The following describes a method, an apparatus, a vehicle-mounted device, and a computer-readable storage medium for collision avoidance reminding according to embodiments of the present application with reference to the drawings.
First, a method for providing a collision avoidance warning according to an embodiment of the present application will be specifically described with reference to fig. 1.
Fig. 1 is a schematic flow chart of a method for collision avoidance reminding according to an embodiment of the present application.
As shown in fig. 1, the method of collision avoidance reminding of the present application may include the following steps:
Specifically, the method for reminding collision avoidance provided by the embodiment of the present application can be executed by the device for reminding collision avoidance provided by the embodiment of the present application. The anti-collision reminding device can be configured in the vehicle-mounted equipment of the first vehicle, so that when the distance between the first vehicle and the second vehicle is small, the distance is sent to the second vehicle through the light fidelity LiFi communication component, and the second vehicle generates first anti-collision reminding information according to the distance.
The vehicle-mounted device in the embodiment of the present application may be any hardware device capable of performing data processing, such as a smart phone, a tablet computer, a personal digital assistant, an intelligent wearable system, and the like. The application takes the vehicle-mounted device as an example for explanation.
It is understood that the second vehicle in front of the first vehicle may be a vehicle traveling in the same direction as the first vehicle, or may be a vehicle traveling in opposite direction to the first vehicle, and the present application does not limit this, and the present application takes the first vehicle and the second vehicle as an example for explanation.
Specifically, the vehicle distance between the first vehicle and the second vehicle may be acquired in the following various ways.
The distance between the first vehicle and the second vehicle may be a distance between a certain portion of the first vehicle and a certain portion of the second vehicle, for example, a distance between a front wheel of the first vehicle and a rear wheel of the second vehicle, and may be defined as necessary. Since the frontmost end of the first vehicle collides with the rearmost end of the second vehicle when the first vehicle collides with the second vehicle, the headlights of the first vehicle are generally located at the frontmost end of the first vehicle, and the taillights of the second vehicle are generally located at the rearmost end of the second vehicle, the present application may define the distance between the headlights of the first vehicle and the taillights of the second vehicle as the vehicle distance between the first vehicle and the second vehicle.
In a first mode
The first vehicle obtains the distance between the first vehicle and the second vehicle through the distance sensor.
Specifically, a vehicle distance sensor may be configured in the first vehicle, so that the collision avoidance reminding device may acquire the vehicle distance from the second vehicle through the vehicle distance sensor.
Mode two
The method comprises the steps that a first vehicle acquires image information in front and identifies the position of a vehicle lamp in the image information; and acquiring the distance between the vehicle and the second vehicle according to the position of the lamp.
Specifically, an image acquisition device may be disposed at a preset position of the first vehicle, for example, a camera is mounted on a front windshield of the first vehicle, so that the camera is used to photograph the front of the first vehicle, and when the photographed image includes the second vehicle, the image information in the image may be identified to determine a position where a lamp of the second vehicle is located, so as to determine a distance between the first vehicles according to the position of the lamp of the second vehicle.
The method for identifying the position of the car light in the image may be any method for identifying the image to determine the position of an object in the image in the related art, which is not described herein again.
It is understood that when the second vehicle travels ahead of the first vehicle in the same direction as the first vehicle, the position of the lamp in the image information is the position of the tail lamp of the second vehicle.
In a specific implementation, any other manner capable of detecting the distance may be used to obtain the distance between the first vehicle and the second vehicle, for example, the distance between the headlight of the first vehicle and the tail lamp of the second vehicle may be calculated according to the time difference between the time when the headlight of the first vehicle emits the visible light and the time when the headlight of the second vehicle receives the light reflected by the tail lamp of the second vehicle and the speed of light, so that the distance between the headlight of the first vehicle and the tail lamp of the second vehicle may be calculated by using the distance between the visible light and the second vehicle, which is not limited in this application.
And 102, judging whether the vehicle distance is smaller than a first preset threshold value.
The first preset threshold value may be a minimum safe distance between the first vehicle and the second vehicle when the first vehicle and the second vehicle travel in the same direction. The setting may be made in accordance with factors such as a prescribed vehicle distance between the first vehicle and the second vehicle on the road on which the first vehicle and the second vehicle travel, the vehicle speeds of the first vehicle and the second vehicle, and the like.
