[0038] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0039] When pedestrians turn their backs to moving vehicles or look down at their phones, it is difficult for them to notice the vehicles around them, especially electric vehicles. The electric drive system of an electric vehicle is different from the engine system of a traditional gasoline vehicle, and the noise generated during its operation is relatively small. At this time, the driver will generally use the horn to remind pedestrians, which will give pedestrians a disgusting experience and cause certain noise interference.

[0040] There are currently optimization solutions for car horns, such as adjustable speaker volume, which still bring a poor travel experience to pedestrians. There are also solutions based on 5G V2X, which use point-to-point communication between pedestrians and vehicles to prompt pedestrians to avoid vehicles when they turn their backs to moving vehicles or look down to play with their mobile phones. Although this can solve the problem of poor travel experience for pedestrians caused by car horns, it requires that the mobile phones, bracelets and other portable devices carried by pedestrians have 5GV2X hardware systems. At present, V2X technology has not been commercialized on a large scale and requires higher hardware and software service costs.

[0041] To this end, the present disclosure provides a pedestrian prompting method, which is assisted by network equipment such as mobile base stations, and pedestrians carry terminal devices such as mobile phones and bracelets with them, forming a communication closed loop between vehicle->network equipment->pedestrians. After discovering pedestrians, the moving vehicle can promptly prompt unaware pedestrians to remind pedestrians to pay attention to avoid vehicles, thereby avoiding the inconvenience caused to pedestrians by car honking. Compared with the solution based on 5G V2X, it is easy to implement and does not require high hardware and software service costs.

[0042] It can be understood that the solution provided in the present disclosure can be used for long term evolution communication technology (long term evolution, LTE), fifth generation mobile communication technology (Fifth Generation, 5G) and its subsequent communication technologies, such as fifth generation mobile communication technology evolution (5G-advanced), sixth generation mobile communication technology (Sixth Generation, 6G), etc., which are not limited in the present disclosure.

[0043] The following describes in detail a pedestrian prompting method, device, and electronic device proposed in the present disclosure in conjunction with the accompanying drawings.

[0044] Figure 1This is a flow chart of a pedestrian prompting method provided in an embodiment of the present disclosure. The method is applied to vehicles. The vehicles in the present disclosure mainly include motor vehicles, especially electric vehicles and self-driving vehicles that are not easily noticed by pedestrians, as well as dangerous vehicles, heavy trucks, trucks and other vehicles that are likely to cause serious accidents to pedestrians.

[0045] like Figure 1 As shown, the method comprises steps S101-S103.

[0046] S101, acquiring and sending the location information of the vehicle to a network device.

[0047] In an embodiment of the present disclosure, the vehicle computing chip calls the positioning chip to obtain positioning data, that is, to obtain the location information of the vehicle.

[0048] Optionally, for autonomous driving vehicles, more accurate location information of the vehicle can be obtained through the RTK positioning chip. The RTK positioning module is a standard configuration of the electric vehicle autonomous driving module and is located in the autonomous driving domain controller. Its function is to achieve centimeter-level positioning of the vehicle and realize lane-level autonomous driving applications.

[0049] In the implementation of the present disclosure, the network equipment mainly includes mobile base stations, etc., which can support communication between mobile devices within its network coverage, that is, the network equipment can realize communication with vehicles and mobile terminals of the first object within its network coverage.

[0050] In some embodiments of the present disclosure, the vehicle's location information can be transmitted to the vehicle's cabin controller via an on-board Ethernet link, and then transmitted to a network device through the mobile communication module of the cabin controller via an antenna. For example, based on the Internet of Vehicles technology, the location information of the vehicle can be transmitted through a 4G or 5G communication module via an antenna to a mobile base station within the coverage of the network signal.

[0051] S102, obtaining location information of a mobile terminal within a preset range from the vehicle and identification information of a first object from a network device, wherein the mobile terminal is bound to the first object through the identification information of the first object.

[0052] In an embodiment of the present disclosure, the first object includes pedestrians and cyclists on the road where vehicles are traveling, and the mobile terminal of the first object refers to a mobile device that the first object is carrying, mainly including a mobile phone, a smart bracelet, a smart watch, etc.

[0053] Specifically, the above-mentioned mobile terminals are usually equipped with an AGPS module, through which the location information of the mobile device can be tracked and the trajectory of pedestrians can be recorded.

