Detailed Description

The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein. The term "module" as used herein may be considered a software object executing on the computing system. The various modules, engines, and services herein may be considered as objects of implementation on the computing system.

The embodiment of the application provides a vehicle information transmission method, and an execution main body of the vehicle information transmission method can be the vehicle information transmission device provided by the embodiment of the application or a first vehicle integrated with the vehicle information transmission device. Wherein the first vehicle includes an LED lamp, a processor, a memory, and the like.

The following is a detailed description of the analysis.

referring to fig. 1, fig. 1 is a first flowchart of a vehicle information transmission method according to an embodiment of the present application, where the vehicle information transmission method includes the following steps:

101. The first vehicle acquires abnormal traveling information.

In the embodiment of the application, the vehicle detects the running state in real time, when the running state is detected to be the abnormal running state, the vehicle is determined to be a fault vehicle, the position information and the abnormal information of the vehicle are obtained, and the abnormal running information is generated according to the position information and the abnormal information of the fault vehicle.

The faulty vehicle may be the first vehicle, may be a third vehicle ahead of the first vehicle, may be a vehicle ahead of the third vehicle, or the like. The vehicle may comprise, among other things, any passenger or commercial vehicle, such as a car, truck, minivan, bus, etc. The vehicle may be a vehicle capable of full autonomous driving mode (e.g., unmanned), semi-autonomous driving mode, or non-autonomous driving mode.

In some embodiments, the abnormal driving information includes position information and abnormality information. The position information refers to the geographical position information of the vehicle, and the abnormal information refers to the information related to the abnormal running state of the vehicle. After the vehicle acquires the position information and the abnormality information, the vehicle generates abnormal traveling information based on the position information and the abnormality information. For example, the vehicle generates the abnormal traveling information by using the position information and the abnormal information as the contents of the abnormal traveling information, and in this case, the abnormal traveling information includes the position information and the abnormal information of the vehicle.

The method for acquiring the vehicle position information and the abnormal information in the scheme has various ways, such as acquiring the vehicle position through GPS positioning, base station positioning or WiFi positioning, and acquiring the abnormal information through a vehicle diagnosis system, or full-manual input of a user, semi-manual input of the user and the like. The embodiment of the present application does not specifically limit the manner of acquiring the position information and the abnormal information.

In some embodiments, the abnormality information includes an abnormal driving state and an abnormal cause.

in some embodiments, the abnormality information further includes a traveling speed, so that a second vehicle behind the first vehicle predicts a position of the vehicle over a period of time based on the position of the vehicle and the traveling speed.

the abnormal traveling state of the vehicle means a state in which a traffic accident, a breakdown, an abnormal traveling speed, or the like of the vehicle affects normal traveling of the first vehicle or the second vehicle. For example, the vehicle belongs to an abnormal running state when the vehicle is slowly running, and the running speed of the vehicle is abnormal, that is, the running speed is too low, which may affect the normal running of the first vehicle or the second vehicle. For another example, the vehicle is in an abnormal driving state during deceleration, and normal driving of the first vehicle or the second vehicle is affected by the deceleration, which is likely to cause rear-end collision.

In some embodiments, the abnormal driving information may further include identification information of vehicles, and each vehicle corresponds to unique identification information. Specifically, the identification information of the vehicle may be a license plate number of the vehicle.

102. and coding the abnormal running information to obtain a first digital signal.

In the embodiment of the application, after the first vehicle acquires the abnormal running information, the first vehicle performs binary coding processing on the abnormal running information to obtain a first digital signal represented by binary numbers. The first digital signal carries abnormal driving information, and the abnormal driving information can be obtained through decoding processing of the first digital signal. Where encoding is the process of converting information from one form/format to another, into information that can be processed and analyzed using a computer program. Common encoding processes in digital systems are: binary coding processing and decimal coding processing. The encoding process may specifically be performed by an encoder.

For example, if the abnormal traveling information of the faulty vehicle is "vehicle position, vehicle stop state, and tire burst", the "vehicle position, vehicle stop state, and tire burst" is encoded to obtain first digital signals indicated by "0" and "1". The embodiment of the present application does not specifically limit the specific display manner of the first digital signal. For example, the first digital signal may be presented in the form of a character string, such as the presentation of "0110100 … …". For example, the first digital signal may also be presented in the form of a matrix.

