Description

Technical Field

[0001] The present application relates to the field of vehicle anti-theft, and in particular to a remote keyless starting method and system. Background Art

[0002] PEPS system, namely Passive Entry Passive Start, is a keyless system that allows vehicles to enter and start without traditional mechanical keys and remote control keys. When the driver steps into the specified range, the system can identify the authorized driver of the vehicle and automatically open the door; when the driver leaves the vehicle, the door lock will automatically lock and enter the anti-theft state. The working principle of PEPS system is as follows:

[0003] 1. The user carries the car key (such as a Bluetooth key) and walks near a vehicle in the OFF state (the vehicle is powered off and the doors are locked in the OFF state). The car key sends a low-frequency signal to the low-frequency antenna. After the low-frequency antenna receives the signal, it sends a low-frequency trigger signal to the car key. After the car key receives the low-frequency trigger signal, the car key and the PEPS system complete the initial handshake verification.

[0004] 2. The car key sends out a high-frequency signal, which contains fixed-code information agreed with the PEPS system in advance. After receiving the high-frequency signal, the high-frequency receiver verifies the fixed-code information contained in the high-frequency signal, and when the verification is passed, it notifies the BCM (Body Control Module) to complete the door unlocking and wake up the VCU (Vehicle Control Unit). The authentication performed by the PEPS system based on the low-frequency trigger signal and the high-frequency signal is collectively referred to as the primary anti-theft authentication.

[0005] 3. The user needs to open the door handle within a certain period of time to enter the vehicle. When the door handle is opened, the door handle switch is triggered. After the VCU receives the trigger signal of the door handle switch, it controls the vehicle to power on and switches the vehicle state from OFF to ON (the vehicle is powered on and the doors are unlocked in the ON state). This completes the first-level anti-theft certification of the PEPS system.

[0006] 4. After the user enters the car, a second-level anti-theft authentication is performed between the car key and the VCU. During the second-level anti-theft authentication, the authentication key sent by PEPS to VCU needs to be generated according to the fixed coding information used in the first-level anti-theft authentication stage. VCU verifies the authentication key sent by PEPS, and after the verification is passed, determines whether the user has stepped on the brake to start the car within a certain period of time, and whether other necessary actions for starting the vehicle have been completed. If so, BCM is notified to switch the vehicle status from ON to READY. At this point, the second-level anti-theft authentication of the PEPS system is completed.

[0007] Based on the above PEPS system, the existing remote door unlocking solution is that the user inputs the remote door unlocking command through the mobile phone APP, and the communication control platform sends the remote door unlocking command to the TBOX on the vehicle side. If the vehicle meets the preset enabling conditions at this time, the TBOX sends the remote unlocking request command to the BCM and wakes up the VCU. The BCM determines whether it is within the validity period of the primary anti-theft certification. If so, the BCM controls the door unlocking and collects the lock status signal. The lock status signal indicates whether the door is unlocked successfully. When the door unlocking fails, the BCM also collects the unlocking failure signal. The unlocking failure signal indicates the reason for the unlocking failure. The BCM sends the lock status signal and the unlocking failure signal to the TBOX. The TBOX sends the above two signals to the mobile phone APP through the communication control platform. The mobile phone APP displays the above two signals for the user to view. The door locking solution is similar to the door unlocking solution, which will not be repeated here.

[0008] After the user remotely controls the door unlocking through the mobile phone APP, if the user does not complete the second-level anti-theft authentication through the Bluetooth key within the specified time period (for example, within 2 minutes) after opening the door and completing the first-level anti-theft authentication, the vehicle status cannot be switched to the READY state. In other words, if a user remotely unlocks the door through the mobile phone APP, even if another user can enter the car to complete the first-level anti-theft authentication, because he does not carry the Bluetooth key, he cannot complete the second-level anti-theft authentication between the VCU, and the vehicle authentication cannot be READY. If it cannot be READY, the vehicle cannot be driven away. Therefore, how to ensure that the vehicle status can still be switched to the READY state without carrying the Bluetooth key so as to remotely authorize the vehicle to drive away is the current problem to be solved. Summary of the invention

[0009] The present application provides a remote keyless starting method and system, which can solve the technical problem in the prior art that the BCM needs to determine whether to enter READY based on the secondary anti-theft authentication result between the key and the PEPS system, resulting in the vehicle being unable to enter READY when the key is not present.

