Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The embodiment of the invention provides a vehicle remote control method which is mainly realized on the basis of a vehicle body control module on a vehicle, wherein a remote control instruction is sent to a communication module on the vehicle by a terminal and is sent to the vehicle body control module by the communication module to execute corresponding operation. As shown in FIG. 1, the method implemented based on the vehicle body control module comprises the following steps:
101. the vehicle body control module of the vehicle receives a control instruction sent by a terminal in a remote mode, and the control instruction comprises an unlocking instruction and a starting permission instruction.
A driver sends a remote control command to a vehicle through a terminal such as a mobile phone, wherein the remote control command comprises an unlocking command for unlocking a vehicle door and a starting permission command for indicating the vehicle to enter a starting standby mode. And after receiving the unlocking instruction and the starting permission instruction, the communication module on the vehicle sends the unlocking instruction and the starting permission instruction to the vehicle body control module for execution.
In practical applications, the terminal and the vehicle communication module interact with each other in a wireless communication manner, which includes but is not limited to using the following networks or technologies: mobile operator networks (including GSM, 3G, 4G, LTE, etc.), the internet, local area networks (WIFI or VPN, etc.), bluetooth, infrared, Near Field Communication (NFC). In some special scenarios, it is also not excluded that the terminal and the vehicle communication module interact in a wired manner, for example, through USB data lines or internet communications, and the present embodiment does not specifically limit the communication manner between the terminal and the vehicle.
In this embodiment, the terminal does not directly transmit the start instruction to the vehicle, but transmits the start permission instruction instead. The start permission instruction is for instructing the vehicle to enter a start standby mode. The start standby mode is a state in which the vehicle is not directly started but the driver is allowed to start the vehicle by activating the start switch.
102. Unlocking the vehicle door and entering a starting standby mode.
After receiving the control command sent by the communication module, the vehicle body control module unlocks the vehicle door according to the unlocking command and enters a starting standby mode according to the starting permission command. In the start-up standby mode, the vehicle is still in an un-started state, waiting for the driver to trigger the start switch. The start switch is typically located inside the vehicle, such as the "one-touch-off" key of the prior art. In this embodiment, require the driver to trigger the starting switch and start the vehicle, can effectively guarantee that the vehicle starts under the manned state, compare with the long-range vehicle that starts among the prior art, can prevent that the vehicle is in the starting state for a long time under unmanned state to prevent meaningless energy loss. For the traditional energy automobile, the consumption of fuel oil or natural gas can be reduced, and harmful gas generated by the automobile in idling can be reduced; for the electric automobile, the precious electric quantity wasted due to the fact that the automobile is in a power-on state for a long time can be prevented.
In this embodiment, the vehicle in the start-standby mode does not wait for the triggering of the start instruction indefinitely, but defines a preset time period, and the starting timing of the preset time period may be set as the time when the vehicle enters the start-standby mode, that is, the vehicle starts timing from the time when the vehicle enters the start-standby mode, and waits for the driver to enter the vehicle for triggering the start switch within the preset time period.
In practical application, the preset time length can be set according to actual requirements, for example, the preset time length is set to 30 seconds, 60 seconds, 1 minute, 5 minutes and the like, but in order to reduce the risk of vehicle theft and robbery by lawless persons, the preset time length is not set to be too long, and is generally set to be no more than 5 hours.
In addition, for the setting of the preset duration, the vehicle manufacturer can preset the preset duration before the vehicle leaves the factory, or a preset interface for setting the duration can be provided for the driver in an interactive system of the vehicle, and the driver can set the duration according to the self requirement. In an implementation manner of the embodiment of the present invention, the driver may further set the preset duration based on the APP of the terminal, and when the start permission instruction is sent to the vehicle through the terminal, the preset duration parameter is carried in the start permission instruction and sent, and the vehicle body control module configures the preset duration of the current vehicle start accordingly.
After entering the start standby mode, the vehicle body control module starts timing, if a start instruction generated by triggering a start switch is received before timing is ended, step 103 is executed, and if the start instruction is not received after timing is ended, step 104 is executed.
103. And within the preset time length after entering the starting and standby mode, if a starting instruction generated by triggering the starting switch is received, starting the vehicle.
If the driver triggers the starting switch within the preset time, the starting behavior is considered to be effective, and the vehicle body control module starts the vehicle.
104. And if the starting instruction is not received within the preset time length, refusing to start the vehicle when the starting instruction is received after the preset time length is up.
If the driver does not trigger the start switch within a preset time period and then triggers the start switch, the start behavior is considered invalid and the body control module refuses to start the vehicle.
