[0002] The quietness of car door opening is one of the key indicators for evaluating car door quality. Currently, at the moment the door lock is released, the ratchet and pawl in the door lock may disengage under the action of the door sealing reaction force, producing abnormal noise, such as a noticeable "lock click".

[0003] However, most current methods suppress these abnormal noises by installing sound-absorbing layers in the door locks. But these sound-absorbing layers have the defect of reduced sound absorption performance after aging, resulting in poor quietness when the door is opened. Summary of the Invention

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the digit " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] The door lock control method and door opening control method provided in this application can be applied to electronic devices or software of electronic devices. The electronic device can be a terminal or a server. In some embodiments, the terminal can be a smartphone, tablet computer, laptop computer, desktop computer, etc.; the server can be configured as an independent physical server, or as a server cluster or distributed system composed of multiple physical servers. The software can be an application that implements the door lock control method and door opening control method, but is not limited to the above forms.

[0026] The control method for the car door lock and the control method for the car door opening provided in this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please see Figure 1 This application provides a method for controlling a car door lock. The car door lock includes a door lock assembly, which is installed on the car door. The door lock assembly includes a pawl, a ratchet, and a latch. The method for controlling the car door lock may include, but is not limited to, the following steps: Step S101: Receive unlock command while the door lock assembly is in the locked state; while in the locked state, the ratchet engages with the latch and pawl respectively; In practical implementation, during the door locking process, the ratchet drive device can be controlled to drive the ratchet in the locking direction, causing the ratchet to move in that direction until it engages with the latch, thus achieving a physical connection between the door and the vehicle body. Furthermore, to prevent the door from accidentally opening due to the ratchet's rebound force, the pawl drive motor can be controlled to drive the pawl in the locking direction, causing it to move in that direction until it engages with the ratchet, preventing the ratchet from rotating in the unlocking direction and thus keeping the door lock engaged. Optionally, the movement of the ratchet and pawl can include at least one of rotation or translation.

[0028] Optionally, for the ratchet, the locking direction can be the direction in which the ratchet engages with the latch during the locking process of the door lock assembly, and the unlocking direction can be the direction in which the ratchet disengages from the latch during the unlocking process of the door lock assembly. For the pawl, the locking direction can be the direction in which the pawl engages with the ratchet during the locking process of the door lock assembly, and the unlocking direction can be the direction in which the pawl disengages from the ratchet during the unlocking process of the door lock assembly.

[0029] In practice, when the door lock component is in the locked state, the unlocking command can be obtained by detecting the radio frequency signal related to the door lock status from the smart key, the trigger signal from the user pressing the door lock unlock button, or the network command related to the door lock status sent by the cloud server.

[0030] Step S102: In response to the unlocking command, control the ratchet drive device to drive the ratchet in the locking direction to reduce the meshing force between the pawl and the ratchet; the locking direction is the direction of movement in which the ratchet engages with the latch during the locking process of the door lock assembly; In practice, upon receiving an unlock command, the ratchet drive device can be controlled to continue driving the ratchet in the locking direction in response to the unlock command. Under the continued drive of the ratchet drive device, the ratchet can continue to move in the locking direction, thereby increasing its engagement with the latch. Correspondingly, the engagement between the pawl and the ratchet will decrease, thus reducing the meshing force between the ratchet and the pawl. Alternatively, the ratchet may not move, but under the continued drive of the ratchet drive device, its meshing force with the latch will increase, thereby reducing the meshing force between the pawl and the ratchet.

[0031] Step S103: In response to the satisfaction of the stop condition for the ratchet drive device to drive the ratchet in the locking direction, control the pawl drive device to drive the pawl to disengage from the ratchet and control the ratchet drive device to drive the ratchet to disengage from the latch, so as to unlock the door lock assembly.

[0032] Optionally, the satisfaction of the stopping condition can be used to characterize that the meshing force between the ratchet and the pawl has been reduced. In practice, the stopping condition for the ratchet drive device to drive the ratchet in the locking direction can be determined by monitoring the change in the meshing force between the pawl and the ratchet. For example, if the meshing force between the pawl and the ratchet is detected to be reduced, it can be determined that the stopping condition for the ratchet drive device to drive the ratchet in the locking direction is satisfied. Alternatively, the stopping condition for the ratchet drive device to drive the ratchet in the locking direction can be determined by the working condition of the ratchet drive device driving the ratchet in the locking direction. For specific implementation details, please refer to the relevant description below, which will not be described here.

[0033] When the above stopping conditions are met, the pawl drive device can be controlled to disengage the pawl from the ratchet at the first moment, and the ratchet drive device can be controlled to disengage the ratchet from the latch at the second moment, so as to unlock the door lock assembly.

