Abstract

Provided are a method and an apparatus for prediction of time available for autonomous driving, in a vehicle having autonomous driving capabilities and including at least one remote sensor configured to acquire vehicle surrounding information and at least one vehicle dynamics sensor configured to determine vehicle dynamics parameters. The method and apparatus include at least one of a positioning arrangement that provides map data with associated information, a route planning arrangement that enables route planning, and a real time information acquiring arrangement that acquires at least one of real time traffic information and real time weather information. The time available is calculated based on a planned route and at least one of vehicle surrounding information, vehicle dynamics parameters, map data with associated information, real time traffic information and real time weather information, for the planned route. The calculated time is output to a human machine interface in a vehicle.
