Manual vehicle control notification
First Claim
1. A method for notifying a driver to assume manual vehicle control, comprising:
- evaluating sensor data, acquired from one or more on-board sensors of a vehicle that is in an autonomous driving mode, to determine a driving condition of a road segment that is to be traveled by the vehicle;
determining a cognitive load of the driver based upon a type of activity associated with a first location from which the vehicle is traveling;
responsive to determining that the driving condition exceeds a complexity threshold, derived from the cognitive load, for autonomous driving decision making functionality, generating a driver alert to assume manual vehicle control;
determining a point in time at which to provide the driver alert relative to a point in time at which the road segment is encountered based upon the cognitive load, wherein;
when the cognitive load of the driver has a first cognitive load value, selecting the point in time at which to provide the driver alert to be a first time interval away from the point in time at which the road segment is encountered,when the cognitive load of the driver has a second cognitive load value different than the first cognitive load value, selecting the point in time at which to provide the driver alert to be a second time interval, different than the first time interval, away from the point in time at which the road segment is encountered; and
providing the driver alert to the driver of the vehicle at the point in time, relative to the point in time at which the road segment is encountered.

Abstract
One or more techniques and/or systems are provided for notifying drivers to assume manual vehicle control of vehicles. For example, sensor data is acquired from on-board vehicles sensors (e.g., radar, sonar, and/or camera imagery of a crosswalk) of a vehicle that is in an autonomous driving mode. In an example, the sensor data is augmented with driving condition data aggregated from vehicle sensor data of other vehicles (e.g., a cloud service collects and aggregates vehicle sensor data from vehicles within the crosswalk to identify and provide the driving condition data to the vehicle). The sensor data (e.g., augmented sensor data) is evaluated to identify a driving condition of a road segment, such as the crosswalk (e.g., pedestrians protesting within the crosswalk). Responsive to the driving condition exceeding a complexity threshold for autonomous driving decision making functionality, a driver alert to assume manual vehicle control may be provided to a driver.
