[0002] With the development of the automobile industry and the improvement of the popularity of automobiles, people have higher and higher requirements for the performance of automobiles. The vehicle box door is a passage for people or goods to enter and exit. When loading and unloading the vehicle box, the vehicle box door needs to be opened and closed after the loading and unloading is completed.

[0003] The traditional vehicle box lock has a simple function and is mostly mechanical and manually operated, which is very laborious. In order to reduce the burden on users, some high-end vehicles use a double-motor scheme to realize the locking and unlocking of the vehicle box door, that is, an unlocking motor is used to realize the unlocking of the vehicle box door, and a locking motor is used to realize the locking of the vehicle box door. However, this scheme uses two independent motors, which leads to problems such as large arrangement volume, poor reliability, high production cost, etc. of the vehicle box lock. At the same time, the two motors need to be controlled respectively, and communication and interaction between multiple modules are needed, which leads to a relatively complex hardware structure and control logic of the vehicle box lock.

[0067] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a 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.

[0068] It should be noted that transport vehicles such as pickup trucks and vans are usually equipped with a vehicle box. For example, some pickup trucks or part of the vans are provided with a half-enclosed vehicle box without a roof behind the cab, and some vans are provided with a fully-enclosed vehicle box with a roof behind the cab. No matter which type of vehicle box, a vehicle box lock is configured to realize the opening and closing of the vehicle box door.

[0069] The current vehicle box lock usually adopts a mechanical lock or an electric lock, which needs to be manually closed by the user, i.e. the user needs to manually lift the vehicle box door to realize unlocking and locking. However, the vehicle box door is usually high from the ground, especially when closing the door, a large torque is required, which makes it difficult for users with small stature or weak strength to close the door. Some high-end vehicle models with electric self-suction and electric unlocking functions of the vehicle box lock mostly adopt a double-motor structure to realize locking and unlocking, i.e. the locking motor is only responsible for self-suction locking, and the unlocking motor is only responsible for electric unlocking. The controller sends action instructions to the corresponding motor to realize locking and unlocking. This structure adopts two independent motors, which leads to the problems of large arrangement volume, poor reliability, and high production cost of the vehicle box lock. At the same time, the two motors need to be controlled respectively, and communication and interaction between multiple modules are required, which leads to the complexity of the mechanical structure and control logic of the vehicle box lock, and poor reliability.

[0070] In view of the problems of large arrangement volume of the current vehicle box lock and the complexity of the hardware structure and control logic of the vehicle box lock, the present application aims to provide a vehicle box self-suction lock control method. By setting a self-suction lock on the vehicle box door and controlling the single motor of the self-suction lock to reverse, automatic unlocking and automatic locking of the vehicle box door can be realized. This not only can effectively reduce the arrangement volume of the vehicle box lock and reduce the production cost, but also can reduce the complexity of the structure and control logic of the self-suction lock, thereby improving the reliability of the self-suction lock.

[0071] Reference Figure 1 , a vehicle box self-suction lock control method is shown. The method can include the following steps:

[0072] S101: In response to the door lock control instruction triggered by the user for the trunk door, determine the target rotation direction of the drive motor.

[0073] It should be noted that the execution subject of the present embodiment can be a self-suction lock controller, or an electronic device with data processing, network communication and program running functions in the vehicle, such as an ECU (Electronic Control Unit), a BCM (Body Control Module), a VCU (Vehicle Control Unit), etc.

[0074] Specifically, when the execution subject is a self-suction lock controller, the self-suction lock controller can be connected with the position sensor to obtain the position information of the trunk door collected by the position sensor, and then control the drive motor of the self-suction lock based on the position information; when the execution subject is an ECU, the ECU can be connected with the position sensor and the self-suction lock controller respectively, and then the ECU can control the self-suction lock by obtaining the position information of the trunk door collected by the position sensor and sending corresponding control instructions to the self-suction lock controller.

[0075] Preferably, in order to reduce the additional wiring cost and facilitate the linkage control of the trunk door, the present embodiment will take the ECU as the execution subject for illustration. For example, when the trunk door is also provided with a control device such as an electric hinge, the self-suction lock controller and the electric hinge can be controlled to cooperate to achieve the opening and closing of the trunk door. It should be noted that the ECU is composed of a microcontroller (MCU), a memory (ROM, RAM), an input / output interface (I / O), an analog-to-digital converter (A / D), and a large-scale integrated circuit for shaping and driving. The ECU has the functions of operation and control. It collects signals from various sensors, performs operations, and converts the results of the operations into control signals to control the work of multiple controlled objects.

