Abstract

A method adapts an energy supply of a vehicle drive system, where values of at least a first energy utilization characteristic variable which represents a first energy utilization process in the vehicle are determined, and values of at least one parameter which represents at least one peripheral condition of the energy utilization during the first energy utilization process are determined. A mathematical relationship is determined between these values, after which a profile data record is made which contains a data record and/or learning data on the basis of the mathematical relationship. As a function of the profile data record, at least one adaptation information item for adapting the energy supply of the drive system of the vehicle for a second energy utilization process is determined, and/or an adaptation information item for adapting the energy supply of the drive system of a second vehicle for an energy utilization process is determined.
