The invention relates to a thermal-management system for a vehicle comprising:



at least one calories storage and/or frigories storage (S1, S2),
at least one element of the vehicle to be heated or cooled,
at least one source of calories or frigories,
detection means adapted to detect whether calories or frigories are available at one of the said sources,
control means able to distribute the calories or frigories available at the sources to the elements to be heated or cooled, according to transient and nominal needs.
characterized in that it comprises prediction means capable of making at least one prediction aimed at determining:
whether calories or frigories will be available at a later date from any of the said sources and/or,
whether a need for calories or frigories will exist at a later date at one of the said elements to be heated or cooled.
