Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to illustrate the technical scheme of the invention, the following description is made by specific examples.
The embodiment of the invention provides a vehicle door protection method, which is mainly used for preventing the problem that a vehicle door is damaged when the vehicle door is closed if a safety belt is exactly positioned at a position where the vehicle door is blocked under the conditions that the safety belt is not fully retracted or loosened and the like. The method can be integrated into a vehicle body domain controller of a vehicle, and can be combined with a camera, a seat controller and the like in a cabin of the vehicle to realize the protection of the vehicle door.
Fig. 1 is a schematic implementation flow chart of a vehicle door protection method according to an embodiment of the present invention, and referring to fig. 1, the method includes:
step S101, cabin state information of a vehicle is acquired.
In the present embodiment, cabin state information is mainly information related to "there is a risk of the door pinching the seat belt", such as the state of the door, the state of the seat belt, whether the seat is a passenger, or the like. Such information may be collected by a camera in the cabin or by a sensor (e.g., door sensor, seat belt sensor, seat weight sensor, etc.).
Step S102, judging whether each door of the vehicle meets preset safety belt anti-pinch judging conditions according to cabin state information.
In the present embodiment, the seatbelt pinch prevention judging condition is used to determine whether "there is a risk of pinching the seatbelt with the door".
Optionally, the cabin status information includes a status of the seat belt and a status of the door;
judging whether each door of the vehicle meets a preset safety belt anti-pinch judging condition according to the cabin state information, including:
if the state of any one of the doors is an open state and the state of the seat belt of the seat at the corresponding position of the door is an unlocked state, the door is judged to meet the belt anti-pinch judgment condition.
In this embodiment, the seat belt is unlocked, and the seat belt may be located in an area where the closing of the door is blocked, and the door is opened, so that the door may be damaged by the clamping of the seat belt due to the closing of the door, i.e., the risk of clamping the seat belt by the door is described above. Except for this case, neither the door nor the belt is satisfied, and there is no risk of the door pinching the belt, and no subsequent judgment is necessary. By judging the preconditions, the system can be prevented from performing a large number of invalid detections.
Step S103, if any door of the doors satisfies the belt pinching prevention judgment condition, judging whether the seat belt of the seat at the corresponding position of the door is located in a preset area for obstructing the closing of the door.
In this embodiment, as shown in fig. 2, when the safety is not fully retracted, the seat belt or the seat belt latch may be located at the vertical edge and bottom of the door frame, which is a region where the door is blocked from closing because the door may clamp the seat belt or the seat belt latch to cause damage to the door and the vehicle body.
And step S104, if yes, carrying out safety belt anti-clamping protection on the vehicle door.
In this embodiment, the safety belt anti-pinch protection may be performed on the vehicle door directly by voice prompt, or may be performed when the vehicle door performs a closing action, for example, by performing voice prompt "please notice" through power amplification in the vehicle and outside the vehicle at the same time, so that the safety belt is not fully retracted. The intelligent control door can also be used for controlling the door not to be completely closed when a user controls the door to be closed in or out of the automobile. Both of these approaches can avoid the user from unknowingly closing the door and causing damage to the door.
Here, when the closing action of the door is detected, the control of the door not to be completely closed may be achieved by:
when the closing action of the vehicle door is detected, acquiring the opening angle of the vehicle door;
if the opening angle is smaller than a predetermined angle threshold, an obstruction command is sent to the electric control mechanism of the vehicle door so that the electric control mechanism applies a force for obstructing closing to the vehicle door.
In this embodiment, the analysis may be performed through the visual image, and it is detected whether the user controls to close the door, and if it is detected that the user controls to close the door, it is determined that the door performs the closing operation. Alternatively, whether the user manipulates the door to be closed may be detected by an angle sensor installed at the door, and when the angle of the door is continuously reduced for a certain period of time, it is determined that the door performs the closing operation.
Currently, doors on many vehicles are electric doors. The electric control mechanism of the electric vehicle door can be utilized, when the opening angle of the vehicle door is smaller than a certain angle threshold value, the electric control mechanism is used for controlling the vehicle door to open outwards, namely, the closing-blocking force is applied to the vehicle door, so that the vehicle door rebounds after being closed to a certain degree, and the vehicle door cannot be completely closed, and the vehicle door is protected.
For the non-electric vehicle door, a blocking mechanism can be additionally arranged, and when the blocking mechanism is started, the vehicle door can only be closed to a certain angle and cannot be completely closed. The actuation of the blocking mechanism is controlled by the door protection logic described above, such as only when the door is "belt anti-pinch protected".
