Description

Technical Field

[0001] The present invention relates to the field of automotive intelligent technologies, and in particular, to a monitoring and warning method, a storage medium, and an electronic device. Background Art

[0002] With the improvement of living standards, the number of vehicle holdings has also increased significantly, making the risk and probability of traffic accidents between vehicles increase substantially both during daily commuting and on holidays.

[0003] Therefore, for users driving vehicles, especially for various users with insufficient driving experience, whose attention is easily distracted during driving, who are very concerned about driving safety during driving, and who cherish their vehicles very much, there is an urgent need for an easy-to-implement and popularize method for rapid warning, so that not only can the warning opportunity be advanced as much as possible during the user's driving process, better improving the user's driving safety and driving experience, but also the rapid warning can be achieved through a simple and low-cost method. Summary of the Invention

[0004] The technical problem solved by the present invention is to provide a monitoring and warning method, a storage medium, and an electronic device to achieve rapid warning during driving through a simple and low-cost method.

[0005] To solve the above technical problem, the technical solution of the present invention provides a monitoring and warning method, including: dividing the communication channel of a first Wi-Fi into at least 2 sub-channels, where the first Wi-Fi is set in the vehicle; polling at least a part of the at least 2 sub-channels, and the polling method includes: broadcasting a probe request frame on each of the at least a part of the sub-channels, and receiving a plurality of probe response frames, where the probe response frames are responded by the Wi-Fi that obtains the probe request frame; when the number of the received probe response frames on one of the at least a part of the sub-channels is above a preset number, initiate a driving prompt in the vehicle to prevent the vehicle from colliding with other vehicles.

[0006] Correspondingly, the technical solution of the present invention also provides a storage medium, on which computer instructions are stored, and when the computer instructions are executed by a processor, the above-mentioned monitoring and warning method is implemented.

[0007] Correspondingly, the technical solution of the present invention also provides an electronic device, including a processor, a memory, a communication interface, and one or more programs, where the one or more programs are stored in the memory and are configured to be executed by the processor, and the programs include instructions for executing the steps in the above-mentioned monitoring and warning method.

[0008] Compared with the prior art, the technical solution of the embodiment of the present invention has the following beneficial effects:

[0009] In the monitoring and warning method provided by the technical solution of the present invention, the number of several probe response frames received on the sub-channel is used to infer the number of other vehicles around the vehicle. Due to the characteristics of the wifi installed on other vehicles based on wifi communication, at least a probe response frame is fed back after receiving a probe request frame. Therefore, this monitoring and warning method can initiate a driving prompt without obtaining the permission of other vehicles. At the same time, compared with the method of sending a probe frame and receiving a response frame including the driving data of other vehicles to implement a driving prompt after receiving a probe response frame, since the driving prompt is made according to the number of probe response frames, the warning speed of this monitoring and warning method is faster and the timing of initiating a driving prompt is earlier. At the same time, by dividing the communication channel of the first wifi into at least 2 sub-channels, several probe response frames sent by several wifis around the vehicle can be dispersed on each sub-channel to respond to the probe request frame, so that the number of probe response frames on each sub-channel is reduced. Therefore, through the polling and the judgment of the number of the probe response frames, while initiating a driving prompt for the vehicle, the amount of data that needs to be processed in parallel for initiating a driving prompt can be reduced, and the data interaction and processing speed for initiating a driving prompt can be accelerated. Thus, the warning speed is further accelerated and the timing of initiating a driving prompt is advanced. Therefore, the monitoring and warning method can achieve fast warning, greatly advance the timing of initiating a driving prompt, and has a good effect of improving driving safety. At the same time, since this monitoring and warning method uses the wifi hotspots commonly available in vehicles to broadcast probe request frames and receive probe response frames, this monitoring and warning method is easy to implement and promote, enabling users to simply and at low cost implement this monitoring and warning method. In summary, the monitoring and warning method can not only advance the warning timing as much as possible during the process of a user driving a vehicle to better enhance the driving safety and driving experience of the user, but also be implemented in a simple and low-cost manner.

[0017] As described in the background art, there is an urgent need for a method of rapid warning that is easy to implement and promote, so that not only can the warning opportunity be advanced as much as possible during the process of a user driving a vehicle to better improve the driving safety and driving experience of the user, but also the rapid warning can be realized in a simple and low-cost manner.

[0018] To solve the above technical problems, the technical solution of the present invention provides a monitoring and warning method. By polling at least a part of the at least 2 sub-channels, and when the number of the detection response frames received on one of the at least part of the sub-channels is above a preset number, a driving prompt is initiated in the vehicle itself. Thus, not only can the warning opportunity be advanced as much as possible during the process of a user driving a vehicle to better improve the driving safety and driving experience of the user, but also it can be realized in a simple and low-cost manner.

[0019] To make the above objects, features and beneficial effects of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings.

[0020] Figure 1 It is a flowchart of the monitoring and warning method according to an embodiment of the present invention.

