[0059] Example 1

[0060] Figure 1 This is a flowchart of a suction lock anti-pinch control method provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of anti-pinch control of automotive suction locks. The method can be executed by a suction lock anti-pinch control device, which can be implemented in hardware and / or software, and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0061] S110. Acquire the switch signal and motor Hall signal of the target latching lock, and determine the current latching position of the target latching lock based on the switch signal and motor Hall signal.

[0062] The suction lock is an automatically closing door lock that can be installed on a car door. The target suction lock is the controlled object of this suction lock anti-pinch control method. The switch signal is a signal indicating the open / closed state of the target suction lock, and may include a suction lock pawl signal, a ratchet signal, and a door open signal, etc. The motor Hall signal is the rotor position signal of the motor driving the target suction lock.

[0063] In this embodiment, the switching signal of the target locking mechanism and the Hall signal of the motor can be acquired in real time through a signal acquisition device.

[0064] Preferably, the control device for the target latching lock can acquire the pawl signal, ratchet signal and door opening signal of the target latching lock in real time through a set signal acquisition module, and acquire the Hall signal of the motor of the target latching lock in real time through a Hall acquisition module.

[0065] Furthermore, the current engagement position refers to the position of the target latch during its entire journey from fully open to fully closed. Throughout the entire journey from fully open to fully closed, the switch signal and motor Hall effect signal differ for each engagement position. For example, when the target latch is fully open, the pawl signal, ratchet signal, and door open signal are all triggered; when the target latch is fully closed, only the pawl and ratchet signals are triggered. The magnitude of the motor Hall effect signal varies depending on the position of the target latch between fully open and fully closed. Therefore, the current engagement position of the target latch can be determined based on the switch signal and the motor Hall effect signal.

[0066] S120. Determine the energy increment of the target latching lock from the start of latching to the current latching position, and determine the energy threshold corresponding to the current latching position.

[0067] The closing process of the target latch lock involves an increase in energy. Under normal circumstances, the energy increment during closing should be within a stable range. If there is resistance during closing, the energy increment will jump. Therefore, by tracking the changes in the magnitude of the energy increment during the closing process of the target latch lock, it is possible to determine whether a user's hand is trapped.

[0068] In this embodiment, the energy increment is the accumulated energy increment when the target latching lock reaches the current latching position during the latching process, and the energy threshold is the maximum value of the preset energy increment corresponding to the current latching position. The target latching lock can correspond to different energy thresholds at different latching positions.

[0069] Preferably, to determine the energy increment of the target latching lock from the start of latching to the current latching position, the energy increment can be characterized by acquiring the current signal of the motor driving the target latching lock.

[0070] S130. If the energy increment is greater than the energy threshold corresponding to the current engagement position, then stop the engagement action of the target engagement lock.

[0071] In this embodiment, if the energy increment is greater than the energy threshold corresponding to the current engagement position, it can be determined that a pinching situation may occur. When this situation occurs, anti-pinch processing can be triggered, and the control device of the target engagement lock can send a control signal to the motor of the target engagement lock to stop the engagement action of the target engagement lock.

[0072] Furthermore, if a capacitor switching signal is detected inside the door handle, the closing action of the target latching lock will be stopped.

[0073] In this embodiment, the capacitor switching signal inside the door handle is the capacitor switching signal collected from the door handle of the vehicle door on which the target magnetic lock is installed. When the capacitor switching signal inside the door handle is collected, it can be determined that there may be a situation where the door handle is being pulled. Therefore, if the energy increment is greater than the energy threshold corresponding to the current magnetic position, it can be determined that a pinch situation may occur; if the capacitor switching signal inside the door handle is collected, it can be determined that there may be a situation where the door handle is being pulled. When one of the above two situations occurs, the anti-pinch processing can be triggered, and the control device of the target magnetic lock can send a control signal to the motor of the target magnetic lock to stop the magnetic lock's magnetic action.

[0074] Furthermore, when the number of times the target latching lock stops latching exceeds a set threshold, the target latching lock is controlled to complete the latching action.

[0075] In this embodiment, to avoid misjudgment that could prevent the door from closing properly, logic can be added to the anti-pinch control method of the latching lock to force the target latching lock to close after two consecutive anti-pinch triggers.

[0076] Specifically, a cumulative count variable can be set, with an initial value of 0. During the closing process of the target latching lock, the cumulative count variable is incremented by 1 each time the anti-pinch function is triggered. When the value of the variable is greater than or equal to 2, the target latching lock is controlled to complete the closing action and reach the fully closed state.