103. The first vehicle-driving LED lamp emits a first optical signal for communicating abnormal traveling information to the second vehicle in accordance with the first digital signal.

in an embodiment of the present application, a first vehicle-driven LED lamp emits a first light signal in accordance with a first digital signal. The first vehicle driving LED lamp emits the first light signal, and the first light signal can be emitted intermittently or once at intervals. The interval time of each time can be the same or different.

In addition, in the embodiment of the present application, the LED lamp of the vehicle is used to emit a light signal for information transmission. The LED lights of the vehicle may be the usual exterior lights of the vehicle, such as headlamps, position lights, fog lights, license plate lights, backup lights, turn signals, brake lights, and the like. The LED lamp of the vehicle may also be a light emitting diode that is arranged on the outer contour of the vehicle body specifically for emitting a light signal, which light emitting diode may or may not be detachable from the outer contour of the vehicle body.

it should be noted that the first optical signal emitted by the first vehicle does not have a fixed receiving object, and thus the first optical signal may not have a receiving object, or the first optical signal may also have one or more receiving objects. The devices (the devices having the receivers) in the first optical signal radiation range can receive the first optical signal, and the receiving object can be specifically a second vehicle, a roadside infrastructure, and the like.

For example, the roadside infrastructure provided with the receiver converts a first optical signal into an electrical signal when the receiver detects the first optical signal sent by a first vehicle, converts the electrical signal into a digital signal, decodes the digital signal to obtain abnormal driving information of a fault vehicle, determines a danger level according to the abnormal driving information, and sends a distress signal to a traffic police when the danger level is greater than a threshold value.

In some embodiments, the roadside infrastructure further emits a third light signal through the LED lamp after obtaining the abnormal driving information that the danger level is greater than the threshold value, the third light signal being used to warn the passing vehicle. Wherein, the communication range of the third optical signal can be larger than or equal to the communication range of the first optical signal.

as can be seen from the above, in the vehicle information transmission method provided in this embodiment, when the first vehicle obtains the abnormal driving information, the abnormal driving information is encoded to obtain the first digital signal, and the first vehicle drives the LED lamp to emit the first optical signal according to the first digital signal, so that the abnormal driving information can be timely notified to the second vehicle even in a severe environment, thereby ensuring timeliness of information transmission during driving, and reducing traffic accidents caused by untimely information transmission.

referring to fig. 2, fig. 2 is a second flow chart of the vehicle information transmission method according to the embodiment of the present application, which will be described in detail below.

in this embodiment, 101 may include:

1011. When the first vehicle detects that the running state is the abnormal running state, first position information and abnormal information of the first vehicle are acquired.

1012. and generating abnormal driving information according to the first position information and the abnormal information.

In the embodiment of the present application, the faulty vehicle is the first vehicle. Referring to fig. 3, fig. 3 is a schematic view of a first scenario of a vehicle information transmission method according to an embodiment of the present application. In this scenario, the first vehicle A₁Is a faulty vehicle, A₁the vehicle is in an abnormal driving state when the vehicle detects the tire burst through the fault detection system, and at the moment, A is obtained₁Generating abnormal driving information according to the first position information and the abnormal information of the vehicle, and converting the abnormal driving information into a first digital signal, A₁the vehicle drives the LED lamp to emit a first light signal according to the first digital signal, and the first light signal passes throughThe signal timely transmits the abnormal running information to the second vehicle A₂vehicle such that the second vehicle A₂Vehicle aware front faulty vehicle a₁Vehicle, second vehicle A₂The vehicle can slow down the running speed in time, thereby avoiding traffic accidents caused by untimely information transmission.

In some embodiments, before acquiring the first position information and the abnormality information of the first vehicle, the method further includes:

When the first vehicle detects that the driving state is the abnormal driving state, acquiring the alarm level of the abnormal driving state;

and if the alarm level is greater than the preset level, acquiring first position information and abnormal information of the first vehicle.

According to the scheme, the first vehicle monitors the running state of the first vehicle in real time through the fault diagnosis system, and when the first vehicle detects that the running state is the abnormal running state, the alarm level of the abnormal running state is obtained. The abnormal driving states have respective corresponding alarm levels, and the alarm levels of any two abnormal driving states may be the same or different.

Note that, in this embodiment, the warning level is used to indicate the degree of urgency of the abnormal driving state. The higher the warning level is, the higher the emergency degree of the abnormal driving state is, the greater the possible damage is, and the more timely notification of the second vehicle and the rescue personnel is required. For example, the warning level of the vehicle fault state caused by the leakage of the oil tank is obviously higher than the vehicle fault state caused by the tire burst because the oil tank leakage has the explosion risk compared with the tire burst, and the second vehicle and the rescue workers need to be informed in time so as to be convenient for the second vehicle and the rescue workers to process in time.

