In this way, the scope of vehicle search can be expanded, thereby increasing the success rate of vehicle search. And this method can also be used in areas where the cellular network is not covered (or the usage experience is poor), so it helps to increase the success rate of vehicle search in these scenarios.

[0106] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0107] Before introducing the method, device, terminal, vehicle, and storage medium for determining a vehicle position according to the present disclosure, an exemplary introduction to the application scenario of the embodiments of the present disclosure will be given first.

[0108] When a user uses a vehicle, the vehicle's location can be determined through the vehicle finding function. For example, in some scenarios, the user can open the car App (application) in the terminal and click to activate the vehicle finding function. Figure 1 is a schematic diagram of a vehicle finding scenario shown in an exemplary embodiment of the present disclosure. Refer to Figure 1 , when finding a vehicle, the terminal 200 can connect to the user's vehicle 600 through near-field communication (such as Bluetooth, radio frequency, etc.) and send a vehicle finding instruction to the user's vehicle 600. After that, the user's vehicle 600 can give feedback on the vehicle finding instruction, and the feedback method can be honking or flashing lights. However, the applicable distance of near-field communication is relatively short, and when the distance between the user terminal 200 and the user's vehicle 600 is relatively far, the phenomenon of vehicle finding failure may occur.

[0109] In some scenarios, the terminal can connect to the vehicle through remote communication (such as a cellular network) and send a vehicle finding instruction to the vehicle. After that, the vehicle can give feedback on the vehicle finding instruction, thereby realizing the vehicle finding function. However, in scenarios such as underground parking lots, the cellular network may not be fully covered, so the phenomenon of vehicle finding failure is also likely to occur.

[0110] For this reason, the embodiments of the present disclosure provide a method for determining the location of a vehicle, which is applied to a terminal. The terminal can be, for example, a mobile phone, a tablet device, etc. Figure 2 is a flowchart of a method for determining the location of a vehicle shown in an exemplary embodiment of the present disclosure, as Figure 2 shown, the method includes:

[0111] In step S21, a first request is generated, and the first request includes the identifier of the target vehicle.

[0112] For example, in a possible implementation manner, the generating of the first request includes:

[0113] Taking the target vehicle as the recipient, sending a vehicle finding instruction, and the vehicle finding instruction is used to determine the location of the target vehicle;

[0114] In the case where the response to the vehicle finding instruction is abnormal, the first request is generated.

[0115] Exemplarily, the terminal can respond to the user's vehicle finding operation and send a vehicle finding instruction with the target vehicle as the recipient. If the response to the vehicle finding instruction is abnormal, the first request can be generated, thereby starting an auxiliary vehicle finding process based on other vehicles.

[0116] One or more rules can be set to determine whether the response to the car-finding instruction is abnormal. For example, in one implementation, it can be determined that the response to the car-finding instruction is abnormal when the car-finding instruction fails to be sent. In one implementation, if a response message to the car-finding instruction is not received within a duration threshold, it can be determined that the response to the car-finding instruction is abnormal.

[0117] In step S22, a first request is broadcast within the broadcast domain of the terminal. The first request is used for a first vehicle to determine whether it is the target vehicle. The first vehicle is the vehicle that receives the first request.

[0118] In one implementation, the terminal and the vehicle can communicate based on Bluetooth. Therefore, the broadcast domain can refer to the Bluetooth broadcast domain.

[0119] In one implementation, the terminal and the vehicle can communicate based on WIFI (Wireless Fidelity). Therefore, the broadcast domain can refer to the WIFI broadcast domain.

[0120] The terminal broadcasts the first request within the broadcast domain. The vehicle that receives the first request within the broadcast domain can respond to the first request. For example, the vehicle that receives the first request can be used as the first vehicle. The first vehicle can respond to the first request and determine whether it is the target vehicle. As an example, the first vehicle can compare its vehicle identifier with the identifier of the target vehicle in the first request to determine whether it is the target vehicle.

[0121] When the first vehicle is not the target vehicle, the first vehicle can broadcast the first request within the broadcast domain of the first vehicle. In this way, the vehicle that receives the first request within the broadcast domain of the first vehicle can be used as the new first vehicle and respond to the first request.

