Abstract

A vehicular alert system includes an autonomous aerial vehicle and a central computer. The autonomous aerial vehicle includes a processor, a display, and a detector. The processor controls a data transceiver. The detector detects one or more vehicular condition. The central computer communicates with the autonomous aerial vehicle via the data transceiver. The central computer includes a memory device. The memory device stores vehicular condition data and road condition data. The central computer communicates one of a vehicular condition or a road condition to the autonomous aerial vehicle. The processor of the autonomous aerial vehicle displays the received condition on the display.

First claim

What is claimed is:

1. A non-transitory computer readable storage medium having stored codes executable by a computer to implement a vehicular alert method, comprising:
receiving at the computer, detected data including vehicular condition data and road condition data transmitted by at least one of a plurality of autonomous aerial vehicles; and
comparing the detected data with preset hazardous parameters stored in a look up table, and upon determining a match with a preset hazardous parameter, causing at least one of the plurality of autonomous aerial vehicles to display a hazard signal and a reduce speed signal on a display,
wherein the at least one autonomous aerial vehicle displays a reduced speed limit that is reduced with respect to a legal speed limit,
wherein the reduced speed limit displayed depends upon a type of the preset hazardous parameter matched, and
wherein each of the preset hazardous parameters stored in the look up table is assigned a driver notification priority score from 0-100.

2. The computer program product of claim 1 , wherein at least one of the plurality of autonomous aerial vehicles detects location information and determines from the location information the legal speed limit and displays both the legal speed limit and a detected vehicle speed on the display.

3. The computer program product of claim 2 , wherein at least one of the plurality of autonomous aerial vehicles travels ahead of and positions the display to be viewable by a driver of a vehicle traveling at speed, and flashes the detected vehicle speed if the detected vehicle speed exceeds the speed limit.

4. The computer program product of claim 1 , wherein the preset hazardous parameters include one or more of traffic jam, black ice, slippery road, animal debris, and potholes.