[0010] In a first aspect, an embodiment of the present application provides a remote keyless starting method, the remote keyless starting method comprising:

[0011] The remote terminal sends a remote start command to the vehicle end, and the vehicle end starts the remote keyless start mode according to the remote start command. This mode includes controlling the BCM to unlock the door and then switch the vehicle state to the READY state.

[0012] In combination with the first aspect, in one implementation, the sending of the remote start instruction to the vehicle terminal by using the remote terminal specifically includes the following steps:

[0013] When the precondition is valid and the trigger condition occurs, a remote control pop-up window pops up through the remote terminal; the precondition is that the vehicle status is not READY, and the trigger condition is that the user clicks the remote control program on the remote terminal, and the remote control pop-up window displays the option of unlocking the vehicle and not detecting the key within the set time period;

[0014] After the user selects the option to unlock the vehicle and does not detect the key within a specified time period, the remote terminal sends a remote start command to the planning end.

[0015] In combination with the first aspect, in one implementation, the remote keyless starting method further includes:

[0016] After the vehicle status switches to the READY status, if the vehicle receives the remote start command again, the remote keyless start mode will be extended for the set time period again.

[0017] In combination with the first aspect, in one implementation, the remote keyless starting method further includes:

[0018] After the remote terminal sends a remote start command to the vehicle, if the first exit condition or the second exit condition occurs, the remote terminal will pop up a program exit pop-up window; the first exit condition is that the vehicle status has not switched to the READY status within the specified time period, and the second exit condition is that the user locks the vehicle within the specified time period, and the program exit pop-up window will display the remote keyless start mode exit.

[0019] In combination with the first aspect, in one implementation, the vehicle end controls the BCM to unlock the door and switch the vehicle state to the READY state according to the remote start command, specifically including the following steps:

[0020] After the vehicle receives the remote start command through TBOX, the result of the primary anti-theft authentication is set as authentication passed;

[0021] After the VCU detects that the user has opened the car door, it sets the result of the first-level anti-theft authentication as authentication passed;

[0022] The vehicle-side controls the BCM to shield the secondary anti-theft authentication result, and controls the BCM to switch the vehicle status to READY status when the primary anti-theft authentication is passed.

[0023] In a second aspect, an embodiment of the present application provides a remote keyless start system, the remote keyless start system comprising:

[0024] A remote terminal, which is used to send a remote start command to the vehicle end;

[0025] The vehicle-side control module is used to control the vehicle-side to start the remote keyless start mode according to the remote start command. This mode includes controlling the BCM to switch the vehicle state to the READY state after unlocking the door.

[0026] In conjunction with the second aspect, in one implementation, the remote terminal is used to pop up a remote control pop-up window when a precondition is valid and a trigger condition occurs; the precondition is that the vehicle state is not in a READY state, and the trigger condition is that the user clicks on the remote control program on the remote terminal, and the remote control pop-up window displays the option of unlocking the vehicle and not detecting the key within a set time period;

[0027] After the user selects the option to unlock the vehicle and does not detect the key within a specified time period, the remote terminal sends a remote start command to the planning end.

[0028] In combination with the second aspect, in one implementation, the vehicle-side control module is also used to determine whether the vehicle-side receives a remote start command again after the vehicle state is switched to the READY state, and then extend the remote keyless start mode for a set time period again.

[0029] In combination with the second aspect, in one embodiment, the remote terminal is also used to, after sending a remote start command to the vehicle end, if the first exit condition or the second exit condition occurs, a program exit pop-up window will pop up; the first exit condition is that the vehicle status has not switched to the READY status for more than a specified time period, and the second exit condition is that the user locks the vehicle within the specified time period, and the program exit pop-up window displays the remote keyless start mode exit.

[0030] In combination with the second aspect, in one implementation, the vehicle-side control module is further used to control the TBOX to set the result of the primary anti-theft authentication as authentication passed after receiving the remote start command;

The BCM no longer needs to judge whether to be READY based on the secondary anti-theft authentication result between the key and the PEPS system, but directly controls the vehicle to be READY based on the remote start command, thereby realizing remote keyless control start of the vehicle and improving the convenience of user control of the vehicle.