[0122] Figure 3 is a schematic diagram of a car-finding scenario shown in an exemplary embodiment of the present disclosure. Refer to Figure 3 , if the identifier of the target vehicle is D, the terminal 200 can broadcast a first request including the identifier D within the broadcast domain of the terminal 200. In this way, the vehicle A within the broadcast domain of the terminal 200 can receive the first request and be used as the first vehicle. The vehicle A can compare its vehicle identifier with the identifier D of the target vehicle. When its vehicle identifier is inconsistent with the identifier D of the target vehicle, it can determine that it is not the target vehicle. Refer to Figure 3, Vehicle A can continue to broadcast the first request within its own broadcast domain. In this way, Vehicles B and C that receive the first request in the broadcast domain of Vehicle A can serve as new first vehicles and respond to the first request respectively. Taking Vehicle C as an example, when Vehicle C determines that it is not the target vehicle, it can broadcast the first request within the broadcast domain of Vehicle C. In this way, Vehicles D and E that receive the first request in the broadcast domain of Vehicle C can serve as new first vehicles and respond to the first request respectively to determine whether they are the target vehicle.

[0123] In Figure 3 's example, Vehicle D can respond to the first request and determine that it is the target vehicle.

[0124] When the first vehicle is the target vehicle, the first vehicle can send a response message of the first request to the sender of the first request. It should be noted that the first request received by the first vehicle may come from a terminal or other vehicles. For example, in Figure 3 's example, the first request received by Vehicle D is broadcast and sent by Vehicle C, so Vehicle D can send the response message to Vehicle C.

[0125] In addition, in the case where the first vehicle receives a response message of the first request sent by other vehicles, it can send the response message to the sender of the first request. For example, in Figure 3 's example, after Vehicle C receives the response message sent by Vehicle D, it can send the response message to Vehicle A. After Vehicle A receives the response message, it can send the response message to the sender of the first request received by Vehicle A, that is, send it to Terminal 200.

[0126] Referring to Figure 2 , in step S23, determine the position of the target vehicle according to the received response message of the first request.

[0127] For example, in a possible implementation manner, determining the position of the target vehicle according to the received response message of the first request includes:

[0128] Generate a route from the terminal position to the target vehicle according to the position information of the terminal and the position information of the target vehicle in the response message;

[0129] Display the route on the display interface of the terminal.

[0130] That is to say, the terminal can obtain the position information of the target vehicle according to the response message, and generate a route from the terminal position to the target vehicle according to the position information of the terminal and the position information of the target vehicle. The terminal can also display the route on the display interface of the terminal, so as to assist the user in finding the target vehicle based on the route. In this way, the efficiency of the user finding the vehicle can be improved.

[0131] In some embodiments, the terminal may also obtain the location information of the target vehicle according to the response message and display the location information of the target vehicle on the map of the terminal.

[0132] With the above solution, the terminal can use other vehicles to assist in finding the location of the target vehicle. In this way, the scope of vehicle search can be expanded, thereby increasing the success rate of vehicle search. Moreover, this method can also be used in areas where the cellular network is not covered (or the usage experience is poor), so it helps to increase the success rate of vehicle search in these scenarios.

[0133] In some scenarios, an authentication and filtering process can also be set for the communication between the terminal and the vehicle.

[0134] For example, in a possible embodiment, a first request is broadcast within the broadcast domain of the terminal, including:

[0135] Determine a second vehicle located within the broadcast domain of the terminal;

[0136] Negotiate a key with the second vehicle to obtain a first key;

[0137] Generate first authentication information according to the first key;

[0138] Taking the second vehicle as the recipient, broadcast the first request and the first authentication information within the broadcast domain of the terminal. The first authentication information and the first key are used for the second vehicle to authenticate the first request. Among them, the first vehicle includes the second vehicle that successfully receives the first request. When the first request is authenticated successfully, the second vehicle responds to the first request.

[0139] As an example, the determining of the second vehicle located within the broadcast domain of the terminal includes:

[0140] The terminal broadcasts a second request within the broadcast domain of the terminal, and the second request is used to determine the vehicle that can be used to assist in searching for the vehicle. In this way, the terminal can determine the second vehicle according to the response message of the second request.

[0141] For example, in an embodiment, the terminal can determine whether the vehicle supports the function of assisting in searching for the vehicle according to the fields in the response message of the second request. For example, 1 indicates supporting the function of assisting in searching for the vehicle, and 0 indicates not supporting the function of assisting in searching for the vehicle. These fields can be defined and set based on requirements, and the embodiments of the present disclosure do not limit this.