[0054] Furthermore, the location information of the mobile terminal can be sent to the base station through the mobile communication module in the mobile terminal, so that through the AGPS module and the mobile communication module of the mobile terminal, the base station can obtain in real time the location information of the mobile terminals within its network coverage and the identification information of the first object bound to it, and based on the location information of the mobile terminals and the location information of the vehicle, determine the mobile terminals within the preset range of the vehicle, and then send the location information of the mobile terminals and the identification information of the first object bound to it to the vehicle.

[0055] In an embodiment of the present disclosure, the preset range can be pre-set according to the driving conditions of the vehicle. For example, for a dangerous vehicle, a larger preset range can be set, such as setting the range of 5m to 100m away from the vehicle in the driving direction of the vehicle as the preset range.

[0056] Optionally, since there is usually no need to alert pedestrians in scenarios such as highways, it can be set that when pedestrians are detected when the vehicle passes an intersection or open road during driving, the position of the mobile terminal within a preset range and the identification information of the first object bound to it are obtained.

[0057] For example, within a distance of 5m to 100m, there are mobile device 1 and mobile device 2, mobile device 1 is bound to pedestrian 1, the identification information of pedestrian 1 is A10086, mobile device 2 is bound to pedestrian 2, the identification information of pedestrian 2 is B20086.

[0058] S103: Collect an image of the first object bound to the mobile terminal according to the location information of the mobile terminal, and perform face recognition on the image.

[0059] In some embodiments, collecting an image of the first object bound to the mobile terminal and performing face recognition on the image includes: collecting an image of the first object bound to the mobile terminal through at least one vehicle-mounted camera; and performing face recognition on the image.

[0060] Specifically, a vehicle-mounted front camera can be used to collect images of pedestrians bound to a mobile terminal in front of the vehicle's road. The front-view camera is generally a wide-angle lens, which is divided into a medium-range camera and a long-range camera. It is installed on the rearview mirror inside the vehicle or at a higher position on the front windshield to achieve a longer effective distance. It can be used in medium or longer distances, such as at a distance of 90 to 250 meters. It can automatically detect pedestrians, cyclists, motorcycles, yellow lines on the roadside, bridge piers, curb traffic signs and signals, etc.

[0061] In some embodiments, after acquiring the image of the first object bound to the mobile terminal and before performing face recognition on the image, the method further includes: performing human body recognition on the image based on a preset human body model.

[0062] For example, an image of a first object bound to a mobile terminal is collected. Before performing face recognition on the collected image, the image is first input into a preset human body model to perform human body recognition on the image, wherein the preset human body model determines whether there is a human body shape in the image by extracting and comparing human features in the image.

[0063] In some embodiments, after performing human body recognition on an image based on a preset human body model, the method further includes: in response to not recognizing a human body in the image, performing no processing.

[0064] For example, an image of a first object bound to a mobile terminal is collected, the image is input into a preset human body model, and human body recognition is performed on the image. In response to no human body being recognized in the image, it is considered that there are no pedestrians within the preset range of the vehicle and no processing is performed.

[0065] Furthermore, in some embodiments, after performing human body recognition on the image based on a preset human body model, the method further includes: in response to recognizing a human body in the image, performing face recognition on the image based on a preset face model.

[0066] For example, an image of a first object bound to a mobile terminal is captured, and the image is first input into a preset human body model to perform human body recognition on the image. In response to recognizing a human body in the image, the image is input into a preset face model to perform face recognition on the image, wherein the preset face model determines whether there is a face in the image by extracting and comparing facial features in the image.

[0067] It should be noted that the present invention can perform human body recognition before performing face recognition on an image. If a human body is recognized, detailed facial feature recognition is not required when performing face recognition. Only basic facial form needs to be recognized, for example, only features such as facial features need to be recognized.

[0068] S104: In response to not acquiring the facial information of the first object, determining the identification information of the first object as first identification information, and sending the first identification information to the network device.

[0069] The first identification information is used to assist the network device in determining whether to send a prompt message to the mobile terminal of the first object according to whether the location information of the vehicle and the location information of the mobile terminal having the first identification information meet a preset distance condition.

[0070] Specifically, the vehicle's computing chip can perform facial recognition on pedestrians based on the collected images of pedestrians to detect whether facial information can be recognized. When facial information is recognized, it can be considered that the pedestrian has noticed the vehicle. When facial information is not recognized, it can be considered that the pedestrian is not aware of the vehicle, such as having his back to the vehicle, lowering his head, or having his vision blocked.

