Problems solved by technology

The above-mentioned V2V applications need to operate in an environment where each car is equipped with a vehicle-mounted computer. However, if many vehicles, pedestrians, and even any other moving objects are not equipped with a vehicle-mounted computer, dangerous intersections where there are many vehicles and accidents are likely to cause frequent accidents. problem, affecting the safety of the intersection

Embodiment Construction

[0030] figure 1 It is a schematic diagram illustrating the operation of a roadside detection system according to an exemplary embodiment of the present disclosure.

[0031] Please refer to figure 1 , the roadside detection system 100 includes a roadside infrastructure (roadside infrastructure) 102 . The roadside infrastructure 102 further includes a roadside unit (RSU) 104 and at least one sensor 106 . The sensor 106 can be a sensing device such as a radar 106a, a camera 106b, or a combination thereof. The sensor 106 can be installed on both sides of the road or at a crossroad. The sensor 106 is used to detect at least one object (object) within a detection range, and The detection collects object information of each object at at least two time points t1 and t2. Wherein, the sensor 106 detects objects such as cars, motorcycles, bicycles or pedestrians within the detection range, but the disclosure is not limited thereto.

[0032] The roadside device 104 receives a position...

Abstract

A roadside detection system, a roadside unit and a roadside communication method are provided. The roadside unit (104) receives a positioning signal from a satellite positioning system and obtains roadside latitude and longitude coordinates and an initialization parameter coordinate. The roadside unit (104) receives object information of the object. The roadside unit obtains object latitude and longitude coordinates, an object speed, an object acceleration, an object length, and an object heading / direction based on the roadside latitude and longitude coordinates, the initialization parameter coordinate, and the object information. The roadside unit (104) converts the object latitude and longitude coordinates, the object speed, the object acceleration, the object length, and the object heading / direction into a V2V Basic Safety Message format.

Description

technical field [0001] The disclosure relates to a roadside detection system, a roadside device and a roadside communication method thereof. Background technique [0002] Connected vehicles communication technology can be used for active road safety applications. In the in-vehicle network environment, many applications need to broadcast the vehicle status through the standard basic safety message (Basic Safety Message, BSM), such as Intersection Movement Assist (IMA), Left Turn Assist (LTA) ), lane change warning (Lane change warning, LCW), forward collision warning (ForwardCollision Warning, FCW), or electronic brake light warning (Electronic Emergency Brake Light, EEBL), etc. Networked vehicle communication technology allows one's own car to communicate or communicate with other vehicle equipment or roadside devices to exchange basic safety information to avoid accidents. Vehicle-to-vehicle communication modes include Vehicle-to-Vehicle (V2V), Vehicle-to-Roadside (V2R) a...
