Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A seat belt monitoring system according to an embodiment of the first aspect of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a block diagram of a seat belt monitoring system according to an embodiment of the present invention, and as shown in fig. 1, a seat belt monitoring system 100 of an embodiment of the present invention includes a feature information detecting device 10, a telescopic length detecting device 20, and a processing device 30.
The characteristic information detection device 10 is used for detecting characteristic information of a seated object, and for example, various sensors are provided for each seat to detect weight, width, height, temperature, and the like; the telescopic length detection means 20 detects the telescopic length of the seat belt.
The processing device 30 may be disposed on the entire vehicle, or disposed at each seat position, and the actual disposition condition may be determined according to the complexity of the vehicle. The processing device 30 recognizes the character model of the driver or the passenger based on the characteristic information of the seated object. Specifically, whether a sitting object is a driver or not can be judged according to the characteristic information, misjudgment caused by the fact that an object similar to the weight of a human body is placed on the seat is avoided, if the sitting object is the driver or not, what type of body type of the driver or not is further judged, for example, an adult or a thin adult or a child or a thin child is judged, whether the safety belt at the position of the seat where the driver or not is tied or not is judged according to the stretching length of the character model and the safety belt, the lengths of the safety belts required by different character models are usually different, mapping relations between various character models and standard stretching lengths can be prestored, if the detected stretching length of the safety belt is within the range of the standard stretching length, the safety belt is considered to be tied, and if not, the safety belt is tied.
According to the safety belt monitoring system 100 provided by the embodiment of the invention, the character model of the driver and the passenger is identified according to the characteristic information, and the safety belt is monitored based on the character model of the driver and the passenger, so that compared with the method of judging whether the safety belt is fastened well only through weight, the safety belt monitoring system is higher in accuracy and avoids misjudgment.
Further, in some embodiments, as shown in fig. 2, the characteristic information detection apparatus 10 of the embodiment of the present invention includes a weighing module 11, a body temperature module 12, and a physical characteristic module 13. The weighing module 11 is configured to detect a weighing state of the seat, for example, detect a weighing weight change of the seat, and it is understood that the weight change may reflect whether there is a seated object and a gross weight of the seated object. The body temperature module 12 is used to detect the body temperature of a sitting object, and different articles have different temperatures, and even an animal body has different body temperatures, so that whether the sitting object is a human body, that is, whether the sitting object is a driver or a passenger can be determined according to the body temperature of the sitting object. The physical sign module 13 is configured to detect a physical sign of the driver and the passenger, where the physical sign may be a characteristic of the intrinsic performance of the human body, such as length, and in some embodiments, the physical sign of the driver and the passenger may include at least one of shoulder distance, leg distance, and body length, or other suitable characteristics that may characterize the body type of the driver and the passenger.
Specifically, the processing device 30 acquires information such as the weighing state of the seat, the body temperature of a sitting object, and the physical characteristics of a driver and a passenger, determines whether the sitting object exists on the seat according to the weighing state, if the weight of the seat is increased, the sitting object exists, otherwise, the sitting object does not exist, if no person is sitting at the position, the seat belt signal of the seat position is not processed, and a prompt signal indicating that whether the seat belt is fastened or not is not required to be determined at the seat position is sent; and determining whether the sitting object is a driver or not according to the body temperature of the sitting object, and determining a character model of the driver or the passenger according to the weighing state and the physical signs, namely, judging the body type of the driver or the passenger according to the information such as the weight, the body length, the shoulder distance, the leg distance and the like of the driver or the passenger. Various character models such as an adult or a thin adult or a child or a thin child can be defined in advance by character models different from each other by known characteristic information members, and if the standards of the various character models are not met, the character models are regarded as items to be carried with the vehicle. Therefore, when the safety belt is monitored, the person model to which the person belongs can be judged according to the characteristic information, and different safety belt stretching lengths are needed by different person models when the safety belt is fastened, so that the judgment accuracy can be improved.
In the embodiment, the processing device 30 determines a standard stretch length from the character model and a pre-stored type of the seat belt when monitoring the seat belt based on the character model, and determines that the seat belt is fastened when the stretch length of the seat belt coincides with the standard stretch length.
