[0001] Embodiments of the present application relate to the technical field of vehicle control, and in particular, to a vehicle anti-theft method, device and storage medium. BACKGROUND

[0002] The anti-theft problem is particularly important for a vehicle in a parking state. Except for objective factors that cannot be controlled, technical vulnerabilities are the main factors leading to vehicle theft. Among the technical vulnerabilities, the thief mostly initiates a relay attack on the vehicle through an electronic interference device, or programs a new key through the OBD (On-Board Diagnostics Port, vehicle-mounted automatic diagnostic system port) and then starts the vehicle with the new key.

[0003] In the related art, UWB (Ultra-Wideband) or NFC (Near Field Communication) keys can be used to prevent the vehicle from being subjected to a relay attack. However, some low-end vehicle models may not have UWB keys and only support mobile phone Bluetooth keys, which are vulnerable to relay attacks. In the related art, the vehicle can also be monitored by a local security service, but this increases the cost of the vehicle owner. Therefore, how to avoid the vehicle from being subjected to a relay attack while controlling the cost of the vehicle owner and ensuring the anti-theft safety of the vehicle is a problem to be solved.

[0025] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will further describe the embodiments of the present application in combination with the drawings.

[0026] The present application provides a vehicle theft prevention method, please refer to Figure 1 , which shows a schematic diagram of an implementation environment of the method provided by an embodiment of the present application. The implementation environment can include: HCU (Hybrid Control Unit, vehicle controller) 11, BCM (Body Control Module, vehicle body controller) 12, ECU (Electronic Control Unit, electronic control unit) 13, ESP (Electronic Stability Program, electronic stability program controller) 14, IHU (Infotainment Head Unit, instrument display panel control system) 15, CALL Center (vehicle call center) 16 and TCU (Transmission Control Unit, transmission control unit) 17.

[0027] Optionally, the BCM 12 is configured to acquire the power-on and power-off state of the vehicle and send it to the HCU 11; the ECU 13 is configured to store the pre-stored VIN (Vehicle Identification Number) and authorized owner registration information, and send it to the HCU 11 when required by the HCU 11; the ESP 14 is configured to acquire the driving speed of the vehicle through the wheel speed sensor of the vehicle and send it to the HCU 11.

[0028] Exemplarily, the IHU 15 is used for a user to open / close a shift password protection function, the user inputs a shift password, the user selects to reset a vehicle verification password, a pop-up window is sent out to remind the user to open the shift password protection function, the user is prompted in the pop-up window to set a vehicle pre-stored password, the user is prompted through the pop-up window to input a VIN and owner registration information, the user is prompted through the pop-up window to input the shift password, the user is prompted through the pop-up window to provide a random number to the CALL Center 16, information that the user confirms to open the shift password protection function is sent to the HCU 11, and the VIN and owner registration information input by the user are transmitted back to the HCU 11 for verification.

[0029] In a possible implementation, the CALL Center 16 is used for authorization and adjustment of the owner registration information, the reset password operation is performed according to the random number provided by the user, and the reset vehicle verification password is sent to the HCU 11. The TCU 17 is used for obtaining gear information of the vehicle and allowing or limiting the vehicle to exit the P gear according to an instruction of the HCU 11. The HCU 11, the BCM 12, the ECU 13, the ESP 14, the IHU 15, the CALL Center 16 and the TCU 17 are communicatively connected through a wired or wireless network.

[0030] Based on the above Figure 1 The embodiment of the present application provides a vehicle theft prevention method as shown in the embodiment environment. Figure 2 The method is taken as an example applied to the HCU, and the method comprises steps 201-205.

[0031] In step 201, when the vehicle is powered on, the HCU obtains an opening / closing condition of a shift password protection function.

[0032] In a possible implementation, a setting item of the shift password protection function is located in an IHU of the vehicle, and before the user opens the shift password protection function, the opening / closing condition of the shift password protection function is in a closed state by default. Alternatively, the HCU can obtain a power-on / off state of the vehicle through a BCM, where the power-on / off state of the vehicle comprises vehicle power-on or vehicle power-off.

[0033] Exemplarily, when it is identified that the vehicle is powered on, if the user opens a setting item of the shift password protection function for the first time, the HCU sends out a pop-up window through the IHU to remind the user to open the shift password protection function. The way of reminding the user to open the shift password protection function includes but is not limited to: the pop-up window sent out by the IHU displays the text of “please open the shift password protection function”.

