Description
Technical Field

[0002] With the improvement of people's living standards and the acceleration of the pace of society, the use of motor vehicles has become more and more common. At the same time, a large number of fast-moving motor vehicles on the road have posed a great threat to the safety of pedestrians. Pedestrians generally use dedicated crosswalks when crossing the road. A crosswalk refers to a walking area for pedestrians to cross the road marked by zebra crossings or other methods on the road, such as the zebra crossing passage at an intersection or the zebra crossing passage in the middle of the road. Some crosswalks are equipped with traffic lights, which are helpful for the safety of pedestrians. However, some crosswalks do not have traffic lights. Usually, the owners of motor vehicles may not actively slow down to avoid pedestrians when passing through the crosswalk due to reasons such as not seeing the crosswalk or not actively giving way. There are great safety hazards for pedestrians, and once an accident occurs, there is no better way to determine the responsibility for the accident.
[0003] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in the art need to solve at present. Summary of the invention

[0028] Preferably, the vehicle command system further includes:

[0050] The core of the present invention is to provide a vehicle command system for pedestrian crossings, which improves the safety of pedestrians and provides a basis for determining the responsibility for traffic accidents.
[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0052] Please refer to Figure 1 , Figure 1A schematic structural diagram of a pedestrian crossing prompt system provided by the present invention includes:
[0053] Traffic light 1;
[0054] Pedestrian detection device 2, used to detect whether there are pedestrians in a first preset area on the crosswalk;
[0055] The processor 3 connected to the traffic light 1 and the pedestrian detection device 2 respectively is used to control the yellow light or red light of the traffic light 1 to light up when there are pedestrians in the first preset area, so as to prompt the driver to pay attention to avoid pedestrians.
[0056] Specifically, the traffic light 1 can be of various types, such as a movable traffic light 1, which can be conveniently set on a pedestrian crossing without a traffic light. Of course, the traffic light 1 can also be fixed. No matter what type of traffic light 1 it is, it can include red, yellow and green traffic lights, and the embodiments of the present invention are not limited here.
[0057] Specifically, the pedestrian detection device 2 can detect whether there is a human body in the first preset area. If so, it can send a signal to the processor 3 so that the processor 3 can respond. Of course, if no human body is detected, it can also send a signal to the processor 3 so that the processor 3 can determine that the pedestrian detection device 2 is not faulty.
[0058] Among them, the first preset area can be independently set according to actual needs, and it can include all areas of the crosswalk, or it can include some areas around the crosswalk on the basis of including all areas of the crosswalk, etc. The embodiment of the present invention is not limited here.
[0059] Specifically, the processor 3 can control the yellow light or red light of the traffic light 1 to light up when receiving the signal that the pedestrian detection device 2 detects the presence of a human body in the first preset area. After seeing the yellow light, the driver can pay attention to slow down and avoid pedestrians. After seeing the red light, the driver can stop to let pedestrians pass first. In addition, the processor 3 in the embodiment of the present invention can also control the green light of the traffic light 1 to light up when it is determined that there is no human body in the first preset area. In this case, after seeing the green light, the driver can drive normally through the crosswalk, ensuring the safety of pedestrians.
[0060] Specifically, whether to control the yellow light or the red light to emit light can be independently set according to actual needs, and the embodiment of the present invention does not limit this.
[0061] The present invention provides a vehicle command system for a pedestrian crossing, comprising a traffic light; a pedestrian detection device, used to detect whether there are pedestrians in a first preset area on the pedestrian crossing; and a processor connected to the traffic light and the pedestrian detection device, used to control the yellow light or the red light of the traffic light to illuminate when there are pedestrians in the first preset area, so as to prompt the driver to pay attention to avoid pedestrians.
[0062] It can be seen that the processor can control the yellow or red light of the traffic light to light up when the pedestrian detection device detects the presence of pedestrians in the first preset area on the crosswalk. In this case, the driver will consciously avoid pedestrians after seeing the yellow or red light of the traffic light, thereby improving the safety of pedestrian traffic. After a traffic accident occurs, the responsibility can be determined by referring to the light color of the traffic light at the time of the traffic accident, which provides a basis for determining the responsibility of the accident.