In some embodiments, when the first vehicle detects that the driving state is the abnormal driving state, the obtaining of the warning level of the abnormal driving state may be implemented as follows: the first vehicle acquires a running state in real time, matches the running state with a preset abnormal running state, and if the matching is successful, takes the running state as the abnormal running state and acquires the alarm level of the abnormal running state.

in some embodiments, the first vehicle may acquire the warning level of the abnormal driving state through the fault diagnosis system. The fault diagnosis system can automatically check and monitor the working state of the vehicle (internal transmission system, control system and other parts). After the detection result is obtained, judging whether the detection result is abnormal or not; and if the abnormality exists, classifying the alarm grade according to the detection result.

According to the scheme, after the first vehicle obtains the alarm level of the abnormal driving state, the alarm level is compared with a preset level; if the alarm grade is greater than the preset grade, acquiring first position information and abnormal information of the first vehicle to prepare transmitted abnormal driving information; and if the alarm level is less than or equal to the preset level, not executing any operation. The preset grade is pre-stored in the vehicle, and may be set by the user or by a manufacturer before the vehicle leaves the factory.

It should be noted that, the first vehicle determines whether vehicle information transmission is needed or not according to the level of the warning level of the abnormal driving state, and can effectively screen information, thereby reducing unnecessary information transmission.

in some embodiments, obtaining the first position information of the first vehicle may be embodied as follows: and if the first vehicle detects that the connection with the terminal is established, sending a position acquisition instruction to the terminal, wherein the position acquisition instruction is used for enabling the terminal to acquire position information and sending the position information to the first vehicle, and the first vehicle takes the acquired position information as first position information. The distance between the terminal and the first vehicle is very short, and the position information of the terminal can be equal to the first position information of the first vehicle. The terminal can acquire the position information by means of GPS positioning, navigation software or the like.

in some embodiments, obtaining the first position information of the first vehicle may be embodied as follows: when the first vehicle needs to acquire the first position information of the first vehicle, the first vehicle acquires a plurality of frames of images which are newly stored from the historical driving images, and determines the first position information according to the plurality of frames of images. The first vehicle shoots a scene along the road in the driving process. For example, when the engine of the first vehicle is running, the first vehicle interval time photographs the scene along the road. As another example, when a photographing request of a user is received, the first vehicle photographs the scene along the road.

in some embodiments, the vehicle information transmission method further includes:

104. The first vehicle acquires the current network signal strength.

If the network signal intensity is not less than the preset signal intensity, the first vehicle executes 105;

if the network signal strength is less than the predetermined signal strength, the first vehicle executes 102. Wherein:

105. And sending the abnormal driving information to the Internet of vehicles server.

In the embodiment of the application, the vehicle comprises at least two communication modes: visible light communication and network communication. The network communication may be 2G network communication, 3G network communication, 4G network communication, 5G network communication, or the like, and is not particularly limited. The vehicle networking server is connected with a plurality of vehicles in a network communication mode. The multiple vehicles can send information to the Internet of vehicles server through network communication, the Internet of vehicles server receives the information and then conducts information screening, processing and storing, any vehicle can send the information acquisition request to the Internet of vehicles server, and the Internet of vehicles server receives the information acquisition request and then sends the information to the vehicle with the information acquisition request through the network.

the network signal strength in the scheme represents the success probability and the communication quality of communication. The higher the network signal strength is, the faster the information receiving or sending speed is, that is, the higher the success probability of communication is and the better the communication quality is; the lower the network signal strength, the slower the speed of receiving or sending information, i.e., the lower the probability of success of the communication and the worse the communication quality. The network signal strength of different networks in the same area may be different, and the network signal strength of the same network system in different areas may also be different.

in some embodiments, the obtaining of the current network signal strength by the first vehicle may include: the first vehicle determines the currently connected network system; and acquiring the network signal intensity of the network system. It should be noted that the first vehicle may implement automatic network switching according to the network signal strength in real time, and in general, the first vehicle selects a network system with the highest network signal strength from all network systems supported by the first vehicle, and then establishes a connection with other devices through the network system with the highest network signal strength.

in the embodiment of the application, when the network signal intensity of the network connected with the first vehicle is greater than or equal to the preset signal intensity, the network communication is represented to be capable of timely transmitting information, at the moment, the first vehicle can transmit abnormal running information to the internet-of-vehicles server, and namely the network communication with a wider information transmission range is adopted.

