[0060] The vehicle unlocking method provided in the embodiments of this specification will be exemplarily described below with reference to the accompanying drawings.

[0061] Exemplary Methods

[0062] like Figure 1 To solve the above technical problems, the present application provides a vehicle unlocking method, which may include the following steps:

[0063] S100: The vehicle-mounted networking terminal periodically sends a first message to the instrument, where the first message includes a vehicle signal status and a vehicle locking function activation status.

[0064] The vehicle networking terminal is electrically connected to the instrument, and the vehicle networking terminal and the instrument achieve information synchronization by sending CAN messages. Specifically, the vehicle networking terminal periodically sends messages to the instrument. We name the message sent by the vehicle networking terminal to the instrument as the first message to distinguish the message sent by the instrument to the vehicle networking terminal. According to the content of the first message, the instrument can obtain the vehicle signal status and the activation status of the vehicle locking function. The vehicle signal status can be obtained through the signal status of the vehicle networking terminal.

[0065] The signal status of the vehicle networking terminal can be intuitively reflected by its indicator light. For example, the "M" light and the "S" light indicate the working status of the GSM (Global System for Mobile Communications) part and the GPS respectively. When the "M" light flashes at different frequencies, the GPRS (general packet radio service) connection status can be judged, such as no connection, successful connection, successful network login, etc.

[0066] The activation status of the vehicle locking function can be determined by the controller. The controller will store the remote vehicle locking function activation flag in the flash memory. Each time the vehicle is powered on, the controller reads the flag status from the memory to determine whether the vehicle locking function is activated.

[0067] S200: The instrument periodically sends a second message to the vehicle networking terminal, where the second message includes the pre-embedded locking state and the remaining pre-embedded locking time.

[0068] The instrument periodically sends messages to the vehicle-mounted networking terminal. The periods for sending messages between the instrument and the vehicle-mounted networking terminal can be the same or different, and can be set according to actual conditions. We name the message sent by the instrument to the vehicle-mounted networking terminal as the second message. According to the content of the second message, the vehicle-mounted networking terminal can obtain the pre-embedded locking state and the remaining pre-embedded locking time. Among them, the pre-embedded locking state includes the activated state and the locked state. When the pre-embedded locking state is the locked state, the remaining pre-embedded locking time is the initial value of the instrument countdown; when the pre-embedded locking state is the activated state, the instrument starts the internal countdown. At this time, the gradually decreasing remaining pre-embedded locking time can be obtained from the content of the second message. The remaining pre-embedded locking time is the remaining time of the current countdown.

[0069] S300: The instrument panel or the vehicle-mounted networking terminal performs vehicle locking management according to the vehicle signal status and the reception status of the first message and the second message.

[0070] When the vehicle networking terminal is dismantled or the vehicle networking terminal parts are damaged or there is no signal in the area where the vehicle is located, the vehicle signal status will be no signal, and it will affect the reception of the first message. When the instrument is dismantled, it will affect the reception of the second message. According to the vehicle signal status and the reception of the first message and the second message, different locking methods can be selected to manage the vehicle.

[0071] In some embodiments of the present application, the vehicle-mounted networking terminal periodically sends a first message to the instrument, the first message including the vehicle signal status and the activation status of the vehicle locking function, and the instrument periodically sends a second message to the vehicle-mounted networking terminal, the second message including the pre-embedded locking machine status and the remaining pre-embedded locking machine time. By locking the vehicle according to the vehicle signal status and the reception of the first message and the second message, the instrument or the vehicle-mounted networking terminal can increase the options for unlocking the vehicle, reduce the dependence of locking the vehicle on the signal, and realize vehicle locking management in the absence of a signal.

[0072] Vehicle lock management not only involves locking the vehicle, but also unlocking the vehicle.

[0073] In some embodiments of the present application, Figure 2 As shown, in S300, the instrument or the vehicle networking terminal performs vehicle locking management according to the vehicle signal state and the reception of the first message and the second message. Specific steps may include:

[0074] S311: When the meter does not receive the first message within a first preset time, or the vehicle signal status in the first message is no signal, the meter starts an internal countdown.

