Patent ID: 8494737

Claim:
A method of controlling a driving mode of a motor vehicle, having a drive-train that is largely automated and comprises a drive motor, either an incrementally or a continuously adjustable transmission and at least one separator clutch arranged between the drive motor and the transmission, such that while driving, if certain operating conditions exist and a speed profile (v F (x FS )) calculated with reference to topographical data and vehicle parameters for a road section lying ahead is suitable, the drive-train is disengaged and driving continues in a coasting mode until an occurrence of a termination signal, the method comprising the steps of: determining a calculated speed profile (v F (x FS )) for a case of immediate disengagement of the drive-train continually at successive, equidistant travel points along a driving stretch (x FS ); evaluating the calculated speed profile (v F (x FS )) in each case in relation to a lower speed limit (v Gr — U ) and an upper speed limit (v Gr — O ); and only enabling coasting if, for a specified minimum number (n X — Min ) of successive travel points, a result of the evaluation is, in each case, positive.