[0034] Optionally, the first moment and the second moment can be the same moment or different moments. If the first moment and the second moment are different moments, the ratchet drive device can be controlled first to disengage the ratchet from the ratchet, and then the ratchet drive device can be controlled to disengage the ratchet from the latch, thus releasing the ratchet's movement restriction on the ratchet in advance and ensuring smooth door lock release. Alternatively, the ratchet drive device can be controlled first to disengage the ratchet from the latch, and then the ratchet drive device can be controlled to disengage the ratchet from the ratchet. In this case, to avoid additional noise caused by the ratchet colliding with the ratchet during its movement in the unlocking direction, the time interval between the first moment and the second moment can be limited to less than a preset time interval. Optionally, the preset time interval can be obtained through calibration.

[0035] In this embodiment of the application, in response to the unlocking command, the ratchet drive device is first controlled to drive the ratchet in the locking direction to reduce the meshing force between the pawl and the ratchet. This ensures that when the door lock is released, the ratchet and pawl will not disengage due to the door sealing reaction force, thus preventing abnormal noise and improving the quietness of door opening.

[0036] Optionally, the ratchet drive device and the pawl drive device described above can be the same drive device or different drive devices. In actual implementation, at least one type of drive device selected from motor drive device, electromagnetic drive device, hydraulic drive device, and pneumatic drive device can be used as the drive device for the ratchet and pawl.

[0037] In one embodiment, the stopping condition includes at least one of the following: the ratchet drive device drives the ratchet in the locking direction for a first duration, or the ratchet drive device drives the ratchet in the locking direction until the drive is blocked.

[0038] Optionally, the first duration can be obtained through calibration; the duration during which the ratchet drive device drives the ratchet in the locking direction to reach the first duration can be used to characterize that the meshing force between the pawl and the ratchet has been reduced.

[0039] In practice, the manifestation of drive obstruction can vary depending on the type of drive equipment. For motor-driven equipment, drive obstruction can manifest as stalling. For electromagnetic-driven equipment, drive obstruction can manifest as a sudden increase in current. For hydraulic-driven equipment, drive obstruction can manifest as the actuator stopping. For pneumatic-driven equipment, drive obstruction can manifest as the actuator stagnating or moving slowly.

[0040] The embodiments of this application determine that the above-mentioned stopping conditions are met by determining that the ratchet drive device drives the ratchet in the locking direction for a first duration and / or the ratchet drive device drives the ratchet in the locking direction until the drive is blocked. This can improve the effectiveness of reducing the meshing force between the pawl and the ratchet by controlling the ratchet drive device to drive the ratchet in the locking direction.

[0041] In one embodiment, step S103 above, in response to the satisfaction of the stopping condition of the ratchet drive device driving the ratchet in the locking direction, includes controlling the pawl drive device to disengage the pawl from the ratchet and controlling the ratchet drive device to disengage the ratchet from the latch, including: In response to the ratchet drive device driving the ratchet in the locking direction until the drive is blocked, the duration of the ratchet drive device being blocked is counted. In response to the second duration of the ratchet drive being obstructed, the ratchet drive is controlled to disengage the pawl from the ratchet and to disengage the ratchet from the latch.

[0042] In practice, after the ratchet drive device drives the ratchet in the locking direction until the drive is blocked, the ratchet drive device can continue to be powered for a period of time so that it can continue to work for a period of time in the state of blocked drive, so as to further stabilize the decreasing trend of meshing force between the ratchet and the pawl, thereby ensuring that the meshing force between the ratchet and the pawl is reduced.

[0043] Optionally, the second duration can be obtained through calibration; the duration during which the ratchet drive is obstructed can be used to characterize the reduced meshing force between the pawl and the ratchet.

[0044] This application embodiment, by responding to the ratchet drive device driving the ratchet in the locking direction until the drive is obstructed, and counting the duration of the obstruction; and responding to the duration of the obstruction reaching a second duration, controlling the pawl drive device to disengage the pawl from the ratchet, and controlling the ratchet drive device to disengage the ratchet from the latch, can further improve the effectiveness of reducing the meshing force between the pawl and the ratchet by controlling the ratchet drive device to drive the ratchet in the locking direction.

[0045] In one embodiment, the steps S103 above, including controlling the pawl drive device to disengage the pawl from the ratchet and controlling the ratchet drive device to disengage the ratchet from the latch, include: Simultaneously control the pawl drive device to disengage the pawl from the ratchet, and control the ratchet drive device to disengage the ratchet from the latch.

[0046] In actual implementation, when the above stopping conditions are met, the pawl drive device can be controlled to disengage the pawl from the ratchet, and the ratchet drive device can be controlled to disengage the ratchet from the latch. This not only ensures that the ratchet and pawl will not be forcibly disengaged due to the door sealing reaction force at the moment the door lock is released, thus preventing abnormal noise, but also enables the door lock to be released quickly.

