Remote keyless starting method and system

Abstract

A remote keyless start method and system, belonging to the field of vehicle anti-theft, involves using a remote terminal to send a remote start command to a vehicle. The vehicle initiates a remote keyless start mode based on the remote start command. This mode includes controlling the BCM to unlock the doors and then switch the vehicle to the READY state. This application utilizes the remote terminal to directly control the vehicle's BCM to unlock the doors and switch the vehicle to the READY state, thereby achieving the technical effect of BCM shielding the key. The BCM no longer needs to determine whether to enter the READY state based on the secondary anti-theft authentication result between the key and the PEPS system. Instead, the BCM directly controls the vehicle to enter the READY state based on the remote start command, thereby achieving remote keyless start of the vehicle and improving user convenience in controlling the vehicle.

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] The PEPS system, or Passive Entry Passive Start, is a keyless entry and start system that allows the vehicle to be entered and started without a traditional mechanical key or remote key. When the driver steps into a designated area, the system recognizes the authorized driver and automatically opens the door. When the driver leaves the vehicle, the door locks automatically lock and enters anti-theft mode. The PEPS system works as follows:

[0003] 1. The user walks near a vehicle in the OFF state (the vehicle is powered off and the doors are locked) with a car key (such as a Bluetooth key). 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 vehicle key sends a high-frequency signal containing a fixed-code information pre-agreed with the PEPS system. Upon receiving the high-frequency signal, the high-frequency receiver verifies the fixed-code information contained in the high-frequency signal. If verification is successful, it notifies the BCM (Body Control Module) to unlock the doors and wake up the VCU (Vehicle Control Unit). The PEPS system's authentication based on the low-frequency trigger signal and the high-frequency signal is collectively referred to as primary anti-theft authentication.

[0005] 3. The user must 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 receiving the trigger signal from the door handle switch, the VCU controls the vehicle to power on and switches the vehicle state from OFF to ON (in the ON state, the vehicle powers on and the doors are unlocked). This completes the first-level anti-theft certification of the PEPS system.

[0006] 4. After the user enters the vehicle, 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 the VCU needs to be generated based on the fixed coding information used in the first-level anti-theft authentication stage. The VCU verifies the authentication key sent by PEPS and, after verification, determines whether the user has braked and started the vehicle within a certain period of time, and whether other necessary vehicle start-up actions have been completed. If so, the BCM is notified to switch the vehicle status from ON to READY, thus completing the second-level anti-theft authentication of the PEPS system.

[0007] Based on the aforementioned PEPS system, the existing remote door unlocking solution involves the user inputting a remote door unlock command via a mobile app. The communication control platform then transmits this remote door unlock command to the vehicle's TBOX. If the vehicle meets the preset enabling conditions, the TBOX then sends the remote unlock request command to the BCM and wakes up the VCU. The BCM then determines whether the vehicle is within the validity period of the primary anti-theft authentication system. If so, the BCM unlocks the door and collects a lock status signal. The lock status signal indicates whether the door unlocked successfully. If the door unlocking fails, the BCM also collects an unlock failure signal, which indicates the reason for the unlocking failure. The BCM then sends both the lock status signal and the unlock failure signal to the TBOX. The TBOX then transmits these two signals to the mobile app via the communication control platform, which displays them for the user to view. The door locking solution is similar to the door unlocking solution and will not be further elaborated here.

[0008] After the user remotely controls the unlocking of the car door through the mobile phone APP, if the user does not complete the second-level anti-theft authentication through the Bluetooth key within a specified time period (for example, within 2 minutes) after opening the car door and completing the first-level anti-theft authentication, the vehicle status cannot be switched to the READY state. In other words, if one user remotely unlocks the car 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 that the vehicle can be remotely authorized 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 start method, the remote keyless start 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 conjunction with the first aspect, in one embodiment, 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 vehicle unlock option and does not detect the key within the specified time period, the remote terminal sends a remote start command to the planning end.

[0015] In combination with the first aspect, in one embodiment, 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 again for the set time period.

[0017] In combination with the first aspect, in one embodiment, 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. The program exit pop-up window will display the remote keyless start mode exit.

[0019] In conjunction with the first aspect, in one embodiment, the vehicle side controls the BCM to unlock the vehicle 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 the 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 first-level 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;

[0025] The vehicle-side control module is used to control the vehicle 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.

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

[0028] In combination with the second aspect, in one embodiment, 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, 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 a specified time period, and the second exit condition is that the user locks the car within the specified time period, and the program exit pop-up window displays the remote keyless start mode exit.

[0034] The vehicle-side BCM is controlled by the remote terminal to directly unlock the door and switch the vehicle status to READY, 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 user control of the vehicle.

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

[0037] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, 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 this application clearer, the implementation methods of this 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 flowchart of an embodiment of the remote keyless starting method of this application. Figure 2 This is a functional module diagram of an embodiment of the remote keyless start system of this application. Figure 1 and Figure 2 As shown, remote keyless start methods include:

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

[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 switch 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 status to READY, 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 user control of the vehicle.