[0036] Figure 2 This is a schematic diagram of the functional modules of an embodiment of a remote keyless starting system of the present application. DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0039] In a first aspect, an embodiment of the present application provides a remote keyless starting method.

[0040] In one embodiment, referring to Figure 1 and Figure 2 , Figure 1 This is a flow chart of an embodiment of a remote keyless starting method of the present application. Figure 2 This is a functional module diagram of an embodiment of the remote keyless start system of the present application. Figure 1 and Figure 2 As shown, the remote keyless start method includes:

[0041] Step S1: Use the remote terminal 1 to send a remote start command to the vehicle end.

[0042] Step S2: The vehicle side starts the remote keyless start mode according to the remote start command. This mode includes controlling the BCM to unlock the door and then switching the vehicle state to the READY state.

[0043] In this embodiment, the remote terminal 1 controls the vehicle-side BCM to directly unlock the door and switch the vehicle state to the READY state, thereby achieving the technical effect of BCM shielding the key. The BCM no longer needs to judge whether to be READY based on the secondary anti-theft authentication result between the key and the PEPS system, but directly controls the vehicle to be READY based on the remote start command, thereby realizing remote keyless control start of the vehicle and improving the convenience of users controlling the vehicle.

[0044] Furthermore, in one embodiment, the above-mentioned use of the remote terminal 1 to send a remote start instruction to the vehicle terminal specifically includes the following steps:

[0045] When the precondition is valid and the trigger condition occurs, a remote control pop-up window pops up through the remote terminal 1. The precondition is that the vehicle state is not READY, and the trigger condition is that the user clicks the remote control program on the remote terminal 1, and the remote control pop-up window displays the option of unlocking the vehicle and not detecting the key within the set time period.

[0046] After the user selects the option to unlock the vehicle and does not detect the key within a specified time period, the remote terminal 1 sends a remote start command to the planning end.

[0047] In this embodiment, the precondition is that the current vehicle state must be non-READY regardless of whether the vehicle is powered on. The trigger condition is that the user clicks on the remote control program on the remote terminal 1, the remote terminal 1 can be a mobile phone, and the remote control program can be a remote APP on the mobile phone, or in the form of a remote button on the mobile phone.

[0048] When the current status of the vehicle is not READY and the user clicks on the remote APP icon on the mobile phone, the remote terminal 1 can send a remote control command to the vehicle. For example, when the user clicks on the remote APP on the remote terminal 1, a remote control pop-up window pops up to remind the user to confirm again whether to remotely start the vehicle. The specific method is to display in the remote control pop-up window "After turning on this function, the vehicle will be unlocked and the vehicle can be started by stepping on the brake (or performing other specified actions) without a valid key in the car within two minutes. This function is only valid once, please confirm whether to turn it on." If the user clicks "Yes", the remote control command is output, and the pop-up window is closed after the signal is successfully sent. If the user clicks "No", the remote control command is not output and the pop-up window is closed directly. The remote APP will also prompt "Keyless start execution successful" or "Keyless start execution failed" based on the feedback from the vehicle.

[0049] Remote terminal 1 sends the remote start command to the vehicle end through the communication control platform, and the vehicle end also feeds back the vehicle status to remote terminal 1 through the communication control platform. The vehicle end generally receives the remote enable command through TBOX, and TBOX sends the vehicle status information to remote terminal 1. For example, TBOX sends TBOX_ShieldKeyDetection signal to BCM, the signal value of which is described as 0x0: no request factory default value means restoring factory settings, the signal value of which is described as 0x1: ON means starting the remote keyless start mode, and BCM should shield the key and go directly to READY, the signal value of which is described as 0x0: OFF means turning off the remote keyless start mode. BCM sends BCM_ShieldKeyDetection signal to TBOX, which indicates whether BCM starts remote keyless start mode. TBOX adds vehicle status information to existing message, does not increase TBOX's parsing pressure, does not upload custom data, and sends remote control receipt to remote terminal 1 through alarm channel. TBOX receives BCM_ShieldKeyDetection=ON feedback from BCM within 1s (calibrable), and receives remote control unlocking success, then APP prompts "Keyless start execution successful". TBOX does not receive BCM_ShieldKeyDetection=ON feedback from BCM within 1s (calibrable), or does not receive unlocking success, then APP prompts "Keyless start execution failed" plus bcm-fail code. BCM will lock the door within 30s if the door is not moved.

