US 12,644,979 B2 · Adaptive radar waveform repeater

Abstract

Systems and techniques of the present disclosure may allow traffic control indicators, such as road signs or signals along a roadway to send information to a radar device at an autonomous vehicle (AV). A traffic control indicator may receive a radio signal sent from the radar device at the AV. A radar apparatus at the traffic control indicator may add information that simulates movement of the traffic control indicator and message data to an updated radar signal. The updated radar signal may then be sent from the traffic control indicator radar apparatus to the AV radar device. The AV radar device may then extract the message data from the updated radar signal based on updated radar signal including the movement information. A controller that controls the AV may then control the AV to drive according to the message data extracted from the updated radar signal.

Dependent claims

An apparatus comprising:

a traffic control indicator configured to convey driving instructions that regulate traffic;
and
a radar module coupled to the traffic control indicator, wherein the radar module is configured to:
receive a radar signal;
process the radar signal to generate an updated radar signal, the updated radar signal comprising a false movement indicator configured to trigger a vehicle radar system to process the updated radar signal;
and
transmit the updated radar signal for receipt by the vehicle radar system, thereby enabling the vehicle radar system to process the updated radar signal and extract message data comprising the driving instructions that regulate traffic.
