[0044] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] In one embodiment, Figure 1 As shown, a roadside pedestrian protection method is provided. This embodiment uses the method applied to a terminal as an example for illustration. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0046] S110, obtaining a walking speed of a pedestrian when walking along a crosswalk, and a vehicle driving speed corresponding to a target vehicle on a target lane associated with the crosswalk.

[0047] Among them, the pedestrian crossing is also called a zebra crossing, which refers to a specific area on the road marked with zebra crossings for pedestrians to cross the road. The target lane associated with the pedestrian crossing refers to the lane where the target vehicle needs to pass through the corresponding pedestrian crossing during its driving process. The target vehicle can be a manned vehicle or an unmanned vehicle. The unmanned vehicle can include at least one of an unmanned sanitation vehicle, an unmanned logistics vehicle, and an unmanned inspection vehicle.

[0048] In an optional embodiment, the walking speed of pedestrians walking along the crosswalk and / or the vehicle speed corresponding to the target vehicle on the target lane associated with the crosswalk can be obtained through the roadside data collection module. The data collected by the road test data collection module can be sent to the terminal or server through the data sending module. Among them, the roadside data collection module can be installed at the traffic light or street light pole in front of the crosswalk, and the roadside data collection module can include at least one of a camera, an infrared sensor, and a speed sensor.

[0049] In another optional embodiment, the vehicle speed corresponding to the target vehicle can be collected by the on-board device on the target vehicle, and the vehicle information and vehicle speed corresponding to the target vehicle can be uploaded to the server. At the same time, the vehicle information is collected by the roadside data collection module, and the vehicle speed corresponding to the vehicle information is obtained from the server, thereby reducing the pressure of collecting the vehicle speed of the target vehicle and reducing the computing resource usage.

[0050] S120. Determine, based on the vehicle driving speed, a vehicle driving time corresponding to when the target vehicle drives to a first position of the crosswalk; the first position is a position of a crosswalk stop line in a travel direction of the target lane.

[0051] Among them, the pedestrian crossing stop line is a type of road traffic marking, specifically referring to the parking position of the target vehicle when approaching the pedestrian crossing. For a two-way lane, pedestrian crossing stop lines are set on both sides of the pedestrian crossing to indicate that the target vehicle stops before the pedestrian crossing stop line in its direction of travel.

[0052] In an optional embodiment, determining the vehicle travel time corresponding to the target vehicle traveling to the first position of the crosswalk based on the vehicle travel speed includes: when the target vehicle passes the target position, obtaining the vehicle travel speed of the target vehicle and the target distance from the target position to the first position, and determining the vehicle travel time based on the vehicle travel speed and the target distance.

[0053] S130. Determine the pedestrian walking time for the pedestrian to reach a second position of the crosswalk according to the pedestrian's walking speed; wherein the second position is a preset position in the pedestrian's walking direction corresponding to the traveling direction of the target lane.

[0054] In an optional embodiment, the target lane associated with the crosswalk includes a first lane and a second lane, and the traffic direction of the first lane is opposite to the traffic direction of the second lane. The first lane is close to the starting point of the crosswalk; the second lane is close to the end point of the crosswalk. If the target lane is the first lane, the second position is the midpoint of the crosswalk; if the target lane is the second lane, the second position is the end point of the crosswalk.

[0055] It is not difficult to understand that the safe position of pedestrians on the crosswalk is often different for target vehicles with different travel directions. When the target lane is only the first lane, since the first lane is close to the starting point of the crosswalk, pedestrians can ensure their safety by reaching the middle point of the crosswalk before the target vehicle reaches the corresponding crosswalk stop line. When the target lane is only the second lane, since the second lane is close to the end of the crosswalk, pedestrians can ensure their safety by reaching the end of the crosswalk before the target vehicle reaches the corresponding crosswalk stop line.

[0056] S140. Generate indication information based on the relationship between the vehicle driving time and the pedestrian walking time; wherein the indication information is used to indicate whether the pedestrian can safely cross the crosswalk.

