Patent ID: 8615361

Claim:
A method for acquiring a data record which represents a predicted speed of a vehicle, so as to produce a corrected speed profile, the corrected speed profile including speed information over a multiplicity of route points or a multiplicity of elapsed route-driving times, comprising: making available a first data record by which route points are assigned to each of a multiplicity of routes; making available a second data record by: identifying a multiplicity of driving processes, each driving process having an entry speed and an exit speed; acquiring measured values for speed during data acquisition trips, the measured values for speed being acquired at respective route points; and using the measured values to assign driving behavior information to each driving process such that the second data record defines the multiplicity of driving processes for a driving style; selecting a selected route on the basis of the first data record; determining a preliminary speed profile for travel of the vehicle over the selected route; using the preliminary speed profile to divide up the selected route into route sections, each section being assigned one of the driving processes; and producing the corrected speed profile by assigning speed information to each driving process assigned to the selected route, the speed information being assigned using the second data record, wherein for at least one driving process assigned to the selected route or group of driving processes assigned to the selected route, speed information is assigned by taking into account a preceding or succeeding driving process or group of driving processes.
