Description

Technical Field

[0001] The present application relates to the field of vehicle control technology, and more specifically, to a vehicle starting method, a vehicle, a vehicle key and a computer-readable storage medium in the field of vehicle control technology. Background Art

[0002] When the vehicle key receives the low frequency (LF) data sent by the vehicle's power start system (PS), it will send radio frequency (RF) data to the power start system. If the battery of the vehicle key is too low, if the vehicle key sends radio frequency data to the power start system under low battery conditions, the voltage of the vehicle key will be instantly pulled down, causing the key chip of the vehicle key to be constantly reset. Since the key chip is reset, the vehicle key cannot work normally during the reset period, resulting in failure to start the vehicle through the vehicle key. Summary of the invention

[0003] The present application provides a vehicle starting method, a vehicle, a vehicle key and a computer-readable storage medium. The present application can ensure the normal starting of the vehicle when the battery power of the vehicle key is too low and the vehicle key cannot work due to sending radio frequency data to the vehicle, thereby improving the reliability of the vehicle key.

[0004] In a first aspect, a vehicle starting method is provided, the vehicle starting method comprising: when the vehicle starting conditions are met, determining whether a vehicle key is reset; if so, detecting whether the vehicle key is placed in a backup starting device of the vehicle; wherein, when the vehicle key is placed in the backup starting device, the backup starting device supplies power to the vehicle key; if so, entering a security verification mode, and authenticating the vehicle key through the vehicle; and starting the vehicle when the identity authentication of the vehicle key is passed.

[0005] In the above technical scheme, the vehicle starting method adopted in the embodiment of the present application, when the vehicle starting conditions are met, if it is determined that the vehicle key is reset, then it is detected whether the vehicle key is placed in the vehicle's backup starting device. If it is detected that the vehicle key is placed in the backup starting device, the backup starting device supplies power to the vehicle key, indicating that the vehicle key has sufficient power to interact with the vehicle for data at this time. The vehicle key then enters a security verification mode, and the vehicle authenticates the vehicle key through the vehicle to verify the legitimacy of the vehicle key. If the verification passes, the vehicle is started, which can ensure that the vehicle starts normally. This solves the problem that when the battery power of the vehicle key is too low, the vehicle key sends radio frequency data to the vehicle to lower the voltage of the vehicle key, causing the vehicle key to send a reset and fail to work, which is beneficial to improving the reliability of the vehicle key.

[0006] In combination with the first aspect, in some possible implementations, determining whether the vehicle key has been reset includes: obtaining a reset identifier stored in the vehicle key; if the reset identifier is a first identifier, determining that the vehicle key has not been reset; if the reset identifier is a second identifier, determining that the vehicle key has been reset.

[0007] In the above technical solution, judging whether the vehicle key has been reset is performed by using the reset mark stored in the vehicle key, which can quickly judge whether the vehicle key has been reset and is beneficial to improving the accuracy of the judgment.

[0008] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the vehicle starting method also includes a scheme for storing the reset flag: if the first setting condition is met, the reset flag is set to the second flag, and the second flag is stored; wherein, the first setting condition includes that the remaining power of the vehicle key is less than the power threshold, and the vehicle key sends a security verification feedback to the vehicle; if the second setting condition is met, the reset flag is set to the first flag, and the first flag is stored; wherein, the second setting condition includes that the remaining power is greater than or equal to the power threshold, the identity authentication of the vehicle key is passed, when the identity authentication of the vehicle key is passed, the door lock button of the vehicle key is triggered, and the vehicle key receives at least one of the door lock authentication request sent by the vehicle.

[0009] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the vehicle starting method also includes: when the vehicle key is placed in the backup starting device, sending an owner identity authentication instruction to the vehicle; wherein, when the vehicle receives the key anti-theft verification instruction, it outputs a first reminder message, and the first reminder message is used to remind the user to enter the vehicle starting token reserved by the owner, and when it is determined that the vehicle starting token entered by the user is consistent with the reserved vehicle starting token, sending an owner identity authentication pass instruction to the vehicle key; when the owner identity authentication pass instruction is received, executing the step of entering the security verification mode and authenticating the vehicle key through the vehicle.

