[0056] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0057] It should also be understood that the term “and / or” used in the specification and appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0058] As used in the specification and appended claims of this application, the term "if" can be interpreted as "when" or "uponce" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" can be interpreted as meaning "uponce it is determined" or "in response to determining" or "uponce [described condition or event] is detected" or "in response to detecting [described condition or event]", depending on the context.

[0059] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0060] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0061] With the development of intelligent vehicles, keyless entry systems (Passive Entry PassiveStart, PEPS) are installed in vehicles, and users can unlock the vehicle without using physical keys.

[0062] Specifically, the user can unlock the vehicle through the remote control key and / or mobile phone APP.

[0063] There are two ways to unlock the vehicle using the remote control key:

[0064] The first method is that the user clicks the unlock button on the remote control key, causing the remote control key to send a remote unlock signal (high frequency signal). After the PEPS in the vehicle receives the remote unlock signal, the PEPS decrypts the remote unlock signal and obtains the key ID and rolling code of the remote control key corresponding to the remote unlock signal. The PEPS identifies the key ID and rolling code, and if it determines that the key ID and rolling code are valid, the PEPS will unlock the vehicle. The operation of locking the vehicle is similar to that of unlocking the vehicle, and will not be repeated here.

[0065] The second method is that the user presses the unlock / lock switch on the door handle to make the vehicle send an unlock signal. The unlock signal triggers the capacitive switch to wake up the PEPS. The PEPS drives the low-frequency wire to trigger the remote control key to send a remote unlock signal. After the PEPS in the vehicle receives the remote unlock signal, the PEPS decrypts the remote unlock signal and obtains the key ID and rolling code of the remote control key corresponding to the remote unlock signal. The PEPS identifies the key ID and rolling code. If the key ID and rolling code are determined to be valid, the PEPS will unlock the vehicle.

[0066] The method of using a mobile phone APP to unlock a vehicle may include: after the user's mobile phone is close to the vehicle, the mobile phone and the vehicle are paired via Bluetooth. After Bluetooth authentication, the user clicks the unlock control on the mobile phone APP (Bluetooth key APP) to make the mobile phone send an unlock signal, and the PEPS in the vehicle unlocks the vehicle after receiving the unlock signal.

[0067] After the vehicle is unlocked, if the user's start operation is detected, the start operation is the operation of stepping on the brake and pressing the PEPS start / stop button (start operation), PEPS will drive the low-frequency antenna to trigger the remote control key to send a remote unlock signal. PEPS determines whether the remote control key is in the vehicle based on the field strength of the received remote unlock signal. When it is determined that the remote control key is in the vehicle, PEPS initiates anti-theft authentication with the vehicle control unit (VCU). If the anti-theft authentication passes, the vehicle power system will enter the running state from the start state, and the vehicle can be driven. If the anti-theft authentication fails, the vehicle cannot be started.

[0068] The anti-theft authentication may include: PEPS sends a random code to the vehicle control unit, and the vehicle control unit calculates the random code after receiving the random code to obtain a response code. The vehicle control unit sends the response code to PEPS, and PEPS calculates the response code after receiving the response code to obtain a solution code. If the solution code and the random code are the same, it is determined that the anti-theft authentication has passed. If the solution code and the random code are different, it is determined that the anti-theft authentication has not passed.

[0069] Although the above unlocking method can unlock the vehicle, if the user forgets to bring the remote control key and the mobile phone, or the remote control key is lost, the user will not be able to unlock the vehicle, let alone use the vehicle, which brings inconvenience to the user.

[0070] Based on the above problems, in order to ensure that the user can still open the vehicle when forgetting to bring the remote control key and the mobile phone, the present application designs a vehicle unlocking method, sets a manual password input function in the vehicle, and unlocks the vehicle by detecting the password manually input by the user. Through the method of the present application, the user can manually enter the password to unlock the vehicle, ensuring that the user can still use the vehicle normally when forgetting to bring the remote control key and the mobile phone, which brings convenience to the user.

[0071] The following combination Figure 1 The method for unlocking a vehicle according to an embodiment of the present application is described in detail.

[0072] Figure 1 A schematic flow chart of the vehicle unlocking method provided by the present application is shown, referring to Figure 1 , the method is described in detail as follows:

[0073] S101, when a vehicle is in a locked state, detecting a first operation performed by a user on the vehicle, wherein the first operation is used to trigger the vehicle to start detecting a password manually input by the user.

[0074] In this embodiment, when the vehicle is in a locked state, the vehicle doors are in a locked state, and modules such as the door handle module (DHM), PEPS, and vehicle electronic control unit (VCU) in the vehicle are in a dormant (low power consumption) state.

