Abstract

A vehicle comprises an aftertreatment system configured to reduce constituents of an exhaust gas. The vehicle also includes a controller configured to determine a predicted load on the vehicle during a route, and adjust at least one of a temperature of the aftertreatment system or an amount of a reductant inserted into the aftertreatment system based on the predicted load.
