Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments herein without making any creative effort, shall fall within the scope of protection.

It should be noted that the terms "first," "second," and the like in the description and claims herein and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments herein described are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, apparatus, article, or device that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or device.

Vehicles such as bicycles, electric vehicles and motorcycles provide convenience for people to go out, and various illegal driving problems also occur, so that traffic accidents are frequent. In the prior art, the problems of low monitoring degree, low coverage rate, poor timeliness of handling the illegal driving behaviors and the like exist in the monitoring management of the illegal driving behaviors of the vehicles.

In order to solve the above problems, embodiments herein provide a dangerous driving monitoring method, apparatus, system and storage medium, which can improve monitoring strength for dangerous driving of vehicles such as the above bicycles and electric vehicles, improve safety awareness of drivers, reduce or even stop traffic accidents from the source, and greatly ensure personal safety and property safety of users. The method is based on a vehicle provided by the embodiment, as shown in fig. 1, the vehicle comprises a central controller 10 and a pressure sensor 30;

the central controller 10 is connected to the pressure sensor 30 to control the vehicle according to the load data detected by the pressure sensor 30.

The pressure sensor 30 is configured to acquire load data of the vehicle and send the acquired load data to the central controller 10. Specifically, the pressure sensor 30 can convert analog information obtained by physical deformation into a data signal, further convert the data signal into load data, and send the load data to the central controller 10.

The pressure sensors 30 include a first pressure sensor, a second pressure sensor, and a third pressure sensor;

the first pressure sensor is arranged at a basket 70 of the vehicle, and the basket 70 is positioned in front of the vehicle head and used for placing articles;

the second pressure sensor is arranged at a shock absorber and/or at a fork 50 and/or at a seat cushion 60 of the vehicle. The shock absorbers comprise a front shock absorber 41 and a rear shock absorber 42, the front shock absorber 41 is located between the head of the electric vehicle and front wheels, and the rear shock absorber 42 is located between the seat cushion 60 and rear wheels. The second pressure sensor may be provided at the front shock absorber 41 and/or the rear shock absorber 42.

The third pressure sensor is arranged at a handlebar of the vehicle, which handlebar comprises an accelerator grip 22 and the brake grip 23.

When the vehicle is a bicycle, the central controller 10 may decelerate or stop the vehicle by the brakes (specifically, brake pads) of the vehicle.

As shown in fig. 2, when the vehicle is an electric vehicle or an electric motorcycle, the vehicle further includes a motor controller 20, and the motor controller 20 is connected to a battery 21, an acceleration handle 22, a brake handle 23 and a motor 24, and is configured to control output power of the motor according to information of electric quantity of the battery 21, information of acceleration of the acceleration handle 22 and information of braking of the brake handle 23, so as to control a vehicle speed. The battery 21 is used for providing a power source, and the motor 24 is used for converting the electric energy provided by the battery 21 into mechanical energy to drive the vehicle to run. When the vehicle is an electric vehicle, an electric motorcycle, or other assisted vehicle, the central controller 10 can not only control the brake pads to tightly hold the wheels to perform the braking and decelerating functions, but also control the motor controller 20 to reduce the power of the motor 24 to perform the decelerating and stopping functions.

In the vehicle provided in the embodiment of the present specification, the central controller can acquire vehicle load data according to the pressure sensor to control the vehicle, and when it is determined that the vehicle is empty or overloaded or carries a person in violation of load according to the load data, the central controller controls the vehicle to decelerate or stop operating in a brake control manner or in a brake and motor controller manner, so as to avoid occurrence of the dangerous driving behavior and avoid personal injury and property loss caused by the dangerous behavior, and a specific control method of the central controller will be described in detail later.

In the embodiment of the specification, the no-load is generally specific to the electric bicycle, and means that when a user does not get on the electric bicycle, the acceleration handle of the electric bicycle is triggered by mistake, and the electric bicycle is easy to flee or fly out, and may hurt the user; overload means that the load on the vehicle exceeds the rated weight, and at the moment, the vehicle is heavily loaded, so that inertia greatly influences the sensitivity of braking, danger easily occurs, and the service life of the vehicle is lost; the illegal carrier is specified in the relevant regulations of road safety regulations: the bicycle and the electric bicycle are only required to carry one person under 12 years old, and other carrying situations belong to the phenomenon of illegal carrying of people. The central controller 10 is also connected with a horn 11 and an instrument 12, and when no-load, overload, illegal man-carrying and other dangerous driving behaviors are judged, a warning sound can be sent out through the horn, and a user can be reminded in a normally-on or flickering mode through a corresponding indicator lamp on the instrument.