[0076] It should be noted that the trunk includes a trunk body fixedly connected to the vehicle and a trunk door rotatably connected to the trunk body, the self-suction lock is arranged on the trunk door and rotates with the trunk door, the trunk body is provided with a lock catch mechanism, the self-suction lock includes a locking mechanism and a single drive motor that can rotate in both directions, and the self-suction lock can be connected to the lock catch mechanism in half-lock or full-lock through the locking mechanism. Specifically, the locking mechanism includes a half-lock mechanism and a full-lock mechanism, and the self-suction lock can be connected to the lock catch mechanism in half-lock through the half-lock mechanism, or connected to the lock catch mechanism in full-lock through the full-lock mechanism. Specifically, the trunk door can be a trunk back panel or a trunk side panel.

[0077] In the embodiment, the door lock control instruction specifically includes an opening control instruction and a closing control instruction, and different door lock control instructions correspond to different rotation directions. Specifically, the target rotation direction corresponding to the opening control instruction can be defined as the clockwise direction, and the target rotation direction corresponding to the closing control instruction can be defined as the counterclockwise direction. It should be noted that the correspondence between the door lock control instruction and the rotation direction can be self-defined according to the installation needs of the mechanical structure, and the embodiment is not specifically limited.

[0078] In a specific implementation, the user can trigger the door lock control instruction in multiple ways. For example, the user can trigger a preset door lock button on the smart key, or trigger a preset physical button on the vehicle door, or trigger a preset virtual button on the central control display screen, or directly issue a voice instruction to send the door lock control instruction to the ECU. The ECU determines the target rotation direction of the drive motor in response to the door lock control instruction triggered by the user for the vehicle door, and controls the drive motor of the self-suction lock to operate in the target rotation direction.

[0079] S102: In the process of controlling the drive motor to operate in the target rotation direction, the half-lock signal and the full-lock signal of the self-suction lock are monitored in real time.

[0080] In the embodiment, the ECU monitors the half-lock signal and the full-lock signal of the self-suction lock in real time by collecting the position information of the vehicle door through the position sensor during the operation of the drive motor. That is, when the ECU obtains the half-lock signal sent by the position sensor, it indicates that the vehicle door is in the half-lock position, and at this time the self-suction lock is in the half-lock connection state through the locking mechanism and the lock catch mechanism. When the ECU obtains the full-lock signal sent by the position sensor, it indicates that the vehicle door is in the full-lock position, and at this time the self-suction lock is in the full-lock connection state through the locking mechanism and the lock catch mechanism.

[0081] Preferably, to further reduce the arrangement volume of the vehicle lock, the position sensor can adopt a Hall sensor. Compared with a conventional micro switch, the Hall sensor has the advantages of firm structure, small size, light weight, convenient installation, small power consumption, high frequency, resistance to vibration, and resistance to pollution or corrosion of dust, oil stains, water vapor, and salt mist. The Hall sensor can detect the magnetic field change around the self-suction lock in real time, and generate corresponding voltage information to detect whether the vehicle door is pulled, and the Hall sensor can also detect the position and angle of the vehicle door to ensure that the vehicle door is closed at the correct position.

[0082] In a specific implementation, the ECU acquires the voltage information collected by the Hall sensor in real time during the process of controlling the self-inhaling lock to operate in the target rotation direction; and then determines whether the self-inhaling lock triggers the half-lock signal or the full-lock signal based on the voltage information. Specifically, when it is detected that the voltage information is located in the first voltage range, it is determined that the self-inhaling lock triggers the half-lock signal, at which time the vehicle compartment door enters the half-lock position; when it is detected that the voltage information is located in the second voltage range, it is determined that the self-inhaling lock triggers the full-lock signal, at which time the vehicle compartment door enters the full-lock position.

[0083] In the present embodiment, in order to achieve accurate monitoring of the half-lock signal and the full-lock signal and avoid false triggering, it can be provided that when the first duration of the voltage information being located in the first voltage range is greater than a first time threshold, it is determined that the self-inhaling lock triggers the half-lock signal; and it can also be provided that when the second duration of the voltage information being located in the second voltage range is greater than a second time threshold, it is determined that the self-inhaling lock triggers the full-lock signal. The first time threshold can be set to 100 ms, and the second time threshold can be set to 350 ms.

[0084] S103: Determine whether the driving motor meets a preset motor reset condition based on the door lock control instruction, the half-lock signal and the full-lock signal.

