Alerter augmentation system
First Claim
Patent Images
1. A system comprising:
- one or more processors configured to determine an alertness of an operator of a vehicle system, the one or more processors also configured to generate operator input requests that are separated in time by a temporal delay, the one or more processors configured to change one or more of the temporal delay between the input requests or a type of the input requests that are generated based at least in part on the alertness of the operator that is determined,wherein the one or more processors are configured to automatically switch from automatic control of movement of the vehicle system to manual control of the movement of the vehicle system responsive to the alertness of the operator decreasing below a first designated threshold score, andwherein the one or more processors are configured to automatically switch from manual control of the movement of the vehicle system to reduced operation automatic control of the movement of the vehicle system responsive to the alertness of the operator decreasing below a smaller, second designated threshold score.

Abstract
An alerter augmentation system includes one or more processors that determine an alertness of an operator of a vehicle system. The one or more processors also generate operator input requests that are separated in time by a temporal delay. These input requests seek responses or action by the operator in an attempt to keep or make the operator alert. The one or more processors change one or more of the temporal delay between the input requests and/or a type of the input requests that are generated based at least in part on the alertness of the operator that is determined.

12. A method comprising:
-
determining an alertness of an operator of a vehicle system using a monitoring system; changing one or more of a temporal delay between successive input requests provided by an alerter system of the vehicle system or a type of the input requests provided by the alerter system based at least in part on the alertness of the operator that is determined; automatically switching the vehicle system from automatic movement control to manual movement control responsive to the alertness of the operator decreasing below a first designated threshold score, and automatically switching from the manual movement control of the vehicle system to reduced operation of the automatic movement control of the vehicle system responsive to the alertness of the operator decreasing below a smaller, second designated threshold score. - View Dependent Claims (13, 14, 15, 16, 17)

18. A system comprising:
-
one or more processors configured to automatically instruct an alerter system to generate requests for operator input at time intervals in order to maintain an alertness of an operator controlling a powered system, the one or more processors also configured to direct the alerter system to one or more of change the time intervals between the requests or change a type of the requests responsive to a change in the alertness of the operator, wherein the one or more processors are configured to automatically switch from automatic control of movement of the powered system to manual control of the movement of the powered system responsive to the alertness of the operator decreasing below a first designated threshold score, and wherein the one or more processors are configured to automatically switch from manual control of the movement of the powered system to reduced operation automatic control of the movement of the powered system responsive to the alertness of the operator decreasing below a smaller, second designated threshold score. - View Dependent Claims (19, 20)