[0075] The first preset time is set in advance, for example, the first preset time is set to 1 hour. When the meter cannot receive the message sent by the vehicle networking terminal, the possible situation at this time is that the vehicle networking terminal is dismantled, the wiring harness connecting the meter and the vehicle networking terminal is faulty, or the components of the vehicle networking terminal are damaged. When the meter fails to receive the first message sent by the vehicle networking terminal after the first preset time, no matter which of the above situations, the meter will start the internal countdown. When the vehicle signal status in the first message received by the meter is no signal, it is possible that there is no signal in the area where the vehicle is located. At this time, the meter will also start the internal countdown. At this time, the embedded lock state is activated, and the remaining embedded lock time gradually decreases.

[0076] S312: When the instrument countdown reaches the end of the countdown from the initial value of the instrument countdown, the instrument triggers the controller to lock the vehicle.

[0077] The initial value of the instrument countdown is pre-set. For example, the initial value of the instrument countdown can be set before leaving the factory. The initial value of the instrument countdown can be set in the range of 1 hour to 900 hours. The default setting is generally 100 hours. When the instrument countdown reaches the end of the countdown from the initial value of the instrument countdown, the instrument triggers the controller to lock the vehicle.

[0078] In addition, personnel with operation authority can go to the site and input the password at the instrument end to reset the embedded time. The embedded time is the initial value of the instrument countdown.

[0079] In some embodiments of the present application, in S311, when the meter does not receive the first message for more than the first preset time, or the vehicle signal state in the first message is no signal, the meter starts the internal countdown specific steps may also include:

[0080] When the meter does not receive the first message within the first preset time and determines that the vehicle networking terminal is removed, the meter starts the internal countdown; or when the meter receives the first message that the vehicle signal status is no signal, the meter starts the internal countdown.

[0081] When the meter does not receive the first message sent by the vehicle networking terminal within the first preset time, it is necessary to continue to determine whether the vehicle networking terminal is removed. When it is determined that the vehicle networking terminal is removed, the meter will start the internal countdown. In addition, when the vehicle signal status in the first message sent by the vehicle networking terminal received by the meter is no signal, the meter will also start the internal countdown.

[0082] In some embodiments of the present application, when the vehicle signal state is signaled, the method for setting the initial value of the instrument countdown may include: the vehicle networking terminal receives and parses the instruction for setting the pre-embedded lock duration issued by the vehicle networking platform, the vehicle networking terminal sends the instruction information for setting the pre-embedded lock duration to the instrument, after the instrument receives the instruction information for setting the pre-embedded lock duration, the instrument sends the second random seed to the vehicle networking terminal, and at the same time, the instrument calculates the third key based on the second random seed, after the vehicle networking terminal receives the second random seed, it calculates the fourth key based on the second random seed, and feeds the fourth key back to the instrument. After the instrument receives the fourth key, it determines whether the third key is consistent with the fourth key, and when the third key is consistent with the fourth key, the pre-embedded lock duration is set according to the instruction information for setting the pre-embedded lock duration, and the pre-embedded lock duration is the initial value of the instrument countdown.

[0083] The Internet of Vehicles platform refers to the use of new generation information and communication technologies to achieve network connections between vehicles, vehicles and infrastructure, vehicles and pedestrians, and vehicles and services, so as to improve the overall intelligent driving level of vehicles and provide users with safe, comfortable, intelligent, and efficient driving experience and transportation services. These platforms provide different functional services for vehicle operation by effectively utilizing all vehicle dynamic information in the information network platform, such as ensuring the distance between vehicles, reducing the probability of collision accidents, providing real-time navigation, and improving the efficiency of traffic operation through communication with other vehicles and network systems.

[0084] When the Internet of Vehicles platform exchanges information with the vehicle's software or hardware devices, a 4G network is required. When the network is poor or the vehicle's signal status is no signal, the Internet of Vehicles platform cannot exchange information with the vehicle's software or hardware devices.

