Abstract: A method for operating a motor vehicle generates a change-operating-mode signal to change operation from a normal mode with an engine engaged and running to a coasting mode with the engine disengaged and/or switched off in response to a freewheeling distance exceeding a threshold. The freewheeling distance may be based on state parameters of the motor vehicle, such as position, speed, acceleration, weight, tire pressure, braking pressure, and air resistance, for example, data related to a second vehicle obtained from forward sensors, for example, and/or ambient parameters such as air temperature, wind speed, and wind direction, for example.