[0085] In the present embodiment, since the half-lock signal and the full-lock signal can respectively reflect the position information of the vehicle compartment door, and different door lock control instructions stipulate different timing change characteristics of the half-lock signal and the full-lock signal under normal circumstances, the ECU can effectively determine whether the vehicle compartment door is unlocked or locked based on the door lock control instruction, the half-lock signal and the full-lock signal.

[0086] Specifically, the motor reset condition includes an opening reset condition corresponding to the opening control instruction and a closing reset condition corresponding to the closing control instruction. The opening reset condition represents that the self-inhaling lock has completed the unlocking operation, and the closing reset condition represents that the self-inhaling lock has completed the locking operation.

[0087] In a specific implementation, in the case where the door lock control instruction is the opening control instruction, if the ECU detects that the full-lock signal and the half-lock signal disappear in sequence, it is determined that the driving motor meets the opening reset condition, at which time the self-inhaling lock has completed the unlocking operation; in the case where the door lock control instruction is the closing control instruction, if the ECU detects that the half-lock signal and the full-lock signal trigger in sequence, it is determined that the driving motor meets the closing reset condition, at which time the self-inhaling lock has completed the locking operation.

[0088] S104: In the case where the driving motor meets the motor reset condition, it is determined that the self-inhaling lock completes the operation corresponding to the door lock control instruction, and the driving motor is controlled to reverse and reset.

[0089] In the embodiment, the ECU considers that the self-sucking lock has completed the locking operation or the self-sucking lock has completed the locking operation after detecting that the driving motor meets the motor resetting condition, and then controls the driving motor to reverse to reset the driving motor. It should be noted that if the user triggers the door lock control instruction again, the ECU controls the driving motor to perform the operation opposite to the last time to achieve the unlocking and locking of the vehicle door, for example, the last door lock control instruction is the opening control instruction, and the door lock control instruction triggered again is the closing control instruction. In this way, the unlocking and locking of the vehicle door can be controlled by a single control button.

[0090] The embodiment of the application can realize the automatic unlocking and locking of the vehicle door by controlling the single motor of the self-sucking lock to reverse, can effectively reduce the arrangement volume of the vehicle lock, reduce the production cost, and reduce the complexity of the structure and control logic of the self-sucking lock, thereby improving the reliability of the self-sucking lock.

[0091] In a feasible embodiment, the vehicle self-sucking lock control method can further include the following steps:

[0092] S201: In the case of a closing control instruction, if the half-lock signal is received, the self-sucking time of the driving motor is counted.

[0093] In the embodiment, considering that there may be obstacles such as clothes and goods in the process of closing the vehicle door, which hinder the normal closing of the vehicle door, in order to detect the closing abnormality in the locking process of the self-sucking lock, the ECU will trigger the counting of the self-sucking time of the driving motor after receiving the half-lock signal, and then judge whether the self-sucking lock is normally closed within the specified time based on the self-sucking time.

[0094] S202: In the case that the self-sucking time reaches the first preset time length and the full-lock signal is not detected, output a closing abnormality prompt information, control the driving motor to stop, and perform a resetting operation.

[0095] It should be noted that the first preset time length represents the longest time for the self-sucking lock to be successfully closed, for example, it can be set to 1.5s. That is, the ECU will output a closing abnormality prompt information to prompt the user that the vehicle door cannot be normally closed, please check after detecting that the self-sucking time reaches 1.5s; at the same time, in order to avoid the driving motor from generating a long-time blocking current when the vehicle door is stuck, causing damage to the driving motor, the driving motor is stopped and a resetting operation is performed.

[0096] In a feasible implementation, the vehicle compartment is further provided with an electric hinge, and the vehicle compartment self-latch control method can further include the following steps:

[0097] S301: In the case of receiving the opening control instruction, triggering the timing of the unlocking time of the drive motor.

[0098] In this embodiment, in order to enable the vehicle compartment door to be smoothly unlocked within a short time, after receiving the opening control instruction, the ECU will immediately start timing the unlocking time of the drive motor while sending the opening control instruction to the self-latch controller, and then determine whether the self-latch is smoothly unlocked within the specified time based on the unlocking time.

[0099] S302: In the case where the unlocking time reaches the second preset duration and the half-lock signal is not detected to disappear, control the electric hinge to drive the vehicle compartment door to open to assist the drive motor to perform the unlocking operation.

[0100] In this embodiment, the second preset duration represents the longest time that the self-latch can be unlocked by itself, which can be set to 1s. That is, after detecting that the unlocking time reaches 1s, the ECU determines that the self-latch cannot be smoothly unlocked because the half-lock signal has not disappeared, at which time the ECU will control the electric hinge to drive the vehicle compartment door to open to assist the drive motor to perform the unlocking operation.

