Description

A vehicle door warning method, device and system

technical field

The invention relates to the field of Internet of Vehicles, and in particular, to a vehicle door warning method, device and system.

Background technique

With the improvement of people's economic level and consumption level, automobiles have become an indispensable means of transportation for people to travel, but the resulting traffic accidents are also gradually increasing.

However, among the many traffic accidents, in addition to the common traffic accidents caused by drunk driving, fatigue driving, speeding, etc., there is also a frequent traffic accident, that is, the driver or passenger in a parked car suddenly opens the door , so that the vehicle or pedestrian behind the door corresponding to the opened door has no time to avoid it, resulting in a mild or severe traffic accident.

Under the prior art, there are the following two schemes to avoid the occurrence of the above-mentioned traffic accident:

Option 1: Install sensors around the car door. When the sensors around the door sense that the door is opened, it will transmit the sensed signal to the controller, and the controller will control the light-emitting component to emit light to remind people behind the door. The personnel avoided in time.

However, in scheme 1, it is necessary to rely on people outside the car to detect the light in time, and only after being alerted can the collision be avoided, so the effect is not very obvious.

Option 2: Install an autonomous sensor on the car, and use the autonomous sensor to detect whether there are pedestrians, vehicles or obstacles behind the door. When detected, it will prompt the driver or passenger in the car whether the current surrounding environment is safe.

Although the second scheme can also reduce the occurrence of such traffic accidents, in this scheme, the accuracy of the autonomous sensor is easily affected by the surrounding environment (for example, there are many obstacles in the surrounding environment, or there are high-speed motorcycles), therefore, the effect is not very obvious.

In view of this, a new prompt scheme needs to be designed to overcome the above-mentioned shortcomings.

The solution of the present invention will be described in detail below by way of specific examples, of course, the present invention is not limited to the following examples.

Referring to FIG. 1 , in the embodiment of the present invention, a vehicle door warning system is designed, which at least includes a positioning device 10 , a wireless communication device 11 , a data processing device 12 and an alarm device 13 , wherein,

a positioning device 10, the positioning device 10 is connected with the data processing device 12, and is used for determining the first position state information of the vehicle, and outputting the first position state information to the data processing device 12;

A wireless communication device 11, the wireless communication device 11 is connected to the data processing device 12 for receiving the second position status information sent by at least one surrounding vehicle, and sending the received second position status information to the data processing device 12 ;

The data processing device 12 is configured to send alarm information to the alarm device 13 when it is determined based on the first position state information and the second position state information that a preset trigger condition is satisfied;

The alarm device 13 is connected to the data processing device 12 and is used for receiving and executing the alarm information sent by the data processing device 12 .

Preferably, in this embodiment of the present invention, the door warning system may further include a door state detection device 14, which is connected to the data processing device 12 for detecting the door state of the vehicle and outputting the door state. to the data processing device 12 .

Preferably, in the embodiment of the present invention, the vehicle door warning system may further include a vehicle door control device 15, and the vehicle door control device 15 is connected to the data processing device 12 for receiving the control information sent by the data processing device 12, and executing the control information, That is, when the warning device 13 warns the driver and/or passengers that the door of the vehicle is not suitable to be opened, the auxiliary warning device 13 temporarily locks the door until the safety is confirmed, and then releases the lock.

Specifically, before the door warning system executes the work flow, the door shape data and the door opening angle data of the vehicle are stored in a designated storage area in advance, where the designated storage area may be the storage area of the data processing device in the door warning system , and can also be a storage area where the data can be read by the door warning system when it executes the work flow, which is not limited here.

Referring to FIG. 2, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The specific process of the door warning in the embodiment of the present invention is as follows:

Step 200: The door warning system acquires the first position status information of the vehicle and the second position status information sent by at least one surrounding vehicle.

Specifically, in the embodiment of the present invention, surrounding vehicles (eg, cars, motorcycles, bicycles) will periodically broadcast their second position status information to the surrounding, so that the door warning system will obtain the information through the wireless communication device. Second position status information of surrounding vehicles, where the second position status information may include latitude and longitude, vehicle speed, vehicle acceleration, vehicle driving direction, vehicle historical path, etc. The wireless communication device in the system broadcasts to the outside, and the short-range communication device that can be installed can broadcast to the outside through the short-range communication device, and the preferred period is 100 milliseconds.

