Description
Technical Field
The invention belongs to the technical field of vehicle safety, and particularly relates to a system and a method for reminding a safe sitting posture in a vehicle.
Background
In modern society, automobiles have become one of the most important vehicles, but the riding safety is often not paid enough attention. Some passengers sometimes adopt a half-lying or flat-lying posture during riding for comfort, and some minors with insufficient height can ride a car without a safety seat, which all cause serious safety hazards. In the event of a vehicle collision, an incorrect sitting posture may cause injury to the passenger, or throw the passenger out of the vehicle, or even cause the passenger to lose life.
It should be noted that the airbag and the seat belt of the car are designed within a certain range based on the sitting posture of the passenger and the driver, and if the sitting posture of the passenger or the driver is deviated greatly, the airbag and the seat belt may not function, and even may function in the opposite direction, and injure the passenger or the driver. For example, a minor with insufficient height sits at a copilot, a driver or a passenger at the copilot twists to turn around to chat with a back-row passenger, the driver takes the contents in the glove box at the copilot with the hand during driving, and the back-row passenger falls down to sleep at a back seat to clamp the safety belt to the neck, which can cause the safety airbag and the safety belt to be out of action or even play an opposite role in a traffic accident.
In the prior art, a method for detecting sitting posture safety of passengers in a vehicle comprises the steps of obtaining the running speed of the vehicle; when the running speed of the vehicle is greater than or equal to a preset value, the sitting posture of a passenger on a non-driving position is obtained; comparing the sitting posture of the passenger in the non-driving position with a preset dangerous sitting posture; and when the sitting posture of the passenger in the non-driving position is the same as the preset dangerous sitting posture, sending dangerous sitting posture reminding information.
It can be seen that the above-mentioned method for detecting the sitting posture of the passenger in the vehicle does not take into account the situation that the minor who is short in height takes the vehicle without the safety seat, and does not take into account the problem of the safety action range of the safety airbag and the safety belt of the vehicle. In addition, by presetting various dangerous sitting postures in the system and comparing the dangerous sitting postures with the obtained sitting postures of the passengers one by one, a large amount of data needs to be prestored and collected, and the calculation process is also complicated.

Detailed Description
The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. This description is given by way of example only and is not intended to limit the present invention.
Referring to fig. 1, an exemplary embodiment of the in-vehicle safe sitting posture reminding system of the present invention comprises an image recognition module 101, a control module 102 and an alarm module 103, wherein: the image recognition module 101 is configured to recognize a positional relationship between a passenger and/or a driver in a vehicle and a seat, and transmit generated positional relationship information to the control module 102; the control module 102 is configured to compare the received position relationship information with a pre-stored safety action range of an airbag and a seat belt, so as to determine whether the position relationship information deviates from the safety action range of the airbag and the seat belt; and the alarm module 103 is configured to issue a safety alarm under the control of the control module 102 when the positional relationship information deviates from the safety action range of the airbag and the seat belt. In fact, the image recognition module 101 and the alarm module 103 may both be controlled by the control module 102, and the control module 102 may be included in a vehicle central control system.
Specifically, the positional relationship between the passenger and/or the driver and the seat identified by the image identification module 101 includes: the distance H between the head of the passenger and/or driver and the top of the seat, and/or the distance W between the body side of the passenger and/or driver and the respective side of the seat, and/or the distance D between the back of the passenger and/or driver and the seat.
For example, when an underheight minor is riding in a car without a safety seat, the minor's head will obviously have a greater distance from the top of its seat than a normal passenger; this is also true for passengers of normal height who assume a semi-reclined or flat-reclined position. Also for example, when a driver is holding the contents of the glove box in a co-driver position with his hands, the distance between the left side of his body and the left side of his seat can be significantly greater than in a normal sitting position; when the driver or the passenger in the passenger compartment turns around and chats about a large percentage of the passengers in the rear row, the distance between the back and the seat is also significantly greater than that in the normal sitting position. Therefore, it is possible to simply determine whether a potential safety hazard exists in the sitting posture of the passenger and/or the driver by measuring the distances.
The airbag and the seat belt of the automobile are designed within a certain range based on the sitting posture of the passenger and the driver, and thus have a certain safety range. For example, the safety action ranges of airbags and safety belts include a high safety range, a wide safety range and a deep safety range with respect to the upper body of a passenger and/or a driver, wherein the high safety range is measured in the vertical direction of the automobile, the wide safety range is measured in the left-right direction of the automobile, and the deep safety range is measured in the front-rear direction of the automobile. When the upper body of the passenger and/or driver is within this safety-functioning range, it means that the airbag and the safety belt can function effectively. The present invention takes this point into consideration, and organically combines the positional relationship information of the passenger and/or the driver with the seat obtained by the image recognition module with the safety action ranges of the airbag and the seat belt, specifically, compares the two, and if at least one of the height position, the width position, and the depth position of the upper body of the passenger and/or the driver on the seat exceeds the above-mentioned height safety range, width safety range, or depth safety range of the airbag and the seat belt, respectively, it can be determined that the passenger and/or the driver is in a dangerous sitting posture and a safety alarm needs to be issued.