Among them, the types of seat belts for vehicles are classified into a pretensioned type, a three-point type, a rear type, and a seat belt on a child seat, among which the three-point type is most widely used. When the same passenger uses different types of safety belts, the length of the drawn safety belts is different, therefore, the standard stretching length of different safety belt types corresponding to various character models needs to be predefined, therefore, an information base of the relation of the safety belt types-the character models-the standard stretching length can be prestored, in order to avoid different sizes of the passenger body types, a certain safety belt stretching length judgment error range is allowed to exist, the information base is stored in the processing device 30, the stretching length detection device 20 sends a signal of the current actual stretching length of the safety belt to the processing device 30, and the processing device 30 comprehensively judges whether the passenger really ties the safety belt or not, so as to prevent some people from taking the possibility of tying the safety belt or prevent the system from misjudging that the safety belt is not tied when the seat places articles. When the vehicle leaves the factory, the processing device 30 is required to define the current seat belt type as a pre-stressed type, a three-point type, a rear-row type or other types.
In the case of a seat belt of a child seat, since the child seat is installed on the rear-mounted seat, this special type requires the driver to set himself/herself which seat of the vehicle uses the child seat, and in the embodiment of the present invention, as shown in fig. 3, the seat belt monitoring system 100 further includes an input device 40, the input device 40 is configured to receive a setting instruction, and the processing device 30 is configured to adjust the position of the seat belt to be monitored according to the setting instruction. For example, an on-board meter or multimedia or other device reminds a driver of whether a child seat is loaded in the vehicle when the vehicle is started to operate, the driver can enable the processing device 30 to acquire that a child safety seat is additionally installed at a certain seat position of the current vehicle through setting operation of the input device 40, and the child safety seat is regarded as special judgment processing, whether a safety belt of the child safety seat is fastened or not is judged according to definition of the child safety seat, or the safety belt of the seat is not monitored if the safety belt is ignored, or the safety belt is fastened at the position by default, so that misjudgment is avoided.
Specifically, the processing device 30 determines whether a seat is seated or not based on the characteristic information, and if no person is seated at the position, the processing device 30 does not process the seat belt signal at the seat position and sends a signal indicating that the seat position does not require a determination as to whether the seat belt is fastened or not; if the processing device 30 determines that the seat is seated at the position, it is first necessary to identify which seat is seated, and if there is a seat that is seated in other seats than the two seats of the front driver and the passenger, the processing device 30 sends information to a device such as an in-vehicle meter, and the device reminds the driver whether a child seat is mounted in the vehicle, so that the driver can make the processing device 30 obtain that the child seat is mounted at a certain seat position of the vehicle through a certain setting operation. After recognizing and processing the sitting signal, the processing device 30 compares a plurality of vital sign information of the drivers and passengers at each current position, such as weight, body temperature, shoulder distance, leg distance, body length and the like, with the information base of the character model stored in advance to judge the character model of each driver and passenger, and if the drivers and passengers recognize that the passengers are only carrying articles with the vehicle, the processing device sends out a signal that the seat position does not need to judge whether the safety belt is fastened; if the passenger is identified to be a valid passenger, comparing the character model of the driver and the passenger who are sitting at present with the relationship information base of the safety belt type, the character model and the safety belt stretching length of the passenger, if the safety belt stretching length exceeds the error range allowed by each judgment level, the passenger at the position is not fastened with the safety belt, the protection effect is reduced when the safety belt is stretched too long, the suspicion that the passenger is thrown on the safety belt to take a false situation when the safety belt is retracted too short exists, a certain potential safety hazard is caused in both cases, and the processing device 30 also sends a signal that the safety belt at the position of the seat is not fastened; if the belt extension is within the tolerance range allowed by each evaluation level, the processing device 30 signals that the seat position is good.