[0034] In a possible implementation, after the pop-up window reminding the user to open the shift password protection function is sent out, the HCU obtains the opening / closing condition of the shift password protection function, including: the HCU obtains the opening / closing condition of the shift password protection function through the IHU.

[0035] Optionally, if the user clicks the button for starting the gear password protection function on the display screen of the IHU, the IHU sends information of the user confirming starting of the gear password protection function to the HCU. After the HCU receives the information of the user confirming starting of the gear password protection function, the on-off state of the gear password protection function is switched to starting, and the HCU feeds back information that the gear password protection function has been started to the IHU. The IHU displays the information that the gear password protection function has been started.

[0036] Illustratively, when the vehicle is in the power-on state, in response to the user starting the gear password protection function for the first time, the user is prompted to set a vehicle pre-stored password; in response to receiving the vehicle pre-stored password set by the user, the user is prompted to input VIN and owner registration information; a user identity detection result is obtained based on the VIN and the owner registration information, the user identity detection result being used to indicate whether the user has password setting authority; and in response to obtaining the detection result that the user has password setting authority, the vehicle pre-stored password is confirmed as a vehicle verification password.

[0037] Optionally, after the user starts the gear password protection function for the first time, the HCU sends a pop-up window through the IHU to prompt the user to set a vehicle pre-stored password in the pop-up window. After receiving the vehicle pre-stored password set by the user, the IHU prompts the user to input VIN and owner registration information through the pop-up window.

[0038] In a possible implementation, after receiving the VIN and the owner registration information input by the user, the IHU transmits the VIN and the owner registration information input by the user back to the HCU for verification. The HCU obtains a user identity detection result based on the VIN and the owner registration information, wherein the user identity detection result is used to indicate whether the user has password setting authority.

[0039] Illustratively, the HCU obtains the user identity detection result based on the VIN and the owner registration information, including: the HCU reads the pre-stored VIN and authorized owner registration information in the ECU, compares the VIN input by the user with the pre-stored VIN, and compares the owner registration information input by the user with the authorized owner registration information.

[0040] In a possible implementation, if the VIN input by the user is consistent with the pre-stored VIN, and the authorized owner registration information contains the owner registration information input by the user, a detection result that the user has password setting authority is obtained; if at least one of the following conditions is met, a detection result that the user does not have password setting authority is obtained: the VIN input by the user is inconsistent with the pre-stored VIN, or the authorized owner registration information does not contain the owner registration information input by the user. Optionally, the authorization and adjustment of the owner registration information can be performed through the CALL Center of the vehicle.

[0041] In step 202, in response to the shift password protection function being turned on, the HCU acquires the driving speed and gear information of the vehicle, and the gear information includes P, R, N, D and S.

[0042] Exemplarily, after determining that the shift password protection function is turned on, the HCU acquires the driving speed and gear information of the vehicle, and the gear information includes P, R, N, D and S. In a possible implementation manner,

[0043] In a possible implementation manner, the HCU acquires the driving speed of the vehicle, including that the HCU can acquire the driving speed of the vehicle through the ESP. The ESP is located on the vehicle and is used to acquire the driving speed of the vehicle through the wheel speed sensor of the vehicle. The unit of the driving speed is usually kilometer / hour.

[0044] Optionally, the HCU acquires the gear information of the vehicle, including that the HCU can acquire the gear information of the vehicle through the TCU. The TCU is located on the vehicle and is used to determine the gear information of the vehicle according to the comprehensive data of the vehicle and the intention of the driver.

[0045] In step 203, in response to the driving speed of the vehicle being 0 and being in P, the HCU prompts the user to input the shift password.

[0046] Exemplarily, after acquiring the driving speed and gear information of the vehicle, if the driving speed of the vehicle is 0 and the vehicle is in P, the HCU prompts the user to input the shift password. Optionally, the way of prompting the user to input the shift password includes but is not limited to that the HCU sends a pop-up window through the IHU to prompt the user to input the shift password, and the user can directly input the shift password in the pop-up window. When the IHU receives the shift password input by the user, the IHU sends the shift password input by the user to the HCU.

