Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
At present, the lifting operation of the door glass is mainly judged according to the state of the door; when the door is opened, the door glass is slightly lowered, so that the top edge of the door glass is often interfered with the sealing strip, abnormal sound is generated, and the sealing strip is damaged.
On the basis, the lifting control of the door glass can be performed according to the unlocking state of the vehicle at present so as to control the door glass before judging the door state. However, the inventor researches that the method has redundant application, so that the door glass is frequently lifted in unnecessary occasions, and the sealing strip is worn. For example, a user may not open a door to the interior of the vehicle after unlocking the vehicle, which may only store items from the trunk. However, the door glass is controlled to slightly descend in advance based on the unlocking state of the vehicle, the door glass is controlled to slightly descend after the subsequent locking, the door is not opened or closed in the process, and the lifting control of the door glass belongs to redundant operation.
Based on the above, the lifting control method, the lifting control device and the electronic equipment for the frameless door glass provided by the embodiment of the invention are used for realizing the lifting control of the door glass not by utilizing the unlocking state of the vehicle, but under the condition that the vehicle is in the unlocking state, the change trend of the door is known through the invisible handle state and the current condition of the door, so that the lifting control of the door glass in advance is realized, and the technical problems of damage to the sealing strip and hysteresis in the control of the door glass in the prior art are solved on the basis of ensuring the lifting reliability of the door glass.
For the sake of understanding the present embodiment, a method for controlling the lift of a frameless door glass according to an embodiment of the present invention will be described in detail. The embodiment of the invention can be applied to door glass lifting control of a frameless door and door glass control of a framed door. For ease of description, in the following embodiments, a door is referred to as a frameless door.
Fig. 1 is a flowchart of a method for controlling lifting of a frameless door glass according to an embodiment of the present invention.
Referring to fig. 1, the method includes the steps of:
step S102, if the current vehicle is in an unlocking state, acquiring the current time state of the vehicle door and the telescopic state of an invisible outer handle arranged on the vehicle door.
The embodiment of the invention does not directly control the lifting of the door glass based on the unlocking state of the current vehicle, and at the moment, the current moment state of the door and the telescopic state of the invisible outer handle are determined when the current vehicle is unlocked; the state of the vehicle door is an open state or a closed state, and the vehicle door at the current moment can be opened or closed.
Step S104, predicting the next moment state of the vehicle door based on the telescopic state.
In addition, at present, for the aesthetic appearance of the vehicle, a part of the vehicle is provided with a hidden outer handle outside the door. When no user pulls the invisible outer handle outside the vehicle door, no handle part with a convex display is arranged outside the vehicle door. A user or other control equipment outside the door can control the state change of the invisible outer handle first, and then the aim of closing or opening the door through the handle is fulfilled. For example, the door may be opened at the next time when the hidden outer handle is in the extended state, and the door may be closed at the next time when the hidden outer handle is in the retracted state, but no matter what telescopic state the hidden outer handle is, the opening or closing state of the door at the current time is not affected. The shape and construction of the invisible outer handle and the working principle can be known to a person skilled in the art and are not described in detail herein.
It will be appreciated that the concealed outside handle can be sprung to an extended position only if the current vehicle is unlocked, or that the door glass can be controlled to drop slightly only if the current vehicle is unlocked and based on the extended position of the concealed outside handle.
Step S106, if the current time state of the vehicle door is closed and the next time state is open, determining that the vehicle door has a door opening change trend.
It can be appreciated that the trend of the vehicle door can be known from the current state of the vehicle door and the predicted next state. For example, if the current door is closed, it is predicted that the door will be opened at the next moment, the door has a tendency to be opened, but the door is still in a closed state at this moment.
And S108, controlling the door glass to perform micro-descending operation based on the door opening change trend, the top edge of the door glass and the preset lifting position.
And if the vehicle door has a change trend of opening the door, performing micro-drop control on the vehicle door glass according to the relative relation between the top edge of the vehicle door glass and the preset lifting position.
In the practical preferred embodiment, the inventor researches and discovers that under the premise of unlocking the vehicle, the change trend of the vehicle door can be predicted in advance before the vehicle door is opened or closed at the next moment through the telescopic state of the invisible outer handle, so that the lifting control of the vehicle door glass is performed in advance, the reliability of the lifting of the vehicle door glass is ensured, redundant lifting operation of the vehicle door glass is avoided, and abrasion is reduced. Preferably, according to the closing state of the door at the current moment and the opening state of the door at the next moment, the current closed door is known to have the change trend of opening, and further the door glass is controlled in advance to perform micro-descent operation.
In some embodiments, the state of the door at the next moment can be predicted according to the telescopic state of the invisible outer handle so as to control the door glass to lift in advance, thereby avoiding the problem of lift control delay. The step S104 further includes:
step 1.1), if the invisible outer handle is in an extending state, the next moment state of the vehicle door is predicted to be open.
Step 1.2), if the invisible outer handle is in a contracted state, the next moment state of the vehicle door is predicted to be closed.
