Referring to fig. 1-2, fig. 1 is a vehicle travel assistance system 100 provided by the present application, where the vehicle travel assistance system 100 includes an on-board device 20 disposed on a vehicle 10 and a terminal device 30 communicatively connected to the on-board device 20. The terminal device 30 is connected to the traffic light 40 for communication, and is used for acquiring the status information of the traffic light 40. Therefore, the traffic light command information on the corresponding traffic road is obtained through the state information, and if the indicator light of the corresponding lane is a red light, a green light or a yellow light, the traffic light command information is obtained.
When a driver drives the vehicle 10 to run on a road, if the traffic indicator 40 is in front of the road and the driving view of the driver is blocked, the vehicle-mounted device 20 sends a request for the state information of the traffic indicator 40 to the terminal device 30 to acquire the state information of the traffic indicator 40, so that the driver knows that the indicator of the corresponding lane is a red light, a green light or a yellow light, and unnecessary driving violation is avoided.

In some embodiments, the obtaining the position information of the vehicle includes:
acquiring positioning information of a positioning device, wherein the positioning device is in communication connection with the vehicle-mounted equipment;
and acquiring the position information according to the positioning information.
For example, the positioning device may be a GPS positioning device or a beidou positioning device, and the positioning device obtains positioning information corresponding to the positioning device and uses the positioning information as the position information of the vehicle 20. The positioning device may be integrated in the vehicle-mounted device 20, or may be independent of the vehicle-mounted device 20, which is not limited herein.
Step S2: detecting whether a traffic light is present at a first distance from the vehicle in front of the vehicle according to the position information.
Referring to fig. 4, in some embodiments, the detecting whether a traffic light is present in front of the vehicle at a first distance from the vehicle according to the position information includes:
step S21: judging whether the position in front of the vehicle driving road is an intersection at the first distance from the vehicle according to the position information;
step S22: if the position, which is in front of the vehicle driving road and is away from the vehicle by the first distance, is an intersection, acquiring intersection media information corresponding to the intersection, wherein the intersection media information at least comprises one of intersection image information or intersection video information;
step S23: and detecting whether the traffic indicator lamp exists at the intersection or not according to the intersection media information.
Illustratively, an area map of an area where the vehicle 10 travels is downloaded in the in-vehicle device 20, and it is determined whether there is an intersection at a first distance from the vehicle 10 in front of the vehicle traveling direction, which may be set as needed, e.g., 10m, 20m, 50m, based on the area map and the position information of the vehicle 10.
If the position in front of the vehicle driving road and the distance from the vehicle is the intersection, the image information or the video information of the intersection is acquired by the camera device arranged in the vehicle 10, so as to analyze whether the traffic indicator lamp 40 is arranged at the intersection or not according to the image information or the video information of the intersection.
Step S3: and if the traffic indicator lamp exists at the intersection, acquiring first media information at a second distance away from the vehicle in front of the vehicle, wherein the first media information at least comprises one of image information or video information.
If the traffic light 40 exists at the intersection, first media information at a second distance from the vehicle 10 in front of the vehicle 10 is acquired through a camera device arranged in the vehicle 10, wherein the first media information at least comprises one of image information or video information, so as to judge whether a driving view in front of the vehicle 10 is blocked or not according to the first media information.
Step S4: and judging whether the driving view in front of the vehicle is blocked or not according to the first media information.
Referring to fig. 5, in some embodiments, the determining whether the driving view in front of the vehicle is blocked according to the first media information includes:
step S41: and judging whether a preset model vehicle exists in the position, away from the vehicle by the second distance, in front of the vehicle according to the first media information.
As shown in fig. 6, step S41 includes:
step S411: acquiring vehicle characteristic data according to the first media information;

In some embodiments, if the feature matching degree does not exceed the matching degree threshold, the process ends.
Step S42: and if the preset type vehicle exists in the position, away from the vehicle, of the second distance, in front of the vehicle, it is judged that the driving view in front of the vehicle is blocked.
For example, during the driving process of the vehicle 10, the driving sight line is easily blocked by a large vehicle driving at a preset second distance in front, so that the traffic signal lamp 40 cannot be seen clearly to cause traffic violation, wherein the second distance can be set as required, such as 1m, 1.5m, and 2 m.
Therefore, when the driving sight line is blocked, the first media information at the second distance from the vehicle 10 in front is acquired, and the first media information may be video information of the environment at the second distance or image information of the environment at the second distance. Whether the current first media information has vehicle characteristic data is analyzed through the acquired first media information, and the vehicle characteristic data can be the overall appearance shape and size of the vehicle, the tail shape and size of the vehicle and the like. If the first media information includes vehicle feature data, vehicle feature data is acquired, the acquired vehicle feature data is matched with sample vehicle feature data stored in a database in the vehicle-mounted device 20, and if the vehicle feature matching degree exceeds a matching degree threshold, it is determined that a vehicle of the preset model, that is, a large vehicle, exists in front of the vehicle 10 at the second distance from the vehicle 10, that is, it is determined that there is a possibility of a traffic rule violation if the vehicle continues to travel along with the preset vehicle.
Wherein, the threshold of the matching degree can be set according to the requirement, such as 80%, 90% or 99%.
Step S5: and if the driving view in front of the vehicle is blocked, sending a state request of the traffic indicator lamp to a terminal device in communication connection with the vehicle-mounted device.
If the driving view in front of the vehicle 10 is judged to be blocked, the vehicle-mounted device 20 sends a state request of the traffic indicator lamp 40 to the terminal device 30 which is in communication connection with the vehicle-mounted device 20, so that the terminal device 30 responds to the state information of the traffic indicator lamp 40 sent by the state request.
Step S6: and receiving the state information of the traffic indicator light sent by the terminal equipment in response to the state request.
The vehicle-mounted device 20 receives the state information of the traffic light 40 sent by the terminal device 30 in response to the state request, so as to know whether the current road indicated by the current traffic light 40 can pass or not according to the state information of the traffic light 40.
