Detailed ways

Network function and application technology refers to the information exchange between vehicles and the outside world (vehicles, infrastructure, pedestrians, networks, etc.) using communication technology. This function is not limited to the scope of the vehicle itself, but also involves intersection traffic support and violation warnings. , accident rescue and other functions and services, as well as in-vehicle communication devices, communication protocols and corresponding interface interfaces, including but not limited to V2X technology. Among them, V2X technology refers to the communication between the vehicle-mounted unit and other equipment, including but not limited to the communication between the vehicle-mounted unit (V2V), the vehicle-mounted unit and the infrastructure communication (V2I), the vehicle-mounted unit and the pedestrian equipment communication (V2P), the vehicle-mounted unit and the Communication between networks (V2N).

Networking technology can include numerous functional applications, which are defined by corresponding application standards. The message layer standard inherits the application layer standard. Taking V2X as an example, there are currently five message sets for V2X applications in the industry, including basic vehicle safety messages (BSM), map messages (MAP), traffic events and traffic sign messages (also known as roadside information). , RSI) message), roadside safety message (basic safety message, RSM), signal light message (signal phase and timing, SPAT).

Vehicle identity management is one of the important tasks of traffic management. With the gradual development of traffic management digitization, vehicle identification is no longer limited to traditional license plate numbers, and the concept of vehicle digital identification emerges as the times require. Generally, the vehicle digital ID is unique. Taking V2X as an example, considering the identity privacy of the vehicle, the ID is usually not broadcast directly over the air interface. Currently, it is defined in the communication standard that the vehicle's randomly generated ID can be sent in the BSM message. A random number (such as a temporary ID), so that the outside world (such as other surrounding vehicles, roadside units (RSU), etc.) knows the existence of the vehicle, and the generation method of the temporary ID (generated based on a random algorithm) has been obtained Consensus within the communications industry.

However, in the field of traffic management, it is necessary to consider both the privacy of the identity of the Internet of Vehicles terminal, and the needs of management and monitoring. The original temporary identification has not formed a consensus in the field of traffic management standards, and the temporary The randomness of identity identification will cause difficulties in the implementation of management and monitoring of IoV terminals. Therefore, how to manage IoV terminals is still an important problem that needs to be solved urgently.

In view of this, the embodiments of the present application provide a vehicle management method and a communication device, which are helpful for realizing the identification and intelligent management of the target vehicle by other communication devices. Among them, the method and the device are based on the same technical concept. Since the principles of the method and the device to solve the problem are similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

Computer system 160 may include at least one processor 161 that executes instructions 1631 stored in a non-transitory computer-readable medium such as memory 163 . Computer system 160 may also be a plurality of computing devices that control individual components or subsystems of target vehicle 100 in a distributed fashion.

The processor 161 may be any conventional processor, such as a commercially available central processing unit (CPU). Alternatively, the processor may be a dedicated device such as application specific integrated circuits (ASIC) or other hardware-based processors. Although FIG. 3 functionally illustrates a processor, memory, and other elements of the computer system 160 in the same blocks, one of ordinary skill in the art will understand that the processor, computer, or memory may actually include a can or Multiple processors, computers, or memories that are not stored within the same physical enclosure. For example, the memory may be a hard drive or other storage medium located within an enclosure other than computer system 160 . Thus, reference to a processor or computer will be understood to include reference to a collection of processors or computers or memories that may or may not operate in parallel. Rather than using a single processor to perform the steps described herein, some components such as the steering and deceleration components may each have their own processor that only performs computations related to component-specific functions .

In various aspects described herein, a processor may be located remotely from the vehicle and in wireless communication with the vehicle. In other aspects, some of the processes described herein are performed on a processor disposed within the vehicle while others are performed by a remote processor, including taking steps necessary to perform a single maneuver.

A self-driving car traveling on a road, such as the target vehicle 100 above, can identify objects within its surroundings to determine adjustments to the current speed. The targets may be other vehicles, traffic control devices, or other types of targets. In some examples, each identified target may be considered independently, and based on the target's respective characteristics, such as its current speed, acceleration, distance from the vehicle, etc., may be used to determine the speed at which the autonomous vehicle is to adjust.

Alternatively, the autonomous vehicle target vehicle 100 or a computing device associated with the autonomous vehicle target vehicle 100 (eg, computer system 160, computer vision system 132, memory 163 of FIG. 3) may be based on the characteristics of the identified target and the surrounding environment. state (eg, traffic, rain, ice on the road, etc.) to predict the behavior of the identified target. Optionally, each of the identified objects is dependent on the behavior of each other, so it is also possible to predict the behavior of a single identified object by considering all of the identified objects together. The target vehicle 100 can adjust its speed based on the predicted behavior of the identified target. In other words, the self-driving car can determine what steady state the vehicle will need to adjust to (eg, accelerate, decelerate, or stop) based on the predicted behavior of the target. In this process, other factors may also be considered to determine the speed of the target vehicle 100, such as the lateral position of the target vehicle 100 in the road being traveled, the curvature of the road, the proximity of static and dynamic objects, and the like.