[0085] In some embodiments of the present application, Figure 3 As shown, in S300, the instrument or the vehicle networking terminal performs vehicle locking management according to the vehicle signal state and the reception of the first message and the second message. Specific steps may also include:

[0086] S321: When the vehicle has no signal for more than a second preset time, determining whether the vehicle networking terminal can receive the second message;

[0087] When the vehicle networking terminal is operating normally, the vehicle networking terminal has not been disassembled and its components are not damaged. The vehicle networking terminal first determines its own networking status through the internal networking module. If the networking status is good, the vehicle operates normally and the vehicle networking terminal does not perform any processing.

[0088] When the vehicle signal status shows that there is no signal through the signal status of the on-board networking terminal, the time when the vehicle signal status is no signal is monitored. When the vehicle has no signal for more than a second preset time, the second preset time can also be pre-set. For example, the second preset time is set to 1 hour. It is necessary to determine whether the on-board networking terminal can receive the second message sent by the instrument. Based on whether the second message can be received, it can be determined whether the instrument is dismantled.

[0089] S322: When the in-vehicle networking terminal cannot receive the second message, the vehicle locking function of the in-vehicle networking terminal is activated.

[0090] If the vehicle-mounted networking terminal cannot receive the message sent by the instrument, the possible situations are that the instrument is disassembled, the instrument is damaged, or the wiring harness connecting the instrument and the vehicle-mounted networking terminal is faulty. When the vehicle-mounted networking terminal cannot receive the second message sent by the instrument, no matter which of the above situations is the case, the vehicle locking function of the vehicle-mounted networking terminal will be activated, and the vehicle-mounted networking terminal will trigger the controller to lock the vehicle.

[0091] In some embodiments of the present application, when the in-vehicle networking terminal cannot receive the second message in S322, the specific steps of activating the vehicle locking function of the in-vehicle networking terminal may include:

[0092] When the vehicle networking terminal cannot receive the second message and determines that the instrument is disassembled, the vehicle locking function of the vehicle networking terminal is activated. When the vehicle networking terminal cannot receive the second message sent by the instrument, it is necessary to first determine whether the instrument is disassembled. When it is determined that the instrument is disassembled, the vehicle locking function of the vehicle networking terminal can be activated.

[0093] In some embodiments of the present application, Figure 4 As shown, the vehicle unlocking method of the present application also includes:

[0094] After the vehicle is powered on, the controller determines the activation state of the vehicle locking function. If the activation state of the vehicle locking function is activated, the controller generates a first random seed and calculates a first key based on the first random seed.

[0095] The controller sends the first random seed to the in-vehicle networking terminal. After receiving the first random seed, the in-vehicle networking terminal calculates the second key according to the first random seed and feeds the second key back to the controller.

[0096] After receiving the second key, the controller determines whether the first key is consistent with the second key. When the first key is inconsistent with the second key, the handshake verification fails and the controller locks the vehicle; when the first key is consistent with the second key, the vehicle drives normally.

[0097] Every time the vehicle is powered on, the controller triggers a handshake check to determine whether the vehicle networking terminal has been dismantled. When the handshake check fails, it can be determined that the vehicle networking terminal has been dismantled, and then the controller locks the vehicle, realizing an anti-dismantling solution for the vehicle networking terminal, which is more secure.

[0098] When the handshake verification fails, the possible situations are that the vehicle networking terminal has been disassembled, the components of the vehicle networking terminal are damaged, the wiring harness connecting the controller and the vehicle networking terminal is faulty, or the vehicle networking terminal has not been calibrated after being replaced.

[0099] In some embodiments of the present application, if the handshake verification fails, the controller locks the vehicle, and the specific steps may also include:

[0100] When the handshake verification fails, it is determined whether the vehicle-mounted networking terminal is dismantled. When it is determined that the vehicle-mounted networking terminal is dismantled, the controller locks the vehicle.

[0101] In some embodiments of the present application, Figure 5 As shown, the vehicle unlocking method of the present application also includes:

[0102] When the vehicle signal state is signaled and the vehicle locking function activation state is activated, the vehicle networking platform sends a vehicle locking command to the vehicle networking terminal, the vehicle networking terminal sends a vehicle locking command to the controller, and the controller locks the vehicle.

