Detailed Description

With the continuous development of internet technology, the internet of vehicles is closely associated with the daily travel of people, and the internet of vehicles is a huge interactive network formed by information such as vehicle positions, speeds and routes. The vehicle can complete the collection of self environment and state information through devices such as a Global Positioning System (GPS), Radio Frequency Identification (RFID), a sensor, camera image processing and the like; all vehicles can transmit and gather various information of the vehicles to a central processing unit through the internet technology; through computer technology, the information of a large number of vehicles can be analyzed and processed, so that the optimal routes of different vehicles can be calculated, road conditions can be reported in time, and signal lamp periods can be arranged. The Internet of vehicles is based on an intra-vehicle network, an inter-vehicle network and a vehicle-mounted mobile Internet, and can realize wireless communication and information exchange between vehicles, between vehicles and roads, between vehicles and pedestrians, between vehicles and the Internet and the like according to an agreed communication protocol and a data interaction standard.

The method is mainly applied to a specific scene in the internet of vehicles, namely an Automatic Valet Parking (AVP) scene, as shown in fig. 1, the AVP refers to a system in which a driver parks a vehicle in a designated Parking area in front of a Parking lot and activates automatic Valet Parking. The AVP is guided by the parking lot, the automobile automatically passes through the barrier gate, an empty parking space is found in the parking lot for parking, and after the driver presses the mobile phone button, the automobile can automatically return to the designated parking area. Compared with the traditional manual parking, the AVP has the following advantages: the burden of people parking in person is avoided, the time is saved, the utilization efficiency of the parking lot is improved, the blind area detection is realized, and the like. The AVP includes 2 large application scenarios, respectively: private car replaces passenger parking and shares car parking and car taking.

One existing AVP process is: the mobile phone initiates a parking request to the cloud platform, the cloud platform verifies the parking request, the cloud platform issues the parking request to the parking lot server after the verification is passed, then the parking lot server establishes connection with the vehicle to be parked through the network, and the vehicle to be parked is guided by the parking lot server to park in the parking space. It can be seen that the existing AVP mainly verifies the parking request initiated by the user, that is, as long as the identity information of the initiator of the parking request is verified, the parking lot server may issue a parking instruction to the vehicle to be parked to perform the parking operation, but the parking instruction received by the vehicle to be parked may not be issued by the parking lot server, and the vehicle to be parked may be driven to other places under the guidance of an unauthorized malicious instruction, thereby having a greater potential safety hazard.

Therefore, the vehicle control method is provided, the vehicle can execute the vehicle control command only after the vehicle control command is verified to be the vehicle control command authorized by the vehicle-enterprise server, and potential safety hazards are reduced.

The multi-party interaction scene related in the application can be as shown in fig. 2, and comprises a vehicle, a terminal, a vehicle-enterprise server and a parking lot server, data interaction is performed among the parties through the internet, wherein a user can initiate a vehicle control request to the vehicle-enterprise server through the terminal, the vehicle-enterprise server can be a server which is controlled by a vehicle enterprise producing the vehicle and is used for remotely managing vehicle state information, the vehicle-enterprise server needs to perform identity verification on the terminal and the vehicle, the parking lot server is informed after the verification is passed, the parking lot server is given vehicle control authority according to the application authority request of the parking lot server, and finally, after the vehicle verifies a vehicle control instruction issued by the parking lot server (whether the vehicle control instruction passes the authorization of the vehicle-enterprise server is verified), the vehicle can execute the vehicle control instruction to complete automatic parking or vehicle taking.

Referring next to fig. 3, an embodiment of a vehicle control method according to an embodiment of the present application includes:

301. and the terminal sends a vehicle control request to the vehicle-enterprise server.

In this embodiment, the terminal may send the vehicle control request to the vehicle-enterprise server through the application program bound to the vehicle-enterprise server. It can be understood that the vehicle control request may include a parking request or a recall request according to different requirements of the user, the user may use the terminal to initiate the parking request to the vehicle-enterprise server if the vehicle is in a waiting state, and the user may use the terminal to initiate the recall request to the vehicle-enterprise server if the vehicle is in a parked state. Specifically, the terminal can display a parking lot identifier on the interface according to the GPS information, the user can select the parking lot on the interface, the entrance identifier (which can be one or more entrances) of the parking lot can be further displayed on the terminal interface after the parking lot is determined, the user then selects an entrance to enter the parking lot, and then the terminal sends a vehicle control request carrying the vehicle identifier, the parking lot identifier and the parking lot entrance identifier to the vehicle-enterprise server. It is understood that the vehicle identifier in the present application may be a Vehicle Identification Number (VIN) uniquely corresponding to the vehicle.

It should be noted that a terminal in this embodiment may be referred to as a User Equipment (UE), a Mobile Station (MS), a mobile terminal (mobile terminal), an intelligent terminal, and the like, and the terminal may communicate with one or more core networks through a Radio Access Network (RAN). For example, the terminal equipment may be a mobile telephone (or so-called "cellular" telephone), a computer with a mobile terminal, etc., and the terminal equipment may also be a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device and terminal equipment in future NR networks, which exchange voice or data with a radio access network, which will be described in this application in the general sense of a UE.

302. The vehicle-enterprise server judges whether the vehicle control request meets a preset condition, if not, the step 303 is executed, and if so, the step 304 is executed.

