[0076] ​Those skilled in the art should understand that the terminal device and the server described above are only examples, and other existing or future terminal devices or servers, such as those applicable to the present application, should also be included in the protection scope of the present application and are hereby incorporated by reference.

[0077] The embodiment of the present application provides a rescue method of a vehicle, which can be applied to the implementation environment shown in the above Figure 1 The embodiment of the present application shown in the above Figure 2 The flow chart of the rescue method of the vehicle provided by the embodiment of the present application is taken as an example, which can be executed by the computer device 101 in the above Figure 1 The method includes the following steps 201 to 204, as shown in the above Figure 2

[0078] In step 201, the first driving data sent by the vehicle at the first time is received, and the first driving data includes the first driving speed and the first position information of the vehicle at the first time.

[0079] In a possible implementation, the vehicle is installed with a positioning module and a speed sensor, the positioning module is used to acquire the position information of the vehicle, and the speed sensor is used to acquire the driving speed of the vehicle. During the driving of the vehicle, the positioning module collects the position information of the vehicle every certain time, and the speed sensor collects the driving speed of the vehicle every certain time. The vehicle is also installed with an information communication module (Telematics BOX, TBOX), and after the vehicle collects the first position information of the vehicle at the first time and the first driving speed of the vehicle at the first time, the first driving data of the vehicle at the first time is generated according to the first position information of the vehicle at the first time and the first driving speed of the vehicle at the first time, the first driving data includes the first position information and the first driving speed, and the first driving data is sent to the computer device through the information communication module, so that the computer device acquires the first driving data sent by the vehicle at the first time.

[0080] After the computer device receives the first driving data of the vehicle at the first time, the first driving data of the vehicle at the first time and the first time are stored in the storage space of the computer device, so as to be used subsequently.

[0081] The positioning module collects the position information of the vehicle every certain target time, and the speed sensor collects the driving speed of the vehicle every certain target time. The positioning module and the speed sensor collect at the same time, so that the collected position information and driving speed are at the same time.

[0082] ​Optionally, the target time length is set based on experience, or the target time length is adjusted according to an implementation environment, or the target time length is determined according to a model of the vehicle, and embodiments of the present application do not limit this. For example, the target time length is 2 minutes.

[0083] In step 202, in a case where the second travel data sent by the vehicle is not received at the second time and the first travel speed is greater than the speed threshold, the second position information of the vehicle at the second time is determined according to the first travel speed and the first position information.

[0084] The second time is a time at which the vehicle needs to report travel data after the first time and adjacent to the first time. For example, the vehicle reports travel data to the computer device every reference time length, and the reference time length is the same as the target time length. In this way, after the vehicle collects the travel data, the vehicle directly reports the travel data, so that the reported data has no delay. The second time is a time after the first time, and a time interval between the first time and the second time is the reference time length.

[0085] For example, the vehicle reports travel data to the computer device every 2 minutes, the first time is 16:55, and the second time is 16:57.

[0086] In a possible implementation, the first travel data further includes an identifier of the vehicle. In a case where the second travel data sent by the vehicle is not received at the second time and the first travel speed is greater than the speed threshold, a third travel speed of the vehicle at a third time is obtained according to the identifier of the vehicle, the third time is a time at which the vehicle reports travel data before the first time and adjacent to the first time; and based on a speed difference between the first travel speed and the third travel speed being greater than a difference threshold, the second position information of the vehicle at the second time is determined according to the first travel speed and the first position information.

[0087] The third time is a time before the first time and a time interval between the first time and the third time is the reference time length. The difference threshold is set based on experience, or adjusted according to an implementation environment, and embodiments of the present application do not limit this. For example, the difference threshold is 50. The reason for limiting the speed difference between the first travel speed and the third travel speed is that if the speed of the vehicle suddenly changes during travel, the probability of the vehicle colliding is very high. Therefore, in a case where the speed difference between the first travel speed and the third travel speed is greater than the difference threshold, the vehicle may have collided and needs to be rescued.

[0088] For example, the vehicle reports travel data to the computer device every 2 minutes, the first time is 16:55, and the third time is 16:53.

[0089] Since the probability of collision is relatively large when the vehicle is running at high speed, in the case that the second travel data sent by the vehicle is not received at the second time, the first travel data needs to be acquired first to determine whether the first travel speed is high speed, that is, whether the first travel speed is greater than the speed threshold. Before this, the speed threshold needs to be acquired first, which can be set based on experience or adjusted according to the implementation environment, and the embodiments of the present application do not limit this. Exemplarily, the speed threshold is 80 kilometers / hour.

