Fig. 1 is a flowchart illustrating a vehicle rear seat belt presentation method according to an exemplary embodiment, and as shown in fig. 1, the vehicle rear seat belt presentation method includes the steps of:

step S100: acquiring current state information of a target vehicle, wherein the current state information comprises back door state information and wheel speed information;

in the step, it should be noted that the method is used for prompting the wearing of the rear seat belt of the vehicle, after the whole vehicle of the target vehicle is powered on, the rear door state information is acquired through the sensors in the door structures at the two sides of the rear seat of the target vehicle, wherein the rear door state information comprises the rear door opening and closing condition information and the opening and closing angle information at the two sides of the rear seat of the target vehicle, in one implementation way, the opening and closing condition of the rear door can be detected through the photoelectric sensor, when the rear door is opened or closed, the photoelectric sensor detects the locking condition between the lock catch of the door and the lock tongue arranged in the vehicle frame, the rear door opening and closing are monitored, the data acquisition is realized, and after the data acquisition of the photoelectric sensor, the data transmission to the air bag control unit RCM is realized,

It can be appreciated that, in order to ensure the ordering of the data processing, the photoelectric sensor may be configured to acquire the back door status information of the target vehicle every first preset time, for example, the back door status information is performed every 10 seconds, and of course, the time period of the first preset time may be preset to other values, which are not limited herein, but in order to ensure the validity of the collected data, the data interval is less than one minute;

meanwhile, after the whole target vehicle is electrified, a wheel speed sensor preset on the wheels of the target vehicle also acquires the wheel speed of the vehicle in real time, the wheel speed sensor also transmits the acquired wheel speed information data to an air bag control unit RCM, in order to ensure that the acquired data are orderly processed, the wheel speed sensor acquires the wheel speed information of the target vehicle every second preset time, for example, the wheel speed information acquisition is carried out every 20 seconds, the acquisition time interval can be determined according to the actual situation, the limitation is not made, the wheel speed information comprises the wheel speed actual value corresponding to each wheel, and the air bag control unit RCM carries out data processing after receiving the back door state information and the wheel speed information;

It should be further understood that the method steps may be applied to five or more vehicles, for example, for a commercial minibus with double-row rear seats, the method steps may also be performed by collecting rear door status information and wheel speed information, and then performing subsequent method steps.

Step S200: judging whether the back door state information of the target vehicle changes and whether the wheel speed is greater than a first preset threshold value according to the current state information;

in the step, the central controller of the target vehicle performs data processing according to the back door state information acquired by the photoelectric sensor and the wheel speed information acquired by the wheel speed sensor, specifically, in order to improve the accuracy of judgment, the memory temporarily pre-stores the back door state information acquired by the photoelectric sensor at intervals of preset time, for example, pre-stores data acquired in ten minutes, when ten minutes later, the data are refreshed, the central controller analyzes and processes the data transmitted by the photoelectric sensor each time, and if the back door state information acquired by the front and back two times is judged to be different in ten minutes later, the difference can be understood as that the back doors are opened and closed;

Similarly, in order to improve the effectiveness and accuracy of the judgment, the memory temporarily pre-stores the wheel speed information acquired by the wheel speed sensor for a period of time, and when the wheel speed sensor transmits the acquired data to the central controller each time, the central controller judges and analyzes whether the wheel speed is greater than a first preset threshold value, wherein the first preset threshold value can be determined according to the actual vehicle condition, for example, in one embodiment, the central controller judges whether the wheel speed is greater than 300rpm according to the wheel speed data value in the wheel speed information;

of course, it can be understood that, after the whole vehicle is powered on, if the back door state information of the target vehicle is not changed or the wheel speed of the target vehicle is smaller than the first preset threshold value, at this time, the wheel speed sensor and the photoelectric sensor do not stop monitoring and collecting data, and still can continuously acquire the back door state information and the wheel speed information of the target vehicle, and meanwhile, the memory can format and refresh the data temporarily stored in a period of time.