[0011] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the vehicle starting method also includes: when the vehicle starting conditions are met, determining whether the remaining power of the vehicle key is less than or equal to a power threshold; if so, executing the step of determining whether the vehicle key is reset.

[0012] In the above technical solution, on the one hand, when the vehicle key has sufficient power to support the vehicle key to start the vehicle according to the normal vehicle starting process, it is not necessary to determine whether the vehicle key is reset, which is conducive to shortening the vehicle starting time. On the other hand, when the vehicle key power does not support the vehicle key to start the vehicle according to the normal vehicle starting process, it is determined whether the vehicle key is reset, which can ensure the normal start of the vehicle.

[0013] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, after determining whether the vehicle key has been reset, the vehicle starting method also includes: when the vehicle key has been reset, controlling the vehicle key to output a second reminder message to remind the user to place the vehicle key in the backup starting device, and executing the step of detecting whether the vehicle key is placed in the backup starting device of the vehicle.

[0014] In the above technical solution, when the vehicle key has been reset, the user can be reminded how to start the vehicle by another method of using the vehicle key, which is conducive to improving the user's vehicle use experience.

[0015] In combination with the first aspect and the above implementation, in some possible implementations, the vehicle key is controlled to perform information interaction with the vehicle to authenticate the vehicle key. By authenticating the vehicle key through information interaction, it can be ensured that only the vehicle key that has passed the authentication can start the vehicle, thereby improving the safety of the vehicle.

[0033] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0034] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0035] The vehicle key of the vehicle will send radio frequency data to the one-button start system when the vehicle key receives the low-frequency data sent by the vehicle's one-button start system. If the battery of the vehicle key is too low, if the vehicle key sends radio frequency data to the one-button start system under low battery conditions, the voltage of the vehicle key will be instantly pulled down, causing the key chip of the vehicle key to be constantly reset. Since the key chip has been reset, the vehicle key cannot work normally during the reset period, resulting in failure to start the vehicle through the vehicle key.

[0036] Based on the above problems, the present application provides a vehicle starting method, a vehicle, a vehicle key and a computer-readable storage medium. When the battery power of the vehicle key is too low and the vehicle key cannot work due to sending radio frequency data to the vehicle due to resetting, the present application can stop sending radio frequency data to the vehicle and instead start the vehicle through anti-theft verification when the vehicle key is placed on a device on the vehicle that temporarily powers the vehicle key, thereby ensuring that the vehicle starts normally, which is beneficial to improving the reliability of the vehicle key.

[0037] The following is an embodiment of a vehicle starting method provided in an embodiment of the present application.

[0038] Figure 1 A schematic flow chart of a vehicle starting method provided by an embodiment of the present application is shown, such as Figure 1 As shown, the vehicle starting method provided in the embodiment of the present application is implemented by the vehicle key and the vehicle. The above vehicle starting method includes the following schemes:

[0039] S110: When the vehicle startup conditions are met, determining whether the vehicle key is reset;

[0040] S120: When the vehicle key is reset, detecting whether the vehicle key is placed in a backup starting device of the vehicle;

[0041] S130: When the vehicle key is placed in the backup starting device, enter the security verification mode and authenticate the vehicle key through the vehicle;

[0042] S140: When the identity authentication of the vehicle key is passed, start the vehicle.

[0043] In an exemplary embodiment, the vehicle key determines whether it meets the vehicle's startup conditions, and the vehicle's startup conditions include: the distance between the vehicle key and the vehicle is less than or equal to a preset distance, and / or the vehicle key is inserted into the ignition lock. When the vehicle key determines that it meets the vehicle's startup conditions, it determines whether it has been reset. The reason for the vehicle key to be reset is that if the battery power of the vehicle key is too low, when the vehicle key sends radio frequency data to the vehicle, the voltage of the vehicle key will be instantly pulled down, causing the vehicle key to send a reset. After the vehicle key is reset, the vehicle key cannot work and can no longer send radio frequency data to the vehicle, resulting in a failure to start the vehicle. Among them, whether the vehicle key is reset refers to whether the key chip of the vehicle key is reset.

