The PC5-PEPS system keeps low power consumption under the sleeping condition, when the intelligent antenna array in front of and behind the V2X vehicle firstly carries out automatic intelligent scanning (electric scanning technology and non-mechanical scanning) when detecting that the terminal equipment sends information and requests, the direction of the terminal equipment is quickly locked, and then the performances of the antenna array such as radiation direction, radiation beam shape, radiation power and the like are automatically adjusted, so that the strongest beam is quickly aligned to the terminal equipment, and the operations such as accurate positioning, distance measurement, intelligent digital key authority openness degree judgment and the like are realized.

The following embodiments of the present application may be explained on the premise that the terminal device and the vehicle establish a connection for a non-first time.

The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.

Fig. 3 is a flowchart illustrating a terminal device-based vehicle control method according to an embodiment of the present disclosure. The execution subject of the embodiment shown in fig. 3 may be the terminal device shown in fig. 1 and 2, and the vehicle control method is described below.

S302: a connection request is sent to the vehicle over the PC5 air interface sidelink.

In S302, when the terminal device wants to establish a communication connection with the vehicle, it may send a connection request to the vehicle through the air interface link of the PC 5.

In one possible implementation, the terminal device may send the connection request to the vehicle by:

the vehicle can broadcast messages outwards at intervals in a certain area centered on the vehicle, once the terminal device enters the area, the terminal device can receive the messages broadcasted by the vehicle, at this time, the vehicle can wake up the terminal device (the terminal device is in a dormant state before so as to save electric quantity), and after the terminal device is woken up, the terminal device can send a connection request to the vehicle through a PC5 air interface sidelink.

The certain area centered on the vehicle may be a circular area with a radius of a first preset threshold, where the first preset threshold may be a certain value in a value range [500, 1000] (unit meter), and may be determined according to practical situations, where the determination is not specifically limited, and the accuracy of the first preset threshold may be controlled to be about 20 cm.

That is, in a case where the distance between the terminal device and the vehicle is less than or equal to the first preset threshold, the terminal device may send a connection request to the vehicle through the PC5 air interface sidelink to request establishment of a communication connection with the vehicle.

Alternatively, the terminal device may send the connection request to the vehicle in other manners, for example, the terminal device may actively broadcast a message to the outside in an area centered on the terminal device and having a radius of the first preset threshold, and the vehicle may receive the message when the distance between the terminal device and the vehicle is smaller than or equal to the first preset threshold, and at this time, the terminal device may send the connection request to the vehicle through the air interface sidelink of the PC5 to request to establish a communication connection with the vehicle. The embodiment does not exemplify other implementations.

S304: after receiving the indication information fed back by the vehicle according to the connection request, sending the equipment information and the first authentication information of the terminal equipment to the vehicle, and receiving the vehicle information and the second authentication information of the vehicle, which are fed back by the vehicle according to the connection request through a PC5 air interface side link.

In S304, the vehicle may know that the terminal device wants to establish a communication connection with the vehicle when receiving the connection request sent by the terminal device, and at this time, the vehicle may send instruction information to the terminal device to instruct the terminal device to feed back its device information and authentication information to the vehicle, so that the vehicle authenticates the terminal device. The device information of the terminal device may include, but is not limited to, a user identifier of a user using the terminal device and a device identifier of the terminal device, and the authentication information of the terminal device includes, but is not limited to, legal information such as a CA certificate of the terminal device, and here, for convenience of distinction, the authentication information of the terminal device may be referred to as first authentication information.

Meanwhile, the vehicle may also send its own vehicle information and authentication information to the terminal device through the air interface sidelink of the PC5, so that the terminal device authenticates the vehicle, where the vehicle information of the vehicle includes, but is not limited to, a vehicle identifier of the vehicle and version information of the vehicle, and the authentication information of the vehicle includes, but is not limited to, legal information such as a CA certificate of the vehicle, and here, for convenience of distinction, the authentication information of the vehicle may be referred to as second authentication information.

It should be noted that, since the implementation of S302 and S304 in this embodiment is based on the premise that the terminal device and the vehicle do not establish the communication connection for the first time, and when the connection is established for the first time, the terminal device stores the first authentication information locally, and the vehicle stores the second authentication information locally (see the detailed description of the embodiments shown in fig. 4 and fig. 5, in detail later), in S304, after receiving the indication information of the vehicle, the terminal device may obtain the first authentication information of the terminal device from the local, and send the first authentication information and the own device information to the vehicle. Similarly, after receiving the connection request from the terminal device, the vehicle may obtain the second authentication information of the vehicle from the local, and send the second authentication information and the vehicle information to the terminal device.