[0021] The solution of this embodiment is executed by the vehicle side that initiates polling, and the vehicle side that initiates polling is the vehicle itself. The vehicle itself has vehicle electronic devices to implement the monitoring and warning method, and the vehicle electronic devices include: an in-vehicle terminal arranged on the vehicle itself, a mobile terminal capable of controlling the vehicle itself, etc.

[0022] Please refer to Figure 1 , the monitoring and warning method includes: Step S100, dividing the communication channel of the first wifi into at least 2 sub-channels, and the first wifi is arranged on the vehicle itself.

[0023] The communication channel of the first wifi is, for example, a 4G channel, a 5G channel, etc., and the rated transmission power of the first wifi is fixed due to hardware limitations.

[0024] In this embodiment, the monitoring and warning method further includes:

[0025] Step S101, select the Wi-Fi antenna type of the first Wi-Fi from the preset Wi-Fi antenna types, where the preset Wi-Fi antenna types include the front-and-back directional Wi-Fi antenna type and the omnidirectional Wi-Fi antenna type;

[0026] Step S102, adjust the signal gain mode of the first Wi-Fi according to the selected Wi-Fi antenna type of the first Wi-Fi.

[0027] The signal range of the front-and-back directional Wi-Fi antenna type is different from that of the omnidirectional Wi-Fi antenna type.

[0028] By selecting the preset Wi-Fi antenna type and correspondingly adjusting the signal gain mode of the first Wi-Fi, different signal ranges can be formed based on the rated transmission power of the first Wi-Fi.

[0029] Please refer to Figure 2 , Figure 2 , which is a schematic diagram of the signal range of the Wi-Fi antenna type according to an embodiment of the present invention. Compared with the omnidirectional Wi-Fi antenna type, when the front-and-back directional Wi-Fi antenna type is selected, the vehicle can detect signals at a farther distance in the X direction. Compared with the front-and-back directional Wi-Fi antenna type, when the omnidirectional Wi-Fi antenna type is selected, the detection distance of the signal in any direction around the vehicle is close. Therefore, through Step S101 and Step S102, a more suitable signal range of the first Wi-Fi can be selected according to factors such as the driving scenario and road conditions, thereby strengthening the pertinence of the monitoring and warning method for road conditions and improving the accuracy of driving reminders.

[0030] In some application scenarios, the vehicle is driving in some medium and low-speed driving scenarios such as urban ground roads where the speed requirement is below 80 KM / H. Generally, the overall road conditions in these application scenarios are complex. For example, the driving direction of vehicles changes frequently and there are many intersections between roads. It is necessary to monitor not only the vehicles in the front and back directions (X direction) of the vehicle, but also the vehicles in the left and right (Y direction) and other directions of the vehicle. Therefore, it is more suitable to monitor all vehicles within a certain distance around the vehicle for driving reminders. Thus, in these application scenarios, by selecting the omnidirectional Wi-Fi antenna type, the detection distance of the signal of the first Wi-Fi in any direction around the vehicle is close, thereby further enhancing driving safety.

[0031] In some other application scenarios, the vehicle is driving on an elevated road or a highway, or in some high-speed driving scenarios where the required vehicle speed is above 80 KM / H. Generally, in these application scenarios, there are few intersections between roads and many roads extending in the same direction. Therefore, compared with the road conditions in the Y direction, the road conditions in the X direction are more complex, and it is necessary to monitor vehicles farther away from the vehicle in the X direction to initiate driving reminders. Thus, in these application scenarios, by selecting the front and rear directional wifi antenna types, the first wifi can detect signals at a farther distance in the X direction, thereby further enhancing driving safety.

[0032] In this embodiment, the user sets the wifi antenna type of the first wifi on the in-vehicle electronic device.

[0033] In another embodiment, based on the road characteristics of the vehicle, such as whether it is on a highway or an elevated road, the in-vehicle electronic device autonomously selects the front and rear directional wifi antenna type or the omnidirectional wifi antenna type.

[0034] It should be noted that the execution order between step S101 and step S102 and step S100 has no impact on the effect of the technical solution of the present invention.

[0035] In this embodiment, the division of the at least 2 sub-channels is default-divided by the in-vehicle electronic device.

[0036] In this embodiment, the number of sub-channels is multiple.

[0037] In another embodiment, the number of sub-channels is 2.

[0038] Please continue to refer to Figure 1 , the method for monitoring and early warning further includes: step S200, grouping a plurality of sub-channels to form at least 2 channel groups, where each channel group includes at least 2 sub-channels.

[0039] It should be noted that the number of sub-channels included in each channel group can be the same or different.

[0040] In this embodiment, the channel groups are formed by default grouping by the in-vehicle electronic device.

[0041] In an application scenario, a mobile phone (the in-vehicle electronic device) capable of controlling the vehicle itself defaults to dividing the communication channel of the first Wi-Fi into sub-channels 1 to 14, and by default, groups sub-channels 1 to 14 to form channel groups 1 to 5. Among them, channel group 1 includes sub-channel 1, sub-channel 6, and sub-channel 11; channel group 2 includes sub-channel 2, sub-channel 7, and sub-channel 12; channel group 3 includes sub-channel 3, sub-channel 8, and sub-channel 13; channel group 4 includes sub-channel 4, sub-channel 9, and sub-channel 14; channel group 5 includes sub-channel 5 and sub-channel 10.

