Teleassistance data prioritization for self-driving vehicles
A self-driving vehicle can operate by analyzing a live sensor view to autonomously operate acceleration, braking, and steering systems of the SDV along a current route. Based on a detected anomaly associated with the live sensor view, the SDV can transmit a teleassistance inquiry to a backend transport system in accordance with a data prioritization scheme. The SDV can receive a resolution response from the backend transport system based on the teleassistance inquiry, and proceed in accordance with the resolution response.