[0063] Based on the above embodiments:
[0064] As a preferred embodiment, the pedestrian detection device 2 includes:
[0065] A first pedestrian detection sub-device 21 connected to the processor 3, for detecting whether there are pedestrians in a first preset sub-area on the crosswalk that does not overlap with the lane;
[0066] A second pedestrian detection sub-device 22 connected to the processor 3, for detecting whether there are pedestrians in a second preset sub-area of the crosswalk that coincides with the lane;
[0067] The processor 3 is specifically used to control the yellow light of the traffic light 1 to light up when there are pedestrians in the first preset sub-area, and to control the red light of the traffic light 1 to light up when there are pedestrians in the second preset sub-area, so as to prompt the driver to pay attention to avoid pedestrians;
[0068] Among them, the red light has a higher priority than the yellow light;
[0069] The first preset area includes a first preset sub-area and a second preset sub-area.
[0070] To better illustrate the embodiments of the present invention, please refer to Figure 2 , Figure 2 A scene simulation diagram of a pedestrian crossing provided by the present invention.
[0071] Specifically, in the embodiment of the present invention, the first preset area on the crosswalk can be divided into two parts, namely, the first preset sub-area on the crosswalk that does not overlap with the driving lane, and the second preset sub-area on the crosswalk that overlaps with the driving lane. When the pedestrian is in the first preset sub-area, the traffic light 1 can be controlled to emit a yellow light, and the driver will slow down at this time. When the pedestrian walks into the second preset sub-area, the traffic light 1 can be controlled to emit a red light, and the driver can change from a deceleration state to a parking state at this time, reserving time for the driver to react. If the traffic light 1 is controlled to emit a red light when the pedestrian is in the first preset sub-area, the driver may not be able to cope with the sudden change of the red light, thereby braking suddenly to cause danger, or accidentally running a red light and violating traffic regulations. This is very unfair and unreasonable for the driver. Therefore, in the embodiment of the present invention, the first preset area on the crosswalk is divided into two parts.
[0072] Specifically, the first pedestrian detection sub-device 21 can detect whether there is a human body in the first preset sub-area, and the second pedestrian detection sub-device 22 can detect whether there is a human body in the second preset sub-area. Both can send the detection results to the processor 3 in real time so that the processor 3 can control the light color of the traffic light 1.
[0073] Among them, considering the safety of pedestrians, the priority of the red light is set higher than that of the yellow light. In this case, if there are human bodies in the first preset sub-area and the second preset sub-area at the same time, the processor 3 will control the red light of the traffic light 1 to illuminate, thereby avoiding traffic accidents and further improving the safety of pedestrians.
[0074] Of course, the priority of the yellow light may also be set to be higher than the priority of the red light, which is not limited in the embodiment of the present invention.
[0075] In addition, the processor 3 can also control the red light of the traffic light 1 to illuminate only when the number of pedestrians in the second preset sub-area reaches a preset value, so as to avoid the motor vehicle being unable to drive normally due to frequent red light illumination. In this case, the second pedestrian detection sub-device 22 is required to detect the number of human bodies in the second preset sub-area and transmit the detection results to the processor 3.
[0076] As a preferred embodiment, the vehicle command system also includes:
[0077] A timing device 4 connected to the processor 3;
[0078] When there are pedestrians in the first preset sub-area, the processor 3 controls the yellow light of the traffic light 1 to emit light specifically as follows:
[0079] When there is a pedestrian in the first preset sub-area, the timing device 4 is controlled to start timing;
[0080] After the timing reaches a preset time, it is determined whether there are pedestrians in the first preset sub-area. If so, the yellow light of the traffic light 1 is controlled to light up.
[0081] Specifically, the timing device 4 may be of various types, for example, a counter inside the processor 3, etc., which is not limited in the embodiment of the present invention.
[0082] Specifically, considering that the pedestrians in the first preset sub-area are very likely not pedestrians crossing the road, for example, pedestrians walking on the sidewalk perpendicular to the direction of the crosswalk are also very likely to walk into the first preset sub-area. In this case, it is not necessary for the processor 3 to control the yellow light of the traffic light 1 to emit light. Therefore, the processor 3 in the embodiment of the present invention can control the timing device 4 to start timing when a human body is detected in the first preset sub-area, and judge whether there are still pedestrians in the first preset sub-area after the timing reaches the preset time. If there are pedestrians, it proves that the pedestrians in the first preset sub-area are very likely to be pedestrians waiting to cross the road. Therefore, the yellow light of the traffic light 1 can be controlled to emit light, which can avoid the phenomenon of controlling the traffic light 1 to emit light yellow due to detection of pedestrians who are not crossing the road, which is beneficial to the normal driving of motor vehicles.
[0083] The preset duration may be a variety of specific values, such as 3 seconds, etc., which is not limited in the embodiment of the present invention.
[0084] Of course, in addition to this, the yellow light can also be immediately controlled to emit light when there are pedestrians in the first preset sub-area, and the embodiment of the present invention is not limited here.