[0042] In another embodiment, multiple sub-channels are grouped through the settings of the user on the in-vehicle electronic device.

[0043] In an application scenario, an in-vehicle terminal (the in-vehicle electronic device) defaults to dividing the communication channel of the first Wi-Fi into sub-channels 1 to 12. The user groups sub-channels 1 to 12 through the settings on the in-vehicle terminal to form the channel groups desired by the user. Specifically, the user divides sub-channels 1 to 12 into channel groups 1 to 4. Among them, channel group 1 includes sub-channel 1, sub-channel 5, and sub-channel 9; channel group 2 includes sub-channel 2, sub-channel 6, and sub-channel 10; channel group 3 includes sub-channel 3, sub-channel 7, and sub-channel 11; channel group 4 includes sub-channel 4, sub-channel 8, and sub-channel 12.

[0044] In another embodiment, in the monitoring and warning method, multiple sub-channels are not grouped.

[0045] Please continue to refer to Figure 1 , the monitoring and warning method further includes: step S300, determining a priority inspection channel group among the at least 2 channel groups.

[0046] In the polling method of step S400 described later, the priority inspection channel group is used as the channel group for priority polling.

[0047] In another embodiment, in the monitoring and warning method, step S300 is not executed. In the polling of step S400 described later, polling starts from any one of the at least 2 channel groups.

[0048] In this embodiment, for step S300, the method for determining a priority inspection channel group among the at least 2 channel groups further includes:

[0049] Step S310, determining a priority inspection sub-channel among all sub-channels, and the channel group where the priority inspection sub-channel is located is the priority inspection channel group.

[0050] In the polling of step S400 described later, the preferred inspection sub-channel is used as the starting sub-channel for polling.

[0051] In this embodiment, the preferred inspection sub-channel is determined by the user's settings on the in-vehicle electronic device.

[0052] In an application scenario, the in-vehicle terminal defaults to grouping sub-channels 1 to 6 to form channel groups 1 to 3. Among them, channel group 1 includes sub-channel 1 and sub-channel 4; channel group 2 includes sub-channel 2 and sub-channel 5; channel group 3 includes sub-channel 3 and sub-channel 6. If the user sets sub-channel 5 as the preferred inspection sub-channel on the in-vehicle terminal, the in-vehicle terminal defaults the channel group 2 where sub-channel 5 is located as the preferred inspection channel group. Thus, in the polling of step S400 described later, sub-channel 5 serves as the starting sub-channel for polling, and sub-channel 2 in channel group 2 is the second sub-channel to be polled. After polling all the sub-channels included in channel group 2, the sub-channels included in channel groups 1 and 3 are polled.

[0053] In another embodiment, a preferred inspection sub-channel is determined by default by the in-vehicle electronic device.

[0054] In another embodiment, in the monitoring and warning method, step S310 is not executed. The preferred inspection channel group is selected by default by the in-vehicle electronic device.

[0055] In yet another embodiment, steps S200 and S300 are not executed. The monitoring and warning method further includes: step S210, determining a preferred inspection sub-channel among all the sub-channels. Specifically, the in-vehicle electronic device defaults one of the at least 2 sub-channels as the preferred inspection sub-channel. Or the user selects one of the at least 2 sub-channels and sets the selected sub-channel as the preferred inspection sub-channel on the in-vehicle electronic device.

[0056] Please continue to refer to Figure 1 , the monitoring and warning method further includes: step S400, polling at least a part of the at least 2 sub-channels.

[0057] Please combine Figure 1 with Figure 3 and Figure 4 , Figure 3 is a flowchart of the polling method according to an embodiment of the present invention, Figure 4 is a schematic diagram of an application scenario of the monitoring and warning method according to an embodiment of the present invention. The polling method includes:

[0058] Step S410, broadcasting a probe request frame on each of the at least a part of the sub-channels and receiving a plurality of probe response frames, where the probe response frames are responded by the wifi that obtains the probe request frame.

[0059] Specifically, the first Wi-Fi broadcasts a probe request frame on one of the at least two sub-channels. Then, based on the characteristics of Wi-Fi communication, several Wi-Fi devices that obtain the probe request frame on this sub-channel will respond to the probe request frame and send several probe response frames to the first Wi-Fi respectively. The first Wi-Fi receives several probe response frames on this sub-channel. After the first Wi-Fi completes the steps of broadcasting the probe request frame and receiving several probe response frames on this sub-channel, the first Wi-Fi continues to sequentially repeat the above steps on at least a part of the remaining sub-channels of the at least two sub-channels.

[0060] The number of several probe response frames received on the sub-channel is used to infer the number of other vehicles around the vehicle.

[0061] It should be understood that since the polling method is executed during the driving process of the vehicle, the signal range of the first Wi-Fi set on the vehicle is dynamically changing. Thus, the first Wi-Fi receives several probe response frames within its signal range, rather than necessarily being able to receive all the probe response frames that respond to the probe request frame.

