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

[0003] Traditional trunk locks have simple functions, are mostly mechanical and manual, and are very laborious. In order to reduce the burden on users, some high-end models use a dual-motor solution to lock and unlock the trunk door, that is, an unlocking motor is used to unlock the trunk door, and a locking motor is used to lock the trunk door. However, due to the use of two independent motors, this method causes the trunk lock to have problems such as large layout volume, poor reliability, and high production cost; at the same time, the two motors need to be controlled separately, and multiple modules need to communicate and interact, resulting in a relatively complex hardware structure and control logic of the trunk lock.

[0067] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 the present invention.

[0068] It should be noted that transport vehicles such as pickup trucks and trucks are usually equipped with a box. For example, a pickup truck or some trucks are equipped with a semi-enclosed box without a roof behind the cab, and some trucks are equipped with a fully enclosed box with a roof behind the cab. Regardless of the type of box, a box lock is configured to open and close the box door.

[0069] At present, trunk locks usually use mechanical locks or electric unlocking, which require users to close manually, that is, users need to lift the trunk door manually to unlock and lock it. The trunk door is usually high from the ground, especially when closing the door, a large torque is required, which makes it difficult for users with short stature or weak strength to close the door. Most high-end models of trunk locks with electric self-priming and electric unlocking functions use a dual-motor structure to achieve locking and unlocking respectively, that is, the locking motor is only responsible for self-priming locking, and the unlocking motor is only responsible for electric unlocking. The controller sends action commands to the corresponding motors to achieve locking and unlocking. This structure uses two independent motors, resulting in large layout volume, poor reliability, high production cost and other problems of the trunk lock. At the same time, the two motors need to be controlled separately, and multiple modules need to communicate and interact, resulting in the trunk lock being more complex in both mechanical structure and control logic, and poor reliability.

[0070] In response to the current problems of large layout volume of carriage locks and relatively complex hardware structure and control logic of carriage locks, the present application aims to provide a method for controlling a carriage self-priming lock. By setting a self-priming lock on the carriage door and controlling the single motor of the self-priming lock to rotate forward and reverse, automatic unlocking and automatic locking of the carriage door can be achieved. This can not only effectively reduce the layout volume of the carriage lock and reduce production costs, but also reduce the complexity of the structure and control logic of the self-priming lock, thereby improving the reliability of the self-priming lock.

[0071] Reference Figure 1 , shows a vehicle box self-priming lock control method of the present application, the method may include the following steps:

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

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

[0074] Specifically, when the executing entity is a self-priming lock controller, the self-priming lock controller can be connected to a position sensor to obtain the position information of the vehicle door collected by the position sensor, and then control the driving motor of the self-priming lock based on the position information; when the executing entity is an ECU, the ECU can be connected to the position sensor and the self-priming lock controller respectively, and then the ECU can obtain the position information of the vehicle door collected by the position sensor, and send corresponding control instructions to the self-priming lock controller to achieve control of the self-priming lock.

[0075] Preferably, in order to reduce the additional wiring cost and facilitate the linkage control of the car door, this embodiment will be described with ECU as the execution subject. For example, when the car door is also provided with a control device such as an electric hinge, the self-priming lock controller and the electric hinge can be controlled to cooperate to realize the opening and closing of the car 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 large-scale integrated circuits such as shaping and driving. The ECU has the functions of calculation and control. It collects signals from various sensors, performs calculations, and converts the results of the calculations into control signals to control the work of multiple controlled objects.

[0076] It should be noted that the vehicle box includes a vehicle box body fixedly connected to the vehicle and a vehicle box door rotatably connected to the vehicle box body. The self-priming lock is arranged on the vehicle box door and rotates with the rotation of the vehicle box door. The vehicle box body is provided with a locking mechanism. The self-priming lock includes a locking mechanism and a single driving motor that can rotate forward and reversely. The self-priming lock can be semi-locked or fully locked with the locking mechanism through the locking mechanism. Specifically, the locking mechanism includes a semi-locking mechanism and a full-locking mechanism. The self-priming lock can be semi-locked with the locking mechanism through the semi-locking mechanism, or can be fully locked with the locking mechanism through the full-locking mechanism. Specifically, the vehicle box door can be a rear fender or a side panel of the vehicle box.

[0077] In this 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 specified as a clockwise direction, and the target rotation direction corresponding to the closing control instruction can be specified as a counterclockwise direction. It should be noted that the correspondence between the door lock control instruction and the rotation direction can be customized according to the installation requirements of the mechanical structure, and this embodiment does not specifically limit it.

