Method, apparatus and mobile user appliance for adapting an energy utilization process of a vehicle. At least one value of an energy utilization characteristic quantity is ascertained that represents a first energy utilization process in a first vehicle, and a value of a parameter is ascertained that represents at least one constraint of the energy utilization in the first vehicle during the energy utilization process. A mathematical relationship between at least one of the provided values of an energy utilization characteristic quantity, the values of the parameters of the first vehicle and parameters for a possible second energy utilization process of a second vehicle is ascertained. Further, a data record is provided on the basis of the ascertained mathematical relationship, and a profile data record is provided that comprises the data record.
