AI Technical Summary

Technical Problem

In the prior art, the reflectivity of the road surface marking to radar signals is low, making it difficult to effectively assist the lateral positioning and control of the vehicle.

Method used

A pavement marking is designed to embed dihedral angular reflectors or other properly oriented directional reflectors that reflect the radar signal and are arranged near lane lines or road boundaries to improve the reflectivity of the radar signal.

Benefits of technology

By increasing the reflectivity of road markings to radar signals, more efficient and accurate assistance for vehicle lateral positioning and control is achieved, and the safety and stability of the vehicle during driving is enhanced.

Abstract

The present disclosure generally relates to: (1) road marking in which a radar reflective dihedral corner reflector or other suitably oriented directional reflector capable of reflecting radar signals is embedded; (2) arranging radar reflection road surface marks on the driving surface; (3) manufacturing the road surface mark and mounting the road surface mark on a driving surface; (4) a radar transceiver on or within the vehicle for sensing radar reflective road markings and measuring the distance between the vehicle and the markings; (5) a vehicle equipped with such a radar transceiver; and (6) a method of controlling or assisting in the lateral steering or positioning of a vehicle on a driving surface (e.g., a road or a lane of a road) based on the detection of radar-reflected road markings on the driving surface (e.g., along or near a road or lane boundary).
