[0016] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although some embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

[0017] In the description of the embodiments of the present disclosure, the term "including" and similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". Other explicit and implicit definitions may also be included below.

[0018] The term "in response to" means that the corresponding event occurs or the condition is satisfied. It will be understood that the timing of the execution of the subsequent action executed in response to the event or condition is not necessarily strongly related to the time when the event occurs or the condition is satisfied. In some cases, the subsequent action may be executed immediately when the event occurs or the condition is satisfied; in other cases, the subsequent action may be executed some time after the event occurs or the condition is satisfied.

[0019] The embodiments of the present disclosure may involve user data, data acquisition and / or use, etc. These aspects are subject to the corresponding laws, regulations and relevant provisions. In the embodiments of the present disclosure, all data collection, acquisition, processing, processing, forwarding, use, etc. are carried out on the premise that the user knows and confirms. Accordingly, when implementing each embodiment of the present disclosure, the type, scope of use, usage scenario, etc. of the data or information that may be involved should be informed to the user and the user's authorization should be obtained in an appropriate manner in accordance with the relevant laws and regulations. The specific notification and / or authorization method can vary according to the actual situation and application scenario, and the scope of the present disclosure is not limited in this respect.

[0020] The solutions described in this specification and in the examples, if they involve the processing of personal information, will be processed on the premise of having a legal basis (such as obtaining the consent of the subject of personal information, or being necessary for the performance of a contract, etc.), and will only be processed within the scope of regulations or agreements. If a user refuses to process personal information other than the necessary information for basic functions, it will not affect the user's use of basic functions.

[0021] As discussed above, the detection and recognition of traffic lights are of great significance to the realization of autonomous driving. Traffic lights can also be referred to as traffic lights for short, and the two are used interchangeably in this article. The autonomous driving system can control the traffic status of the vehicle based on the results of the detection and recognition of traffic lights. Traditionally, the camera installed on the vehicle (also referred to as a mobile carrier) is mainly used to capture the image in front of the vehicle in real time, and the traffic lights are detected and recognized in real time based on the captured image. There are problems such as high cost and difficult maintenance in installing cameras, which will affect the real-time performance, robustness and scalability of the autonomous driving system. In addition, in the case of dense traffic lights, dirty camera lenses or poor light at night, the solution of detecting and identifying traffic lights based on the images captured by the camera may not provide accurate results. Inaccurate detection and recognition results will affect the control of the traffic status of the vehicle by the autonomous driving system, thereby affecting driving safety.

[0022] Embodiments of the present disclosure propose a scheme for controlling a vehicle based on a broadcast signal. According to various embodiments of the present disclosure, the status data of a traffic light is received at the vehicle via a broadcast signal. Based on the status data of the traffic light and the status data of the vehicle, it is determined whether the traffic light is a valid traffic light for controlling the vehicle. Here, the valid traffic light may represent a traffic light for controlling the next intersection that the vehicle is about to pass. The vehicle is controlled based on the status data of the valid traffic light.

[0023] In this way, based on the broadcast signal containing the state data of the traffic light, the traffic light can be detected and identified conveniently and quickly, which can avoid the identification error caused by environmental reasons and help improve the accuracy of the detection and identification results. Furthermore, the vehicle can be controlled based on the detection and identification results of the traffic light, which helps to ensure traffic safety.

[0024] Figure 1AA schematic diagram of an example environment 100A in which an embodiment of the present disclosure can be implemented is shown. As shown in FIG. 1 , the environment 100A may include at least one vehicle 101 (for example, it may include vehicle 101-1, vehicle 101-2, and vehicle 101-3, collectively referred to as vehicle 101), a traffic light 102, a road side unit (RSU) 103, and a stop line 104. The road side unit 103 is a device installed near the road where the vehicle 101 is located, and is usually installed at an intersection. For example, it can be installed on the traffic light 102 or in an area within a certain distance near the traffic light 102. The road side unit 103 can be used to send a broadcast signal containing status data of the traffic light 102, and such a broadcast signal can also be referred to as a road side signal. The broadcast mode of the road side unit 103 can be, for example, PC5 (a device-to-device broadcast mode). Both the road side unit 103 and the electronic device 110 may include a device-to-device direct communication interface. Neighboring devices can send and receive broadcast signals through direct links for data transmission within a short range, without the need for forwarding through a central node (such as a base station) or information transmission through traditional cellular links.