[0062] For example, during the driving process of the vehicle, the first Wi-Fi broadcasts a probe request frame on sub-channel 1. The surrounding Wi-Fi hotspots A, B, and C all receive the probe request frame on sub-channel 1. Moreover, Wi-Fi hotspot A sends a probe response frame A1 to the first Wi-Fi on sub-channel 1, Wi-Fi hotspot B sends a probe response frame B1 to the first Wi-Fi on sub-channel 1, and Wi-Fi hotspot C sends a probe response frame C1 to the first Wi-Fi on sub-channel 1. However, the signal range of the first Wi-Fi changes as the vehicle travels, and the distance between Wi-Fi hotspot A and the vehicle also changes. When the distance between Wi-Fi hotspot A and the first Wi-Fi of the vehicle becomes larger, the signal of Wi-Fi hotspot A is outside the signal range of the first Wi-Fi. At this time, although Wi-Fi hotspot A sends a probe response frame A1 to the first Wi-Fi on sub-channel 1, the first Wi-Fi cannot receive the probe response frame A1. At the same time, Wi-Fi hotspots B and C still maintain a relatively close distance from the first Wi-Fi of the vehicle. The signal of Wi-Fi hotspot B is within the signal range of the first Wi-Fi, and the signal of Wi-Fi hotspot C is within the signal range of the first Wi-Fi. Thus, the first Wi-Fi receives the probe response frame B1 and the probe response frame C1 on sub-channel 1.

[0063] Since the reason that the first Wi-Fi cannot receive the probe response frame is that the distance between the Wi-Fi that sends the probe response frame and the first Wi-Fi is relatively large, in the polling method, the first Wi-Fi can filter out the probe response frames sent by other vehicles that are far away from the vehicle or other interfering probe response frames, so that the accuracy of the driving prompt initiated by the vehicle later is relatively good.

[0064] The other interfering probe responses are, for example, the Wi-Fi set in the street shops or the Wi-Fi set on the mobile phones of the pedestrians on the roadside.

[0065] In this embodiment, for step S410, the method of broadcasting the probe request frame on each of the at least a part of the sub-channels further includes: step S411, broadcasting the probe request frame once on each of the at least a part of the sub-channels. Thus, it is possible to quickly poll each of the at least a part of the sub-channels, further accelerating the warning speed and the timing of initiating the driving prompt.

[0066] In another embodiment, step S411 is not executed. For step S410, the method of broadcasting the probe request frame on each of the at least a part of the sub-channels further includes: step S412, broadcasting the probe request frame on the sub-channel according to a preset period. Thus, the risk of the accuracy of the driving prompt decreasing due to data packet loss during the polling process is reduced, and the driving safety of the user is further improved.

[0067] In this embodiment, the probe request frame includes the SSID of the first Wi-Fi, and the SSID of the first Wi-Fi includes at least a custom field.

[0068] The custom field is used to prevent hotspot conflicts between the first Wi-Fi and other Wi-Fi.

[0069] In another embodiment, the SSID of the first Wi-Fi further includes a vehicle optional field, and the vehicle optional field is used to distinguish the model of the vehicle, so that other vehicles that obtain the probe request frame can initiate a driving prompt for preventing collisions of expensive vehicles.

[0070] In another embodiment, the SSID of the first Wi-Fi includes a custom field and a vehicle optional field.

[0071] Please continue to refer to Figure 3 and Figure 4 , the polling method further includes: step S420, starting the polling from the excellent detection channel group.

[0072] Please refer to Figure 3 and Figure 5 , Figure 5FIG. 0 is a schematic flowchart of a method for starting polling from a self-optimized detection channel group. For step S420, the method for starting the polling from the self-optimized detection channel group further includes:

[0073] Step S421: Poll the sub-channels of the self-optimized detection channel group starting from the self-optimized sub-channel;

[0074] Step S422: After polling all the sub-channels in the self-optimized detection channel group, poll the sub-channels in the channel groups other than the self-optimized detection channel group among the at least two channel groups.

[0075] In an application scenario, the communication channels of the first Wi-Fi are divided into sub-channels 1 to 6, and sub-channels 1 to 6 are grouped to form channel groups 1 to 3. Among them, channel group 1 includes sub-channels 1 and 4; channel group 2 includes sub-channels 2 and 5; channel group 3 includes sub-channels 3 and 6. And sub-channel 4 is set as the self-optimized sub-channel. Correspondingly, channel group 1 is defaulted as the self-optimized detection channel group. Thus, sub-channel 4 is the starting sub-channel for the first Wi-Fi to perform the polling. When the first Wi-Fi completes the steps of broadcasting a probe request frame and receiving a number of probe response frames on sub-channel 4, it continues to poll sub-channel 1 in channel group 1 and repeats the steps on sub-channel 4. When the first Wi-Fi polls all the sub-channels in channel group 1, it continues to poll the sub-channels in channel groups 2 and 3.