According to the embodiment of the invention, whether each door of the vehicle meets the preset safety belt anti-clamping judging condition is judged according to the cabin state information of the vehicle, so that whether the risk of clamping the safety belt by the door exists at each door can be obtained; if the risk exists, whether the safety belt of the seat at the corresponding position of the vehicle door is located in a preset area for preventing the vehicle door from being closed or not is further judged, if yes, the safety belt is subjected to anti-clamping protection on the vehicle door, and therefore the vehicle door is prevented from being damaged due to clamping of the safety belt when the vehicle door is closed.
Fig. 3 is a schematic flow chart of another implementation of a method for protecting a vehicle door according to an embodiment of the present invention, and referring to fig. 3, the method includes:
step S301, cabin state information of a vehicle is acquired.
The implementation manner of this step may be referred to the related description in the embodiment of fig. 1, and this embodiment will not be described in detail.
Step S302, judging whether each door of the vehicle meets preset safety belt anti-pinch judging conditions according to cabin state information.
The implementation manner of this step may be referred to the related description in the embodiment of fig. 1, and this embodiment will not be described in detail.
Step S303, if any door in the doors meets the safety belt anti-clamping judging condition, judging whether the safety belt of the seat at the corresponding position of the door is completely retracted; if the seat belt is completely retracted, judging that the seat belt of the seat at the corresponding position of the vehicle door is not positioned in the area for preventing the vehicle door from closing; if the vehicle door is not fully retracted, an image of the area blocking the closing of the vehicle door is acquired, and whether the safety belt of the seat at the corresponding position of the vehicle door is positioned in the area blocking the closing of the vehicle door is judged based on the image.
In this embodiment, the pull-out/retract length of the webbing may be detected by a detector mounted on the webbing mechanism, the detector including a controller for controlling the motor to drive the spool of the webbing to rotate, and a hall sensor for transmitting a detected signal related to the rotation of the spool to the controller, the controller obtaining the pull-out/retract length of the webbing based on the signal.
It will be appreciated that the seat belt may be located in an area where door closure is impeded only if the seat belt is not fully retracted. Here, when the unrecovered length of the webbing is greater than a certain threshold value, it may be determined that the webbing is not completely retracted.
Further, when the safety belt is not completely retracted, the safety belt is not necessarily located in a blocking door closing area, and may be located in a seat upper position, and the positions do not affect the closing of the door.
Step S304, if yes, detecting the position of a safety belt of a seat corresponding to the vehicle door in a subarea of the area for blocking the vehicle door closing according to the image for blocking the vehicle door closing area, and determining an angle threshold value based on the subarea position; or detecting the unretracted length of the safety belt of the seat at the corresponding position of the vehicle door; an angle threshold is determined based on the unretracted length.
As shown in fig. 4, the door closing region can be divided into two sub-regions, namely a door frame bottom sub-region (sub-region 1) and a door frame vertical edge sub-region (sub-region 2).
When the seat belt is located in the sub-zone 1, it is closer to the rotation axis of the door, so that the angle threshold should be set to be larger in order to avoid the door from pinching the seat belt; similarly, when the safety belt is located in the subarea 2, the safety belt is far away from the rotation axis of the vehicle door, and the angle threshold value can be set smaller. Through the dynamic setting of the angle threshold value, the door can be closed to the greatest extent on the premise of ensuring the safety of the door, and the experience of a user when the door is closed is further improved.
For the angle threshold, it may also be determined by detecting the unretracted length of the seat belt. If the unretracted length is short and only the subarea 2 can be reached, a smaller angle threshold value is used; if the unretracted length is longer, it is possible to reach sub-region 1 and sub-region 2, and a larger angle threshold is used.
The division of the subareas is merely exemplary, and the division manner of the subareas may be freely set according to different vehicle types and different actual requirements, for example, the bottom of the door frame may be divided into a plurality of subareas. In particular, the present application is not limited to this.
Step S305, when the closing action of the vehicle door is detected, the opening angle of the vehicle door is obtained; if the opening angle is smaller than a predetermined angle threshold, an obstruction command is sent to the electric control mechanism of the vehicle door so that the electric control mechanism applies a force for obstructing closing to the vehicle door.
The implementation manner of this step may be referred to the related description in the embodiment of fig. 1, and this embodiment will not be described in detail.
The embodiment of the invention adopts a mode of combining an image recognition technology and an intelligent control technology, analyzes the safety belt states of a driver and a passenger, accurately judges the safety condition of the vehicle door body, reminds and protects the vehicle door body, avoids the problem of damage to the vehicle door body caused by incomplete retraction of the safety belt, realizes real-time state monitoring and protection of the vehicle, and can be widely applied to various vehicle types.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present invention.
