Further, the first server may store a history of travel paths of the vehicle to which the first vehicle-mounted terminal belongs.
The second option is: in the historical driving process of the first vehicle-mounted terminal, the first vehicle-mounted terminal realizes positioning through the GPS function of the first vehicle-mounted terminal and transmits the positioning information to the second server, so that the second server obtains the historical driving path of the vehicle to which the first vehicle-mounted terminal belongs. Further, the second server may store a history of travel paths of the vehicle to which the first vehicle-mounted terminal belongs. Further, the second server may transmit the history travel path of the vehicle to which the first vehicle-mounted terminal belongs to the first server.
Alternatively, the second server may transmit the historical travel path of the vehicle to which the first vehicle-mounted terminal belongs to the first server, including: the first server sends a request message to the second server, wherein the request message is used for requesting to acquire the historical driving path of the vehicle to which the first vehicle-mounted terminal belongs. The second server sends a response message to the first server, the response message comprising: and the historical travel path of the vehicle to which the first vehicle-mounted terminal belongs. Or the second server actively sends the historical travel path of the vehicle to which the first vehicle-mounted terminal belongs to the first server. The embodiment of the present application does not limit this.
Further, the first server obtains the traffic information sent by the second vehicle-mounted terminal, and the traffic information includes: the first server acquires the road condition information sent by the second vehicle-mounted terminal in a voice mode.
As described above, the traffic information includes: the position of the special road condition. For example: the road condition information is as follows: and if the road section A has a traffic accident, the road section A is the position of the special road condition. Or, the road B has many vehicles and is likely to have traffic jam, and the road B is the location of the special road condition.

To sum up, an embodiment of the present application provides a method for acquiring traffic information, including: the first server acquires a historical driving path of a vehicle to which the first vehicle-mounted terminal belongs, and acquires road condition information sent by the second vehicle-mounted terminal, wherein the road condition information comprises: the position of the special road condition. The first server judges whether the position belongs to the historical driving path. And if the first server determines that the position belongs to the historical driving path, the first server broadcasts the road condition information to the first vehicle-mounted terminal. Therefore, the driver does not need to manually acquire the road condition information, but the first server actively broadcasts the road condition information to the first vehicle-mounted terminal, and therefore the query efficiency of the road condition information can be improved.
Example two
Optionally, fig. 3 is a flowchart of a method for acquiring road condition information according to another embodiment of the present application, and as shown in fig. 3, step S23 includes:
step S31: and if the first server determines that the position belongs to the historical driving path, the first server acquires the current position of the first vehicle-mounted terminal.
Wherein, first server obtains the current position of first on-vehicle terminal, includes: the first server sends a request message to the first vehicle-mounted terminal, and the request message requests to acquire the current position of the first vehicle-mounted terminal. The first vehicle-mounted terminal acquires the current position of the vehicle through the GPS function and sends the current position to the first server.
Or the first server does not need to send the request message to the first vehicle-mounted terminal. The first vehicle-mounted terminal actively acquires the current position of the vehicle through the GPS function and sends the current position to the first server.
Step S32: and the first server judges whether the vehicle to which the first vehicle-mounted terminal belongs enters the historical driving path or not according to the current position.
For example: if the first server determines that the distance between the current position and any position in the historical driving path is smaller than or equal to the preset distance, the first server determines that the vehicle to which the first vehicle-mounted terminal belongs is about to enter the historical driving path. If the first server determines that the distances between the current position and all the positions in the historical driving path are larger than the preset distance, the first server determines that the vehicle to which the first vehicle-mounted terminal belongs does not need to enter the historical driving path.
Step S33: and if the first server determines that the vehicle to which the first vehicle-mounted terminal belongs is about to enter the historical driving path, the first server broadcasts the road condition information to the first vehicle-mounted terminal.
As described above, the first server may broadcast the traffic information to the first vehicle-mounted terminal in a voice manner.
The embodiment of the application provides a method for acquiring road condition information, which comprises the following steps: the first server acquires the current position of the first vehicle-mounted terminal. The first server judges whether the vehicle to which the first vehicle-mounted terminal belongs enters the historical driving path or not according to the current position. And if the first server determines that the vehicle to which the first vehicle-mounted terminal belongs is about to enter the historical driving path, the first server broadcasts the road condition information to the first vehicle-mounted terminal. That is, if the first server determines that the vehicle to which the first vehicle-mounted terminal belongs does not intend to enter the historical driving path, the first server does not need to broadcast the road condition information to the first vehicle-mounted terminal, so that the overhead of the first server can be saved.
EXAMPLE III
Optionally, fig. 4 is a flowchart of a method for acquiring road condition information according to another embodiment of the present application, and as shown in fig. 4, step S23 includes:
step S41: and if the first server determines that the position belongs to the historical driving path, the first server determines the current time information and the time information corresponding to the historical driving path.