[0050] Before TBOX executes a task, if the following three situations are detected, the unlocking and shielding keys can be sent to BCM according to the original logic. BCM will execute normally without error when receiving remote unlocking under unlocking conditions. The shielding key should reset the timer for 2 minutes without error. After TBOX sends it, it can detect the feedback signal normally. Before TBOX executes a task, "BCM_ShieldKeyDetection=0x1(keyless start) and bcm_doorFLLockSts=0x01(indicates that the main frame door lock is open)". Before TBOX executes a task, "BCM_ShieldKeyDetection=0x1(indicates that keyless start) and bcm_doorFLLockSts=0x00(indicates that the main frame door lock is closed)". Before TBOX executes a task, "BCM_ShieldKeyDetection=0x0(indicates that keyless start is not possible) and bcm_doorFLLockSts=0x01(indicates that the main frame door lock is open)".

[0051] Furthermore, in one embodiment, after the vehicle side receives the remote control command, it controls the BCM to unlock the vehicle door.

[0052] Furthermore, in one embodiment, the remote keyless starting method further includes:

[0053] After the vehicle status switches to the READY status, if the vehicle receives the remote start command again, the remote keyless start mode will be extended for the set time period again.

[0054] In this embodiment, after the vehicle enters the remote keyless start mode, if a remote start command is received again, the remote keyless start mode time can be extended.

[0055] Furthermore, in one embodiment, the remote keyless starting method further includes:

[0056] After the remote terminal 1 sends the remote start command to the vehicle, if the first exit condition or the second exit condition occurs, the remote terminal 1 pops up a pop-up window to exit the program. The first exit condition is that the vehicle state has not switched to the READY state for more than a specified time period, and the second exit condition is that the user locks the vehicle within the specified time period. The pop-up window to exit the program displays the remote keyless start mode exit.

[0057] In this embodiment, BCM executes the remote start command and feedbacks the remote control status, and the remote control APP displays relevant status information. If TBOX_ShieldKeyDetection=ON is detected, BCM_ShieldKeyDetection=ON is fed back. During the validity period of a single authorized start, opening and closing any door will no longer trigger the key search behavior (there is no key in the car itself), and when the user steps on the brake and enters READY, the key is directly sent to the car. After entering READY, the key detection function is not blocked, but the key detection alarm reminder is not triggered.

[0058] If the first exit condition or the second exit condition occurs, the remote keyless start mode will feedback BCM_ShieldKeyDetection=OFF (repeating up and down ready within 2 minutes will not affect this function).

[0059] If a user who does not carry a key starts the vehicle in this way, when leaving the vehicle, he or she must contact the owner to remotely control the vehicle to lock and power off through the remote APP. The logic of the remote control unlocking command sent by the remote control APP in keyless start mode is the same as the normal remote control unlocking.

[0060] Further, in one embodiment, the vehicle end controls the BCM to unlock the door and switch the vehicle state to the READY state according to the remote start command, which specifically includes the following steps:

[0061] After the vehicle receives the above remote start command through TBOX, the result of the primary anti-theft authentication is set as authentication passed.

[0062] After the VCU detects that the user has opened the car door, it sets the result of the first-level anti-theft authentication as authentication passed.

[0063] The vehicle-side controls the BCM to shield the secondary anti-theft authentication result, and controls the BCM to switch the vehicle status to READY status when the primary anti-theft authentication is passed.