[0076] In another embodiment, steps S310, S421, and S422 are not executed, and the self-optimized detection channel group is default selected by the in-vehicle electronic device. On this basis, for step S420, the method for starting the polling from the self-optimized detection channel group further includes: Step S423: Start polling from any one of the sub-channels in the self-optimized detection channel group.

[0077] In another embodiment, steps S300 and S420 are not executed. On this basis, for step S400, the method for polling further includes: Step S401: Start polling from any one of the at least two channel groups.

[0078] In yet another embodiment, steps S200, S300, and S420 are not executed. The monitoring and warning method further includes: Step S210: Determine a self-optimized sub-channel among all the sub-channels. On this basis, for step S400, the method for polling further includes: Step S402: Poll at least a part of the at least two sub-channels starting from the self-optimized sub-channel.

[0079] Please continue to refer to Figure 3 and Figure 4, for step S400, the polling method further includes: step S430, starting from the broadcast of the probe request frame on the sub-channel, receiving a plurality of probe response frames that respond to the probe request frame within a preset duration.

[0080] Specifically, during the execution of step S410, starting from the broadcast of the probe request frame on the sub-channel by the first wifi, it only receives a plurality of probe response frames that respond to the probe request frame within a preset duration on this sub-channel. Thus, by setting the preset duration, it is possible to further filter out the probe response frames sent by other vehicles that are far away from the vehicle or other interfering probe response frames, further accelerating the data interaction and processing speed for initiating driving prompts, so that the warning speed and the timing of initiating driving prompts are further advanced. At the same time, the initiated driving prompts have better accuracy.

[0081] In another embodiment, step S430 is not executed.

[0082] Please continue to refer to Figure 3 and Figure 4 , for step S400, the polling method further includes: step S440, when the number of the received probe response frames on one of the at least a part of sub-channels is above a preset number, stop the polling.

[0083] The preset number is used to judge whether to initiate a driving prompt for a high-density traffic flow following warning for the vehicle. The preset number is the default of the vehicle's electronic device, or the preset number is set by the user on the vehicle's electronic device.

[0084] Since the polling is stopped when the number of the received probe response frames is above the preset number, in step S500 described later, the vehicle will not initiate driving prompts frequently. Thus, during the driving process, the user can receive driving prompts, improving the driving attention to avoid vehicles, and at the same time, will not be affected by frequent driving prompts. Furthermore, while improving driving safety, the user driving experience is further enhanced.

[0085] In another embodiment, step S440 is not executed, and for step S400, each of the at least 2 sub-channels is polled.

[0086] Since all sub-channels are polled, when the number of the received probe response frames on each sub-channel is above the preset number, driving prompts can be obtained through step S500 described later. Thus, the user can more strongly feel that the density of other vehicles around the vehicle is relatively large. Furthermore, the user's driving vigilance can be greatly enhanced to better improve driving safety.

[0087] Please continue to refer to Figure 3and Figure 4 For step S400, the polling method further includes: step S450, performing the polling according to a preset polling period.

[0088] In this embodiment, the preset polling period is the default period of the vehicle's electronic device.

[0089] In another embodiment, the preset polling period is a period set by the user on the vehicle's electronic device.

[0090] For example, the preset polling period is to perform the polling once every 10 minutes, three times every 15 minutes, and so on.

[0091] Since the polling is performed according to the preset polling period, the performance impact of processing the warning data on the vehicle's electronic device is further reduced, enabling the user to obtain driving tips while also making the user's use of the vehicle's electronic device smoother, thereby enhancing the user experience.

[0092] Please continue to refer to Figure 1 and Figure 4 The monitoring and warning method further includes: step S500, when the number of the detected response frames received on one of the at least a part of the sub-channels is above a preset number, initiate a driving tip in the vehicle to prevent the vehicle from colliding with other vehicles.

[0093] Due to the characteristics of the wifi communication of the other vehicle, at least a detected response frame is fed back after receiving the detected request frame. Therefore, this monitoring and warning method can initiate a driving tip without obtaining the permission of the other vehicle. At the same time, compared with the method of sending a detected frame and receiving a response frame including the driving data of the other vehicle to achieve a driving tip after receiving the detected response frame, since the driving tip is initiated according to the number of the detected response frames, the warning speed of this monitoring and warning method is faster and the timing of initiating the driving tip is earlier. At the same time, by dividing the communication channel of the first wifi into at least 2 sub-channels, the several detected response frames sent by several wifis around the vehicle can be dispersed to respond to the detected request frames on each sub-channel, so that the number of the detected response frames on each sub-channel is reduced. Therefore, through the polling and the judgment of the number of the detected response frames, the amount of data that needs to be processed in parallel for initiating the driving tip can be reduced while initiating the driving tip in the vehicle, and the data interaction and processing speed for initiating the driving tip can be accelerated, thereby further accelerating the warning speed and advancing the timing of initiating the driving tip.