S306: and after the vehicle is authenticated according to the vehicle information and the second authentication information and authentication passing information fed back after the vehicle passes the terminal equipment authentication according to the equipment information and the first authentication information is received, establishing communication connection with the vehicle based on the air interface sidelink of the PC 5.

In S306, the terminal device may authenticate the vehicle according to the received vehicle information and the second authentication information, and the vehicle may authenticate the terminal device according to the received device information and the first authentication information. Because the terminal device and the vehicle are not connected for the first time, and when the connection is established before, the terminal device stores the vehicle information and the legal information of the vehicle locally, and the vehicle stores the device information and the legal information of the terminal device locally, the terminal device and the vehicle can be authenticated directly, after the authentication is passed, the vehicle feeds back the authentication passing information to the terminal device, the terminal device also feeds back the authentication passing information to the vehicle, and after the vehicle and the terminal device receive the authentication passing information fed back by the other party, the communication connection based on the air interface side link of the PC5 can be established formally.

The above S302 to S306 are all described on the premise that the terminal device and the vehicle do not establish a connection for the first time, and how to implement a communication connection in the case where the terminal device and the vehicle establish a communication connection for the first time will be described in detail below with reference to fig. 4 and 5.

Fig. 4 is a flowchart illustrating a method for performing identity authentication when a terminal device and a vehicle establish a connection for the first time according to an embodiment of the present application, which may specifically include the following steps.

S401: the terminal equipment requests to establish connection with the vehicle through the air interface sidelink of the PC 5.

Specific implementation manners may refer to the specific implementation manner of S302 described above, and a repeated description is not repeated here.

S402: the vehicle instructs the terminal device to transmit the device information of the terminal device to the vehicle, and transmits the vehicle information of the vehicle to the terminal device through the air interface sidelink of the PC 5.

Alternatively, the vehicle may instruct the terminal device to send the device information and the authentication information of the terminal device to the vehicle, but since the terminal device and the vehicle establish connection for the first time, even if the vehicle instructs the terminal device to feed back the authentication information to the vehicle at the same time, the terminal device cannot realize the feedback of the authentication information.

Similarly, since the terminal device and the vehicle are connected for the first time, the vehicle does not locally store the authentication information, and only the vehicle information of the vehicle can be sent to the terminal device.

S403: the terminal device transmits the device information of the terminal device to the vehicle.

S404: and the terminal equipment establishes communication connection with the network equipment.

In this embodiment, if the terminal device and the vehicle are connected, the terminal device stores vehicle information of the vehicle, and the vehicle also stores device information of the terminal device, so that after receiving the vehicle information of the vehicle, the terminal device may compare the vehicle information with locally stored vehicle information, and if the vehicle information is not locally stored, it may be stated that the vehicle and the terminal device are connected for the first time, and at this time, the terminal device establishes a communication connection with the network device, so as to authenticate the vehicle by means of the network device.

The network device may be understood as a path of a mobile network, and may include a radio access network (mobile base station), a bearer network, a core network, a backbone network, and the like. The mobile communication technology is forward compatible, and in the embodiment of the application, the 5G communication equipment can automatically switch to the 4G, 3G or 2G base station for communication without the 5G base station.

S405: the terminal equipment sends a first authentication request to the Internet of vehicles system security management platform through the network equipment.

The vehicle networking system security management platform (hereinafter, may be referred to as a management platform for short) may be understood as a platform dedicated to providing background services for vehicles, belongs to a trusted authority, and may authenticate legitimacy of terminal devices and vehicles. After the terminal device establishes communication connection with the network device, an authentication request can be sent to the management platform to request the management platform to assist in completing the authentication of the vehicle.

The authentication request sent by the terminal device to the management platform may include device information of the terminal device and vehicle information of the vehicle, and for convenience of distinction, the authentication request sent by the terminal device to the management platform may be referred to as a first authentication request.

S406: the management platform authenticates the vehicle.

In this embodiment, the management platform may store the device information of the terminal device and the vehicle information of the vehicle in advance. Specifically, after the user purchases the vehicle, the user information, the device information of the terminal device used by the user and the vehicle information of the vehicle may be uploaded to the management platform through the front-end application software of the management platform, or the management platform may actively enter the user information, the device information of the terminal device and the vehicle information of the vehicle, which is not specifically limited herein.