Further, the door warning system determines the first position state information of the vehicle through the positioning device in its own system, and transmits the obtained first position state information to the data processing device in its own system through the positioning device, wherein the The first position state information of the vehicle may include the latitude and longitude of the vehicle, vehicle speed, vehicle acceleration, vehicle driving direction, vehicle history path, and the like.

Of course, in the embodiment of the present invention, after obtaining the first position status information of the vehicle, the data processing device of the door warning system can periodically broadcast the first position status information of the vehicle to surrounding areas through the wireless communication device in the system. The vehicle may also not broadcast the first position status information of the vehicle to surrounding vehicles. Preferably, the period for the door warning system to broadcast the first position information of the vehicle may also be set to 100 milliseconds, which is not limited here.

Step 210 : The door warning system determines whether there is at least one surrounding vehicle within the door opening range of the vehicle, if so, go to Step 220 ; otherwise, go to Step 240 .

Specifically, the door warning system determines whether there is at least one surrounding vehicle within the door opening range of the vehicle based on the first position status information of the vehicle and the received second position status information of at least one surrounding vehicle.

Further, the data processing device in the door warning system determines the relative relationship between the vehicle and the at least one surrounding vehicle in real time based on the first position status information of the vehicle and the received second position status information of at least one surrounding vehicle. Then, read the pre-stored door shape data and door opening angle data of the vehicle in the designated storage area, and determine the collision-prone area of the door opening range of the vehicle based on the door shape data and door opening angle data. By comparing the obtained relative position area and the collision-prone area whether there is an overlapping area, it is judged whether the preset trigger conditions are met. If there is an overlapping area, it can be determined that there is at least one surrounding vehicle within the door opening range of the vehicle. If the overlapping area is present, it can be determined that at least one surrounding vehicle does not exist within the door opening range of the vehicle.

Referring to Fig. 3, in the embodiment of the present invention, preferably, whether there is an overlapping area between the relative position area and the collision-prone area can be determined by the following methods:

Step 1: Calculate the outermost horizontal distance R of the door opening of the vehicle. Preferably, the R value can be obtained by the following formula:

R=L*cosα+r

Among them, L is the length of the door of the vehicle, and α is the maximum angle that the vehicle can open.

Step 2: Calculate the relative position M of the vehicle and at least one surrounding vehicle, specifically, the horizontal distance between the center point 0 of the vehicle and the center point 1 of the surrounding vehicle B.

Step 3: Calculate the safety distance d ₁ between the vehicle and surrounding vehicles. Preferably, the value of d ₁ can be obtained by the following formula:

d ₁ =v*(t ₁ +t ₂ /2+t ₃ )+v ² /2*φ*g+d ₀

Among them, v is the speed of surrounding vehicles;

t ₁ is the sum of the driver's reaction time and the braking coordination time.

t ₂ is the time for the deceleration to increase, the value range is 0.1s-0.2s, and the value can be selected according to the actual situation;

_t3 is the time from the door opening to closing, which is the statistical value obtained after multiple trainings;

φ is the pavement adhesion coefficient, and the coefficient is different under different pavements. It is 0.8 for cement pavement in non-rainy days and 0.2 for cement pavement in rainy days. The value can be selected according to the actual situation;

g is 9.8m/s ² ;

d ₀ is the minimum required safety distance between the surrounding vehicles and the vehicle after parking, which can be 0 and can be valued according to the actual situation.

Step 4: Determine whether there is _an overlapping area by judging the size of (Mm) and R, as well as the size of the longitudinal distance D of the surrounding vehicle B and the safety distance d1.

Specifically, only when (Mm) is greater than the outermost horizontal distance R, and the longitudinal distance D is greater than the safety distance d ₁ , can it be determined that there is no overlapping area between the relative position area and the collision-prone area, that is, the surrounding vehicle is located in the door of the own vehicle is open The outermost horizontal distance at the maximum angle is outside, and the longitudinal distance between the surrounding vehicles and the vehicle is greater than the preset safety distance, otherwise, there is an overlapping area.

