Abstract

The present invention relates to a method for classifying a predetermined group of energy consumers in a vehicle into critical and non-critical energy consumers, the energy consumers being powered by an energy storage or transformation, EST, system. The method comprises:- providing (S10) preview information of the vehicle operation, the preview information comprising at least one of a predicted road condition and a predicted road event;- processing (S20) the preview information with an estimation model adapted to relate a risk level associated with a power unavailability for each one of the energy consumers to the at least one predicted road condition and/or predicted road event;- classifying (S30) the energy consumers having a risk level higher than a predetermined risk level threshold value as critical energy consumers, and classifying the energy consumers with a risk level lower than the predetermined risk level threshold value as non-critical energy consumers;- estimating (S40) a required amount of energy and/or power for powering all the energy consumers in the predetermined group of energy consumers for the predicted road condition and/or the predicted road event;- estimating (S45) the available energy and/or power of the EST system ;- in response to determining that the required amount of energy and/or power for powering all the energy consumers in the predetermined group of energy consumers is higher than the available energy and/or power of the EST system for the predicted road condition and/or the predicted road event, powering (S51) the energy consumers classified as critical, and deactivating (S52) at least one of the energy consumers classified as non-critical.