Step S300: continuously acquiring connection condition information of a safety belt lock catch and a safety belt lock tongue and furling amount information of the safety belt if the state information of a rear door of the target vehicle changes and the wheel speed is larger than a first preset threshold value;

In this step, after the central controller of the target vehicle determines that the rear door state information changes and the wheel speed is greater than a first preset threshold, it may be primarily determined that there is a possibility that a user is on a rear seat of the target vehicle, while the target vehicle is traveling, at this time, the central controller may generate a prompt control instruction and transmit the prompt control instruction to a combination meter of the target vehicle, where the combination meter executes a first safety prompt policy according to the prompt control instruction, and the first safety prompt policy may prompt the user with graphic information through the combination meter to remind the user that the user is still riding other users on the rear seat of the target vehicle and prompt the user of the rear seat to tie a safety belt, so that the primary rear seat belt uses the prompt setting to avoid causing an error prompt;

of course, for the graphic information prompt of the combination instrument, the user can manually close the prompt after knowing, and of course, the display time limit can be carried out on the graphic information prompt displayed on the combination instrument, and when the display time limit is exceeded, the graphic information prompt is automatically ended;

in order to further ensure whether the target vehicle rear seat user is correctly fastened with the seat belt, in some embodiments, the seat belt of each position of the target vehicle rear seat may be marked, and meanwhile, connection condition information of the seat belt lock and the seat belt lock tongue may be collected and transmitted through a lock catch sensor preset in each seat belt lock catch, where the connection condition information includes a connection state parameter of the seat belt lock catch and the seat belt lock tongue, and a seat position parameter corresponding to the seat belt lock catch and the seat belt lock tongue, and the lock catch sensor may specifically be a photoelectric sensor;

In order to avoid the existence of a light mind of the user and ensure the riding safety of the user, in some embodiments, the rolling amount information of the safety belt can be collected and transmitted through a pulse sensor preset on each safety belt rolling barrel, wherein the rolling amount information comprises a corresponding safety belt rolling length state parameter and a seat position parameter corresponding to the safety belt lock catch and the safety belt lock tongue;

it can be understood that the above-mentioned connection condition information of the seat belt buckle and the seat belt lock tongue collected by the buckle sensor preset in each seat belt buckle and the seat belt volume information collected by the pulse sensor preset in each seat belt winding drum are transmitted to the central controller of the target vehicle, and the central controller processes the collected information;

step S400: judging whether the safety belt lock catch and the safety belt lock tongue are normally connected and whether the rolling amount of the safety belt is larger than a second preset threshold value according to the collected connection condition information of the safety belt lock catch and the safety belt lock tongue and the rolling amount information of the safety belt;

in this step, the central controller of the target vehicle, according to the collected connection condition information of the safety belt lock catch and the safety belt lock tongue, needs to be explained that when the connection condition of the safety belt lock catch and the safety belt lock tongue is collected, if the safety belt lock catch and the safety belt lock tongue are locked and unlocked, the photoelectric signals transmitted to the central controller are generated, so that the central controller judges the connection condition of the safety belt lock catch and the safety belt lock tongue according to the transmitted photoelectric signals, if the safety belt lock catch and the safety belt lock tongue are judged to be locked, the safety belt lock catch and the safety belt lock tongue are indicated to be in normal connection, and if the safety belt lock catch and the safety belt lock tongue are judged to be unlocked, the safety belt lock catch and the safety belt lock tongue are indicated to be not in normal connection;

Further, in order to ensure the accuracy of the belt prompt, the central controller of the target vehicle further analyzes and judges the belt winding amount information acquired by the pulse sensor preset in each belt winding drum, wherein the belt winding amount information comprises the winding length of the belt, if the belt winding length is judged to be greater than a second preset threshold value, and the belt lock catch and the belt lock tongue are locked, the belt is normally taken by a user of the rear seat of the surface target vehicle, and it can be understood that the second preset threshold value refers to the winding length judgment value of the belt, the value needs to be referred to by referring to the structural characteristics of the human body, and particularly, the value can be obtained through multiple experiments, for example, 50cm or 40cm;

step S500: if the safety belt lock catch and the safety belt lock tongue are not normally connected or the rolling amount of the safety belt is smaller than a second preset threshold value, executing a second safety prompt strategy;

in the step, a central controller of a target vehicle judges the connection condition of a transmitted safety belt lock catch and a safety belt lock tongue or the rolling amount of the safety belt, if the judging result is that the safety belt lock catch and the safety belt lock tongue are not normally connected or the rolling amount of the safety belt is smaller than a second preset threshold value, a user of a rear seat of the surface target vehicle does not correctly tie the safety belt, and at the moment, the central controller generates another prompting control instruction and transmits the prompting control instruction to a combination instrument to execute a second safety prompting strategy;

