Road marking coating for automatic driving vehicle radar system recognition and preparation method thereof

Abstract

The invention relates to a road marking coating recognized by a radar system of an automatic driving vehicle and a preparation method thereof. The road marking coating is characterized in that it comprises 2-20 parts of an adhesive, 5-25 parts of a resin material, 0.1-2 parts of peroxide curing agent, 1-5 parts of epoxy curing agent, 0-5 parts of reactive diluent, 10-25 parts of conductive additive, 10-35 parts of conductive mica sheet, 10 parts of conductive silver-coated glass powder ‑30 parts, conduction accelerator 1‑2 parts, dispersant 0.5‑2 parts. The road marking coating can be more accurately recognized by the automatic driving system, thereby better identifying road conditions, more accurately determining the position of the car, and making automatic driving safer and more reliable.

Description

technical field [0001] The invention relates to a road marking coating, in particular to a road marking coating recognized by a radar system of an automatic driving vehicle and a preparation method thereof. Background technique [0002] The automatic driving system is an important function of future car configuration, and it is also a great progress in the development of human civilization. The existing automatic driving system needs to ensure that the vehicle will not deviate from the lane by recognizing the signs (lane signs) / marking lines (traffic markings) on the road, and realize automatic turning driving. Once the signs / marking lines on the road If there are blurred or snow-covered situations that hinder the recognition of the automatic driving system, the automatic driving system may lose its accurate positioning ability and even cause traffic accidents. It can be seen that the importance of clear signs / marking lines to the automatic driving system . [0003] Existi...

AI Technical Summary

Problems solved by technology

[0003] Existing signs / marking lines are generally made of hot-melt resin and colorant (for distinction), and the production of signs and marking lines is completed by delimiting and coating the raw materials on the road; the main component of the raw material is hot-melt resin. It has been rubbed for a long time, so it is easy to appear blurred, damaged, peeled off, covered with stains and other phenomena after long-term use. It will lead to system failure, which will seriously affect driving safety; at the same time, signs / markings that are not recognized by radar (including millimeter-wave radar and lidar) are very unsafe. For example, cameras may not be able to "see" signs / marks in snowy and rainy weather Marking the line, the chance of "derailment" is greatly improved