In this embodiment, after receiving the vehicle control request, the vehicle-enterprise server needs to verify the vehicle control request, that is, determine whether the vehicle control request meets a preset condition. Specifically, the vehicle-enterprise server may complete mutual authentication with the vehicle, the parking lot server, and the terminal in advance, and after receiving the vehicle control request, the vehicle-enterprise server may verify whether the information on the terminal and the parking lot carried in the vehicle control request matches the authentication information completed in advance.

303. The vehicle-enterprise server refuses the vehicle control request.

In this embodiment, if the vehicle control request does not satisfy the preset condition, the vehicle-enterprise server rejects the vehicle control request.

304. And the vehicle-enterprise server sends a vehicle control notification message carrying the vehicle identification to the parking lot server.

In this embodiment, if the vehicle control request meets the preset condition, the vehicle-enterprise server sends a vehicle control notification message carrying a vehicle identifier to the parking lot server to indicate that the parking lot can prepare for controlling the vehicle, and the parking lot server can determine the vehicle corresponding to the vehicle control request according to the vehicle identifier.

305. And the parking lot server sends a vehicle control authority request carrying the vehicle identification to the vehicle-enterprise server.

In this embodiment, after receiving the vehicle control notification message, the parking lot server sends a vehicle control permission request carrying the vehicle identifier to the vehicle-enterprise server. It can be understood that, since the parking lot server may receive the vehicle control notification message sent by the impersonating vehicle enterprise server, in order to reduce the potential safety hazard, the parking lot server needs to apply for the vehicle control permission from the vehicle enterprise server corresponding to the vehicle, that is, send the vehicle control permission request carrying the vehicle identifier to the vehicle enterprise server.

306. The car-enterprise server generates a car control token.

In this embodiment, after receiving a car control authority request sent by a parking lot server, a car enterprise server may first verify whether a vehicle corresponding to a vehicle identifier carried in the car control authority request is in a state of a car to be controlled, and if the vehicle is actually recorded by the car enterprise server locally, the car enterprise server will generate a car control token including a digital signature of the car enterprise server, and in addition, the car control token may further include at least one of a parking lot identifier, a vehicle identifier, a car enterprise server identifier, authority of the car control token, and a valid period of the car control token, where the car enterprise server identifier may indicate a generator of the car control token, the parking lot server may indicate an applicant of the car control token, the vehicle identifier may indicate a receiver of the car control token, and the authority of the car control token is used for indicating a purpose (e.g., for controlling a car) of the car control token, the validity period of the car control token may indicate how long the car control token may remain valid, and if the car control is not finished within the validity period of one car control token, in order to ensure the safety of the car control, the parking lot server needs to repeat step 305 above and add an expired car control token to the newly transmitted car control permission request to prove that the current car control permission request is a new request based on the previous car control permission request.

It should be noted that the digital signature is a digital string that can only be generated by the sender of the information and cannot be forged by others, and the digital string is also a valid proof of the authenticity of the information sent by the sender of the information. Specifically, the vehicle-enterprise server generates a digest of the vehicle control token by using a hash function, then encrypts the digest by using a private key of the vehicle-enterprise server, and sends the encrypted digest to the parking lot server together as a digital signature and a response containing the vehicle control token. The digital signature can determine that the message is actually signed and sent by the vehicle-enterprise server, because other people cannot obtain the private key of the vehicle-enterprise server, the signature of the vehicle-enterprise server cannot be counterfeited, and in addition, the digital signature can determine the integrity of the vehicle control token, because the digital signature is characterized in that the digital signature represents the characteristics of the vehicle control token, if the vehicle control token is changed, the value of the digital signature can also be changed.

307. And the vehicle enterprise server sends a vehicle control permission response carrying the vehicle control token to the parking lot server.

308. The parking lot server sends a vehicle control instruction carrying a vehicle control token to the vehicle.

In this embodiment, after receiving the car control token issued by the car enterprise server, the parking lot server may add the car control token to the car control command and forward the car control command to the vehicle. It can be understood that the vehicle control command may include at least one of information of a destination position, a speed, and a direction that the vehicle needs to drive into, and is not limited herein.

It can be understood that the camera may also upload the shot car logo to the parking lot server, and the parking lot server matches the car logo stored locally, thereby determining the car enterprise server corresponding to the successfully matched car logo.

505. And the parking lot server sends a license plate report message to the vehicle-enterprise server.

In this embodiment, after the parking lot server determines the vehicle-enterprise server, the identified license plate number may be sent to the vehicle-enterprise server through a license plate report message, so that the vehicle-enterprise server stores the license plate number. It can be understood that the license plate report message may also carry the identifier of the specified location to indicate the current status information (to be parked or recalled) and the location information of the vehicle.

506. And the terminal sends a vehicle control request to the vehicle-enterprise server.

In this embodiment, step 506 is similar to step 301 in the embodiment shown in fig. 3, and is not described here again.

It should be noted that the steps after step 506 of this embodiment are similar to steps 406 and 420 of the embodiment shown in fig. 4, and detailed description thereof is omitted here.

As can be seen from the above description, the difference between this embodiment and the embodiment shown in fig. 4 is that the vehicle-enterprise server does not need to actively send a license plate request to the parking lot server, and a vehicle entering a designated location of the parking lot can trigger the parking lot server to actively identify the license plate number.