The in-vehicle safe sitting posture reminding system only works when the vehicle runs, so that unnecessary alarms are prevented from being sent out when people in the vehicle have a rest in a parking state. Specifically, under the control of the control module, the image recognition module recognizes the positional relationship of the passenger and/or the driver with the seat only at certain time intervals while the vehicle is traveling. For example, the time interval may be 5 seconds, or may be shorter or longer. When driving at night or in a section where road conditions are dangerous, the time interval may be set to be short; and when driving in daytime or driving in a section with good road conditions, the time interval can be set to be longer.
The image recognition module in the invention can be an intelligent recognition camera, which can be arranged on the roof part above the seats of each passenger and driver, or can be arranged on other suitable parts. For example, the camera may be provided on an interior trim panel on the side of the seat. It is also contemplated that multiple cameras may be provided at different locations for a single seat, thereby obtaining more comprehensive seating information, if a camera provided at only one location is insufficient to identify the full positional relationship of the passenger and/or driver to the seat. All of these cameras communicate with the control module in a wired or wireless manner.
According to the present invention, when the control module determines that a passenger and/or a driver is in a dangerous sitting position and needs to give a safety alarm, it may notify the alarm module to give an alarm by wire or wirelessly. The alarm module may be an instrument display screen located in front of the driver, on which it can be shown which seat passengers and/or driver are currently sitting too far out of position, with safety risks. The alarm module can also comprise a buzzer at the same time so as to better remind people.
The working flow of the in-vehicle safe sitting posture reminding method of the invention is exemplarily described below with reference to fig. 2.
First, in step S1, the positional relationship between the passenger and/or the driver and the seat is identified and the positional relationship information is generated. For example, the method for intelligently measuring and calculating the position relationship between a seated passenger and/or a driver and a seat thereof through a camera specifically comprises the following steps: the distance H between the head of the passenger and/or driver and the top of the seat, and/or the distance W between the body side of the passenger and/or driver and the respective side of the seat, and/or the distance D between the back of the passenger and/or driver and the seat. The opening/closing and the operation of the camera are controlled by the control module and are in wired or wireless communication with the control module. And after the position relation information is generated, the camera sends the information to the control module.
In the following step S2, the control module compares the received positional relationship information with the safety action ranges of the pre-stored airbag and seat belt, and determines whether the positional relationship information deviates from the safety action ranges of the pre-stored airbag and seat belt. If the judgment result is yes, the control module informs the alarm module to alarm in a wired or wireless mode, and goes to the following step S3; if the determination result is "no", it returns to step S1, i.e., the positional relationship between the passenger and/or the driver and the seat is continuously recognized by the camera at certain time intervals.
The control module has previously stored the safety action ranges of the airbags and safety belts, which include a height safety range, a width safety range and a depth safety range with respect to the upper body of the passenger and/or driver, wherein the height safety range is measured in the vertical direction of the vehicle, the width safety range is measured in the left-right direction of the vehicle, and the depth safety range is measured in the front-rear direction of the vehicle. In step S2, the step of determining whether the positional relationship information deviates from the safety action ranges of the pre-stored airbag and the seat belt specifically includes: it is determined that the positional relationship information deviates from the pre-stored safety action range of the airbag and the seatbelt if at least one of a distance H between the head of the passenger and/or the driver and the top of the seat, a distance W between the body side of the passenger and/or the driver and the corresponding side of the seat, and a distance D between the back of the passenger and/or the driver and the seat exceeds the corresponding height safety range, width safety range, or depth safety range of the airbag and the seatbelt.
In the next step S3, the alarm module receives the alarm command sent by the control module and issues a security alarm through the in-vehicle display screen and/or the buzzer. For example, there may be an alarm sounding in the vehicle and a safety risk of displaying on the dashboard screen in front of the driver which seat passenger and/or driver is currently sitting out of position too much.
After step S3, the process continues back to step S1 for continuous monitoring of the sitting posture of the passenger and/or driver in the vehicle.
The invention can avoid the safety accidents caused by incorrect sitting postures of passengers and/or drivers in a simple and effective mode, avoid the dangerous situation that minors with insufficient height take the automobile without a safety seat, and effectively improve the driving and riding safety.
Although the present invention has been described with reference to the preferred embodiments, it is not to be limited thereto. Various changes and modifications within the spirit and scope of the present invention will become apparent to those skilled in the art from this disclosure, and it is intended that the scope of the present invention be defined by the appended claims.
