< general concept >
The general concept of the present embodiment is to provide a new vehicle control method:
the server generates authorization information of the target vehicle, wherein the authorization information of the target vehicle comprises identity information of the target vehicle and first authority information, the first authority information is obtained by encrypting second authority information by the server through a management key of the target vehicle, and the second authority information is used for appointing vehicle control authority.
The server sends the authorization information of the target vehicle to the terminal, and the terminal sends the first authority information to the target vehicle in a short-distance wireless communication mode according to the identity information of the target vehicle.
The target vehicle decrypts the first right information using the management key of the target vehicle to obtain the second right information.
The vehicle management device is arranged on the body of the target vehicle and is powered by a battery, when the battery power is too low, the long-distance wireless communication function of the vehicle management device cannot work normally, and the short-distance wireless communication module of the vehicle management device can still be used normally.
Or, the target vehicle is parked in a no-signal area, the target vehicle cannot communicate with the server, and the short-range wireless function of the target vehicle is normal.
Therefore, when the terminal is in the signal area, the terminal can perform long-distance wireless communication with the server, and acquire the authorization information of the target vehicle from the server in advance. And then, in the vicinity of the target vehicle, the authorization information is forwarded to the target vehicle based on the short-range wireless communication mode. The target vehicle decrypts the authorization information of the target vehicle through the vehicle management key stored in advance so as to obtain the second authority information, so that the user can still control the vehicle.
In addition, the vehicle control authority is encrypted by the server using the management key of the target vehicle, and only the server and the target vehicle know the management key of the target vehicle, and the terminal does not know the management key of the target vehicle. The terminal plays a forwarding role in the vehicle control method provided by the application so as to forward the first authority information of the target vehicle to the target vehicle, and when the target vehicle acquires the first authority information, the first authority information is decrypted according to a management key of the target vehicle stored by the terminal, so that the vehicle control authority information is acquired. Since the terminal does not know the management key of the target vehicle all the time, the safety of the whole control process is ensured.
< example >
The vehicle control method provided by the embodiment of the disclosure, as shown in fig. 1, includes the following steps S101 to S103:
s101, the server generates authorization information of the target vehicle, wherein the authorization information of the target vehicle comprises identity information of the target vehicle and first authority information, the first authority information is obtained by encrypting second authority information by the server through a management key of the target vehicle, and the second authority information is used for appointing vehicle control authority.
Specifically, when the server is in long-distance wireless connection with the terminal equipment, the terminal sends a vehicle application request to the server. The above request for applying for a vehicle includes, for example: location information of the terminal and a terminal identification. Of course, other information may be included, such as the type of usable vehicle that the request is intended to use.
And when receiving a vehicle application request sent by the terminal, the server reads the position information and the terminal identification of the terminal from the vehicle application request and selects a target vehicle for the terminal based on the position information and the terminal identification. Optionally, the server selects a vehicle closest to the terminal as the target vehicle according to the position information of the terminal. Optionally, in order to meet the personalized requirements of the user, the server may also recommend a plurality of vehicles for the user based on a vehicle application request sent by the terminal, and the user specifies a target vehicle.
And after the server selects the target vehicle, generating the authorization information of the target vehicle based on the identity information of the target vehicle and the second authority information. The identification information of the target vehicle may be a MAC address, an ID, or a serial number of the target vehicle. Optionally, the vehicle control authority specified by the second authority information includes an unlocking control authority. Further optionally, the vehicle control authority specified by the second authority information includes any one of a lock control authority, a window control authority, a vehicle lamp control authority, and a whistle control authority, or any combination thereof. Further, the vehicle control authority specified by the second authority information may also be a vehicle control authority requested by the terminal.
S102, the server sends the authorization information of the target vehicle to the terminal, and the terminal sends the first authority information to the target vehicle in a short-distance wireless communication mode according to the identity information of the target vehicle.
When the terminal in S102 transmits the first authority information to the target vehicle by the short-range wireless communication method based on the identification information of the target vehicle, the target vehicle is in a state of being unable to communicate with the server, and the terminal is in a state of being able to or unable to communicate with the server.
Specifically, when the server is in remote wireless connection with the terminal device, the server sends the authorization information of the target vehicle to the terminal. And the terminal reads the identity information of the target vehicle in the target vehicle authorization information. When the terminal is near the target vehicle, the terminal identifies the target vehicle based on the identity information of the target vehicle, establishes connection with the identified target vehicle in a short-distance wireless communication mode, and sends the first authority information to the target vehicle. At this time, the target vehicle is in a state of being unable to communicate with the server, and the terminal process is in a state of being able to or unable to communicate with the server.
