20130096792 | METHOD FOR CONTROLLING THE DRIVING MODE OF A MOTOR VEHICLE - A method of controlling the driving mode of a motor vehicle, having a largely automated drive-train including a drive motor, a transmission and a separator clutch arranged between the motor and transmission, such that while driving, if certain operating conditions exist and a speed profile 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 the occurrence of a termination signal.
