Method and Device for Entering the Coasting Mode of a Motor Vehicle, Considering an Entry Tolerance Band

A controller programmed to control a coasting mode of a vehicle by executing a program that causes the controller to:

• based on a current driving distance of the vehicle, predict a distance and/or a speed profile of the vehicle in the coasting mode;
• compare the predicted distance and/or the predicted speed profile of the vehicle with a tolerance band limit of an entry tolerance band around a target distance and/or around a target speed of a distance and/or speed control of the vehicle to produce a comparison, wherein the entry tolerance band is narrower in relation to at least one tolerance band limit than an exit tolerance band, which is used to decide whether to exit from the coasting mode;
• and
• start the coasting mode depending on the comparison.

A method for controlling a coasting mode of a vehicle during a distance and/or speed control of the vehicle, the method comprising:

• predicting, based on a current driving distance of the vehicle, a distance and/or speed profile of the vehicle in the coasting mode;
• comparing the predicted distance and/or the predicted speed profile of the vehicle with a tolerance band limit of an entry tolerance band around a target distance and/or around a target speed of the distance and/or speed control of the vehicle to produce a comparison, wherein the entry tolerance band is narrower in relation to at least one tolerance band limit than an exit tolerance band that is used to decide whether to exit from the coasting mode;
• and
• starting the coasting mode depending on the comparison.
