The following will describe in detail.
The following description of the embodiments is not intended to limit the preferred embodiments. The following describes the adjustment method of the vehicle light projection in detail.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for adjusting a light projection of a vehicle according to an embodiment of the application.
As shown in fig. 1, the method includes the following steps S110 to S140.
S110, acquiring current navigation information of a first vehicle; the navigation information comprises the current running position and the running speed of the first vehicle.
Specifically, the navigation information is guiding information of the first vehicle running on the road surface, the navigation information comprises a current running position and running speed of the first vehicle, the current running position of the first vehicle can be obtained from a positioning system in the first vehicle, the positioning system can be a positioning system of a mobile phone of a user or a positioning system equipped with the first vehicle, and meanwhile, the current running position of the first vehicle can also be obtained from an image shot by a camera equipped with the first vehicle; the current running speed of the first vehicle may be obtained from the inside of the first vehicle, such as the tire rotation speed of the first vehicle, or may be obtained from a positioning system in the first vehicle or a positioning system in a mobile phone of a user, that is, the current navigation information of the first vehicle may be obtained and selected according to practical application, which is not limited in the present application.
S120, determining a first light projection area of the first vehicle according to the current running position of the first vehicle.
In this embodiment, the first light projection area is located in front of the first vehicle, and the driving position includes a position where the first vehicle is driving at an intersection and a position where the first vehicle is driving at a non-intersection, that is, the first light projection area includes two types of first projection areas, that is, the first vehicle is driving at the intersection and corresponds to a first projection area, and the first vehicle is driving at the non-intersection and corresponds to a first projection area, so after the current navigation information of the first vehicle is acquired, 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, and thus the first light projection area in front of the first vehicle is illuminated.
In other inventive embodiments, as shown in fig. 2, step S120 includes steps S121 and S122.
S121, if the first vehicle is currently in a steering state, acquiring current steering information of the first vehicle;
s122, determining a first light projection area of the first vehicle according to the current running position of the first vehicle and steering information.
In this embodiment, the steering state includes any one of a turning state, a turning state and a lane changing state, and the difference of the steering states of the first vehicle at present necessarily causes a change of an illumination area required by a user, and at this time, the first light projection area of the first vehicle cannot meet the requirement of the user only by determining the current running position of the first vehicle, so that in the process of determining the first light projection area of the first vehicle by adopting the current running position of the first vehicle, whether the first vehicle is in the steering state needs to be determined, and if the first vehicle is in the steering state, the first light projection area of the first vehicle needs to be determined together according to the current running position of the first vehicle and the steering information at this time; if the first vehicle is not in the steering state, the first light projection area may be set as the light projection area shown in fig. 4 or fig. 5, that is, the light projection area of the non-intersection and the light projection area of the intersection, where the light projection area of the intersection is the whole intersection area as the first light projection area.
In other inventive embodiments, as shown in fig. 3, step S122 includes steps S1221 and S1222.
S1221, if the first vehicle does not run at the intersection currently, determining a first light projection area of the first vehicle according to the current traffic lane and the steering information of the first vehicle;
s1222, if the first vehicle is currently running at the intersection, determining a first light projection area of the first vehicle according to the current intersection category and the steering information of the first vehicle.
In this embodiment, after the current running position of the first vehicle is obtained, whether the first vehicle is currently running to the intersection position needs to be determined in advance, if the first vehicle is not running to the intersection position, whether the first vehicle is currently in a steering state needs to be determined, if the first vehicle is not in the steering state, the lane on which the first vehicle is currently running can be determined to be a straight lane, and further, the first light projection area can be determined to be a light projection area as shown in fig. 4, and at the moment, the first light projection area is matched with the shape of the lane on which the first vehicle is currently running; if the first vehicle is in the turning state, it is further required to confirm whether the turning state is one of a turning state, a turning state and a lane changing state, for example, if the turning state is the turning state, it may be determined that the road on which the first vehicle is currently running is a curved road, that is, the lane on which the first vehicle is currently running is a curved lane, and further it may be determined that the first light projection area is a light projection area as shown in fig. 7, and at this time, the first light projection area is also matched with the shape of the lane on which the first vehicle is currently running; for another example, if the steering state is determined to be the lane change state, the lane currently driven by the first vehicle may be defaulted to be a straight lane, and further, the first light projection area may be determined to be a light projection area as shown in fig. 9, that is, the same light projection area is additionally added to the light projection area as shown in fig. 4, and the light projection area is located on the lane after lane change.
If the first vehicle runs to the intersection position, whether the first vehicle is in a steering state at present or not is also required to be determined, if the first vehicle is not in the steering state at present, the type of the current intersection is required to be determined, namely, the current intersection is an intersection or an intersection, if the current intersection is an intersection, the first light projection area can be set as the light projection area shown in fig. 5, namely, the light projection area of the intersection is the whole intersection area as the first light projection area; if the current intersection is a fork intersection, the first light projection area can be set as a light projection area shown in fig. 6, and the area is based on the light projection area in front of the vehicle, and a light projection area of a right side traffic lane is additionally added; if the first vehicle is currently in the steering state, it may also be determined whether the current intersection is an intersection, and if so, the first light projection area may be directly set as the light projection area shown in fig. 8, that is, the light projection area in fig. 8 is obtained after horizontally moving to the steering position of the first vehicle on the basis of the light projection area in fig. 5.