For example, if the road on which the first vehicle and the second vehicle are currently traveling defines a safe inter-vehicle distance of 50 meters or more, the first preset threshold may be set to 50 meters.
And 103, if the distance between the vehicles is smaller than a first preset threshold value, the distance between the vehicles is sent to the second vehicle by the first vehicle through the light fidelity LiFi communication assembly, so that the second vehicle generates first anti-collision reminding information according to the distance between the vehicles.
The first anti-collision reminding information may include information such as whether a vehicle is in front of or behind the vehicle and specific vehicle distance information, and the application is not limited to this.
Specifically, a first LED array can be installed to the headlight of first vehicle, and drive the first light fidelity LiFi transmission module of first LED array, and first LiFi transmission module links to each other with first LED array, thereby the device that the anticollision was reminded can be when confirming that the vehicle distance between first vehicle and the second vehicle is less than first preset threshold value, can encode in order to form the coding data through first LiFi transmission module to the vehicle distance, and send the tail lamp of second vehicle to the coding data through first LED array.
The tail lamp of the second vehicle can be provided with a first Photo Diode (PD) array and a second LiFi transmission module for driving the first PD array, and the second LiFi transmission module is connected with the first PD array, so that the tail lamp of the second vehicle can receive coded data sent by the first LED array in a headlight of the first vehicle through the first PD array, and the coded data received by the first PD array is decoded by the second LiFi transmission module to obtain the distance between vehicles.
That is, the wifi LiFi communication assembly may include a first LED array in a headlight of a first vehicle, a first LiFi transmission module, a first PD array in a taillight of a second vehicle, a second LiFi transmission module.
Wherein the first LED array may be a partial LED array in a headlight of the first vehicle for LiFi communication, and the other LED arrays are for illuminating the front of the first vehicle. And the first LED array can emit visible light and can also work in an infrared frequency band, so that the data transmission distance of the first vehicle and other vehicles during communication is increased, and the application does not limit the data transmission distance.
It should be noted that, the first vehicle and the second vehicle may both be provided with vehicle-mounted devices, and the vehicle-mounted devices are provided with anti-collision reminding devices, so that after the anti-collision reminding device of the second vehicle obtains the vehicle distance sent by the first vehicle through the optical fidelity LiFi communication module, the first anti-collision reminding information may be generated according to the vehicle distance, and the vehicle-mounted devices of the second vehicle remind the driver in the second vehicle.
Specifically, the vehicle-mounted device of the second vehicle can remind the driver in the second vehicle in a mode of voice broadcasting the first anti-collision reminding information or a mode of playing the alarm sound, and can remind the driver in the second vehicle in other modes, and the method is not limited to this.
In addition, when the distance between the first vehicle and the second vehicle is smaller than the first preset threshold, the vehicle-mounted device in the first vehicle may also remind the driver in the first vehicle to make a corresponding anti-collision measure, such as deceleration, etc., for the driver in the first vehicle, and the reminding manner may be the manner described above, or may be another manner, which is not limited in this application.
It should be noted that, in the above embodiment, the first vehicle is a rear vehicle, and the second vehicle is a front vehicle, so that the distance is acquired by the rear vehicle and sent to the front vehicle through the optical fidelity LiFi communication component, so that the front vehicle generates the first anti-collision reminding information according to the distance. In a possible implementation form, the front vehicle can acquire the vehicle distance between the front vehicle and the rear vehicle, and then the vehicle distance is sent to the rear vehicle through the light fidelity LiFi communication assembly when the vehicle distance is smaller than a first preset threshold value, so that the rear vehicle generates the anti-collision reminding information according to the vehicle distance.
That is, in an exemplary embodiment, the tail light of the second vehicle may also have a second LED array, and a third LiFi transmission module driving the second LED array, where the third LiFi transmission module is connected to the second LED array, and is configured to encode the vehicle distance to form encoded data, and transmit the encoded data through the second LED array.
The headlight of the first vehicle can also be provided with a second PD array, and a fourth LiFi transmission module for driving the second PD array is connected with the second PD array and used for decoding the coded data received by the second PD array to acquire the distance between vehicles.