[0025] The stop line 104 may indicate the location of the intersection. When the traffic light 102 indicates that passage is not allowed (e.g., when the traffic light 102 is red), the vehicle 101 may not cross the stop line 104, and the vehicle 101 must be located behind the stop line 104 (i.e., away from the intersection). In some embodiments, the distance between the vehicle 101 and the stop line 104 may be regarded as the intersection distance between the vehicle 101 and the intersection.

[0026] An electronic device 110 is installed on the vehicle 101. For example, the electronic device 110-1 is installed on the vehicle 101-1, the electronic device 110-2 is installed on the vehicle 101-2, and the electronic device 110-3 is installed on the vehicle 101-3. The electronic device 110 may include any computing system with computing capabilities, such as various computing devices / systems, terminal devices, server devices, etc. The electronic device 110 is an electronic device associated with the vehicle 101. In some embodiments, the electronic device 110 may be directly included in the vehicle 101, for example, it may be a device fixedly installed in the vehicle 101. Alternatively or additionally, in some embodiments, the electronic device 110 may also exist independently of the vehicle 101. In some embodiments, the electronic device 110 may, for example, be installed at any appropriate location of the vehicle 101.

[0027] In some embodiments, a detection device 120 is installed in the electronic device 110. The detection device 120 includes a processing unit 121, a positioning unit 122, a network communication unit 123, a broadcast receiving unit 124, a speed measuring unit 125, an execution unit 126 and a bus 127.

[0028] The positioning unit 122 can be used to provide real-time latitude and longitude information and direction information of the vehicle 101. In some embodiments, in order to improve the accuracy of subsequent detection and identification of traffic lights, the positioning unit 122 can use a differential positioning (RTK) algorithm. The positioning unit 122 that supports the RTK algorithm can provide more accurate location information. The network communication unit 123 can be used to communicate with the cloud server over the Internet. The broadcast receiving unit 124 can be used to receive roadside signals in real time. It can be understood that the broadcast signal received by the broadcast receiving unit 124 includes a roadside signal sent by at least one roadside unit 103, or may also include a broadcast signal sent by other vehicles. The speed measurement unit 125 can be used to detect the current driving speed of the vehicle 101.

[0029] The execution unit 126 can be used to control the electronic device 110 to perform related actions based on the recognition result of the traffic light 102. For example, when the traffic light 102 indicates that passage is not allowed and the driving speed of the vehicle 101 itself is non-zero, the electronic device 110 is controlled to issue a voice warning reminder or instruct the vehicle 101 to slow down or brake immediately. Alternatively and / or additionally, in the automatic driving mode, the execution unit 126 can directly control the vehicle 101 to slow down or stop.

[0030] The processing unit 121 is used to process and judge the data between the positioning unit 122, the network communication unit 123, the broadcast receiving unit 124, the speed measuring unit 125, etc. and control the execution unit 126. The processing unit 121, the positioning unit 122, the network communication unit 123, the broadcast receiving unit 124, the speed measuring unit 125 and the execution unit 126 can be controlled and exchange information data through the bus 127. The bus 127 includes but is not limited to a serial port, SPI, CAN, etc.

[0031] In the context of the present disclosure, the following can be used: Figure 1A The electronic device 110 at the vehicle end is shown to control the process of the vehicle based on the broadcast signal. Alternatively and / or additionally, the above process can be performed at a cloud location. Figure 1B Schematic diagram of an example detection system 100B of some embodiments of the present disclosure is shown. Figure 1B As shown, the detection system 100B includes a detection platform 130 (e.g., located in the cloud). The traffic server 140 can transmit a signal to the roadside unit 150, thereby informing the roadside unit 150 of the status of the corresponding traffic light. These roadside units can include, for example, Figure 1A The roadside unit 103 shown. The detection platform 130 can obtain relevant information of the traffic light (such as the latitude and longitude information, direction information, and status information of the traffic light), and then identify whether the vehicle has run a red light and potential red light running and other dangerous behaviors, and provide corresponding processing results.

