Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
The embodiment of the present application provides a street lamp control method, which is executed by a route end, and as shown in fig. 1, provides a flow diagram of the street lamp control method in the embodiment of the present application, and the method at least includes the following steps S110 to S140:
and step S110, obtaining street lamp control information of the road end.
The street lamp control method in the embodiment of the present application may be executed by a Road end, and specifically may be executed by a Road Side controller in a Road Side Unit (RSU). The road side units can be deployed on two sides of a road, and can collect, analyze, monitor and the like information of vehicles, pedestrians and the like on a section of road near the road side units.
When street lamp control is performed, street lamp control information of a road end needs to be acquired first, the street lamp control information of the road end specifically includes information acquired by a sensor deployed on the road side and relevant configuration information of street lamp control, and the like, and the street lamp control information of the road end can be used as a basis for street lamp control in the embodiment of the application.
And step S120, acquiring the path planning information and the current positioning information sent by the vehicle end according to the street lamp control information of the road end.
Based on the road-end street lamp control information obtained in the previous step, path planning information and current positioning information reported by the vehicle-end are further required to be obtained, the path planning information includes a running track of the vehicle in a certain running area, and the current positioning information may include information such as a current specific position of the vehicle, for example, longitude and latitude coordinates, and a current running speed of the vehicle.
Step S130, determining a target vehicle corresponding to the road segment where the road end is located according to the path planning information, where the target vehicle includes at least one type of a vehicle about to enter the road segment where the road end is located, a vehicle already entering the road segment where the road end is located, and a vehicle leaving the road segment where the road end is located.
The route planning information reported by the vehicle end can provide a more fine adjustment basis for the street lamp control of the road end, and each road end is responsible for controlling and coordinating the street lamp illumination on the road section where the road end is located, so that the road end can determine which target vehicles are specifically and correspondingly located in the road section where the road end is located based on the route planning information.
In order to realize the fine control of the street lamp, the target vehicle can be divided into three types, namely, a vehicle which is about to enter a road section where a road end is located can be used as the target vehicle to realize the advanced coordination and timely adjustment of the street lamp illumination aiming at the vehicles, a vehicle which has already entered the road section where the road end is located is used as the target vehicle, and at least one type of vehicles which drive away from the road section where the road end is located is used as the target vehicle to mainly avoid the early or late adjustment of the street lamp illumination state and ensure the timely adjustment of the street lamp illumination state.
And step S140, controlling the street lamp illumination state of the road section where the road end is located according to the current positioning information of the target vehicle.
After the target vehicle is determined, the lighting state of the street lamp of the road section where the road end is located may be more finely adjusted according to the current positioning information of the target vehicle, where the adjustment may include, for example, adjustment of the lighting intensity of the street lamp and adjustment of the switching state of the street lamp.
According to the street lamp control method, the lighting state of the street lamp is more finely controlled by utilizing the path planning information reported by the vehicle end and the current positioning information, the resource waste of the street lamp in scenes such as idle roads is reduced, the collaborative control of the vehicle end and the road end on the lighting state of the street lamp is realized, the human intervention is reduced, and the control efficiency and the utilization rate of the street lamp are improved.
The street lamp control method is suitable for idle road scenes with relatively small traffic flow, the energy-saving control requirements and the adjusting space of the street lamp are larger under the scene, the light requirements of running vehicles at night under the condition of insufficient light can be met, and energy waste caused by continuous lighting is avoided.
The application is also suitable for road scenes with large traffic flow, the vehicles are continuously started when concentrated, the time periods of traffic flow reduction in the morning and the like are selectively started according to the situations, the light requirement of running vehicles is met, and energy waste caused by continuous light turning-on is avoided.
In some embodiments of the present application, the street lamp control information of the road end includes configuration information of sensor acquisition information and street lamp control, and the acquiring path planning information and current positioning information sent by the vehicle end according to the street lamp control information of the road end includes: determining whether to start a street lamp of a road section where the road end is located according to the sensor acquisition information and the configuration information of the street lamp control; and under the condition that the street lamp of the road section where the road end is located is determined to be started, acquiring path planning information and current positioning information which are sent by the vehicle end based on V2X communication.
The street lamp control information of the road end in the embodiment of the application specifically includes sensor acquisition information and street lamp control configuration information, and the sensor acquisition information may be ambient illumination intensity obtained through sensing of an illumination sensor deployed at the road end, or ambient illumination intensity identified by an image sensor deployed at the road end based on an image identification algorithm. Under the actual scene, the illumination intensity under different environment such as sunny day or cloudy day, rainy day all is different at daytime or night, and then also different to street lamp illumination state's demand, can detect the illumination intensity under the different environment through the sensor to provide preliminary judgement basis for street lamp control.