The preset signal intensity is preset in the vehicle, and can be set by a user independently or automatically. The preset network signal strength may be one or more. For example, the preset network signal strength of M region is M, the preset network signal strength of N region is N, and the preset network signal strength of G region and H region is G. Wherein the preset network signal strength can be modified.

In some embodiments, if the network signal strength is not less than the preset signal strength, the sending, by the first vehicle, the abnormal driving information to the internet of vehicles server may include: the method comprises the steps that a first vehicle acquires a geographical position, and acquires preset network signal intensity corresponding to the geographical position; and comparing the network signal intensity with the preset network signal intensity, and if the network signal intensity is greater than or less than the preset signal intensity, sending the abnormal running information to the Internet of vehicles server by the first vehicle.

In the embodiment of the application, when the network signal intensity of a network connected with a first vehicle is smaller than the preset signal intensity, the problem that information transmission delay exists in network communication is shown, at this time, compared with abnormal running information transmission through network communication, the first vehicle converts the abnormal running information into a first digital signal, and then drives an LED lamp of the first vehicle to emit a first optical signal according to the first digital signal.

Specifically, the first digital signal includes two characters of "0" and "1", and the first vehicle driving LED lamp is turned on when the character is "1", and is turned off when the character is "2". For example, the first digital signal is "10100001001", and the first vehicle drives the LED lamp to perform the operation of "switch on/off" to transmit information.

In some embodiments, 103 may include: 1031. 1032 and 1033, wherein:

1031. The first vehicle acquires a failure level of the abnormal traveling information.

The abnormal traveling information in this aspect includes first position information and abnormality information of the first vehicle. In some embodiments, the abnormality information includes an abnormal driving state and an abnormal cause. And the fault grade is used for indicating the possible damage grade caused by the first vehicle in the abnormal running state. The higher the failure level, the greater the danger that the first vehicle may cause in this abnormal running state. The fault level may include zero level, first level, second level, etc., and the number of fault levels is not particularly limited. Wherein a failure level of zero indicates that the first vehicle has no failure problem.

In some embodiments, obtaining the fault level of the abnormal driving information includes: and according to the abnormal reason, searching a fault level corresponding to the abnormal reason from the first mapping relation, and taking the fault level as the fault level of the abnormal driving information. Wherein the first mapping relation is a corresponding relation between the abnormality cause and the fault level. The first mapping relationship is pre-stored in the vehicle, and may be set autonomously by the user, or may be set in another manner.

1032. And acquiring a time interval corresponding to the fault level, wherein the fault level is inversely proportional to the time interval.

In the embodiment of the application, the fault level is inversely proportional to the time interval, which means that the lower the fault level is, the lower the hazard possibly caused at the moment is, the longer the time interval is; the higher the fault level, the greater the hazard that may be created at that time, the shorter the time interval.

in some embodiments, the first vehicle may determine the time interval corresponding to the failure level from the second mapping relationship after acquiring the failure level of the abnormal driving information by previously storing the second mapping relationship between the failure level and the time interval.

1033. The first vehicle-driving LED lamp periodically emits a first light signal according to a first digital signal with a time interval as an emission period.

In the embodiment of the application, after the time interval corresponding to the fault level is acquired, the first vehicle drives the LED lamp to periodically emit the first light signal by using the time interval as an emission period. Wherein the first vehicle generates a first electrical signal from the first digital signal; the LED lamp is driven by the first electric signal to emit a first optical signal according to the first digital signal. The first electric signal is used for driving an LED lamp of the first vehicle to perform on-off operation, so that the LED lamp emits a first optical signal.

For example, assuming that the first digital signal is "10100001001", it takes T seconds for the first vehicle to drive the LED lamp to perform the operation of "switching the switch off and on" once, and the time interval is T seconds. The first vehicle driving LED lamp periodically emits a first light signal according to a first digital signal, and the method comprises the following steps: driving the LED lamp by the first vehicle from 0 to t seconds to perform 'on-off switch' operation once; driving the LED lamp by the first vehicle from T + T to 2T + T seconds to perform 'switching on/off' operation; the first vehicle driving LED lamp performs the operation of "switch on/off switch off" once from 2T +2T to 3T +2T seconds, and the like.

in some embodiments, the first digital signal is embodied as an optical code matrix, and the first vehicle generates the first electrical signal according to the optical code matrix; and driving the LED lamp to emit a first optical signal according to the optical code matrix through the first electric signal.