[0090] Optionally, the speed threshold can also be acquired by the following manner, which includes: determining the first road section where the vehicle is located at the first time according to the first position information; and determining the limit speed of the first road section as the speed threshold.

[0091] In the process of determining the first road section where the vehicle is located at the first time according to the first position information, the computer device can call a map application according to the first position information to determine the road section where the position indicated by the first position information is located, and determine the road section where the position indicated by the first position information is located as the first road section where the vehicle is located at the first time. Optionally, the first position information can be input into the map application to obtain the road section where the position indicated by the first position information is located.

[0092] After the first road section where the vehicle is located at the first time is determined, the process of determining the limit speed of the first road section includes that the computer device stores a corresponding relationship between road section identifiers and limit speeds. The limit speed of the first road section is determined according to the road section identifier of the first road section and the corresponding relationship between road section identifiers and limit speeds. The road section identifier of the first road section can be the name of the first road section, or other identifiers that can uniquely represent the first road section, and the embodiments of the present application do not limit this.

[0093] Optionally, the computer device can further generate a speed acquisition request, the speed acquisition request including the road section identifier of the first road section, and the computer device sends the speed acquisition request to a server. The server stores a corresponding relationship between road section identifiers and limit speeds. The server receives the speed acquisition request, parses the speed acquisition request to obtain the road section identifier of the first road section, determines the limit speed of the first road section according to the road section identifier of the first road section and the corresponding relationship between road section identifiers and limit speeds, and sends the limit speed of the first road section to the computer device to enable the computer device to acquire the limit speed of the first road section.

[0094] In a possible implementation, since the limit speed of a road section is the highest driving data of the road section, when the driving speed of the vehicle is lower than the limit speed of the road section where the vehicle is located, the vehicle will also collide, therefore, the value of the speed threshold can be reduced, so as to reduce the probability that the vehicle is not rescued after the collision. Optionally, after obtaining the limit speed of the first road section, the speed threshold can be determined according to the limit speed of the first road section and the speed percentage, and the speed threshold is lower than the limit speed of the first road section. For example, the product between the limit speed of the first road section and the speed percentage is taken as the speed threshold.

[0095] The speed percentage is set based on experience or adjusted according to the implementation environment, which is not limited in the embodiments of the present application. For example, the speed percentage is 80%.

[0096] For example, the limit speed of the first road section is 80 km / h, and the speed percentage is 80%, and then the speed threshold is 80*80% = 64 km / h.

[0097] In a possible implementation, the process of determining the second position information of the vehicle at the second time according to the first driving speed and the first position information includes: determining a time difference value between the second time and the first time; determining a driving distance according to the time difference value and the first driving speed, the driving distance being a distance driven by the vehicle at the first driving speed for the time difference value; and determining the second position information of the vehicle at the second time according to the first position information and the driving distance.

[0098] The second time is taken as the minuend, the first time is taken as the subtrahend, and the difference between the minuend and the subtrahend is determined as the time difference value.

[0099] The first driving data further includes a driving direction of the vehicle at the first time. The process of determining the second position information of the vehicle at the second time according to the first position information and the driving distance includes: determining a plurality of reference position information according to the first position information and the driving distance, each reference position information indicating a position different from the position indicated by the first position information in direction; and determining the reference position information in the plurality of reference position information, which is in the first driving direction relative to the position indicated by the first position information, as the second position information of the vehicle at the second time.

[0100] In step 203, the second road section where the vehicle is located at the second time is determined according to the second position information.

[0101] In a possible implementation, after the second location information is determined in step 202, a second road section where the vehicle is located at the second time is determined according to the second location information, which is similar to the process of determining a first road section where the vehicle is located at the first time according to the first location information in step 202. For details, refer to the description of step 202, which will not be repeated here.

[0102] In step 204, when the second road section is a highway section, a rescue request is sent to the third-party rescue center, the rescue request including the second location information, and the rescue request is used for the third-party rescue center to rescue the vehicle.

[0103] After the second road section where the vehicle is located at the second time is determined in step 203, it is further determined whether the second road section is a highway section. When the second road section is a highway section, a rescue request is sent to the third-party rescue center, the rescue request including the second location information, and the rescue request is used for the third-party rescue center to rescue the vehicle. Optionally, the rescue request can further include an identifier of the vehicle, and the rescue request is used for the third-party rescue center to rescue the vehicle at the position indicated by the second location information.