The advantage of setting the preset duration is that the driver is only allowed to start the vehicle within a certain time frame, and if the vehicle is not started for a long time after unlocking, the driver is no longer allowed to start the vehicle by the start switch. The longer the vehicle is in the unlocked state, the higher the possibility that the vehicle is concerned and stolen by a lawless person is, so the embodiment of the invention can effectively reduce the risk that the vehicle is stolen and robbed by setting the starting time limit.
In practical applications, there may be the following: the driver starts the vehicle within a preset time length, and after driving for a period of time, the vehicle is shut down, and then the vehicle needs to be restarted for driving. For this case, the embodiments of the present invention provide several solutions as follows:
1. the looser mechanism is that after the driver legally starts the vehicle for the first time, the driver is defaulted to be a legal driver, and the subsequent vehicle operation behaviors are all triggered by the legal driver. Therefore, the vehicle can be started for an unlimited number of times after being shut down, the vehicle does not enter a starting standby mode any more when being subsequently started, the starting standby mode is not limited by preset duration, and a driver can start the vehicle through the starting switch at any time. The scheme has the advantages that interactive communication between the vehicle and the terminal due to repeated starting can be reduced, communication resource consumption is reduced, and the use by a driver is facilitated.
2. A relatively prudent mechanism is to default to a legitimate driver when the driver has first legally started the vehicle, but not to determine whether subsequent vehicle operation activities are still triggered by the legitimate driver. Therefore, the vehicle can be started for a limited number of times after being shut down, the vehicle can be started within the preset starting limit number of times without entering a starting standby mode, the starting is not limited by the preset duration, and a driver can start the vehicle through the starting switch at any time. When the number of times of start-up is exceeded, if the vehicle needs to be started up again, the terminal is required to resend the start-up permission instruction and repeat the flow shown in fig. 1 described above. The scheme has the advantages that under the condition that whether the driver is always a legal driver or not is uncertain, the safety of the vehicle is considered due to the consideration of convenience and rapidness of operation, limited times of 'simplified' operation are provided for the driver, even if the vehicle is subsequently stolen and robbed by lawbreakers under the condition that the legal driver leaves, the lawbreakers cannot start the vehicle through the starting switch after using the vehicle for limited times, and therefore convenience is brought to vehicle owners to find the vehicle.
3. A more discreet mechanism is to determine that the operational behaviour is legitimate when the driver has first legitimately started the vehicle and to default to a subsequently generated operational behaviour being unauthorised. In this case, if the vehicle needs to be started, the terminal must obtain the authorization again, that is, the terminal needs to resend the start permission instruction and repeat the flow shown in fig. 1. The advantage of this solution is that the risk of vehicle theft can be minimized.
An application scenario of the embodiment of the present invention is given below, in which the owner a borrows the vehicle for use by the friend B, but since the owner a is unwilling or inconvenient (e.g., the person is out of the country) to hand the vehicle key to the friend B, the solution provided by the embodiment can be used. Specifically, when the A and the B determine that the B reaches the vehicle parking position through communication means such as telephone, short message and the like, the A remotely sends an unlocking instruction and a starting permission instruction to the vehicle through a mobile phone, and the vehicle unlocks a vehicle door and enters a starting standby mode. At the moment, B enters the vehicle and manually triggers a 'one-key start-stop' key, and the vehicle detects that the starting instruction is triggered within a preset time length, so that the vehicle is started. And B, triggering the 'one-key start-stop' key again to flameout the vehicle after the vehicle is used, and not making triggering time limit requirements on the flameout instruction vehicle. And B, automatically locking the vehicle after leaving the vehicle, or remotely controlling the vehicle to be locked by the A through a mobile phone after the B calls the A.
According to the scene, the embodiment of the invention can complete the handover and the use of the vehicle under the condition that the A and the B do not meet the surface, and meanwhile, because the time limit requirement for starting the vehicle is set, lawless persons can be prevented from stealing and robbing the vehicle at random, and the safety of the vehicle in the borrowing state is ensured.
In another application scenario of this embodiment, fleet organizations such as public transport companies can implement fine scheduling of vehicles and people by means of remote authorized starting of terminals, thereby improving management efficiency. For a car rental company, fine-grained rental service of 'pay-per-view' can be provided for a user by means of remote authorization of the starting times of the terminal, and the service types of a car rental market are enriched. For the enterprises and public institutions, the superior can effectively control the vehicle use authority of the personnel of the enterprises and public institutions by means of remote authorized starting through the terminal, so that the phenomenon of private use of the public vehicles is prevented.
