Optimization method for the braking process of hybrid electric vehicles

This paper describes a algorithm which can caluclate the optimal braking velocity path to get a maximum of regenerative enery during braking. For a further reduction of fuel consumption and an increase of the potential of generation a method is presented which allows to generate the braking point and the braking path of a customized hybrid vehicle aiming at regenerating a maximum of energy during the braking process. This allows to use the generator in a most efficient way in order to waste only a minimum of braking energy. This procedure was integrated into an autonomously operating driver model to show the fuel saving of the optimal braking algorithm in comparison to normal braking.