Step S42: and the first server judges whether the vehicle to which the first vehicle-mounted terminal belongs enters the historical driving path or not according to the current time information and the time information corresponding to the historical driving path.
Specifically, if the current time information is within the time information corresponding to the historical driving path, the first server determines that the vehicle to which the first vehicle-mounted terminal belongs is required to enter the historical driving path, and otherwise, the first server determines that the vehicle to which the first vehicle-mounted terminal belongs is not required to enter the historical driving path. For example, the current time information is 8:10 in the morning. The time information corresponding to the historical driving path is 8:00 in the morning to 8 in the morning: 30. in this case, the first server determines that the vehicle to which the first in-vehicle terminal belongs is to enter the history travel path.
Step S43: and if the first server determines that the vehicle to which the first vehicle-mounted terminal belongs is about to enter the historical driving path, the first server broadcasts the road condition information to the first vehicle-mounted terminal.
As described above, the first server may broadcast the traffic information to the first vehicle-mounted terminal in a voice manner.
The embodiment of the application provides a method for acquiring road condition information, which comprises the following steps: and the first server determines the current time information and the time information corresponding to the historical driving path. And the first server judges whether the vehicle to which the first vehicle-mounted terminal belongs enters the historical driving path or not according to the current time information and the time information corresponding to the historical driving path. And if the first server determines that the vehicle to which the first vehicle-mounted terminal belongs is about to enter the historical driving path, the first server broadcasts the road condition information to the first vehicle-mounted terminal. That is, if the first server determines that the vehicle to which the first vehicle-mounted terminal belongs does not intend to enter the historical driving path, the first server does not need to broadcast the road condition information to the first vehicle-mounted terminal, so that the overhead of the first server can be saved.
Example four
On the basis of any of the above embodiments, further, as shown in fig. 5, a flowchart of a method for acquiring traffic information according to another embodiment of the present application is shown, before the step S22, the method for acquiring traffic information further includes:
step S51: the first server receives an inquiry request message sent by the first vehicle-mounted terminal in a voice mode, wherein the inquiry request message is used for requesting to inquire road condition information in a historical driving path.
It should be noted that, in this way, after the first server receives the query request message sent by the first vehicle-mounted terminal, the first server determines whether the location belongs to the historical travel path. Of course, it is not excluded that the first vehicle-mounted terminal does not need to send the query request message to the first server, but the first server actively determines whether the position belongs to the historical driving path.
In short, when the first server receives the query request message sent by the first vehicle-mounted terminal in a voice mode, whether the position belongs to the historical driving path or not is judged. That is, when the first server does not receive the inquiry request message transmitted by the first in-vehicle terminal, the first server does not need to determine whether the position belongs to the historical travel path. Thereby the overhead of the first server can be saved. On the contrary, the first vehicle-mounted terminal does not need to send the query request message to the first server, but the first server actively judges whether the position belongs to the historical driving path, so that the query efficiency of the road condition information can be improved.
EXAMPLE five
On the basis of any of the above embodiments, further, as shown in fig. 6, fig. 6 is a flowchart of a method for acquiring road condition information according to another embodiment of the present application, and as shown in fig. 6, the step S23 includes:

Step S62: and the first server broadcasts the road condition information according to the emergency level.
In an optional manner, the broadcasting of the traffic information by the first server according to the emergency level includes: the first server determines the broadcasting times of the road condition information according to the emergency level; and the first server broadcasts the road condition information according to the broadcasting times. Optionally, the emergency level of the traffic information is proportional to the number of times of broadcasting.
For example: when a traffic accident occurs in a certain road section, the highest emergency level is determined, and the corresponding broadcast times are 3. When a traffic jam exists in a certain road section, the emergency level is determined to be high, and the corresponding broadcast times are 2.
Optionally, the first server stores at least one traffic information and a corresponding emergency level in advance.
Optionally, the first server stores a corresponding relationship between the emergency level and the broadcast number in advance. For example: the corresponding relationship is shown in table 1:
TABLE 1
| Indexing of urgency levels | Number of times of broadcast |
| 1 | 3 |
| 2 | 2 |
| 3 | 1 |
Wherein the smaller the index of the urgency level, the higher the urgency level.
In another optional mode, the broadcasting, by the first server, the traffic information according to the emergency level includes: the first server determines the broadcasting frequency of the road condition information within a preset time period according to the emergency level; and the first server broadcasts the road condition information according to the broadcasting frequency. Optionally, the emergency level of the traffic information is proportional to the broadcast frequency.
In summary, in the embodiment of the present application, the first server determines the urgency level of the traffic information. And the first server broadcasts the road condition information according to the emergency level. For the traffic information with higher emergency level, the server can broadcast the traffic information as soon as possible, thereby further improving the query efficiency of the traffic information.