[0103] In some embodiments of the present application, Figure 6 As shown, the vehicle unlocking method of the present application also includes:

[0104] When the vehicle is in a locked state and has a signal, the vehicle networking platform sends an unlocking command to the vehicle networking terminal, and the vehicle networking terminal sends an unlocking command to the controller, and the controller unlocks.

[0105] In some implementations, when it is determined that the vehicle is locked due to the removal of the vehicle-mounted networking terminal or the instrument, the vehicle can be unlocked after the vehicle-mounted networking terminal or the instrument is reconnected.

[0106] In some embodiments, when the vehicle is in a no-signal state, a staff member with operating authority can go to the site and unlock the vehicle by entering a password at the meter end.

[0107] In some embodiments of the present application, Figure 7 As shown, the vehicle unlocking method of the present application also includes:

[0108] When the vehicle-mounted networking terminal triggers vehicle locking due to a component failure, the instrument responds to the key corresponding to the vehicle-mounted networking terminal of the vehicle input by the user, and sends an unlock message and a preset unlock time to the controller. The controller unlocks the vehicle according to the unlock message within the preset unlock time.

[0109] By observing the indicator lights of the vehicle networking terminal and judging the status of each module of the vehicle networking terminal, it is possible to confirm whether the components of the vehicle networking terminal are abnormal. In addition, when the components of the vehicle networking terminal are damaged, the vehicle will be locked if the handshake verification fails when it is powered on. When it is confirmed that the vehicle networking terminal is locked due to a component failure, if the customer needs to move the vehicle urgently, the emergency unlocking function can be turned on. Specifically, personnel with operating authority need to operate locally in the vehicle and enter the key of the vehicle networking terminal of this vehicle in the instrument interface. After the instrument responds to the key corresponding to the vehicle networking terminal of the vehicle entered by the user, it sends the unlocking message and the preset unlocking time to the controller. The controller unlocks according to the unlocking message within the preset unlocking time.

[0110] The preset unlocking time refers to the length of time that the vehicle can be temporarily unlocked. For example, the preset unlocking time can be set to 3 hours. After the vehicle runs for the preset unlocking time, if the components of the vehicle networking terminal are still abnormal, the handshake verification will continue to be triggered. If the handshake verification fails, the vehicle will be locked.

[0111] In addition to the vehicle networking platform sending an unlocking command to the vehicle networking terminal when the vehicle has a signal, the vehicle networking terminal sending an unlocking command to the controller, and the controller unlocking or locking the vehicle, this application also adds a judgment on the removal of the instrument and the vehicle networking terminal, and different unlocking schemes for the vehicle when the instrument and the vehicle networking terminal are removed. By increasing the choice of unlocking methods, the dependence of unlocking the vehicle on signals can be reduced, and the vehicle can be unlocked when there is no signal and the instrument and the vehicle networking terminal are removed.

[0112] Exemplary Systems

[0113] In some embodiments of the present application, Figure 8 As shown, a vehicle unlocking system is provided, comprising:

[0114] The vehicle networking terminal is used to periodically send a first message to the instrument, where the first message includes a vehicle signal status and a vehicle locking function activation status;

[0115] The instrument is used to periodically send a second message to the vehicle-mounted networking terminal, where the second message includes the pre-embedded locking state and the remaining pre-embedded locking time, and to manage the vehicle locking according to the signal state of the vehicle-mounted networking terminal and the reception of the first message and the second message.

[0116] In some embodiments of the present application, Fig. 9 As shown, the vehicle unlocking system of the present application also includes:

[0117] The controller is used to determine the activation state of the vehicle locking function. If the activation state of the vehicle locking function is activated, a first random seed is generated, a first key is calculated based on the first random seed, and the first random seed is sent to the vehicle networking terminal. After receiving the first random seed, the vehicle networking terminal calculates a second key based on the first random seed, and feeds the second key back to the controller. After receiving the second key, the controller determines whether the first key is consistent with the second key. When the first key is inconsistent with the second key, the handshake verification fails, and the controller locks the vehicle; when the first key is consistent with the second key, the handshake verification passes, and the vehicle drives normally.