[0078] In a specific implementation, the user can trigger the door lock control command in a variety of ways. For example, the user can trigger the preset door lock button on the smart key, or the preset physical button pre-set on the car door, or the preset virtual button on the central control display, or directly issue a voice command to send the door lock control command to the ECU. The ECU responds to the door lock control command triggered by the user for the car door, determines the target rotation direction of the drive motor, and controls the drive motor of the self-priming lock to run in the target rotation direction.

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

[0080] In this embodiment, the ECU uses the position information of the vehicle door collected by the position sensor to monitor the half-lock signal and the full-lock signal of the self-priming lock in real time during the operation of the drive motor. That is, when the ECU obtains the half-lock signal sent by the position sensor, it means that the vehicle door is in a half-locked position, and the self-priming lock is in a half-locked connection state through the locking mechanism and the lock mechanism; when the ECU obtains the full-lock signal sent by the position sensor, it means that the vehicle door is in a full-locked position, and the self-priming lock is in a full-locked connection state through the locking mechanism and the lock mechanism.

[0081] Preferably, in order to further reduce the layout volume of the trunk lock, the position sensor can be a Hall sensor. Compared with conventional micro switches, Hall sensors have the advantages of firm structure, small size, light weight, easy installation, low power consumption, high frequency, vibration resistance, and no fear of pollution or corrosion from dust, oil, water vapor and salt spray. The Hall sensor will detect the changes in the magnetic field around the self-priming lock in real time, and then generate corresponding voltage information to detect whether the trunk door is pulled. At the same time, the Hall sensor can also detect the position and angle of the trunk door to ensure that the trunk door is closed in the correct position.

[0082] In the specific implementation, the ECU will obtain the voltage information collected by the Hall sensor in real time while controlling the self-priming lock to run in the target rotation direction; then, based on the voltage information, it will determine whether the self-priming lock triggers a half-lock signal or a full-lock signal. Specifically, when it is detected that the voltage information is in the first voltage range, it is determined that the self-priming lock triggers a half-lock signal, and the door enters the half-lock position; when it is detected that the voltage information is in the second voltage range, it is determined that the self-priming lock triggers a full-lock signal, and the door enters the full-lock position.

[0083] In this embodiment, in order to accurately monitor the half-lock signal and the full-lock signal and avoid false triggering, it can be set that when the first duration of the voltage information in the first voltage range is greater than the first duration threshold, it is determined that the self-priming lock triggers the half-lock signal trigger; at the same time, it can also be set that when the second duration of the voltage information in the second voltage range is greater than the second duration threshold, it is determined that the self-priming lock triggers the full lock signal. Among them, the first duration threshold can be set to 100ms, and the second duration threshold can be set to 350ms.

[0084] S103: Based on the door lock control instruction, the half lock signal and the full lock signal, determine whether the drive motor meets a preset motor reset condition.

[0085] In this embodiment, since the half-lock signal and the full-lock signal can respectively reflect the position information of the vehicle door, and different door lock control instructions specify 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 door is unlocked or locked based on the door lock control instructions, half-lock signal and 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 indicates that the self-priming lock has completed the unlocking operation; the closing reset condition indicates that the self-priming lock has completed the locking operation.

[0087] In the specific implementation, when 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 determines that the drive motor meets the opening reset condition, and the self-priming lock has completed the unlocking operation; when the door lock control instruction is the closing control instruction, if the ECU detects that the half lock signal and the full lock signal are triggered in sequence, it determines that the drive motor meets the closing reset condition, and the self-priming lock has completed the locking operation.

[0088] S104: When the driving motor meets the motor reset condition, determine that the self-priming lock completes the operation corresponding to the door lock control instruction, and control the driving motor to reverse and reset.

[0089] In this embodiment, after the ECU detects that the drive motor meets the motor reset condition, it considers that the self-priming lock has completed the locking operation or the self-priming lock has completed the locking operation, and then controls the drive motor to reverse to reset the drive motor. It should be noted that if the door lock control command triggered by the user is obtained again, the ECU will control the drive motor to perform the opposite operation to the last time to achieve the unlocking and locking of the vehicle door. For example, when the last door lock control command is an opening control command, the door lock control command triggered again is a closing control command. In this way, the unlocking and locking of the vehicle door can be controlled by a single control button.

[0090] The embodiment of the present application arranges a self-priming lock on the vehicle door, and adopts a Hall sensor instead of a microswitch to monitor the half-lock signal and the full-lock signal of the self-priming lock. It can realize automatic unlocking and automatic locking of the vehicle door by controlling the forward and reverse rotation of the single motor of the self-priming lock. This can not only effectively reduce the layout volume of the vehicle lock and reduce the production cost, but also reduce the complexity of the structure and control logic of the self-priming lock, thereby improving the reliability of the self-priming lock.

