Abstract
Systems and methods are provided for controlling an aftertreatment system of a vehicle. A system operating mode is determined for an aftertreatment device having an electrical heating element. A weighting coefficient is set based on the determined system operating mode. An optimized electrical heat input and an optimized engine heat input are determined based on the weighting coefficient. The aftertreatment device is then controlled to a target temperature based on the optimized electrical heat input and the optimized engine heat input.