In this way, when the management platform authenticates the vehicle, the vehicle information of the vehicle, which is recorded in advance, may be searched according to the vehicle identifier included in the vehicle information, and the searched vehicle information is compared with the vehicle information sent when the terminal device requests authentication, if the vehicle information is consistent, the vehicle may be legal, the authentication is passed, if the vehicle information is inconsistent, the vehicle may be illegal, the authentication is not passed, and this embodiment takes the authentication pass as an example for explanation.

S407: and the management platform sends the first authentication information and the vehicle legal confirmation information to the terminal equipment through the network equipment.

The management platform can feed back the vehicle legal confirmation information to the terminal equipment after determining that the vehicle is legal, and in addition, the management platform can also send first authentication information to the terminal equipment, so that the vehicle can directly authenticate the terminal equipment based on the first authentication information when the subsequent terminal equipment and the vehicle are connected again.

S408: the terminal device stores the first authentication information and vehicle information of the vehicle.

The terminal device can store the first authentication information in the local after receiving the first authentication information issued by the management platform, can determine that the vehicle is legal after receiving the vehicle legal confirmation information issued by the management platform, and stores the vehicle information of the vehicle in the local, so that when communication connection is established with the vehicle subsequently, the vehicle can be authenticated based on the locally stored first authentication information and the vehicle information of the vehicle, and the vehicle is not required to be authenticated by means of the network device and the car networking system safety management platform.

S409: the vehicle establishes a communication connection with the network device.

S410: and the vehicle sends a second authentication request to the Internet of vehicles system security management platform through the network equipment.

The second authentication request may include vehicle information of the vehicle and device information of the terminal device, and the second authentication request is used to request authentication of the terminal device.

S411: and the management platform authenticates the terminal equipment.

Here, the authentication pass of the terminal device is explained as an example.

The third preset threshold may be a certain value in a value range [3, 5] (unit meter), and may be specifically determined according to an actual situation, where no specific limitation is made, where the precision of the third preset threshold may be controlled to be about 10 cm.

When the distance between the vehicle and the terminal equipment is determined to be smaller than or equal to the third preset threshold value and larger than the fourth preset threshold value, the vehicle can be unlocked automatically.

The fourth preset threshold may be a certain value in a value range [1, 1.2] (unit meter), and may be specifically determined according to an actual situation, where no specific limitation is made, where the precision of the fourth preset threshold may be controlled to be about 5 cm.

Optionally, after the vehicle is automatically unlocked, whether an obstacle exists in a preset range of a door of the vehicle can be identified to control the opening degree of the door, if no obstacle exists, the door can be directly opened, if an obstacle exists, the door is only unlocked and not opened, and an alarm prompt is sent to the terminal device. In addition, when the vehicle and the terminal device are in a communication range (up to 1000m), the vehicle door is unlocked or opened abnormally, and the vehicle can also send an alarm prompt to the terminal device to inform a user of abnormal conditions so that the user can take corresponding measures.

When the distance between the vehicle and the terminal device is determined to be smaller than or equal to the fourth preset threshold, it can be determined that the user is located in the vehicle, and the vehicle can be automatically started at the moment.

Optionally, when the vehicle is automatically started, the state of the vehicle after the vehicle is started may be set according to the signal carrying the setting information sent by the terminal device, and the specific implementation manner may refer to the corresponding content in the embodiment shown in fig. 3, and will not be described again here.

To facilitate understanding of the control process of the vehicle described above, reference may be made to fig. 7. Fig. 7 is a scene schematic diagram of a terminal device-based vehicle control method according to an embodiment of the present application.

Fig. 7 is a diagram that divides the area around the vehicle into 5 areas by using the first preset threshold, the second preset threshold, the third preset threshold and the fourth preset threshold as the center of the vehicle, wherein:

the area within the circle (1) is an imperceptible startup PS area (area D shown in fig. 7), and in this area, the distance between the terminal device and the vehicle is less than or equal to the fourth preset threshold;

an area outside the circle (1) and inside the circle (2) is an imperceptible entering PE area (area C shown in FIG. 7), and in the area, the distance between the terminal device and the vehicle is greater than a fourth preset threshold and less than or equal to a third preset threshold;

an area outside the circle (2) and inside the circle (3) is a welcome area (an area B shown in fig. 7), and in the area, the distance between the terminal device and the vehicle is greater than a third preset threshold and less than or equal to a second preset threshold;

an area outside the circle (3) and inside the circle (4) is a vehicle searching area (area a shown in fig. 7), and in the area, the distance between the terminal device and the vehicle is greater than a second preset threshold and smaller than or equal to a first preset threshold;

the area outside the circle (4) is the other area, and the distance between the terminal device and the vehicle in the area is larger than the first preset threshold value.