[0044] Furthermore, in one embodiment, the remote terminal 1 is used to send a remote start instruction to the vehicle, which specifically includes the following steps:

[0045] When the preconditions are valid and the triggering conditions occur, a remote control pop-up window will pop up via remote terminal 1. The precondition is that the vehicle is not in the READY state, and the triggering condition is that the user clicks the remote control app on 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 instruction 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 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 instruction to the vehicle. For example, when the user clicks on the remote APP on the remote terminal 1, a remote control pop-up window will pop 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 within two minutes, if there is no valid key in the car, you can start the vehicle by stepping on the brake (or performing other specified actions). This function is only valid once, please confirm whether it is turned on." If the user clicks "Yes", the remote control instruction is output, and the pop-up window is closed after the signal is successfully sent. If the user clicks "No", the remote control instruction 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 via the communication control platform, and the vehicle also reports vehicle status to Remote Terminal 1 via the communication control platform. The remote start command is typically received by the TBOX on the vehicle, which then sends vehicle status information to Remote Terminal 1. For example, the TBOX sends the TBOX_ShieldKeyDetection signal to the BCM. The signal value of this signal is 0x0: no request. The factory default value indicates a factory reset. The signal value of this signal is 0x1: ON, indicating remote keyless start mode is enabled and the BCM should shield the key and directly enter READY. The signal value of this signal is 0x0: OFF, indicating remote keyless start mode is disabled. The BCM sends the BCM_ShieldKeyDetection signal to the TBOX, indicating whether the BCM has activated remote keyless start mode. The TBOX then adds vehicle status information to the existing message, eliminating the need for additional parsing and custom data upload. Instead, the TBOX sends a remote control receipt to Remote Terminal 1 via the alarm channel. If the TBOX receives BCM_ShieldKeyDetection=ON feedback from the BCM within 1 second (calibrable) and confirms successful remote unlocking, the app prompts "Keyless start successful." If the TBOX does not receive BCM_ShieldKeyDetection=ON feedback from the BCM within 1 second (calibrable) or does not confirm successful unlocking, the app prompts "Keyless start failed" with the bcm-fail code. If the door is not moved, the BCM will lock the vehicle within 30 seconds.

[0050] Before the TBOX executes a task, if it detects any of the following three conditions, it can send the unlock and shield keys to the BCM according to the existing logic. The BCM will execute the remote unlock command normally without error if it receives the remote unlock command under unlock conditions. The shield key should reset the 2-minute timer without error. After the TBOX sends the command, it can simply check the feedback signal normally. Before the TBOX executes a task, "BCM_ShieldKeyDetection = 0x1 (keyless start)" and bcm_doorFLLockSts = 0x01 (indicating the main door lock is open)." Before the TBOX executes a task, "BCM_ShieldKeyDetection = 0x1 (keyless start)" and bcm_doorFLLockSts = 0x00 (indicating the main door lock is closed)." Before the TBOX executes a task, "BCM_ShieldKeyDetection = 0x0 (keyless start not possible)" and bcm_doorFLLockSts = 0x01 (indicating the main 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 start 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 again for the set time period.

[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 start method further includes:

[0056] After remote terminal 1 sends a remote start command to the vehicle, if the first or second exit condition occurs, a pop-up window will pop up on remote terminal 1 to exit the program. The first exit condition is that the vehicle status does not switch to the READY state within a specified time period. The second exit condition is that the user locks the vehicle within the specified time period. The pop-up window will display the exit of remote keyless start mode.

[0057] In this embodiment, the BCM executes the remote start command and provides feedback on the remote control status. 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). 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 the key starts the vehicle in this way, when leaving the vehicle, he or she must contact the owner to remotely lock and power off the vehicle through the remote APP. The logic of the remote control APP sending the remote unlocking command in keyless start mode is the same as that of normal remote unlocking.

[0060] Furthermore, in one embodiment, the vehicle side controls the BCM to unlock the vehicle doors and switch the vehicle state to the READY state according to the remote start command, specifically including 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 first-level anti-theft authentication is passed.

[0064] In this embodiment, the remote control command includes a low-frequency trigger signal and a high-frequency signal. Upon receiving the remote control command, the vehicle completes primary anti-theft authentication based on the low-frequency trigger signal and the high-frequency signal. After completing primary anti-theft authentication, the PEPS system automatically notifies the BCM to unlock the doors and wake up the VCU. In this embodiment, the remote control command does not directly control the BCM to unlock the doors. Instead, the system completes primary anti-theft authentication according to the existing PEPS system primary anti-theft authentication process, and the PEPS system then sends the door unlock command to the BCM. In another embodiment, the remote control command directly controls the BCM to unlock the doors, meaning that the BCM unlocks the doors and wakes the VCU without considering the results of the primary anti-theft authentication.

