System and Method for requesting input and suggesting takeover

Autonomous cars receive input from on-board sensors (e.g., radar, ultrasound, Lidar, cameras, navigation/mapping systems, accelerometer, etc.). The problem is that in some cases, there might not be enough information for an autonomous vehicle to successfully drive. In addition, these sensors are less reliable in the event of smoke, fog, dust, and unclear weather. Sensor failure is also possible after an accident or power surge.

Disclosed is a method for an autonomous vehicle to request and/or receive alternate input data if sensor data deemed unreliable or unavailable.

Implementation (pull):


1. The autonomous vehicle is driving

2. The vehicle determines some level of uncertainty, and requires additional information to complete a journey


3. The vehicle queries for alternate content from:


A. The driver: asks the driver what the speed limit is if it is not detectable

B. Alternate cameras: there could be a blind spot on a road that provides data to the vehicle

C. Peer vehicles: cars that have traversed the area can share recent data with new oncoming cars


4. Alternate content is used by the vehicle's navigation/drive system


5. Vehicle continues to drive without suspending the autonomous mode

Implementation (push):


1. The autonomous vehicle is driving


2. The vehicle detects a broadcast of alternate content


A. Construction zone sign with Quick Response (QR) code


B. Near Field signal


C. Geographically marked portion of the road


3. The content is received and prioritized

4. If there are multiple sources, the system determines which content is most reliable based on:


A. Content source


B. Content signature


C. Data fidelity


D. How recently the co...