[0091] In a feasible implementation manner, the vehicle box self-priming lock control method may further include the following steps:

[0092] S201: When the door lock control command is a closing control command, if a half-lock signal is received, the timing of the self-priming time of the drive motor is triggered.

[0093] In this embodiment, taking into account that during the closing process of the vehicle door, there may be obstacles such as clothes and cargo that hinder the normal closing of the vehicle door. Therefore, in order to detect the abnormal closing phenomenon during the locking process of the self-priming lock, the ECU will trigger the timing of the self-priming time of the drive motor after receiving the half-lock signal, and then based on the self-priming time, determine whether the self-priming lock is closed normally within the specified time.

[0094] S202: When the self-priming time reaches a first preset time and no full-lock signal is detected, a shutdown abnormality prompt message is output, the drive motor is controlled to stop, and a reset operation is performed.

[0095] It should be noted that the first preset time indicates the longest time that the self-priming lock can be closed smoothly, for example, it can be set to 1.5s. That is to say, after the ECU detects that the self-priming time has reached 1.5s, it will output a closing abnormality prompt message to remind the user that the car door cannot be closed normally, please check; at the same time, in order to avoid the drive motor generating a stall current for a long time when the car door is stuck, causing damage to the drive motor, the drive motor will be stopped and reset.

[0096] In a feasible implementation manner, the vehicle box is further provided with an electric hinge, and the vehicle box self-priming lock control method may further include the following steps:

[0097] S301: When receiving an opening control instruction, triggering the timing of the unlocking time of the driving motor.

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

[0099] S302: When the unlocking time reaches a second preset time and the disappearance of the half-locking signal is not detected, the electric hinge is controlled to drive the vehicle door to open, so as to assist the driving motor in the unlocking operation.

[0100] In this embodiment, the second preset time indicates the longest time that the self-priming lock can unlock itself, and can be set to 1 second, for example. That is to say, after the ECU detects that the unlocking time has reached 1 second and the half-lock signal has not disappeared, it is determined that the self-priming lock cannot be unlocked smoothly. At this time, the ECU will control the electric hinge to drive the car door to open, so as to assist the drive motor to perform the unlocking operation.

[0101] In a specific implementation, the ECU is also connected to the hinge controller of the electric hinge, and sends a door opening instruction to the hinge controller, so that the hinge controller responds to the door opening instruction and controls the electric hinge to drive the door to open. It should be noted that one end of the electric hinge is fixedly connected to the door, and the other end of the electric hinge is fixedly connected to the body of the vehicle, so that the electric hinge can use the body of the vehicle as a force to pull the door up or down to assist the self-priming lock to perform unlocking or locking operations.

[0102] In this embodiment, the electric hinge intervenes in the unlocking operation of the drive motor, so that when the torque output by the drive motor is insufficient, the drive motor can be assisted to successfully complete the unlocking operation.

[0103] In this embodiment, the number of interventions in the unlocking operation of the electric hinge-assisted self-priming lock can also be recorded, and then when it is detected that the number of interventions is greater than the number threshold, an unlocking abnormality prompt message is output. The unlocking abnormality prompt message is used to prompt the user that there is an unlocking abnormality in the self-priming lock, so that the user can check and handle it.

[0104] In a feasible implementation manner, in order to achieve the coordination between the electric hinge and the self-priming lock, the vehicle box self-priming lock control method may further include the following steps:

[0105] S401: When the door lock control command is an opening control command, if it is detected that the half-lock signal disappears, the electric hinge is controlled to drive the vehicle door to open to the fully open position.

[0106] It should be noted that the entire opening process of the trunk door can be divided into the unlocking stage and the full opening stage, wherein the unlocking stage is completed by the self-priming lock, and the full opening stage is completed by the electric hinge. Specifically, the unlocking stage includes the full locking stage and the half locking stage. When the self-priming lock is performing the unlocking operation, the trunk door will enter the half locking state from the full locking state. When the half locking signal disappears, the trunk lock exits the half locking state and enters the full opening stage.

[0107] In this embodiment, in order to achieve smooth operation of the car door in the fully open stage, the ECU will control the electric hinge to drive the car door to open to the fully open position to prevent the car door from falling rapidly under the action of gravity and hitting the car body, causing impact on the vehicle.

[0108] It should be noted that if it is detected that the self-priming lock cannot be unlocked smoothly during the unlocking stage, the electric hinge can be controlled to intervene to assist the self-priming lock in unlocking the operation. Please refer to the specific implementation methods of steps S301 to S302 for details, which will not be repeated here.