[0075] In this embodiment, the first operation may be an operation in which the user presses a certain area of ​​the vehicle, touches a certain area, or taps a certain area.

[0076] In one implementation, a touch area is provided on a door handle of a vehicle, and a method for detecting a first operation includes:

[0077] When a pressing operation of the user on the touch area is detected and the pressing operation lasts for a first preset time, it is determined that a first operation of the user on the vehicle is detected. The first preset time can be set as needed, for example, the first preset time can be set to 3 seconds or 4 seconds.

[0078] The touch area may include an unlocking sensing area and a locking sensing area. If it is detected that the user performs a pressing operation on the unlocking sensing area and the locking sensing area at the same time, and the pressing operation lasts for a first preset time, it is determined that a first operation performed by the user on the vehicle is detected.

[0079] Specifically, Figure 2 Schematic diagram of the door handle of the vehicle shown. The door handle is provided with a first sponge 1, a door handle module housing 2, a connecting harness 3, an unlocking sensing area 4, a printed circuit board 5 (Printed Circuit Board Assembly, PCBA), a locking sensing area 6, a second sponge 7 and a third sponge 8. The door handle of the vehicle is provided with an unlocking sensing area and a locking sensing area. Both the unlocking sensing area and the locking sensor are provided with a capacitive switch. When the user presses the unlocking sensing area, the capacitive switch is turned on. After the capacitive switch is turned on, it is determined that the user presses the unlocking sensing area. The unlocking sensing area and the locking sensor can also be provided with buttons. The unlocking sensing area 4 and the locking sensing area 6 are arranged on both sides of the door handle. For example, the locking sensing area 6 is arranged on the outside of the door handle, and the unlocking sensing area 4 is arranged on the inside of the door handle.

[0080] S102, obtaining an unlocking password input by the user in a manual password input area by touching, wherein the manual password input area is provided on the vehicle.

[0081] In this embodiment, the manual password input area on the vehicle can be set on the door handle, the outer body area, the headlight area, etc.

[0082] In one embodiment, a virtual number key is provided in the manual password input area, and the user inputs the unlocking password by touching the virtual number key, and the unlocking password is obtained by detecting the user's touching operation of the virtual number key.

[0083] For example, a touch operation of the user on the key "3" of the virtual numeric keypad is detected, and it is determined that the unlocking password input by the user includes 3.

[0084] S103: If the unlocking password matches the pre-stored password, the vehicle is controlled to switch from the locked state to the unlocked state.

[0085] In this embodiment, the manual start password set by the user is pre-stored, and the pre-stored manual start password is the pre-stored password. After detecting the unlocking password input by the user during this unlocking, the detected unlocking password is compared with the pre-stored password. If the unlocking password is the same as the pre-stored password, it is determined that the unlocking password input by the user this time is correct, and the vehicle can be unlocked.

[0086] Specifically, the method of setting a pre-stored password includes:

[0087] Method 1: The vehicle is provided with a password setting interface. After the user clicks the password setting control on the display screen, the display screen displays the password setting interface. The user enters the manual start password on the password setting interface.

[0088] Method 2: The user binds the vehicle to the mobile phone APP. After the user enters the manual start password through the mobile phone APP, the mobile phone sends the manual start password to the car telematics service system, and the car telematics service system encrypts the manual start password to obtain an encrypted password. The car telematics service system sends the encrypted password to the telematics terminal (Telematics Box, TBOX) on the vehicle, and TBOX transmits the encrypted password to PEPS via CAN. PEPS decrypts the encrypted password to obtain the manual start password, and PEPS saves the manual start password to obtain a pre-stored password.

[0089] After PEPS saves the manual start password, PEPS sends a message to TBOX indicating that the password has been successfully saved. After TBOX receives the permission setting information sent by the mobile phone APP, TBOX determines whether the user needs to enable the manual password start function based on the permission setting information. TBOX sends a first message to PEPS, and the first message indicates whether the manual password start function is enabled. After receiving the first message, PEPS turns on or off the manual password start function of the vehicle based on the first message.

[0090] It should be noted that the vehicle can only be unlocked by detecting the unlocking password manually entered by the user when the manual password start function of the vehicle is turned on.

[0091] In this embodiment, when the vehicle is in an unlocked state, the user can open the door and enter the vehicle.

[0092] In the present application, when the vehicle is in a locked state, it is detected whether the user has manually entered a password. If it is detected that the user has manually entered an unlocking password in the manual password input area, and the unlocking password matches the pre-stored password, the vehicle can be unlocked. In the present application, a manual password input area is provided on the vehicle for the user to manually enter a password, which increases the way to unlock the vehicle. Even if the user does not carry the remote control key and the mobile phone, the user can unlock the vehicle by manually entering the password, so that the user can still use the vehicle normally without carrying the remote control key and the mobile phone, which brings convenience to the user.

