[0056] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0057] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0058] The main solution of the embodiment of the present application is: obtaining the current longitude and latitude of the target vehicle and the current risk area; when the target vehicle starts a risk reminder, obtaining the risk status of the target vehicle according to the current longitude and latitude and the current risk area; obtaining risk reminder information according to the risk status; sending the risk reminder information to the vehicle side, so that the vehicle side reminds the user of the risk area based on the risk reminder information.

[0059] In this embodiment, for ease of description, the following description is made by taking the identification of a vehicle-based risk area reminder device as the execution subject.

[0060] Since the current vehicle-related safety and prompt reminders are mainly obtained by obtaining vehicle status or road-related data from the server, voice broadcasts and pop-up reminders are made on the vehicle side. For example, if the vehicle seat belt is not fastened from the vehicle status and congestion data is obtained from the server, the current vehicle navigation system's route calculation preferences support users to achieve travel preferences such as avoiding congestion and giving priority to highways through active settings.

[0061] Vehicle safety is not only related to the state of the vehicle itself, but also to changes in the external environment. Some changes in the external environment can be observed by the driver, but there are also safety factors that cannot be observed and require early warning. Currently, drivers cannot avoid areas with abnormal accidents in time while driving, resulting in restricted vehicle driving and affecting the normal use of users' vehicles.

[0062] The present application provides a solution, which obtains the vehicle's latitude and longitude information and the current risk area to accurately determine whether the vehicle is in or close to the risk area, thereby ensuring the accuracy of subsequent reminders, and generating corresponding risk reminder information based on the risk status. By sending the risk reminder information to the vehicle side, the user can receive the risk reminder information in time, and avoid areas with abnormal accidents in time based on the risk reminder information, thereby ensuring the user's normal driving and enhancing the user's driving safety.

[0063] It can be seen from the above embodiments that the present application discloses a vehicle-based risk area reminder method, device, equipment and storage medium, which relates to the field of vehicle communication technology, and discloses: obtaining the current longitude and latitude and the current risk area of ​​the target vehicle; when the target vehicle starts the risk reminder, the risk status of the target vehicle is obtained according to the current longitude and latitude and the current risk area; risk reminder information is obtained according to the risk status; the risk reminder information is sent to the vehicle side, so that the vehicle side reminds the user of the risk area based on the risk reminder information; the method obtains the longitude and latitude information of the vehicle and the current risk area, accurately determines whether the vehicle is in or close to the risk area, ensures the accuracy of subsequent reminders, and generates risk reminder information based on the risk status, and based on, by sending the risk reminder information to the vehicle side, the user can receive the risk reminder information in time, and avoid the area with abnormal accidents in time based on the risk reminder information, thereby ensuring the normal driving of the user and enhancing the safety of the user's driving.

[0064] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vehicle-based risk area reminder device, etc. The following takes a vehicle-based risk area reminder device as an example to illustrate this embodiment and the following embodiments.

[0065] Based on this, the embodiment of the present application provides a risk area reminder method based on a vehicle, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle-based risk area reminder method of the present application.

[0066] In this embodiment, the vehicle-based risk area reminder method includes steps S10 to S40:

[0067] Step S10, obtaining the current latitude and longitude of the target vehicle and the current risk area.

[0068] It is understandable that the latitude and longitude of a vehicle refers to the geographical coordinates of the vehicle's location, which is usually represented by two values: longitude and latitude.

[0069] It should be understood that the current longitude and latitude may be the precise position of the vehicle calculated based on satellite signals using a built-in GPS receiver in the car.

[0070] It should be noted that the current risk area can be obtained by collating real-time emergency and natural disaster data based on the public information interfaces of authoritative official channels and media in each region.

[0071] Step S20, when the target vehicle starts risk reminder, the risk status of the target vehicle is obtained according to the current longitude and latitude and the current risk area.

[0072] It is understandable that a relevant reminder switch for vehicle risk reminder is set on the vehicle computer end, and the function is automatically started when the user actively starts the function, or when certain requirements are met based on pre-settings.

[0073] It should be understood that the longitude and latitude range of the high-risk area can be obtained through the current risk area, and the risk status of the target vehicle can be judged based on whether the current longitude and latitude are within the longitude and latitude range of the current risk area.

[0074] It should be noted that the risk state of the target vehicle may include a far state, an approaching state and an entering state; it is understandable that the far state may mean that the target vehicle is still far away from the current risk area, the approaching state may mean that the straight-line distance between the target vehicle and the target area is less than or equal to a distance threshold, and the entering state may mean that the target vehicle is in the target area.

