Motor vehicle operating method, involves changing operating phases into free-wheel operation phase, and activating free-wheel operation phase based on expected time curve and longitudinal dynamics control mode

摘要

#CMT# #/CMT# The method involves detecting an environment of a vehicle, and determining driving conditions in which a fuel-saving control is provided. Prediction of regulating intervention is carried out during operation phases, and expected time curve (VE) of a state variable (V) is determined based on a travel distance of another vehicle lying ahead of the former vehicle. The operating phases are changed into a free-wheel operation phase i.e. idling operation phase. The free-wheel operation phase is activated based on the expected time curve and a longitudinal dynamics control mode. #CMT#USE : #/CMT# Method for operating a motor vehicle. #CMT#ADVANTAGE : #/CMT# The method enables changing the operating phases into the free-wheel operation phase i.e. idling operation phase, that is activated based on the expected time curve and the longitudinal dynamics control mode, thus operating the vehicle with reduced fuel consumption. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a graphical representation illustrating a time curve of expected velocity during an idle operation of a vehicle.'(Drawing includes non-English language text)' TB1-TB3 : Tolerance bands TD1, TD2 : Minimum residence times V : State variable VE : Expected time curve VSetz : Setting velocity.
