Example embodiments presented herein are directed towards a navigation unit, and corresponding method therein, for providing navigation instructions for an autonomous vehicle configured to be in an autonomous driving mode while in a certified autonomous road. The navigation unit is first configured to determine the autonomous vehicle is driving in an unplanned route or that the autonomous vehicle is deviating from a planned route. Thereafter, a trigger for routing the autonomous vehicle to a certified autonomous road is identified. The trigger is based on at least one of a current location, a time and date, a driving history or a calendar event. After the determination and identification previously described is performed, the vehicle is navigated to the certified autonomous road. Upon entering the road, and therefore being in an autonomous driving mode, a display screen will engage the driver so that the driver may input route planning information. Therefore, the navigation unit only interacts with the driver once the vehicle is in the autonomous driving mode. The example embodiments have the advantage of providing navigation without requiring an interaction with a driver operating a vehicle in a manual driving mode. |