In addition to providing instructions to adjust the speed of the self-driving car, the computing device may also provide instructions to modify the steering angle of the target vehicle 100 so that the self-driving car follows a given trajectory and/or maintains contact with a target in the vicinity of the self-driving car ( For example, safe lateral and longitudinal distances for cars in adjacent lanes on the road.

The above-mentioned target vehicle 100 can be a car, a truck, a motorcycle, a bus, a boat, an airplane, a helicopter, a lawn mower, a recreational vehicle, an amusement park vehicle, construction equipment, a tram, a golf cart, a train, a cart, etc., The embodiments of the present application are not particularly limited.

The vehicle management method of the present application may be implemented by at least two communication devices in each communication device in the communication system shown in FIG. 1 or FIG. 2 in cooperation. The following takes the V2X scenario as an example, in conjunction with the accompanying drawings and embodiments, to introduce in detail the specific implementation steps of the vehicle management method of the present application in different stages.

vehicle identity registration stage

Referring to Figure 4, in the vehicle identity registration stage, the vehicle management method may include the following steps:

S401: The first communication device 1-1 (through the second communication device 1-2) acquires the registration information of the target vehicle.

In this embodiment, the first communication device 1-1 may be integrated in the vehicle management device, which may be the vehicle management device itself, or a component or chip in the vehicle management device. In the following, the first communication device 1-1 may be Replacement with vehicle management device. The vehicle management device may be a device with intelligent vehicle management function corresponding to the traffic management department, and may be a management platform or a server. The vehicle management device may pre-store relevant algorithms and relevant management strategies for vehicles of different types or different states in the local or in the cloud or other storage devices, so that the vehicle management device can realize the intelligence of different vehicles according to the relevant algorithms and relevant management strategies. management.

The target vehicle is any vehicle that has the qualification for registration and registration. The second communication device 1-2 can be integrated in the target vehicle, which can be the target vehicle itself, or a component or chip in the target vehicle. Hereinafter, the second communication device 1-2 2 can be used interchangeably with the target vehicle. In the embodiment of the present application, the communication between the vehicle management device and the target vehicle may be the communication between the first communication device 1-1 and the second communication device 1-2, or the communication between the first communication device 1-1 and the second communication device 1-2. The communication between the target vehicles may be communication between the vehicle management device and the second communication device 1-2.

The registration information of the target vehicle may include any information that the target vehicle needs to provide to the vehicle management device when the target vehicle performs vehicle identity registration with the traffic management department, which may include, but is not limited to, at least one of the target vehicle's vehicle type information, license plate information or registration area information. one. The vehicle management device may store registration information of the target vehicle.

It should be understood that the above registration information may be provided to the first communication device 1-1 by various means such as user input, photographing, scanning, acquisition from the network, etc., or may be sent to the first communication device by the second communication device 1-2 For the device 1-1, this application does not make any limitation on the acquisition method of the registration information. The registration information of the target vehicle can be obtained at one time or obtained in batches. With the gradual development of the digitalization of traffic management and the ever-changing management needs of the traffic management department for the target vehicle, the registration information may also include other information than the above registration information, which is not limited in this application. When the vehicle management mechanism of the traffic management department changes, the first communication device 1-1 can also obtain the relevant information of the vehicle whose identity registration has been completed and put into operation as required, as the subsequent supplementary registration information, which will not be repeated here.

S402: The first communication device 1-1 determines a target algorithm and a target usage strategy according to the registration information of the target vehicle.

In the embodiment of the present application, the target vehicle can register the vehicle identity with the vehicle management device, and after the first communication device 1-1 obtains the registration information of the target vehicle, the vehicle management device can register the identity of the target vehicle, and according to the The registration information determines the target algorithm and target usage policy suitable for the target vehicle in the stored related algorithms and related management policies. Wherein, the vehicle management device may also save the correspondence between the registration information of the target vehicle and the target algorithm. The determined target algorithm and target usage strategy may be synchronously issued to the target vehicle, the target algorithm may be used to generate a management identity of the target vehicle, and the target usage strategy may include instructions for the target vehicle to be based on the management identity. A policy for communicating with other communication devices is identified, and the management identity is used by the other communication devices to identify the target vehicle.