[0094] Therefore, the monitoring and warning method can achieve rapid warning, greatly advance the timing of initiating driving prompts, and has a good effect on improving driving safety. At the same time, since the monitoring and warning method uses the wifi hotspots commonly available in vehicles to broadcast probe request frames and receive probe response frames, the monitoring and warning method is easy to implement and promote, enabling users to implement the monitoring and warning method simply and at low cost. In summary, the monitoring and warning method can not only advance the warning timing as much as possible during the process of a user driving a vehicle to better enhance the driving safety and driving experience of the user, but also be implemented in a simple and low-cost manner.

[0095] Specifically, for step S500, when the number of the received probe response frames on one of the at least a part of sub-channels is above a preset number, a driving prompt for high-density traffic flow following warning is initiated in the vehicle itself.

[0096] Please continue to refer to Figure 1 and Figure 4 , the monitoring and warning method further includes: step S600, when receiving a plurality of probe response frames in response to the probe request frame on the sub-channel, measuring the signal strengths of a plurality of wifis that send the plurality of probe response frames, and obtaining a plurality of signal strengths corresponding to the plurality of probe response frames.

[0097] The signal strength is used to infer the distance between the sending side of the corresponding probe response frame and the vehicle itself, so as to perform the driving prompt in step 800 described later.

[0098] There is a one-to-one correspondence between the probe response frame received by the first wifi on the sub-channel, the wifi that sends the probe response frame, and the signal strength obtained by measuring the probe response frame.

[0099] For example, the first wifi receives probe response frame D1, probe response frame D2, and probe response frame D3 on a sub-channel respectively. And when receiving probe response frame D1, measuring the signal strength of wifi hotspot M1 that sends probe response frame D1, and obtaining signal strength K1. When receiving probe response frame D2, measuring the signal strength of wifi hotspot M2 that sends probe response frame D2, and obtaining signal strength K2. When receiving probe response frame D3, measuring the signal strength of wifi hotspot M3 that sends probe response frame D3, and obtaining signal strength K3. Then, there is a correspondence between probe response frame D1, wifi hotspot M1, and signal strength K1, a correspondence between probe response frame D2, wifi hotspot M2, and signal strength K2, and a correspondence between probe response frame D3, wifi hotspot M3, and signal strength K3.

[0100] In this embodiment, although there is a one-to-one correspondence among the probe response frames received by the first Wi-Fi on the sub-channel, the Wi-Fi that sends the probe response frames, and the signal strength obtained by measuring the probe response frames, the in-vehicle electronic device does not store their corresponding relationship. Therefore, the performance impact of processing warning data on the in-vehicle electronic device is further reduced, enabling the user to receive driving prompts while also making the user's use of the in-vehicle electronic device smoother, thereby enhancing the user experience.

[0101] In another embodiment, the in-vehicle electronic device stores the corresponding relationship among the probe response frames received by the first Wi-Fi on the sub-channel, the Wi-Fi that sends the probe response frames, and the signal strength obtained by measuring the probe response frames. Thus, the steps S720 to S730 described later can be implemented.

[0102] Please continue to refer to Figure 1 and Figure 4 , the monitoring and warning method further includes: step S700, obtaining a plurality of measurement distances between the vehicle and a plurality of Wi-Fi that send the plurality of probe response frames according to a plurality of signal strengths corresponding to the plurality of probe response frames.

[0103] In this embodiment, the in-vehicle electronic device stores a database, which includes a plurality of non-overlapping signal strength ranges and a plurality of measurement distances corresponding to each signal strength range. The in-vehicle electronic device obtains the measurement distance corresponding to the measured signal strength according to the database and the measured signal strength.

[0104] In another embodiment, the in-vehicle electronic device stores a measurement model, and through the measurement model, the in-vehicle electronic device can calculate the measurement distance corresponding to the obtained signal strength according to the obtained signal strength.

[0105] In this embodiment, for step S700, obtaining a plurality of measurement distances between the vehicle and a plurality of Wi-Fi that send the plurality of probe response frames means obtaining the measurement distances corresponding to all signal strengths. Since the obtained data is more comprehensive, therefore, in combination with step S800 described later, it is beneficial to initiate driving prompts with a wider range for the vehicle to further improve the driving safety of the user.

[0106] In another embodiment, for step S700, the method of obtaining a plurality of measured distances between the vehicle itself and a plurality of WiFis that send a plurality of probe response frames according to a plurality of signal strengths further includes: step S710, when the number of the probe response frames received on one of the at least a part of sub-channels is above a preset number, obtaining a plurality of measured distances between the vehicle itself and a plurality of WiFis that send a plurality of probe response frames according to a plurality of signal strengths. Therefore, in combination with step S800 described subsequently, while giving a driving prompt and improving driving safety, it takes into account reducing the data processing and operations for obtaining the measured distances, further improving the warning speed, and facilitating further advancing the warning timing.

[0107] In another other embodiment, for step S700, the method of obtaining a plurality of measured distances between the vehicle itself and a plurality of WiFis that send a plurality of probe response frames according to a plurality of signal strengths further includes:

[0108] Step S720, sorting the plurality of signal strengths to obtain a sorting result;

[0109] Step S730, obtaining a plurality of measured distances according to a plurality of signal strengths within a preset sorting threshold in the sorting result.