[0032] For the convenience of description, the following describes the process of controlling the vehicle based on the broadcast signal by taking the electronic device 110 at the vehicle end as an example. It should be understood that the structure and function of the environment 100 are described only for exemplary purposes and do not imply any limitation on the scope of the present disclosure. Some example embodiments of the present disclosure will continue to be described with reference to the accompanying drawings.

[0033] Figure 2 A flow chart of a process 200 for controlling a vehicle based on a broadcast signal according to some embodiments of the present disclosure is shown. The process 200 may be implemented at the electronic device 110. For ease of discussion, the process 200 will be described with reference to the environment 100 of FIG. 1 .

[0034] In block 210 , the electronic device 110 receives state data of a traffic light at a vehicle via a broadcast signal, the traffic light being used to control a traffic state of a vehicle passing through a target intersection.

[0035] For example, the electronic device 110 can receive a broadcast signal within a certain range around the vehicle in real time through the broadcast receiving unit 124. This broadcast signal can be a broadcast signal sent by a roadside unit (such as the roadside unit 103) on the road where the vehicle is located. In some embodiments, the electronic device 110 can also include a broadcast unit (not shown in FIG. 1). The electronic device 110 can broadcast the status data of the traffic light to other vehicles through the broadcast unit. That is, the electronic device 110 can forward the broadcast signal including the status data of the traffic light through the RSU sending unit.

[0036] Figure 3 Schematic diagram 300 of receiving a broadcast signal according to some embodiments of the present disclosure is shown. Figure 3 As shown in the figure, V1, V2, and V3 represent three different vehicles respectively, and RSU represents the roadside unit on the road where the vehicle is located. If the vehicle is currently located in the AB section, then the RSU in the figure can represent the roadside unit installed at the end of the AB section, that is, at the intersection corresponding to position B. A section is a traffic route between two nodes on a traffic network, which can usually be understood as a section of the road between two intersections. Circle 301 in the figure represents the area that can receive the broadcast signal sent by the RSU. For vehicle V1, if the location of vehicle V1 overlaps with the area included in circle 301, vehicle V1 can receive the broadcast signal sent by the RSU.

[0037] After vehicle V1 parses the broadcast signal it receives to obtain the status data of the traffic light, it can broadcast a broadcast signal containing the status data of the traffic light to other vehicles. In order to distinguish the broadcast signal received by vehicle V1 from the broadcast signal broadcasted externally by the vehicle, the broadcast signal received by vehicle V1 may be referred to as a broadcast signal, and the broadcast signal broadcasted by vehicle V1 may be referred to as broadcast data in this article. The broadcast data broadcasted externally by vehicle V1 may include the same data as the broadcast signal received by vehicle V1, or may include different data (for example, it may be broadcast data generated by the electronic device of vehicle V1 processing the broadcast signal).

[0038] Vehicles within a certain range of vehicle V1 and outside the area where circle 301 is located (that is, vehicles that cannot receive the broadcast signal sent by the RSU) can receive the broadcast data broadcast by vehicle V1. For example, vehicle V2 can receive the broadcast data broadcast by vehicle V1. In some embodiments, a vehicle that receives the broadcast data broadcast by vehicle V1 can further broadcast the broadcast data so that other vehicles can receive the broadcast data. For example, vehicle V2 can secondary forward the received broadcast data broadcast by vehicle V1 so that other vehicles can receive the broadcast data broadcast by vehicle V2. Exemplarily, for vehicle V3, the broadcast data it receives can be the broadcast data directly broadcast by vehicle V1, or it can be the broadcast data secondary forwarded by vehicle V2.

[0039] The state data of the traffic light may include, for example, the direction (i.e., orientation), position, display state, type of the traffic light, etc. The electronic device 110 may parse the state data of the traffic light to obtain information included in the state data. The type of the traffic light may include, for example, a traffic light for controlling pedestrians, a traffic light for controlling non-motorized vehicles, a traffic light for controlling motorized vehicles, etc.

[0040] The display state may indicate, for example, the color of the effective traffic light. For example, taking the effective traffic light as a red, yellow, and green traffic light, the display state may include red, yellow, and green. Different display states may indicate whether the intersection where the effective traffic light is located allows vehicles to pass. For example, when the display state is red or yellow, it indicates that passage is not allowed. When the display state is green, it indicates that passage is allowed.

[0041] At block 220 , the electronic device 110 determines whether the traffic light is a valid traffic light for controlling the vehicle based on the state data of the traffic light and the state data of the vehicle.

