APPARATUS AND METHOD FOR ESTIMATING AND USING A PREDICTED VEHICLE SPEED IN AN INDIRECT VISION DRIVING TASK

摘要

A method and apparatus for predicting vehicle speed during an indirect vision driving task. A further method and apparatus for optimizing the display of a camera return during an indirect vision driving task based on operator perceived vehicle speed as set by the display characteristics and the field-of-view of the camera. A further method and apparatus for using the perceived speed as a driving task aid, in particular, as an electronic aider for optimizing the driving scene display characteristics of scene compression and camera field-of view. In this manner, the invention adjusts the perceived speed in order to match the operator's cognitive flow to the control dynamics needed from the operator for the task. The invention has application to autonomous driving where manual intervention is incorporated during critical events for particular tasks; and with limited display space within the vehicle, the display format is adjusted by the invention according to the operator's task needs.

主权项

1. A method for aiding an operator during performance of indirect vision driving task in a vehicle, while viewing a display of at least one video camera return of a driving scene via a display device, comprising:
determining parameters for a display being viewed during an indirect vision driving task and of a camera providing a camera return that is being displayed; determining an actual speed of the vehicle during the indirect vision driving task; calculating an estimated operator-perceived driving performance for the operator of the vehicle as would be expected to be visually perceived and mentally interpreted by the operator as being the operator's actual driving performance during performance of an indirect vision driving task while viewing scene display on the display device based on one or more of the display parameters, camera parameters, driving course, and the actual vehicle speed; and adaptively controlling, via a processor, display characteristics of scene compression and/or field-of view for the display of the driving scene on the display device to the operator in a manner so as to mitigate differences between the estimated operator-perceived driving performance and the operator's actual driving performance during the performance of the indirect vision driving task.