In the embodiments of the present application, for vehicles of different types or different states, the corresponding target algorithms and target usage strategies may be different. The target algorithm and target usage strategy can be used to obtain the management identity of the target vehicle during the vehicle operation and maintenance phase, and enable the target vehicle to communicate with other communication devices based on the management identity. Wherein, the target algorithm has multiple implementation manners, which are not limited in this application. Exemplarily, the first communication device may also send the permanent identity of the target vehicle and/or the target key to the target vehicle; wherein the target algorithm is used to generate the management based on the permanent identity identity; or, the target algorithm is used to generate the management identity based on the permanent identity and the target key. Exemplarily, the target algorithm may also be used to generate the management identity based on a random number. The following will be described in detail with reference to the accompanying drawings and embodiments, which will not be repeated here.

Since the corresponding target algorithms and target usage strategies may be different for vehicles of different types or states, in order to facilitate the vehicle management device to supervise different vehicles, the usage strategies of the management identities corresponding to different vehicles can be defined as the following types: When a request message is received from another communication device that meets the first preset condition, the management identity identifier is fed back, and the request message is used to request to obtain the identity information of the target vehicle; the vehicle type, service type, vehicle status, vehicle status of the target vehicle When at least one of the positions satisfies the second preset condition, communicate with other communication devices based on the management identification; if necessary, the management identification of the self may not be transmitted to other communication devices. In the following, the vehicle operation and maintenance phases will be described in detail with reference to the accompanying drawings and embodiments, which will not be repeated here.

S403: The first communication device 1-1 sends the target algorithm and the target usage strategy to the target vehicle.

The first communication device 1-1 can synchronously deliver the determined target algorithm and target usage strategy to the target vehicle through wired or wireless communication. It should be understood that the first communication device 1-1 may also send other information to the target vehicle, such as the correspondence between the target algorithm and the registration information of the target vehicle, which is not limited in this application.

It should be understood that, in this embodiment of the present application, when the target algorithm is stored in different devices, the target algorithm may be used to implement different functions. For example, if the target algorithm is stored in the target vehicle (or a cloud device accessible to the target vehicle), the target algorithm can be used to generate the management identity of the target vehicle. If the target algorithm is stored in the vehicle communication device (or a cloud device accessible by the vehicle communication device), the target algorithm can be used to parse the management identity of the target vehicle, and reverse the derivation to confirm the identity of the target vehicle.

S404: The second communication device 1-2 receives and saves the target algorithm and the target usage policy.

The second communication device 1-2 may receive the target algorithm and the target usage policy in a wired or wireless manner, and securely store the target algorithm and the target usage policy in a relevant storage area. The storage area may be a local physical storage area of the target vehicle (for example, an on-board unit OBU), a cloud storage area, or other storage areas, which are not limited in this application. In the subsequent process of vehicle operation, maintenance and supervision, as required, the target vehicle can generate a management ID according to the saved target algorithm, and communicate with other communication devices based on the management ID according to the saved target usage policy, so as to facilitate other communication The device identifies the target vehicle or takes appropriate action on the target vehicle.

For example, if the other communication device is another vehicle, the other vehicle may, for example, decide whether to give way to the target vehicle, so as to provide the target vehicle with good road conditions. If the other communication device is the roadside unit RSU, the roadside unit RSU can report the management identity of the target vehicle to the vehicle management device, so that the vehicle management device can supervise the target vehicle. When the other communication device is a vehicle management device, the vehicle management device can analyze the management identification based on the saved target algorithm, obtain the permanent identification of the target vehicle, and realize the intelligentization of the target vehicle based on the permanent identification. manage.

It is understandable that if the target algorithm and target usage strategy are stored in the local physical storage area of the target vehicle, in order to improve security and prevent the data stored in the target vehicle from being tampered with after being violently obtained, when the target vehicle registers the vehicle identity, The vehicle management device can check the physical security of the components in the target vehicle for storing the target algorithm and the target usage policy, so as to avoid the target vehicle privately leaving an interface to the outside, resulting in leakage and tampering of the target algorithm or the target usage policy. In the case where the protection of the target vehicle is not strict, the target vehicle is not allowed to complete the vehicle identity registration, and the first communication device 1-1 is not allowed to execute the step of S403. At this time, the vehicle management device can notify the target vehicle to check and maintain its own related physical components, in order to meet the prescribed management requirements, so as to complete the vehicle identity registration and safely save the target algorithm and target usage strategy. After the target vehicle completes the vehicle identity registration and safely saves the target algorithm and target usage strategy, the target vehicle can enter the vehicle operation and maintenance phase.

In addition, since the target vehicle may have other identities other than the management identity, such as a permanent identity, a temporary identity, etc., the target usage policy may, for example, further include: indicating that the target vehicle is based on the temporary identity A strategy for communicating with other communication devices; a strategy for instructing the target vehicle to communicate with other communication devices based on the saved permanent identity. In different application scenarios, the target vehicle can use the strategy according to the saved target, based on different The identity identification communicates with different other communication devices, so that other communication devices can realize the identification and intelligent management of the target vehicle. Optionally, in order to ensure security, the permanent identification can be set to be non-transmissible, and the target vehicle communicates with other communication devices only according to the management identification and the temporary identification. For ease of understanding, the permanent identification mark, the temporary identification mark and the management identification mark of the target vehicle are described below.