[0104] In a possible implementation, the first driving information further includes an identifier of the vehicle. The identifier of the vehicle can be a vehicle identification code (VIN), or can be another identifier that can uniquely represent the vehicle, which is not limited in the embodiments of the present application. The vehicle identification code is a 17-character code, also known as a 17-digit code, which contains information such as the manufacturer, year, model, body style and code, engine code, and assembly location of the vehicle.

[0105] When the second road section is a highway section, the contact information of the driver of the vehicle can also be determined according to the identifier of the vehicle. When the driver cannot be contacted through the contact information, a rescue request is further sent to the third-party rescue center. The driver of the vehicle is contacted to ensure that the vehicle driven by the driver has indeed encountered danger, and then the rescue request is sent to the third-party rescue center, so as to avoid the situation that the third-party rescue center finds that the vehicle has not encountered danger after going to the position indicated by the second location information, and thus the accuracy of rescue can be improved.

[0106] The process of determining the contact information of the driver of the vehicle according to the identifier of the vehicle includes that the computer device stores a correspondence relationship between each identifier and the contact information of the driver corresponding to each identifier, and the contact information of the driver of the vehicle is determined according to the identifier of the vehicle and the correspondence relationship between each identifier and the contact information of the driver corresponding to each identifier.

[0107] In a possible implementation, the computer device can further generate a contact information obtaining request, the contact information obtaining request comprising the identifier of the vehicle, and the computer device sends the contact information obtaining request to a server. The server stores a correspondence between identifiers and contact information of drivers corresponding to the identifiers. The server receives the contact information obtaining request, parses the contact information obtaining request to obtain the identifier of the vehicle, and determines the contact information of the driver of the vehicle according to the identifier of the vehicle and the correspondence between identifiers and contact information of drivers corresponding to the identifiers. The server sends the contact information of the driver of the vehicle to the computer device, so that the computer device obtains the contact information of the driver of the vehicle.

[0108] Optionally, the computer device has a communication function, and after obtaining the contact information of the driver of the vehicle, the computer device calls the communication function to contact the driver of the vehicle according to the contact information of the driver of the vehicle. In the case where the driver of the vehicle is not contacted through the contact information, the computer device sends a rescue request to a third-party rescue center.

[0109] In the case where the driver of the vehicle is contacted through the contact information, the computer device obtains voice data of the driver of the vehicle, converts the voice data to obtain text content corresponding to the voice data, determines safety information corresponding to the text content, and in the case where the safety information indicates that the vehicle is in danger, the computer device sends a rescue request to a third-party rescue center.

[0110] The computer device comprises a voice conversion function, and the voice conversion function is configured to convert voice into text. The process of converting the voice data to obtain the text content corresponding to the voice data comprises: calling the voice conversion function to convert the voice data to obtain the text content corresponding to the voice data.

[0111] The safety information corresponding to the text content comprises vehicle safety and vehicle danger. After obtaining the text content corresponding to the voice data, the computer device inputs the text content into a safety information determination model, and takes the output of the safety information determination model as the safety information corresponding to the text content. The safety information determination model can be any model that can determine safety information, and the embodiments of the present application do not limit the safety information determination model.

[0112] Optionally, after obtaining the text content corresponding to the voice data, a text feature vector used for representing the text content is determined; a first feature vector used for representing vehicle safety is determined, and a second feature vector used for representing vehicle danger is determined. According to the text feature vector and the first feature vector, a first matching degree between the text content and the vehicle safety is determined; according to the text feature vector and the second feature vector, a second matching degree between the text content and the vehicle danger is determined. In a case where the first matching degree is greater than the second matching degree, the safety information corresponding to the text content is determined as the vehicle safety. In a case where the first matching degree is less than the second matching degree, the safety information corresponding to the text content is determined as the vehicle danger.

[0113] The process of determining the text feature vector used for representing the text content, the process of determining the first feature vector used for representing the vehicle safety, and the process of determining the second feature vector used for representing the vehicle danger are similar, and only the process of determining the text feature vector used for representing the text content is taken as an example for description. Optionally, the process of determining the text feature vector used for representing the text content includes: inputting the text content into a feature vector determination model, and taking content output by the feature vector determination model as the text feature vector. The feature vector determination model can be any model capable of determining a feature vector, and the embodiments of the present application do not limit the feature vector determination model. Exemplarily, the feature vector determination model is a Long Short-Term Memory (LSTM) model.

[0114] It should be noted that, in a case where the safety information indicates the vehicle safety, it means that the vehicle does not need to be rescued, and thus a rescue request does not need to be sent to the third-party rescue center.