[0047] Optionally, the aforementioned door lock can be a magnetic lock. The following is in conjunction with... Figure 2 Taking the magnetic lock as an example, the control process of the above-mentioned car door lock is explained: like Figure 2 As shown in Figure A, when the door lock assembly of the magnetic lock is in the locked state, the pawl release lever presses against the ratchet, and the ratchet engages with both the pawl and the latch. In response to receiving an unlocking command, the ratchet drive device can be controlled to drive the ratchet in its corresponding locking direction a to reduce the meshing force between the pawl and the ratchet, which can be understood as the magnetic lock over-engaging. During the process of the ratchet drive device driving the ratchet in the locking direction a, the ratchet remains engaged with the latch.

[0048] like Figure 2As shown in B, when the stopping condition of the ratchet drive device driving the ratchet in the locking direction is met, the pawl drive device can be controlled to drive the pawl in its corresponding unlocking direction b, so that the pawl release lever is lifted, the pawl disengages from the ratchet, and then, under the tension of the spring, the pawl can be released to... Figure 2 The pawl release position is indicated by C in the diagram.

[0049] like Figure 2 As shown in C, while controlling the pawl drive device to drive the pawl in the unlocking direction b, the ratchet drive device can be controlled to drive the ratchet in its corresponding unlocking direction c, so that it disengages from the latch and unlocks the door lock assembly; the ratchet can be reset to its initial position in the unlocked state under the drive of the ratchet drive device, which can be called the ratchet open position.

[0050] Please see Figure 3 This application also provides a method for controlling the opening of a vehicle door, which may include, but is not limited to, the following steps: Step S201: In response to receiving a door opening command while the door lock assembly is in a locked state, send an unlocking command to the door lock to execute the above-described door lock control method; Optionally, when the door lock assembly is in the locked state, a door opening command can be obtained by detecting radio frequency signals related to the door status from the smart key, trigger signals from the user's door opening button, or network commands related to the door status sent by the cloud server.

[0051] Furthermore, upon receiving a door opening command, an unlocking command can be sent to the door lock to execute the steps in each embodiment of the door lock control method described above.

[0052] Step S202: Control the door to open during the process of the pawl in the door lock assembly being disengaged from the ratchet by the pawl drive device and / or the ratchet in the door lock assembly being disengaged from the latch by the ratchet drive device.

[0053] In actual implementation, considering the efficiency of door opening and reducing the user's waiting time for the door to open, the door drive device can be controlled to open the door during the process of the pawl drive device driving the pawl in the door lock assembly to disengage from the ratchet, and / or the ratchet drive device driving the ratchet in the door lock assembly to disengage from the latch; optionally, the type of door drive device can refer to the types of pawl drive devices and ratchet drive devices mentioned above, which will not be elaborated here.

[0054] When the above-mentioned stopping conditions are met, the door drive device can be controlled to open the door simultaneously with the ratchet drive device disengaging the ratchet from the latch in the door lock assembly. This not only avoids the ratchet and pawl from hard disengaging due to the door sealing reaction force at the moment the door lock is released, thus preventing abnormal noise, but also avoids the time difference between the door opening under the door sealing reaction force and the door opening under the drive device due to the durability degradation of the door sealing performance, which would result in an uneven door opening process. This improves the quietness and smoothness of door opening.

[0055] This application embodiment, in response to receiving a door opening command while the door lock assembly is in a locked state, sends an unlocking command to the door lock to execute the aforementioned door lock control method; and controls the door opening during the process of the pawl drive device driving the pawl in the door lock assembly to disengage from the ratchet, and / or the ratchet drive device driving the ratchet in the door lock assembly to disengage from the latch, thereby improving the quietness and efficiency of door opening.

[0056] Optionally, the aforementioned door sealing reaction force can refer to the reverse thrust generated by the door sealing strip being squeezed and deformed when the door is closed due to the elasticity of its own material; the aforementioned durability degradation of the door sealing performance can refer to the degradation of the sealing performance of the door sealing strip due to repeated compression, environmental erosion (such as rainwater, ultraviolet rays), and other factors.

[0057] In one embodiment, controlling the opening of the vehicle door in step S202 above includes: Obtain the target sealing reaction force of the car door; Based on the relationship between sealing reaction force and door opening speed, determine the target speed that corresponds to the target sealing reaction force; Control the car door to open at the target speed.

[0058] In practice, the target sealing reaction force of the door can be calculated by detecting the degree of deformation of the door sealing strip during the door closing process; alternatively, the target sealing reaction force of the door can be obtained by detecting the electrical signal of the flexible piezoelectric film when the door is closed, and combining the correspondence between the electrical signal of the flexible piezoelectric film and the door sealing reaction force; optionally, the flexible piezoelectric film can be attached to the inner side of the door sealing strip or the sealing contact surface of the door frame.

