The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0058] The following is based on Figures 1 to 5 A vehicle unlocking method provided by an embodiment of the present application is described.

[0059] The embodiment of the present application provides a vehicle unlocking method, which is applied to a body controller of a motorcycle, wherein the motorcycle has an electronic steering column lock, such as Figure 1 As shown, the method includes:

[0060] Step S100: Obtain a first key and a second key;

[0061] Step S200: performing an encryption operation on the first key to obtain a first checksum;

[0062] Step S300: sending a first message to the electronic steering column lock, where the first message includes a first checksum;

[0063] Step S400: In response to the second message, the second message includes a second checksum, and the second checksum is verified according to the second key. After the electronic steering column lock receives the first message, it obtains the first key and sends the second message if the first checksum is verified according to the first key. The second checksum is generated according to the second key after the electronic steering column lock obtains the second key.

[0064] Step S500: If the second checksum check passes, an unlocking instruction or a locking instruction is sent to the electronic steering column lock, so that the electronic steering column lock performs an unlocking operation or a locking operation accordingly.

[0065] In an embodiment of the present application, the body controller performs an encryption operation on the first key to obtain a first checksum, and sends a first message including the first checksum to the electronic steering column lock. After receiving the first message, the electronic steering column lock obtains the first key and verifies the first checksum according to the first key. If the verification passes, the electronic steering column lock sends a second message including a second checksum to the body controller. The body controller verifies the second checksum according to the second key. If the second checksum verification passes, it sends an unlocking instruction or a locking instruction to the electronic steering column lock, so that the electronic steering column lock performs the unlocking operation or the locking operation accordingly. The body controller and the electronic steering column lock perform two-way encryption authentication, and the unlocking operation or the locking operation is performed only after the verification passes, thereby improving the anti-theft performance of the motorcycle.

[0066] In some embodiments of the present application, the first key and the second key are stored in the EEPROM of the vehicle body controller and the electronic steering column lock.

[0067] In some embodiments of the present application, the unlock command is a request-to-unlock message with a CRC-32 checksum sent by the vehicle body controller. After the electronic steering column lock correctly interprets the message, the motor unlocks the vehicle. The position sensor confirms the retraction of the lock tongue, and a successful unlock signal with a CRC-32 checksum is sent to the vehicle body controller. Upon successful receipt of the signal, the vehicle body controller releases the power lock and sends the corresponding signal to the MCU, allowing the MCU to operate normally and the motorcycle to enter normal operating mode.

[0068] In some embodiments of the present application, the body controller requests the electronic steering column lock to activate the lock motor. After the electronic steering column lock is unlocked, the position sensor confirms that the lock tongue has been properly ejected and transmits a lock success signal to the body controller. Upon receiving the lock success signal, the body controller deactivates power to the lock motor and the motorcycle's ON position, completing the lock.

[0069] In some embodiments of the present application, the electronic steering column lock verifies the first checksum based on the first key. If the verification fails, a local alarm and an online alarm are triggered on the motorcycle. The body controller verifies the second checksum based on the second key. If the second checksum fails, a local alarm and an online alarm are triggered on the motorcycle.

[0070] In some embodiments of the present application, for “performing an encryption operation on the first key to obtain a first checksum” in step S200, step S200 includes:

[0071] Step S210: performing a byte replacement operation, a row shift operation, a column obfuscation operation, and a round key addition operation on the first key to obtain a first checksum.

[0072] In this embodiment, the vehicle body controller performs byte replacement operation, row shift operation, column obfuscation and round key addition operation on the first key based on the S-box encryption algorithm to obtain a first checksum.

[0073] In some embodiments of the present application, further explanation is given for “verifying the second checksum according to the second key” in step S400. Step S400 includes:

[0074] Step S410: decrypt the second checksum to obtain a first decryption result;

[0075] Step S420: If the first decryption result is the same as the second key, the verification is confirmed to be successful.

[0076] In this embodiment, the vehicle body controller decrypts the second checksum to obtain a first decryption result. If the first decryption result is the same as the second key, it is confirmed that the checksum has passed.

[0077] In some embodiments of the present application, the step S410 of “decrypting the second checksum to obtain a first decryption result” is further described. Step S410 includes:

[0078] Step S411: performing an inverse row shift operation, an inverse byte replacement operation, a round key addition operation, and an inverse column obfuscation operation on the second checksum to obtain a first decryption result.