[0110] The preset sorting threshold is the default of the in-vehicle electronic device, or the preset sorting threshold is set by the user on the in-vehicle electronic device. For example, if the preset sorting threshold is 3, then three corresponding measured distances are obtained according to the signal strengths of the top 3 in the sorting result.

[0111] Since a plurality of measured distances are obtained according to a plurality of signal strengths within a preset sorting threshold in the sorting result, therefore, in combination with step S800 described subsequently, it is possible to monitor other vehicles with high danger and give a driving prompt to improve driving safety. At the same time, it takes into account reducing the data processing and operations for obtaining the measured distances, further improving the warning speed, and facilitating further advancing the warning timing.

[0112] Please continue to refer to Figure 1 and Figure 4 , the monitoring and warning method further includes: step S800, when the measured distance is within a preset vehicle distance range, giving a driving prompt that the distance of the other vehicle is relatively close in the vehicle itself.

[0113] The preset vehicle distance range is the default of the in-vehicle electronic device, or the preset vehicle distance range is set by the user on the in-vehicle electronic device.

[0114] Through steps S600 to S800, when the user is driving a vehicle, the user can more specifically know the distance situation between the other vehicle and the vehicle itself, thereby further improving the user's vigilance awareness and enhancing the user's driving safety.

[0115] Please continue to refer to Figure 1 and Figure 4 , the monitoring and warning method further includes: Step S900, when the detection response frame includes an SSID with an optional field, according to the optional field, initiate a driving prompt for preventing expensive vehicle collisions in the vehicle itself, where the optional field is used to distinguish the models of other vehicles.

[0116] Thus, during driving, by using the obtained detection response frame, the vehicle itself can also initiate a driving prompt based on the vehicle of a specified model and a specified brand, reducing the risk of high-cost repairs and high-cost compensation. Therefore, the types and pertinence of the driving prompts are improved to enhance the user experience.

[0117] Figure 6 is a schematic flowchart of the monitoring and warning method according to another embodiment of the present invention.

[0118] Please refer to Figure 6 , the monitoring and warning method includes:

[0119] Step S1000, divide the communication channel of the first wifi into at least 2 sub-channels, where the first wifi is set in the vehicle itself;

[0120] Step S2000, group the multiple sub-channels to form at least 2 channel groups, where each channel group includes at least 2 sub-channels;

[0121] Step S3000, determine the preferred inspection channel group among the at least 2 channel groups;

[0122] Step S4000, poll at least a part of the at least 2 sub-channels.

[0123] The difference between Step S1000 to Step S4000 in this embodiment and Figure 1 Step S100 to Step S400 in the embodiment shown is that the SSID of the first wifi includes a fixed field and a custom field. The fixed field is the non-changeable field in the SSID of the first wifi, and the fixed field is used in Step S5000 described later to determine whether the received detection response frame is sent by the wifi set in other vehicles, so as to further improve the accuracy of the driving prompt. On this basis, the specific implementation principles and logics of the two are the same. Therefore, the explanations of other nouns involved in Step S1000 to Step S4000 can refer to Figure 1 the relevant descriptions of the embodiment shown, which will not be elaborated here.

[0124] Please continue to refer to Figure 6 , the monitoring and warning method further includes:

[0125] Step S5000: Determine whether the probe response frame received on one of the at least part of the sub-channels is responded by a second Wi-Fi, where the second Wi-Fi is set in another vehicle.

[0126] Please refer to Figure 7 , Figure 7 FIG. is a schematic flowchart for judging the sending side of the probe response frame according to another embodiment of the present invention. For step S5000, the method for determining whether the probe response frame received on one of the at least part of the sub-channels is responded by a second Wi-Fi further includes:

[0127] Step S5100: Determine whether the probe response frame includes an SSID with the fixed field.

[0128] Step S5200: When the probe response frame includes an SSID with the fixed field, the probe response frame is responded by the second Wi-Fi.

[0129] Through step S5100 and step S5200, the sending side of the probe response frame can be screened in a simple manner to determine whether the probe response frame received on one of the at least part of the sub-channels is sent by the Wi-Fi (second Wi-Fi) of another vehicle or some other interfering probe response frames.

[0130] Please continue to refer to Figure 6 , the monitoring and warning method further includes:

[0131] Step S6000: Obtain the number of probe response frames received on one of the at least part of the sub-channels and responded by the second Wi-Fi.

[0132] Step S7000: When the number of probe response frames received on one of the at least part of the sub-channels and responded by the second Wi-Fi is above a preset number, initiate a driving prompt in the vehicle to prevent the vehicle from colliding with another vehicle.

[0133] Specifically, for step S7000, when the number of probe response frames received on one of the at least part of the sub-channels and responded by the second Wi-Fi is above a preset number, initiate a driving prompt for high-density traffic flow following warning in the vehicle.

