In the driving process of the vehicle, the safety coefficient of passengers can be effectively improved by correctly wearing the safety belt. However, in an actual riding process, when a person is present in the driver seat and the passenger seat and does not wear the seat belt, a warning is provided on the instrument panel. However, when the seat belt is not worn by the occupant at another position, the display is not performed on the instrument panel. Even if some vehicles are prompted, the passengers cannot effectively wear the safety belts accurately and effectively in the driving process of the vehicles. For example, some occupants fasten seat belts from behind the seat in order to escape the automatic warning sound on the vehicle. For this situation, the driver or other service personnel on the vehicle cannot timely find that the seat belt is not properly worn by the occupant.
Based on this, referring to fig. 1, an embodiment of the present invention provides a control method for vehicle seatbelt wearing. The implementation process of the embodiment comprises the following steps:
and S11, acquiring pressure data and image data on the seat.
In the embodiment of the application, the pressure data on the seat is collected in real time through the pressure sensor arranged below the seat. A first image of the front of the seat is then acquired by a camera positioned in front of the seat and a second image of the side of the seat is acquired by a camera positioned to the side of the seat. In some embodiments, after the pressure sensor detects the pressure data, the control signal is transmitted through the CAN to control the camera to operate. In other embodiments, the pressure sensor and the camera are synchronously controlled to enter the working state.
S12, judging whether the state of the safety belt on the seat accords with the automatic fastening condition according to the pressure data and the image data, if so, executing the step S121 and the step S122, otherwise, executing the step S123 and then continuing to execute the steps S11 and S12.
In the embodiment of the present application, after the pressure data is collected, whether the seat contains the analysis target is analyzed based on the pressure data. Whether the analysis target is contained on the seat can be judged according to the magnitude relation between the pressure data and the preset pressure value. For example, when there is no analysis target on the seat, the pressure value detected by the pressure sensor is 0; or as a prevention, clothes or a headrest, which are light-weight objects, the pressure data detected by the pressure sensor is close to 0. When a person is in the seat or a heavy object is placed on the seat, the pressure sensor can detect a larger pressure value. Therefore, the present embodiment can determine whether the seat contains the analysis target according to the magnitude relationship between the pressure data detected by the pressure sensor and the preset pressure value. When the pressure data detected in real time is larger than a preset pressure value, determining that the seat contains an analysis target; and when the pressure data detected in real time is less than or equal to the preset pressure value, determining that the seat does not contain the analysis target or contains an object with light weight.
After the analysis target is contained in the seat, the category of the analysis target on the seat is analyzed through the image information collected by the camera. For example, whether the analysis target is a passenger or a trunk. When the type of the analysis target is a target type (human), determining the position of a central shaft of the analysis target according to the pressure data, calculating the error between the position of the central shaft and the reference position, and when the determined error is within the error threshold range, determining that the safety belt at the current position meets the automatic locking condition. For example, the reference position is the center position of each seat, and when the occupant is located at the very center of the seat, the position of the center axis of the occupant almost coincides with the center position of the seat, and at this time, the error is approximately equal to zero, and it can be determined that the seat belt in the current position meets the automatic locking condition. When a passenger is located at a position between two seats, namely, when one passenger sits on two seats, the central shaft position of the passenger is located at the junction of the two positions, the error between the central shaft position and the central position of the seats is the largest at the moment, namely, the error does not belong to the error threshold range, and therefore, the safety belt at the current position is determined not to be in accordance with the automatic locking condition.
After determining that the seat belt state meets the automatic tightening condition, step S121 and step S122 are executed.
And S121, calculating the motion trail of the safety belt according to the image data.
In the embodiment of the application, the shape of the passenger on the current seat, such as the shape of the person with a small or large size, is analyzed according to the first image acquired by the front camera and the second image acquired by the side camera. And calculating the motion trail of the safety belt according to the determined morphological characteristics. For example, when the passenger is fat, the radian of the motion trajectory of the seat belt should be increased to avoid the seat belt moving process to poke the passenger, thereby causing a bad riding experience for the passenger. When the passenger is thin, the radian of the motion track of the safety belt should be reduced so as to shorten the moving route of the safety belt and accelerate the locking process of the safety belt.
And S122, controlling a safety belt actuating mechanism to fasten the safety belt on the seat according to the motion track.
In the embodiment of the application, after the running track of the safety belt is obtained, the safety belt is controlled by the safety belt executing mechanism to run in the running track, and then the locking state is achieved.
After determining that the seat belt state does not satisfy the automatic tightening condition, step S123 is executed.
And S123, generating prompt information, wherein the prompt information is used for prompting the passenger on the seat to adjust the position. For example, since the occupant sits between the two positions and the automatic tightening condition is not satisfied, after the occupant performs the position adjustment by the voice prompt, the steps S11 and S12 are re-executed until the locking operation of the seat belt at the current position is completed.
