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 the 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, characterized in that the controller is configured to operate the vehicle in accordance with control-parameters that control one or more of a following-distance and a travel-speed of the vehicle when the control-mode of the vehicle is automated-control and the readiness-state of the operator is ready, and the controller is configured to modify the control-parameters for the automated-control of the vehicle when the readiness-state of the operator is not-ready, said modification of the control-parameters allowing for an increase of the take-over-interval and wherein the increase of the take-over-interval is realized by one or more of an increased following-distance of the vehicle and a decreased travel-speed of the vehicle. 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 the 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, characterized in that the controller is configured to operate the vehicle in accordance with control-parameters that control one or more of a following-distance and a travel-speed of the vehicle when the control-mode of the vehicle is automated-control and the readiness-state of the operator is ready, and the controller is configured to modify the control-parameters for the automated-control of the vehicle when the readiness-state of the operator is not-ready, said modification of the control-parameters allowing for an increase of the take-over-interval and wherein the increase of the take-over-interval is realized by one or more of an increased following-distance of the vehicle and a decreased travel-speed of the vehicle. 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 the 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, characterized in that the controller is configured to operate the vehicle in accordance with control-parameters that control one or more of a following-distance and a travel-speed of the vehicle when the control-mode of the vehicle is automated-control and the readiness-state of the operator is ready, and the controller is configured to modify the control-parameters for the automated-control of the vehicle when the readiness-state of the operator is not-ready, said modification of the control-parameters allowing for an increase of the take-over-interval and wherein the increase of the take-over-interval is realized by one or more of an increased following-distance of the vehicle and a decreased travel-speed of the vehicle.