[0077] The anti-pinch control method for a suction lock provided in this invention first acquires the switch signal and motor Hall signal of the target suction lock, and determines the current suction position of the target suction lock based on the switch signal and motor Hall signal; then, it determines the energy increment of the target suction lock from the start of suction to reaching the current suction position, and determines the energy threshold corresponding to the current suction position; if the energy increment is greater than the energy threshold corresponding to the current suction position, the suction action of the target suction lock is stopped. This invention discloses an anti-pinch control method for suction locks that calculates the energy increment during the suction process, uses the magnitude of the energy increment as the anti-pinch trigger condition, and determines the corresponding energy threshold based on the real-time suction position of the suction lock. This allows for accurate anti-pinch judgment, solving the problem of hand pinching risk during the use of suction locks, and also uses the capacitive signal inside the door handle to judge human actions, achieving rapid response to user actions.

[0078] Example 2

[0079] Figure 2 This is a flowchart of a suction lock anti-pinch control method provided in Embodiment 2 of the present invention. This embodiment is a refinement of the above embodiment, such as... Figure 2 As shown, the method includes:

[0080] S210. Collect the switch signal of the target latching lock and the Hall signal of the motor, and determine the latching state of the target latching lock based on the switch signal.

[0081] The engagement state includes fully open, fully closed, and engaged. The switching signals can include the pawl signal, ratchet signal, and door open signal of the target engagement lock.

[0082] In this embodiment, the control device for the target latching lock can acquire the pawl signal, ratchet signal, and door opening signal of the target latching lock in real time through a signal acquisition module, and acquire the Hall signal of the target latching lock's motor in real time through a Hall acquisition module. When the target latching lock is in different latching states, the corresponding acquisition of switch signals is different. Based on the acquired switch signals, the current latching state of the target latching lock can be determined.

[0083] Preferably, the switching signals include a latching pawl signal, a ratchet signal, and a door opening signal. When the target latching lock is in the fully open state, the pawl signal, ratchet signal, and door opening signal are all triggered. When the target latching lock is in the fully closed state, the pawl signal and ratchet signal are triggered.

[0084] Furthermore, before acquiring the switch signal and motor Hall signal of the target latching lock, it is also possible to: obtain at least two latching intervals by dividing the overall latching process of the target latching lock from fully open to fully closed.

[0085] In this embodiment, the engagement interval can be pre-calibrated based on the switch signal of the target engagement lock and the Hall signal of the motor. Specifically, during calibration, when the target engagement lock is determined to be in the fully closed state based on the switch signal, one Hall signal value is recorded; when the target engagement lock is determined to be in the fully open state based on the switch signal, another Hall signal value is recorded. The signal value interval between these two signal values ​​represents the Hall signal change during the entire engagement process of the target engagement lock from fully open to fully closed. By dividing this signal value interval, the engagement interval of the target engagement lock can be obtained.

[0086] Optionally, the number of engagement intervals can be set according to requirements. For example, the entire engagement process of the target engagement lock from fully open to fully closed can be divided into five segments, resulting in five engagement intervals.

[0087] S220. Determine the first Hall signal value and the second Hall signal value of the target locking lock in the fully open and fully closed states respectively. If the target locking lock is in the locking state, determine the current locking position of the target locking lock based on the motor Hall signal, the first Hall signal value and the second Hall signal value.

[0088] In this embodiment, the Hall signal of the motor of the target locking lock is collected in real time by the Hall acquisition module. According to the pre-divided locking interval of the target locking lock, the first Hall signal value and the second Hall signal value of the target locking lock in the fully open and fully closed states can be determined. In the locking state of the target locking lock, the current locking position of the target locking lock can be determined according to the motor Hall signal, the first Hall signal value and the second Hall signal value.

[0089] Optionally, the absolute value of the difference between the first Hall signal value and the second Hall signal value can be calculated, and the ratio of the acquired motor Hall signal to this absolute value can be calculated. This ratio can then be used to characterize the current engagement position of the target locking mechanism.

[0090] S230: Collect the motor current signal of the target latch from the start of latching to the current latching position, and determine the energy increment based on the motor current signal.

[0091] Among them, the motor current signal is the current signal of the motor that drives the target locking mechanism.

[0092] In this embodiment, the control device of the target latch can collect the motor current signal of the target latch in real time through the current acquisition module, and calculate the energy increment in real time based on the collected motor current signal.

[0093] Optionally, the energy increment can be obtained by integrating the motor current signal.