Before the above embodiment is executed, the vehicle state needs to be acquired, that is, whether the vehicle is in a startable state or an ignition state is judged, and the subsequent steps are executed according to the acquired vehicle state, so as to ensure that a passenger can wear the seat belt accurately and effectively in time in the vehicle driving process, and simultaneously, the execution workload of the seat belt control device can be reduced. For example, as shown in fig. 2, it is detected whether the vehicle is in READY state, i.e., whether it is in a startable state or an ignition state, and when it is not in READY state, the operation of automatically fastening the seat belt is not performed; when the seat is in a READY state, judging whether a person exists on the seat, if no person exists, not executing the operation of automatically fastening the safety belt; if the personnel exist, judging whether the position of the personnel on the current seat meets the requirement, for example, whether the position is in the middle of the seat, and if the position meets the requirement, executing the operation of self-fixing the safety belt so as to self-fix the safety belt; if the position requirement is not met, the operation of automatically fastening the safety belt is not executed, voice prompt information is generated to prompt the current passenger to adjust the position, and after the position is adjusted, the position judgment process is repeatedly executed until the safety belt of the passenger finishes the fastening operation.
Referring to fig. 3, an embodiment of the present invention provides a control system for vehicle seatbelt wearing, including:
and the pressure sensing unit is arranged below the seat and is used for acquiring pressure data on the seat.
The image acquisition unit comprises a front camera and a side camera which are all used for acquiring the image data on the seat. Specifically, the front camera is used for acquiring a first image of the front of the seat; the side camera is used for collecting a second image of the side of the seat.
And the processing unit is used for judging whether the state of the safety belt on the seat meets the automatic fastening condition or not according to the pressure data and the image data, if so, calculating the motion trail of the safety belt according to the image data, otherwise, generating prompt information, wherein the prompt information is used for prompting a passenger on the seat to adjust the position.
In the execution process of the unit, after the pressure data is obtained, whether the seat contains the analysis target or not is analyzed according to the pressure data. Whether the analysis target is contained on the seat can be judged according to the magnitude relation between the pressure data and the preset pressure value. For example, when there is no analysis target on the seat, the pressure value detected by the pressure sensor is 0; or the light objects such as clothes or a headrest, the pressure data detected by the pressure sensor is close to 0. When a person is in the seat or a heavy object is placed on the seat, the pressure sensor can detect a larger pressure value. Therefore, the present embodiment can determine whether the seat contains the analysis target according to the magnitude relationship between the pressure data detected by the pressure sensor and the preset pressure value. When the pressure data detected in real time is larger than a preset pressure value, determining that the seat contains an analysis target; and when the pressure data detected in real time is less than or equal to the preset pressure value, determining that the seat does not contain the analysis target or contains an object with light weight.
After the analysis target is contained in the seat, the category of the analysis target on the seat is analyzed through the image information collected by the camera. For example, whether the analysis target is a passenger or a trunk. When the type of the analysis target is a target type (human), determining the position of a central shaft of the analysis target according to the pressure data, calculating the error between the position of the central shaft and the reference position, and when the determined error is within the error threshold range, determining that the safety belt at the current position meets the automatic locking condition. For example, the reference position is the center position of each seat, and when the occupant is located at the very center of the seat, the position of the center axis of the occupant almost coincides with the center position of the seat, and at this time, the error is approximately equal to zero, and it can be determined that the seat belt in the current position meets the automatic locking condition. When a passenger is located at a position between two seats, namely, when one passenger sits on two seats, the central shaft position of the passenger is located at the junction of the two positions, the error between the central shaft position and the central position of the seats is the largest at the moment, namely, the error does not belong to the error threshold range, and therefore, the safety belt at the current position is determined not to be in accordance with the automatic locking condition.
After the condition that the state of the safety belt on the seat meets the automatic fastening condition is determined, the shape of the passenger on the current seat is analyzed according to the first image collected by the front camera and the second image collected by the side camera of the seat, and then the movement track of the safety belt is calculated according to the determined shape characteristics. For example, when the passenger is fat, the radian of the motion trajectory of the safety belt should be increased, so as to avoid the movement process of the safety belt from poking the passenger, thereby causing a bad riding experience to the passenger. When the passenger is thin, the radian of the motion track of the safety belt should be reduced so as to shorten the moving route of the safety belt and accelerate the locking process of the safety belt. And after the running track of the safety belt is determined, the safety belt is controlled to run in the running track through the safety belt actuating mechanism, and then the locking state is achieved.
When it is determined that the seat belt state does not satisfy the automatic tightening condition, a prompt message is generated for prompting the occupant of the seat to adjust the position. For example, the passenger sits between two positions, and the automatic fastening condition is not met, so after the voice prompt, the passenger performs position adjustment, and then the steps of pressure data acquisition and image acquisition are executed again until the safety belt at the current position completes the locking operation.
And the control unit is used for controlling the safety belt actuating mechanism to fasten the safety belt on the seat according to the motion trail.
Specifically, the safety belt actuating mechanism comprises a hook popping device, a hook and a bayonet, wherein the hook popping device is fixed on one side of the seat, the hook is movably arranged on the safety belt, and the bayonet is fixed on the other side of the seat. For example, a seat located at the left rear of the vehicle, in which case a hook pop-up device of the seat is fixed at an upper left position of the seat back; the bayonet is fixed at the lower position of the right side of the seat backrest; the hook is movably arranged on the safety belt and used for pulling the safety belt to extend or contract in the movement process. In some embodiments, a servo motor is provided on the hook ejecting device. When the control unit does not receive the movement track of the safety belt, the hook is fixed on the hook popping device; when the control unit receives the movement track of the safety belt, the control unit controls a servo motor in the hook popping device to drive the hook to pop up, so that the hook is locked with the bayonet after running along the movement track, and the locking operation of the safety belt is completed.