(1) The permanent identification can be an identification number used to indicate the unique identification of the target vehicle. The permanent identity identifier may be a unique identifier generated by the vehicle management device according to the registration information of the target vehicle and a preset algorithm and used to distinguish the target vehicle.

After the target vehicle completes the vehicle identity registration, the permanent identity of the target vehicle can be synchronously stored in the vehicle management device and the target vehicle. In the vehicle management device, the permanent identification can be used to record relevant management information of the target vehicle in a related manner, such as registration information, and relevant driving routes and traffic violation information after the target vehicle is put into use. In the target vehicle, this permanent identity can be used, for example, to generate an administrative identity, which can be used to communicate with other communication devices during the operation and maintenance phases of the target vehicle.

(2) The temporary identification may be an identification number for the temporary identification of the target vehicle. The temporary identity identifier may be randomly generated according to an algorithm specified in the relevant communication protocol, and may be updated periodically (for example, every 300ms).

From the perspective of protecting the privacy of the target vehicle, the target vehicle can communicate with other vehicles, roadside units, etc. around it based on the temporary identification, so that other vehicles, roadside units, etc. are aware of the existence of the target vehicle.

(3) The management ID can be the vehicle ID used by the traffic management department to exercise management power (for example, traffic checkpoint management, operating vehicle management, etc.). The management ID can be generated by the target vehicle based on the saved target algorithm and the permanent ID. Alternatively, the management ID may be generated by the target vehicle based on the saved target algorithm, the permanent ID and the saved target key. Alternatively, the management identifier may be generated by the target vehicle based on the stored target algorithm, the permanent identifier, the stored target key and a random number (eg, a temporary identifier).

Based on the considerations of privacy, security, management efficiency and other aspects, the target vehicle can use the management ID instead of the permanent ID to communicate with other vehicles, roadside units, vehicle management devices, etc. A side unit, a vehicle management device, etc. identify the target vehicle. The vehicle management device can also analyze the management identification based on the locally stored target algorithm, obtain the permanent identification of the target vehicle, and realize intelligent management of the target vehicle based on the permanent identification.

It can be understood that, in order to improve security, in this embodiment of the present application, the management identity identifier may be changed. Target usage policies can also include update policies that manage identities. Wherein, the update strategy may be used to instruct the target vehicle to update the target algorithm; or, the update strategy may be used to instruct the target vehicle to update the algorithm parameters of the target algorithm. For example, the update policy may include periodic update, or may be update based on request messages from other communication apparatuses, which is not limited in this application. When the update strategy is periodic update, the target usage strategy may further include update frequency. Exemplarily, the update strategy is used to instruct the target vehicle to update the target algorithm, and the update frequency may be the update frequency of the target algorithm (for example, the same as the vehicle annual inspection cycle), and the target vehicle may periodically update the target algorithm according to the update frequency. An update is made to generate an updated management identity based on the updated target algorithm. In the case where the target algorithm is used to generate the management ID based on a permanent ID and a random number (for example, a temporary ID), the random number can be used as a kind of algorithm parameter, and the update strategy is used to instruct the target vehicle to The stored update frequency can also be equal to the update frequency of the random number.

It should be understood that "permanent identification mark", "temporary identification mark" and "management identification mark" are only used to schematically represent the identification marks that may be involved in the vehicle management scheme of the target vehicle, and are not limitations on each identification mark. In this case, permanent identity and temporary identity can also be considered as a management identity. It should be noted that the above-mentioned permanent identification, temporary identification, and management identification may be, for example, character strings composed of numbers, characters, symbols, etc., and this application does not make any limitations on the generation and representation of any of the above identifications. When the target vehicle applies to the vehicle management device for vehicle scrapping, the vehicle management device revokes the permanent identity of the target vehicle, as well as the target algorithm, target key, and target usage policy stored in the target vehicle.

In this embodiment of the present application, the target usage strategy may include at least one usage condition that the target vehicle should meet to communicate with other communication devices based on any of the above-mentioned identifiers. When the target vehicle determines that itself or other communication devices meet the corresponding usage conditions, Other communication devices can be used as authorized communication objects of the target vehicle, and the target vehicle can communicate with other communication devices based on the corresponding identification.

