US 2026/0121773 A1 · AUTONOMOUS VEHICLES OPERATING WITH LOW LOCATION SIGNAL STRENGTH

Abstract

Various systems and methods are presented regarding utilizing technology onboard a vehicle to mitigate the effects of communication signals being deleteriously affected/lost when operational surroundings cause occlusion/loss of receipt of positioning/location signals at the vehicle. The vehicle can be operating non-autonomously, partially autonomously, or autonomously. To supplement the lost/occluded signals position information of other systems proximate to the vehicle can be obtained/utilized. The other systems can include another vehicle, a mobile device, an internet, and suchlike. Also, onboard devices can be utilized to determine the location, such as an onboard camera system providing information regarding street signs, building facades, and suchlike.

Dependent claims

A system, located on a first vehicle operating in at least a partially autonomous manner, comprising:

a memory that stores computer executable components;
and
a processor that executes the computer executable components stored in the memory, wherein the computer executable components comprise:
a signal component configured to determine a signal quality of first navigation signals received at the first vehicle, wherein the first navigation signals are received from a first external system;
and
a navigation component configured to, in response to determining, by the signal component, the first navigation signals have a signal quality below a signal strength threshold, operate the first vehicle utilizing a second navigation signal received from a second external system.

3 more elements

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

monitor signal strength of first signals received at a first vehicle operating in an autonomous manner, wherein the first signals are received from a first external system and are utilized for navigation of the vehicle;
determine a drop in the signal strength of the first signals from a first signal strength to a second signal strength, wherein the first signal strength is acceptable for the autonomous operation of the first vehicle based on the first signals and the second signal strength is below a threshold acceptable for the autonomous operation of the first vehicle based on the first signals;
and
switch navigation of the first vehicle based on a second signal, wherein the second signal is sourced from a second external system, wherein the first external system is a global positioning system and the second external system is located on a second vehicle communicatively coupled to the first vehicle.