The terminal establishes connection with the identified target vehicle in a near field communication mode, and sends the first authority information to the target vehicle. For example, it may be: and the Bluetooth module of the terminal searches for the Bluetooth module with the same MAC address according to the MAC address of the target vehicle and performs pairing connection with the Bluetooth module. After the terminal is connected with the target vehicle, the terminal sends first authority information in the authorization information of the target vehicle to the target vehicle.
Optionally, the short-range wireless communication mode may be bluetooth, WIFI, or NFC.
It should be noted that, since the first authority information is encrypted by the server using the management key of the target vehicle, and only the server and the target vehicle hold the management key of the target vehicle, the terminal cannot read the second authority information for specifying the vehicle control authority included in the first authority information, which can prevent the user from maliciously tampering with the control authority of the target vehicle. Meanwhile, even if the first authority information sent to the target vehicle by the terminal is intercepted maliciously, the control authority of the target vehicle cannot be revealed.
S103, the target vehicle decrypts the first authority information by using the management key of the target vehicle to obtain second authority information.
Specifically, since the vehicle stores the management key of the target vehicle in advance, after the target vehicle receives the first authorization information, the target vehicle can decrypt the first authorization information according to the management key of the target vehicle, so as to obtain the second authorization information.
In the vehicle control method provided by the present disclosure, the terminal and the server acquire the authorization information of the target vehicle in advance when the remote wireless communication is possible. If the electric quantity of the target vehicle is too low to support the target vehicle to carry out long-distance wireless communication with the server, when the user carries the terminal to reach the vicinity of the target vehicle, the target vehicle is in a state of being incapable of communicating with the server. Or the target vehicle is parked in a no-signal area, and when the user carries the terminal to reach the vicinity of the target vehicle, the terminal and the target vehicle cannot communicate with the server. At this time, the terminal forwards the authorization information of the target vehicle acquired in advance to the target vehicle in a short-distance wireless communication mode. The target vehicle decrypts the authorization information of the target vehicle through the pre-stored management key so as to obtain the second authority information, so that the user can still use the vehicle.
In addition, the vehicle control authority is encrypted by the server using the management key of the target vehicle, and only the server and the target vehicle know the management key of the target vehicle, and the terminal does not know the management key of the target vehicle. The terminal plays a forwarding role in the vehicle control method provided by the application so as to forward the first authority information of the target vehicle to the target vehicle, and when the target vehicle acquires the first authority information, the first authority information is decrypted according to a management key of the target vehicle stored by the terminal, so that the vehicle control authority information is acquired. Since the terminal does not know the management key of the target vehicle all the time, the safety of the whole control process is ensured.
In a first optional embodiment, when the vehicle control authority specified by the second authority information only includes one control authority, such as an unlocking control authority, after the target vehicle executes the above S103 to obtain the second authority information, the target vehicle may directly control the target vehicle to execute an unlocking action. Therefore, when the shared vehicle is parked in the no-signal area, by using the vehicle control method provided by the embodiment, when the vehicle is parked in the no-signal area, or the electric quantity of the vehicle is too low to support the target vehicle to perform long-distance wireless connection with the server, the terminal device can still unlock the target vehicle.
In a second alternative embodiment, in order to meet the user's personalized needs, whether the target vehicle executes the vehicle control authority may be controlled by the user. Based on this, on the basis of any one of the above embodiments, the vehicle control method provided by the present disclosure further includes the following S104-S107:
and S104, after the target vehicle obtains the second authority information, sending the second authority information to the terminal.
When the target vehicle transmits the second authority information to the terminal, the second authority information is still transmitted by the near-field communication method.
And S105, after the terminal receives the second authority information from the target vehicle, providing buttons corresponding to the vehicle control authorities specified by the second authority information one by one on an interface of the terminal.
And S106, the terminal sends a vehicle control command corresponding to the triggered button to the target vehicle according to the operation triggered by the user on the button.
And S107, after the target vehicle receives the vehicle control command, operating the target vehicle to execute the action corresponding to the vehicle control command.
Illustratively, when the user clicks the whistle control button, the terminal sends a whistle command to the target vehicle. When the target vehicle receives the command, a whistle operation is performed. It should be noted that when the user clicks the whistle control button, the target vehicle whistle can help the user to find the target vehicle faster.
In a third optional embodiment, based on the second embodiment, in order to further avoid malicious tampering of the control authority of the target vehicle by an illegal user, after the target vehicle receives the vehicle control command sent by the terminal, it needs to verify whether the vehicle control command is within the control authority specified by the second authority information. Based on this, S107 specifically includes the following S1071 and S1072:
s1071, after the target vehicle receives the vehicle control command, determining whether the vehicle control command is in the vehicle control authority specified by the second authority information.
S1072, if the vehicle control command is in the vehicle control authority specified by the second authority information, the operation target vehicle executes the action corresponding to the vehicle control command.
