[0045] The technical solutions of the present application will be described clearly and completely below in combination with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0046] As shown in the automobile electric door lock control method flow, the method steps include: Figure 1

[0047] Step S1, the door controller DCU receives the unlock / latch instruction of the domain controller PDC, and non-transiently stores the electric door lock state signal;

[0048] For example, in order to ensure that the electric door lock state signal is not lost after power failure or hibernation wake-up, an EEprom can be used as a storage device for non-transient storage.

[0049] Step S2, after the door controller DCU is woken up from hibernation or power failure is restored, the first electric door lock state signal before hibernation wake-up or power failure recovery is sent to the bus, and the current second electric door lock state signal is confirmed;

[0050] Specifically, the door controller DCU detects whether the automobile electric door lock is in the initial power-on state, for example, the door controller DCU is a new product for the first time, if the electric door lock is in the initial state, the door controller DCU sends the crash unlock state signal to the domain controller PDC.

[0051] Step S3, detecting whether the first electric door lock state signal stores the latch state signal or the unlock state signal, and combining whether the domain controller PDC sends the unlock / latch instruction, performing the corresponding automobile electric door lock unlocking / latching operation.

[0052] Specifically, if the first electric door lock state signal stores the door latching state signal, according to whether the domain controller PDC sends the unlock / latch instruction, the corresponding automobile electric door lock unlocking / latching operation is performed;

[0053] ​If the first electric door lock state signal stores a vehicle door unlocking state signal, corresponding vehicle electric door lock unlocking / locking operation is executed according to whether the domain controller PDC sends an unlocking / locking instruction.

[0054] For example, if the domain controller PDC sends an unlocking / locking instruction, the vehicle door controller DCU executes the unlocking / locking instruction sent by the domain controller PDC and sends a corresponding unlocking / locking state signal to the domain controller PDC.

[0055] If the vehicle door controller DCU does not detect that the domain controller PDC sends an unlocking / locking instruction, corresponding unlocking / locking instruction is executed according to the current vehicle door state and the crash unlocking state.

[0056] For example, if the vehicle door controller DCU does not detect that the domain controller PDC sends an unlocking / locking instruction, corresponding unlocking / locking instruction is executed according to the current vehicle door state and the crash unlocking state.

[0057] Specifically, the vehicle door controller DCU judges the current vehicle door state and the crash unlocking state.

[0058] If the current vehicle door is in a closed state and the crash unlocking signal is not triggered, the vehicle door controller DCU sends a vehicle door locking state signal to the domain controller PDC.

[0059] If the current vehicle door is in an open state, the vehicle door controller DCU sends a vehicle door unlocking state signal to the domain controller PDC.

[0060] If the current vehicle door is in a closed state and the crash unlocking signal is triggered, the vehicle door controller DCU sends a vehicle door unlocking state signal to the domain controller PDC.

[0064] As shown in the architecture diagram of the automobile electric door lock control system, specifically comprising: Figure 2

[0065] An electric door lock state signal storage module, the door controller DCU receives the unlock / latch instruction of the domain controller PDC, and non-transiently stores the electric door lock state signal;

[0066] An electric door lock state signal detection module, after the door controller DCU is woken up from hibernation or restored from power failure, sends the first electric door lock state signal before hibernation or power failure, and confirms the second electric door lock state signal at present;

[0067] An electric door lock unlocking / latching instruction execution module, detects whether the first electric door lock state signal storage is a latching state signal or an unlocking state signal, and combines whether the domain controller PDC sends the unlocking / latching instruction, to execute the corresponding automobile electric door lock unlocking / latching operation.

[0068] ​It is worth noting that, although only some basic functional modules are disclosed in the embodiments of the present application, it does not mean that the composition of the system is limited to the above basic functional modules, on the contrary, the meaning expressed by the embodiments is: on the basis of the above basic functional modules, those skilled in the art can add one or more functional modules to form infinite embodiments or technical solutions in combination with the prior art, that is, the system is open rather than closed, and the protection scope of the claims of the present application cannot be limited to the disclosed basic functional modules because the embodiments only disclose individual basic functional modules. At the same time, in order to facilitate description, the above device is described as various units and modules. Of course, when implementing the present application, the functions of the units and modules can be implemented in the same software and / or hardware.

[0069] The embodiments of the system described above are only illustrative, for example: the various functional modules, units or subsystems in the system can or can not be physically separated, or can or can not be physical units, i.e. they can be located in the same place or distributed to multiple different systems and their subsystems or modules. Those skilled in the art can select some or all of the functional modules, units or subsystems to achieve the purpose of the embodiments of the present application according to actual needs, and those skilled in the art can understand and implement them without creative labor.

