided by the embodiments of the present invention.

[0051] As Figure 1 shown, the method includes the following steps S110 to S140.

[0052] S110. Obtain the current navigation information of the first vehicle; wherein, the navigation information includes the current driving position and driving speed of the first vehicle.

[0053] Specifically, the navigation information is the guiding information for the first vehicle to drive on the road surface. The navigation information includes the current driving position and driving speed of the first vehicle. The current driving position of the first vehicle can be obtained from the positioning system in the first vehicle. This positioning system can be the positioning system of the user's mobile phone or the positioning system equipped by the first vehicle itself. At the same time, the current driving position of the first vehicle can also be obtained from the image captured by the camera equipped by the first vehicle itself. The current driving speed of the first vehicle can be obtained from inside the first vehicle, such as the rotation speed of the first vehicle's tires, or from the positioning system in the first vehicle or the positioning system in the user's mobile phone. That is to say, the method of obtaining the current navigation information of the first vehicle can be selected according to actual applications, and the present application does not make specific limitations.

[0054] S120. Determine the first light projection area of the first vehicle according to the current driving position of the first vehicle.

[0055] In this embodiment, the first light projection area is located in front of the first vehicle. The driving positions include positions when driving at intersections and positions when driving at non-intersection areas. That is to say, the first light projection area includes two types of first projection areas. That is, there is a first projection area corresponding to the position where the first vehicle is driving at an intersection, and there is also a first projection area corresponding to the position where the first vehicle is driving at a non-intersection area. Therefore, after obtaining the current navigation information of the first vehicle, the first light projection area of the first vehicle can be determined through the current driving position of the first vehicle in the navigation information, so as to illuminate the first light projection area in front of the first vehicle.

[0056] In other inventive embodiments, such as Figure 2 shown, step S120 includes steps S121 and S122.

[0057] S121. If the first vehicle is currently in a turning state, obtain the current turning information of the first vehicle;

[0058] S122. Determine the first light projection area of the first vehicle according to the current driving position and turning information of the first vehicle.

[0059] In this embodiment, the turning state includes any one of a turning state, a U-turn state, and a lane-changing state. Different turning states of the first vehicle currently located will inevitably cause changes in the lighting area required by the user. At this time, simply determining the first light projection area of the first vehicle through the current driving position of the first vehicle cannot meet the user's needs. Therefore, in the process of determining the first light projection area of the first vehicle by using the current driving position of the first vehicle, it is also necessary to determine whether the first vehicle is in a turning state. If the first vehicle is in a turning state, at this time, it is necessary to jointly determine the first light projection area of the first vehicle according to the current driving position and turning information of the first vehicle; if the first vehicle is not in a turning state, at this time, the first light projection area can be set as shown in Figure 4 or Figure 5 shown light projection areas, that is, the light projection area at a non-intersection and the light projection area at an intersection. Among them, the light projection area at the intersection is the entire intersection area as the first light projection area.

[0060] In other inventive embodiments, such as Figure 3 shown, step S122 includes steps S1221 and S1222.

[0061] S1221. If the first vehicle is not currently driving at an intersection, determine the first light projection area of the first vehicle according to the current driving lane and turning information of the first vehicle;

[0062] S1222. If the first vehicle is currently driving at an intersection, determine the first light projection area of the first vehicle according to the current intersection category and turning information of the first vehicle.

[0063] In this embodiment, after obtaining the current driving position of the first vehicle, it is necessary to first determine whether the first vehicle has currently reached the intersection position. If the first vehicle has not reached the intersection position, it is also necessary to determine whether the first vehicle is currently in a turning state. If the first vehicle is not currently in a turning state, it can be determined that the lane on which the first vehicle is currently driving is a straight lane, and then the first light projection area can be determined as shown in Figure 4 the light projection area shown. At this time, the first light projection area matches the shape of the lane on which the first vehicle is currently driving; if the first vehicle is in a turning state, it is also necessary to confirm whether the turning state is one of the turning state, U-turn state, and lane-changing state. For example, if it is confirmed that the turning state is the turning state, it can be determined that the road on which the first vehicle is currently driving is a curved road, that is, the lane on which the first vehicle is currently driving is a curved lane, and then the first light projection area can be determined as shown in Figure 7 the light projection area shown. At this time, the first light projection area also matches the shape of the lane on which the first vehicle is currently driving; for another example, if it is confirmed that the turning state is the lane-changing state, it can be defaulted that the lane on which the first vehicle is currently driving is a straight lane, and then the first light projection area can be determined as shown in Figure 9 the light projection area shown, that is, Figure 4 an additional identical light projection area is added to the light projection area shown, and this light projection area is located on the driving lane after the lane change.