In some embodiments of the present invention, as shown in fig. 3, the seat belt monitoring system 100 further comprises a fastening state detection device 50, wherein the fastening state detection device 50 is used for detecting the fastening state of the seat belt, i.e. detecting whether the buckle of the seat belt can be in the locker; the processing device 30 is further configured to determine whether the seat belt at the seat position where the driver and the passenger are located is fastened in place according to the fastening state, so as to further ensure that the seat belt is fastened well. Fig. 4 is a schematic view showing the installation of the characteristic information detecting means 10, the telescopic length detecting means 20 and the fastening state detecting means 50 according to an embodiment of the present invention.
In an embodiment, the processing means 30 is further adapted to generate seat belt monitoring information based on a determination of the state of the seat belt at the seat position where the occupant is located, e.g. whether the seat belt at that position is fastened or not fastened. As shown in fig. 3, the safety belt monitoring system 100 according to the embodiment of the present invention further includes a projection device 60, where the projection device 60 is configured to project the safety belt monitoring information onto a display surface so that the traffic monitoring device can obtain the safety belt monitoring information.
Particularly, for monitoring whether drivers and passengers fasten safety belts on vehicles, at present, most of the monitoring cameras on the roads are high-definition cameras by means of capturing pictures and carrying out technical analysis when the drivers and passengers patrol on the roads or pass through the snapshot cameras in the driving process of the vehicles, and whether the drivers and passengers fasten the safety belts or not can be quickly and accurately identified through a mature image identification algorithm, or monitoring equipment is additionally arranged on each vehicle, but the image identification technology is also used for judging whether the drivers and passengers fasten the safety belts or not. However, the current legislation only requires the see-through clarity of the front windshield, the front windshield of the vehicle cannot be pasted with a glass protective film with characteristics of dark color, light reflection and the like, but does not require other vehicle windows, and many vehicle owners can paste glass protective films with characteristics of dark color, light reflection and the like for improving the sun-shading effect, so that even though high-definition cameras can only capture images of front row drivers and passengers, certain blind areas exist for monitoring rear row passengers, the recognition rate is reduced, if traffic image monitoring equipment is additionally arranged on each vehicle, personal privacy is invisibly invaded to a certain extent, especially private vehicles, and therefore the feasibility of pushing is not high.
In view of the above problem, the embodiment of the present invention can more intuitively and clearly understand which position the seat belt is not fastened at present by projecting the seat belt monitoring information to a Display surface such as a windshield through the projection device 60 such as a HUD (Head Up Display), wherein different seat positions are defined by different signals for easy recognition by the projection device 60, for example, if the projection device 60 receives the information that the seat belt at a certain position or at certain positions is not fastened sent by the processing device 30, the information is provided in the Display area of the Display surface, and if the information that the seat belts at all positions are fastened is received, the seat belts at all seat positions are fastened in the corresponding projection Display area. The traffic monitoring device can acquire the safety belt monitoring information provided by the vehicle through the high-definition camera, and the safety belt state of the vehicle can be judged more effectively and accurately.
In the embodiment of the present invention, as shown in fig. 3, the seatbelt monitoring system 100 further includes a reminder device 70, and the reminder device 70 is used for reminding when it is determined that the seatbelt at the seat position where the occupant is located is not fastened. For example, the vehicle-mounted instrument or other display devices of the vehicle are used for reminding, specifically, the vehicle-mounted instrument or the display device implements monitoring information transmitted by the detection processing device 30, and if information that the safety belt at a certain seat position or certain seat positions is not fastened is received, the warning can be performed in a graphical display and/or buzzing warning manner, or a voice broadcasting manner is used for warning that a person at the corresponding position needs to fasten the safety belt; if the information transmitted by the processing device 30 that the seat belts in all the seat positions in the vehicle are fastened is detected, the warning is not given. Therefore, the safety belt can remind people who do not fasten the safety belt in time, and safety is guaranteed to avoid punishment.