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

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

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

[0112] In a feasible implementation, the vehicle door is a vehicle tailgate, and the vehicle tailgate is provided with two self-priming locks; the vehicle self-priming lock control method may further include the following steps:

[0113] S501: When the door lock control command is a closing control command, if only a half-lock signal of one of the two self-priming locks is received, the electric hinge is controlled to drive the rear tailgate of the vehicle to close.

[0114] In this embodiment, considering that the vehicle door is a tailgate, in order to ensure the firmness of the tailgate when it is closed, two self-priming locks are set on both sides of the tailgate, and locking mechanisms corresponding to the two self-priming locks are respectively set on the two side panels of the vehicle. Then, the tailgate is locked together by the locking mechanisms on both sides to ensure the safe use of the tailgate.

[0115] In this embodiment, if the ECU receives half-lock signals from two self-priming locks at the same time within a preset time interval while controlling the closing of the tailgate, it is considered that the tailgate has successfully reached the half-locked position, and then controls the two self-priming locks to perform the locking operation.

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

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

[0118] In this embodiment, after the ECU controls the electric hinge to drive the tailgate of the vehicle to close for a driving time of 500ms, regardless of whether the half-locking of the other self-priming lock is detected, it will control the two self-priming locks to perform the locking operation, that is, control the driving motors of the two self-priming locks to run in the corresponding target rotation direction until the half-lock signals and full-lock signals of the two self-priming locks are triggered, and then determine that the locking operation is completed, and then control the driving motors of the two self-priming locks to reset.

[0119] In this embodiment, by controlling the electric hinge to perform auxiliary closing when only a half-lock signal from one self-priming lock is received, on the one hand, the electric hinge can assist in the smooth closing of the tailgate of the vehicle when the self-priming torque of the self-priming lock is insufficient; on the other hand, it can ensure that the two self-priming locks can perform self-priming operations synchronously, improve the self-priming effect, and avoid excessive load on the drive motor caused by the locking operation of a single self-priming lock.

[0120] In a feasible implementation manner, in order to ensure that the self-priming lock can operate normally when the power is turned on again after power failure, the vehicle box self-priming lock control method may further include the following steps:

[0121] S601: When the self-priming lock is powered on again after being powered off, a half-lock signal and a full-lock signal of the self-priming lock are obtained.

[0122] In this embodiment, after the ECU detects that the self-priming lock is powered on again, it will detect the half-lock signal and the full-lock signal of the self-priming lock, and then determine whether the self-priming 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]

[0126] It should be noted that "1" indicates the presence of a corresponding signal, and "0" indicates the absence of a corresponding signal. Specifically, when both the half-lock signal and the full-lock signal are detected, it means that the door is in a fully locked state, at which point the self-priming lock's drive motor may have been reset or may not have been fully reset; when only the half-lock signal is detected, it means that the door is in a half-locked state, at which point the self-priming lock may be powered off during the locking process or during the unlocking process; when both the half-lock signal and the full-lock signal are detected, it means that the door is in a fully open state.

[0127] In this embodiment, considering that the power is cut off when the vehicle door is in the fully open state, it has no effect on the self-priming lock. Therefore, when it is detected that neither the half lock signal nor the full lock signal exists, it is regarded as normal and there is no need to operate the self-priming lock. If the second door lock control command triggered by the user through the preset button is received again, the locking operation is performed normally.

[0128] S602: When a half-lock signal and / or a full-lock signal is detected, the self-priming lock is kept inactive until a second door lock control instruction triggered by the user for the vehicle door is received, and the self-priming lock is controlled to perform an unlocking operation.

[0129] In this embodiment, it is considered that the power failure when the car door position is in a semi-locked state or a fully locked state will affect the self-priming lock, that is, the self-priming lock is abnormally powered off during operation. Specifically, if the car door position is in a semi-locked state, it means that the pawl in the locking mechanism of the self-priming lock has not completely disengaged from the ratchet, and the ratchet is still in a semi-locked state; if the car door position is in a fully locked state, the pawl may be stuck, so that the ratchet cannot return to its position normally. Therefore, when it is detected that both the semi-lock signal and / or the fully locked signal exist, in order to avoid the self-priming lock running in the wrong direction and failing to lock smoothly, the self-priming lock controller will not control the self-priming lock to do anything after power is restored, so that the car door remains in a semi-locked or fully locked state until the self-priming 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 then controls the self-priming lock to perform an unlocking operation to open the car door to the fully open position.

[0130] In this embodiment, by detecting the half lock signal and the full lock signal of the self-priming lock after the self-priming lock is powered on again, the self-priming lock can be powered on again in the event of an abnormal power outage, and the unlocking operation can be uniformly performed to ensure the normal operation of the self-priming lock, thereby avoiding abnormal operation of the self-priming lock.