[0057] Among them, the vehicle driving time can reflect the estimated time for the target vehicle to reach the stop line of the pedestrian crossing, and the pedestrian walking time can reflect the estimated time for the pedestrian to walk to the second position. The vehicle driving time is compared with the pedestrian walking time to provide safety instructions for pedestrians and ensure pedestrian safety.

[0058] In an optional embodiment, the instruction information may include waiting instruction information and passing instruction information. The waiting instruction information is used to instruct the pedestrian to wait for the target vehicle to pass, and the passing instruction information is used to instruct the pedestrian to pass quickly.

[0059] In an optional embodiment, the indication information may be played through a roadside alarm device. Optionally, the roadside alarm device may be set at a crosswalk. The roadside alarm device may include at least one of a display screen and a loudspeaker. Exemplarily, if the indication information is waiting indication information, the vehicle travel time may be displayed on the display screen in a countdown manner and updated in real time, and / or a waiting prompt may be played through voice, such as "The vehicle is about to pass, please wait in a safe area and do not pass through the crosswalk." Exemplarily, if the indication information is passing indication information, a passing prompt may be played through voice, such as "Please pass the crosswalk quickly."

[0060] In the embodiment of the present application, the vehicle driving time of the target vehicle to the stop line of the corresponding crosswalk is determined by the vehicle driving speed, and the pedestrian walking time of the pedestrian to the second position of the crosswalk is determined according to the pedestrian walking speed, so that the vehicle driving time is compared with the pedestrian walking time, and the indication information indicating whether the pedestrian has passed the crosswalk is generated, thereby ensuring the safety of pedestrians on the roadside and helping to reduce the risk of traffic accidents. In addition, by introducing the second position of the crosswalk, and the second position is determined by the traffic direction of the target lane, the safe position of the pedestrian on the crosswalk can be determined based on the traffic direction of the target lane where the target vehicle is located, which can adapt to different traffic scenes such as one-way lanes and multi-way lanes, and improve the scene adaptability and flexibility.

[0061] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment, in which the steps of generating the indication information are refined, including:

[0062] If the target lane is the first lane or the second lane, a waiting indication message is generated when the pedestrian walking time is greater than the vehicle driving time.

[0063] If the target lane is the first lane or the second lane, a traffic indication message is generated when the pedestrian walking time is not greater than the vehicle driving time.

[0064] If the target lane includes a first lane and a second lane, a traffic indication message is generated when the vehicle driving time corresponding to the first lane is greater than the pedestrian walking time corresponding to the first lane, and the vehicle driving time corresponding to the second lane is greater than the pedestrian walking time corresponding to the second lane.

[0065] If the target lane includes a first lane and a second lane, waiting indication information is generated when the vehicle driving time corresponding to the first lane is not greater than the pedestrian walking time corresponding to the first lane, or the vehicle driving time corresponding to the second lane is not greater than the pedestrian walking time corresponding to the second lane.

[0066] For ease of understanding, the following description will be given in conjunction with specific embodiments. For ease of distinction, the target vehicle in the first lane is referred to as the first target vehicle 210 , and the target vehicle in the second lane is referred to as the second target vehicle 220 .

[0067] like Figure 2A The figure shows an application scenario diagram of a roadside pedestrian protection method in an embodiment, where a pedestrian is preparing to walk from the starting point of a crosswalk to the end point of the crosswalk. The first target vehicle 210 is located in the first lane close to the starting point of the crosswalk. At this time, the second position is the midpoint of the crosswalk. The distance from the pedestrian to the midpoint of the crosswalk is d2. By obtaining the pedestrian's walking speed, the pedestrian walking time t1 corresponding to the first lane can be determined. The distance from the first target vehicle 210 to the corresponding stop line of the crosswalk is d1. By obtaining the vehicle driving speed of the first target vehicle 210, the vehicle driving time t2 corresponding to the first target vehicle 210 can be determined.

[0068] When the pedestrian walking time t1 is greater than the vehicle driving time t2, waiting instruction information is generated; when the pedestrian walking time t1 is not greater than the vehicle driving time t2, passing instruction information is generated.