[0094] S240. Obtain at least two engagement intervals by dividing the overall engagement process of the target engagement lock from fully open to fully closed, determine the target engagement interval to which the current engagement position belongs in the at least two engagement intervals, and determine the energy threshold corresponding to the target engagement interval as the energy threshold corresponding to the current engagement position.

[0095] Among them, each of the at least two attraction intervals corresponds to an energy threshold.

[0096] In this embodiment, after determining the current engagement position of the target latching lock, the engagement interval to which the current engagement position belongs can be used as the target engagement interval based on the pre-defined engagement intervals. Preferably, when dividing the engagement intervals of the target latching lock, an energy threshold can be set for each interval, with different energy thresholds corresponding to different engagement intervals. Therefore, after determining the target engagement interval corresponding to the current engagement position, the energy threshold corresponding to the target engagement interval can be obtained and set as the energy threshold corresponding to the current engagement position. Thus, the anti-pinch determination of the target latching lock is performed based on the relationship between the energy increment during the process of the target latching lock from the start of engagement to reaching the current engagement position and the corresponding energy threshold.

[0097] S250. If the energy increment is greater than the energy threshold corresponding to the current engagement position, then stop the engagement action of the target engagement lock.

[0098] In this embodiment, if the energy increment is greater than the energy threshold corresponding to the current engagement position, it can be determined that a pinching situation may occur. When this situation occurs, anti-pinch processing can be triggered, and the control device of the target engagement lock can send a control signal to the motor of the target engagement lock to stop the engagement action of the target engagement lock.

[0099] Furthermore, if a capacitor switching signal is detected inside the door handle, the closing action of the target latching lock will be stopped.

[0100] In this embodiment, the capacitor switching signal inside the door handle is the capacitor switching signal collected from the door handle of the vehicle door on which the target magnetic lock is installed. When the capacitor switching signal inside the door handle is collected, it can be determined that there may be a situation where the door handle is being pulled. Therefore, if the energy increment is greater than the energy threshold corresponding to the current magnetic position, it can be determined that a pinch situation may occur; if the capacitor switching signal inside the door handle is collected, it can be determined that there may be a situation where the door handle is being pulled. When one of the above two situations occurs, the anti-pinch processing can be triggered, and the control device of the target magnetic lock can send a control signal to the motor of the target magnetic lock to stop the magnetic lock's magnetic action.

[0101] Figure 3 This is a schematic diagram of signal acquisition in the anti-pinch control of a suction lock according to Embodiment 2 of the present invention. As shown in the figure, the control device of the target suction lock sends a drive signal to the motor of the target suction lock through the motor drive unit, thereby controlling the target suction lock. The control device acquires the switch signals of the target suction lock through the switch signal acquisition module, including the pawl signal, ratchet signal, and door open signal, and acquires the motor current signal and motor Hall signal of the target suction lock through the current signal acquisition module and the Hall signal acquisition module, respectively. At the same time, the control device also acquires the capacitance signal inside the door handle through the capacitance signal acquisition module.

[0102] The anti-pinch control method for a magnetic lock provided in this invention calculates the energy increment during the magnetic closing process and uses the magnitude of the energy increment as the anti-pinch trigger condition. This allows for accurate anti-pinch determination, solving the risk of hand pinching during the use of magnetic locks. Furthermore, it uses the capacitance signal inside the door handle to detect human action, enabling rapid response to user actions. Further, by collecting the switch signal and motor Hall signal of the magnetic lock to determine its current position, the corresponding energy threshold can be determined based on the real-time magnetic closing position, thereby achieving more precise anti-pinch judgment and improving accuracy.

Figure 4 As shown, the device includes: a current engagement position determination module 310, an energy increment determination module 320, and an anti-pinch control module 330.

[0105] The current engagement position determination module 310 is used to collect the switch signal and motor Hall signal of the target engagement lock, and determine the current engagement position of the target engagement lock based on the switch signal and motor Hall signal.

[0106] The energy increment determination module 320 is used to determine the energy increment of the target latching lock from the start of latching to the current latching position, and to determine the energy threshold corresponding to the current latching position.

[0107] The anti-pinch control module 330 is used to stop the target latching lock's latching action if the energy increment is greater than the energy threshold corresponding to the current latching position.

[0108] Optionally, the current engagement position determination module 310 is also used for:

[0109] The engaging state of the target locking lock is determined based on the switch signal; wherein the engaging state includes fully open, fully closed, and engaging; the first Hall signal value and the second Hall signal value of the target locking lock are determined respectively in the fully open and fully closed states; if the engaging state of the target locking lock is engaging, the current engaging position of the target locking lock is determined based on the motor Hall signal, the first Hall signal value, and the second Hall signal value.