[0070] As shown in the schematic diagram of the principle of the automobile electric door lock (electronic lock), the electronic lock (automobile electric door lock) has three states, which are electric opening state, reset state and collision unlocking state. Figure 3

[0071] 1. Electric opening position: when the door performs electric opening action, the motor needs to be driven to this position to completely open the door;

[0072] 2. Reset position: after the electric opening action is performed, the motor needs to be driven in reverse to this position to ensure that the door is closed next time; after the door lock is in the reset position and the door is closed, the door cannot be opened by the mechanical outer handle, but the mechanical inner handle can open the door, so this position is also a locking position. When the door is in the closed state and receives the locking or unlocking instruction, the door lock motor does not need to be driven, only the corresponding locking and unlocking state signals need to be fed back; when the DCU sends the unlocking state signal, the external opening signal is triggered by the outer handle at this time, the door can be opened by the motor drive; the effect is the same as the central locking position of the traditional door lock, the mechanical inner opening is effective, and the mechanical outer opening is ineffective.

[0073] ​3. Collision unlock position: can be unlocked by mechanical key or DCU collision unlock, can make the door lock in the collision unlock position, when the door lock is in this position, the car door can be opened by mechanical inner and outer pull handle; After the collision unlock is executed, the electric opening must be executed once, otherwise the car door cannot be executed. When the door lock is in the collision unlock position, the mechanical pull handle in the car is used to open the door, and the door lock is still in the collision unlock position. The effect is the same as that of the traditional central control unlock position, and the mechanical inner opening and the mechanical outer opening are effective.

[0074] In the embodiment, an implementation mode of the automobile electric door lock control method in a specific application scenario is provided, that is, a signal sending / receiving strategy of the automobile door lock:

[0075] 1. The electronic lock is in the collision unlock state when it is delivered, so when the vehicle is powered on for the first time, the DCU defaults to send an unlock state signal;

[0076] 2. When the DCU first receives the unlock / lock signal of the PDC, the actual unlock / lock instruction of the PDC is stored, and the current lock state is immediately stored in the EEprom. The state value is not lost after power failure or hibernation wake-up;

[0077] 3. When hibernation wakes up or power failure recovers power, the DCU first sends a frame of previously stored lock state signal on the bus, and synchronously confirms the current lock state;

[0078] 1) Before hibernation wakes up or power failure recovers power, the DCU stores the door lock state signal;

[0079] ①At this time, if the PDC sends an unlock / lock instruction, the corresponding unlock / lock state signal is immediately sent according to the actual instruction sent by the PDC;

[0080] ②At this time, if the PDC does not send an unlock / lock instruction, the current door state and the collision unlock state are judged. If the door is closed and the collision unlock signal is not triggered, the DCU sends the door lock signal; if the door is in the open state, the DCU sends the door unlock signal; if the door is closed and the collision unlock signal is triggered, the DCU sends the door unlock signal;

[0081] 2) When hibernation wakes up or power failure recovers power, the DCU stores the door unlock state signal;

[0082] ①At this time, if the PDC sends an unlock / lock instruction, the corresponding unlock / lock state signal is immediately sent according to the actual instruction sent by the PDC;

[0083] ②At this time, if the PDC does not send an unlock / lock instruction, the door state and the collision unlock state do not need to be judged, and the DCU continuously sends the door unlock signal.

[0084] As Figure 4 shown in the principle block diagram of the automobile electric door lock control circuit, the embodiment of the present application provides an automobile electric door lock control circuit, comprising:

[0085] A door controller DCU is used for executing the unlocking / locking instruction and / or feeding back the current unlocking / locking state signal of the electric door lock, the door controller DCU is connected in parallel on the vehicle CAN bus, and is used for receiving and sending the unlocking / locking instruction and the unlocking / locking state signal from the vehicle CAN bus; and the door controller DCU is connected with the automobile electric door lock, and is used for executing the unlocking / locking instruction.

[0086] A domain controller PDC is used for providing the control logic of the locking / unlocking of the electric door lock.

[0087] The automobile electric door lock control circuit executes the automobile electric door lock control method through the door controller DCU and the domain controller PDC.

[0088] The embodiment of the present application further provides an automobile electric door lock control device, and the automobile electric door lock control circuit is arranged in the device.