In an embodiment, as shown in fig. 3, the seatbelt monitoring system 100 further includes a vehicle speed monitoring device 80, wherein the vehicle speed monitoring device 80 is configured to collect a vehicle speed; the processing device 30 is further configured to adjust the reminding frequency of the reminding device 70 according to the vehicle speed. Specifically, a real-time vehicle speed signal of the vehicle may be acquired by a vehicle speed detection module in an ESP (Electronic Stability Program) or an ABS (antilock brake system) of the vehicle and provided to the processing device 30, and the processing device 30 may identify whether the vehicle is currently in a running state, for example, if the vehicle speed is not zero or greater than a certain value, the vehicle is in the running state, and if the safety belt is not fastened, the vehicle is in a high risk state, the prompting device 70 prompts and prompts at a high frequency to warn a person in a corresponding position to fasten the safety belt as soon as possible; if the vehicle speed is equal to zero, i.e., the vehicle is not running, the control prompting device 70 prompts at a slower frequency. Therefore, the alarm can not only play a role in warning, but also enable people to be aware of the danger in sense.
In some embodiments, the processing device 30 is further configured to obtain a power shift position of the vehicle and initiate monitoring of the seat belt upon detection of a power ON shift or initiation of an operating condition. Specifically, the vehicle body control device is a module for controlling the power-ON of the vehicle, and provides a power position signal of the vehicle, such as an OFF position, an ACC position, an ON position, and the like, to the processing device 30, and when the processing device 30 recognizes that the power position is the power ON position or the start operation state, the processing device starts to acquire the characteristic information of the sitting object, the stretch length of the seat belt, and the seat belt fastening state information to monitor the seat belt.
Taking a vehicle of 3 rows and 8 seats as an example, a driver is defined as a young male, and a safety belt is fastened; the secondary driving position is young women, and a safety belt is tied; the left seat position of the middle row is an old woman, and a safety belt is not tied; the middle row middle seat position is a child of underage, sitting on the safety child seat, is regarded as a seat belt is fastened, and the middle row right seat position is a male of old age, and is not fastened with the seat belt; the left seat of the back row is provided with a large teddy bear without a safety belt; the middle seat in the back row is a middle-aged female without a safety belt; the right seat position of the back row is a middle-aged male, and a safety belt is not tied. In addition, in the present embodiment, as shown in fig. 5, it is defined that one processing device 30 is disposed on the whole vehicle, and the characteristic information detecting device 10, the stretch length detecting device 20 and the fastening state detecting device 50 are disposed on the front, middle and rear rows of 8 seats, respectively, wherein the characteristic information detecting device 10 includes a weighing module 11, a body temperature module 12, a leg distance detecting sensor 01, a body length detecting sensor 02, a shoulder distance detecting sensor 03, a vital sign detecting sensor 04, and the like.
Specifically, when the driver (young male) starts the vehicle, the vehicle body control device 90 transmits a vehicle start operation state, and when the processing device 30 detects a power ON signal or a start operation state transmitted from the vehicle body control device 90, it first acquires whether or not the passenger is seated from the characteristic information detection device 10 of 8 seat positions, and since the teddy bear has a certain weight, it is regarded that the rear left seat position is seated, that is, the processing device 30 obtains seating signals for 8 seat positions, and at the same time, the characteristic information detection device 10 of each position transmits information such as the amount, body temperature, length (distance from shoulder to seat plane), volume, and leg length of the seated driver or passenger.
The processing device 30 compares a plurality of vital signs information such as weight, body temperature, shoulder distance, leg distance, body length and the like transmitted from the characteristic information detecting device 10 with the information base of the character model stored in advance to obtain the character types of passengers on 8 seats, wherein according to the rule, a large teddy bear is regarded as an article carried with a vehicle, a signal that whether a safety belt is tied or not is sent out at the seat position (the position of the left seat on the rear row) without judging whether the safety belt is tied is sent out, meanwhile, the position of the middle seat on the middle row is regarded as a special judgment processing because the child safety seat is tied, whether the safety belt is tied or not is judged by combining the definition of the child safety seat, the invention is not specified, so that the safety belt is regarded as being tied, and the other 6 seat positions are judged in.