[0044] The normal vehicle startup process is: if the vehicle key has not been reset, that is, the vehicle key can send radio frequency data to the vehicle, the vehicle's anti-theft system authenticates the vehicle key based on the radio frequency data sent by the vehicle key to verify the legitimacy of the vehicle key. If the verification passes, the vehicle is started and the security verification mode is exited.

[0045] If the vehicle key determines that it has been reset, indicating that the vehicle cannot be started through the normal vehicle startup process, it will enter the security verification mode (which can be understood as the anti-theft mode) and wait. During the waiting process, it will detect whether the vehicle key is placed in the vehicle's backup starting device and the vehicle key will no longer send radio frequency data to the vehicle. Figure 2 As shown, Figure 2 A schematic diagram of a vehicle key and a backup starting device is shown, 100 represents the backup starting device, 200 represents the vehicle key, and the backup starting device can be set in the vehicle cabin, for example, at the main driving console, or can be set outside the vehicle cabin, for example, at the left front door. When the vehicle key is placed in the backup starting device, the backup starting device supplies power to the vehicle key. The power supply principle is as follows: the vehicle key includes a coil, and the backup starting device includes a coil. When the vehicle key contacts or approaches the backup starting device, the coil in the vehicle key couples with the coil in the backup starting device, and the backup starting device supplies power to the vehicle key.

[0046] The vehicle key detects that it is placed in the vehicle's backup starting device, and the backup starting device supplies power to the vehicle key. During the period when the backup starting device supplies power to the vehicle key, the vehicle key enters a security verification mode, and the vehicle key is authenticated by the vehicle's anti-theft system to verify the legitimacy of the vehicle key. If the verification passes, the vehicle is started.

[0047] The vehicle starting method adopted in the embodiment of the present application, when the vehicle starting conditions are met, if it is determined that the vehicle key is reset, then detects whether the vehicle key is placed in the vehicle's backup starting device. If it is detected that the vehicle key is placed in the backup starting device, the backup starting device supplies power to the vehicle key, indicating that the vehicle key now has sufficient power to interact with the vehicle for data. The vehicle key then enters a security verification mode, and authenticates the vehicle key through the vehicle to verify the legitimacy of the vehicle key. If the verification passes, the vehicle is started, which can ensure that the vehicle starts normally. This solves the problem that when the battery power of the vehicle key is too low, the vehicle key sends radio frequency data to the vehicle to lower the voltage of the vehicle key, causing the vehicle key to send a reset and fail to work. This is beneficial to improving the reliability of the vehicle key.

[0048] The following Figure 1 The specific implementation methods of each step in the embodiment shown are described as follows:

[0049] In a possible implementation, the above-mentioned determination of whether the vehicle key is reset includes the following schemes:

[0050] Get the reset flag stored in the vehicle key;

[0051] If the reset mark is the first mark, it is determined that the vehicle key has not been reset;

[0052] If the reset mark is the second mark, it is determined that the vehicle key is reset.

[0053] The storage unit (Electrically Erasable Programmable Read-Only Memory, EEPROM) of the vehicle key stores a reset flag for indicating whether the vehicle key has been reset. The reset flag includes a first flag and a second flag. If the reset flag is the first flag (for example, the first flag is "0"), it indicates that the vehicle key has not been reset; if the reset flag is the second flag (for example, the second flag is "1"), it indicates that the vehicle key has been reset. By judging whether the vehicle key has been reset by the reset flag stored in the vehicle key, it is possible to quickly judge whether the vehicle key has been reset, and it is helpful to improve the accuracy of the judgment.

[0054] In a possible implementation, the vehicle starting method further includes a solution for storing a reset flag:

[0055] If a first setting condition is met, the reset flag is set to the second flag and the second flag is stored, the first setting condition including that the remaining power of the vehicle key is less than the power threshold and the vehicle key sends a safety verification feedback to the vehicle;

[0056] If the second setting condition is met, the reset flag is set to the first flag and the first flag is stored. The second setting condition includes at least one of the remaining power being greater than or equal to the power threshold, the vehicle key identity authentication being passed, the vehicle key door lock button being triggered when the vehicle key identity authentication is passed, and the vehicle key receiving a door lock authentication request sent by the vehicle.