[0064] If the first vehicle reaches the intersection position, it is also necessary to determine whether the first vehicle is currently in a turning state. If the first vehicle is not currently in a turning state, it is necessary to determine the type of the current intersection, that is, whether the current intersection is a crossroads or a fork. If the current intersection is a crossroads, the first light projection area can be set as shown in Figure 5 the light projection area shown, that is, the light projection area of the intersection is the entire intersection area as the first light projection area; if the current intersection is a fork, the first light projection area can be set as shown in Figure 6 the light projection area shown. This area is an additional light projection area of the right driving lane on the basis of the light projection area in front of the vehicle; if the first vehicle is currently in a turning state, it is also necessary to determine whether the current intersection is a crossroads. If it is a crossroads, the first light projection area can be directly set as shown in Figure 8 the light projection area shown, that is, Figure 8 the light projection area in Figure 5It is obtained by horizontally moving on the basis of the light projection area of the first vehicle towards the turning position of the first vehicle.

[0065] S130. Adjust the first light projection area according to the current driving speed of the first vehicle to obtain the second light projection area of the first vehicle.

[0066] In this embodiment, after determining the first light projection area of the first vehicle, it is also necessary to adjust the first light projection area according to the current driving speed of the first vehicle, so as to improve the safe driving of the vehicle at night. As Figure 10 shown, Figure 10 Among them, the longest light projection area is on the far left, the middle one is the second longest, and the shortest light projection area is on the far right. Among them, the difference between the second light projection area and the first light projection area is only the length. The length of the second light projection area can be longer than that of the first light projection area, can be shorter than that of the first light projection area, or can be equal to that of the first light projection area. At the same time, in the process of adjusting the first light projection area according to the current driving speed of the first vehicle, if the current speed is too fast, the length of the first light projection area can be shortened to remind the driver that the driving speed is too fast, and then remind the driver to reduce the vehicle speed. Or the length of the first light projection area can also be lengthened to ensure that the driver can timely discover the obstacle ahead, so as to ensure that the driver can timely decelerate and avoid traffic accidents; if the current speed is slow, the length of the first light projection area can be shortened to remind the driver that the driving speed is too slow, and then remind the driver to increase the vehicle speed to avoid the vehicle creeping. Or the length of the first light projection area can also be increased to ensure that the driver can timely discover the obstacle ahead, so as to ensure that the driver can timely decelerate and avoid traffic accidents.

[0067] S140. If there is an obstacle around the first vehicle, adjust the second light projection area according to the positional relationship between the first vehicle and the obstacle to obtain the third light projection area of the first vehicle.

[0068] In this embodiment, the obstacle may be at least one of pedestrians, animals, motor vehicles, and non-motor vehicles around the vehicle. The obstacles around the first vehicle can be detected by the vehicle's own radar or obtained by image acquisition using the camera configured on the vehicle. The positional relationship is the position information of the obstacles around the vehicle, such as in front of the vehicle, on the left side, on the right side, or behind the vehicle. After determining that there are obstacles around the first vehicle and obtaining the positional relationship between the first vehicle and the obstacle, the second light projection area can be adjusted according to the positional relationship to obtain the third light projection area of the first vehicle. At this time, there may or may not be an obstacle in the third light projection area of the first vehicle. For example, if the obstacle is a vehicle in the front, i.e., the second vehicle, then there is no such obstacle in the third light projection area, and in this case, light interference with the vehicle in front can be avoided. If the obstacle is a pedestrian, animal, or non-motor vehicle and the obstacle is in a deviated position in the front, the third light projection area can be extended to the position where the obstacle is located, thereby giving an early warning to the driver and avoiding traffic accidents.

[0069] In other embodiments of the invention, before adjusting the second light projection area according to the positional relationship between the first vehicle and the obstacle to obtain the third light projection area of the first vehicle, the following steps are further included: determining the positional relationship between the first vehicle and the second vehicle according to the light projection area of the second vehicle.

[0070] In this embodiment, the obstacle is the second vehicle in motion. The second vehicle is in an adjacent lane to the current driving lane of the first vehicle, and the distance between the second vehicle and the first vehicle is relatively close. At this time, the light projection area of the second vehicle can be image-captured, and the current positional relationship between the second vehicle and the first vehicle can be recognized from the captured image.

