Detailed Description
The application provides an information interaction method and system between vehicles based on an internet of vehicles, which are used for reducing the risk of sudden traffic accidents.
It should be noted that the information interaction method provided by the present application is applied to a first vehicle, a second vehicle and a cloud sharing service platform, wherein the first vehicle and the second vehicle are respectively connected to the cloud sharing service platform.
Referring to fig. 1, fig. 1 is a diagram illustrating an embodiment of a method for information interaction between vehicles based on a car networking, where the method includes:
101. when a first vehicle is in a running state, a first vehicle-mounted terminal broadcasts first broadcast information in real time, the first vehicle-mounted terminal is a vehicle-mounted terminal of the first vehicle, and the first broadcast information is used for the first vehicle-mounted terminal to find a second vehicle in a preset range in real time;
the first vehicle-mounted terminal searches for a second vehicle located in a preset range in real time in a real-time broadcast communication mode. The preset range is a circular range formed by taking the position of the first vehicle as the center of a circle and taking a preset distance as a radius. For example: when the preset distance is 10 meters, the preset range is a circular range taking the position coordinate of the first vehicle as the center of a circle and taking 10 meters as the radius.
102. The first vehicle-mounted terminal receives first response information fed back by a second vehicle-mounted terminal of the second vehicle, and the first vehicle-mounted terminal acquires the vehicle identity information of the second vehicle through the first response information;
when the second vehicle-mounted terminal within the preset range receives the first broadcast information sent by the first vehicle-mounted terminal, the second vehicle-mounted terminal feeds back the first response information to the first vehicle-mounted terminal. The first response information carries vehicle identity information of the second vehicle, and the vehicle identity information can be license plate number information of the second vehicle.
For example: after the first vehicle-mounted terminal a sends the first broadcast information, B, C, D are located at the second vehicle-mounted terminal within the preset range of the first vehicle-mounted terminal, and B, C, D receives the first broadcast information, at this time, the second vehicle-mounted terminal B, C, D feeds back the first response information to the first vehicle-mounted terminal a, and the first vehicle-mounted terminal a obtains the identity information of B, C, D, that is, the license plate number information of B, C, D, through the first response information.
103. When the first vehicle-mounted terminal determines that the first vehicle runs abnormally according to the real-time running state information of the first vehicle, the first vehicle-mounted terminal generates danger information;
when the first vehicle is in a running state, the sensor of the first vehicle continuously acquires the vehicle real-time running state information of the first vehicle, such as vehicle speed, vehicle mass, running direction and the like. And transmitting the vehicle driving state information to the first vehicle-mounted terminal. And when the first vehicle-mounted terminal determines that the first vehicle runs abnormally according to the real-time running state information, the first vehicle-mounted terminal generates danger information.
For example: during the running process of the first vehicle a, the sensor of the first vehicle a detects that one tire pressure of the first vehicle a is unstable, and there is a risk of tire burst, then the sensor of the first vehicle a sends the tire pressure information to the first vehicle-mounted terminal, and the first vehicle-mounted terminal generates danger information when determining that the first vehicle a is in abnormal running according to the real-time running state information.
104. The first vehicle-mounted terminal sends the vehicle identity information of the second vehicle to a cloud sharing service platform, so that the cloud sharing service platform determines the second vehicle-mounted terminal through the vehicle identity information;
the cloud sharing service platform is responsible for forwarding and receiving data. Before the cloud sharing service platform forwards and receives data, two communication parties must be determined first. The first vehicle-mounted terminal sends the identity information of the second vehicle to the cloud sharing service platform, so that the cloud sharing service platform determines the second vehicle-mounted terminal communicated with the first vehicle-mounted terminal through the identity information of the second vehicle, namely the first vehicle-mounted terminal establishes an information interaction mode with the second vehicle-mounted terminal through the cloud sharing service platform.
Only if the cloud sharing service platform determines a second vehicle-mounted terminal communicated with the first vehicle-mounted terminal according to the vehicle identity information of the second vehicle, the cloud sharing service platform can accurately forward the information sent by the first vehicle-mounted terminal to the second vehicle-mounted terminal.
