Abstract
A method for rating road classifications in navigational systems using fixed average speeds input into the system, to be replaced by or, if necessary, supplemented with continuously corrected, i.e., updated speed values.
Claims15
A method for rating road classifications in a vehicle navigational system, comprising:
- assigning an average vehicle-speed value to at least one partial section of a particular driven road, for rating purposes;
- and
- performing a recalculation and an updating of the average vehicle speed value relevant to the rating, during travel, at repeated instants in accordance with actually reached speeds.
A method for rating road classifications in a vehicle navigational system, comprising:
- assigning an average vehicle-speed value to at least one partial section of a particular driven road, for rating purposes;
- adapting the average vehicle-speed value relevant to the rating, during travel, at repeated instants in accordance with actually reached speeds, through a recalculation;
- and
- filtering, for the recalculation, over time for the average vehicle-speed value relevant to the rating.
A method for rating road classifications in a vehicle navigational system, comprising:
- assigning an average vehicle-speed value to at least one partial section of a particular driven road, for rating purposes;
- adapting the average vehicle-speed value relevant to the rating, during travel, at repeated instants in accordance with actually reached speeds, through a recalculation;
- and
- variable weighting an influence of an adaptation on the recalculation.
A method for rating road classifications in a vehicle navigational system, comprising:
- assigning an average vehicle-speed value to at least one partial section of a particular driven road, for rating purposes;
- adapting the average vehicle-speed value relevant to the rating, during travel, at repeated instants in accordance with actually reached speeds, through a recalculation;
- and
- displaying an arrival time at a destination using a short-term adaptation, including a low time constant;
- wherein the recalculation of the average vehicle-speed value takes place using a long-term adaptation, including a larger time constant.
A method for rating road classifications in a vehicle navigational system, comprising:
- assigning an average vehicle-speed value to at least one partial section of a particular driven road, for rating purposes;
- adapting the average vehicle-speed value relevant to the rating, during travel, at repeated instants in accordance with actually reached speeds, through a recalculation;
- and
- proposing, by a system user, a starting value for the recalculation of the average value relevant to the rating.
A method for rating road classifications in a vehicle navigational system, comprising:
- assigning an average vehicle-speed value to at least one partial section of a particular driven road, for rating purposes;
- adapting the average vehicle-speed value relevant to the rating, during travel, at repeated instants in accordance with actually reached speeds, through a recalculation;
- and
- using an active average value as a base quantity and taking into account different road classifications using percentage changes, for the recalculation of the average vehicle-speed value.
A method for rating a road classification in a navigational system in a motor vehicle, comprising:
- assigning an average vehicle-speed value of the motor vehicle to at least one partial section of a particular road being driven on by the motor vehicle;
- adapting an average value of a vehicle speed relevant to a rating during travel by recalculating at repeated instants according to an actually reached speed;
- and
- rating the average vehicle-speed for the road classification of the particular road being driven on by the motor vehicle.