[0071] In other embodiments of the invention, as Figure 11 shown, step S140 includes steps S141 and S142.

[0072] S141. If the positional relationship is that the second vehicle is in front of the first vehicle and the first vehicle and the second vehicle are in the same driving lane, obtain the first separation distance between the first vehicle and the second vehicle;

[0073] S142. Adjust the second light projection area according to the first separation distance to obtain the third light projection area of the first vehicle.

[0074] In this embodiment, the obstacle is a second vehicle in motion. The second vehicle is directly in front of the first vehicle. At this time, if illumination continues in the second light projection area, it is possible that the length of the second light projection area is too long, resulting in the second vehicle being in the second light projection area, causing interference to the driver in the second vehicle. At this time, if the first vehicle is traveling at a high speed and the second vehicle suddenly brakes while the following distance of the first vehicle is insufficient, a rear-end collision is extremely likely to occur. Therefore, in order to avoid interference to the second vehicle caused by the second light projection area and at the same time remind the driver of the first vehicle to reasonably control the vehicle speed, it is also necessary to obtain the first separation distance between the first vehicle and the second vehicle, that is, the following distance of the first vehicle, and then shorten the length of the second light projection area through the first separation distance, thereby obtaining the third light projection area of the first vehicle.

[0075] For example, as Figure 12 shown, when there is no vehicle directly in front of the first vehicle, the second light projection area does not need to be adjusted and the leftmost light projection area can be directly adopted. Figure 12 If there is a vehicle directly in front of the first vehicle and the following distance of the first vehicle is far, the middle light projection area in Figure 12 can be adopted; if there is a vehicle directly in front of the first vehicle and the following distance of the first vehicle is close, the rightmost light projection area in Figure 12 can be adopted.

[0076] In other inventive embodiments, as Figure 13 shown, step S140 includes steps S143, S144, S145, and S146.

[0077] S143. If the positional relationship is that the second vehicle is in front of the first vehicle and the current lane of the first vehicle is adjacent to the lane of the second vehicle, determine whether the first vehicle is in a lane-changing state.

[0078] S144. If the first vehicle is currently in a lane-changing state, determine whether the first vehicle changes lanes into the lane of the second vehicle.

[0079] S145. If the first vehicle changes lanes into the lane of the second vehicle, determine the second separation distance between the first vehicle and the second vehicle after the lane change.

[0080] S146. Adjust the second light projection area according to the second separation distance to obtain the third light projection area of the first vehicle.

[0081] In this embodiment, to ensure the safe driving of the vehicle at night, if the obstacle is a second vehicle in motion, the second vehicle is located in front of the first vehicle on the right or left, and at the same time, the driving lane of the second vehicle is adjacent to the driving lane of the first vehicle. At this time, if the first vehicle wants to change lanes, it is necessary to adjust the second light projection area of the first vehicle again after determining that the first vehicle is in the lane-changing state, so that the adjusted light projection area can better provide safety services for the first vehicle. If the first vehicle changes lanes to the driving lane of the second vehicle, determine the second separation distance between the first vehicle and the second vehicle after the lane change, that is, the following distance of the first vehicle after the lane change, and then adjust the second light projection area according to the second separation distance, that is, a projection area of the first vehicle after the lane change can be added to the second light projection area, and finally obtain the light projection area as shown in Figure 14 ; if the first vehicle does not change lanes to the driving lane of the second vehicle, the second projection area can be directly horizontally moved to the driving lane of the first vehicle after the lane change.

[0082] In other embodiments of the invention, as shown in Figure 15 , step S140 includes steps S1401, S1402, and S1403.

[0083] S1401. If the position relationship is that the second vehicle is in front of the first vehicle and the current driving lane of the first vehicle is adjacent to the driving lane of the second vehicle, determine whether the first vehicle is in an overtaking state according to the current driving speed of the first vehicle;

[0084] S1402. If the first vehicle is in an overtaking state, obtain the number of second vehicles in the driving lane adjacent to the current driving lane of the first vehicle;

[0085] S1403. Adjust the second light projection area according to the number of second vehicles in the driving lane adjacent to the current driving lane of the first vehicle to obtain the third light projection area of the first vehicle.