[0057] The process of storing the reset flag of the vehicle key is as follows: if it is determined that the remaining power of the vehicle key is less than the power threshold, the vehicle key receives a security verification request from the vehicle (the above-mentioned low-frequency data), and sends security verification feedback to the vehicle (the above-mentioned radio frequency data), then the reset flag is set to the second flag, and then the second flag is stored.

[0058] If it is determined that the remaining power of the vehicle key is greater than or equal to the power threshold, it means that the vehicle key has sufficient power to support the vehicle key to respond to the vehicle's security verification request and send security verification feedback to the vehicle, so the reset flag is set to the first flag, and then the first flag is stored. If it is determined that the identity authentication of the vehicle key is passed, that is, there is no need to send security verification feedback to the vehicle this time, so the reset flag is set to the first flag, and then the first flag is stored. If it is determined that the identity authentication of the vehicle key is passed, and the door lock button of the vehicle key is triggered, or it is determined that the identity authentication of the vehicle key is passed, and the vehicle key receives the door lock authentication request sent by the vehicle, it means that the user has finished using the vehicle and has locked the vehicle, then the reset flag is set to the first flag, and then the first flag is stored. If the user needs to start the vehicle again, re-execute the above S110-S140.

[0059] In a possible implementation, the vehicle starting method further includes the following solution:

[0060] When the vehicle key is placed in the standby starting device, a vehicle owner identity authentication instruction is sent to the vehicle; wherein, when the vehicle receives the key anti-theft authentication instruction, the vehicle outputs a first reminder message, the first reminder message is used to remind the user to input the vehicle start token reserved by the vehicle owner, and when it is determined that the vehicle start token input by the user is consistent with the reserved vehicle start token, the vehicle owner identity authentication pass instruction is sent to the vehicle key;

[0061] When the vehicle owner's identity authentication is passed, a step of entering a security authentication mode and authenticating the vehicle key through the vehicle is executed.

[0062] Considering the situation that the vehicle key is reset after being lost or stolen, in order to prevent the vehicle from being started by a user who is not the owner, when the vehicle key is placed in the backup starting device, the vehicle key sends the owner identity authentication instruction to the vehicle to instruct the vehicle to verify whether the user using the vehicle key is the owner. After receiving the key anti-theft verification instruction, the vehicle enters the owner identity authentication mode, that is, outputs the first reminder information, which is used to remind the user to enter the vehicle startup token reserved by the owner. The vehicle startup token includes one or more combinations of sound, action, expression, etc. After the user enters the vehicle startup token, it is determined whether the vehicle startup token entered by the user is consistent with the vehicle startup token reserved by the owner in the vehicle. If they are inconsistent, it means that the user using the vehicle key is not the owner, and the vehicle is not started to prevent the vehicle from being stolen; if they are consistent, it means that the user using the vehicle key is the owner, and the security verification mode is executed to perform the steps of authenticating the vehicle key through the vehicle, thereby ensuring the safety of the vehicle.

[0063] In a possible implementation, before determining whether the vehicle key is reset, the vehicle starting method further includes the following solutions:

[0064] When the vehicle start-up conditions are met, determining whether the remaining power of the vehicle key is less than or equal to a power threshold;

[0065] If so, the step of determining whether the vehicle key has been reset is performed.

[0066] When the vehicle key determines that it meets the vehicle startup conditions, it further determines whether its remaining power is less than or equal to the power threshold. If the remaining power is greater than the power threshold, it means that the power is sufficient, and the vehicle key has sufficient power to support the vehicle key to respond to the vehicle's security verification request and send security verification feedback to the vehicle, that is, the vehicle key will not be reset due to sending security verification feedback to the vehicle. Therefore, the vehicle is started according to the normal vehicle startup process to avoid having to determine whether the vehicle key is reset every time, which is conducive to shortening the vehicle startup time. If the remaining power is less than or equal to the power threshold, it means that the vehicle key's power cannot support the vehicle key to respond to the vehicle's security verification request and send security verification feedback to the vehicle, and then execute the steps of determining whether the vehicle key is reset to starting the vehicle when the vehicle key's identity verification passes, thereby ensuring that the vehicle starts normally.