Exemplarily, for the management identity identifier, the at least one usage condition may include, for example: receiving a request message from another communication device that satisfies the first preset condition, where the request message is used to request to obtain the identity information of the target vehicle; Or, at least one of the vehicle type, service type, vehicle status, and vehicle location of the target vehicle satisfies the second preset condition; when the target vehicle satisfies any of the above conditions, the target vehicle may communicate with other communication devices based on the management identity. communication. Exemplarily, for the permanent identity identifier, the at least one usage condition may include, for example, not sending, or sending to other communication devices that satisfy a specific authorized communication condition. Exemplarily, for the temporary identity, the at least one usage condition may include, for example, carrying the temporary identity in the periodically broadcasted BSM message. Hereinafter, detailed description will be given in conjunction with the embodiments in the vehicle operation and maintenance phases, and details will not be described here for the time being.

In the embodiment of the present application, the target usage policy may also indicate a message carrying a management identity, and the message may be a message extended for transmitting the management identity of the target vehicle, or may be a message specified by an existing relevant communication protocol, such as BSM information. The target usage policy may also indicate the frame structure of the message carrying the management identity.

For an extended message, the target usage policy may indicate each message element in the frame structure of the message; for a message specified by a relevant communication protocol, the target usage policy may include the newly added information in the frame structure of the message for carrying A message cell that manages identities. Optionally, the target usage policy may include other relevant information added in the frame structure of the corresponding message and used to realize intelligent management of the target vehicle.

Exemplarily, the management ID may be included in a BSM message sent by the target vehicle, and the BSM message may include a newly added first field and a second field, where the first field is used to carry the management ID, the The second field is used to indicate the type of the management identity. Exemplarily, the BSM message further includes a third field, where the third field is used to carry vehicle type indication information and service type indication information. Other communication devices can make corresponding actions to the target vehicle according to the vehicle type indication information and the service type indication information. For example, other vehicles decide whether to give way to the target vehicle according to the received vehicle type indication information and service type indication information of the target vehicle, so as to provide good road conditions for the target vehicle. Hereinafter, detailed description will be given in conjunction with the embodiments in the vehicle operation and maintenance phases, and details will not be described here for the time being.

Vehicle operation and maintenance phase

After the target vehicle completes the above vehicle identity registration, it can enter the vehicle operation and maintenance phase. In the vehicle operation and maintenance stage, the target vehicle can communicate with other communication devices based on the saved target algorithm and target usage strategy using the management ID, so that other communication devices can identify the target vehicle and help the vehicle management device to realize the target vehicle. monitoring and management.

Referring to Fig. 5, in the vehicle operation and maintenance stage, the vehicle management method may include the following steps:

S501: The second communication device 1-2 obtains the management identity of the target vehicle according to the saved target algorithm and the permanent identity of the target vehicle.

S502: The second communication device 1-2 sends the management identity to the third communication device 1-3 according to the stored target usage policy.

S503: The third communication device 1-3 receives the management identification of the target vehicle, and analyzes the management identification according to the target algorithm to obtain the permanent identification of the target vehicle.

S504: The third communication device 1-3 manages the target vehicle according to the permanent identification of the target vehicle.

In this embodiment of the present application, the second communication device 1-2 may be integrated in the target vehicle, may be the target vehicle itself, or may be a component or chip in the target vehicle. The third communication device 1-3 may be other communication devices in the communication system except the second communication device 1-2 integrated in the target vehicle, the third communication device 1-3 may be integrated in the vehicle management device, or may be integrated into the vehicle management device. In the roadside unit RSU, or integrated in other vehicles around the target vehicle.

The vehicle management device has an intelligent management function for the target vehicle. When the third communication device 1-3 is integrated in the vehicle management device, the management identity of the target vehicle can also be forwarded to the third communication device 1 through the roadside unit RSU. -3's. Usually the roadside unit RSU or other vehicles do not have the intelligent management function of the target vehicle, when the third communication device 1-3 is integrated in the roadside unit RSU or other vehicles, the third communication device 1-3 can be based on the received The management identity of the target vehicle is identified without the need for intelligent management of the target vehicle.

It should be understood that S503 and S504 in FIG. 5 only schematically represent whether the third communication device 1-3 has the function of intelligent management of the target vehicle by a dotted frame. It can be understood that when the roadside unit RSU or other vehicle is configured to have the intelligent management function for the target vehicle, some functions of the roadside unit RSU or other vehicle can be equivalent to the vehicle management device, and the implementation of related functions can be Please refer to the relevant description about the vehicle management device, which will not be repeated here. Alternatively, although the roadside unit RSU or other vehicles do not have the intelligent management function of the target vehicle, they can also make decisions according to the received information and their own actual situation and make corresponding disposals in order to realize the intelligent management function. provide help. For example, if the other communication device is another vehicle, the other vehicle may give way to the target vehicle, for example, to provide the target vehicle with good road traffic conditions. If the other communication device is the roadside unit RSU, the roadside unit RSU can report the management identity of the target vehicle to the vehicle management device, so that the vehicle management device can parse the management identity according to the saved target algorithm to reverse The identity of the target vehicle corresponding to the management ID is derived from the direction, and then the target vehicle is supervised according to the analysis result. It can be understood that the vehicle management device can save the corresponding relationship between the target algorithm and the registration information of the target vehicle, and when the vehicle management device parses the management identity identifier, it can also determine the identity of the target vehicle according to the corresponding relationship.