[0042] If the broadcast signal received by the electronic device 110 includes only the status data of one traffic light, the electronic device 110 can determine whether the traffic light is a valid traffic light for controlling the vehicle based on the status data of the traffic light and the status data of the vehicle. The status data of the vehicle may include, for example, the direction of the vehicle (also referred to as the orientation of the vehicle), the direction of movement of the vehicle (also referred to as the driving direction of the vehicle), the driving speed of the vehicle, etc. Since there are often multiple traffic lights at road intersections (especially crossroads), and these traffic lights are often used to control vehicles with different directions of movement, the broadcast signal received by the electronic device 110 may also include the status data of multiple traffic lights, and the status data of these traffic lights include the status data of different traffic lights located at the same intersection but indicating vehicles in different directions.

[0043] In the case where the received broadcast signal may include status data of multiple traffic lights, if the road intersection includes only one roadside unit, the broadcast signal received by the electronic device 110 is the broadcast signal of the roadside unit. The electronic device 110 parses the broadcast signal to obtain the status data of multiple traffic lights, and filters the status data of multiple traffic lights included in the broadcast signal based on the status data of the traffic lights and the status data of the vehicle. The electronic device 110 can identify the status data of valid traffic lights from the status data of the traffic lights, that is, determine whether each of the multiple traffic lights corresponding to the status data of the traffic lights is a valid traffic light.

[0044] If the road intersection includes multiple roadside units, the broadcast signal of each of the multiple roadside units may include the status data of a specified traffic light. The broadcast signal acquired by the electronic device 110 may be multiple broadcast signals sent by multiple roadside units. The electronic device 110 may filter the multiple broadcast signals based on the status data of the traffic light and the status data of the vehicle respectively included in these broadcast signals, so as to identify the valid broadcast signals containing the status data of the valid traffic light from these broadcast signals, that is, it can identify whether the traffic lights corresponding to these broadcast signals are respectively valid traffic lights.

[0045] For the convenience of description, the following description will be given by taking the broadcast signal received by the electronic device 110 as an example, in which the broadcast signal includes a broadcast signal broadcast by at least one roadside unit. Here, the broadcast signal broadcast by each roadside unit in the at least one roadside unit includes the status data of a traffic light (that is, one broadcast signal corresponds to the status data of one traffic light).

[0046] For different traffic lights, the electronic device 110 can determine whether it is a valid traffic light for the vehicle based on the state data of the traffic light and the state data of the vehicle. Specifically, if the direction and position of the traffic light parsed from the state data of the traffic light and the movement direction of the vehicle meet a predetermined condition, the electronic device 110 can identify the traffic light as a valid traffic light.

[0047] The predetermined condition may, for example, include that the direction of the traffic light and the direction of movement of the vehicle satisfy a predetermined angle condition. Exemplarily, the predetermined angle condition may, for example, indicate a threshold angle, and when the angle between the direction of the traffic light and the direction of movement of the vehicle is less than the threshold angle, the electronic device 110 may identify the traffic light as a valid traffic light. The predetermined angle condition may, for example, also indicate a predetermined angle range. When the angle between the direction of the traffic light and the direction of movement of the vehicle is within a predetermined angle range (e.g., [160°, 200°] or other ranges), the electronic device 110 may identify the traffic light as a valid traffic light. In this way, the accuracy of determining the traffic light may be improved, thereby improving the efficiency of post-processing.

[0048] Figure 4 Schematic diagram 400 of effectively determining a traffic light according to some embodiments of the present disclosure is shown. Figure 4 As shown, the direction of the traffic light 102 is the direction indicated by arrow 401, and the moving direction of the vehicle 101 is the direction indicated by arrow 402. The electronic device 110 can, for example, determine whether the traffic light 102 can be identified as a valid traffic light based on a comparison of the angle between the direction indicated by arrow 401 and the direction indicated by arrow 402 with a threshold angle and / or a predetermined angle range. Exemplarily, if the predetermined angle range is [160°, 200°], then when the angle between the direction indicated by arrow 401 and the direction indicated by arrow 402 is within this predetermined angle range, the electronic device 110 can identify the traffic light 102 as a valid traffic light.