[0079] In this embodiment, the vehicle body controller performs a reverse shift operation, a reverse byte replacement operation, a round key addition operation, and a reverse column obfuscation operation on the second checksum based on the S-box encryption algorithm to obtain a first decryption result.

[0080] In some embodiments of the present application, the step of “obtaining the first key and the second key” in step S100 is further described. Step S100 includes:

[0081] Step S110: Acquire motorcycle status information, which includes key position, vehicle speed, and motor speed;

[0082] Step S120: If the motorcycle status information meets the preset unlocking condition, obtain the first key and the second key;

[0083] Unlocking conditions include:

[0084] The key position is the ignition position or the off position;

[0085] The vehicle speed is zero;

[0086] The motor speed is zero.

[0087] In this embodiment, the body controller obtains the motorcycle status information and determines whether the motorcycle can be driven or stopped normally based on whether the key gear position, vehicle speed and motor speed meet the preset unlocking conditions. If the motorcycle can be driven or stopped normally, the first key or the second key is obtained to facilitate subsequent unlocking or locking operations, thereby improving the security of unlocking or locking the vehicle.

[0088] In some embodiments of the present application, when the driver opens the motorcycle door and activates the push-to-start switch, the body controller receives an action on the door feedback line and also receives an action on the push-to-start button, switching the motorcycle's gear to the ignition state. After the electronic control units on the remaining CAN lines perform a power-on self-test, the MCU sends a vehicle speed signal of 0, the motor speed signal of 0, and the steering wheel angle sensor sends a steering wheel angle signal of 30°. Once the body controller confirms that the vehicle speed, motor speed, and steering wheel angle signals are correct, it activates the 12V power supply to the lock motor of the electronic steering column lock.

[0089] In some embodiments of the present application, before "sending the first message to the electronic steering column lock" in step S300, the method further includes: sending a first power supply signal to the power supply terminal of the electronic steering column lock; and

[0090] In the case of "sending an unlocking command or a locking command to the electronic steering column lock" in step S500, a second power supply signal is synchronously sent to the power supply end of the lock motor, and the lock motor is used to perform an unlocking operation or a locking operation under the control of the electronic steering column lock.

[0091] In this embodiment, the output end of the vehicle body controller is connected to the power supply end of the electronic steering column lock and the power supply end of the lock motor, respectively. Before sending the first message, the vehicle body controller first sends a first power supply signal to the electronic steering column lock to power it, so as to facilitate two-way encrypted authentication with the electronic steering column lock. After the two-way encrypted authentication is passed, the vehicle body controller sends an unlocking command or a locking command to the electronic steering column lock, and simultaneously sends a second power supply signal to the power supply end of the lock motor to power the lock motor. After receiving the unlocking command or the locking command, the electronic steering column lock sends a control command to the lock motor, thereby controlling the lock motor to complete the unlocking operation or the locking operation. After the electronic steering column lock feeds back the status information of the completion of the unlocking operation or the locking operation to the vehicle body controller, the vehicle body controller stops sending the first power supply signal and the second power supply signal, and the electronic steering column lock and the lock motor are powered off.

[0092] The body controller controls the power supply for the electronic steering column lock and the lock motor, respectively, asynchronously unlocking the steering column. During functional interaction, the body controller only powers the lock motor when it needs to be driven to unlock or lock. At the same time, the body controller powers off the lock motor after the electronic steering column lock feedback function is completed. This reduces unnecessary static power consumption when the lock motor is not performing functional operations, extending the lifespan and unnecessary losses of the lock motor. The body controller provides a separate power supply output for the lock motor, while the electronic steering column lock provides control output for the lock motor. This ensures that the lock motor does not operate abnormally due to software design flaws or failures. For example, if the body controller is abnormally powered, the electronic steering column lock will not provide a control output; if the electronic steering column lock has an abnormal control output, the body controller will not provide a power output, thereby improving the functional safety level.

[0093] In some embodiments of the present application, the electronic steering column lock drives the lock motor to release the lock tongue, simultaneously detects the lock tongue position, and feeds back information such as the lock tongue position and unlock status to the vehicle body controller. Upon receiving the feedback signal, the vehicle body controller enables a flag associated with allowing vehicle movement. The motorcycle's ignition control module also displays the message "Vehicle Unlocked" on the screen in response to a broadcast signal. After all functions are executed, the electronic steering column lock enters a dormant state, or the vehicle body controller disconnects the power supply to the electronic steering column lock.