For example: the first vehicle-mounted terminal a sends the identity information of the second vehicle-mounted terminal B, C, D to the cloud sharing service platform, and at this time, the cloud sharing service platform establishes a first communication channel with the first vehicle-mounted terminal a and a second communication channel with the second vehicle-mounted terminal B, C, D, respectively. When a needs to send B, C, D the data only needs to be sent to the cloud sharing server platform through the first communication channel, and the cloud sharing server platform forwards the data to the second on-board terminal B, C, D through the second communication channel.
105. The first vehicle-mounted terminal sends the dangerous information to the cloud sharing service platform, so that the cloud sharing service platform sends the dangerous information to the second vehicle-mounted terminal, and the second vehicle-mounted terminal controls the second vehicle to run or send out driving reminding information according to a preset mode according to the dangerous information.
The first vehicle-mounted terminal sends the dangerous information to the cloud sharing service platform, and the cloud sharing service platform forwards the dangerous information to the second vehicle-mounted terminal, so that the second vehicle-mounted terminal controls the second vehicle to run or send out driving reminding information according to a preset mode according to the dangerous information. The preset running mode can be deceleration running or braking. When the second vehicle-mounted terminal receives the danger information, the second vehicle-mounted terminal controls the second vehicle to brake or decelerate according to the danger information so as to keep a sufficient safe distance with the first vehicle, or the second vehicle-mounted terminal sends out a driving prompt according to the danger information, so that a driver driving the second vehicle can make a preparation measure in advance and keep a sufficient safe distance with the first vehicle. After the second vehicle-mounted terminal sends out a driving prompt according to the danger information, the second vehicle-mounted terminal controls the second vehicle to run according to a preset mode when the second vehicle-mounted terminal does not detect that the second vehicle runs according to the preset mode within a preset time, so that the second vehicle and the first vehicle keep a sufficient safe distance.
For example: the first vehicle-mounted terminal A sends the information of tire burst to the cloud sharing service platform, the cloud sharing service platform forwards the information to the second vehicle-mounted terminal B of the second vehicle B running behind the first vehicle A, at the moment, the second vehicle-mounted terminal B controls the second vehicle B to run at a reduced speed or brake, or the second vehicle-mounted terminal B gives an alarm, so that the owner of the second vehicle B can make a preparation measure in advance, and the second vehicle B and the first vehicle A keep a sufficient safety distance.
In this embodiment, when the first vehicle-mounted terminal predicts that the first vehicle is in an abnormal driving state which may cause a traffic accident according to a real-time driving state of the first vehicle, and needs to enable a second vehicle near the first vehicle to avoid danger urgently, the first vehicle-mounted terminal sends danger information to the second vehicle-mounted terminal of the second vehicle in real time through the cloud sharing service platform, so that information interaction between the vehicles is realized, the second vehicle can take corresponding measures in time according to the danger information, and therefore the first vehicle and the second vehicle have a sufficient safety distance, and the risk of occurrence of the sudden traffic accident is effectively reduced.

201. when a first vehicle is in a running state, a first vehicle-mounted terminal broadcasts first broadcast information in real time, the first vehicle-mounted terminal is a vehicle-mounted terminal of the first vehicle, and the first broadcast information is used for the first vehicle-mounted terminal to find a second vehicle in a preset range in real time;
202. the first vehicle-mounted terminal receives first response information fed back by a second vehicle-mounted terminal of the second vehicle, and the first vehicle-mounted terminal acquires the vehicle identity information of the second vehicle through the first response information;
203. The first vehicle-mounted terminal broadcasts second broadcast information in real time, and the second broadcast information is used for the first vehicle-mounted terminal to find a third vehicle in a preset range in real time;
optionally, the first vehicle-mounted terminal searches for a third vehicle located within the preset range in real time in a real-time broadcast communication mode. The preset range of the second broadcast information is a circular range formed by taking the position of the first vehicle as a circle center and taking a preset distance as a radius.
204. The first vehicle-mounted terminal receives second response information fed back by a third vehicle-mounted terminal of a third vehicle, and the first vehicle-mounted terminal acquires the vehicle identity information of the third vehicle through the second response information;
optionally, when the third vehicle-mounted terminal within the preset range receives the second broadcast information sent by the first vehicle-mounted terminal, the third vehicle-mounted terminal may all feed back the second response information to the first vehicle-mounted terminal. The second response information carries vehicle identity information of the third vehicle, and the vehicle identity information may be license plate number information of the third vehicle.