In addition, first vehicle also can be as preceding vehicle, communicates through light fidelity LiFi communication subassembly with the rear vehicle, namely, the tail lamp of first vehicle can both include the LED array that is used for carrying on the LiFi communication, the light fidelity LiFi transmission module who links to each other with the LED array, and including the PD array that is used for carrying on the LiFi communication again, and the light fidelity LiFi transmission module who links to each other with the PD array to when the vehicle distance between first vehicle and the rear vehicle is less than first preset threshold value, first vehicle or rear vehicle pass through the vehicle distance that light fidelity LiFi communication subassembly sent according to another vehicle and generate first anticollision warning information.
In addition, the light fidelity LiFi transmission module may be disposed in a lamp of a vehicle as described in the foregoing embodiments, or may be disposed in an on-board device to encode and decode a vehicle distance, which is not limited in this application.
In an exemplary embodiment, a device for receiving an optical signal emitted by an LED array of another vehicle in a certain vehicle may also be an optical filter, a photodetector, or the like mounted at a front end or a rear end of the vehicle, so that after an on-board device in the vehicle detects the optical signal by the photodetector or the like, the on-board device may receive the optical signal by the photodetector, and perform certain processing to obtain a vehicle distance between the vehicle and the other vehicle, so that the on-board device further performs analysis processing on the vehicle distance to generate collision avoidance reminding information.
Referring to fig. 2 to 4, cameras may be disposed in front windshields and rear windshields of the vehicles a and B to obtain a vehicle distance from other vehicles, and LED arrays and light fidelity LiFi transmission modules (not shown in the drawings) connected to the LED arrays may be disposed in headlights and taillights of the vehicles a and B, so that the vehicle distance may be transmitted to other vehicles through the LED arrays and the light fidelity LiFi communication assemblies when the vehicle distance from other vehicles is smaller than a first preset threshold. Wherein the content of the first and second substances,
fig. 2 is a schematic side view of a vehicle a and a vehicle B provided with a light fidelity LiFi communication assembly and a camera. Fig. 3 is a rear view of a vehicle a or a vehicle B provided with a light fidelity LiFi communication assembly and a camera. Fig. 4 is a front view of a vehicle a or a vehicle B provided with a light fidelity LiFi communication assembly and a camera.
It can be understood that, in the method for reminding collision avoidance provided in the embodiment of the present application, the first vehicle and the second vehicle communicate through the optical fidelity LiFi communication component, and since the bottom layer of the Li-Fi protocol is compatible with the WiFi802.11 baseband, when data is transmitted, one-to-many or many-to-one simultaneous transmission can be realized by using the TDD protocol in WiFi. In addition, because the optical communication mode is adopted to transmit data, the frequency band is not limited, so that the interference is avoided, and the reliability of data transmission is ensured. And because when the vehicle distance between first vehicle and the second vehicle is less than first preset threshold, first vehicle passes through light fidelity LiFi communication subassembly with the vehicle distance send to the second vehicle to make the second vehicle generate first anticollision warning information according to the vehicle distance, realized at night, heavy fog, torrential rain, there is not the street lamp, also can remind the driver when two cars are close under adverse conditions such as vehicle event data recorder damage, and because LiFi communication has low time delay nature, consequently can also in time remind the driver when two cars are too close or driving speed is too fast, thereby avoid the emergence of traffic accident, guarantee the safety of traveling of vehicle.
The method for reminding collision avoidance provided by the embodiment of the application comprises the steps that first vehicles obtain the distance between the first vehicles and second vehicles in front, then whether the distance is smaller than a first preset threshold value is judged, if the distance is smaller than the first preset threshold value, the first vehicles send the distance to the second vehicles through the light fidelity LiFi communication assembly, and therefore the second vehicles generate first collision avoidance reminding information according to the distance, therefore, drivers can be reminded when the distance between the two vehicles is short under severe conditions of night, heavy fog, heavy rain, no street lamps and the like, and the drivers can be reminded in time when the distance between the two vehicles is too short or the driving speed is too high due to the fact that the LiFi communication has low time delay performance, so that traffic accidents are avoided, and the driving safety of the vehicles is guaranteed.