[0067] In a possible implementation, after determining whether the vehicle key is reset, the vehicle starting method further includes the following solutions:

[0068] When the vehicle key is reset, the vehicle key is controlled to output a second reminder message to remind the user to place the vehicle key in the backup starting device, and a step of detecting whether the vehicle key is placed in the backup starting device of the vehicle is performed.

[0069] When designing a vehicle, the vehicle starting method provided by the embodiment of the present application has been implanted in the vehicle key and the vehicle, and the vehicle's instructions for use will record how to start the vehicle through the second starting process (i.e., the vehicle starting method provided by the embodiment of the present application) when the vehicle cannot be started according to the normal vehicle starting process (the vehicle cannot be started when the vehicle key is too low). Considering that some users may forget or have not learned about the second starting process through the instructions, when it is determined that the vehicle key is reset, the vehicle key is allowed to output a second reminder message, thereby reminding the user to place the vehicle key in the standby starting device, and then performing the step of detecting whether the vehicle key is placed in the standby starting device of the vehicle. Among them, the second reminder message can be to light up the indicator light or / and make a sound between the vehicle keys. It is also considered that since the vehicle key has been reset, the vehicle key cannot work, but the reset indicator light of the vehicle key can be designed. When the reset indicator light is on, if the user who has read the vehicle manual can understand that the vehicle needs to be started using the second starting process, the vehicle key will be placed in the standby starting device. When the reset indicator light is on, for users who have not read the vehicle manual, if the vehicle detects that the reset indicator light is on, a sound message will be played through the vehicle to remind the user to place the vehicle key in the backup starting device.

[0070] In a possible implementation, after determining whether the vehicle key is reset, authenticating the vehicle key through the vehicle includes the following solutions:

[0071] Control the vehicle key to exchange information with the vehicle to authenticate the vehicle key.

[0072] During the period when the backup starting device supplies power to the vehicle key, the vehicle key enters a security verification mode, the vehicle key obtains a first encryption algorithm, a random number, and a key identifier of the vehicle key, encrypts the random number and the key identifier by the first encryption algorithm to obtain a first ciphertext, generates first verification information by the first ciphertext and the key identifier, and sends the first verification information to the anti-theft system of the vehicle, the anti-theft system parses the first verification information to obtain the ciphertext and the key identifier, the anti-theft system obtains a stored second encryption algorithm corresponding to the key identifier, decrypts the ciphertext by the second encryption algorithm to obtain the random number and the key identifier. The anti-theft system encrypts the random number and the key identifier by the second encryption algorithm to obtain a second ciphertext, generates first feedback information by the second ciphertext, sends the first feedback information to the vehicle key, the vehicle key decrypts the first feedback information by the first encryption algorithm to obtain a random number and the key identifier, encrypts the random number and the key identifier by the first encryption algorithm to obtain a third ciphertext, generates second verification information by the third ciphertext, and sends the second verification information to the anti-theft system of the vehicle. The anti-theft system decrypts the second feedback information through a second encryption algorithm to obtain a random number and a key identification, and if it confirms that the identity authentication of the vehicle key has passed, it allows the vehicle to start, and sends a third feedback information indicating that the identity authentication of the vehicle key has passed to the vehicle key. After receiving the third feedback information, the vehicle key stops interacting with the anti-theft system, the security verification ends, and the security verification mode is exited.

[0073] Figure 3 Another schematic flow chart of a vehicle starting method provided by an embodiment of the present application is shown. Figure 3 As shown, the vehicle starting method provided in the embodiment of the present application is implemented by the vehicle key and the vehicle. The above vehicle starting method includes the following schemes:

[0074] S210: When the vehicle key meets the vehicle startup conditions, determine whether the vehicle key is reset. The startup conditions include: the distance between the vehicle key and the vehicle is less than or equal to the preset distance, and / or the vehicle key is inserted into the ignition lock. The vehicle key obtains the reset identifier stored in the vehicle key; if the reset identifier is the first identifier, it is determined that the vehicle key has not been reset; if the reset identifier is the second identifier, it is determined that the vehicle key has been reset.