[0142] In an embodiment, the vehicle sending a response message to the terminal can indicate that the vehicle supports the function of assisting in searching for the vehicle.

[0143] Through the response message, the terminal can determine a second vehicle that supports the function of assisting in searching for a vehicle. The terminal can also perform key negotiation with the second vehicle to obtain a first key.

[0144] In some embodiments, the first keys negotiated by the terminal with multiple second vehicles can be the same, that is, the same key is used between the terminal and multiple vehicles.

[0145] In some embodiments, the terminal can negotiate different first keys with each second vehicle respectively, that is, different keys are used between the terminal and different vehicles.

[0146] After determining the first key, the terminal can generate first verification information based on the first key, and broadcast the first request and the first verification information within the broadcast domain of the terminal with the second vehicle as the recipient. The first verification information and the first key are used for the second vehicle to verify the first request, where the first vehicle includes the second vehicle that successfully receives the first request. In the case where the first request is verified successfully, the second vehicle responds to the first request.

[0147] In one implementation manner, the first verification information and the first request can be sent in a package, and the first verification information can be used to verify whether the first request is credible.

[0148] In one implementation manner, for example, the first verification information can be generated based on a random number obtained from the second vehicle. The terminal can encrypt the random number with the first key negotiated with the second vehicle to obtain the first verification information. In this way, the second vehicle that receives the first request can decrypt the first verification information with the first key negotiated with the terminal in advance. When the decrypted random number is consistent with the random number provided by itself, it is determined that the first verification information and the first request are sent by the terminal, so the first request is considered credible. When the decryption fails, or the decrypted random number is inconsistent with the random number provided by itself, it is determined that the first request is not credible and the response to the first request is refused.

[0149] In this way, the security of communication can be improved, and the effect of filtering requests can be achieved.

[0150] Based on the same inventive concept, the present disclosure also provides a method for determining a vehicle position, which is applied to a first vehicle. The first vehicle can be the first vehicle involved in the above embodiments. Figure 4 is a flowchart of a method for determining a vehicle position shown in an exemplary embodiment of the present disclosure. Referring to Figure 4 , the method includes:

[0151] In step S41, a first request is received. The first request is generated by a terminal and includes an identifier of a target vehicle. The first request is used by a first vehicle to determine whether it is the target vehicle.

[0152] In step S42, when the first vehicle is not the target vehicle, the first request is broadcast within the broadcast domain of the first vehicle.

[0153] In step S43, when the first vehicle is the target vehicle, or when the first vehicle receives a response message of the first request sent by another vehicle, a response message of the first request is sent to the sender of the first request. The response message includes the location information of the target vehicle, and the response message is used by the terminal to determine the location of the target vehicle.

[0154] Referring to Figure 3 , if the identifier of the target vehicle is D, the terminal 200 can broadcast a first request including the identifier D within the broadcast domain of the terminal 200. In this way, vehicle A within the broadcast domain of the terminal 200 can receive the first request and act as the first vehicle. Vehicle A can compare its own vehicle identifier with the identifier D of the target vehicle. When its own vehicle identifier is inconsistent with the identifier D of the target vehicle, it can determine that it is not the target vehicle. Referring to Figure 3 , vehicle A can continue to broadcast the first request within its own broadcast domain. In this way, vehicle B and vehicle C that receive the first request within the broadcast domain of vehicle A can act as new first vehicles and respond to the first request respectively. Taking vehicle C as an example, when vehicle C determines that it is not the target vehicle, it can broadcast the first request within the broadcast domain of vehicle C. In this way, vehicle D and vehicle E that receive the first request within the broadcast domain of vehicle C can act as new first vehicles and respond to the first request respectively to determine whether they are the target vehicle.

[0155] In Figure 3 's example, vehicle D can respond to the first request and determine that it is the target vehicle.

[0156] When the first vehicle is the target vehicle, the first vehicle can send a response message of the first request to the sender of the first request. It should be noted that the first request received by the first vehicle may come from the terminal or from other vehicles. For example, in Figure 3 's example, the first request received by vehicle D is broadcast and sent by vehicle C, so vehicle D can send the response message to vehicle C.