In some feasible embodiments, the central controller 10 may also be connected to a mobile terminal such as a mobile phone and a tablet, and a vehicle management and traffic safety management server through wireless communication, so as to send the operation data of the entire vehicle, the dangerous driving behavior data of the driver, and the like to a user, a vehicle management part, a traffic safety supervision department, and the like, so that the user and the vehicle management department can grasp the operation state of the entire vehicle, analyze a possible or occurred fault problem, and maintain and replace a possible or occurred component, thereby ensuring the vehicle safety; the dangerous driving behavior data is sent to the user and supervision departments such as traffic safety management and the like to remind the user to improve the safety travel consciousness and standardize the riding behavior of the user; and the traffic safety monitoring part can also punish dangerous driving behaviors of the user.

Fig. 3 is a schematic diagram of steps of a dangerous driving monitoring method provided in the embodiments herein, and the present specification provides the method operation steps as described in the embodiments or the flowchart, but more or less operation steps may be included based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. When an actual system or apparatus product executes, it can execute sequentially or in parallel according to the method shown in the embodiment or the figures. As shown in fig. 3, the method may include:

s310: acquiring first load data of a vehicle and second load data after a preset time interval;

the first load data and the second load data are pieces of measured weight information other than the weight of the vehicle itself. The first load data and the second load data can be obtained through a second pressure sensor, the second pressure sensor is arranged at a shock absorber and/or a bottom fork 50 and/or a cushion 60 of the vehicle, namely the second pressure sensor can be arranged to obtain the load data of the vehicle at regular time or in real time and send the obtained load data to the central controller. The vehicle refers to a vehicle for a single adult to ride, including a bicycle, an electric vehicle, an electric motorcycle and the like. For example, in this embodiment, the preset time may be set to 10s, and the central controller will obtain the load data of the vehicle every 10 s.

S320: calculating a difference between the second load data and the first load data;

specifically, when the first load data is not zero, calculating a difference value between load data acquired twice in a neighboring manner; and when the first load data is zero, taking the second load data as the first load data, acquiring new second load data after a preset time interval, and repeating the judgment process.

S330: comparing the difference value with a preset first load threshold value;

the first weight threshold is about the weight of an adult, and may be set to 45kg, 50kg, etc., for example. It should be noted that the difference is obtained by subtracting the first load data from the second load data, so as to determine whether the load of the vehicle increases after a preset time interval according to the difference.

S340: and when the difference value is larger than or equal to the first load threshold value, controlling the vehicle to decelerate.

In the dangerous driving monitoring method provided in the embodiment of the present specification, whether the load of the vehicle increases is determined according to the first load data and the second load data, and if the load increase amount (i.e., the difference) of the vehicle reaches a first load threshold (i.e., the weight of an adult), it is determined that dangerous driving behavior with an illegal carrier occurs, and the vehicle is controlled to slow down until the vehicle stops. In the actual use scene of the vehicle, the illegal man-carrying phenomenon is often prohibited, mainly because the person who sits at the rear side can get off at will to escape the supervision when meeting a camera or a traffic police. In the embodiment of the specification, the phenomenon of illegal man carrying can be judged at the moment of increasing the load, so that dangerous driving behaviors of illegal man carrying can be prevented in time.

In an actual application scenario, there may be a situation that a user places a cargo on a vehicle before getting on the vehicle, and in this situation, the condition that the first load data is not zero and the difference is greater than or equal to the first load threshold is also satisfied, so the above determination method has an inaccurate problem.

In the embodiment of the present specification, preferably, step S340: controlling the vehicle to decelerate when the difference is greater than or equal to the first load threshold, further comprising:

comparing the first load data to the first load threshold;

and when the first load data and the difference value are both larger than the first load threshold value, sending violation manned reminding.

When the first load data and the difference value are both larger than the first load threshold value, it can be judged that one person takes the vehicle after the other person takes the vehicle, namely, the phenomenon of illegal person carrying occurs, at the moment, the illegal person carrying reminder is sent, so that the phenomenon of illegal person carrying can be timely found and prevented from the source, the effect of improving the safe driving consciousness of the user is achieved, traffic accidents caused by the phenomenon are avoided, the personal safety and the property safety of the user are guaranteed, and the accuracy of judging the phenomenon of illegal person carrying is also improved.

In the embodiment of the specification, whether the phenomenon of illegal man carrying exists is judged through the load data acquired by the second pressure sensor, so that the monitoring of dangerous driving behaviors such as illegal man carrying is realized, and compared with a method of face recognition in the prior art, the cost is greatly reduced.

Further, when the first load data and the difference are both greater than or equal to the first load threshold, controlling the vehicle to decelerate, further comprising:

acquiring speed information of the vehicle;

the speed information may include an average speed or a maximum value of the speed of the vehicle over a period of time, an instantaneous speed at a certain moment, a change range of the speed over a period of time, a change rate, and the like.