In the operation and maintenance stage of the target vehicle, when the management identity needs to be transmitted, in S501, the second communication device 1-2 may perform calculation according to the saved target algorithm and the permanent identity to generate the management identity of the target vehicle . Among them, in order to improve security, the generation method/update method of the management identity identifier can include the following examples, so as to avoid the generation mechanism of the management identity identifier from being intercepted and tampered with by a third party:

Example (1), the second communication device 1-2 can update the saved target algorithm according to the saved update strategy, so that the target vehicle can generate a new management identity according to the updated target algorithm.

In example (2), the target algorithm may be implemented based on a variety of algorithm parameters, and the algorithm parameters may include, for example, the aforementioned permanent ID, stored target key, random number (eg, temporary ID), and the like. Specifically, for example, the target vehicle can obtain the management identity of the target vehicle according to the saved target algorithm and the permanent identity of the target vehicle; or, according to the target algorithm, the permanent identity and the saved target key, Obtain the management identity; or, obtain the management identity according to the target algorithm, the permanent identity, the target key and the random number. The temporary identification is randomly generated according to an algorithm specified in the relevant communication protocol, and can be updated periodically (for example, every 300ms). Due to the randomness and periodic update of the temporary identity, the management identity obtained based on the temporary identity will not be easily tampered with by a third party, and the security of the management identity can be increased. It should be understood that a target key is correspondingly stored in the vehicle management device, and the target key can also be used to resolve the management identity to obtain a permanent identity.

It can be seen from the above description that the target usage policy stored in the second communication device 1-2 may include at least one usage condition that the target vehicle should meet to communicate with other communication devices based on the management identity, and the target vehicle itself or other communication devices satisfy the corresponding usage conditions. When conditions are met, the other communication device can be used as an authorized communication object of the target vehicle, and the second communication device 1-2 can send the management identity to other communication objects to realize communication with other communication devices. In addition, since the saved target usage policy may also include usage policies of other identities other than the management identities, the second communication device 1-2 may also communicate with other communication devices based on the other identities. Because when facing different authorized communication objects, the identity of the target vehicle transmitted by the two communicating parties and the transmission methods of different identities are different. For ease of understanding, the following description is combined with different examples.

Example 1: Feedback management identity in response to a request message

The at least one usage condition that should be satisfied by the target vehicle for communicating with other communication devices based on the management identity identifier may include: receiving a request message from other communication devices that satisfy the first preset condition, where the request message is used to request to obtain the target identity information of the vehicle. The first preset condition may, for example, be used to indicate a traffic facility that provides assistance for the vehicle management device to realize the management authority of the traffic management department.

Usually, the traffic management department will determine some more important traffic areas in the road, such as urban road entrances and exits, highway entrances and exits, toll stations, traffic/security checkpoints and other traffic checkpoints, and set up traffic facilities (such as road and road) in these traffic areas. side unit RSU), the vehicle management device obtains the identity information of passing vehicles in real time by means of the roadside unit RSU, so as to provide assistance to the traffic flow monitoring control, public security management control, etc. executed by the vehicle management device based on the obtained relevant information of the passing vehicles . These traffic checkpoints are usually important objects for assisting traffic management and obtaining vehicle information. It is a relatively basic management requirement that the management identity of the target vehicle can be identified at each traffic checkpoint.

In this case, the vehicle management device and/or the roadside unit RSU are other communication devices that satisfy the first preset condition, and when the target vehicle receives the request message from the vehicle management device and/or the roadside unit RSU, it needs to Feedback its own management identity, so that the vehicle management device and/or the roadside unit RSU can perform traffic flow monitoring control, public security management control, and the like.

Taking the communication among the vehicle management device, the roadside unit RSU and the target vehicle as an example, as shown in FIG. 6 , in the vehicle operation and maintenance phase, the vehicle management method may include the following steps:

S601: The vehicle management apparatus sends instruction information to the roadside unit RSU, where the instruction information is used to instruct the roadside unit RSU to broadcast a request message, where the request message is used to request to obtain the identity information of the target vehicle.

It should be noted that any passing vehicle passing through the roadside unit RSU can be used as a target vehicle. The above-mentioned instruction information may be sent by the vehicle management device to the roadside unit RSU in real time or periodically. Alternatively, the above-mentioned instruction information may also be a preset instruction sent by the vehicle management device to the roadside unit RSU and stored on the side of the roadside unit RSU, which may be used to instruct the roadside unit RSU to periodically (may be persistent) broadcast the request message . In the embodiment of the present application, the triggering mechanism of the RSU broadcast request message may be implemented in multiple ways, which is not limited in the present application.