[0157] In addition, when the first vehicle receives a response message of the first request sent by another vehicle, it can send the response message to the sender of the first request. For example, in Figure 3In the example, after vehicle C receives the response message sent by vehicle D, it can send the response message to vehicle A. After vehicle A receives the response message, it can send the response message to the sender of the first request received by vehicle A, that is, to terminal 200. In this way, terminal 200 can determine the location of the target vehicle according to the response message.

[0158] By adopting the above solution, the terminal can use other vehicles to assist in finding the location of the target vehicle. In this way, the scope of vehicle search can be expanded, thereby increasing the success rate of vehicle search. Moreover, this method can also be used in areas where the cellular network is not covered (or the usage experience is poor), so it helps to increase the success rate of vehicle search in these scenarios.

[0159] In a possible implementation manner, based on Figure 4 the above, the method includes:

[0160] Conduct key negotiation with the sender of the first request to obtain a second key;

[0161] The receiving of the first request includes:

[0162] Receive the first request broadcast by the sender and second verification information, where the second verification information is generated by the sender according to the second key;

[0163] The method further includes:

[0164] Verify the first request according to the second key and the second verification information;

[0165] In the case where the verification passes, in response to the first request, determine whether itself is the target vehicle.

[0166] It should be noted that the first request received by the first vehicle may come from the terminal or other vehicles. Therefore, the sender can be the terminal or other vehicles. The sender can negotiate with the first vehicle to obtain a second key and generate second verification information according to the second key.

[0167] In one embodiment, the second verification information can be generated based on, for example, a randomly generated number obtained from the first vehicle. The sender can encrypt the random number with a second key negotiated with the first vehicle to obtain the second verification information. In this way, the first vehicle that receives the first request can decrypt the second verification information with the second key negotiated. When the decrypted random number is consistent with the random number provided by itself, it is determined that the second verification information and the first request are sent by the sender, and thus the first request is considered credible. When the decryption fails, or the decrypted random number is inconsistent with the random number provided by itself, it is determined that the first request is not credible, and the response to the first request is rejected.

[0168] In this way, the security of communication can be improved, and the effect of filtering requests can be achieved.

[0169] In one possible embodiment, the broadcasting of the first request within the broadcast domain of the first vehicle includes:

[0170] Determine a third vehicle located within the broadcast domain of the first vehicle;

[0171] Negotiate a key with the third vehicle to obtain a third key;

[0172] Generate third verification information based on the third key;

[0173] Broadcast the first request and the third verification information within the broadcast domain of the first vehicle. The third verification information is used for the third vehicle to verify the first request. Among them, the first vehicle includes the third vehicle that successfully receives the first request. When the first request is verified, the third vehicle responds to the first request.

[0174] As an example, the determining of the third vehicle located within the broadcast domain of the first vehicle includes:

[0175] Broadcast a third request within the broadcast domain of the first vehicle. The third request is used to determine the vehicle that can be used to assist in searching for vehicles;

[0176] Determine the third vehicle according to the response message of the third request.

[0177] For example, in one embodiment, it can be determined whether the vehicle supports the function of assisting in searching for vehicles according to the fields in the response message of the third request. For example, 1 indicates support for the function of assisting in searching for vehicles, and 0 indicates no support for the function of assisting in searching for vehicles. These fields can be defined and set based on requirements, and the embodiments of the present disclosure do not limit this.

[0178] The first vehicle can determine a third vehicle that supports the function of assisting in searching for vehicles through the response message. The terminal can also negotiate a key with the third vehicle to obtain a third key.

[0179] In some embodiments, the third keys negotiated by the first vehicle with multiple third vehicles can be the same, that is, the same key is used between the first vehicle and multiple third vehicles.

[0180] In some embodiments, the first vehicle can negotiate different third keys with each third vehicle respectively, that is, different keys are used between the first vehicle and different third vehicles.

[0181] After determining the third key, the first vehicle can generate third verification information based on the third key, and broadcast the first request and the third verification information within the broadcast domain of the first vehicle with the third vehicle as the recipient. The third verification information and the third key are used for the third vehicle to verify the first request. Among them, the first vehicle includes the third vehicle that successfully receives the first request. When the first request is verified to be passed, the third vehicle responds to the first request.

[0182] In one implementation manner, the third verification information and the first request can be packaged and sent, and the third verification information can be used to verify whether the first request is trustworthy.