And S130, adjusting the first light projection area according to the current running speed of the first vehicle to obtain a second light projection area of the first vehicle.
In this embodiment, after the first light projection area of the first vehicle is determined, the first light projection area is further adjusted according to the current running speed of the first vehicle, so as to improve the safe running of the vehicle at night. As shown in fig. 10, the leftmost light projection area in fig. 10 is longest, and the rightmost light projection area is shortest in the middle. Wherein the difference between the second light projection area and the first light projection area is only a difference in length. The second light projection area may be longer than the first light projection area, may be shorter than the first light projection area, or may be equal to the first light projection area. Meanwhile, in the process of adjusting the first light projection area by adopting the current running speed of the first vehicle, if the current speed is too high, the length of the first light projection area can be shortened to prompt the driver to run at too high speed, so that the driver is reminded of reducing the running speed of the vehicle, or the length of the first light projection area can be prolonged, the driver can be ensured to find a front obstacle in time, the driver can be ensured to be decelerated in time, and traffic accidents are avoided; if the current speed is slower, the length of the first light projection area can be shortened to prompt the driver to drive at too slow speed, and further prompt the driver to drive the vehicle at high speed, so that the vehicle is prevented from being driven at a tortoise speed, or the length of the first light projection area can be increased, the driver can be guaranteed to find the front obstacle in time, the driver can be guaranteed to be decelerated in time, and traffic accidents are avoided.
And S140, if an obstacle exists around the first vehicle, adjusting the second light projection area according to the position relation between the first vehicle and the obstacle, and obtaining a third light projection area of the first vehicle.
In this embodiment, the obstacle may be at least one of a pedestrian, an animal, a motor vehicle, and a non-motor vehicle around the vehicle, where the obstacle around the first vehicle may be detected by radar of the vehicle itself, or may be obtained by image acquisition by a camera configured by the vehicle itself, and the positional relationship is positional information of the obstacle around the vehicle in front of, on the left side of, on the right side of, or behind the vehicle. After determining that an obstacle exists around the first vehicle and acquiring the position relationship between the first vehicle and the obstacle, the second light projection area can be adjusted according to the position relationship to obtain a third light projection area of the first vehicle, and at the moment, the third light projection area of the first vehicle can not exist the obstacle or can not exist the obstacle, for example, if the obstacle is a vehicle right in front, namely, the second vehicle, the obstacle does not exist in the third light projection area, at the moment, light interference to the vehicle in front can be avoided, and if the obstacle is a pedestrian, an animal or a non-motor vehicle and is in a front deviated position, at the moment, the third light projection area can be expanded to the position where the obstacle exists, and then early warning can be carried out on a driver in advance, so that traffic accidents are avoided.
In other embodiments of the present 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 method further includes the steps of: and determining the position relation between the first vehicle and the second vehicle according to the light projection area of the second vehicle.
In this embodiment, the obstacle is a second vehicle that is traveling, the second vehicle is located in an adjacent lane of the current lane of the first vehicle, and the distance between the second vehicle and the first vehicle is relatively short, at this time, the current positional relationship between the second vehicle and the first vehicle may be identified from the acquired image by performing image acquisition on the light projection area of the second vehicle.
In other inventive embodiments, as shown in fig. 11, step S140 includes steps S141 and S142.
S141, if the position relation is that the second vehicle is positioned in front of the first vehicle and the second vehicle are positioned in the same traffic lane, acquiring a first interval between the first vehicle and the second vehicle;
and S142, adjusting the second light projection area according to the first interval distance to obtain a third light projection area of the first vehicle.
In this embodiment, the obstacle is a second vehicle running, the second vehicle is located right in front of the first vehicle, if the second light projection area is continuously illuminated, the second light projection area may be too long, so that the second vehicle is located in the second light projection area, and the driver in the second vehicle is disturbed, if the first vehicle is running at a relatively high speed, the following collision of the first vehicle is very easy to be caused if the second vehicle suddenly brakes, so that the second light projection area is not disturbed, and the driver of the first vehicle is reminded to reasonably control the vehicle speed, so that the first distance between the first vehicle and the second vehicle, that is, the following distance of the first vehicle, is required to be obtained, and then the length of the second light projection area is shortened through the first distance, so as to obtain the third light projection area of the first vehicle.
For example, as shown in fig. 12, when there is no vehicle right in front of the first vehicle, the second light projection area does not need to be adjusted, and the light projection area at the leftmost side in fig. 12 can be directly used; if there is a vehicle right in front of the first vehicle and the following distance of the first vehicle is far, the middle light projection area in fig. 12 may be used; if there is a vehicle right in front of the first vehicle and the following distance of the first vehicle is short, the rightmost light projection area in fig. 12 may be used.
