Abstract
Official abstract text for this publication.
A system for changing a control-mode of an automated vehicle from automated-control to manual-control includes an operator-detection device and a controller. The operator-detection device is operable to detect a readiness-state of an operator of a vehicle while a control-mode of the vehicle is automated-control. The controller is configured to forecast a future-time when the control-mode of the vehicle should change from automated-control to manual-control and determine a take-over-interval for an operator to assume manual-control of the vehicle once notified. The take-over-interval is determined based on the readiness-state. The controller is also configured to notify the operator that the control-mode of the vehicle should change from automated-control to manual-control no later than the take-over-interval prior to the future-time.
First claim
Opening claim text (preview).
We claim: 1. A system for changing a control-mode of an automated vehicle from automated-control to manual-control, said system comprising: an operator-detection device operable to detect a readiness-state of an operator of a vehicle while a control-mode of the vehicle is automated-control; a controller configured to forecast a future-time when the control-mode of the vehicle should change from automated-control to manual-control, determine a take-over-interval for an operator to assume manual-control of the vehicle once notified, wherein the take-over-interval is determined based on the readiness-state, and notify the operator that the control-mode of the vehicle should change from automated-control to manual-control no later than the take-over-interval prior to the future-time, wherein the controller is configured to operate the vehicle in accordance with control-parameters when the control-mode of the vehicle is automated-control and the readiness-state of the operator is ready, and the control-parameters are modified when the readiness-state of the operator is not-ready to allow for an increase of the take-over-interval. 2. The system in accordance with claim 1 , wherein the readiness-state is determined based on body-orientation of the operator. 3. The system in accordance with claim 2 , wherein the body-orientation is determined based on a foot-position of a foot of the operator. 4. The system in accordance with claim 2 , wherein the body-orientation is determined based on a facing-direction of the operator. 5. The system in accordance with claim 2 , wherein the body-orientation is determined based on a head-pose of the operator. 6. The system in accordance with claim 1 , wherein the readiness-state is determined based on a distraction-level of the operator. 7. The system in accordance with claim 6 , wherein the distraction-level is increased when the operator attends to a child present in the vehicle. 8. The system in accordance with claim 1 , wherein the increase of the take-over-interval is realized by one of increased following-distance and decreased travel-speed.