Comparing the speed information with a preset first speed threshold value;

for example, the average speed during the period from the first load data to the second load data may be compared with a preset first speed threshold; the first speed threshold value may be set to a value of zero, although it may also be set to other values, such as 10-15km/h, etc., which is approximately the speed at which the person walks. The speed information may be obtained by a speed sensor.

When the speed information is larger than or equal to the first speed threshold value, sending an illegal manned reminder and controlling the vehicle to decelerate until the vehicle stops;

when the average speed is larger than or equal to the first speed threshold value, the vehicle can be judged to be in a running state, at the moment, a mode of controlling the vehicle to decelerate is adopted, so that the vehicle is gradually decelerated until the vehicle stops, the illegal manned behavior of a user is prevented, and meanwhile, the situation that the riding personnel fall down due to the fact that the vehicle suddenly stops moving forward is avoided. Specifically, when the vehicle is a bicycle, the central controller can control the brake pads to lock the tires, and the resistance of the vehicle in forward running is increased, so that the vehicle is decelerated until the vehicle stops; when the vehicle is an electric power-assisted vehicle such as an electric vehicle, an electric motorcycle and the like, the central controller can control the motor controller to reduce the output probability of the motor besides increasing the friction force through braking.

And when the speed information is smaller than the first speed threshold value, controlling the vehicle not to start.

When the average speed is less than the first speed threshold, it may be that two people are riding on the vehicle or that a weight is placed on the vehicle. At this moment, because there is not dangerous driving problem in fact in the vehicle state of not going, but the life of vehicle can be seriously influenced to overweight load, consequently, can make the vehicle unable start under this prerequisite to stop the transmission of the manned phenomenon of violating the regulations from the source. In addition, a violation manned reminder can be sent to remind rear passengers to get off or remind users to reduce the load.

As shown in fig. 4, in the embodiment of the present specification, after acquiring the first load data or after acquiring the first load data and the second load data, the method further includes:

s410: comparing each load data with a preset second load threshold, wherein the second load threshold is larger than the first load threshold;

each load data, that is, the load data obtained at intervals of a preset time, is a general term of the first load data and the second load data; for example, the second load threshold may be set to 75kg, 80kg, etc.

S420: and when the load data is greater than or equal to the second load threshold value, sending an overload prompt.

It should be noted that, in this embodiment of the present specification, optionally, the second load threshold is greater than the first load threshold and less than twice the first load threshold.

Preferably, after the overload reminding is sent, the vehicle can be further controlled to decelerate until the vehicle stops or the vehicle cannot be started, so as to remind a driver of reducing the load of the vehicle.

Further, as shown in fig. 5, in an embodiment of the present specification, after acquiring the first load data or after acquiring the first load data and the second load data, the method further includes:

s510: comparing each load data with a preset third load threshold, wherein the third load threshold is smaller than the first load threshold;

for example, the third loading threshold may be set to 0 kg.

S520: and when the load data is less than or equal to the third load threshold, sending an idle running prompt and controlling the vehicle not to start. For example, the central controller may control the brake pads to lock the tires and the motor controller and motor to be inactive.

When the vehicle is an electric power-assisted vehicle such as an electric vehicle, an electric motorcycle and the like, the vehicle is controlled not to be started when the load of the vehicle is zero, even if a user triggers an acceleration handle of the vehicle by mistake or a circuit of the acceleration handle breaks down to send an acceleration signal to the motor controller, the motor controller does not work under the control of the central controller or the motor controller enables the motor to not work under the control of the central controller, so that the vehicle cannot be started in an accelerated manner, and the occurrence of accidents caused by the runaway of the electric vehicle in the idle state is avoided.

Preferably, the third loading threshold may also be set to a value of 25kg, 30kg, etc., i.e., about the weight of a child. When a user places an article on a vehicle and does not get on the vehicle, the vehicle is prohibited from starting, and loss caused by vehicle fleeing and article falling is avoided. When a child rides on the vehicle and an annual caregiver is not on the vehicle, if the child triggers the accelerating handle by mistake, the vehicle is not started to avoid the injury to the child caused by the vehicle jumping out; and also sends no-load running reminding, for example, reminding the parents by sending out reminding warning sound through a loudspeaker 11 or lighting a headlamp and the like.

In some possible embodiments, the method further comprises:

comparing the third load data with a preset fourth load threshold;

illustratively, the fourth threshold may be set to 10kg, but may be other values, such as 15 kg.

When the weight of article surpassed fourth load threshold value in the bicycle basket, can lead to the fact the influence to the life of bicycle basket and the steadiness that the bicycle basket is connected with the locomotive, carry the thing overweight and can lead to the bicycle basket to warp even broken (for example the bicycle basket that materials such as plastics made), or break away from and then can bump into the wheel and cause danger at the vehicle in-process of riding from locomotive connecting portion. In addition, dangerous driving behaviors such as placing a child at a basket exist, and the dangerous driving monitoring method provided by the embodiment of the specification can monitor the overweight phenomenon of the loaded object through the first pressure sensor arranged at the basket.