Specifically, after receiving the vehicle control command, the target vehicle verifies the control command with the vehicle control authority specified by the second authority information. If the vehicle control command is within the vehicle control authority specified by the second authority information, the verification is successful. And after the verification is successful, the target vehicle executes the action corresponding to the vehicle control command.
In a fourth alternative embodiment, the situation that the target vehicle is occupied but not utilized due to the fact that the user does not send the vehicle control command to the target vehicle for a long time after obtaining the vehicle control authority of the target vehicle is avoided. Or, when the target vehicle sends the second authority information to the user terminal and the second authority information is intercepted by the illegal user terminal, the risk that the illegal user terminal controls the target vehicle is reduced. The second authority information is also used to specify the effective time of the vehicle control authority.
Based on this, S107 specifically includes the following S1073 to S1075:
s1073, after the target vehicle receives the vehicle control command, determining whether the vehicle control command is in the vehicle control authority specified by the second authority information.
S1074, if the vehicle control command is in the vehicle control authority specified by the second authority information, determining whether the current time is in the valid time of the vehicle control authority corresponding to the control command.
S1075, if the current time is within the valid time of the vehicle control authority corresponding to the control command, the control target vehicle executes the action corresponding to the vehicle control command.
For example, when the vehicle control command received by the target vehicle is an unlocking command, the target vehicle determines whether the vehicle control authority specified by the previously acquired second authority information includes an unlocking control authority, and if not, the target vehicle does not execute an unlocking action. If yes, further judging and determining whether the current time is within the valid time of the unlocking control authority corresponding to the unlocking command.
For example, when the target vehicle sends the unlocking control authority to the terminal, the current time of the target vehicle is 12:10, and the effective time of the unlocking control authority is 20 minutes. Then when the target vehicle is at 12: and 30, when an unlocking command sent by the terminal is received before, the target vehicle executes the vehicle unlocking action. At 12: after 30 hours, the target vehicle does not perform the unlocking operation even if it receives the unlocking command transmitted from the terminal.
For another example, when the target vehicle sends the unlocking control authority to the terminal, the effective time of the unlocking control authority is 12:10-12:30 in 12 months and 1 day in 2018. The target vehicle executes the vehicle unlocking action when the target vehicle receives the unlocking command sent by the terminal in 12:10-12: 30. When the target vehicle receives the unlocking command sent by the terminal, the unlocking command is not within 12:10-12:30, and the unlocking action cannot be executed even if the unlocking command sent by the terminal is received.
It should be noted that different vehicle control authorities may correspond to different valid times.
Based on the embodiment, the situation that the target vehicle is occupied but not utilized due to the fact that the user does not send the vehicle control command to the target vehicle for a long time after obtaining the vehicle control authority of the target vehicle can be avoided, and therefore the utilization rate of the vehicle can be improved. In addition, even if the second authority information of the target vehicle is intercepted by the illegal user terminal, the illegal user terminal can only control the target vehicle within the effective time of the vehicle control authority, so that the safety of the whole control process can be improved.
In a fifth optional embodiment, in order to ensure the security of information interaction between the terminal and the target vehicle, on the basis of any one of the above embodiments, the authorization information of the target vehicle further includes a first session key and a second session key, and the first session key is obtained by the server by encrypting the second session key using the management key of the target vehicle. Based on this, the vehicle control method provided by the present disclosure further includes the following S108-S110:
and S108, the terminal forwards the first session key to the target vehicle in a short-distance wireless communication mode.
S109, the target vehicle decrypts the first session key by using the management key of the target vehicle to obtain a second session key.
And S110, in the subsequent short-distance wireless communication process of the terminal and the target vehicle, the sender uses the second session key to encrypt the sent information, and the receiver uses the second session key to decrypt the received information.
For example, the example that the target vehicle sends the second permission information to the terminal and the terminal sends the vehicle control command to the target vehicle is taken as an example, the above S108 to S110:
when the terminal acquires the authorization information of the target vehicle from the server, the identity information of the target vehicle and the second session key which are not encrypted can be directly read from the authorization information.
And the terminal directly forwards the first session key and the first authority information to the target vehicle in a short-distance wireless communication mode according to the identity information of the target vehicle.
And the target vehicle receives the first session key and the first authority information, decrypts the first session key and the first authority information by using the vehicle management key stored by the target vehicle, and obtains a second session key and second authority information.
In the subsequent short-distance wireless communication process, the sender uses the second session key to encrypt the sent information, and the receiver uses the second session key to decrypt the received information. For example, the target vehicle serves as a sender, and the second right information is encrypted using the second session key when the second right information is sent to the terminal. And then, the target vehicle sends the encrypted second authority information to the terminal. And the terminal is used as a receiver and decrypts by using the second session key after receiving the encrypted second authority information to obtain the second authority information.