[0049] In some embodiments, the electronic device 110 may determine a straight line that matches the direction of the traffic light 102 and the direction of movement of the vehicle 101, and determine the positional relationship between the two straight lines. Figure 4 As shown, dotted line 403 is a straight line in the direction indicated by arrow 401, and dotted line 404 is a straight line in the direction indicated by arrow 402. If dotted line 401 is parallel to dotted line 404 (ie, the angle is 180°), electronic device 110 can identify traffic light 102 as a valid traffic light.

[0050] Since there are multiple roads that are close to each other, in this case, there is a possibility that the direction of a certain traffic light satisfies the above-mentioned predetermined angle condition, but the traffic light is used to control vehicles on other roads. Therefore, in some embodiments, the predetermined condition may also include, for example, that the vertical distance between the position of the traffic light and the straight line where the direction of movement of the vehicle is located satisfies the predetermined distance condition. The predetermined distance condition may, for example, indicate a threshold distance. The electronic device 110 may, for example, determine the vertical distance between the position of the traffic light and the straight line where the direction of movement of the vehicle is located. The electronic device 110 may then compare the vertical distance with the threshold distance indicated by the predetermined distance condition.

[0051] When the vertical distance is less than the threshold distance, the electronic device 110 may determine that the traffic light is a traffic light on the road where the vehicle is located, and further identify the traffic light as a valid traffic light. Figure 4 , the electronic device 110 may determine a vertical distance S between the location of the traffic light 102 and the dashed line 404. If the vertical distance S is less than a threshold distance, the electronic device 110 identifies the traffic light 102 as a valid traffic light.

[0052] In some embodiments, after the electronic device 110 determines the valid traffic lights, it can generate broadcast data based on the status data of the valid traffic lights and broadcast it to other vehicles. That is, the broadcast data broadcast by the electronic device 110 is broadcast data that only includes the status data of the valid traffic lights rather than the status data of all the traffic lights obtained by parsing. In some embodiments, the electronic device 110 can also directly generate broadcast data based on the status data of all the traffic lights obtained by parsing, and the electronic device 110 can perform special processing on the status data of the valid traffic lights so that other electronic devices 110 that receive the broadcast data can determine which of them are the status data of the valid traffic lights.

[0053] Since the valid traffic lights for different vehicles may be different, in order to facilitate the electronic devices of other vehicles (e.g., the second vehicle) receiving the broadcast data to determine whether the status data of the valid traffic lights included in the broadcast data is the status data of the valid traffic lights used to control their own vehicles, in some embodiments, for a certain traffic light, if the traffic light is determined to be a valid traffic light (i.e., the status data of the traffic light is determined to be the status data of the valid traffic light), the electronic device 110 may obtain the segment identifier of the segment where the vehicle (also referred to as the first vehicle) is located. The segment identifier may, for example, indicate the segment name and / or ID (e.g., AB segment), the segment location, the coded location of the segment, etc. The electronic device 110 may determine the specific segment indicated by the segment identifier based on the segment identifier.

[0054] The electronic device 110 can generate broadcast data based on the road segment identifier and the status data of the valid traffic light, and broadcast the status data of the traffic light and the road segment identifier to other vehicles other than the vehicle via the broadcast data. That is, the electronic device 110 of the first vehicle can broadcast the status data of the traffic light and the road segment identifier to the second vehicle via the broadcast data.

[0055] For the second vehicle that receives the broadcast data, if it is determined that the broadcast signal includes a road segment identifier, the electronic device of the second vehicle can obtain the current road segment identifier of the current road segment where the second vehicle is located, and when it is determined that the road segment identifier matches the current road segment identifier, the electronic device can subsequently control the second vehicle based on the status data of the traffic light. In this case, the electronic device of the second vehicle can directly determine whether the received broadcast signal is a broadcast signal including the status data of a valid traffic light for the second vehicle based on the matching result of the current road segment identifier of the second vehicle and the road segment identifier included in the received broadcast signal. In this way, the efficiency of determining the valid traffic light can be improved, thereby improving the efficiency of the electronic device in subsequently controlling the vehicle based on the status data of the valid traffic light.

[0056] In some embodiments, the broadcast data broadcast by the first vehicle may not include the road segment identifier. The electronic device 110 receiving the broadcast data may determine whether the traffic light included in the broadcast data is a valid verification light for its corresponding vehicle based on the above-mentioned method of determining whether the traffic light is a valid traffic light.