In some possible embodiments, the method further comprises:

and when the user does not hold the handle with both hands and exceeds a preset time threshold value, controlling the motor of the electric vehicle to decelerate.

During the actual riding of the vehicle, there are some cases of single-handed riding that are inevitable, for example, the user holds the glasses. However, when the user keeps riding with one hand for a long time (for example, a call receiving and making state), there is a risk that the headstock cannot be effectively balanced, and a fall is caused. Therefore, it is preferable to control the vehicle to gradually decelerate when the user rides with one hand for a time period greater than or equal to a preset first duration threshold (for example, the first duration threshold may be set to 10s, 15s, or other values). This is because, if the vehicle is directly stopped or the traveling speed is suddenly reduced and the user is in a state of riding with one hand, the user is likely to fall down when the speed is suddenly reduced. Further, when the time for one-hand riding of the user is greater than or equal to a second duration threshold (the second duration threshold is greater than the first duration threshold, for example, the second duration threshold may be set to a value of 40s, 1min, or the like), the vehicle is further controlled to decelerate until the user holds the handle with both hands or the running speed gradually decreases to zero, so as to prevent the user from being in the one-hand riding state for a long time. In some preferred embodiments, the rate of decrease of the travel speed may also be controlled.

When the vehicle is an electric scooter, the method may further comprise:

acquiring friction force data of the vehicle brake;

the friction force data can be obtained through a displacement sensor arranged at the brake handle, when a user pinches the brake handle, the brake handle rotates to a certain degree, and therefore the central controller can obtain the friction force data according to the rotation angle of the brake handle obtained by the displacement sensor. When the brake handle is pinched, the brake pad is driven to be tightly attached to the wheel hub, so that friction force data can be obtained through a pressure sensor or a displacement sensor and the like arranged at the brake pad.

Comparing the friction data with a preset friction threshold;

controlling acceleration of the vehicle to disable acceleration when the friction data is greater than or equal to a friction threshold.

Namely, when the brake handle is pulled and meets the preset friction force condition, the central controller controls the acceleration handle to be incapable of sensing acceleration information, namely, the acceleration is incapable of being accelerated while braking.

In the actual scene of riding, if pinch the brake handle of one side when accelerating, can make the tire that corresponds with the brake handle of pinching skid, in the serious time, can lead to the locomotive perk or the rear of a vehicle to lift the condition (the galloping, the phenomenon of overturning) that only a tire contacted with ground, cause very big danger easily. Therefore, in the embodiment of the specification, acceleration is not allowed while braking, so that the situation can be avoided, and meanwhile, the service life of the brake pad can be prolonged.

The central controller can also send the acquired friction force data to a user and a vehicle management department so that the user and the vehicle management department can obtain the residual service life condition of the brake pad according to the friction force data analysis, and when the residual service life of the brake pad is short, a vehicle owner is reminded to replace the brake pad in time so as to improve the riding safety.

In some possible embodiments, gravity sensors may also be mounted on the front and rear tires to monitor whether the tires are in contact with the ground, allowing the vehicle to accelerate when both tires are in contact with the ground at the same time; otherwise, the vehicle is made to decelerate or fail to accelerate or fail to launch.

In addition, the dangerous driving monitoring method provided by the embodiment herein can also supervise the speeding behavior according to the speed information detected by the speed sensor:

comparing the speed information with a preset second speed threshold;

for example, the second speed threshold may be set to 40km/h, 45km/h, or other values.

And when the speed information is greater than or equal to a preset second speed threshold, controlling the vehicle to decelerate so that the running speed of the vehicle is always kept below the second speed threshold, thereby avoiding potential safety hazards caused by overspeed running. In addition, the output power of the motor can be set, so that the maximum running speed of the vehicle is the second speed threshold, and the problem of overspeed running can be solved from the source by specifically controlling the output power of the motor of the electric moped.

Further, in some preferred embodiments, the maximum driving speed of the vehicle may be adjusted according to a load of the electric bicycle, and the larger the load is, the smaller the maximum driving speed is.

In summary, the dangerous driving monitoring method provided in the embodiment of the present specification judges whether multiple dangerous driving behaviors such as no-load, overload, illegal man-carrying, overweight carrying, single-hand riding, single-wheel riding, and overspeed occur through load data, friction data of brake handles, and traveling speed data respectively obtained by the pressure sensors, the displacement sensors, and the speed sensors, and has the advantages of wide supervision range, simple, timely, accurate judgment, low cost, and easy popularization; and through the mode of reminding, the mode of slowing down or not allowing the vehicle to start and the mode of linking punishment with the supervision department, the emergence of above-mentioned dangerous driving behavior has greatly been reduced, is favorable to improving user's safe driving consciousness, ensures user's personal and property safety.