[0064] In this embodiment, the remote control command includes a low-frequency trigger signal and a high-frequency signal. After the vehicle receives the remote control command, the primary anti-theft authentication is completed according to the low-frequency trigger signal and the high-frequency signal contained therein. After completing the primary anti-theft authentication, the PEPS system will automatically notify the BCM to unlock the door and wake up the VCU. In this embodiment, the remote control command does not directly control the BCM to unlock the door, but completes the primary anti-theft authentication of the PEPS system according to the existing PEPS system primary anti-theft authentication process, and the PEPS system sends a door unlocking command to the BCM. In another embodiment, the remote control command directly controls the BCM to unlock the door, that is, the BCM does not need to consider the result of the primary anti-theft authentication, and directly unlocks the door and wakes up the VCU.

[0065] In a second aspect, an embodiment of the present application also provides a remote keyless starting system.

[0066] In one embodiment, referring to Figure 2 , Figure 2 This is a functional module diagram of an embodiment of the remote keyless start system of the present application. Figure 2 As shown, the remote keyless start system includes:

[0067] The remote terminal 1 is used to send a remote start instruction to the vehicle end.

[0068] The vehicle-side control module 2 is used to control the vehicle-side to start the remote keyless start mode according to the remote start command. The mode includes controlling the BCM to switch the vehicle state to the READY state after unlocking the door.

[0069] In this embodiment, the remote terminal 1 controls the vehicle-side BCM to directly unlock the door and switch the vehicle state to the READY state, thereby achieving the technical effect of BCM shielding the key. The BCM no longer needs to judge whether to be READY based on the secondary anti-theft authentication result between the key and the PEPS system, but directly controls the vehicle to be READY based on the remote start command, thereby realizing remote keyless control start of the vehicle and improving the convenience of users controlling the vehicle.

[0070] When the current status of the vehicle is not READY and the user clicks on the remote APP icon on the mobile phone, the remote terminal 1 can send a remote control command to the vehicle. For example, when the user clicks on the remote APP on the remote terminal 1, a remote control pop-up window pops up to remind the user to confirm again whether to remotely start the vehicle. The specific method is to display in the remote control pop-up window "After turning on this function, the vehicle will be unlocked and the vehicle can be started by stepping on the brake (or performing other specified actions) without a valid key in the car within two minutes. This function is only valid once, please confirm whether to turn it on." If the user clicks "Yes", the remote control command is output, and the pop-up window is closed after the signal is successfully sent. If the user clicks "No", the remote control command is not output and the pop-up window is closed directly. The remote APP will also prompt "Keyless start execution successful" or "Keyless start execution failed" based on the feedback from the vehicle.

[0071] Remote terminal 1 sends the remote start command to the vehicle end through the communication control platform, and the vehicle end also feeds back the vehicle status to remote terminal 1 through the communication control platform. The vehicle end generally receives the remote enable command through TBOX, and TBOX sends the vehicle status information to remote terminal 1. For example, TBOX sends TBOX_ShieldKeyDetection signal to BCM, the signal value of which is described as 0x0: no request factory default value means restoring factory settings, the signal value of which is described as 0x1: ON means starting the remote keyless start mode, and BCM should shield the key and go directly to READY, the signal value of which is described as 0x0: OFF means turning off the remote keyless start mode. BCM sends BCM_ShieldKeyDetection signal to TBOX, which indicates whether BCM starts remote keyless start mode. TBOX adds vehicle status information to existing message, does not increase TBOX's parsing pressure, does not upload custom data, and sends remote control receipt to remote terminal 1 through alarm channel. TBOX receives BCM_ShieldKeyDetection=ON feedback from BCM within 1s (calibrable), and receives remote control unlocking success, then APP prompts "Keyless start execution successful". TBOX does not receive BCM_ShieldKeyDetection=ON feedback from BCM within 1s (calibrable), or does not receive unlocking success, then APP prompts "Keyless start execution failed" plus bcm-fail code. BCM will lock the door within 30s if the door is not moved.

[0072] Before TBOX executes a task, if the following three situations are detected, the unlocking and shielding keys can be sent to BCM according to the original logic. BCM will execute normally without error when receiving remote unlocking under unlocking conditions. The shielding key should reset the timer for 2 minutes without error. After TBOX sends it, it can detect the feedback signal normally. Before TBOX executes a task, "BCM_ShieldKeyDetection=0x1(keyless start) and bcm_doorFLLockSts=0x01(indicates that the main frame door lock is open)". Before TBOX executes a task, "BCM_ShieldKeyDetection=0x1(indicates that keyless start) and bcm_doorFLLockSts=0x00(indicates that the main frame door lock is closed)". Before TBOX executes a task, "BCM_ShieldKeyDetection=0x0(indicates that keyless start is not possible) and bcm_doorFLLockSts=0x01(indicates that the main frame door lock is open)".