Through the analysis, when the vehicle distance between the first vehicle and the second vehicle is smaller than a first preset threshold value, the first vehicle can send the vehicle distance to the second vehicle through the light fidelity LiFi communication assembly, so that the second vehicle generates first anti-collision reminding information according to the vehicle distance, and in a possible implementation form, the second vehicle can be subjected to emergency early warning when the vehicle distance between the first vehicle and the second vehicle is smaller, so that the second vehicle can be avoided in time, and accidents are avoided. In the following, with reference to fig. 5, the method for providing a collision avoidance warning according to the embodiment of the present application is further described with respect to the above situation.
Fig. 5 is a flowchart illustrating a method for collision avoidance reminding according to another embodiment of the present application.
As shown in fig. 5, the method of collision avoidance reminding of the present application may include the following steps:
in step 201, a first vehicle acquires a distance between the first vehicle and a second vehicle ahead.
Specifically, if the vehicle distance is greater than or equal to the first preset threshold, the vehicle distance between the first vehicle and the second vehicle ahead is continuously acquired.
The second preset threshold may be set as needed, for example, 80%, 70%, and so on of the first preset threshold.
And 204, limiting the speed of the first vehicle, and sending second anti-collision reminding information to the second vehicle through the light fidelity LiFi communication assembly.
The second anti-collision reminding information may include information such as whether there is a vehicle in front of or behind the vehicle and specific vehicle distance information, and the application is not limited to this.
And step 205, sending the first anti-collision reminding information to the second vehicle through the light fidelity LiFi communication assembly so that the second vehicle generates the first anti-collision reminding information according to the vehicle distance.
And the reminding level of the second anti-collision reminding information is higher than that of the first anti-collision reminding information.
Specifically, if the vehicle distance between the first vehicle and the second vehicle is smaller than a first preset threshold value and smaller than a second preset threshold value, it may be considered that the vehicle distance between the first vehicle and the second vehicle is insufficient to enable the drivers of the first vehicle and the second vehicle to make corresponding vehicle collision prevention measures such as deceleration, and therefore, the vehicle speed of the first vehicle may be limited, and the second collision prevention reminding information is sent to the second vehicle through the optical fidelity LiFi communication component to remind the driver of the second vehicle to avoid being collided by the first vehicle. Therefore, when the distance between the first vehicle and the second vehicle is too small, the occurrence of traffic accidents is further avoided, and the driving safety of the vehicles is ensured.
If the vehicle distance between the first vehicle and the second vehicle is smaller than a first preset threshold value and larger than or equal to a second preset threshold value, the vehicle distance between the first vehicle and the second vehicle can be considered to be enough to enable drivers in the first vehicle and the second vehicle to take corresponding anti-collision measures, and therefore the first anti-collision reminding information can be sent to the second vehicle only through the light fidelity LiFi communication assembly, so that the second vehicle generates the first anti-collision reminding information according to the vehicle distance to remind the driver in the second vehicle to avoid being collided by the first vehicle, and the vehicle speed of the first vehicle is not limited.
The specific implementation process and principle of the steps 201, 202, and 205 may refer to the specific description of the above embodiments, which is not described herein again.
The method for reminding collision avoidance provided by the embodiment of the application comprises the steps that first, a first vehicle obtains a distance between the first vehicle and a second vehicle in front of the first vehicle, when the distance is larger than or equal to a first preset threshold value, the distance between the first vehicle and the second vehicle in front of the second vehicle is continuously obtained, when the distance is smaller than the first preset threshold value, whether the distance is smaller than a second preset threshold value is further judged, wherein the second preset threshold value is smaller than the first preset threshold value, if yes, speed limitation is carried out on the first vehicle, second collision avoidance reminding information is sent to the second vehicle through a light fidelity LiFi communication assembly, and if not, the first collision avoidance reminding information is sent to the second vehicle through the light fidelity LiFi communication assembly, so that the second vehicle generates the first collision avoidance reminding information according to the distance. Therefore, the driver can be reminded when the distance between the two vehicles is short under severe conditions of night, heavy fog, heavy rain, no street lamp and the like, and the driver can be reminded in time when the distance between the two vehicles is too short or the driving speed is too high due to the low time delay property of the LiFi communication, so that traffic accidents are avoided, and the driving safety of the vehicles is guaranteed.