[0065] In a second aspect, an embodiment of the present application also provides a remote keyless start 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 this application. Figure 2 As shown, the remote keyless start system includes:

[0067] Remote terminal 1 is used to send remote start instructions 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. This mode includes controlling the BCM to unlock the door and then switch the vehicle state to the READY state.

[0069] In this embodiment, the remote terminal 1 controls the vehicle-side BCM to directly unlock the door and switch the vehicle status to READY status, 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 user control of 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 instruction to the vehicle. For example, when the user clicks on the remote APP on the remote terminal 1, a remote control pop-up window will pop 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 within two minutes, if there is no valid key in the car, you can start the vehicle by stepping on the brake (or performing other specified actions). This function is only valid once, please confirm whether it is turned on." If the user clicks "Yes", the remote control instruction is output, and the pop-up window is closed after the signal is successfully sent. If the user clicks "No", the remote control instruction 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 via the communication control platform, and the vehicle also reports vehicle status to Remote Terminal 1 via the communication control platform. The remote start command is typically received by the TBOX on the vehicle, which then sends vehicle status information to Remote Terminal 1. For example, the TBOX sends the TBOX_ShieldKeyDetection signal to the BCM. The signal value of this signal is 0x0: no request. The factory default value indicates a factory reset. The signal value of this signal is 0x1: ON, indicating remote keyless start mode is enabled and the BCM should shield the key and directly enter READY. The signal value of this signal is 0x0: OFF, indicating remote keyless start mode is disabled. The BCM sends the BCM_ShieldKeyDetection signal to the TBOX, indicating whether the BCM has activated remote keyless start mode. The TBOX then adds vehicle status information to the existing message, eliminating the need for additional parsing and custom data upload. Instead, the TBOX sends a remote control receipt to Remote Terminal 1 via the alarm channel. If the TBOX receives BCM_ShieldKeyDetection=ON feedback from the BCM within 1 second (calibrable) and confirms successful remote unlocking, the app prompts "Keyless start successful." If the TBOX does not receive BCM_ShieldKeyDetection=ON feedback from the BCM within 1 second (calibrable) or does not confirm successful unlocking, the app prompts "Keyless start failed" with the bcm-fail code. If the door is not moved, the BCM will lock the vehicle within 30 seconds.

[0072] Before the TBOX executes a task, if it detects any of the following three conditions, it can send the unlock and shield keys to the BCM according to the existing logic. The BCM will execute the remote unlock command normally without error if it receives the remote unlock command under unlock conditions. The shield key should reset the 2-minute timer without error. After the TBOX sends the command, it can simply check the feedback signal normally. Before the TBOX executes a task, "BCM_ShieldKeyDetection = 0x1 (keyless start)" and bcm_doorFLLockSts = 0x01 (indicating the main door lock is open)." Before the TBOX executes a task, "BCM_ShieldKeyDetection = 0x1 (keyless start)" and bcm_doorFLLockSts = 0x00 (indicating the main door lock is closed)." Before the TBOX executes a task, "BCM_ShieldKeyDetection = 0x0 (keyless start not possible)" and bcm_doorFLLockSts = 0x01 (indicating the main door lock is open)."

[0073] Furthermore, in one embodiment, the remote terminal 1 is configured to display a remote control pop-up window when a precondition is valid and a trigger condition occurs. The precondition is that the vehicle 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 "Vehicle Unlocked and Key Not Detected for a 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 instruction 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 a remote button on the mobile phone.

[0076] Furthermore, in one embodiment, the vehicle-side control module 2 is also used to determine that 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 further configured to, after sending a remote start command to the vehicle, display a pop-up program exit window if a first exit condition or a second exit condition occurs. The first exit condition is if the vehicle fails to switch to the READY state within a specified time period, and the second exit condition is if the user locks the vehicle within a specified time period. The pop-up program exit window displays the exit from remote keyless start mode.

[0079] In this embodiment, the BCM executes the remote start command and provides feedback on the remote control status. 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). 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 the key starts the vehicle in this way, when leaving the vehicle, he or she must contact the owner to remotely lock and power off the vehicle through the remote APP. The logic of the remote control APP sending the remote unlocking command in keyless start mode is the same as that of normal remote 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. Upon receiving the remote control command, the vehicle completes primary anti-theft authentication based on the low-frequency trigger signal and the high-frequency signal. After completing primary anti-theft authentication, the PEPS system automatically notifies the BCM to unlock the doors and wake up the VCU. In this embodiment, the remote control command does not directly control the BCM to unlock the doors. Instead, the PEPS system completes primary anti-theft authentication according to the existing PEPS primary anti-theft authentication process, and the PEPS system then sends the door unlock command to the BCM. In another embodiment, the remote control command directly controls the BCM to unlock the doors, meaning that the BCM does not consider the results of the primary anti-theft authentication and directly unlocks the doors and wakes the VCU.