[0071] Optionally, this solution can be applied to autonomous driving vehicles. The autonomous driving computing unit can accurately identify situations where pedestrians are unaware of the vehicle, such as those with their backs to the vehicle. The autonomous driving computing unit includes the autonomous driving computing chip and its peripheral hardware circuits, as well as underlying software and upper-level algorithm applications.

[0072] In an embodiment of the present disclosure, if there are mobile terminal 1 and mobile terminal 2 within a preset range from the vehicle, an image of pedestrian 1 bound to mobile terminal 1 is collected for face recognition. If the face of pedestrian 1 is not detected, the identification information of pedestrian 1 is sent to the network device, and an image of pedestrian 2 bound to mobile terminal 2 is collected for face recognition. If the face of pedestrian 2 is detected, it is considered that pedestrian 2 has noticed the vehicle and there is no need to report it to the network device.

[0073] In summary, according to the embodiments of the present disclosure, the location information of the vehicle is obtained and sent to a network device; the location information of the mobile terminal and the identification information of the first object within a preset range from the vehicle are obtained from the network device, wherein the mobile terminal is bound to the first object through the identification information of the first object; according to the location information of the mobile terminal, an image of the first object bound to the mobile terminal is collected, and face recognition is performed on the image; in response to the face information of the first object not being obtained, the identification information of the first object is determined as the first identification information, and the first identification information is sent to the network device, wherein the first identification information is used to assist the network device to identify the first object according to the location information of the vehicle and the identification information of the first object; Whether the location information of the mobile terminal with the first identification information meets the preset distance condition is determined to determine whether to send a prompt message to the mobile terminal of the first object, so as to realize network-based auxiliary prompting of pedestrians to avoid moving vehicles, thereby bringing pedestrians a better travel experience. The embodiment of the present disclosure realizes from the vehicle side to obtain the location of pedestrians within a preset range through communication between the base station and the mobile terminal bound to the pedestrian. Through the on-board camera, the computing unit calculates the response to the failure to recognize the face of the pedestrian, reports the identification information of the pedestrian to the base station, and based on the base station, assists in prompting pedestrians to avoid vehicles, thereby avoiding the inconvenience caused to pedestrians by car honking. At the same time, it is easy to implement and does not require high hardware and software service costs.

[0074] Figure 2 A flowchart of a pedestrian prompting method provided in an embodiment of the present disclosure, the method is applied to a vehicle, and the present disclosure is for Figure 1 Further disclosure of the corresponding embodiments.

[0075] like Figure 2 As shown, the method includes steps S201-S209.

[0076] S201, obtaining and sending the vehicle's location information to a network device.

[0077] S202: Acquire location information of a mobile terminal within a preset range from the vehicle and identification information of a first object from a network device.

[0078] The mobile terminal is bound to the first object through the identification information of the first object.

[0079] S203: Collect an image of the first object bound to the mobile terminal according to the location information of the mobile terminal, and perform face recognition on the image.

[0080] In some embodiments, collecting an image of the first object bound to the mobile terminal and performing face recognition on the image includes: collecting an image of the first object bound to the mobile terminal through at least one vehicle-mounted camera; and performing face recognition on the image.

[0081] In some embodiments, after acquiring the image of the first object bound to the mobile terminal and before performing face recognition on the image, the method further includes: performing human body recognition on the image based on a preset human body model.

[0082] In some embodiments, after performing human body recognition on an image based on a preset human body model, the method further includes: in response to not recognizing a human body in the image, performing no processing.

[0083] Furthermore, in some embodiments, performing face recognition on an image includes: in response to recognizing a human body in the image, performing face recognition on the image based on a preset face model.

[0084] S202: In response to not acquiring facial information of the first object, determining identification information of the first object as first identification information, and sending the first identification information to a network device.

[0085] The first identification information is used to assist the network device in determining whether to send a prompt message to the mobile terminal of the first object according to whether the location information of the vehicle and the location information of the mobile terminal having the first identification information meet a preset distance condition.

[0086] The detailed explanation of the above steps S201-S204 can be found in Figure 1 Steps S101-S104 in the illustrated embodiment are not described in detail here.

[0087] S205: Determine whether the vehicle is in a preset danger zone based on the vehicle's location information.