Further, as a supplement to the above method, an embodiment of the present invention further provides a method for remotely controlling a vehicle, as shown in fig. 2, the method including:
201. the vehicle body control module receives a control instruction which is sent by the communication module in an encryption mode through a first encryption algorithm.
And the communication module is communicated with the terminal through a wireless network outside the vehicle and receives a control instruction sent by the terminal remotely. And in the vehicle, the communication module is communicated with the vehicle body control module through a CAN bus and sends a control instruction to the vehicle body control module.
In order to prevent a hacker from invading the interior of a vehicle to steal a control instruction transmitted on a CAN bus, or forge the control instruction and send the forged control instruction to a vehicle body control module through invading the CAN bus, the control instruction transmitted on the CAN bus is encrypted and sent through a first encryption algorithm. Specifically, after receiving a control instruction sent by a terminal, the communication module encrypts the control instruction through a first encryption algorithm, and then sends the encrypted control instruction to the vehicle body control module through the CAN bus. And the vehicle body control module decrypts the control command by using a first encryption algorithm after receiving the control command, obtains the decrypted control command and executes the decrypted control command.
In practical application, a symmetric encryption algorithm or an asymmetric encryption algorithm can be adopted for encrypting the control command. For the former algorithm, the communication module and the vehicle body control module use the same secret key for encryption and decryption; for the latter algorithm, the communication module can use the public key to encrypt and the vehicle body control module can use the private key to decrypt, or the communication module can use the private key to encrypt and the vehicle body control module can use the public key to decrypt. The embodiment does not limit the encryption algorithm to be specifically adopted.
In addition, the control instruction sent by encryption in this embodiment may further include various control instructions transmitted through a CAN bus inside the vehicle, in addition to the remote control instruction such as the unlock instruction and the start permission instruction sent by the terminal, and in a more reliable implementation, all data information transmitted between the communication module and the vehicle body control module may be encrypted and transmitted.
202. The vehicle body control module decrypts the control command by using a first encryption algorithm.
If the decryption is successful, step 203 is performed, otherwise step 204 is performed.
203. And if the decryption is successful, the vehicle body control module executes the operation corresponding to the control instruction.
Specifically, in this embodiment, after the decryption is successful, the body control module executes step 205.
204. And if the decryption fails, the vehicle body control module discards the control instruction.
Further, in an implementation manner of this embodiment, if the control instruction received by the communication module is a control instruction encrypted by the terminal using the second encryption algorithm, before the communication module encrypts and transmits the control instruction using the first encryption algorithm, the communication module needs to decrypt the control instruction encrypted and transmitted by the terminal using the second encryption algorithm, and then encrypt and transmit the decrypted control instruction using the first encryption algorithm.
In practical application, the second encryption algorithm can be used for encrypting data transmitted between the terminal and the communication module, when the terminal and the communication module perform instruction encryption transmission, the control instruction received by the communication module is encrypted by the terminal through the second encryption algorithm, and in this case, the control instruction needs to be decrypted firstly based on the second encryption algorithm and then encrypted by using the first encryption algorithm.
Similar to the first encryption algorithm, the second encryption algorithm may also adopt a symmetric encryption algorithm or an asymmetric encryption algorithm in practical applications, and the key usage manner thereof is the same as the key usage manner described above and is not described herein again.
The remote control method provided by the embodiment can carry out encryption transmission on the control command transmitted inside the vehicle, and prevent hackers from cracking or forging the control command. In addition, when the encryption transmission is carried out between the terminal and the communication module, the command safety protection between the outside of the vehicle and the inside of the vehicle can be realized, so that the complete and effective safety protection can be carried out on the transmission link between the terminal and the vehicle body control module, and the safety level of remote control is further improved.
Furthermore, in an implementation manner of the embodiment of the present invention, in order to increase the difficulty of cracking or forging the control command by a hacker, different encryption algorithms may be used to encrypt links from the terminal to the communication module and links from the communication module to the vehicle body control module, respectively, that is, it is ensured that the first encryption algorithm is different from the second encryption algorithm in the encryption algorithm. For example, a symmetric encryption algorithm may be used for encryption from the terminal to the communication module, an asymmetric encryption algorithm may be used for encryption from the communication module to the vehicle body control module, or vice versa; or, when both of them use a symmetric encryption algorithm or an asymmetric encryption algorithm, different types of encryption algorithms are used for encryption, for example, when both of them use a symmetric encryption algorithm, one link may use a DES algorithm, and the other link may use an RC2 algorithm; or when asymmetric encryption algorithms are used, one link may use the RSA algorithm and the other link may use the Diffie-Hellman algorithm.