For example: after the first vehicle-mounted terminal a sends the second broadcast information, B, C, D are located at third vehicle-mounted terminals within a preset range of the first vehicle-mounted terminal, and B, C, D all receive the second broadcast information, at this time, the third vehicle-mounted terminal B, C, D feeds back second response information to the first vehicle-mounted terminal a, and the first vehicle-mounted terminal a obtains B, C, D identity information, that is, B, C, D license plate number information, through the second response information.
205. When the first vehicle-mounted terminal determines that the first vehicle runs abnormally according to the real-time running state information of the first vehicle, the first vehicle-mounted terminal generates danger information;
step 205 in this embodiment is similar to step 103 in the embodiment shown in fig. 1, and detailed description thereof is omitted here.
206. The first vehicle-mounted terminal determines that the third vehicle is not currently in a preset range of the first vehicle;
optionally, when the first vehicle-mounted terminal determines that the first vehicle is running abnormally according to the real-time running state information of the first vehicle, the first vehicle-mounted terminal sends third broadcast information, where the third broadcast information carries identity information of a third vehicle, and the third broadcast information is used to determine that the third vehicle is not currently within a preset range of the first vehicle. And in the preset time, the first vehicle-mounted terminal does not receive the third response information fed back by the third vehicle, and the first vehicle-mounted terminal determines that the third vehicle is not currently in the preset range of the first vehicle at the moment.
207. The first vehicle-mounted terminal deletes the vehicle identity information of the third vehicle;
optionally, since the third vehicle has deviated from the preset range, that is, the distance between the third vehicle and the first vehicle is greater than or equal to the safe distance, when the first vehicle is in abnormal driving, the third vehicle does not need to be prepared in advance, so that it is not necessary to send dangerous information to the third vehicle, and the first vehicle-mounted terminal deletes the vehicle identity information of the third vehicle.
208. The method comprises the steps that a first vehicle-mounted terminal determines that a second vehicle is currently located in a preset range of a first vehicle;
when the first vehicle-mounted terminal determines that the first vehicle is abnormally driven according to the real-time driving state information of the first vehicle, the first vehicle-mounted terminal sends fourth broadcast information, the fourth broadcast information carries identity information of the second vehicle, and the fourth broadcast information is used for determining that the second vehicle is currently located within a preset range of the first vehicle. And in the preset time, the first vehicle-mounted terminal receives fourth response information fed back by the second vehicle, and the first vehicle-mounted terminal determines that the second vehicle is currently in the preset range of the first vehicle.
209. The first vehicle-mounted terminal sends the vehicle identity information of the second vehicle within the preset range to the cloud sharing service platform, so that the cloud sharing service platform determines the second vehicle-mounted terminal according to the vehicle identity information;
the first vehicle-mounted terminal sends the vehicle identity information of the second vehicle within the preset range to the cloud sharing service platform, so that the cloud sharing service platform determines the second vehicle-mounted terminal according to the vehicle identity information of the second vehicle.
210. The first vehicle-mounted terminal sends the dangerous information to the cloud sharing service platform, so that the cloud sharing service platform sends the dangerous information to the second vehicle-mounted terminal, and the second vehicle-mounted terminal controls the second vehicle to run or send out driving reminding information according to a preset mode according to the dangerous information.
Step 210 in this embodiment is similar to step 105 in the embodiment shown in fig. 1, and detailed description thereof is omitted here.
In this embodiment, when the first vehicle-mounted terminal predicts that the first vehicle is in an abnormal driving state that may cause a traffic accident according to a real-time driving state of the first vehicle, the first vehicle-mounted terminal determines that the third vehicle is not within a preset range of the first vehicle, the first vehicle-mounted terminal deletes the identity information of the third vehicle, and determines that the second vehicle is within the preset range of the first vehicle-mounted terminal at the time, the first vehicle-mounted terminal only sends the vehicle identity information of the second vehicle to the cloud sharing service platform, and the cloud sharing service platform only forwards the danger information to the second vehicle and does not forward the danger information to the third vehicle. When the first vehicle is in an abnormal running state, the first vehicle-mounted server only informs the second vehicle which is in the preset range of the first vehicle at the moment, so that the second vehicle can make preparation measures in advance, and does not inform the third vehicle which is not in the preset range, thereby not influencing the normal running of the third vehicle outside the preset range and reducing the possibility of traffic jam.
