Object position history playback for automated vehicle transition from autonomous-mode to manual-mode

1. A system for operating an automated vehicle, said system comprising:

a perception-sensor used to determine a rendering of an area proximate to a host-vehicle;

a display operable to convey to an operator of the host-vehicle a position of an object present in the area in accordance with the rendering; and

a controller-circuit in communication with the perception-sensor and the display, said controller-circuit configured to operate the host-vehicle in an autonomous-mode, and operate the display to convey to the operator a history of the position of the object in accordance with the rendering, said history conveyed in response to initiating a transition of operation of the host-vehicle from the autonomous-mode to a manual-mode.

2. The system in accordance with claim 1 , wherein events depicted in the history are characterized as having occurred in real-time, and the history is characterized by a playback-speed, said playback-speed faster than real-time.

3. The system in accordance with claim 1 , wherein the controller-circuit is configured to determine a threat-level of the object, and highlight the object in the history, said highlight of the object characterized by an intensity, said intensity determined in accordance with the threat-level of the object.

4. The system in accordance with claim 3 , wherein the controller-circuit is configured to operate the display to convey positions of a plurality of objects, said plurality of objects characterized by a number-of-objects, wherein the number-of-objects highlighted is determined in accordance with a time-interval from initiating the transition and to when the manual-mode is required.

5. A controller-circuit for operating an automated vehicle, said system comprising:

an input configured to communicate with a perception-sensor used to determine a rendering of an area proximate to a host-vehicle;

an output configured to communicate with a display operable to convey to an operator of the host-vehicle a position of an object present in the area in accordance with the rendering; and

a processor in communication with the perception-sensor and the display, said processor configured to operate the host-vehicle in an autonomous-mode, and operate the display to convey to the operator a history of the position of the object in accordance with the rendering, said history conveyed in response to initiating a transition of operation of the host-vehicle from the autonomous-mode to a manual-mode.

6. The controller-circuit in accordance with claim 5 , wherein events depicted in the history are characterized as having occurred in real-time, and the history is characterized by a playback-speed, said playback-speed faster than real-time.

7. The controller-circuit in accordance with claim 5 , wherein the processor is configured to determine a threat-level of the object, and highlight the object in the history, said highlight of the object characterized by an intensity, said intensity determined in accordance with the threat-level of the object.

8. The controller-circuit in accordance with claim 7 , wherein the processor is configured to operate the display to convey positions of a plurality of objects, said plurality of objects characterized by a number-of-objects, wherein the number-of-objects highlighted is determined in accordance with a time-interval from initiating the transition and to when the manual-mode is required.

9. A method for operating an automated vehicle, said method comprising:

receiving from a perception-sensor a rendering of an area proximate to a host-vehicle;

operating the host-vehicle in an autonomous-mode;

determining a history of a position of an object present in the area;

initiating a transition of operation of the host-vehicle from the autonomous-mode to a manual-mode; and

in response to initiating the transition, conveying to an operator of the host-vehicle the history of the position of the object in accordance with the rendering.

10. The method in accordance with claim 9 , wherein events depicted in the history are characterized as having occurred in real-time, and the history is characterized by a playback-speed, said playback-speed faster than real-time.

11. The method in accordance with claim 9 , wherein the method includes determining a threat-level of the object; and

highlighting the object in the history, said highlighting of the object characterized by an intensity, said intensity determined in accordance with the threat-level of the object.

12. The method in accordance with claim 11 , wherein the method includes

determining positions of a plurality of objects, said plurality of objects characterized by a number-of-objects, wherein the number-of-objects highlighted is determined in accordance with a time-interval from initiating the transition and to when the manual-mode is required.