[0134] Through steps S5000 to S7000, the sending side of the probe response frame is screened to remove some other interfering probe response frames. Therefore, the monitoring and warning method can not only advance the warning timing, is easy to implement and popularize, but also further improve the warning accuracy of the driving prompt, thus better enhancing the user experience.

[0135] Please continue to refer to Figure 6 , the method for monitoring and early warning further includes:

[0136] Step S8000, when receiving a plurality of probe response frames in response to the probe request frame on the sub-channel, measure the signal strengths of a plurality of wifis that send the plurality of probe response frames, and obtain a plurality of signal strengths corresponding to the plurality of probe response frames.

[0137] Step S8000 in this embodiment and Figure 1 Step S600 in the illustrated embodiment have the same specific implementation principles and logics. Therefore, the explanations of the terms involved in Step S8000 can refer to Figure 1 the relevant descriptions of the illustrated embodiment, which will not be elaborated here.

[0138] Please continue to refer to Figure 6 , the method for monitoring and early warning further includes: Step S9000, according to the plurality of signal strengths corresponding to the plurality of probe response frames, obtain a plurality of measurement distances between the vehicle itself and a plurality of second wifis that send the plurality of probe response frames.

[0139] In this embodiment, a database is stored in the vehicle electronic device, and the database includes a plurality of non-overlapping signal strength ranges and a plurality of measurement distances corresponding to each signal strength range. The vehicle electronic device obtains the measurement distance corresponding to the measured signal strength according to the database and the measured signal strength.

[0140] In another embodiment, a measurement model is stored in the vehicle electronic device, and the vehicle electronic device can calculate the measurement distance corresponding to the obtained signal strength through the measurement model.

[0141] In this embodiment, for Step S9000, obtaining a plurality of measurement distances between the vehicle itself and a plurality of second wifis that send the plurality of probe response frames means obtaining the measurement distances corresponding to all the signal strengths corresponding to the second wifis.

[0142] In this embodiment, through step S5000, step S6000, and step S9000, it is possible to screen the measurement distances to be obtained, reduce the measurement intervals corresponding to some other interfering detection response frames, thereby not only reducing the data processing and operations for obtaining the measurement intervals, further improving the warning speed, facilitating the further advancement of the warning timing, but also improving the accuracy of the driving prompts initiated by the vehicle itself, reducing incorrect driving prompts, and enhancing the user experience. Moreover, since the measurement intervals corresponding to all signal strengths corresponding to the second wifi are obtained, the data for obtaining the measurement intervals is relatively comprehensive. Therefore, it is beneficial to initiate driving prompts with a wider range for the vehicle itself to further improve the driving safety of the user.

[0143] In another other embodiment, for step S9000, the obtaining of a plurality of measurement intervals between the vehicle and a plurality of second wifis that send a plurality of detection response frames according to a plurality of signal strengths corresponding to the plurality of detection response frames further includes:

[0144] Step S9100, when the number of detection response frames responded by the second wifi received on one of the at least a part of sub-channels is above a preset number, obtaining a plurality of measurement intervals between the vehicle and a plurality of second wifis that send a plurality of detection response frames according to a plurality of signal strengths. Therefore, in combination with step S10000 described subsequently, while performing driving prompts and improving driving safety, it takes into account reducing the data processing and operations for obtaining the measurement intervals, further improving the warning speed, and facilitating the further advancement of the warning timing.

[0145] In another other embodiment, for step S9000, the obtaining of a plurality of measurement intervals between the vehicle and a plurality of second wifis that send a plurality of detection response frames according to a plurality of signal strengths corresponding to the plurality of detection response frames further includes:

[0146] Step S9200, sorting the plurality of signal strengths corresponding to the plurality of second wifis to obtain a sorting result;

[0147] Step S9300, obtaining a plurality of measurement intervals according to a plurality of signal strengths within a preset sorting threshold in the sorting result.

[0148] It should be understood that the plurality of measurement intervals in step S9300 refer to the plurality of measurement intervals between the vehicle and a plurality of second wifis corresponding to a plurality of signal strengths within the preset sorting threshold.

[0149] Since a plurality of measurement intervals are obtained based on a plurality of signal strengths within a preset sorting threshold in the sorting result, therefore, in combination with step S10000 described in the following, while reducing incorrect driving prompts, it is not only possible to monitor other vehicles with high danger and give driving prompts to improve driving safety, but also takes into account reducing the data processing and operations for obtaining the measurement intervals, further improving the warning speed, which is conducive to advancing the warning timing further ahead.

[0150] Please continue to refer to Figure 6 , the monitoring and warning method further includes: step S10000, when the measurement interval is within a preset vehicle distance range, give a driving prompt that the distance of other vehicles is relatively close in the vehicle itself.

[0151] The preset vehicle distance range is the default of the vehicle's electronic device, or the preset vehicle distance range is set by the user on the vehicle's electronic device.

[0152] Correspondingly, an embodiment of the present invention further provides a storage medium, on which computer instructions are stored, and when the computer instructions are executed by a processor, the monitoring and warning method described in any one of the above is implemented.

[0154] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be subject to the scope defined by the claims.