S602: The roadside unit RSU sends the request message by broadcasting.

It should be understood that, the request message may also include, for example, the identifier of the roadside unit RSU and other message information elements required for information exchange, which is not limited in this application.

S603: After receiving the request message, any target vehicle around the roadside unit RSU, according to the saved target usage policy, responds to the request message and feeds back the management identifier to the roadside unit RSU, where the management identifier may include In the receipt message fed back by the target vehicle to the roadside unit RSU.

S604: The roadside unit RSU sends the management identity of the target vehicle to the vehicle management apparatus.

In an example, when the roadside unit RSU sends the management identity to the third communication device in response to the request message, it may also send signature information to the third communication device, where the signature information can be used for Prevent the cell information in the message from being maliciously tampered with.

Optionally, the target vehicle may also send at least one of the following contents to the roadside unit RSU in response to the request message: vehicle type indication information; service type indication information; timestamp; signature information; the location of the target vehicle information; or, state information of the target vehicle. The roadside unit RSU can recognize the identity of the target vehicle according to the received management identification. In addition, the roadside unit RSU may also send at least one of the above contents reported by the target vehicle to the vehicle management device, so that the vehicle management device can supervise the target vehicle according to the received relevant information.

Therefore, in some important traffic management areas, the vehicle management device can instruct the roadside unit RSU to broadcast a request message to request the target vehicle passing by the roadside unit RSU to feed back its own management identity and the required information for the implementation of supervision. Other information is convenient for the vehicle management device to supervise the target vehicle.

It should be understood that, in the above example 1, since the vehicle management device obtains the relevant information of the passing target vehicle in real time by means of the roadside unit RSU, it can be considered that the third communication device 1-3 is integrated with the vehicle management device and the vehicle management device. In the subsystem composed of the roadside unit RSU, or considered the third communication device 1-3 is composed of the communication device integrated in the vehicle management device and the communication device integrated in the roadside unit RSU.

It should be noted that the target vehicle in Example 1 can be any vehicle type or vehicle in any state, it can be a private vehicle, or it can be an ordinary commercial vehicle (such as a bus, a bus, a minibus, a cleaning operation vehicle, a sprinkler Work vehicles, road maintenance vehicles, etc.), can be special work vehicles (such as judicial vehicles, etc.) and the like. Under normal circumstances, when most vehicles are used as target vehicles for vehicle identity registration, the target usage policy issued by the vehicle management device to the target vehicle may include the above-mentioned request message received from other communication devices that meet the first preset condition. The strategy of feeding back the management identity is used to instruct the target vehicle to feed back the management identity in response to receiving the request message after the target vehicle enters the operation and maintenance phase. Different target vehicles can respond to the received request message according to the saved target usage policy and actual situation during the vehicle operation and maintenance phase, for example, feedback their own management identity. The target vehicle (for example, a judicial vehicle) may not respond to the request message if it is considered that it is not necessary to feed back the management identification according to the actual situation.

Example 2: Periodic Broadcast Management Identity

The at least one usage condition that should be met by the target vehicle for communicating with other communication devices based on the management identity identifier may include: at least one of the vehicle type, service type, vehicle status, and vehicle location of the target vehicle satisfies a second preset condition . The second preset condition may, for example, be used to indicate at least one of vehicle type conditions, service type conditions, vehicle state conditions, vehicle location conditions, etc. that the target vehicle periodically broadcasts the management identity to satisfy.

In practical applications, according to the application scenario or service implementation of the vehicle, the vehicle types may include but are not limited to ordinary commercial vehicles: commercial passenger vehicles (such as buses, buses, minibuses, taxis, etc.), trucks (such as freight trucks, etc.) , not limited to any load type), ordinary urban operation vehicles (such as cleaning operation vehicles, sprinkler operation vehicles, etc.), small/miniature vehicles, etc.; special operation vehicles for special tasks: judicial vehicles, fire trucks, medical ambulances, Engineering ambulance, etc. When different target vehicles are in different service scenarios as described above, the target vehicle can decide whether to periodically broadcast its own management identity according to its actual situation, so that other surrounding vehicles can identify the target vehicle and create a The favorable conditions for road traffic facilitate the realization of the service function of the target vehicle itself and the classification management of these target vehicles by the vehicle management device.

At this time, the strategy for the target vehicle to periodically broadcast the management identity may include the following implementations:

Example 2-1: The target vehicle is an ordinary commercial vehicle

For the above-mentioned ordinary commercial vehicles and ordinary urban operation vehicles, considering the convenience of traffic safety supervision, the target vehicle needs to periodically broadcast its management identity when performing the operation task, so that the third communication device 1-3 (the third communication device 1-3) The communication devices 1-3 can be integrated in other vehicles, in the roadside unit RSU or in the vehicle management device) after obtaining the management identification, and then identify the identity of the target vehicle according to the management identification.