[0093] The above describes how to unlock the vehicle when the unlock password matches the pre-stored password. The following describes how to unlock the vehicle when the unlock password does not match the pre-stored password.

[0094] When the unlock password does not match the pre-stored password, the unlock password manually input by the user can continue to be detected until the preset password input upper limit is reached, and then the unlock password manually input by the user is stopped. After each unlock password is detected, the unlock password needs to be verified to determine whether the unlock password input by the user is correct. The vehicle is unlocked when the detected unlock password does not reach the preset password input upper limit and the unlock password matches the pre-stored password.

[0095] Specifically, after the above step S102, the above method may further include:

[0096] S201: If the unlocking password does not match the pre-stored password, obtain the i-th unlocking password manually input by the user, where i>1.

[0097] S202, if i is less than N, and the i-th unlocking password matches the pre-stored password, controlling the vehicle to switch from the locked state to the unlocked state, where N is the upper limit of the preset password input.

[0098] In this embodiment, i is less than N, indicating that the number of password inputs has not reached the preset password input upper limit, and the i-th unlocking password detected this time is a valid password. The i-th unlocking password is compared with the pre-stored password to see if they match. If the i-th unlocking password matches the pre-stored password, the vehicle can be unlocked.

[0099] S203: If the i-th unlocking password does not match the pre-stored password, obtaining the i+1-th unlocking password manually input by the user.

[0100] In this embodiment, if the i-th unlocking password does not match the pre-stored password, the i+1-th unlocking password input by the user next time can be obtained.

[0101] S204: If i+1 is equal to N, stop detecting the password manually input by the user.

[0102] In this embodiment, if i+1 is equal to N, it means that the password input has reached the preset password input upper limit, the i+1th unlocking password input this time is an invalid password, and the detection of the password manually input by the user can be stopped.

[0103] As an example, N is 3. After detecting the first unlocking password input by the user, if the first unlocking password matches the pre-stored password, the vehicle is controlled to enter the unlocked state. If the first unlocking password does not match the pre-stored password, the second unlocking password manually input by the user is detected. If the second unlocking password matches the pre-stored password, the vehicle is controlled to enter the unlocked state. If the second unlocking password does not match the pre-stored password, the third unlocking password manually input by the user is detected. The third unlocking password has reached the preset password input upper limit, the third unlocking password is an invalid password, and the detection of the password manually input by the user is stopped.

[0104] In the present application, setting an upper limit for password input can allow the user to enter the password multiple times to avoid the situation where the vehicle cannot be opened due to the user entering the wrong password; in addition, setting an upper limit for password input can also prevent illegal users from entering the correct password after unlimited trial and error, resulting in the vehicle being used by illegal users.

[0105] like Figure 3 As shown, in a possible implementation, the implementation of step S102 may include:

[0106] S1021, start detecting the password manually input by the user.

[0107] S1022: Detecting a password input operation performed by the user on a manual password input area on the vehicle by touching.

[0108] In this embodiment, the manual password input area includes Figure 2 The unlocking sensing area and the locking sensing area in the device are as follows. The user enters the unlocking password by touching the unlocking sensing area and the locking sensing area. Specifically, after the user touches the unlocking sensing area, the capacitive switch of the unlocking sensing area is turned on, and the password entered by the user is determined by detecting the opening and closing of the capacitive switch.

[0109] Specifically, the vehicle supports multiple manual password input methods, such as a decimal password input method and a Morse code input method.

[0110] For decimal password input: the number of times you touch the lock sensing area is determined, and after a password number is input, you touch the unlock sensing area to indicate that the input is complete. For example, to input 1 and 2, the user touches the lock sensing area once and then touches the unlock sensing area to indicate that the number "1" is input, and then the user touches the lock sensing area twice and then touches the unlock sensing area to indicate that the number "2" is input.

[0111] For Morse code input: the input of the two symbols dot (.) and dash (-) can be distinguished by the duration of touching the lock sensing area. Alternatively, the dot (.) can be represented by touching the lock sensing area, and the dash (-) can be represented by touching the unlock sensing area. In actual use, other touch methods can also be set to represent the two symbols dot (.) and dash (-).

[0112] S1023: Determine the unlocking password manually input by the user according to the password input operation.

[0113] In this embodiment, the unlocking password manually input by the user is determined based on the number of times and / or the duration of the touches on the manual password input area by the user, wherein the password input operation includes the number of times and / or the duration of the touches on the manual password input area.

[0114] In the present application, the unlocking password input by the user is obtained by detecting the password input operation of the user in the manual password input area. This method can quickly and accurately determine the unlocking password.

