[0023] In conjunction with the accompanying drawings, a method and system for finding and positioning a vehicle provided by an embodiment of the present invention will be described in detail through specific embodiments and application scenarios.

[0024] With the development of intelligent technology, automotive electronics are constantly innovating, and the form of car keys is also constantly changing. From the mechanical keys in the first stage, the keys in the second stage, to the digital keys in the current stage, car keys are becoming more and more convenient. At present, smart cars can be equipped with car digital keys, NFC card keys, etc., and the frequency of use of traditional remote control keys is gradually decreasing. However, before the car is assembled and shipped out of the factory, because the remote control key is cancelled, it is necessary to use the equipped mechanical key or NFC card key to control the car, but the mechanical key or NFC card needs to be close to the vehicle to perform unlocking and other controls on the vehicle. Therefore, after the remote control key is cancelled, when you need to find the vehicle, because the mechanical key or NFC card needs to be close to the vehicle to perform unlocking and other controls on the vehicle, it will be extremely difficult to find the car, which seriously affects the efficiency of personnel finding and moving the car.

[0025] The embodiment of the present invention can avoid abuse of permissions and systems by setting corresponding vehicle search permissions through application information, and all vehicle control instructions are end-to-end encrypted to ensure the security of operations.

[0026] Reference Figure 1 , shows a cloud service end step flow chart of a vehicle location method embodiment of the present invention, which may specifically include the following steps: Step 101, obtaining account application information from the account application terminal; In the embodiment of the present invention, the account application information sent by the user at the account application terminal can be obtained from the account application terminal, and the application information at least includes the employment status of the account applicant and the usage type of the account. After the account application terminal approves, the cloud service obtains the corresponding account application information from the account application terminal. Among them, the account application terminal can be an OA system (Office Automation System) or other office systems, and the embodiment of the present invention does not limit the system of the account application terminal.

[0027] Step 102, setting the car search authority corresponding to the account according to the application information; In the embodiment of the present invention, the cloud service end can set the vehicle search permission of the corresponding account according to the obtained account application information, and the vehicle search permission will be updated as the application information of the account changes.

[0028] Specifically, the cloud service end can obtain the applicant's employment status and / or the account usage type in real time based on the account application end. When the applicant's employment status and / or the account usage type of the account changes, the car search permission corresponding to the account will also change accordingly. By dynamically updating the car search permission based on the application information, strict permission control can be performed on the users. Once an employee leaves or the employment status changes, the account will be automatically disabled.

[0029] Step 103, obtaining the vehicle identification number of the target vehicle to be queried by the current account of the client, and performing an authority check on the vehicle search authority of the current account of the client based on the vehicle identification number. If the authority check passes, a location information request of the target vehicle corresponding to the vehicle identification number is sent to the vehicle terminal, so that the vehicle terminal sends the location information of the target vehicle to the cloud service end according to the location information request; In an embodiment of the present invention, the cloud server can obtain the vehicle identification number of the target vehicle to be queried by the current account of the client, judge the vehicle status based on the VIN code (Vehicle Identification Number), and judge whether the vehicle search permission of the current account of the client can pass the permission verification based on the vehicle status of the target vehicle, that is, judge whether the account can query the location information of the vehicle and / or control the target vehicle. Only after passing the permission verification, the cloud server will send the positioning information request of the target vehicle to the vehicle-mounted terminal, so that the vehicle-mounted terminal sends the positioning information of the target vehicle to the cloud server according to the positioning information request.

[0030] Step 104, sending the positioning information of the target vehicle to the client, and upon receiving the encrypted vehicle search instruction sent by the client, performing a secondary permission check on the vehicle search permission of the client's current account based on the vehicle identification number, and if the secondary permission check passes, transmitting the vehicle search instruction to the vehicle terminal, so that the vehicle terminal performs a certificate check on the vehicle search instruction based on the vehicle search instruction, and executing the vehicle search instruction if the certificate check passes.