[0088] In some embodiments, the preset danger areas include roads that do not have separate lanes for pedestrians and vehicles, intersections, sharp turns on the road, etc.

[0089] S206: In response to the vehicle being in a preset dangerous area, sending danger warning information to a network device.

[0090] The danger warning information is used to assist the network device in determining whether to send a second braking instruction to the vehicle.

[0091] In some embodiments, the network device determines to send a second braking instruction to the vehicle when it determines that the location information of the vehicle and the location information of the mobile terminal held by the first object meet a preset location condition and receives danger warning information sent by the vehicle.

[0092] S207, sending the vehicle status information to the network device, where the status information includes at least one of the type of vehicle, the speed of the vehicle, and the load status of the vehicle.

[0093] The status information is used to assist the network device in determining the danger level of the vehicle and send a first braking instruction and / or a second braking instruction to the vehicle at a preset distance based on the danger level of the vehicle, wherein the higher the danger level of the vehicle, the greater the preset distance.

[0094] In some embodiments, the type of vehicle includes trucks, coaches, buses, etc., the speed of the vehicle is the current speed of the vehicle, such as 35 km / h, and the load state of the vehicle is the current load state of the vehicle, such as fully loaded, unloaded, etc.

[0095] In some embodiments, the vehicle sends the vehicle status information to the network device in real time, such as sending the latest status information to the vehicle whenever the vehicle speed, load status, etc. changes.

[0096] In some embodiments, the vehicle's status information is used to assist the network device in determining the vehicle's danger level. The higher the vehicle's danger level, the greater the threat to pedestrians. The vehicle sends the vehicle's status information to the network device, and the network device issues a first braking command and / or a second braking command to the vehicle under different conditions based on the vehicle's danger level.

[0097] In some embodiments, the danger level of the vehicle is determined based on the type and / or speed and / or load status of the vehicle. For example, the danger level of the vehicle is higher when the vehicle is a truck carrying dangerous goods or the vehicle is a bus. The higher the load of the vehicle, the higher the danger level of the vehicle. The higher the speed of the vehicle, the higher the danger level of the vehicle.

[0098] In some embodiments, the higher the danger level of the vehicle, the greater the preset distance. For example, if the vehicle is a fully loaded truck, the danger level of the vehicle is determined to be high, and a braking command is issued when the vehicle is less than 100 meters away from the pedestrian. If the vehicle is an unloaded truck, the danger level of the vehicle is determined to be low, and a braking command is issued when the vehicle is less than 50 meters away from the pedestrian.

[0099] It should be noted that the above steps S205-S206 and S207 are optional steps, which can be implemented partially or in full. When steps S205-S206 and step S207 are both executed, the execution order between steps S205-S206 and step S207 is not disclosed and not restricted. Step S206 can be executed first and then steps S205-S206, or steps S205-S206 and step S207 can be executed at the same time, that is, the vehicle status information and danger warning information are sent to the network device at the same time.

[0100] S208: Receive a first braking instruction and / or a second braking instruction sent by the network device.

[0101] Among them, the first braking instruction is sent when the network device determines that the location information of the vehicle and the location information of the mobile terminal with the first identification information meet the preset location conditions and the identity of the first object meets the preset identity conditions. The second braking instruction is sent when the network device receives danger warning information, and the identity of the first object is determined by the network device based on the identification information of the first object sent by the mobile terminal with the first identification information.

[0102] In some embodiments, the first objects include pedestrians and cyclists on the road where the vehicle is traveling, and the identities of the first objects include ordinary groups and vulnerable groups such as the elderly, patients, disabled people, pregnant women, and children.

[0103] In some embodiments, the identity of the first object satisfies a preset identity condition including that the first object is a member of a vulnerable group.

[0104] In an embodiment of the present disclosure, when the first object is a vulnerable group such as the elderly, the disabled, etc., even if the vulnerable group has been prompted to avoid the vehicle through the network device, they are unable to avoid the vehicle in a short time due to their slow or inconvenient movements. At this time, the network device can send a braking command to the vehicle, so that the vehicle executes the braking command to avoid the vulnerable group.

[0105] In some embodiments, the identity information of the first object is stored in a mobile terminal bound to the first object. The first object with the first identification information does not notice the vehicle. After receiving the first identification information, the network device determines whether the first object is a vulnerable group. When the network device determines that the location information of the vehicle and the location information of the mobile terminal with the first identification information meet preset location conditions and the identity of the first object is a vulnerable group, a first braking command is sent to the vehicle.