[0073] Further, in one embodiment, the remote terminal 1 is used to pop up a remote control pop-up window when the precondition is valid and the trigger condition occurs. The precondition is that the vehicle state is not in the READY state, and the trigger condition is that the user clicks the remote control program on the remote terminal 1, and the remote control pop-up window displays the option of unlocking the vehicle and not detecting the key within the set time period.

[0074] After the user selects the option to unlock the vehicle and does not detect the key within a specified time period, the remote terminal 1 sends a remote start command to the planning end.

[0075] In this embodiment, the precondition is that the current vehicle state must be non-READY regardless of whether the vehicle is powered on. The trigger condition is that the user clicks on the remote control program on the remote terminal 1, the remote terminal 1 can be a mobile phone, and the remote control program can be a remote APP on the mobile phone, or in the form of a remote button on the mobile phone.

[0076] Furthermore, in one embodiment, the vehicle-side control module 2 is also used to determine whether the vehicle-side receives a remote start command again after the vehicle state is switched to the READY state, and then extend the remote keyless start mode for a set time period again.

[0077] In this embodiment, after the vehicle enters the remote keyless start mode, if a remote start command is received again, the remote keyless start mode time can be extended.

[0078] Furthermore, in one embodiment, the remote terminal 1 is also used to pop up a program exit pop-up window after sending a remote start command to the vehicle end if the first exit condition or the second exit condition occurs. The first exit condition is that the vehicle state has not switched to the READY state for more than a specified time period, and the second exit condition is that the user locks the vehicle within the specified time period, and the program exit pop-up window displays the remote keyless start mode exit.

[0079] In this embodiment, BCM executes the remote start command and feedbacks the remote control status, and the remote control APP displays relevant status information. If TBOX_ShieldKeyDetection=ON is detected, BCM_ShieldKeyDetection=ON is fed back. During the validity period of a single authorized start, opening and closing any door will no longer trigger the key search behavior (there is no key in the car itself), and when the user steps on the brake and enters READY, the key is directly sent to the car. After entering READY, the key detection function is not blocked, but the key detection alarm reminder is not triggered.

[0080] If the first exit condition or the second exit condition occurs, the remote keyless start mode will feedback BCM_ShieldKeyDetection=OFF (repeating up and down ready within 2 minutes will not affect this function).

[0081] If a user who does not carry a key starts the vehicle in this way, when leaving the vehicle, he or she must contact the owner to remotely control the vehicle to lock and power off through the remote APP. The logic of the remote control unlocking command sent by the remote control APP in keyless start mode is the same as the normal remote control unlocking.

[0082] Furthermore, in one embodiment, the vehicle-side control module 2 is further configured to control the TBOX to set the result of the primary anti-theft authentication as authentication passed after receiving the remote start command.

[0083] After the VCU detects that the user has opened the car door, it sets the result of the first-level anti-theft authentication as authentication passed.

[0084] The vehicle-side control module 2 is also used to control the BCM to shield the secondary anti-theft authentication result, and control the BCM to switch the vehicle state to the READY state when the primary anti-theft authentication is passed.

[0085] In this embodiment, the remote control command includes a low-frequency trigger signal and a high-frequency signal. After the vehicle receives the remote control command, the primary anti-theft authentication is completed according to the low-frequency trigger signal and the high-frequency signal contained therein. After completing the primary anti-theft authentication, the PEPS system will automatically notify the BCM to unlock the door and wake up the VCU. In this embodiment, the remote control command does not directly control the BCM to unlock the door, but completes the primary anti-theft authentication of the PEPS system according to the existing PEPS system primary anti-theft authentication process, and the PEPS system sends a door unlocking command to the BCM. In another embodiment, the remote control command directly controls the BCM to unlock the door, that is, the BCM does not need to consider the result of the primary anti-theft authentication, and directly unlocks the door and wakes up the VCU.
