1. A method, comprising:
determining, by a vehicle computer, a real-time level of fatigue of a driver of an autonomous vehicle;
determining, by the vehicle computer, an operating parameter associated with an environment in which the autonomous vehicle is traveling;
generating, by the vehicle computer and using a machine learning model, a predicted driving pattern of a second vehicle traveling in the environment;
determining, by the vehicle computer, a time interval for providing a hands-off steering wheel detection warning based at least in part on the real-time level of fatigue of the driver, the operating parameter, and the predicted driving pattern of the second vehicle;
identifying, by the vehicle computer, a final time interval for providing a hands-off steering wheel detection warning; and
outputting, by the vehicle computer, the hands-off steering wheel detection warning after the final time interval has elapsed.