[0106] In an embodiment of the present disclosure, when a vehicle is traveling in a preset dangerous area such as an intersection, the first object has been prompted by a network device to avoid the vehicle in a timely manner. However, due to complex road conditions, the driver of the vehicle cannot easily notice the first object and cannot take braking measures such as deceleration in time. At this time, a braking command can be sent to the vehicle through the network device, so that the vehicle executes the braking command to avoid the first object.

[0107] S209 , executing a vehicle braking operation in response to the first braking command and / or the second braking command.

[0108] In some embodiments, the first braking instruction and the second braking instruction are both types of braking instructions, which can be the same braking instruction or different braking instructions. Braking instructions include normal braking, emergency braking, etc. For example, the vehicle receives an emergency braking instruction sent by a network device, and the brakes are used to quickly stop the vehicle.

[0109] In summary, the present invention discloses a pedestrian prompting method, which obtains and sends the location information of a vehicle to a network device; obtains the location information of a mobile terminal within a preset range from the vehicle and the identification information of a first object from the network device, wherein the mobile terminal is bound to the first object through the identification information of the first object; according to the location information of the mobile terminal, collects an image of the first object bound to the mobile terminal, and performs face recognition on the image; in response to the failure to obtain the face information of the first object, determines the identification information of the first object as the first identification information, and sends the first identification information to the network device, wherein the first identification information is used to assist the network device in determining whether to send a prompting message to the mobile terminal of the first object according to whether the location information of the vehicle and the location information of the mobile terminal having the first identification information meet a preset distance condition, and can also synchronize the status information of the vehicle with the network device, and the vehicle sends a danger warning message to the network device when it is in a preset danger zone, and when the pedestrian is a vulnerable group or the vehicle travels to the danger zone, the vehicle can actively avoid the pedestrian by receiving the braking command issued by the network device, thereby avoiding the trouble caused to the pedestrian by the car honking, and it is easy to implement and does not require high hardware and software service costs.

[0143] like Figure 6 As shown, the method includes steps S601-S608.

[0144] S601, receiving location information of a vehicle, location information of a mobile terminal, and identification information of a first object, wherein the mobile terminal is bound to the first object through the identification information of the first object.

[0145] S602, sending the location information and identification of the mobile terminal within a preset range from the vehicle to the vehicle according to the location information of the vehicle and the location information of the mobile terminal.

[0149] The detailed explanation of the above steps S601-S604 can be found in Figure 2 Steps S501-S504 in the illustrated embodiment are not described in detail here.

[0150] S605: Determine the identity of the first object based on the first identification information and a pre-stored correspondence between the identification information and the identity.

[0151] In some embodiments, corresponding to step S104, the vehicle sends first identification information to the network device, the network device receives the first identification information, and determines the identity of the first object based on the first identification information and the correspondence between the pre-saved identification information and the identity, wherein the identity of the first object includes ordinary groups and vulnerable groups such as the elderly, patients, disabled people, pregnant women, and children.

[0152] S606, receiving status information sent by the vehicle.

[0153] The status information includes at least one of the type of vehicle, the speed of the vehicle, and the load status of the vehicle.

[0154] In some embodiments, the type of vehicle includes trucks, coaches, buses, etc., the speed of the vehicle is the current speed of the vehicle, such as 35 km / h, and the load state of the vehicle is the current load state of the vehicle, such as fully loaded, unloaded, etc.

[0156] S607: When the identity of the first object meets a preset identity condition, a first braking instruction is sent to the vehicle, where the first braking instruction is used to instruct the vehicle to perform a braking operation.

[0157] In some embodiments, the preset identity conditions include that the identity of the first object is a vulnerable group such as the elderly, the disabled, etc. It can be understood that when the pedestrian is a vulnerable group such as the elderly, the disabled, etc., even if the vulnerable group has been prompted by the base station to avoid the vehicle, they are slow or inconvenient to move and cannot avoid the vehicle in a short time. At this time, the network device can send a braking command to the vehicle to instruct the vehicle to actively avoid the vulnerable group.

[0159] In some embodiments, the danger warning information is sent by the vehicle to the network device in response to the vehicle's position being within a preset danger zone. The danger warning information is used to warn the vehicle that it is within the preset danger zone. The preset danger zone includes roads that do not have separate lanes for pedestrians and vehicles, intersections, sharp turns in the road, etc.

