Zusammenfassung:	Systems and methods for conditioning an aftertreatment system. For example, a computer-implemented method for conditioning an aftertreatment system of a hybrid system including an electric motor and a combustion engine includes: determining whether the aftertreatment system is in a first temperature zone below a first temperature threshold; determining whether a power demand corresponding to the operation of the hybrid system is in a first power demand zone below a power threshold; and if the aftertreatment system is determined to be in the first temperature zone and the power demand of the hybrid system is determined to be in the first power demand zone, setting the hybrid system to compressor mode to heat the aftertreatment system.
