Method for traffic-flow-conditioned adaptation of stopping processes to a synthetically modulated speed profile along a route travelled along by a vehicle and control device for carrying out the method

摘要

A method performs traffic-flow-conditioned adaptation of stopping processes to a synthetically modulated speed profile along a route traveled along by a vehicle. A route is selected on the basis of map data stored in a data record. The route is divided into route segments and a synthetically modulated speed profile is generated for each route segment. While the driver is travelling along at least part of the selected route, the method senses how often and for how long the vehicle stops in the route segments. The synthetically modulated speed profile is adapted for at least one route segment according to the detected stopping processes.

1. A method for traffic-flow-conditioned adaptation of stopping processes to suit a synthetically modulated speed profile along a path taken by a vehicle, comprising:
selecting a path based on map data stored in a data record; splitting the path into path segments and producing a synthetically modulated speed profile for each path segment; travelling along at least one portion of the path by a driver in the vehicle; producing recorded stopping processes by recording how many times and for how long the vehicle stops in the path segments taken when travelling along the at least one portion of the path; and adapting the synthetically modulated speed profile for at least one path segment to suit the recorded stopping processes, wherein the synthetically modulated speed profile is produced by assigning a maneuver class to each path segment, each maneuver class being selected from a matrix of maneuver classes that contains a plurality of constant speed maneuver classes, a plurality of acceleration maneuver classes and a plurality of deceleration maneuver classes, each maneuver class in the matrix of maneuver classes has an associated input speed and an associated output speed of the vehicle, each maneuver class in the matrix of maneuver classes has an average speed or has average acceleration/deceleration of the vehicle, and each maneuver class in the matrix of maneuver classes has a tolerance band for the average speed or average acceleration/deceleration based on a tally of how many times the maneuver class has occurred so far while travelling on the path.