The configuration information of street lamp control mainly refers to information such as street lamp turn-on states and street lamp illumination intensities configured for street lamps in various road sections in different environments, for example, the street lamp turn-on state configured in sunny days is a turn-off state, and the street lamp illumination intensity configured in cloudy days is greater than that configured in sunny days. Of course, how to configure the street lamp control information specifically for the road end, those skilled in the art can flexibly set the street lamp control information according to actual requirements, and the configuration is not limited specifically here.
Because the street lamp control information of the road end is related to the environment of the road section, if the road is under the scene of clear day and the like, the street lamp of the road section can be obviously determined not to be started based on the street lamp control information of the road end, and under the condition, the practical necessity of further adjusting the lighting state of the street lamp by combining the V2X data of the vehicle end is avoided. Based on this, the embodiment of the application can determine whether the street lamp of the road section where the road end is located needs to be started or not, and then execute the subsequent operation under the condition of starting the street lamp of the road section where the road end is located.
In some embodiments of the present application, the path planning information includes a driving route of a vehicle, and the determining, according to the path planning information, a target vehicle corresponding to a road segment where the road end is located includes: determining whether the driving route of the vehicle passes through the road section where the road end is located; and taking the vehicle as a target vehicle under the condition that the running route of the vehicle passes through the road section where the road end is located.
The path planning information of the embodiment of the application may specifically include a driving route of a vehicle, the driving route of the vehicle may be generated in a vehicle-end human-computer interaction manner, the vehicle-end system and a user perform human-computer interaction to obtain start point and end point information input by the user, and then the path planning module automatically generates a planned driving route for the vehicle.
Since V2X communication transmits its V2X data to the outside in a broadcast manner, all road ends in the V2X communication range with the vehicle receive the V2X data of the vehicle, but the road segments where the road ends are located are not all road segments that the vehicle actually travels or passes through.
Based on this, the road end in the embodiment of the application may determine whether the driving route of the vehicle may pass through the road segment where the road end is located according to the received driving route information reported by the vehicle, and if the driving route of the vehicle may not pass through the road segment where the road end is located, it is obviously unnecessary to use the relevant information of the vehicle as the basis for controlling the street lamp. On the contrary, if the driving route of the vehicle passes through the road segment where the road end is located, which may include the situations of being passed, passing and just passing through the road segment, the vehicles may be used as the target vehicles of the road segment where the road end is located, and as the basis for the subsequent street lamp control.
The route planning information reported by the vehicle can provide a basis for fine control of the street lamp, and the problem of street lamp resource waste caused by the broadcasting characteristic of V2X communication in the existing scheme is solved.
In some embodiments of the present application, the controlling the street lamp lighting state of the road section where the road end is located according to the current location information of the target vehicle includes: determining the number of effective target vehicles corresponding to the road section where the road end is located according to the type of the target vehicle and the current positioning information of the target vehicle; and controlling the street lamp illumination state of the road section where the road end is located according to the current positioning information of the effective target vehicles and the number of the effective target vehicles.
The effective target vehicle in the embodiment of the application can be understood as a target vehicle which has a large influence on the street lamp control of the road section where the road end is located, or can be understood as a target vehicle which has a large influence on the illumination requirement of the target vehicle by the street lamp illumination state of the road section where the road end is located.
The types of the target vehicles may include, for example, three types, that is, a vehicle that is about to enter a road section where a road end is located, a vehicle that has already entered the road section where the road end is located, and a vehicle that travels away from the road section where the road end is located, and different types of target vehicles also have an influence on determination of valid target vehicles, so that the embodiment of the present application may determine, according to the type of the target vehicle and the current positioning information, whether the target vehicle is a valid target vehicle corresponding to the road section where the road end is located, and further obtain the number of valid target vehicles corresponding to the road section where the road end is located.
The number of the effective target vehicles on the road section where the road end is located indicates the number of the vehicles actually influenced by the street lamp lighting state of the road section, the more the number of the effective target vehicles is, the more the vehicles influenced by the street lamp lighting state are, that is, the more the vehicles on the road section have the street lamp lighting requirement, and vice versa, the fewer the vehicles are. Therefore, the street lamp lighting state of the road section where the road end is located can be finely adjusted according to the number of effective target vehicles and the current positioning information of the vehicles.
In some embodiments of the present application, the controlling the street lamp lighting state of the road segment where the road end is located according to the current location information of the valid target vehicles and the number of the valid target vehicles includes: determining the relative distribution position of the effective target vehicle and the road section where the road end is located according to the current positioning information of the effective target vehicle; determining the illumination intensity of the current road section according to the number of the effective target vehicles and the corresponding relation between the number of the vehicles and the illumination intensity of the road section; and determining the illumination intensity of each street lamp in the current road section according to the relative distribution position of the effective target vehicle and the road section where the road end is located and the illumination intensity of the current road section.