The processing device 30 analyzes signals transmitted from the seatbelt fastening state detection devices 50 at 6 seat positions other than the middle-row middle seat position and the rear-row left seat position, and obtains a driver position and a passenger seat position where the seatbelt is fastened, and a middle-row left seat position, a middle-row right seat position, a rear-row middle seat position, and a rear-row right seat position where the seatbelt is not fastened, and the processing device 30 sends out a signal that the middle-row left seat position, the middle-row right seat position, the rear-row middle seat position, and the rear-row right seat position are not fastened with the seatbelt.
The processing device 30 finally analyzes the signals of the current position of the driver position and the current position of the passenger seat transmitted from the extension length detecting device 20 at the passenger seat position, the original extension length of the seat belt, and the like, and combines the character models of the passenger at the current position of the driver and the passenger at the passenger seat position to make a judgment according to the judgment criteria which needs to be defined in advance, and because the passenger at the driver position and the passenger seat position both fasten the seat belt as required and the extension length of the seat belt is within the error range allowed by the corresponding judgment criteria, the processing device 30 sends out a signal that the seat belt at the driver position and the passenger seat position is good.
In the analysis process, the processing device 30 will complete in a very short time, and when the vehicle is not running, that is, when the speed monitoring module such as ESP/ABS detects that the vehicle speed is 0, the processing device 30 sends a signal that the left seat position of the middle row, the right seat position of the middle row, the middle seat position of the rear row, and the right seat position of the rear row are not fastened with the seat belt in a relatively slow cycle; when the vehicle is running, i.e., the vehicle speed is not 0 or greater than a certain set value (the actual condition is defined for the running state of the vehicle according to the law), the processing device 30 determines that the vehicle is in the running state, and at this time, the processing device 30 sends a corresponding position seatbelt unfastened signal at a relatively fast cycle.
The reminding device 70, for example, an on-board instrument or other display device (mainly for displaying and warning whether the seat belts are fastened at each seat position in the vehicle) in the vehicle will receive the signal sent by the processing device 30 that the seat belts are not fastened at the left seat position, the right seat position, the middle seat position, and the right seat position in the rear row in the vehicle, and then the signal will be displayed graphically and buzzed for warning according to the signal sending period, and meanwhile, the personnel at the left seat position, the right seat position, the middle seat position, and the right seat position in the rear row in the vehicle will be warned that the safety belts need to be fastened by voice broadcasting.
The projection device 60, for example, a display device such as a HUD having a projection function, receives a signal from the processing device 30 that the seat belt is not fastened at the left seat position, the right seat position, the middle seat position, and the right seat position in the middle row in the vehicle, and displays monitoring information that the seat belt is not fastened at the left seat position, the right seat position, the middle seat position, and the right seat position in the rear row in the corresponding projection display information area of the front windshield.
When a vehicle passes through a camera arranged by a traffic department, if the safety belts are not fastened at the position of the left seat in the middle row, the position of the right seat in the middle row, the position of the middle seat in the middle row and the position of the right seat in the rear row, the monitoring information that the safety belts at the above four positions in the vehicle are not fastened is captured by the camera for traffic monitoring from the front windshield of the vehicle, so that the behavior that the vehicle violates the traffic driving regulations is recorded, and the method is more efficient and accurate.
In summary, the safety belt monitoring system 100 according to the embodiment of the present invention determines the character models of various passengers through a certain standard and an identification algorithm, determines whether the safety belt is locked in the buckle, and performs a comprehensive analysis by using the actual extension distance of the safety belt and the corresponding standard, so as to effectively determine whether the driver and the passenger actually fasten the safety belt, thereby preventing some people from making a chance to fasten the safety belt or preventing the system from misjudging that the safety belt is not fastened when the seat places an object. In addition, for the problem that the in-vehicle seat belt monitoring and the out-vehicle traffic monitoring device cannot be well combined and utilized, based on the seat belt monitoring system 100 of the embodiment, the original traffic department monitoring camera can keep the image recognition mode, on the basis, a camera is set, and the camera recognizes the seat belt monitoring information provided by the projection device 60, such as a HUD and other display devices with the projection function, on the front windshield glass, so that whether the seat belts of all seats in each running vehicle are tied or not can be effectively monitored, and the individual privacy of drivers and passengers is not violated.