In other areas, no interaction between the vehicle and the terminal device takes place.

In the vehicle searching area, the terminal device establishes communication connection with the vehicle based on a PC5 air interface sideline, the vehicle end identifies the position and distance of the terminal device and authorizes the vehicle searching function to be started, and at the moment, the vehicle can send own state information to the terminal device.

In the welcome zone, the vehicle can start the welcome function: and opening the welcome lamp, the welcome music, the lighting indicator lamp and other welcome applications.

In the PE area, the vehicle can start an uninformed PE function, automatically unlock or lock, automatically open the door, and identify whether an obstacle is nearby in the vehicle to control the opening degree of the door. When the distance between the detected obstacle and the vehicle door is less than 10cm (or other distances), the vehicle is unlocked and not opened, and alarm sound prompt is performed.

And in the PS area, when the vehicle detects that the terminal equipment is positioned in the vehicle, the vehicle is automatically started.

Optionally, after the vehicle and the terminal device establish a communication connection, an automatic wireless connection without sensing between the vehicle and the terminal device can be realized, and data or files are transmitted, at this time, the terminal device is equivalent to an edge node of the vehicle and is a plurality of edge nodes which can cooperate with each other; the wireless real-time automatic screen projection of the terminal device to a vehicle screen can be realized (for example, a 5G NR smart phone does not sense the wireless screen projection); the sharing and management of the resources such as terminal equipment, vehicle software and hardware, calculation force processing and the like can be realized, for example, under the condition that no mobile network exists in an underground parking lot or an underground garage, convenient sharing and permission setting management can still be realized. Certainly, when a mobile network exists, more distant sharing can be realized; and when a plurality of terminal devices are arranged in the vehicle, the vehicle can use the terminal devices as edge cloud nodes to realize real-time processing of mass data, and provide real-time and high-performance data computing capability processing functions for services such as vehicle networking and automatic driving ADAS.

In addition, the vehicle can also share the navigation and multimedia video information base of the terminal equipment in real time, because the mobile phone navigation is better used, the multimedia entertainment resources are richer, but the screen of the terminal equipment is smaller, and the sound system is much weaker than that of the vehicle, so that the large screen and the sound system of the vehicle can be borrowed. When the involved calculation is complex and the processing requirement is large, the processing capacities of the vehicle and the terminal equipment can be called simultaneously, so that the user experience can be greatly improved.

It should be noted that, during the process of establishing the communication connection between the terminal device and the vehicle, and after the communication connection is established, the terminal device and the vehicle may encrypt the interactive information during the interaction process, for example, encrypt the interactive information using public and private keys, which is safer and more reliable, and can ensure the security of the interactive information, thereby implementing the application with higher security level.

According to the technical scheme provided by the embodiment of the application, the PC5 air interface communication technology is utilized to realize the application of the terminal equipment to the safe and quick intelligent digital key of the vehicle. Specifically, when the vehicle is controlled, the terminal device may request to establish connection with the vehicle through the air interface sidelink of the PC5, the vehicle sends its own device information and authentication information to the terminal device, and requests the terminal device to feed back its own device information and authentication information, and then after the terminal device and the vehicle pass the authentication of the opposite party, the communication connection based on the air interface sidelink of the PC5 is established, and further, the automatic control of the vehicle is realized based on the direct communication between the terminal device and the vehicle. The embodiment of the application adopts the 5G NR latest direct communication PC5 sidelink technology, has low end-to-end time delay and stronger real-time property, can realize farther or ultra-far (1000m) distance communication, and has higher communication safety, lower time delay, more reliability, stronger connectivity and large connection density capability in the birth.

In addition, after the terminal device and the vehicle pass the first authentication and establish the communication connection, the terminal device and the vehicle can directly communicate when establishing the communication connection subsequently, and the participation of mobile network devices is not needed, so that the automatic control of the vehicle can be realized even under the condition of no mobile network signal, the vehicle can be flexibly applied to more application scenes, the application range is wider, extra traffic cost can not be generated, and the vehicle is quicker and more convenient.