So far, after the above steps, it can be determined whether there is an overlapping area between the relative position area and the collision-prone area, that is, it can be determined whether there is at least one surrounding vehicle within the door opening range of the vehicle. Step 240.

Step 220 : The door warning system determines whether the door of the vehicle is about to be opened, if so, go to Step 230 , otherwise, go back to Step 210 .

Specifically, when the data processing device in the door warning system determines that there is at least one surrounding vehicle in the door opening range of the vehicle, the door status detection device will detect the door status (eg, open, closed, about to open, about to close) of the vehicle. ), when the door status detection device detects through a sensor or sensor that the driver or passenger in the car intends to open the door (after touching the door handle, but before the door is opened), the door status detection device will include a The door status information that the door of the vehicle is about to be opened is sent to the data processing device, and the data processing device sends alarm information to the alarm device when it confirms that the door of the vehicle is about to be opened.

In the embodiment of the present invention, a preferred implementation is that, after step 210, when it is determined that there is at least one surrounding vehicle within the door opening range of the vehicle, the data processing device does not need to confirm that the door of the vehicle is about to be opened through the door state detection device When the alarm information is sent to the alarm device, as long as it is determined that there is at least one surrounding vehicle within the door opening range of the vehicle, the alarm information is directly sent to the alarm device, without going through step 220, but directly entering step 230.

Step 230: The door warning system warns the driver and/or passengers of the vehicle.

Specifically, after receiving the warning information sent by the data processing device, the warning device in the door warning system will execute the warning information to warn the driver and/or passengers of the vehicle that the door of the vehicle is not suitable to be opened at present. Voice broadcast, flashing lights, etc. can be used, which are not limited here.

Further, in the embodiment of the present invention, when the alarm device in the vehicle door warning system executes the alarm information, the vehicle door alarm system can also perform auxiliary warning through the vehicle door control device, that is, when the data processing device notifies the alarm device to execute the alarm information, At the same time, the controller in the door control device is triggered to temporarily lock the door of the vehicle until it is confirmed that there is no at least one surrounding vehicle within the opening range of the door of the vehicle, and the lock is released.

Of course, when the vehicle door control device controls the vehicle doors of the vehicle, the vehicle doors may be all vehicle doors of the vehicle, or only the vehicle doors that are detected to be opened.

Step 240 : the door warning system determines whether the door of the vehicle is opened, if so, go to Step 250 , otherwise, go to Step 210 .

Specifically, when the data processing device in the door warning system determines that there is no at least one surrounding vehicle within the door opening range of the vehicle, the door state detection device is still performing the task of detecting the door, and sends the detected door state to the A data processing device, the data processing device determines whether the door of the vehicle is opened according to the received state of the door, and if so, executes step 250 , otherwise, executes step 210 .

Step 250: The door warning system determines that the driver and/or passenger of the vehicle has opened the door of the vehicle, and broadcasts the door opening information and door offset distance of the vehicle to at least one surrounding vehicle until the door of the vehicle is determined closure.

Specifically, the data processing device in the door warning system analyzes the received door state to determine that the driver and/or passenger of the vehicle has opened the door of the vehicle, and then receives the vehicle's information sent by the door state detection device. Door opening information and door offset distance, and send the door opening information and door offset distance to the wireless communication device, and trigger the wireless communication device to send the vehicle's door opening information and door offset distance to surrounding vehicles through broadcasting, Until the data processing device determines through the door state detection device that the door of the own vehicle is completely closed, it stops broadcasting to surrounding vehicles.

Certainly, when the wireless communication device broadcasts the door opening information and the door offset distance to surrounding vehicles, the door opening information and the door offset distance may be sent together with the first position state information, or may be sent separately.

Further, when the driver of the surrounding vehicle receives the door opening information and the door offset distance, it is determined that the door of a vehicle is open at a specific location on a road. The position of the own vehicle and the door offset distance of the vehicle opening the door are used to estimate the safe driving area for timely avoidance.