[0075] Step S30, obtaining risk reminder information according to the risk status.

[0076] It should be noted that the risk warning information includes first-level risk warning information, second-level risk warning information and third-level risk warning information.

[0077] In a feasible implementation, step S31 may include steps A31 to A33:

[0078] Step A11, when the risk state is the remote state, generating first-level risk reminder information.

[0079] It is understandable that there will be corresponding risk warning information when the vehicle is in different risk states.

[0080] It should be noted that the first-level risk reminder may include pushing the housing risk area to the car computer, voice broadcast and pop-up prompts.

[0081] It should be emphasized that the vehicle risk status may also be that there is no risk area. If there is no risk area, no risk reminder will be issued.

[0082] Step A12, when the risk state is a close state, generating secondary risk reminder information.

[0083] It should be noted that the secondary risk reminder information can be a risk area alarm pushed to the vehicle computer, which will emit a buzzer, voice broadcast and pop-up prompt, and at the same time broadcast the straight-line distance between the target vehicle and the risk area at this time, so that users can avoid risks based on this prompt.

[0084] Step A13, when the risk state is the entry state, generate third-level risk reminder information.

[0085] It is understandable that when the risk status is the entry status, the vehicle is already in the risk area. At this time, the third-level risk reminder information needs to be reminded based on the relevant management information of the current risk area. If the management information of the current risk area is to leave as soon as possible, the user is reminded to leave the current risk area as soon as possible, and the management information is sent to the vehicle terminal / user. The vehicle computer buzzes, voice broadcasts, and pops up a prompt; if the management information is to block the area, the user is reminded to pay attention to safety and not to walk around at will. The management information is sent to the vehicle terminal / user, and the vehicle computer buzzes, voice broadcasts, and pops up a prompt.

[0086] In this embodiment, the current risk level of the target vehicle is evaluated by the latitude and longitude of the current vehicle and the distance between the current risk area, and different types of prompt information are given to the vehicle terminal / user based on different risk levels, so that the user can respond to possible risks more quickly, thereby improving the driving safety of the user and the vehicle.

[0087] The above are only feasible implementations of step S30 provided in this embodiment, and this embodiment does not specifically limit the specific implementation of step S30.

[0088] Step S40, sending the risk reminder information to the vehicle end, so that the vehicle end reminds the user of the risk area based on the risk reminder information.

[0089] It should be emphasized that the risk analysis of the target vehicle is based on cloud operations. The cloud obtains the current longitude and latitude of the vehicle sent through T-BOX, and then makes a risk judgment based on the current longitude and latitude of the vehicle.

[0090] It should be understood that the cloud / server can simultaneously provide vehicle risk reminders for the latitude and longitude information fed back by multiple target vehicles.

[0091] In the specific implementation, the implementation logic diagram of the vehicle-based risk area reminder method can be referred to Figure 2In the figure, the vehicle computer periodically reports the vehicle's longitude and latitude information through T-BOX. The cloud (TSP) forms a risk area longitude and latitude set B based on the risk area information obtained periodically, and then generates a risk reminder based on the risk area longitude and latitude set B and the vehicle's current longitude and latitude. Then, according to the MQTT protocol, the risk reminder is sent to the vehicle computer to remind the user.

[0092] In a feasible implementation manner, step S40 may include steps A41 to A44:

[0093] Step A41, when the current risk area is updated, the updated risk area and historical risk status are obtained.

[0094] It is understandable that risk areas are not static. Over time, risk areas may shrink, expand, or disappear. Information on risk areas can be obtained in real time, and users can be alerted to risks based on the latest risk areas.

[0095] It should be understood that the historical risk state may be a target vehicle state obtained based on the historical risk area and the historical latitude and longitude of the vehicle.

[0096] Step A42, obtaining reference risk longitude and latitude according to the updated risk area, and obtaining reference risk status according to the reference risk longitude and latitude.

[0097] It is understandable that the reference risk longitude and latitude can be simply understood as the longitude and latitude of the new risk area after the risk area information is updated.

[0098] It should be understood that the reference risk longitude and latitude are changing, and the longitude and latitude information of the target vehicle is also constantly changing. The reference risk state can be understood as a new risk state obtained based on the reference risk longitude and latitude and the real-time longitude and latitude of the vehicle.

[0099] Step A43: when the historical risk status and the reference risk status are different, new risk reminder information is obtained according to the reference risk status.

[0100] It should be understood that the historical risk state and the reference risk state may or may not be the same.