[0101] In a specific implementation, the ECU is also connected with a hinge controller of the electric hinge, and the vehicle compartment door opening instruction is sent to the hinge controller to control the electric hinge to drive the vehicle compartment door to open in response to the vehicle compartment door opening instruction. It should be noted that one end of the electric hinge is fixedly connected with the vehicle compartment door, and the other end of the electric hinge is fixedly connected with the vehicle compartment body, and then the electric hinge can pull the vehicle compartment door up or down with the vehicle compartment body as the fulcrum to assist the self-latch to perform the unlocking operation or the locking operation.

[0102] In this embodiment, by intervening the unlocking operation of the drive motor through the electric hinge, the drive motor can be assisted to smoothly complete the unlocking operation when the torque output by the drive motor is insufficient.

[0103] In this embodiment, the number of interventions of the electric hinge assisting the self-latch to perform the unlocking operation can also be recorded, and then in the case where it is detected that the number of interventions is greater than a number threshold, an unlocking abnormality prompt information is outputted, which is used to prompt the user that the self-latch has an unlocking abnormality for the user to check and handle.

[0104] In a feasible implementation, in order to realize the cooperation of the electric hinge and the self-latch, the vehicle compartment self-latch control method can further include the following steps:

[0105] S401: If the door lock control instruction is an opening control instruction, and if the half-lock signal disappears, the electric hinge is controlled to drive the vehicle door to open to a fully open position.

[0106] It should be noted that the entire opening process of the vehicle door can be divided into an unlocking phase and a fully open phase, wherein the unlocking phase is completed by the self-locking, and the fully open phase is completed by the electric hinge. Specifically, the unlocking phase includes a fully locked phase and a half-locked phase. When the self-locking performs the unlocking operation, the vehicle door enters the half-locked state from the fully locked state. When the half-locked signal disappears, the vehicle lock exits the half-locked state and enters the fully open phase.

[0107] In the present embodiment, in order to realize smooth operation of the vehicle door in the fully open phase, the ECU controls the electric hinge to drive the vehicle door to open to a fully open position, so as to avoid the vehicle door from rapidly falling under the action of gravity and hitting the vehicle body, thereby causing impact on the vehicle.

[0108] It should be noted that if it is detected that the self-locking cannot be successfully unlocked in the unlocking phase, the electric hinge can be controlled to intervene to assist the self-locking to perform the unlocking operation. For details, refer to the specific embodiments of steps S301-S302, which will not be described here.

[0109] S402: If the door lock control instruction is a closing control instruction, the electric hinge is controlled to drive the vehicle door to close until the half-lock signal is received, and the self-locking is controlled to perform a locking operation.

[0110] It should be noted that the entire closing process of the vehicle door can be divided into a first locking phase and a second locking phase, wherein the first locking phase is completed by the electric hinge, and the second locking phase is completed by the self-locking. Specifically, in the first locking phase, the electric hinge drives the vehicle door to close from the fully open position to the fully locked position until the half-lock signal is received, the first locking phase is completed and enters the second locking phase, and in the second locking phase, the ECU controls the self-locking to perform a locking operation, so as to further close the vehicle door to the fully locked position.

[0111] It should be noted that in the second locking phase, the steps S201-S202 will be performed to avoid the driving motor from running for a long time when the vehicle door cannot be normally closed.

[0112] In one possible embodiment, the vehicle door is a vehicle rear panel, and the vehicle rear panel is provided with two self-lockings. The vehicle self-locking control method can further include the following steps:

[0113] S501: If the door lock control instruction is a closing control instruction, and if only the half-lock signal of one of the two self-lockings is received, the electric hinge is controlled to drive the vehicle rear panel to close.

[0114] In the embodiment, in order to ensure the firmness of the truck tailgate when it is closed, two self-sucking locks are arranged on both sides of the truck tailgate, and a lock catch mechanism corresponding to each self-sucking lock is arranged on the two side plates of the truck, so that the lock catch mechanisms on both sides jointly lock the truck tailgate, ensuring the safe use of the truck tailgate.

[0115] In the embodiment, if the ECU receives the half-lock signals of the two self-sucking locks within a preset time interval during the process of controlling the truck tailgate to be closed, it is considered that the truck tailgate has reached the half-lock position smoothly, and then the ECU controls the two self-sucking locks to perform the locking operation.