After the connection condition of the safety belt lock catch and the safety belt lock tongue at the corresponding position is acquired, the lock catch sensor arranged in the safety belt lock tongue also comprises the number of the corresponding position of the rear seat, so that after the central controller receives the data, the safety belt lock catch and the safety belt lock tongue at the specific position of the rear seat can be accurately judged to be normally connected, the rolling amount of the safety belt is larger than a second preset threshold value, another prompting control instruction is generated and transmitted to the combination instrument to execute a second safety prompting strategy, wherein the second safety prompting strategy comprises graphic information prompting and voice broadcasting prompting of the unbelted safety belt at the position through the combination instrument of the target vehicle;

meanwhile, if the central controller judges that the safety belt lock catch corresponding to a certain position of the rear seat of the target vehicle is normally connected with the safety belt lock tongue and the rolling amount of the safety belt is larger than a second preset threshold value, a third safety prompt strategy is executed, wherein the third safety prompt strategy comprises graphic information prompt through a combination instrument of the target vehicle.

It can be understood that the second safety prompting strategy prompts that the seat belt is not correctly fastened at a certain position of the rear seat, and the third safety prompting strategy prompts that the seat belt is correctly fastened at a certain position of the rear seat, so that a user can more accurately know the specific wearing condition of the seat belt of the rear seat of the target vehicle;

In the method, whether the rear door state information and the wheel speed information of the target vehicle are continuously acquired, whether the rear door state information of the target vehicle is changed or not and whether the wheel speed is larger than a first preset threshold value or not are judged, if the rear door state information of the target vehicle is changed or the wheel speed is larger than the first preset threshold value, the vehicle is controlled to execute a first safety prompt strategy, whether a user exists in a rear seat of the vehicle or not and whether the user is effectively prompted to wear a safety belt is realized in the process, meanwhile, the connection condition information of a safety belt lock catch and a safety belt lock tongue at each position of the rear seat and the rolling amount information of the safety belt are continuously acquired through a sensor, and according to the judgment that if the safety belt lock catch and the safety belt lock tongue are not normally connected or the rolling amount of the safety belt is smaller than a second preset threshold value, the second safety prompt strategy is executed, and comprises image-text information prompt and voice information prompt of the safety belt which are not worn correctly at the corresponding position.

The braking system 635 is used to control deceleration of the vehicle 600. The braking system 635 may use friction to slow the wheels 644. In some embodiments, the braking system 635 may convert kinetic energy of the wheels 644 into electrical current. The braking system 635 may take other forms to slow the rotational speed of the wheels 644 to control the speed of the vehicle 600.

The drive system 640 may include components that provide powered movement of the vehicle 600. In one embodiment, the drive system 640 may include an engine 641, an energy source 642, a transmission 643, and wheels 644. The engine 641 may be an internal combustion engine, an electric motor, an air compression engine, or other types of engine combinations, such as a hybrid engine of a gasoline engine and an electric motor, or a hybrid engine of an internal combustion engine and an air compression engine. The engine 641 converts the energy source 642 into mechanical energy.

Examples of energy sources 642 include gasoline, diesel, other petroleum-based fuels, propane, other compressed gas-based fuels, ethanol, solar panels, batteries, and other sources of electricity. The energy source 642 may also provide energy to other systems of the vehicle 600.

The transmission 643 may transfer mechanical power from the engine 641 to wheels 644. The transmission 643 may include a gearbox, a differential, and a driveshaft. In one embodiment, the transmission 643 may also include other devices, such as a clutch. Wherein the drive shaft may include one or more axles that may be coupled to one or more wheels 644.

Some or all of the functions of the vehicle 600 are controlled by the computing platform 650. The computing platform 650 may include at least one processor 651, and the processor 651 may execute instructions 653 stored in a non-transitory computer-readable medium, such as memory 652. In some embodiments, computing platform 650 may also be a plurality of computing devices that control individual components or subsystems of vehicle 600 in a distributed manner.