In other inventive embodiments, as shown in fig. 13, step S140 includes steps S143, S144, S145, and S146.
S143, if the position relation is that the second vehicle is positioned in front of the first vehicle, and the current traffic lane of the first vehicle is adjacent to the traffic lane of the second vehicle, determining whether the first vehicle is in a lane change state;
s144, if the first vehicle is in the lane change state, determining whether the first vehicle changes lanes on the traffic lane of the second vehicle;
s145, if the first vehicle changes lanes on the traffic lanes of the second vehicle, determining a second interval between the first vehicle and the second vehicle after changing lanes;
and S146, adjusting the second light projection area according to the second interval distance to obtain a third light projection area of the first vehicle.
In this embodiment, in order to ensure that the vehicle can safely run at night, if the obstacle is a second vehicle running, the second vehicle is located in front of the first vehicle, and the traffic lane of the second vehicle is adjacent to the traffic 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 a lane-changing state, so that the adjusted light projection area can better provide safety service for the first vehicle. If the first vehicle changes lane on the traffic lane of the second vehicle, determining a second interval between the first vehicle and the second vehicle after lane change, namely a following distance between the first vehicle and the second vehicle after lane change, and then adjusting the second light projection area according to the second interval, namely adding a projection area of the first vehicle after lane change on the second light projection area, so as to finally obtain the light projection area shown in fig. 14; if the first vehicle is not changed in the lane of the second vehicle, the second projection area can be directly moved horizontally to the lane of the first vehicle after changing.
In other inventive embodiments, as shown in fig. 15, step S140 includes steps S1401, S1402, and S1403.
S1401, if the position relation is that the second vehicle is located in front of the first vehicle, and the current traffic lane of the first vehicle is adjacent to the traffic lane of the second vehicle, determining whether the first vehicle is in a overtaking state according to the current running speed of the first vehicle;
s1402, if the first vehicle is in a overtaking state, acquiring the number of the second vehicles in a traffic lane adjacent to the current traffic lane of the first vehicle;
s1403, adjusting the second light projection area according to the number of the second vehicles in the traffic lane adjacent to the current traffic lane of the first vehicle to obtain a third light projection area of the first vehicle.
In this embodiment, the obstacle is a second vehicle that is running, in order to more comprehensively ensure that the vehicle can safely run at night, when the second vehicle is located in front of the first vehicle or in front of the first vehicle, and the traffic lane of the second vehicle is adjacent to the traffic lane of the first vehicle, and the number of the second vehicles is at least one, when it is determined that the first vehicle is ready to overtake, in order to ensure that the first vehicle can safely overtake, after the number of the second vehicles in the traffic lane adjacent to the current traffic lane of the first vehicle is acquired in advance, the positional relationship between the first vehicle and each second vehicle is acquired, and then the second light projection area is adjusted according to the positional relationship between the first vehicle and each second vehicle, so as to obtain the light projection area, i.e. the third light projection area, which accords with the first vehicle to overtake safely.
For example, as shown in fig. 16, when two second vehicles are located in the left lane of the first vehicle, one of the second vehicles is located in front of the left lane, the other of the second vehicles runs side by side with the first vehicle, and one of the second vehicles located in front of the right lane of the first vehicle is located in front of the right lane of the first vehicle, at this time, the positional relationship between the first vehicle and each of the second vehicles can be obtained, and then the vehicle distance between the two second vehicles in the left lane is determined, and then based on the second light projection area, the light projection in the vehicle distance is formed, so as to form the light projection area shown in fig. 16. The application can further increase a light projection in the right lane according to the front-back distance between the first vehicle and the right vehicle, thereby further ensuring that the right obstacle is found in time.
In other inventive embodiments, as shown in fig. 17, step S140 includes steps S1404 and S1405.
S1404, if the position relation is that the current traffic lane of the first vehicle is adjacent to the traffic lane of the second vehicle, determining whether the first vehicle is currently running at an intersection;
s1405, if the first vehicle is currently running at the intersection, adjusting the second light projection area according to the light projection area of the second vehicle to obtain a third light projection area of the first vehicle.
In this embodiment, the obstacle is a second vehicle during driving, when the lane where the second vehicle is located is adjacent to the current lane of the first vehicle, and the distance between the first vehicle and the second vehicle is relatively short, in order to further improve safe driving at night, whether the first vehicle is currently driving at an intersection is further determined, and whether the intersection is an intersection where multiple lanes are converged into one lane, if so, in order to avoid that the second light projection area of the first vehicle overlaps with the light projection area of the second vehicle, so as to cause interference to the second vehicle, the light projection area of the second vehicle is required to be acquired, and then the light projection area of the second vehicle is adjusted according to the light projection area of the second vehicle, so as to obtain a light projection area that does not overlap with the light projection area of the second vehicle, that is, a third light projection area.
