Tail light adaptive control method and system based on millimeter wave radar

By using a taillight adaptive control system based on millimeter-wave radar, three-dimensional point cloud data is generated and a trapezoidal model is used to assess risks and adjust the taillight light signal. This solves the problem that traditional taillights cannot actively sense the rear environment, achieves accurate adaptive warnings, and improves driving safety.

AI Technical Summary

Technical Problem

Traditional taillight control systems cannot sense the traffic environment behind, resulting in an inability to provide proactive warnings. Furthermore, the existing risk assessment logic is simplistic, leading to false alarms or missed alarms, and failing to achieve accurate warnings through hierarchical adaptation.

Method used

Signal processing based on millimeter-wave radar generates three-dimensional point cloud data. Rear-end collision risks are assessed through spatial clustering and ladder modeling, and taillight intensity or flashing frequency is adjusted to achieve adaptive warning.

Benefits of technology

It improves the ability to proactively warn vehicles behind, ensures that warning signals match the risk level, reduces false alarms and missed alarms, and enhances driving safety.

Abstract

The application provides a tail lamp adaptive control method and system based on millimeter wave radar, and relates to the technical field of intelligent control.The method comprises the following steps: acquiring target light modulation parameters by querying a preset control strategy mapping table according to a rear-end collision risk level; generating a digital driving signal based on the target light modulation parameters and delivering the digital driving signal to a tail lamp driving circuit to adjust the output light intensity or flicker frequency of a tail lamp lighting module to complete adaptive warning, wherein the target light modulation parameters comprise a pulse width modulation duty cycle or light pattern coding information.The application can realize adaptive modulation of a tail lamp.
