Abstract

Arrangements relating to the transfer of data from an autonomous vehicle to a remote operation computing system while the autonomous vehicle is operating in a remote operational mode are described. A driving environment of the autonomous vehicle can be sensed using a sensor system to acquire driving environment data. The sensor system includes a plurality of different types of sensors. A driving environment complexity can be determined. The availability of a communication channel between the autonomous vehicle and the remote operation computing system can be determined. A subset of the plurality of different types of sensors can be selected based on the determined driving environment complexity and/or the determined communication channel availability and/or its quality. Driving environment data acquired by the selected subset of the plurality of different types of sensors can be sent to the remote operation computing system.