The street lamp control method is mainly applied to the idle road scene, so that the number of effective target vehicles corresponding to the road section is small in the same time, if all street lamps on the road section are turned on for illumination or provide strong illumination intensity, certain resource waste can still be caused, and therefore, on one hand, the illumination intensity required to be provided by the whole road section can be determined according to the number of the effective target vehicles corresponding to the current road section, on the other hand, the distribution condition of the effective target vehicles on the road section can be determined by combining the current positions of the effective target vehicles, and therefore the street lamps close to the effective target vehicles can be preferentially coordinated to provide illumination for the vehicles or enhance the illumination intensity of the vehicles.
That is, for the road end, the unified control of the street lamps of the road section where the street lamps are located may be to control the on-off state and the illumination intensity of each street lamp respectively, or to control the on-off state and the illumination intensity of a plurality of street lamps simultaneously.
As shown in fig. 2, a schematic view of the street lamp control effect in the embodiment of the present application is provided, and it can be seen from this that, the lighting control of the street lamp on the road section where the road side controller is located may be determined according to the driving direction and the distribution position of the vehicle (HV) on the road section, and according to the principle of proximity, the street lamp closest to the vehicle is preferentially called to provide lighting for the street lamp.
In addition, the embodiment of the application can establish the corresponding relation between the number of different effective target vehicles on the road section and the illumination intensity of the required street lamp in advance, for example, when the number of the effective target vehicles is 3, the illumination intensity of the corresponding street lamp is L1, when the number of the effective target vehicles is 5, the illumination intensity of the corresponding street lamp is L2, when the number of the effective target vehicles is 7, the illumination intensity of the corresponding street lamp is L3, and so on, the number of the effective target vehicles is more, and the illumination intensity of the street lamp is higher. The correspondence relationship may be a linear relationship or a nonlinear relationship.
Of course, in order to further simplify the processing, the determination may be made by setting a plurality of number sections, for example, when the number of effective target vehicles is within the first number section, the street lamp illumination intensity L1 is adopted, when the number of effective target vehicles is within the second number section, the street lamp illumination intensity L2 is adopted, when the number of effective target vehicles is within the third number section, the street lamp illumination intensity L3 is adopted, and so on.
It should be noted that, the above embodiments are only schematic descriptions, and how to determine the street lamp illumination intensities required by different effective target vehicle numbers specifically, a person skilled in the art may flexibly set the street lamp illumination intensities according to actual needs, and the embodiments are not limited in detail herein.
In some embodiments of the present application, the determining, according to the type of the target vehicle and the current positioning information of the target vehicle, the number of valid target vehicles corresponding to the road segment where the road end is located includes: if the target vehicle is a vehicle which enters the road section where the road end is located, directly taking the target vehicle as an effective target vehicle corresponding to the road section where the road end is located; and if the target vehicle is a vehicle about to enter the road section where the road end is located or a vehicle driving away from the road section where the road end is located, determining whether the target vehicle is an effective target vehicle corresponding to the road section where the road end is located according to the current positioning information of the target vehicle.
When the effective target vehicle is determined, different strategies can be adopted according to different types of the target vehicle, for example, if the target vehicle is a target vehicle which is driven into the road section at present, it is obvious that the street lamp illumination state of the road section affects the target vehicle, and therefore the target vehicle can be directly used as the effective target vehicle.
If the target vehicles are the target vehicles which are about to enter the road section where the road end is located or the target vehicles which are already driven away from the road section where the road end is located, the influence of the target vehicles on the street lamp illumination state of the road section is reduced compared with the target vehicles which are already driven into the road section because the target vehicles are not located on the road section, and whether the target vehicles need to be used as effective target vehicles of the road section or not can be determined by combining the current positioning information of the target vehicles.
In some embodiments of the present application, the determining, according to the current positioning information of the target vehicle, whether the target vehicle is a valid target vehicle corresponding to the road segment where the road end is located includes: determining the distance between the target vehicle and the road section where the road end is located according to the current position of the target vehicle and the position information of the road section where the road end is located; and determining whether the target vehicle is an effective target vehicle corresponding to the road section where the road end is located according to the distance between the target vehicle and the road section where the road end is located.
For the two types of target vehicles, namely the vehicle about to enter the road section where the road end is located and the vehicle driving away from the road section where the road end is located, when determining whether the target vehicles need to be used as effective target vehicles of the road section, the relative distance between the target vehicles and the road section can be calculated according to the current position reported by the target vehicles and the position information of the road section where the road end is located, the position information of each road section on the road can be regarded as known information, the absolute position of each road section on the world coordinate system is calibrated in the process of map construction, and the absolute position of each road section can specifically comprise the starting position and the ending position of the road section. For a vehicle that is about to enter the road segment where the end of the road is located, the relative distance between the vehicle and the start position of the road segment can be calculated, and for a vehicle that is leaving the road segment where the end of the road is located, the relative distance between the vehicle and the end position of the road segment can be calculated.