[0101] It should be noted that if the historical risk status is different from the reference risk status, the risk reminder information for the user will also change, and the corresponding content will also change. The new risk reminder information needs to be sent to the vehicle computer to remind the user.

[0102] It should be emphasized that if the historical risk status is the same as the reference risk status, the level of historical risk reminder is the same and the risk reminder will not be repeated.

[0103] It should be understood that when the risk reminder function on the vehicle side is turned on, if the risk area changes, the real-time risk area can be sent to the vehicle side in real time, which will not be affected by the risk reminder information. The risk reminder information is a reminder of the status of the target vehicle and the risk area.

[0104] Step A44, sending the new risk reminder information to the vehicle side to remind the vehicle side user of the risk area.

[0105] It should be noted that the cloud will send new risk reminder information to the vehicle side, and at the same time save the risk status of the vehicle based on the vehicle identification code of the target vehicle, which will be used to determine whether the risk status has changed the next time the risk area changes.

[0106] In a specific implementation, only the risk status and risk reminder information most recently provided to the vehicle are stored according to the vehicle VIN.

[0107] In this embodiment, by acquiring real-time risk area information, when the risk area changes, the risk status of the target vehicle is evaluated according to the new risk area, and the real-time risk status of the target vehicle can be obtained, thereby providing the target vehicle with more timely and accurate risk reminders, effectively reducing the vehicle driving risk.

[0108] The above are merely feasible implementations after step S40 provided in this embodiment, and this embodiment does not specifically limit the specific implementations after step S40.

[0109] This embodiment provides a vehicle-based risk area reminder method, which accurately determines whether the vehicle is in or close to the risk area by obtaining the vehicle's latitude and longitude information and the current risk area, thereby ensuring the accuracy of subsequent reminders. At the same time, risk reminder information is generated based on the risk status, and based on, by sending the risk reminder information to the vehicle side, the user can receive the risk reminder information in time, and avoid areas with abnormal accidents in time based on the risk reminder information, thereby ensuring the user's normal driving while enhancing the user's driving safety.

[0110] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 , step S20, the vehicle-based risk area reminder method further includes steps S01-S02:

[0111] In this embodiment, the vehicle-based risk area reminder method includes steps S10 to S40:

[0112] Step S21, when the target vehicle starts the risk reminder, the longitude and latitude set of the current risk area is obtained according to the current risk area and the preset area code.

[0113] It should be noted that the preset area code can be an area code that corresponds to each region after encoding each region in the country according to certain rules. The preset area code is composed of a string of numbers, and each preset area code has a corresponding longitude and latitude range. Each district in each city in the country has a unique code.

[0114] It can be understood that the risk area is an area, longitude and latitude are a point, and multiple longitudes and latitudes form a longitude and latitude set, which can form an area.

[0115] It should be understood that the current risk areas obtained by the cloud are urban areas in the conventional sense, such as Haidian District in Beijing and Development Zone in Shenzhen City in Guangdong Province.

[0116] In a feasible implementation manner, before step S21, steps A211 to A213 are also included:

[0117] Step A211, obtaining the division status of each sub-area of ​​the preset target area, and obtaining a longitude and latitude set of the sub-area based on the division status.

[0118] It is understandable that the preset target area may be an area where the target vehicle needs to be reminded. For example, the target area may be global, national, or provincial, and may be determined according to actual needs.

[0119] It should be understood that the preset target area can be further divided to determine the division status of each sub-area in the preset target area. The division status can be understood as the area belonging to each sub-area when the area is divided.

[0120] It should be noted that obtaining the longitude and latitude set of the sub-region based on the division state may be to determine the longitude and latitude of the outermost point of the sub-region according to the area of ​​the sub-region, and to form the longitude and latitude set of the outermost point.

[0121] Step A212: Encode each sub-region to obtain a sub-region code.

[0122] It is understandable that each sub-region has a corresponding name. For example, the code for the sub-region represented by A in District A of City A in Province may be 010101, and the code for the sub-region represented by B in District A of City A in Province may be 010102.

[0123] Step A213, obtaining a preset area code according to the sub-area code and the longitude and latitude set of the sub-area.

[0124] It should be noted that the longitude and latitude sets of each sub-area have been determined in advance. Based on the coding of each area, when assessing the risk status, if the current risk area is A district A in city A in province, the code corresponding to the area is 010101, and the longitude and latitude set corresponding to the current risk area is the longitude and latitude set of the code 010101.