Based on the working principle of the invisible outer handle, on the premise that the vehicle is in an unlocked state, a user manually pulls the invisible outer handle, the invisible outer handle is in an extending state, the invisible outer handle protrudes outside the vehicle door rather than is invisible, and the state of the vehicle door is not changed. Illustratively, when the vehicle is currently unlocked and the door is closed, a user manually operates the hidden outside handle to pull up, the hidden outside handle is in an extended state, the door is still closed, and the user opens the door based on the extended state handle at the next moment.
In some embodiments, the extended state of the hidden outside handle is determined based on the unlocked state of the door and the operational state of the hidden outside handle or the operational state of the door inside handle.
The door inner handle is arranged inside the door, and when a passenger pulls the door inner handle, the door inner handle is opened by a certain angle, and the door is unlocked at the moment, but the door is not opened yet. If the user pulls the inner handle again within a preset time, the door is opened. In the practical application process, if the vehicle body controller fails, when the user pulls the inner handle, the outer handle originally hidden in the vehicle door is protruded to be in an extending state, and the vehicle door glass is controlled to be slightly lowered to a preset lifting position at the moment, and the vehicle door glass cannot be lifted until the failure is relieved. The invisible outer handle in the embodiment of the invention is in an extended state when a user acts on the invisible outer handle, namely, pulls up the invisible outer handle on the basis that the vehicle is in an unlocked state, namely, the vehicle unlocked state and the extended state of the invisible outer handle belong to two different signal states.
As another alternative embodiment, the state of the invisible outer handle can be controlled by a remote control key and a central control system, and when a user uses the remote control key to unlock the whole vehicle, the invisible outer handle can automatically pop up; when a user uses the central control system to unlock the whole vehicle, the invisible outer handle can also pop up automatically. In this embodiment, when the user uses the remote control key or the central control system to control the locking of the vehicle, the hidden outer handle automatically contracts, or when the speed of the vehicle reaches a preset value, the central control system automatically controls the locking of the vehicle, and at this time, the hidden outer handle automatically contracts.
In some embodiments, as shown in fig. 2, the door control module for performing the method according to the embodiment of the present invention may include a plurality of door glass that respectively controls the corresponding door glass, and in particular may include a FRONT RIGHT (FR) door control module, a FRONT LEFT (FL) door control module, a REAR RIGHT (REAR RIGHT, RR) door control module, and a REAR LEFT (RL) door control module. The door control modules are each connected to a body control module (Body Control Module, BCM) for monitoring and controlling functions associated with the vehicle body (e.g., vehicle lights, windows, door locks).
In an actual application scenario, when the driver controls the action state of the inner handle through the central control system (the vehicle body control module), the method of the embodiment further comprises the step of receiving the state signals of the invisible outer handle and the inner handle of the vehicle door, which are forwarded by the vehicle body controller, wherein the state signals of the inner handle of the vehicle door are determined by detecting the action state of the inner handle of the vehicle door through the micro switch.
It can be understood that the central control system controls the action of the inner handle, then the state change of the inner handle is detected by utilizing the contact switch connected with the inner handle of the vehicle door, the state signal of the inner handle of the vehicle door is forwarded to the corresponding vehicle door control module through the vehicle body control module, and the vehicle door control module analyzes the state signal and starts the micro-descent function of the vehicle door glass. For example, a status signal of the inside handle of the rear left door may be forwarded to the rear left door control module. The vehicle body control module does not process an inner handle signal, an outer handle signal and a vehicle door state signal and only plays a role in forwarding to the vehicle door control module.
In the actual application process, the door can be opened by two actions of the handle in the door, the first action of the handle in the door is used for unlocking the vehicle, the second action of the handle in the door is used for opening the door, the user 1 can control the door to be unlocked through the central control system, and at the moment, the user 2 can realize the door opening by one action of the handle in the door.
As an alternative embodiment, the non-driving occupant may control the actuation of the door inner handle while detecting a change in the state of the inner handle using a contact switch connected to the door inner handle, and the door control module directly receives a signal of the state of the door inner handle.
If the handle in the vehicle door fails, the user cannot manually open or close the vehicle door, and the driver can control the corresponding vehicle door through the central control system, so that multiplexing is realized, and reliability is ensured.
In some embodiments, if the vehicle body controller fails, in order to ensure normal opening of the vehicle door, the user can freely go in and out, and when the vehicle body controller is in a failure state and the vehicle door inner handle is in an action state, the invisible outer handle is driven to extend, and the vehicle door glass is controlled to slightly drop to a preset lifting position and cannot rise. For example, if the vehicle body controller fails, the user in the vehicle can act on the inner handle of the vehicle door, and at the moment, the invisible outer handle is driven by the inner handle of the vehicle door to be in an extending state, and the glass of the vehicle door is controlled to slightly descend to a preset lifting position. At this time, the invisible outer handle cannot be retracted and the door glass cannot be lifted above the preset lifting position until the vehicle body controller is restored to normal.
In some embodiments, based on the door opening trend of the vehicle door, the vehicle door glass can be subjected to micro-lowering operation in advance, so that the hysteresis control micro-lowering glass cannot rub against the sealing strip of the side wall, and abnormal sound is generated. The step S108 may be further implemented by the following steps, including:
and 2.1), if the top edge of the door glass is higher than the preset lifting position, controlling the door glass to slightly descend to the preset lifting position according to the door opening change trend.