Example 2-2: The target vehicle is a special vehicle performing a special mission

For special vehicles that provide special services, taking into account the special management of them, it is possible to decide whether to periodically broadcast their own management IDs according to the actual situation of the special vehicles themselves. Under some conditions, for example, when target vehicles such as fire trucks, medical ambulances, and engineering rescue vehicles perform special tasks, they are allowed to broadcast their own special identities by broadcasting their own management identities to facilitate other vehicles in the traffic flow. Identify the special identity of the target vehicle, and create favorable conditions for the target vehicle to pass the road as much as possible by giving way and other means. Under some conditions, for example, when the judicial vehicle performs a special task, in order to ensure the smooth implementation of the judicial task, it is not necessary to inform other communication devices of its own management identity, and the judicial vehicle does not need to periodically broadcast its own management identity, or only in When receiving the request message from the RSU, it feeds back its management identity and other required information. The roadside unit RSU may also report the current state, location, etc. of the target vehicle to the vehicle management device after receiving the management ID broadcast by the target vehicle, so that the vehicle management device can supervise the target vehicle.

It should be understood that when commercial vehicles and special vehicles do not perform corresponding tasks, they can be regarded as private vehicles. At this time, the supervision of these vehicles can be equivalent to private vehicles, and the communication between these vehicles and other communication devices can be realized based on the temporary identification, or it can be based on the management identification after receiving the request message from the roadside unit RSU. For implementation, please refer to the relevant description above in conjunction with Example 1 for details, which will not be repeated here.

It can be understood that, in this embodiment of the present application, the management identification may be an identification obtained for realizing the identification of the target vehicle and traffic management, and the management identification may be included in at least one message sent by the target vehicle to other communication devices. , any message may also include other information other than the management identity, such as vehicle type indication information, service type indication information, time stamp, location information of the target vehicle, and status information of the target vehicle, so that these The information can be provided to the vehicle management device, which supervises the target vehicle based on the received information.

In the embodiment of the present application, the management identity for transmitting the target vehicle may be an extended message, or may be a message specified by an existing relevant communication protocol, which is not limited in this application. As an example, the management identity of the target vehicle may be included in a BSM message broadcast by the target vehicle through the PC5 interface, and the BSM message may include a newly added first field and a second field, where the first field is used to carry the management identity, the second field is used to indicate the type of the management identity. For example:

(1) Managed ID type indication information (Managed ID type): the size of this field can be, for example, 2 bits (bit), and the value of this field can be, for example, "10", which is used to indicate that there is a management ID in the message. .

(2) Managed ID: The size of this field may be, for example, 64 bits, and the value of this field may be "1", which is used to indicate that the message carries the management ID of the target vehicle.

Therefore, when the target vehicle needs to broadcast its own management identity to communicate with other communication devices, the target vehicle writes the above message field into the BSM message to be broadcasted, so that other communication devices that receive the BSM message can Identify the identity of the target vehicle. In the above manner, the vehicle management device can directly or indirectly (for example, through the roadside unit RSU) obtain the management identity and other information of the target vehicle, and then the vehicle management device can analyze the management identity according to the locally stored target algorithm , to determine the permanent identity mark corresponding to the management identity mark, and at the same time, according to the permanent identity mark, monitor the running track of the target vehicle, and supervise the target vehicle.

Optionally, in order to facilitate the management of commercial vehicles, a third field can be added to the BSM message broadcast by commercial vehicles, such as the "operation vehicle type" message field shown in Table 1 below (may be 8bit), the value of this message field of non-operating vehicles is 0:

Table 1

operation vehicle type:

Among them, the value-meaning of the vehicle type field is as follows: 01—M1; 02—M2; 03—M3; 04—N1; 05—N2; 06—N3; For vehicles, M represents a passenger vehicle, and different values after M and N are used to indicate different load types. The value of the service type field - the meaning is as follows: 01—long-distance passenger transportation; 02—city passenger transportation; 03—city operation vehicle, such as cleaning operation vehicle; 04—city operation vehicle, such as sprinkler operation vehicle; 05—city operation vehicle, such as road Repair cars, etc.

When a commercial vehicle runs and broadcasts its own management identity, other surrounding vehicles or roadside units RSU can receive its BSM message containing the management identity of this type of vehicle. Since the BSM message will have a "operation type" field to indicate more related services provided by this type of vehicle, such as a sprinkler truck for watering, other vehicles can prompt the driver to pay attention to yield according to the received BSM message, etc. . It should be understood that the above-mentioned service types and service methods may be defined by the traffic management department and the car company, which is not limited in this application.