As can be seen from the above, the first vehicle obtains the time interval of the emitted light signal through the fault level of the abnormal driving information, the time interval is appropriately reduced when the fault level is high, and the time interval is appropriately increased when the fault level is low, so that the emission times of the vehicle information transmission can be ensured, and the timeliness of the vehicle information transmission can be ensured.

referring to fig. 4, fig. 4 is a third flow chart of the vehicle information transmission method according to the embodiment of the present application, which will be described in detail below. In this embodiment, 101 may include 1013, 1014, 1015, where:

In some embodiments, the abnormal driving information includes second position information of the faulty vehicle, and after 101, the method further includes:

Acquiring the distance between the first vehicle and the fault vehicle according to the second position information and the first position information of the first vehicle;

The first vehicle outputs the second position information and the distance.

in this embodiment, the faulty vehicle may be a third vehicle traveling ahead of the first vehicle, or may be a vehicle ahead of the third vehicle.

First, the faulty vehicle is a third vehicle traveling ahead of the first vehicle. Please refer to fig. 5, B in fig. 5₁The vehicle (fault) is a third vehicle, B₂The vehicle being a first vehicle, B₃The vehicle is a second vehicle. B is₁when the vehicle detects that the driving state is the abnormal driving state, B is acquired₁Second position information and abnormal information of the vehicle, then generating abnormal driving information according to the second position information and the abnormal information, and then coding the abnormal driving information to obtain a second digital signal, B₁The vehicle drives the LED lamp to emit a second light signal according to the second digital signal to B₂The vehicle conveys abnormal driving information.

First vehicle B₂Vehicle detection of B₁And when a second optical signal is sent by the vehicle, converting the second optical signal into a second electric signal, converting the second electric signal into a second digital signal, and then decoding the second digital signal to obtain abnormal driving information. B is₂Vehicle repackingCoding the abnormal running information to obtain the first digital signal, and finally B₂the vehicle drives the LED lamp to emit a first optical signal according to the first digital signal to B₃The vehicle conveys abnormal driving information. For example, in some embodiments, after the first vehicle executes 1014, the LED lamp may be directly driven to emit the first light signal in accordance with the second digital signal.

for the first vehicle B₂for vehicles, except for B₁the abnormal running information of the vehicle is transferred to the vehicle B₃in addition to the vehicle, the abnormal traveling information needs to be output to the driver. The method can be specifically realized by the following steps: b is₂The vehicle decodes the second digital signal to obtain abnormal running information, and determines a fault vehicle B according to the abnormal running information₁second position information of the vehicle according to B₁second position information of vehicle and B₂First position information of the vehicle, obtaining B₂Vehicle and B₁Distance between vehicles, output B₁Second position information and distance of the vehicle to notify B₂The driver of the vehicle. The decoding process is the inverse of the encoding process, and is a process of converting a series of signals representing a certain item of information into characters. The decoding process may be implemented by a decoder. The decoder is a multi-input multi-output combinational logic circuit and is divided into a general decoder and a digital display decoder.

Second, the faulty vehicle is also a vehicle traveling ahead of the third vehicle. Referring to FIG. 6, the Bn vehicle in FIG. 6 is the first vehicle, B_n-1The vehicle is a third vehicle running in front of the Bn vehicle, and the Bn-k vehicle is running at B_n-₁The vehicle in front of the vehicle, wherein n is more than 2, and k is more than or equal to 2. The Bn-k vehicles in the embodiment are fault vehicles.

At the same time, Bn₊₁the vehicle continues to transmit the abnormal driving information in the above manner until a transmission termination condition is satisfied.

Note that the first vehicle B_nLight signal sent by vehicle, Bn-k vehicle and B_n-1The information carried by the optical signal sent by the vehicle is the same. In the way, the fault vehicle B_n-kThe abnormal driving information of the vehicle is transmitted by the vehicle after the vehicle is driven, so that the transmission range of the abnormal driving information (particularly, the abnormal driving information is transmitted by emitting light signals through the LED lamp) can be enlarged, and the timeliness of information transmission in the driving process is improved.

In some embodiments, between 1013 and 1014, the method further comprises power amplifying the second electrical signal. The power amplification processing is to increase the output power of the second electrical signal.
