Problems solved by technology

[0005] The purpose of the present invention is to provide a pedestrian-vehicle collision avoidance warning system and method based on vehicle-road coordination, which can provide pedestrian traffic warning information for vehicles passing through the road construction area, and avoid traffic accidents caused by the driver's line of sight being blocked. In the above-mentioned background technology, because the road construction area blocks the driver's line of sight, it is easy to cause a technical problem of traffic accidents

Embodiment 1

[0066] Such as figure 1 As shown, Embodiment 1 of the present invention provides a pedestrian-vehicle collision avoidance warning system based on vehicle-road coordination. The system includes a pedestrian information collection module, an obstruction position information collection module, a collision avoidance information processing module, and a vehicle control module;

[0067] The pedestrian information collection module is used to collect pedestrian position information and pedestrian speed information, and send the pedestrian position information and pedestrian speed information to the collision avoidance information processing module;

[0068] The block position information collection module is used to collect block position information, and send the block position information to the collision avoidance information processing module;

[0069] The collision avoidance information processing module is used to receive the pedestrian position information, pedestrian speed in...

Embodiment 2

[0081] Such as figure 2 As shown, Embodiment 2 of the present invention provides another pedestrian-vehicle collision avoidance warning system for construction roads based on vehicle-road coordination.

[0082] In this embodiment, the radar monitor is used as a pedestrian information acquisition module and an obstruction position information acquisition module to monitor whether there are pedestrians crossing the road. Once a pedestrian crossing the street is found, the detection radar acquires the pedestrian's position coordinates, speed and occlusion point in real time coordinates of the location and transmit the above information to the on-board controller.

[0083] As an early warning information processing module, the on-board controller is used to obtain the current position coordinates and speed of the conflicting vehicle in real time and receive the collected information sent by the above-mentioned radar monitor, process the obtained information and collected informat...

Embodiment 3

[0093] Such as Figure 3 to Figure 4 As shown, Embodiment 3 of the present invention provides a method for performing collision avoidance warning by using the system as described in Embodiment 2. The method includes the following process steps:

[0094] Step S1: When a pedestrian crossing the street appears, the radar detector activates the central controller and starts to collect the coordinates of the pedestrian's position (X 人 , Y 人 ), pedestrian moving speed v 人 and the position coordinates of the line-of-sight occlusion point (X 盲 , Y 盲 ). In this embodiment, the position of the radar detector is taken as the coordinate origin (X 0 ,Y 0 ).

[0095] Step S2: After the central controller is activated, it starts to receive the information collected by the radar detector, and sends the collected information of pedestrians and occluded points to the vehicle-mounted receiver of the conflicting vehicle.

[0096] Step S3, after the on-board receiver of the vehicle receive...

Abstract

The invention discloses a construction road pedestrian and vehicle collision avoidance early warning system based on vehicle-road collaboration and a construction road pedestrian and vehicle collisionavoidance early warning method based on vehicle-road collaboration. The system comprises a pedestrian information acquisition module which is used for acquiring the pedestrian position information and the pedestrian speed information, an occlusion position information acquisition module which is used for acquiring the occlusion position information, a collision avoidance information processing module which is used for judging transmitting of the early warning information according to the pedestrian position information, the pedestrian speed information, the collision avoidance information, the vehicle position information and the vehicle speed information, and a vehicle-mounted control module which is used for acquiring the vehicle information and receiving the early warning information.A driver blind area range model is constructed according to the pedestrian position information, the speed information, the occlusion position information and the vehicle position and speed information so as to determine whether the pedestrian is in the driver blind area range and judge transmitting of the early warning information. The pedestrian passing early warning information is provided forthe vehicle passing the road construction area so that the traffic accident caused by driver sight shielding can be avoided and the traffic safety can be enhanced.

Description

technical field [0001] The invention relates to the technical field of traffic operation control, in particular to a pedestrian-vehicle collision avoidance warning system and method on construction roads based on vehicle-road coordination. Background technique [0002] The existence of road construction areas often easily induces traffic safety problems. Especially on road sections that require long-term operations, baffles will be erected around the construction area to ensure the safety of workers. However, when the vehicle passes through the construction area, the existence of these baffles will undoubtedly block the driver's line of sight, resulting in a blind spot in the field of vision. At this time, if a pedestrian in the blind spot crosses the road from the side of the construction area, since the driver cannot observe the pedestrian and take timely measures to avoid collision, it is very likely to cause a traffic accident. [0003] At present, the development of v...