[0075] S211: When the vehicle key is reset, the vehicle key is detected to see if it is placed in the vehicle's backup starting device. If the vehicle key is not reset, that is, the vehicle key is able to send radio frequency data to the vehicle, the vehicle's anti-theft system authenticates the vehicle key based on the radio frequency data sent by the vehicle key to verify the legitimacy of the vehicle key. If the verification is successful, the vehicle is started and the safety verification mode is exited. If the vehicle key determines that the vehicle key is reset, indicating that the vehicle key cannot start the vehicle through the normal vehicle starting process, the vehicle enters the safety verification mode and waits. During the waiting process, the vehicle key is detected to see if it is placed in the vehicle's backup starting device, and the vehicle key no longer sends radio frequency data to the vehicle.

[0076] S212: The vehicle key enters the safety verification mode when the vehicle key is placed in the backup starting device. The vehicle key detects that the vehicle key is placed in the backup starting device of the vehicle, and the backup starting device supplies power to the vehicle key. During the period when the backup starting device supplies power to the vehicle key, the vehicle key enters the safety verification mode, and the vehicle key can work normally and can interact with the vehicle.

[0077] S213: The vehicle key generates first verification information. While the backup starting device is powering the vehicle key, the vehicle key enters a security verification mode, and the vehicle key obtains a first encryption algorithm, a random number, and a key identifier of the vehicle key, encrypts the random number and the key identifier by the first encryption algorithm, obtains a first ciphertext, and generates first verification information by the first ciphertext and the key identifier.

[0078] S214: The vehicle key sends the first verification information to the vehicle, that is, the vehicle key sends the first verification information to the anti-theft system of the vehicle.

[0079] S215: The vehicle decrypts the first verification information and generates first feedback information, that is, the vehicle's anti-theft system parses the first verification information to obtain a ciphertext and a key identifier, the anti-theft system obtains a stored second encryption algorithm corresponding to the key identifier, decrypts the ciphertext through the second encryption algorithm to obtain a random number and the key identifier, and the anti-theft system encrypts the random number and the key identifier through the second encryption algorithm to obtain a second ciphertext, and generates the first feedback information through the second ciphertext.

[0080] S216: The vehicle sends first feedback information to the vehicle key, that is, the anti-theft system of the vehicle sends the first feedback information to the vehicle key.

[0081] S217: The vehicle key decrypts the first feedback information and generates second verification information, that is, the vehicle key decrypts the first feedback information through the first encryption algorithm to obtain a random number and a key identifier, and then encrypts the random number and the key identifier through the first encryption algorithm to obtain a third ciphertext, and generates the second verification information through the third ciphertext.

[0082] S218: The vehicle key sends the second verification information to the vehicle, that is, the vehicle key sends the second verification information to the anti-theft system of the vehicle.

[0083] S219: The vehicle decrypts the second verification information, confirms that the identity authentication of the vehicle key has passed, and starts the vehicle. That is, the vehicle's anti-theft system decrypts the second feedback information through the second encryption algorithm, obtains a random number and a key identifier, confirms that the identity authentication of the vehicle key has passed, and then allows the vehicle to start.

[0084] S220: The vehicle sends third feedback information to the vehicle key. The anti-theft system of the vehicle sends the third feedback information to the vehicle key. The third feedback information is used to indicate that the identity authentication of the vehicle key has passed.

[0085] S221: The vehicle key exits the safety verification mode, that is, after receiving the third feedback information, the vehicle key stops exchanging information with the anti-theft system, the safety verification ends, the safety verification mode is exited, and the vehicle is started.

[0086] Based on the vehicle starting method provided in the embodiment of the present application, when the vehicle starting conditions are met, if it is determined that the vehicle key is reset, it is then detected whether the vehicle key is placed in the vehicle's backup starting device. If it is detected that the vehicle key is placed in the backup starting device, the backup starting device powers the vehicle key, indicating that the vehicle key has sufficient power to interact with the vehicle for data. The vehicle key then enters a security verification mode, and the vehicle authenticates the vehicle key through the vehicle to verify the legitimacy of the vehicle key. If the verification passes, the vehicle is started, which can ensure that the vehicle starts normally. This solves the problem that when the battery power of the vehicle key is too low, the vehicle key sends radio frequency data to the vehicle to lower the voltage of the vehicle key, causing the vehicle key to send a reset and fail to work. This is beneficial to improving the reliability of the vehicle key.