[0086] In this embodiment, the obstacle is a second vehicle in motion. To more comprehensively ensure the safe driving of the vehicle at night, when the second vehicle is located in front of the first vehicle on the right or left, the driving lane of the second vehicle is adjacent to the driving lane of the first vehicle, and the number of second vehicles is at least one, when it is determined that the first vehicle is about to overtake, to ensure the safe overtaking of the first vehicle, at this time, it is necessary to first obtain the number of second vehicles in the driving lane adjacent to the current driving lane of the first vehicle, then obtain the position relationship between the first vehicle and each second vehicle, and then adjust the second light projection area according to the position relationship between the first vehicle and each second vehicle to obtain a light projection area that meets the safe overtaking of the first vehicle, that is, the third light projection area.

[0087] For example, as Figure 16 shown, when there are two second vehicles in the left lane of the first vehicle, one is located in the front left and the other is traveling side by side with the first vehicle, and at the same time, there is a second vehicle in the front right in the right lane of the first vehicle, the position relationship between the first vehicle and each second vehicle can be obtained at this time, and then the vehicle distance between the two second vehicles in the left lane can be determined. Furthermore, based on the second light projection area, according to the light projection within this vehicle distance, a light projection area as Figure 16 shown can be formed. Among them, the present application can also add a light projection again in the right lane according to the front-to-back distance between the first vehicle and the right vehicle to further ensure timely detection of obstacles on the right side.

[0088] In other embodiments of the invention, as Figure 17 shown, step S140 includes steps S1404 and S1405.

[0089] S1404. If the position relationship is that the current driving lane of the first vehicle is adjacent to the driving lane of the second vehicle, determine whether the first vehicle is currently driving at an intersection;

[0090] S1405. If the first vehicle is currently driving at an intersection, adjust the second light projection area according to the light projection area of the second vehicle to obtain the third light projection area of the first vehicle.

[0091] In this embodiment, the obstacle is a second vehicle in motion. When the driving lane where the second vehicle is located is adjacent to the current driving lane of the first vehicle and the distance between the first vehicle and the second vehicle is relatively close, in order to further improve night driving safety, it is also necessary to further determine whether the first vehicle is currently driving at an intersection and whether this intersection is an intersection where multiple lanes converge into one driving lane. If so, in order to avoid the overlap of the second light projection area of the first vehicle and the light projection area of the second vehicle, which may cause interference to the second vehicle, at this time, it is necessary to obtain the light projection area of the second vehicle, and then adjust the second light projection area according to the light projection area of the second vehicle to obtain a light projection area that does not overlap with the light projection area of the second vehicle, that is, the third light projection area.

[0092] For example, as Figure 18 shown, when the first vehicle is currently driving at an intersection where three lanes converge into one lane, the first vehicle is in the middle lane, and there is a second vehicle in each of the two side lanes. At this time, in order to avoid the overlap of the second light projection area of the first vehicle and the light projection areas of the second vehicles on both sides, the width of the second light projection area can be reduced while the length is increased, so as to obtain a light projection area that does not overlap with the light projection areas of the second vehicles, that is, the third light projection area.

[0093] In other embodiments of the invention, after step S1405, the method further includes the step of: setting a first warning area at an edge position of the light projection area of the second vehicle.

[0094] In this embodiment, in order to remind the driver in the second vehicle in the lane adjacent to the current driving lane of the first vehicle and the driver in the first vehicle, the present application can also set a first warning area at the edge position of the light projection area of the second vehicle, that is, an additional light projection area is added, and safety warning words such as "vehicle merging" are projected in this light projection area, while better ensuring the safe driving of the vehicle at night. For example, the first warning area can be located Figure 19 in front of the light projection area of the right vehicle in

[0095] In other embodiments of the invention, after step S140, the method further includes the step of: setting a second warning area at an edge position of the third light projection area according to the category of the third light projection area.

[0096] In this embodiment, in order to further improve the safety of the vehicle during night driving, the present application can also set a second warning area at the edge of the light projection area when the vehicle is driving to an intersection, there is a vision blind area in front of the intersection, and when the vehicle changes lanes and overtakes when there are obstacles around the vehicle, so as to remind the driver in the vehicle to drive safely. For example, when the vehicle drives to an intersection, in order to remind nearby obstacles (other vehicles, pedestrians and non-motor vehicles) to pay attention to safety, a warning area as shown in Figure 20 can be set at an edge position close to the obstacle and in the light projection area of the vehicle.