[0059] Furthermore, the target sealing reaction force can be used to look up a preset table of correspondence between sealing reaction force and door opening speed to obtain the target speed; alternatively, the target sealing reaction force can be input into a model that has learned the correspondence between sealing reaction force and door opening speed to obtain the target speed.

[0060] It is worth mentioning that in the process of obtaining the target sealing reaction force of the vehicle door, a sealing reaction force can first be calculated based on the aforementioned deformation degree. Then, at least one parameter, such as ambient temperature or vehicle age, can be used to correct this sealing reaction force to obtain the target sealing reaction force. This can further improve the accuracy of obtaining the target sealing reaction force.

[0061] This application embodiment obtains the target sealing reaction force of the car door and, combined with the preset correspondence between the sealing reaction force and the car door opening speed, determines the target car door opening speed that matches the target sealing reaction force; then controls the car door to open at the target speed, so that the car door opening speed and the car door sealing reaction force form a dynamic match, thereby offsetting the interference of the car door sealing reaction force on the car door opening process and further improving the smoothness of the car door opening.

[0062] The following combination Figure 3 and Figure 4 Taking an electric door that uses a magnetic lock as its door lock, a ratchet drive device that is a ratchet drive motor, and a pawl drive device that is a pawl drive motor as examples, the control process for opening the aforementioned door will be explained: With the door closed, an unlock command can be sent to the door lock in response to an open command. Then, in response to the unlock command, the ratchet drive motor can be controlled to drive the ratchet in its corresponding locking direction 'a', reducing the meshing force between the pawl and the ratchet. During this process, the operating signal of the ratchet drive motor can be as shown in stage 'd' of signal curve 1. While the ratchet drive motor is driving the ratchet in its corresponding locking direction 'a', the stopping condition for the ratchet drive motor to drive the ratchet in the locking direction can be continuously monitored.

[0063] When the stopping condition is met, the ratchet drive motor can be controlled to drive the ratchet away from the latch in its corresponding unlocking direction. This process can also be understood as controlling the ratchet drive motor to reset, that is, controlling the ratchet drive motor to return from the current state to the preset initial state. During this process, the working signal of the ratchet drive motor can be as shown in stage e of signal curve 1. At the same time, the pawl drive motor can be controlled to drive the pawl away from the ratchet in its corresponding unlocking direction b. During this process, the working signal of the pawl drive motor can be as shown in stage f of signal curve 2. During the disengagement process of the ratchet from the latch, the position signal of the ratchet can be continuously monitored to determine whether the ratchet and latch have successfully disengaged; the position signal of the ratchet can be shown in signal curve 3. In actual implementation, the ratchet and latch can be determined to have successfully disengaged based on the sudden increase in the signal at stage g in signal curve 3 relative to the previous stage signal.

[0064] During the disengagement process of the pawl and ratchet, the position signal of the pawl can be continuously monitored to determine whether the disengagement is complete; the position signal of the pawl can be shown as signal curve 5. In actual implementation, the disengagement of the pawl and ratchet can be determined based on the sudden increase of the i-stage signal relative to the j-stage signal in signal curve 5. After the pawl and ratchet are completely disengaged, the pawl drive motor can be controlled to reset; during this process, the operating signal of the pawl drive motor can be shown as the k-stage signal in signal curve 2. During the process of the pawl disengaging from the ratchet and / or the ratchet disengaging from the latch, the door drive motor can be controlled to drive the door in the opening direction so that the door opens; during this process, the operating signal of the door drive motor can be as shown in the h stage signal of signal curve 4.

[0065] Optionally, when the above-mentioned stopping conditions are met, the pawl drive motor can be controlled to disengage the pawl from the ratchet, and the ratchet drive motor can be controlled to disengage the ratchet from the latch simultaneously, as shown in signal curves 1 and 2. The start times of stage f and stage e can be the same. In addition, during the process of simultaneously controlling the pawl drive motor to disengage the pawl from the ratchet and controlling the ratchet drive motor to disengage the ratchet from the latch, the door drive motor can be controlled to drive the door in the opening direction, as shown in signal curve 4. The start actuation signal of the door drive motor can be any signal located in the m~n interval of stage h in signal curve 4, and the duration of the m~n interval of stage h is equal to the maximum value of the duration of stage f and stage e. Optionally, the start actuation signal can be understood as the signal of the start time of the door drive motor's drive.

The vehicle door lock includes a door lock assembly, which is installed on the vehicle door. The door lock assembly includes a pawl, a ratchet, and a latch.