[0116] In the embodiment, if the ECU receives only one half-lock signal of the self-sucking lock within a preset time interval during the process of controlling the truck tailgate to be closed, in order to avoid the excessive load of the driving motor caused by the locking operation of the single self-sucking lock, the ECU controls the electric hinge to drive for a third preset time to assist the driving motor to perform the locking operation. The third preset time can be set to 500 ms.

[0117] S502: When the driving time of the electric hinge reaches the third preset time, the driving motors corresponding to the two self-sucking locks are controlled to operate in the target rotation direction to perform the locking operation.

[0118] In the embodiment, after the driving time of the electric hinge to drive the truck tailgate to be closed reaches 500 ms, the ECU controls the two self-sucking locks to perform the locking operation regardless of whether the half-lock of the other self-sucking lock is detected, that is, the driving motors of the two self-sucking locks are controlled to operate in the corresponding target rotation direction until the half-lock signal and the full-lock signal of the two self-sucking locks are triggered, and then the driving motors of the two self-sucking locks are controlled to reset.

[0119] In the embodiment, by controlling the electric hinge to assist the closing when only one half-lock signal of the self-sucking lock is received, on the one hand, the electric hinge can assist the truck tailgate to be closed smoothly when the self-sucking torque of the self-sucking lock is insufficient, and on the other hand, the self-sucking operation of the two self-sucking locks can be synchronized to improve the self-sucking effect and avoid the excessive load of the driving motor caused by the locking operation of the single self-sucking lock.

[0120] In a feasible embodiment, in order to ensure that the self-sucking lock can operate normally when it is powered on again after power failure, the truck self-sucking lock control method can further include the following steps:

[0121] S601: In the case that the self-sucking lock is powered on again after power failure, the half-lock signal and the full-lock signal of the self-sucking lock are acquired.

[0122] In the embodiment, the ECU will detect the half-lock signal and the full-lock signal of the self-locking lock after the self-locking lock is re-powered, and then determine whether the self-locking lock is abnormally powered off during the unlocking or locking process. Specifically, the current state of the vehicle door can be determined based on the signal truth table shown in Table 1.

[0123] Table 1 Signal truth table

[0124]

[0125] It should be noted that "1" indicates the presence of the corresponding signal, and "0" indicates the absence of the corresponding signal. Specifically, when both the half-lock signal and the full-lock signal are detected, it indicates that the vehicle door is in a full-lock state, and at this time the drive motor of the self-locking lock may have been reset or may not have been completely reset; when only the half-lock signal is detected, it indicates that the vehicle door is in a half-lock state, and at this time the self-locking lock may be powered off during the locking process or powered off during the unlocking process; when both the half-lock signal and the full-lock signal are not detected, it indicates that the vehicle door is in a fully open state.

[0126] In the embodiment, considering that the power-off when the vehicle door is in a fully open state has no effect on the self-locking lock, when both the half-lock signal and the full-lock signal are not detected, it is considered normal and no operation is required for the self-locking lock, and if the second door lock control instruction triggered by the user through the preset button is received again, the locking operation is normally performed.

[0127] S602: In the case where the half-lock signal and / or the full-lock signal is detected, the self-locking lock is kept from operating until the second door lock control instruction triggered by the user for the vehicle door is received, and the self-locking lock is controlled to perform the unlocking operation.

[0128] In the embodiment, considering that the power-off when the vehicle door is in a half-lock state or a full-lock state will affect the self-locking lock, i.e., the self-locking lock is abnormally powered off during operation. Specifically, if the vehicle door is in a half-lock state, it indicates that the pawl in the locking mechanism of the self-locking lock has not completely disengaged from the ratchet, and the ratchet is still in a half-lock state; if the vehicle door is in a full-lock state, it may jam the pawl, making the ratchet unable to normally reset. Therefore, when both the half-lock signal and / or the full-lock signal are detected, to avoid the self-locking lock running in the wrong direction and failing to smoothly lock, the self-locking lock controller will not control the self-locking lock to make any operation after being re-powered, so that the vehicle door remains in a half-lock or full-lock state, until the self-locking lock controller receives the second door lock control instruction triggered by the user again, and then determines that the second door lock control instruction is an unlocking instruction, and controls the self-locking lock to perform the unlocking operation to open the vehicle door to a fully open position.

[0129] In the embodiment, by detecting the half-lock signal and the full-lock signal of the self-sucking lock after the self-sucking lock is powered on again, the self-sucking lock can be ensured to normally operate after being powered on again in the case of abnormal power-off, and abnormal operation of the self-sucking lock is avoided.