[0183] In one implementation manner, for example, the third verification information can be generated based on a random number obtained from the third vehicle. The first vehicle can encrypt the random number with the first key negotiated with the third vehicle to obtain the third verification information. In this way, the third vehicle that receives the first request can decrypt the third verification information with the third key. When the decrypted random number is consistent with the random number provided by itself, it is determined that the third verification information and the first request are sent by the first vehicle, so the first request is considered trustworthy. When the decryption fails, or the decrypted random number is inconsistent with the random number provided by itself, it is determined that the first request is not trustworthy and the response to the first request is refused.

[0184] In this way, the security of communication can be improved, and the effect of filtering requests can be achieved.

[0185] In one possible implementation manner, the method includes:

[0186] In response to the user's selection, turn on or off the function of the first vehicle to assist in searching for vehicles;

[0187] Among them, when the function of assisting in searching for vehicles is turned off, the first vehicle refuses to respond to the first request.

[0188] Exemplarily, a graphical control can be set in the vehicle APP. When the user clicks on the graphical control, the function of assisting in searching for the vehicle of the first vehicle can be turned on or off based on the user's selection. In this way, the controllability of the vehicle can be improved, and the user can choose to turn off the function of assisting in searching for the vehicle, thereby reducing the energy consumption of the vehicle.

[0189] In some embodiments, the vehicle includes a communication master node and a plurality of communication slave nodes. Taking Bluetooth as an example, it can include one Bluetooth master node and a plurality of Bluetooth slave nodes. The first vehicle is further configured to wake up the plurality of slave nodes when receiving a first request and / or a response message of the first request sent by other vehicles; and to put the plurality of slave nodes into sleep when no new first request and / or no new response message of the first request sent by other vehicles is received within a preset time period. In this way, by setting the sleep strategy of the slave nodes, the response delay and the vehicle energy consumption can be reduced.

[0190] Figure 5 is a flowchart of a method for determining a vehicle position shown in an exemplary embodiment of the present disclosure. Referring to Figure 5 , the method includes:

[0191] In response to the user's vehicle search operation, the mobile phone sends a vehicle search instruction to the target vehicle. In the case where the vehicle search instruction is not responded to, it is determined that the vehicle search fails, and a vehicle search broadcast field is broadcast in the broadcast domain of the mobile phone, and the vehicle search broadcast field is used to determine the vehicles that can be used to assist in vehicle search.

[0192] After receiving the vehicle search broadcast field, Vehicle 2 sends a feedback message of the vehicle search broadcast field to the mobile phone, and the feedback message can include, for example, the identifier of Vehicle 2.

[0193] The mobile phone can broadcast an auxiliary vehicle search request based on the identifier of Vehicle 2, and the auxiliary vehicle search request can include the identifier of the target vehicle. Vehicle 2 can receive the auxiliary vehicle search request after a filtering operation, and broadcast the vehicle search request in the broadcast domain of Vehicle 2.

[0194] Referring to Figure 5 , Vehicle 1 can receive the vehicle search request of Vehicle 2 and broadcast the vehicle search request in the broadcast domain of Vehicle 1. Vehicle n can receive the vehicle search request of Vehicle 1 and broadcast the vehicle search request in the broadcast domain of Vehicle n.

[0195] In this way, the target vehicle can receive the vehicle search request and feedback its own positioning information. The positioning information can also refer to the relevant information required for positioning. Referring to Figure 5, the target vehicle can feedback the information required for positioning to Vehicle n. Vehicle n then feedbacks the information required for positioning and the positioning result of the target vehicle to Vehicle 1. Vehicle 1 further feedbacks the information required for positioning and the positioning result of the target vehicle to Vehicle 2, and Vehicle 2 sends them to the mobile phone. In this way, the mobile phone can receive the positioning information jointly determined by multiple vehicles, and based on this information and the direction angle of the mobile phone's gyroscope, describe the relative position relationship between the mobile phone and the target vehicle. The mobile phone can also display this relative position relationship in the car APP to assist the user in finding the target vehicle.

[0196] With the above solution, the terminal can use other vehicles to assist in finding the position of the target vehicle. In this way, the search scope of the vehicle can be expanded, thereby increasing the success rate of vehicle search. Moreover, this method can also be used in areas where the cellular network is not covered (or the usage experience is poor), which helps to increase the success rate of vehicle search in these scenarios.
