1. A system for sensor fusion for autonomous driving transition control, the system comprising:
- a processor operable to receive a plurality of steering sensor data from one or more sensors of a steering system and receive a plurality of driver state data from a plurality of driver state sensors, the processor configured to;
fuse the steering sensor data with the driver state data as a plurality of fused state data aligned in time;
determine whether to transition from an autonomous driving mode to a manual driving mode based on the fused state data;
command a steering motor actuator of the steering system autonomously in the autonomous driving mode;
command the steering motor actuator responsive to a driver input in the manual driving mode;
determine an attentive state of a driver based on time-averaging of the fused state data;
continue monitoring the fused state data after the transition from the autonomous driving mode to the manual driving mode has been initiated to determine an attentive state of a driver based on time-averaging of the fused state data; and
revert from the manual driving mode to the autonomous driving mode based on determining that the attentive state of the driver no longer meets one or more transition validity criteria.

Abstract
A system for sensor fusion for autonomous driving transition control includes a sensor fusion module and a decision making module. The sensor fusion module fuses a plurality of steering sensor data from one or more sensors of a steering system with a plurality of driver state data from a plurality of driver state sensors as a plurality of fused state data aligned in time. The decision making module determines whether to transition from an autonomous driving mode to a manual driving mode based on the fused state data.