[0125] In this embodiment, the area that needs to be monitored for risks is divided into sub-areas in advance, and each sub-area is encoded, and the longitude and latitude sets of each sub-area are matched with the sub-area codes. When the current risk area is obtained, the longitude and latitude sets of the risk area can be obtained based on the codes corresponding to the risk area, so that the scope of the risk area can be quickly identified, and the risk status of the target vehicle can be accurately assessed, thereby issuing risk alerts to the target vehicle.

[0126] The above are merely feasible implementations before step S21 provided in this embodiment, and this embodiment does not specifically limit the specific implementations before step S21.

[0127] In a feasible implementation, step S21 may include steps A211 to A212:

[0128] Step A211, when the target vehicle starts risk reminder, traverse the preset area code based on the current risk area to obtain the sub-area code.

[0129] It is understandable that the current risk area is matched with each area in the preset area code, and the code corresponding to the area that is successfully matched is the sub-area code.

[0130] Step A212: taking the longitude and latitude set of the sub-area corresponding to the sub-area code as the longitude and latitude set of the current risk area.

[0131] It is understandable that each sub-region code in the preset region code corresponds to the longitude and latitude set of the sub-region, and the longitude and latitude set of the sub-region that successfully matches the current risk region is used as the longitude and latitude set of the current risk region.

[0132] In this implementation, by matching the current risk area with the preset area code, the area corresponding to the current risk area can be quickly located, thereby quickly evaluating the risk status of the target vehicle and issuing a risk reminder.

[0133] The above are only feasible implementations of step S21 provided in this embodiment, and this embodiment does not specifically limit the specific implementation of step S21.

[0134] Step S22, obtaining the risk status of the target vehicle according to the current longitude and latitude and the current risk area longitude and latitude set.

[0135] It should be understood that the current risk area may be one or more, and the risk status between the target vehicle and each risk area is evaluated.

[0136] It should be noted that the risk state includes a distant state, a close state and a dangerous state.

[0137] In a feasible implementation, step S22 may include steps A221 to A222:

[0138] Step A221, obtaining the relative distance between the target vehicle and each current risk area according to the current longitude and latitude and the longitude and latitude set of the current risk area.

[0139] It is understandable that each current risk area longitude and latitude set includes multiple longitudes and latitudes, and obtaining the risk status of the target vehicle based on the current longitude and latitude and the current risk area longitude and latitude set can be to calculate the straight-line distance between the current longitude and latitude and each longitude and latitude in the current risk area longitude and latitude set.

[0140] It should be understood that the distance with the shortest straight-line distance between the current longitude and latitude and the longitude and latitude in the longitude and latitude set of the current risk area is taken as the relative distance between the target vehicle and the current risk area.

[0141] Step A222, obtaining the risk status of the target vehicle according to the relative distance and a preset distance threshold.

[0142] It is understandable that the preset distance threshold may be pre-set, at which the target vehicle can be in a relatively safe state relative to the risk area. The preset distance threshold may be 5 kilometers, or may be set according to actual conditions, which is not limited in this embodiment.

[0143] It should be emphasized that when the relative distance is greater than the preset distance threshold, the distant state is regarded as the risk state of the target vehicle; when the relative distance is less than or equal to the preset distance threshold and greater than 0, the approaching state is regarded as the risk state of the target vehicle; when the relative distance is less than or equal to 0, the dangerous state is regarded as the risk state of the target vehicle.

[0144] In this embodiment, by comparing the preset safety distance (preset distance threshold) with the distance between the target vehicle and the risk area, the risk status of the vehicle can be accurately displayed based on the relative distance.

[0145] It should be emphasized that a reminder is given for each power-on cycle of the target vehicle.

[0146] In specific implementation, after the vehicle computer is started, the "disaster reminder" switch status is on, and there is a risk area, TSP pushes a reminder to the vehicle computer, voice broadcasts and pops up a prompt; after voice or manual clicking of "OK", jumps to the map interface; after voice or manual clicking of "Cancel", there is no page jump; on the map interface, avoid risk areas when setting the navigation destination for route calculation.

[0147] If the destination is not set, the vehicle will be in motion based on the vehicle position reported by T-BOX. When the vehicle is 5 kilometers away from high-risk areas, an epidemic or natural disaster risk alert will be pushed to the vehicle computer, and the vehicle computer will buzz, broadcast a voice message, and pop up a window to prompt.

[0148] After the vehicle is started, T-BOX periodically reports longitude and latitude data to the cloud to obtain risk areas for epidemics and natural disasters in the city where the vehicle is located.
