Abstract
Description
Technical Field
[0001] The present application relates to the field of vehicle technology, and in particular to a vehicle authorization start method and system. Background Art
[0002] With the development of intelligent vehicles, the vehicle startup methods are becoming more and more diverse and intelligent, basically including the following startup methods: mechanical key startup, RF / Bluetooth remote control key startup, placeholder startup, face recognition startup, NFC card startup, APP startup, etc. Regardless of the above startup method, the validity of the key (including key, personnel identity, card, mobile phone) information needs to be authenticated, and these authentications require corresponding software and hardware as support. When performing identity validity authentication, the resources required by the key and the vehicle end are as follows: Figure 1 As shown in Table 1. For some vehicles, spare pure mechanical keys (only key teeth) cannot be authenticated due to the lack of coils and corresponding information processing chips, that is, the vehicle cannot be started. Summary of the invention
[0003] In view of the above problems, the present application provides a vehicle authorization start method and system to solve the problem that some existing vehicles have pure mechanical keys with only key teeth and cannot start the vehicle because they do not have a coil and a corresponding information processing chip and cannot perform identity authentication.
[0004] To achieve the above object, the inventor provides a vehicle authorization start method, comprising the following steps:
[0005] When the body controller detects that the door is opened by a mechanical key and there is no identity validity information, it sends an alarm message to the smart cockpit;
[0006] After receiving the alarm information, the smart cockpit sends a verification request to the operator;
[0007] The verification information input by the operator is obtained, and the smart cockpit confirms the received verification information;
[0008] When the confirmation is passed, the power mode of the body controller is switched to the power-on mode;
[0009] After receiving the start operation from the operator, the body controller switches the power mode to the ignition mode.
[0010] In some embodiments, the verification information is a startup password or voiceprint information or fingerprint information.
[0011] In some embodiments, the following steps are also included:
[0012] The startup password set by the user is obtained through the diagnostic instrument and sent to the vehicle's smart cockpit or body controller.
[0013] In some embodiments, the smart cockpit confirms the received verification information specifically including the following steps:
[0014] The smart cockpit sends authentication request information to the body controller;
[0015] After receiving the serious request information, the body controller provides a random number to the smart cockpit;
[0016] The smart cockpit encrypts the verification information according to the random number provided by the body controller to obtain the authentication ciphertext and sends it to the body controller;
[0017] The body controller decrypts and verifies the received authentication ciphertext.
[0018] In some embodiments, when the vehicle body controller detects that the vehicle door is opened by a mechanical key and there is no identity validity information, sending an alarm message to the smart cockpit specifically includes the following steps:
[0019] When the body controller detects that the door is opened by a mechanical key and there is no identity validity information, the anti-theft alarm is triggered and an alarm message is sent to the smart cockpit.
[0020] Another technical solution is provided, a vehicle authorization start system, comprising:
[0021] The body controller is used to send an alarm message to the smart cockpit when it detects that the door is opened by a mechanical key and there is no identity validity information. When the verification information is confirmed to be passed, the power mode is switched to the power-on mode. After receiving the start operation of the operator, the body controller switches the power mode to the ignition mode;
[0022] The smart cockpit is used to send a verification request to the operator after receiving an alarm message, and after obtaining the verification information input by the operator, confirm the received verification information.
[0023] In some embodiments, the verification information is a startup password or voiceprint information or fingerprint information.
[0024] In some embodiments, it also includes:
[0025] The diagnostic instrument is used to obtain the startup password set by the user and send it to the vehicle's smart cockpit or body controller.
[0026] In some embodiments, the smart cockpit is further used to send authentication request information to the body controller. After receiving the random number sent by the body controller, the verification information is encrypted according to the random number provided by the body controller to obtain the authentication ciphertext, and sent to the body controller;
[0027] The body controller is also used to provide a random number to the smart cockpit after receiving the authentication request information sent by the smart cockpit, and to decrypt and verify after receiving the authentication ciphertext sent by the smart cockpit.
[0028] In some embodiments, the body controller is also used to trigger an anti-theft alarm and send an alarm message to the smart cockpit when it detects that the vehicle door is opened by a mechanical key and there is no identity validity information.
[0029] Different from the prior art, the above technical solution is that when the user opens the vehicle with a pure mechanical key with only a key tooth, the body controller detects that the door is opened by the mechanical key, and then when valid identity information is obtained, the body controller sends an alarm message to the smart cockpit. After the smart cockpit receives the alarm message, it sends a verification request to the operator to obtain the verification information entered by the operator. After obtaining the verification information entered by the operator, the verification information is confirmed. After the confirmation is passed, the power mode of the body controller is switched to the power-on mode, and then the start operation of the operator is received. After receiving the start operation of the operator, the body controller switches the power mode to the ignition mode. This realizes the verification of the operator's identity when the vehicle is opened with a mechanical key with only a key tooth, and then starts the vehicle.

[0055] TBox: A remote communication module with 4G communication capabilities that can send in-car data to a service platform.
[0056] See also Figure 2 This embodiment provides a vehicle authorization start method, including the following steps:
[0057] Step S210: When the body controller detects that the door is opened by the mechanical key and there is no identity validity information, an alarm message is sent to the smart cockpit;
[0058] Step S220: After receiving the alarm information, the smart cockpit sends a verification request to the operator;
[0059] Step S230: obtaining the verification information input by the operator, and the smart cockpit confirming the received verification information;
[0060] Step S240: When the confirmation is passed, the power mode of the vehicle body controller is switched to the power-on mode;
[0061] Step S250: After receiving the start operation from the operator, the vehicle body controller switches the power mode to the ignition mode.