[0057] In some embodiments, the broadcast data sent by the vehicle may include a road segment identifier, alternatively and / or additionally, the broadcast data sent by the vehicle may not include a road segment identifier. Further, the broadcast data sent by the roadside unit may include a road segment identifier, alternatively and / or additionally, the broadcast data sent by the roadside unit may not include a road segment identifier. At this time, after receiving the broadcast data, it may be first determined whether the broadcast data includes a road segment identifier.

[0058] If the broadcast data includes a road segment identifier, the valid traffic light can be determined based on whether the road segment identifier in the broadcast data is the same as the road segment identifier of the road segment where the vehicle is located. If the broadcast data does not include a road segment identifier, it can be determined whether the traffic light is a valid traffic light for controlling the vehicle based on the state data of the traffic light and the state data of the vehicle. Alternatively and / or additionally, valid traffic lights determined based on different methods can be cross-validated to further improve the accuracy of determining the valid traffic light.

[0059] At block 230 , if it is determined that the traffic light is a valid traffic light, the electronic device 110 controls the vehicle based on the status data of the traffic light.

[0060] In some embodiments, before controlling the traffic state of a vehicle passing through a target intersection based on the status data of a valid traffic light, the electronic device 110 needs to determine whether the type of the valid traffic light matches the type of the vehicle. It is understood that only when the types match can the valid traffic light be used to control the traffic state of the vehicle. Specifically, the electronic device 110 can, for example, parse the type of the valid traffic light from the status data of the valid traffic light, and control the vehicle based on the status data of the valid traffic light when it is determined that the type of the valid traffic light matches the type of the vehicle. For example, if the type of the valid traffic light is a traffic light for controlling a motor vehicle and the type of the vehicle is a motor vehicle, the electronic device 110 determines that the type of the valid traffic light matches the type of the vehicle. The electronic device 110 can then control the vehicle based on the status data of the valid traffic light.

[0061] In addition to the display state, in some embodiments, the electronic device 110 can also control the vehicle in conjunction with the intersection distance between the vehicle and the target intersection. As mentioned above, this intersection distance refers to the distance between the vehicle and the stop line of the target intersection. Specifically, the electronic device 110 can parse the display state of the effective traffic light from the state data of the effective traffic light, and control the vehicle based on the display state and the intersection distance between the vehicle and the target intersection.

[0062] In some embodiments, if it is determined that the display state indicates that passage is allowed, the electronic device 110 can determine the travel distance of the vehicle based on the duration of the display state and the speed of the vehicle. It can be understood that the duration of the display state here corresponds to the current display state of the traffic light. In some embodiments, the traffic database can also include the duration of the display state of the traffic light. In this case, the duration of this display state can be obtained by the electronic device 110 from the traffic database based on the effective traffic light in real time. In some embodiments, the duration of the display state can also be obtained by the electronic device 110 using a machine learning model to predict based on historical data.

[0063] The duration of the display state may refer to, for example, the remaining time for an effective traffic light to switch from the current display state to another display state. For example, for a red, yellow, and green traffic light, if the current display state is red, the display state of the traffic light will switch to yellow after 20 seconds, and the display state duration of the traffic light may be, for example, 20 seconds.

[0064] The electronic device 110 may use the speed-distance formula to determine the distance traveled by the vehicle during the duration of the display state based on the duration of the display state and the speed of the vehicle. Exemplarily, assuming that the vehicle is traveling at a constant speed, the electronic device 110 may, for example, determine the distance traveled by the vehicle as the product of the remaining time of the display state and the speed of the vehicle. Assuming that the vehicle is traveling at a non-uniform speed (e.g., traveling at a uniformly variable speed), the electronic device 110 may also obtain the acceleration of the vehicle and determine the distance traveled by the vehicle based on the acceleration of the vehicle, the speed of the vehicle, and the duration of the display state.