As mentioned above, in a more conservative implementation, all data information transmitted between the communication module and the vehicle body control module may be encrypted. However, in practical applications, the data encryption and decryption process consumes time and system processing resources, and especially when an asymmetric encryption algorithm is adopted, the time consumed for encryption and decryption may even be more than 1000 times that consumed by a symmetric encryption algorithm, so in an implementation manner of this embodiment, it may be considered that the communication module encrypts the control instruction of the preset category by using the first encryption algorithm, that is, encrypts and transmits part of the data information, and transmits the rest of the data information in a plaintext manner. In principle, important control commands are selected for encrypted transmission, and the important control commands are generally control commands related to vehicle use authority and vehicle safety. In this embodiment, the following control instructions may be sent in an encrypted manner: an unlock/close door command, a vehicle start/stop command, and a start permission command.
205. The vehicle body control module unlocks the vehicle door and enters a starting standby mode.
206. And in a preset time length after entering the starting and standby mode, if a starting instruction generated by triggering the starting switch is received, the vehicle body control module starts the vehicle.
As a perfect way of implementing this step, besides receiving the start instruction within the preset time, the vehicle body control module needs to detect whether the brake pedal is stepped down when the start instruction is triggered, and only when the two conditions are met simultaneously, the vehicle body control module will start the vehicle. The mode has the advantages that on one hand, when the vehicle is started, the brake pedal is stepped down, so that the vehicle can be prevented from moving out of control in a gear engaging state, and the driving safety of the vehicle can be improved; on the other hand, when the vehicle is started, the brake pedal is pressed down, so that the vehicle is further ensured to be started under the condition of manned driving, and the vehicle is prevented from being stolen or energy loss.
207. If the starting instruction is not received within the preset time length, the vehicle body control module refuses to start the vehicle when the starting instruction is received after the preset time length is up.
Further, as a refinement to this step, it is also necessary to consider how to provide a remedial mechanism for the driver after the body control module refuses to start the vehicle. In one implementation manner of the embodiment, when the driver does not start the vehicle within the preset time period, the vehicle key can be used for manually starting the vehicle, and the vehicle body control module starts the vehicle in a conventional manner when receiving a starting instruction triggered by the insertion of the vehicle key. This way it is ensured that the vehicle owner, or the legitimate user of the vehicle key, can eventually successfully start the vehicle.
In another implementation manner of the embodiment, when the driver does not start the vehicle within the preset time period, the start permission instruction may be remotely sent to the vehicle again through the terminal, and the start switch is triggered within the reset preset time period. For example, when the friend B of the vehicle owner a does not start the vehicle in time, the friend B can inform the friend a of sending the start permission instruction again through the mobile phone by telephone, and the vehicle body control module reenters the start standby mode when receiving the start permission instruction sent by the terminal remotely again, and repeats the step 206 or the step 207 to wait for the friend B to start the vehicle.
Further, as an implementation of the method, the embodiment of the invention further provides a device for remotely controlling the vehicle, wherein the device is located in the vehicle body control module. As shown in fig. 3, the apparatus includes:
a receiving unit 31, configured to receive a control instruction sent by a terminal remotely, where the control instruction includes an unlocking instruction and a start permission instruction;
a processing unit 32 for unlocking the vehicle door and entering a start-up standby mode;
the execution unit 33 is configured to start the vehicle if a start instruction generated by triggering the start switch is received within a preset time period after entering the start-standby mode, where the start switch is disposed in the vehicle;
the execution unit 33 is further configured to refuse to start the vehicle when the start instruction is received after the preset time period expires if the start instruction is not received within the preset time period.
Further, the execution unit 33 is configured to start the vehicle if it is detected that the brake pedal is pressed while receiving the start instruction.
Further, the execution unit 33 is configured to start the vehicle if a start instruction triggered by inserting a vehicle key is received after the preset time period expires.
Further, the processing unit 32 is configured to, after the preset duration expires, re-enter the startup standby mode if the receiving unit 31 receives the startup permission instruction sent by the terminal remotely again.
Further, after the vehicle is started, if the vehicle needs to be restarted after the preset time period is exceeded, then:
the execution unit 33 is used for starting the vehicle after receiving a starting instruction generated by triggering the starting switch;
the execution unit 33 is configured to start the vehicle after receiving a start instruction generated by triggering the start switch within a preset number of times, otherwise, the receiving unit 31 waits for receiving a start permission instruction and reenters the start standby mode through the processing unit 32;