[0085] As a preferred embodiment, the vehicle command system also includes:
[0086] A light intensity sensor 5 connected to the processor 3, for detecting the light intensity of the surrounding environment;
[0087] A fill light 6 connected to the processor 3;
[0088] The processor 3 is further configured to control the fill light 6 to provide fill light to the first preset area when the light intensity is less than the first preset threshold.
[0089] Specifically, considering that the natural light intensity is weak at night, it brings considerable obstacles to the detection work of the pedestrian detection device 2, and the processor 3 cannot normally control the traffic light 1, which will also affect the safety of pedestrians. In the embodiment of the present invention, the light intensity sensor 5 can detect the illumination of the surrounding environment, and the processor 3 can control the fill light 6 to fill the first preset area when the illumination is less than the first preset threshold. In this case, the pedestrian detection device 2 can perform human body detection work as smoothly as in the case of sufficient natural light, which naturally improves the safety of pedestrians.
[0090] The light intensity sensor 5 may be of various types, which is not limited in the embodiment of the present invention.
[0091] The first preset threshold value may be independently set according to actual conditions, and is not limited in the embodiment of the present invention.
[0092] Specifically, the illumination intensity of the fill light 6 can be independently set according to demand and actual conditions, and the embodiment of the present invention does not limit this.
[0093] Of course, after the fill light is applied, if the light intensity of natural light increases, for example, when the sun rises, the light intensity of natural light plus the light intensity of the fill light 6 is naturally higher than the light intensity provided by the fill light 6 alone. When the light intensity sensor 5 detects that the light intensity of the surrounding environment is higher than the preset upper limit, the fill light 6 can be controlled to turn off, thereby saving electric energy.
[0094] The preset high limit value may also be set independently, which is not limited in the embodiment of the present invention.
[0095] As a preferred embodiment, the vehicle command system also includes:
[0096] A license plate recognition system 7 connected to the processor 3, for obtaining the license plate information of the vehicle;
[0097] A vehicle speed identification device 8 connected to the processor 3, for obtaining vehicle speed information;
[0098] The processor 3 is further configured to store the license plate information of a vehicle whose speed information is greater than a second preset threshold as speeding vehicle information when the yellow light of the traffic light 1 is on.
[0099] Specifically, considering that there is already a traffic light 1 in the pedestrian crossing area, the illegal motor vehicles can be recorded, which is conducive to punishment, and after a traffic accident occurs, it is also possible to directly check whether there is a violation record, further improving the convenience of accountability.
[0100] The license plate recognition system 7 may be of various types, for example, a camera with a built-in license plate recognition algorithm, etc., which is not limited in the embodiment of the present invention.
[0101] Specifically, the vehicle speed recognition device 8 may also be of various types, such as a camera with a built-in vehicle speed recognition algorithm, etc., which is not limited in the embodiment of the present invention.
[0102] The license plate information may be a vehicle license plate number, etc., which is not limited in this embodiment of the present invention.
[0103] Specifically, when the traffic light 1 is in the yellow light state, the driver cannot increase the speed of the motor vehicle to the second preset threshold. The speed recognition device can detect the speed information of each motor vehicle. When the processor 3 determines that the speed information of a motor vehicle is higher than the second preset threshold, the license plate information of the vehicle can be stored as speeding vehicle information. In this way, the violation of the motor vehicle can be documented, which provides assistance to the work of the traffic police and provides evidence for the accountability of traffic accidents.
[0104] As a preferred embodiment, the vehicle command system also includes:
[0105] Pedestrian triggering devices 9 are provided at both ends of the crosswalk and connected to the processor 3, and are used for pedestrians to generate control instructions;
[0106] The processor 3 is further configured to control the yellow light or the red light of the traffic light 1 to emit light when receiving a control instruction.
[0107] Specifically, the pedestrian trigger device 9 may be of various types, and its function is to generate a control instruction under the control of a pedestrian, for example, it may be a trigger button, etc., which is not limited in the embodiment of the present invention.
[0108] Specifically, after receiving the control instruction, the processor 3 can control the yellow light or red light of the traffic light 1 to light up. In this case, pedestrians can safely cross the crosswalk, providing another way to control the color of the traffic light 1. Even if the pedestrian detection device 2 fails, pedestrians can still actively control the color of the traffic light 1 through the pedestrian trigger device 9, further improving the safety of pedestrian passage.