[0065] In some embodiments, when the intersection distance is less than or equal to zero, the electronic device 110 can determine that the stop line is located behind the vehicle's driving direction or coincides with the vehicle's position, and the vehicle is passing through the intersection. The electronic device 110 can then control the vehicle based on the display state of the effective traffic lights and the intersection distance between the vehicle and the target intersection. In some embodiments, when the intersection distance is greater than zero, the electronic device 110 can determine that the stop line is located in front of the vehicle's driving direction, and the vehicle has not passed the intersection. The electronic device 110 can then control the vehicle based on the display state of the effective traffic lights, the vehicle's driving distance, and the intersection distance between the vehicle and the target intersection.

[0066] Some examples of intersection distance being greater than zero are described below. In some embodiments, the electronic device 110 determines the travel distance of the vehicle based on the duration of the display state and the speed of the vehicle in response to determining that the display state indicates that passage is allowed and the intersection distance is greater than zero. The electronic device 110 can then calculate the difference between the travel distance and the intersection distance, and in response to determining that the difference between the travel distance and the intersection distance meets the safety distance condition, allow the vehicle to pass through the intersection.

[0067] Exemplarily, when the display state of the valid traffic light is green, it indicates that the vehicle is allowed to pass the target intersection. Since the electronic device 110 can only allow the vehicle to pass the intersection when the driving distance is greater than the intersection distance, the safety distance condition here can be, for example, that the difference obtained by subtracting the intersection distance from the driving distance is greater than 0. That is, the electronic device 110 instructs the vehicle to pass the target intersection in response to the difference obtained by subtracting the intersection distance from the driving distance being greater than 0. In response to determining that the difference between the driving distance and the intersection distance does not meet the safety distance condition, the electronic device 110 prompts the vehicle to slow down.

[0068] For example, when the driving distance is less than or equal to the intersection distance (i.e., the difference obtained by subtracting the intersection distance from the driving distance is less than or equal to 0), the vehicle cannot pass through the intersection when the display state indicates that passage is allowed (i.e., a green light). The electronic device 110 can present a prompt message to the passengers inside the vehicle (e.g., the driver) to prompt the vehicle to slow down, thereby avoiding violations when the display state switches to not allowing passage (e.g., a red light). The electronic device 110 can present the prompt information by, for example, playing audio, vibrating, playing video, presenting text, and the like.

[0069] In some embodiments, the electronic device 110 determines the driving distance of the vehicle based on the duration of the display state and the speed of the vehicle in response to determining that the display state indicates that passage is prohibited and the intersection distance is greater than zero. The electronic device 110 further prompts the vehicle to slow down in response to determining that the difference between the driving distance and the intersection distance does not meet the safety distance condition.

[0070] Exemplarily, when the display state of the effective traffic light is red or yellow, it can indicate, for example, that the vehicle is prohibited from passing the target intersection. If the safety distance condition is that the difference obtained by subtracting the intersection distance from the driving distance is greater than 0, then when the safety distance condition is met, the electronic device 110 can determine that if the vehicle continues to travel in the current state, the vehicle will exceed the stop line during the duration of the display state, and even pass the intersection illegally. The electronic device 110 then prompts the vehicle to slow down. Similarly, the electronic device 110 can present a prompt message to the personnel inside the vehicle (such as the driver) to prompt the vehicle to slow down, thereby avoiding violations when the display state is that passage is not allowed (such as a red light).

[0071] Some examples of intersection distances less than or equal to zero are described below. In some embodiments, the electronic device 110 determines that a vehicle has violated the rules by passing through an intersection in response to determining that the display state of a valid traffic light indicates that passage is prohibited and the intersection distance is less than or equal to zero. The electronic device 110 can prompt that the vehicle has violated the rules by passing through an intersection. Similarly, the electronic device 110 can prompt that the vehicle has violated the rules by presenting a prompt message. The electronic device 110 can present the prompt information, for example, by playing audio, vibrating, playing video, presenting text, and the like.

[0072] It is understandable that, when it is determined that the display state of the valid traffic light indicates that passage is allowed and the intersection distance is less than or equal to zero, the electronic device 110 can determine that the vehicle passes through the intersection normally. The electronic device 110 does not need to present a prompt message.

[0073] In summary, according to the embodiments of the present disclosure, traffic lights can be detected and identified conveniently and quickly based on broadcast signals containing status data of traffic lights, which can avoid identification errors caused by environmental reasons and help improve the accuracy of detection and identification results. Furthermore, vehicles can be controlled based on the results of detection and identification of traffic lights, which helps to ensure traffic safety.