[0115] In a possible implementation, the process of sending the rescue request to the third-party rescue center includes: sending the rescue request to a terminal device corresponding to the third-party rescue center, so that the terminal device corresponding to the third-party rescue center receives the rescue request, analyzes the rescue request, obtains the second location information, displays the second location information, and then makes the staff of the third-party rescue center go to the position indicated by the second location information to rescue the vehicle.

[0116] Optionally, a rescue route can also be planned for the staff of the third-party rescue center according to the position of the third-party rescue center and the second location information, the starting point of the rescue route is the position of the third-party rescue center, and the key point is the position indicated by the second location information. The rescue route is sent to the terminal device of the third-party rescue center, so that the staff of the third-party rescue center go to the position indicated by the second location information according to the rescue route.

[0117] In a possible implementation, according to the location of the third-party rescue center and the second location information, a plurality of candidate routes are determined, and a time length corresponding to each candidate route is determined; a candidate route with the least time length in the plurality of candidate routes is determined as the rescue route, so that the staff of the third-party rescue center can arrive at the location indicated by the second location information as soon as possible, and rescue the vehicle as soon as possible, so as to reduce the probability of danger.

[0118] In the above method, if the first driving speed of the vehicle at the first time is greater than the speed threshold, that is, the vehicle is driving at a high speed, and the second driving data of the vehicle at the second time is not received, the second location information of the vehicle at the second time is determined according to the first driving data of the vehicle. Since the vehicle is more likely to collide when driving at a high speed, the second location information of the vehicle at the second time is determined according to the first driving data of the vehicle. Since the probability of collision of the vehicle when driving on the highway is relatively high, in the case where it is determined that the vehicle is located on the highway section at the second time, the rescue request is sent to the rescue center, so that the vehicle can be rescued in time, the rescue efficiency is improved, and the driving safety of the vehicle is improved.

[0125] The determining module 302 is configured to, in a case where the second travel data transmitted by the vehicle is not received at the second time and the first travel speed is greater than the speed threshold, acquire, according to the identifier of the vehicle, a third travel speed of the vehicle at a third time, the third time being a time at which the vehicle reports travel data before and adjacent to the first time; and determine, according to the first travel speed and the first position information, the second position information of the vehicle at the second time based on a speed difference between the first travel speed and the third travel speed being greater than a difference threshold.

[0126] In a possible implementation, the determining module 302 is further configured to determine, according to the first position information, a first road section on which the vehicle is located at the first time; and determine the speed threshold as a limit speed of the first road section.

[0127] In a possible implementation, the determining module 302 is configured to determine a time difference between the second time and the first time; determine a travel distance according to the time difference and the first travel speed; and determine the second position information of the vehicle at the second time according to the first position information and the travel distance.

[0128] In a possible implementation, the first travel data further includes a first travel direction of the vehicle at the first time.

[0129] The determining module 302 is configured to determine, according to the first position information and the travel distance, a plurality of reference position information, each reference position information indicating a position different from the position indicated by the first position information in a direction; and determine, as the second position information of the vehicle at the second time, reference position information in the plurality of reference position information that is in the first travel direction relative to the position indicated by the first position information.

[0130] In a possible implementation, the first travel information further includes an identifier of the vehicle.

[0131] The determining module 302 is further configured to, in a case where the second road section is a highway section, determine, according to the identifier of the vehicle, a contact manner of a driver of the vehicle.

[0132] The sending module 303 is configured to, in a case where the driver is not contacted through the contact manner, send a rescue request to a third-party rescue center.

[0133] In a possible implementation, the apparatus further includes:

[0134] The acquiring module is configured to, in a case where the driver is contacted through the contact manner, acquire voice data of the driver.

[0137] The sending module 303 is further configured to send a rescue request to a third-party rescue center in a case where the safety information indicates that the vehicle is in danger.

[0138] In a case where the device does not receive the second driving data reported by the vehicle at the second time, if the first driving speed of the vehicle at the first time is greater than the speed threshold, that is, the vehicle is driving at a high speed, the second position information of the vehicle at the second time is determined according to the first driving data of the vehicle, because the vehicle is prone to collision when driving at a high speed. Since the probability of collision when the vehicle is driving on the highway is relatively high, in a case where it is determined that the vehicle is located on the highway section at the second time, a rescue request is sent to the rescue center, so that the vehicle can be rescued in time, the rescue efficiency is improved, and the driving safety of the vehicle is improved.