[0069] like Figure 2B The figure shows an application scenario of the roadside pedestrian protection method in another embodiment, where a pedestrian is preparing to walk from the starting point of the crosswalk to the end point of the crosswalk. The second target vehicle 220 is located in the second lane close to the starting point of the crosswalk. At this time, the second position is the end point of the crosswalk. The distance from the pedestrian to the midpoint of the crosswalk is d4. By obtaining the pedestrian walking speed, the pedestrian walking time t3 corresponding to the second lane can be determined. The distance from the second target vehicle 220 to the corresponding stop line of the crosswalk is d3. By obtaining the vehicle driving speed of the second target vehicle 220, the vehicle driving time t4 corresponding to the second target vehicle 220 can be determined.

[0070] When the pedestrian walking time t3 is greater than the vehicle driving time t4, waiting instruction information is generated; when the pedestrian walking time t3 is not greater than the vehicle driving time t4, passing instruction information is generated.

[0071] like Figure 2B The figure shows an application scenario of a roadside pedestrian protection method in another embodiment, where a pedestrian is preparing to walk from the starting point of a crosswalk to the end point of the crosswalk. The first target vehicle 210 is located in the first lane near the starting point of the crosswalk, and the second target vehicle 220 is located in the second lane near the end point of the crosswalk. Similarly, the pedestrian walking time t1 corresponding to the first lane and the vehicle driving time t2 corresponding to the first target vehicle 210 can be determined; the pedestrian walking time t3 corresponding to the second lane and the vehicle driving time t4 corresponding to the second target vehicle 220 can be determined.

[0072] When the vehicle driving time t2 corresponding to the first lane is greater than the pedestrian walking time t1 corresponding to the first lane, and the vehicle driving time t4 corresponding to the second lane is greater than the pedestrian walking time t3 corresponding to the second lane, the passing instruction information is generated. When the vehicle driving time t2 corresponding to the first lane is not greater than the pedestrian walking time t1 corresponding to the first lane, or the vehicle driving time t4 corresponding to the second lane is not greater than the pedestrian walking time t3 corresponding to the second lane, the waiting instruction information is generated.

[0073] In the embodiment of the present application, only the type of the target lane and the relationship between the vehicle driving time and the pedestrian walking time are required, and then based on the above rules, the indication information can be quickly generated. The comparison process is relatively simple, which is conducive to improving the efficiency of generating indication information.

[0074] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment, in which another specific implementation of the energy recovery control method is provided.

[0075] See also Figure 3 Another roadside pedestrian protection method shown includes:

[0076] S310, obtaining the walking speed of pedestrians when walking along the crosswalk, and the vehicle driving speed corresponding to the target vehicle on the target lane associated with the crosswalk; the target lane associated with the crosswalk includes a first lane and a second lane; the traffic direction of the first lane is opposite to the traffic direction of the second lane; the first lane is close to the starting point of the crosswalk; the second lane is close to the end point of the crosswalk.

[0077] S320. Determine, based on the vehicle driving speed, the vehicle driving time corresponding to the first position of the crosswalk at which the target vehicle drives; the first position is the position of the crosswalk stop line in the travel direction of the target lane.

[0078] S330. Determine the pedestrian walking time for the pedestrian to reach the second position of the crosswalk according to the pedestrian's walking speed; if the target lane is the first lane, the second position is the midpoint of the crosswalk; if the target lane is the second lane, the second position is the end point of the crosswalk.

[0079] S340: If it is determined that the target lane is the first lane or the second lane, then S350 is executed.

[0080] S350: When the pedestrian's walking time is greater than the vehicle's driving time, generate waiting instruction information; when the pedestrian's walking time is not greater than the vehicle's driving time, generate passing instruction information.

[0081] S360: If the target lane is determined to be the first lane or the second lane, execute S370.

[0082] S370. When the vehicle driving time corresponding to the first lane is greater than the pedestrian walking time corresponding to the first lane, and the vehicle driving time corresponding to the second lane is greater than the pedestrian walking time corresponding to the second lane, generate a passing instruction message; when the vehicle driving time corresponding to the first lane is not greater than the pedestrian walking time corresponding to the first lane, or the vehicle driving time corresponding to the second lane is not greater than the pedestrian walking time corresponding to the second lane, generate a waiting instruction message.