[0031] In an embodiment of the present invention, after the cloud server sends the positioning information of the target vehicle to the client, it will also obtain the encrypted vehicle search instruction issued by the client based on the target vehicle. After receiving the encrypted vehicle search instruction sent by the client, the vehicle search permission of the current account will be secondary verified based on the VIN code. Only after the secondary permission verification, the cloud server will transmit the vehicle search instruction to the vehicle-mounted terminal, so that the vehicle-mounted terminal will perform a certificate verification on the vehicle search instruction based on the vehicle search instruction. If the certificate verification passes, the vehicle search instruction is executed, wherein the vehicle search instruction is signed by the certificate private key, and the terminal verifies the signature of the received signed instruction.

[0032] A method for finding and locating a vehicle provided by an embodiment of the present invention obtains application information of an account from an account application terminal; sets corresponding vehicle finding permissions according to the application information, obtains the vehicle identification number of a target vehicle queried by the current account, performs permission verification on the vehicle finding permission of the current account based on the vehicle identification number, and if the permission verification passes, obtains the positioning information of the target vehicle through an on-board terminal. If an encrypted vehicle finding instruction is received, a secondary permission verification is performed on the vehicle finding permission of the current account of the client based on the vehicle identification number. If the verification passes, the vehicle finding instruction is transmitted to the on-board terminal, so that the on-board terminal performs a certificate verification on the vehicle finding instruction. If the certificate verification passes, the vehicle finding instruction is executed. Setting corresponding vehicle finding permissions through application information can avoid abuse of permissions and systems, and all vehicle control instructions are end-to-end encrypted to ensure the security of operations.

[0033] In one embodiment of the present invention, the vehicle search authority at least includes: a first vehicle search authority, a second vehicle search authority, and no vehicle search authority; The setting of the vehicle search authority corresponding to the account based on the application information includes: If the person information of the application information meets the application conditions and the usage type of the application information is used within a preset range, the account has the first car search permission; If the person information of the application information meets the application conditions and the usage type of the application information is outside the preset scope, the account has the second car search permission; If the personal information of the application information does not meet the application requirements, the account will not have the authority to search for the vehicle.

[0034] In an embodiment of the present invention, the vehicle search permission can be divided into at least a first vehicle search permission, a second vehicle search permission, and no vehicle search permission, and different application information corresponds to different vehicle search permissions. In one embodiment, it can be set that when the job status of the account applicant is in-service status and the usage type is use within a preset range, the account has the first vehicle search permission, and can obtain the positioning information of the target vehicle within the preset range and / or control the target vehicle; when the position status of the account applicant is in-service status and the usage type is use outside the preset range, the account has the second vehicle search permission, and can obtain the positioning information of the target vehicle outside the preset range; when the position status of the account applicant is resigned status, the account has no vehicle search permission, and cannot obtain the positioning information of the target vehicle and / or control the target vehicle, wherein the preset range can be the area of ​​the factory parking lot, or it can be a specific area responsible for parking the vehicle after it is offline, and it can be set according to the specific usage situation. The embodiment of the present invention does not limit the preset range.

[0035] By limiting the account access rights based on the applicant's position status and usage type, strict permission control is implemented on users to avoid privacy leaks due to the ability to view the vehicle's location information and control the vehicle when the applicant's application information does not meet the requirements.

[0036] In one embodiment of the present invention, before obtaining the vehicle identification number of the target vehicle to be queried by the current account of the client, the method further includes: When the remote control certificate application instruction sent by the client is obtained, the remote control certificate is generated and sent to the client.

[0037] In an embodiment of the present invention, before the cloud server obtains the vehicle identification number of the target vehicle to be queried by the client's current account, it will also generate a remote control certificate and send it to the client when obtaining the remote control certificate application instruction sent by the client. Specifically, a pair of public and private keys can be generated by the client. The public key will be used to generate a CSR (Certificate Signing Request) file, and the private key will be used for subsequent signature operations. After the public-private key pair is generated, the public key needs to be assembled into a CSR file. The CSR file contains the public key, user information and signature. After the CSR file is generated, it is sent to the cloud server.

[0038] When the client logs in to the account, it will determine whether the account has the permission to search for the car. If it has the permission to search for the car, it will determine whether it has a remote control certificate. If it does not, it will generate a remote control certificate application instruction and send it to the cloud server. The cloud server will generate a remote control certificate based on the remote control certificate application instruction and send it to the client. By sending the remote control certificate, all vehicle control instructions are end-to-end encrypted to ensure the security of the instructions.