The processor 651 may be any conventional processor, such as a commercially available CPU. Alternatively, the processor 651 may also include, for example, an image processor (Graphic Process Unit, GPU), a field programmable gate array (Field Programmable Gate Array, FPGA), a System On Chip (SOC), an application specific integrated Chip (Application Specific Integrated Circuit, ASIC), or a combination thereof. Although FIG. 3 functionally illustrates a processor, memory, and other elements of a computer in the same block, it will be understood by those of ordinary skill in the art that the processor, computer, or memory may in fact comprise multiple processors, computers, or memories that may or may not be stored within the same physical housing. For example, the memory may be a hard disk drive or other storage medium located in a different housing than the computer. Thus, references to a processor or computer will be understood to include references to a collection of processors or computers or memories that may or may not operate in parallel. Rather than using a single processor to perform the steps described herein, some components, such as the steering component and the retarding component, may each have their own processor that performs only calculations related to the component-specific functions.

In an embodiment of the present disclosure, the processor 651 may perform the vehicle rear seat belt reminder method described above.

In various aspects described herein, the processor 651 can be located remotely from and in wireless communication with the vehicle. In other aspects, some of the processes described herein are performed on a processor disposed within the vehicle and others are performed by a remote processor, including taking the necessary steps to perform a single maneuver.

In some embodiments, fourth memory 652 may contain instructions 653 (e.g., program logic), which instructions 653 may be executed by fourth processor 651 to perform various functions of vehicle 600. Memory 652 may also contain additional instructions, including instructions to send data to, receive data from, interact with, and/or control one or more of infotainment system 610, perception system 620, decision control system 630, drive system 640.

In addition to instructions 653, memory 652 may store data such as road maps, route information, vehicle location, direction, speed, and other such vehicle data, as well as other information. Such information may be used by the vehicle 600 and the computing platform 650 during operation of the vehicle 600 in autonomous, semi-autonomous, and/or manual modes.

The computing platform 650 may control the functions of the vehicle 600 based on inputs received from various subsystems (e.g., the drive system 640, the perception system 620, and the decision control system 630). For example, computing platform 650 may utilize input from decision control system 630 in order to control steering system 633 to avoid obstacles detected by perception system 620. In some embodiments, computing platform 650 is operable to provide control over many aspects of vehicle 600 and its subsystems.

Alternatively, one or more of these components may be mounted separately from or associated with vehicle 600. For example, the memory 652 may exist partially or completely separate from the vehicle 600. The above components may be communicatively coupled together in a wired and/or wireless manner.

Alternatively, the above components are only an example, and in practical applications, components in the above modules may be added or deleted according to actual needs, and fig. 3 should not be construed as limiting the embodiments of the present disclosure.

Alternatively, the vehicle 600 or a sensing and computing device associated with the vehicle 600 (e.g., computing system 631, computing platform 650) may predict the behavior of the identified object based on the characteristics of the identified object and the state of the surrounding environment (e.g., traffic, rain, ice on a road, etc.). Alternatively, each identified object depends on each other's behavior, so all of the identified objects can also be considered together to predict the behavior of a single identified object. The vehicle 600 is able to adjust its speed based on the predicted behavior of the identified object. In other words, the autonomous car is able to determine what steady state the vehicle will need to adjust to (e.g., accelerate, decelerate, or stop) based on the predicted behavior of the object. In this process, other factors may also be considered to determine the speed of the vehicle 600, such as the lateral position of the vehicle 600 in the road on which it is traveling, the curvature of the road, the proximity of static and dynamic objects, and so forth.

In addition to providing instructions to adjust the speed of the autonomous vehicle, the computing device may also provide instructions to modify the steering angle of the vehicle 600 so that the autonomous vehicle follows a given trajectory and/or maintains safe lateral and longitudinal distances from objects in the vicinity of the autonomous vehicle (e.g., vehicles in adjacent lanes on a roadway).

Correspondingly, the embodiment of the application also provides a readable storage medium, wherein the readable storage medium stores instructions which, when run on a computer, cause the computer to execute the steps of the vehicle rear seat belt prompting method described in the above embodiment.