[0115] In a possible implementation, after detecting a first operation performed by a user on the vehicle, the door handle module is awakened, the door handle module wakes up the PEPS through the communication module, and the PEPS starts to wait for input of a manual password.

[0116] In one embodiment, after the door handle module wakes up the PEPS through the communication module, the method may further include:

[0117] PEPS starts to detect whether there is a key unlocking signal sent by the remote control key. If it is determined that the key unlocking signal of the vehicle is not detected, the unlocking password manually input by the user in the manual password input area is obtained, and manual password unlocking is started.

[0118] In one embodiment, after the door handle module wakes up the PEPS through the communication module, the method may further include:

[0119] PEPS starts to detect whether there is a key unlocking signal sent by the remote control key. If it is determined that the key unlocking signal of the vehicle is detected, the key unlocking signal is verified; if the key unlocking signal is a legal signal, the vehicle is controlled to switch from the locked state to the unlocked state; if the key unlocking signal is an illegal signal, the unlocking password manually input by the user in the manual password input area is obtained, and manual password unlocking is started.

[0120] In the present application, since unlocking the vehicle through a key unlocking signal is faster than unlocking the vehicle by manually entering a password by the user, the priority of remote control key unlocking is set higher than the priority of manual password unlocking. After PEPS is awakened, it first detects whether there is a key unlocking signal. If there is a key unlocking signal, the vehicle is unlocked according to the key unlocking signal. This can unlock the vehicle faster and improve the efficiency of vehicle unlocking.

[0121] In one possible implementation, in order to ensure the safety of the vehicle, a valid time for the unlocking password is set, and the vehicle can be started within the valid time of the unlocking password; if the valid time of the unlocking password is exceeded, the unlocking password becomes invalid and the vehicle cannot be started. If the user wants to start the vehicle, the user needs to re-enter the unlocking password.

[0122] like Figure 4 Specifically, after step S103, the method may further include:

[0123] S301, starting timing after the vehicle is switched to the unlocked state.

[0124] S302: If a start operation of the vehicle is detected within a second preset time period, control the vehicle to start.

[0125] In this embodiment, the second preset time length is set as needed. For example, the second preset time length can be set to 10 minutes or 15 minutes.

[0126] Specifically, if the vehicle startup operation is detected within the second preset time period, PEPS and VCU first perform anti-theft authentication, and the vehicle starts after the anti-theft authentication passes; if the anti-theft authentication fails, the vehicle startup is prohibited, and a vehicle fault prompt message can be displayed to facilitate the user to repair the vehicle.

[0127] S303: If no start operation of the vehicle is detected within the second preset time period, control the vehicle to enter a start-disabled state.

[0128] In this embodiment, if the start operation of the vehicle is not detected within the second preset time period, the unlocking password input this time becomes invalid and the vehicle cannot be started.

[0129] like Figure 5 As shown, in a possible implementation, the method of the present application may include:

[0130] S11, when the vehicle is in a locked state, a first operation is detected.

[0131] S12, determining whether a remote control key signal is detected and whether the vehicle has disabled a manual password start function.

[0132] S13: If no remote control key signal is detected and the vehicle starts with a manual password start function, the vehicle starts waiting for the unlocking password manually input by the user.

[0133] In another embodiment, if the remote control key signal is not detected and the manual password start function is not enabled for the vehicle, the vehicle is controlled to enter a dormant state.

[0134] S14, determining whether the password input waiting timeout has occurred.

[0135] S15: If the waiting time expires, the vehicle is controlled to enter a dormant state.

[0145] like Figure 6 As shown, in a possible implementation, the method of the present application may include:

[0146] The manual password input area includes a lock sensing area (input button) and an unlock sensing area (output button).

[0147] The user manually inputs the password in the manual password input area, and the microcontroller unit (MCU) in the door handle module (DHM) is used to detect the user's password input operation in the manual password input area, filter, de-jitter and other processing are performed on the signal of the password input operation, and obtain the unlocking password after determining that the detected password meets the preset length (for example, 6 characters).

[0148] MCU sends the unlocking password to PEPS through the communication module (TJA1028T chip). PEPS compares the pre-stored password with the unlocking password. When it is determined that the pre-stored password matches the unlocking password, it controls the vehicle to unlock.

[0149] The low voltage regulator (LDO) is connected to the MCU to provide power to the MCU. The vehicle control unit (VCU) performs anti-theft authentication with the PEPS before the vehicle is started to ensure the safety of the vehicle startup.

[0150] The telematics box (TBOX) on the vehicle is used to obtain the encrypted password set by the user from the vehicle telematics service system. The TBOX transmits the encrypted password to the PEPS via CAN. The PEPS decrypts the encrypted password to obtain the manual start password. The PEPS saves the manual start password to obtain the pre-stored password.