[0047] In step 204, after receiving the shift password input by the user, the HCU acquires the verification result of the shift password, and the verification result of the shift password is used to indicate whether the verification of the shift password input by the user passes.

[0048] In a possible implementation manner, after receiving the shift password input by the user sent by the IHU, the HCU acquires the verification result of the shift password, and the verification result of the shift password is used to indicate whether the verification of the shift password input by the user passes. Optionally, the HCU acquires the verification result of the shift password, including: comparing the shift password input by the user with the vehicle verification password; and in response to the shift password input by the user being consistent with the vehicle verification password, acquiring the detection result that the verification of the shift password input by the user passes.

[0049] Exemplarily, the HCU compares the shift password input by the user with the vehicle verification password. If the shift password input by the user is consistent with the vehicle verification password, the HCU obtains a detection result that the shift password input by the user is verified. If the shift password input by the user is inconsistent with the vehicle verification password, the HCU obtains a detection result that the shift password input by the user is not verified.

[0050] Optionally, after the comparison between the shift password input by the user and the vehicle verification password is completed, in response to obtaining the detection result that the shift password input by the user is not verified, the user is prompted to input the shift password again. In a possible implementation, if the detection result that the shift password input by the user is not verified is obtained, the HCU prompts the user to input the shift password again in the following manner, which includes but is not limited to: the HCU sends a pop-up window through the IHU to prompt the user to input the shift password again, wherein the user can input the shift password again in the pop-up window of the IHU, or can directly select to reset the vehicle verification password in the pop-up window of the IHU.

[0051] Exemplarily, in response to obtaining the detection result that the shift password input by the user is not verified for four consecutive rounds, or receiving information that the user confirms to reset the vehicle verification password, a random string is generated, and the random string is used to obtain a reset vehicle verification password from an artificial service center of the vehicle. Each round includes a certain number of opportunities to input the shift password and a certain time interval between rounds.

[0052] In a possible implementation, the user can input a certain number of shift passwords in each round. If the shift password input by the user is not verified after a certain number of times, the next round of verification is started after a certain time interval. Optionally, the certain number of times and the certain time interval can be set according to experience, for example, the certain number of times can be set to four, and the certain time interval can be set to ten minutes.

[0053] Optionally, if the detection result that the shift password input by the user is not verified is obtained for four consecutive rounds, or information that the user confirms to reset the vehicle verification password, that is, information that the user selects to reset the vehicle verification password in the pop-up window, the HCU generates a random string, and the random string is used to obtain a reset vehicle verification password from an artificial service center of the vehicle.

[0054] In a possible implementation, after the HCU generates the random string, the HCU sends a pop-up window through the IHU, prompting the user to provide the random number to the CALL Center, and requiring the CALL Center to perform a password reset operation to obtain a reset vehicle verification password sent by the CALL Center, where the CALL Center uses a host USB (Universal Serial Bus, universal serial bus architecture) upgrade access authentication password.

[0055] In step 205, in response to the detection result that the shift password verification input by the user is passed, the HCU allows the vehicle to exit the P gear.

[0056] Optionally, after the acquisition of the verification result of the shift password is completed, in response to the detection result that the shift password verification input by the user is passed, the HCU allows the vehicle to exit the P gear through the TCU, that is, the user can perform the shift and start operation of the vehicle. If the detection result that the shift password verification input by the user is passed is not acquired, the vehicle is restricted from exiting the P gear through the TCU, that is, the user cannot perform the shift and start operation of the vehicle.

[0057] In a possible implementation, when the vehicle is powered off again, the on-off state of the shift password protection function before the vehicle is powered off is memorized. After the vehicle is powered on again, the on-off state of the shift password protection function before the vehicle is powered off is used.

[0058] The embodiment of the application acquires the on-off state of the shift password protection function when the vehicle is powered on, acquires the driving speed and gear information of the vehicle when the shift password protection function is turned on, prompts the user to input the shift password if the vehicle meets the conditions that the driving speed is 0 and the vehicle is in the P gear, judges whether the shift password input by the user is passed after the shift password input by the user is received, and allows the vehicle to exit the P gear if the shift password input by the user is passed. The identity verification step of the user before the vehicle is shifted and started is added on the basis of not increasing the implicit cost, the vehicle is prevented from being subjected to a relay attack, and the security of the vehicle is ensured.