[0160] In an embodiment of the present disclosure, when a vehicle is traveling in a preset dangerous area such as an intersection, a first object has been prompted through a network device to avoid the vehicle in a timely manner. However, due to complex road conditions, the driver of the vehicle cannot easily notice the first object and cannot take braking measures such as deceleration in time. A second braking command is sent to the vehicle through the network device, causing the vehicle to execute the second braking command to avoid the first object.

[0161] Further, in some embodiments, sending a first braking command and / or a second braking command to the vehicle includes: determining a danger level of the vehicle based on status information sent by the vehicle, wherein the danger level of the vehicle includes two or more danger levels; based on the danger level, when the distance between the vehicle and the mobile terminal is less than a preset distance, sending a first braking command and / or a second braking command to the vehicle, wherein the higher the danger level of the vehicle, the greater the preset distance.

[0162] In some embodiments, the danger level of the vehicle is determined based on the type and / or speed and / or load status of the vehicle. For example, the danger level of the vehicle is higher when the vehicle is a truck carrying dangerous goods or the vehicle is a bus. The higher the load of the vehicle, the higher the danger level of the vehicle. The higher the speed of the vehicle, the higher the danger level of the vehicle.

[0163] In some embodiments, the higher the danger level of the vehicle, the greater the preset distance. For example, if the vehicle is a fully loaded truck, the danger level of the vehicle is determined to be high, and a braking command is issued when the vehicle is less than 100 meters away from the pedestrian. If the vehicle is an unloaded truck, the danger level of the vehicle is determined to be low, and the first braking command and / or the second braking command is issued when the vehicle is less than 50 meters away from the pedestrian.

[0164] It should be noted that the above steps S606 and S608 are optional steps and can be implemented partially or in full.

[0165] In summary, according to the embodiments of the present disclosure, when it is found from the network device side that a pedestrian is unaware of a vehicle and the pedestrian's position and the vehicle's position information meet preset conditions, a prompt is sent to the mobile terminal bound to the pedestrian to remind the pedestrian to avoid the vehicle, and the identity of the pedestrian is determined based on the identification information of the pedestrian who is unaware of the vehicle, and the danger warning information and status information sent by the vehicle are received. When the pedestrian is a vulnerable group or the vehicle travels into a dangerous area, a braking command is sent to the vehicle under different conditions based on the vehicle's status information, instructing the vehicle to brake and avoid pedestrians. This is particularly suitable for warning pedestrians, especially children, of dangerous vehicles, and avoids the inconvenience caused to pedestrians by car horns. It is easy to implement and does not require high hardware and software service costs.

[0178] S705: In response to not obtaining the facial information of the first object, the vehicle determines the identification information of the first object as the first identification information, and sends the first identification information to the network device.

[0179] S706: In response to receiving the first identification information, the network device determines whether the location information of the vehicle and the location information of the mobile terminal having the first identification information meet a preset distance condition.

[0180] S707: In response to the location information of the vehicle and the location information of the mobile terminal with the first identification information satisfying a preset distance condition, the network device sends a prompt message to the mobile terminal with the first identification information.

[0181] The prompt message is used to prompt the first object bound to the mobile terminal to avoid the vehicle.

[0193] It should be noted that steps S708-S709, steps S7010-7011, and step 7012 can be implemented selectively. Through steps S708-S709 and step 7012, when it is confirmed that the vehicle's location information and the mobile terminal's location information meet the preset distance conditions and the identity of the first object meets the preset identity conditions, for example, when the first object is less than 100m away from the vehicle and the first object is a vulnerable group, the network device sends a braking command to the vehicle, and the vehicle responds to the braking command and performs a vehicle braking operation to avoid the vulnerable group. Through steps S7010-7011 and step 7012, when it is confirmed that the vehicle's location information and the mobile terminal's location information meet the preset distance conditions and the vehicle is in a preset danger zone, for example, when the first object is less than 100m away from the vehicle and the vehicle is driving at an intersection, the network device sends a braking command to the vehicle, and the vehicle responds to the braking command and performs a vehicle braking operation.

After discovering pedestrians, the moving vehicle can promptly prompt the unaware pedestrians to remind the pedestrians to avoid the vehicles, thereby avoiding the inconvenience caused by car honking to pedestrians. Compared with the solution based on 5G V2X, it is easy to implement on a large scale and does not require high hardware and software service costs.
