Embodiment approach

[0066] As a preferred implementation manner of the present invention, said judging the current situation of the vehicle includes:

[0067] Whether the vehicle passes through the level crossing between urban tramway and motorway;

[0068] Whether the vehicle passes through the level crossing between the urban tramway and the motorway ahead of the tram;

[0069] Whether the time difference between the arrival of the vehicle and the tram at the level crossing is within the danger zone;

[0070] Whether the vehicle needs to use the car HUD head-up display reminder.

[0071] The present invention also provides an early warning method for vehicles at urban tram level crossings based on vehicle-road coordination. When the threshold is set at a distance from a level crossing, the vehicle information module and the information communication module will transmit the collected vehicles and the position and speed information of the nearby trams to the analysis module; When the tram lev...

Abstract

The invention provides an urban tramcar level crossing automobile early warning system and method based on vehicle-road cooperation. The method comprises the steps that when a vehicle driver selects adestination in a navigation system and a navigation path is determined, a path planning module detects whether the path passes through a level crossing of an urban rail and a motor vehicle road or not; if yes, when the vehicle is driven to a certain distance away from the level crossing, a vehicle information module and an information communication module collect state information of the vehicleand the nearby tramcar respectively and transmit the state information to the analysis module. An analysis module judges and analyzes the situation according to the received information and gives a corresponding instruction. An information prompting module sends out a corresponding passage suggestion or warning prompt after receiving the instruction. According to the invention, reasonable promptsare given according to the condition information of the vehicles and the tramcars before the vehicles pass through the level crossing of the tramcar rail and the motor vehicle lane, so that the vehicles can safely and orderly pass through the level crossing of the urban rail and the motor vehicle lane.

Description

technical field [0001] The present invention relates to the technical field of automobile early warning automation system, in particular to an urban tram level crossing automobile early warning system and method based on vehicle-road coordination. Background technique [0002] Modern trams incorporate new technologies such as modern subways, light rails, and electric-driven vehicles. They are a form of rail transit between highways and subways. Compared with traditional buses, it has the advantages of large passenger capacity, fast operation speed, comfortable riding, and environmental protection; compared with urban subways, modern trams are built on the ground, which greatly shortens the cost, construction period, and operation and maintenance. In recent years, it has gradually become popular in China. [0003] The rapid development of urban transportation is accompanied by new challenges and difficulties. In recent years, with the improvement of people's consumption awa...