[0039] In one embodiment of the present invention, the cloud service end includes at least: an Internet of Vehicles service platform and a certificate management platform; The step of generating the remote control certificate and sending it to the client upon obtaining the remote control certificate application instruction sent by the client comprises: When the Internet of Vehicles service platform receives the remote control certificate application instruction sent by the client, the remote control certificate application instruction is transmitted to the certificate management platform; The certificate management platform generates a remote control certificate and sends it to the Internet of Vehicles service platform; The Internet of Vehicles service platform sends the remote control certificate to the client.

[0040] In an embodiment of the present invention, the cloud service end includes at least a vehicle networking service platform and a certificate management platform, wherein the certificate management platform is responsible for issuing certificates to the client and the vehicle terminal for end-to-end encryption support of instructions. The TSP platform (Telematics Service Provider, vehicle networking service platform) is a core business processing system, responsible for account authority management, vehicle status management, vehicle positioning information processing, vehicle search instruction processing, etc. When the vehicle networking service platform receives a remote control certificate application instruction sent by the client, the remote control certificate application instruction is transmitted to the certificate management platform; the certificate management platform generates a remote control certificate and sends it to the vehicle networking service platform, and then the vehicle networking service platform sends the remote control certificate to the client. The instructions are transparently transmitted through the TSP platform and the certificate management platform sends the remote control certificate to ensure that all vehicle control instructions are end-to-end encrypted, thereby ensuring the security of the instructions.

[0041] In one embodiment of the present invention, the cloud service end includes at least: an Internet of Vehicles service platform and a production and sales platform; The method comprises: obtaining a vehicle identification number of a target vehicle to be queried by a current account of the client, performing an authority check on a vehicle search authority of the current account of the client based on the vehicle identification number, and if the authority check passes, sending a location information request of the target vehicle corresponding to the vehicle identification number to the vehicle-mounted terminal, including: Obtaining the vehicle identification number of the target vehicle that the client's current account needs to query; The production and sales platform determines the production and sales status of the target vehicle according to the vehicle identification number of the target vehicle; The Internet of Vehicles service platform performs a permission check on the vehicle search permission of the client's current account based on the production and sales status of the target vehicle. If the permission check passes, a positioning information request for the target vehicle corresponding to the vehicle identification number is sent to the vehicle terminal.

[0042] In an embodiment of the present invention, the cloud service end includes at least a telematics service platform and a production and sales platform, wherein the TSP platform (Telematics Service Provider) is a core business processing system responsible for account authority management, vehicle status management, vehicle positioning information processing, vehicle search instruction processing, etc. The production and sales platform is responsible for synchronizing the current production status or sales status of the vehicle to the TSP platform to support the TSP platform in determining whether the vehicle can be located or searched.

[0043] When the TSP platform obtains the VIN code of the target vehicle that the client's current account needs to query, the production and sales platform will determine the production and sales status of the target vehicle based on the VIN code. After that, the TSP platform will verify the vehicle search permission of the client's current account based on the production and sales status of the target vehicle. Only when the permission verification passes, the target vehicle's positioning information request will be sent to the vehicle terminal.

[0044] Restrictions based on the production and sales status of the vehicle and the account's vehicle search permissions can help companies better manage the vehicle life cycle. From production and sales to after-sales service, each stage has clear permission controls, which can limit information viewing to unsold vehicles without affecting the owner's use of the vehicle after it is sold.

[0045] In one embodiment of the present invention, the production and sales status includes: actually sold, stored in warehouse but not shipped, and stored in warehouse but shipped; The Internet of Vehicles service platform performs a permission check on the vehicle search permission of the current account of the client based on the production and sales status of the target vehicle, including: When the production and sales status of the target vehicle is actually sold, the authority check fails; If the production and sales status of the target vehicle is warehoused-not shipped, and the account has the first vehicle search permission, the permission check is passed; When the production and sales status of the target vehicle is warehoused-shipped, and the account has the second vehicle search permission, the permission check passes.