Step 2.2), if the top edge of the door glass is lower than or at the preset lifting position, keeping the door glass motionless at the moment according to the door opening change trend, and not performing micro-descending operation on the door glass.
As an alternative embodiment, if the top edge of the door glass is higher than the preset lifting position and the door is in the open state at this time, the door glass is slightly lowered to the preset lifting position.
As another alternative embodiment, if the top edge of the door glass is lower than the preset lifting position and the door is in the open state at this time, the door glass is kept still at this time, and no micro-lowering operation is performed on the door glass.
It will be understood that microliters refers to the movement of the door glass from the preset lifting position to the topmost point where the door glass can rise, which corresponds to the complete closing of the door glass, and micro-drop refers to the descent of the door glass from the topmost point where it is completely closed to the preset lifting position.
In some embodiments, the method of the above embodiments further includes:
step 3.1), if the door glass is at the preset lifting position, the current time state of the door is closed, and the next time state of the door is closed, controlling the door glass to lift from the preset lifting position to a preset highest point of the door glass which is allowed to lift, wherein the preset highest point of the door glass which is allowed to lift can be understood as the topmost end of the door glass which can lift, namely if the door glass lifts to the preset highest point, the door glass is completely closed.
In the actual application process, the application scenario that may occur for the above step 3.1) may include the following cases:
1) The user controls the action of the inner handle of the car door, the control of the central control system or the control of the remote key to lock the car door, and the invisible outer handle is in a contracted state at the moment, namely, the state of the car door at the next moment is predicted to be closed, so that the control strategy of the step 3.1) is executed.
2) After the user controls the handle in the vehicle door to act once, but after a first preset time period (for example, 1 s), the user does not act on the handle in the vehicle door for the second time, at the moment, the vehicle door is still not opened, and after a second preset time period (for example, 1 s), the action signal for controlling the handle in the vehicle door is disappeared, namely, the state of the vehicle door at the next moment is predicted to be closed, and then the control strategy of the step 3.1) is executed.
In some embodiments, the door inner handle may fail, and the door glass is correspondingly controlled to ensure the reliability of vehicle running under the failure condition, and the method further comprises the following steps:
and 4.1), if the handle in the vehicle door is in an action state and the action state signal is not disappeared all the time for the third preset time, controlling the vehicle door glass to rise from the preset lifting position to the preset highest point of the allowed rising of the vehicle door glass.
In an actual application scene, the door control module continuously detects the action signal of the door inner handle, the action signal of the door inner handle is controlled to be continuously not disappeared for a third preset time period (for example, 2 s), the invisible outer handle is in a contracted state at the moment, the door is not opened, namely, the state of the door at the next moment is predicted to be closed, and the control strategy of the step 4.1) is executed after the fourth preset time period (for example, 2 s) is delayed. It should be noted that, in the present case, there may be a failure of the door inner handle, if a non-driving occupant such as a child continuously operates the door inner handle, and thus the door inner handle is failed, when this condition is satisfied, a failure processing is performed, and the operation signal of the door inner handle is ignored until the operation signal is again valid.
If the door glass is at or below the preset lifting position and the invisible outer handle is in the extended state, that is, the door is in the open state at the next moment (or the current moment of the door is in the open state), the door glass cannot be lifted up or the top edge of the door glass cannot be lifted up above the preset lifting position.
As another alternative embodiment, if the invisible outside handle is in a retracted state, the door is in a closed state at the current time, and the door handle in the vehicle has no action signal, according to the previous embodiment, the door glass is controlled to be slightly raised to the highest point of allowable raising. On the basis, a user in the vehicle can lower the door glass to any position according to the requirement, and can control the lowered door glass to rise to any position according to the requirement.
As shown in fig. 3, an embodiment of the present invention provides a lifting control device for a frameless door glass, including:
the acquisition module is used for acquiring the current moment state of the vehicle door and the telescopic state of the invisible outer handle arranged on the vehicle door if the current vehicle is in the unlocking state;

In some embodiments, the control module is further specifically configured to control the door glass to rise from the preset lifting position to a preset highest point where the door glass is allowed to rise if the door glass is at the preset lifting position and the current time state of the door is closed and the next time state is closed.
In some embodiments, the extended state of the hidden outside handle is determined based on the unlocked state of the door and the operational state of the hidden outside handle or the operational state of the door inside handle.
In some embodiments, the control module is further specifically configured to, if the vehicle body controller fails and the door inner handle is in an action state, enable the hidden outer handle to be in an extended state, and control the door glass to slightly descend to the preset lifting position and not ascend.
In some embodiments, the control module is further specifically configured to receive status signals of the invisible external handle and the internal handle of the vehicle door forwarded by the vehicle body controller, where the status signals of the internal handle of the vehicle door are determined by detecting an action state of the internal handle of the vehicle door through the micro switch; or directly receives a status signal of the handle in the vehicle door.