[0109] Among them, the pedestrian trigger device 9 can be set at a safer position at both ends of the crosswalk, trying not to hinder the passage of vehicles, at the junction of a non-motorized vehicle lane and a motor vehicle lane, etc., and the embodiment of the present invention is not limited here.
[0110] Among them, it can be preset whether to control the yellow light or the red light to light up after receiving the control instruction, for example, to control the yellow light to light up after receiving the control instruction, etc., and the embodiment of the present invention is not limited here.
[0111] In addition, two pedestrian trigger devices 9 can be set at both ends of the crosswalk and distinguished by signs. Pedestrians on each side of the crosswalk can control the red light or the yellow light of the traffic light 1 through the two pedestrian trigger devices 9 respectively. Considering that there are a total of four pedestrian trigger devices 9 in this case, after the first pedestrian trigger device 9 is triggered, the lighting time of the yellow light or the red light can be maintained for a preset time period. Only after the preset time period has passed will it respond to the next control instruction to prevent program confusion.
[0112] As a preferred embodiment, the vehicle command system also includes:
[0113] A position identification device 10 connected to the processor 3, for obtaining position information of the vehicle;
[0114] The processor 3 is further configured to record the license plate information of vehicles whose position information is not located in the second preset area as red light running vehicle information when the traffic light 1 is red.
[0115] For a better description of the embodiments of the present invention, please refer to Figure 3 , Figure 3 Another vehicle command system for a pedestrian crossing is provided by the present invention.
[0116] Specifically, the position recognition device 10 may be of various types, such as a camera installed at a fixed position, which can obtain a pre-divided area where the vehicle is located in the image collected by itself and use this as position information, which is not limited in the embodiment of the present invention.
[0117] Among them, the second preset area can be of various types and can be set independently. For example, it can be an area of the motor vehicle lane bounded by the overlapping line of the crosswalk and the motor vehicle lane. Simply put, it is the rear of the stop line of the motor vehicle lane (this type of crosswalk generally may not have a stop line). The embodiment of the present invention is not limited here.
[0118] When the traffic light 1 turns red, the processor 3 records the license plate information of the vehicle whose position information is not within the second preset area as the red light running vehicle information, further providing a basis for determining the responsibility for the accident.
[0119] As a preferred embodiment, the road where the pedestrian crossing is located is a road with two-way lanes;
[0120] Then the traffic signal light 1 comprises a first traffic signal sub-light and a second traffic signal sub-light;
[0121] The processor 3 is specifically used for:
[0122] When there are pedestrians in the first preset area, the yellow light or the red light of the first traffic signal sub-light and the second traffic signal sub-light are synchronously controlled to illuminate, so as to simultaneously remind drivers on the two-way lanes to pay attention to avoid pedestrians.
[0123] Specifically, if the highway where the pedestrian crossing is located is a two-way lane highway, in this case, the traffic light 1 includes a first traffic signal sub-light and a second traffic signal sub-light, and the two traffic signal sub-lights can be used to respectively prompt drivers of motor vehicles in two directions. The processor 3 can synchronously control the first traffic signal sub-light and the second traffic signal sub-light during control, so that the drivers on the two-way lanes can be prompted to pay attention to avoid pedestrians at the same time, further improving the safety of pedestrian traffic.
[0124] As a preferred embodiment, the pedestrian detection device 2 includes:
[0125] A camera, used to obtain images within a preset area;
[0126] The processing modules connected to the camera and the processor 3 respectively are used to identify whether there is a pedestrian in the image through a human image recognition algorithm.
[0127] Specifically, the camera may be of various types, which is not limited in the embodiment of the present invention.
[0128] The processing module may identify whether there is a pedestrian in the image acquired by the camera through a human image recognition algorithm, and may also transmit the result of whether there is a pedestrian to the processor 3 .
[0129] The processing module may also be of various types, such as a single chip microcomputer, etc., which is not limited in the embodiment of the present invention.
[0130] As a preferred embodiment, the processor 3 is a roadside terminal in a V2X (vehicle to everything, vehicle-to-external information exchange) system;
[0131] The roadside terminal is also used to send the luminous color information of the traffic light 1 to the vehicle terminal in the V2X system;
[0132] The vehicle command system also includes a vehicle-mounted terminal connected to the roadside terminal.
[0133] Specifically, the vehicle-mounted terminal in the V2X system can send the luminous color information of the traffic light 1 to the vehicle-mounted terminal in the V2X system. In this case, after receiving the luminous color information from the roadside terminal, the vehicle-mounted terminal on the motor vehicle can know the luminous color of the traffic light 1 at the pedestrian crossing, so as to facilitate preparation in advance to avoid the occurrence of emergencies.