[0046] In an embodiment of the present invention, the production and sales status can be divided into sold, warehoused but not shipped, and warehoused but shipped. The Internet of Vehicles service platform performs a permission check on the vehicle search permission of the client's current account based on the production and sales status of the target vehicle. Specifically, it may include: when the production and sales status of the target vehicle is sold, the target vehicle has left the factory's offline vehicle parking area and has been delivered or is being delivered to the user. At this time, no matter whether the vehicle search permission of the account is the first vehicle search permission, the second vehicle search permission, or other vehicle search permissions, the permission check will fail, and the positioning information of the sold vehicle cannot be viewed or the sold vehicle cannot be controlled. The permission to the sold vehicle is restricted without affecting the use of the vehicle by the owner after the sale. When the production and sales status of the target vehicle is "In-warehouse-Not-shipped" and the account has the first vehicle search permission, the permission check passes, because the target vehicle that has been in-warehouse-Not-shipped will be parked in the factory's offline vehicle parking area, that is, within the preset range, so the account can obtain the positioning information of the target vehicle that has been in-warehouse-Not-shipped and control the target vehicle; when the production and sales status of the target vehicle is "In-warehouse-Shipped" and the account has the second vehicle search permission, the permission check passes, because the vehicle that has been in-warehouse-Shipped has left the factory's offline vehicle parking area, that is, within the preset range, and is on the way to other locations, so the account can obtain the positioning information of the target vehicle that has been in-warehouse-Shipped but cannot control the vehicle.

[0047] Based on the production and sales status, the production and sales status of the vehicle is divided into sold, warehoused but not shipped, and warehoused but shipped. Vehicles in different production and sales statuses can be controlled by different vehicle search permissions, which can help companies better manage the life cycle of vehicles. From production, sales to after-sales service, each stage has clear permission control and is restricted to information viewing only for unsold vehicles, which will not affect the owner's use of the vehicle after the sale.

[0048] In an optional embodiment of the present invention, when receiving the encrypted vehicle search instruction sent by the client, performing a secondary authority check on the vehicle search authority of the current account of the client based on the vehicle identification number, and if the secondary authority check passes, transmitting the vehicle search instruction to the vehicle terminal, including: When the production and sales status of the target vehicle is warehoused-not shipped, and the account has the first vehicle search permission, the permission check passes, and the encrypted vehicle search instruction is transparently transmitted to the vehicle-mounted terminal.

[0049] In an embodiment of the present invention, after the cloud server sends the positioning information of the target vehicle to the client, the client will issue a vehicle search instruction based on the positioning information of the target vehicle to control the vehicle to flash lights, honk, etc. At this time, if the cloud server receives the encrypted vehicle search instruction sent by the client, specifically, the client signs the instruction by using the private key generated when applying for the certificate, and sends the signed instruction to the TSP platform. The TSP platform performs a secondary permission check on the vehicle search permission of the client's current account based on the VIN code. Only when the production and sales status of the target vehicle is warehoused-not shipped, and the account has the first vehicle search permission, the secondary permission check passes. At this time, the vehicle search instruction will be transmitted to the vehicle terminal, and the cloud server will not parse the vehicle search instruction when transmitting the vehicle search instruction. All vehicle search instructions are end-to-end encrypted and will not be tampered with or leaked by network, cloud and other vulnerabilities or attackers, thereby ensuring the security of the vehicle search instruction.

[0050] In an embodiment of the present invention, application information of an account is obtained from an account application terminal; corresponding vehicle search permissions are set according to the application information, the vehicle identification number of the target vehicle queried by the current account is obtained, and a permission check is performed on the vehicle search permission of the current account based on the vehicle identification number. If the permission check passes, the positioning information of the target vehicle is obtained through the vehicle-mounted terminal. If an encrypted vehicle search instruction is received, a secondary permission check is performed on the vehicle search permission of the current account of the client based on the vehicle identification number. If the check passes, the vehicle search instruction is transmitted to the vehicle-mounted terminal, so that the vehicle-mounted terminal performs a certificate check on the vehicle search instruction. If the certificate check passes, the vehicle search instruction is executed. Setting the corresponding vehicle search permission through the application information can avoid abuse of permissions and systems, and all vehicle control instructions are end-to-end encrypted to ensure the security of operations.