[0094] In some embodiments of the present application, when the driver performs a down-lock operation on a motorcycle, the body controller must detect that the push-to-start switch is off, the vehicle speed signal is 0, and the motor speed signal is 0. Simultaneously, the body controller requests the electronic steering column lock to perform two-way encrypted authentication. Within 5 seconds after verification, the body controller receives a message indicating that the steering wheel angle sensor is 30° for 5 consecutive frames and then requests the electronic steering column lock to drive the lock motor to lock. After the electronic steering column lock executes its function, it confirms through the position sensor that the lock tongue has been correctly ejected and sends a lock success signal to the body controller. Upon receiving the lock signal, the body controller cuts off power to the lock motor and the entire motorcycle's ON position.

[0095] In addition, the embodiment of the present application provides a vehicle unlocking method, which is applied to the electronic steering column lock of a motorcycle, and the motorcycle has a body controller, such as Figure 2 As shown, the method includes:

[0096] Step S1000: Responding to a first message sent by the vehicle body controller, obtaining a first key; the first message includes a first checksum, and the first checksum is generated by encrypting the first key after the vehicle body controller obtains the first key;

[0097] Step S2000: verifying the first checksum according to the first key;

[0098] Step S3000: If the first checksum verification passes, obtain the second key;

[0099] Step S4000: performing an encryption operation on the second key to obtain a second checksum;

[0100] Step S5000: Send a second message to the vehicle body controller, where the second message includes a second checksum, so that the vehicle body controller responds to the second message and verifies the second checksum according to the second key. If the second checksum passes the verification, an unlocking instruction is sent to the electronic steering column lock, so that the electronic steering column lock performs an unlocking operation.

[0101] In an embodiment of the present application, the body controller performs an encryption operation on the first key to obtain a first checksum, and sends a first message including the first checksum to the electronic steering column lock. After receiving the first message, the electronic steering column lock obtains the first key and verifies the first checksum according to the first key. If the verification passes, the electronic steering column lock sends a second message including a second checksum to the body controller. The body controller verifies the second checksum according to the second key. If the second checksum verification passes, it sends an unlocking instruction or a locking instruction to the electronic steering column lock, so that the electronic steering column lock performs the unlocking operation or the locking operation accordingly. The body controller and the electronic steering column lock perform two-way encryption authentication, and the unlocking operation or the locking operation is performed only after the verification passes, thereby improving the anti-theft performance of the motorcycle.

[0102] In some embodiments of the present application, further explanation is given for “verifying the first checksum according to the first key” in step S2000. Step S2000 includes:

[0103] Step S2100: decrypt the first checksum to obtain a second decryption result;

[0104] Step S2200: If the second decryption result is the same as the first key, the verification is confirmed to be successful.

[0105] In this embodiment, the electronic steering column lock decrypts the first checksum to obtain a second decryption result. If the second decryption result is the same as the first key, it is confirmed that the checksum has passed.

[0106] In some embodiments of the present application, the step S2100 of “decrypting the first checksum to obtain a second decryption result” is further described. Step S2100 includes:

[0107] Step S2110: performing an inverse row shift operation, an inverse byte replacement operation, a round key addition operation, and an inverse column obfuscation operation on the first checksum to obtain a second decryption result.

[0108] In this embodiment, the electronic steering column lock performs a reverse shift operation, a reverse byte replacement operation, a round key addition operation, and a reverse column obfuscation operation on the first checksum based on the S-box encryption algorithm to obtain a second decryption result.

[0109] In some embodiments of the present application, the step S4000 of "performing an encryption operation on the second key to obtain a second checksum" is further described. Step S4000 includes:

[0110] Step S4100: performing byte replacement operation, row shift operation, column obfuscation and round key addition operation on the second key to obtain a second checksum.

[0111] In this embodiment, the electronic steering column lock performs byte replacement operation, row shift operation, column obfuscation and round key addition operation based on the S-box encryption algorithm to obtain a second checksum.

After the electronic steering column lock receives the first message, it obtains the first key and sends the second message if the first checksum is verified according to the first key. The second checksum is generated according to the second key after the electronic steering column lock obtains the second key.

[0117] The instruction sending module 150 is used to send an unlocking instruction or a locking instruction to the electronic steering column lock if the second checksum verification passes, so that the electronic steering column lock performs an unlocking operation or a locking operation accordingly.
