Abstract
A method for supporting energy-efficient deceleration of a vehicle includes determining a reference deceleration depending on a current speed or a speed profile of the vehicle, determining a starting time point and a starting speed of a deceleration of the vehicle, and determining a real energy consumption and a real distance between the starting time point and a current time point and/or ending time point of the deceleration. The method also includes calculating a reference time and a reference distance for a deceleration with the determined reference deceleration between the determined starting speed and the current speed and/or the speed at the ending time point of the vehicle, calculating an energy consumption for a differential distance from the determined real distance and the calculated reference distance, and calculating a real total energy consumption as the sum of the determined real energy consumption of the deceleration and the calculated energy consumption for the differential distance. Further, the method includes calculating a reference energy consumption for the reference deceleration from the starting speed to the current and/or ending speed depending on a predefined deceleration type of the reference deceleration and/or depending on the determined real energy consumption of the deceleration, and then providing an energy-saving potential on the basis of a difference between the real total energy consumption and the calculated reference energy consumption.