The closer the relative distance between the current position of the target vehicle and the road segment is, the more likely the target vehicle is influenced by the lighting state of the street lamp of the road segment, so that whether the target vehicle needs to be used as the valid target vehicle of the road segment can be preliminarily judged according to the relative distance, for example, if the relative distance is smaller than a preset distance threshold value, the target vehicle is used as the valid target vehicle, otherwise, the target vehicle does not need to be used as the valid target vehicle.
In some embodiments of the present application, the determining, according to the current positioning information of the target vehicle, whether the target vehicle is a valid target vehicle corresponding to the road segment where the end of the road is located further includes: determining the time for the target vehicle to reach/drive away from the road section where the road end is located according to the distance between the target vehicle and the road section where the road end is located and the current driving speed of the target vehicle; and determining whether the target vehicle is an effective target vehicle corresponding to the road section where the road end is located according to the time when the target vehicle arrives at or drives away from the road section where the road end is located.
Whether the target vehicle needs to be taken as an effective target vehicle or not is judged according to the distance between the target vehicle and the current road section, so that fine adjustment of street lamp control can be achieved to a certain extent, but special situations may exist, for example, for a vehicle about to enter the road section, the current distance between the target vehicle and the road section is relatively long, the target vehicle is judged to be not needed to be taken as the effective target vehicle directly through the distance, but the current running speed of the target vehicle is relatively high, the time for the vehicle to reach the road section is presumed to be relatively short based on the running speed, namely the vehicle can reach the road section very quickly, and then the street lamp lighting state of the road section is still influenced by the target vehicle with a high probability, so that in order to achieve early coordination of street lamp lighting, the problem of untimely lighting is avoided, and the target vehicle is more suitable to be taken as the effective target vehicle at this time.
On the contrary, if the current distance between the target vehicle and the road section is short, the target vehicle is directly judged to be required to be the effective target vehicle in a distance mode, but the current running speed of the target vehicle is low, the time for the target vehicle to reach the road section is estimated to be long based on the running speed, namely the target vehicle can reach the road section after a long period of time, then the influence of the street lamp illumination state of the road section on the target vehicle is considered to be low, and if the illumination of the street lamp is coordinated for the target vehicle in advance too early, a certain degree of resource waste is caused.
The comparison of the arrival time may also be implemented by a preset time threshold, for example, if the arrival time is less than the preset time threshold, the target vehicle may be regarded as an effective target vehicle, otherwise, the target vehicle does not need to be regarded as an effective target vehicle.
Of course, a constraint of a lower limit value may be added, and when the current distance between the target vehicle and the road segment is smaller than the lower limit value, it indicates that the distance between the target vehicle and the current road segment is already very small, and at this time, the current driving speed of the target vehicle may be directly used as the valid target vehicle without considering the size of the current driving speed of the target vehicle. Therefore, the running speed is adopted in the embodiment to further restrict the refined adjustment of the street lamp illumination, the timeliness of coordinating the street lamp illumination in advance can be ensured, the street lamp illumination is prevented from being adjusted too early or too late, and the utilization rate of the street lamp is improved.
Similarly, for a vehicle driving away from the current road segment, since the vehicle is gradually driven away, the influence of the street lamp illumination state of the current road segment on the target vehicle is also gradually changed, for example, if the current distance between the target vehicle which has been driven away and the road segment is far, because the vehicle has been driven away from the road segment, the vehicle can be judged to be no longer required to be an effective target vehicle by directly judging the distance in a distance-near manner without considering the problem of driving speed. If the current distance between the target vehicle that has traveled away and the road segment is still short, but the traveling speed of the target vehicle is high, and the target vehicle can rapidly travel away from the road segment for a long time in a short time, the target vehicle can no longer be taken as a valid target vehicle. And if the current distance between the target vehicle which is driven away and the road section is closer, but the driving speed of the target vehicle is small, the time for driving away from the road section is longer, and therefore the target vehicle can be continuously used as the effective target vehicle.
There is also a special case where the target vehicle is likely to enter a parking state when the traveling speed of the target vehicle is almost 0 for a certain period of time, and the target vehicle may not be regarded as a valid target vehicle even if the current distance between the target vehicle and the link is short.
It should be noted that the foregoing cases are merely exemplary illustrations made by the embodiments of the present application in conjunction with specific application scenarios, and how to determine an effective target vehicle specifically, and those skilled in the art may also adjust flexibly in conjunction with actual scenarios, which are not listed here.