Exemplarily, as shown in fig. 3, the vehicle control method provided by the present disclosure is described in conjunction with the fifth alternative embodiment, the embodiment shown in fig. 1, and the second alternative embodiment. Specifically, the method comprises the following steps:
when the terminal is in long-distance wireless communication with the server, the terminal applies for a vehicle request to the server, and when the server receives the vehicle application request sent by the terminal, the server generates authorization information of a target vehicle and sends the authorization information of the target vehicle to the terminal.
When the terminal and the vehicle cannot be in remote wireless communication with the server or the vehicle cannot be in remote wireless communication with the server, the terminal reads the second session key and sends the first authority information and the first session key to the target vehicle in a short-distance wireless communication mode according to the identity information of the target vehicle; the target vehicle decrypts the first authority information and the first session key by using the management key of the target vehicle to obtain second authority information and a second session key; the target vehicle encrypts the second authority information according to the second session key and sends the second authority information to the terminal; after the terminal obtains the encrypted second authority information, the terminal decrypts the encrypted second authority information according to the second session key to obtain second authority information; after the terminal obtains the second authority information, providing buttons corresponding to the vehicle control authorities specified by the second authority information one by one on an interface of the terminal; the terminal receives a vehicle control command generated by the triggering operation of the user on the button, utilizes the vehicle control command encrypted by the second session key, and finally sends the encrypted vehicle control command to the target vehicle; and after receiving the encrypted vehicle control command, the target vehicle decrypts the encrypted vehicle control command by using the second session key to obtain the vehicle control command, so that the target vehicle is controlled to execute the action corresponding to the vehicle control command.
In a sixth alternative embodiment, after the target vehicle is used, the server needs to obtain a vehicle usage report, so as to monitor the usage of the vehicle, for example, perform a fee-ending operation according to the vehicle usage report. With respect to the vehicle control method provided in any of the above embodiments, the present disclosure enables the server to obtain the usage report of the vehicle through the following steps S111 to S113:
and S111, generating a vehicle use report by the target vehicle and encrypting the vehicle use report by using the management key of the target vehicle to obtain the encrypted vehicle use report.
For example, the target vehicle generates a vehicle usage report upon detecting a deadbolt closure. The vehicle use report may include the time of opening the lock tongue, the time of closing the lock tongue, the vehicle driving route, and the like.
And S112, the target vehicle transmits the encrypted vehicle use report to the terminal through the short-distance wireless communication mode, and the terminal transmits the encrypted vehicle use report to the server.
When the target vehicle transmits the encrypted vehicle use report to the terminal by the short-range wireless communication method, the target vehicle is in a state where communication with the server is impossible, and the terminal is in a state where communication with the server is possible or impossible.
The server decrypts the encrypted vehicle usage report information using the vehicle management key of the target vehicle to acquire a vehicle usage report S113.
The target vehicle encrypts the vehicle usage report according to the management key of the target vehicle, so that the terminal can be prevented from tampering the vehicle usage report when receiving the vehicle usage report. In addition, when the user uses up the target vehicle, the target vehicle is parked in a no-signal area again, namely the target vehicle and the terminal cannot communicate with the server, or the electric quantity of the target vehicle is too low to support the target vehicle to remotely wirelessly communicate with the server, namely the target vehicle cannot communicate with the server, and the terminal can communicate with the server.
Of course, when the target vehicle is parked in the signal area, the target vehicle may perform remote wireless communication with the server, and directly transmit the vehicle use report generated by the remote wireless communication to the server. The server can quickly acquire the vehicle use report of the target vehicle.
In a seventh alternative embodiment, after the terminal establishes the short-range wireless communication connection with the target vehicle, during the communication process between the terminal and the target vehicle, the following operations are executed:
the target vehicle generates a random sequence m, for example a random number, and transmits the random sequence m to the terminal together when the target vehicle transmits the first information to the terminal.
In the subsequent process, the terminal appends the sequence p to the transmission information each time the terminal transmits information to the target vehicle; the sequence P is a random sequence m + n, the initial value of n is 1, and n is automatically added with 1 after the terminal sends information to the target vehicle once.
For example, in the subsequent process, when the terminal transmits information to the target vehicle for the first time, the sequence P is added to the transmission information as the random sequence m +1, when the terminal transmits information to the target vehicle for the second time, the sequence P is added to the transmission information as the random sequence m +2, when the terminal transmits information to the target vehicle for the third time, the sequence P is added to the transmission information as the random sequence m +3, and so on.
When the target vehicle receives the information sent by the terminal, the legality of the information can be judged according to the received sequence P and the random sequence m stored in the target vehicle, and illegal equipment is prevented from pretending to be the terminal. For example:
the sequence P of information received this time-the sequence P of information received last time is 1,
the number of times of the sequence P-message of the received information is m.