[0062] When the user opens the vehicle with a pure mechanical key with only a key tooth, the body controller detects that the door is opened by the mechanical key, and then when valid identity information is obtained, the body controller sends an alarm message to the smart cockpit. After receiving the alarm message, the smart cockpit sends a verification request to the operator to obtain the verification information entered by the operator. After obtaining the verification information entered by the operator, the verification information is confirmed. After the confirmation is passed, the power mode of the body controller is switched to the power-on mode, and then the start operation of the operator is received. After receiving the start operation of the operator, the body controller switches the power mode to the ignition mode. This realizes the verification of the operator's identity when the vehicle is opened with a mechanical key with only a key tooth, and then starts the vehicle.
[0063] In some embodiments, the verification information is a startup password or voiceprint information or fingerprint information. The verification information can be a startup password or voiceprint information or fingerprint information. When the verification information is a startup password, the smart cockpit pops up a password input window and a corresponding text reminder on the display screen. The operator can enter the startup password on the display screen, and then the smart cockpit verifies and confirms the startup password. When the verification information is voiceprint information, the smart cockpit reminds the operator to input voice through a speaker, obtains the voice input by the operator through a microphone, extracts the voiceprint information, and then verifies the voiceprint information. When the startup password is fingerprint information, a voice reminder is issued or a text reminder is made on the display screen, allowing the operator to enter the fingerprint information on the fingerprint collector, and then the collected fingerprint information is verified and confirmed. In other embodiments, other verification information can also be used for identity verification.
[0064] In some embodiments, the following steps are also included:
[0065] The startup password set by the user is obtained through the diagnostic instrument and sent to the vehicle's smart cockpit or body controller.
[0066] When the startup password is used as verification information, when the sales company delivers the vehicle to the user, the startup password that the user wants to set is obtained through the diagnostic instrument, and then the diagnostic instrument imports the startup password into the smart cockpit Ouzhe body controller. In other embodiments, the user can also directly set verification information on the vehicle's smart cockpit or entertainment system, such as startup password, voiceprint information or fingerprint information.
[0067] In some embodiments, the smart cockpit confirms the received verification information specifically including the following steps:
[0068] The smart cockpit sends authentication request information to the body controller;
[0069] After receiving the serious request information, the body controller provides a random number to the smart cockpit;
[0070] The smart cockpit encrypts the verification information according to the random number provided by the body controller to obtain the authentication ciphertext and sends it to the body controller;
[0071] The body controller decrypts and verifies the received authentication ciphertext.
[0072] When the user sends verification information to the smart cockpit, the smart cockpit authenticates the verification information to the body controller; the smart cockpit sends authentication request information to the body controller, and when the body controller receives the authentication request information, it provides a random number to the body controller; the smart cockpit uses the random number provided by the body controller to encrypt the verification information to obtain the authentication ciphertext, and sends it to the body controller, and the body controller decrypts and verifies it after receiving the authentication ciphertext. In other embodiments, the smart cockpit can perform password verification with any controller and service platform in the vehicle, such as verification with the vehicle controller, verification with the gateway controller, or verification with the verification information stored on the service platform through TBOX, and when the verification passes, the verification results must be fed back to the body controller, and the body controller controls the jump of the power mode.
[0073] In some embodiments, when the vehicle body controller detects that the vehicle door is opened by a mechanical key and there is no identity validity information, sending an alarm message to the smart cockpit specifically includes the following steps:
[0074] When the body controller detects that the door is opened by a mechanical key and there is no identity validity information, the anti-theft alarm is triggered and an alarm message is sent to the smart cockpit.
[0075] When the body controller detects that the door is opened by a mechanical key and no valid identity information is obtained, the body controller sends out an anti-theft alarm to warn the operator. When the verification information is verified, the body controller cancels the anti-theft alarm.
[0076] In some embodiments, Figure 3 As shown, the vehicle authorization start method specifically includes the following steps:
[0077] 1) When the sales company delivers the vehicle to the user, the diagnostic instrument is used to help the user enter the startup password that the user expects to set;
[0078] 2) The vehicle is armed, that is, when it is locked from the outside, the user uses a mechanical key to open the door;
[0079] 3) If the BCM detects that the door is opened mechanically and there is no identity validity information, it triggers the anti-theft alarm and sends the alarm information to the smart cockpit;
[0080] 4) After ICM receives the alarm information, a password input window and corresponding text reminder pop up;
[0081] 5) After the user enters the startup password within the specified time, ICM begins password authentication with BCM:
[0082] 5.1) ICM sends authentication request information;
[0083] 5.2) BCM provides random numbers to ICM;
[0084] 5.3) ICM sends authentication ciphertext using the random number provided by BCM;
[0085] 5.4) BCM decrypts and verifies the authentication ciphertext after receiving it;
[0086] 6) If the password verification is successful, the BCM will release the anti-theft alarm and the power mode will switch to ON (powered on but not in a drivable state);
[0087] 7) When the user steps on the brake and changes gears within the allowed time window (such as 2 minutes), the BCM switches the power mode to Crank (ignition), and the vehicle enters the Ready state (drivable state).
[0088] This method allows users to start the vehicle with only a pure mechanical key (only the key teeth); at the same time, it provides the possibility for car companies to reduce key costs, and can replace radio frequency / Bluetooth remote control keys, or NFC cards, etc.

The operator can enter the startup password on the display screen, and then the smart cockpit 420 verifies and confirms the startup password. When the verification information is voiceprint information, the smart cockpit 420 reminds the operator to input voice through a speaker, obtains the voice input by the operator through a microphone, extracts the voiceprint information, and then verifies the voiceprint information. When the startup password is fingerprint information, a voice reminder is issued or a text reminder is made on the display screen, allowing the operator to enter the fingerprint information on the fingerprint collector, and then the collected fingerprint information is verified and confirmed. In other embodiments, other verification information can also be used for identity verification.
