Abstract
A method for regulation of a concentration/fraction of one or several substances comprised in an exhaust system in a motor vehicle through control of its driveline: The driveline includes a combustion engine which may be connected to a gearbox via a clutch device, wherein the gearbox has several discrete gears, and an exhaust system for removal of an exhaust stream from the combustion engine; the method includes obtaining one or several first parameters P1 related to at least one first concentration/fraction C1/X1 of one or several substances comprised in the exhaust system; and controlling the gearbox, and thus an operating point in the combustion engine, based on the parameters P1 for regulation of a concentration/fraction CEx/XEx of one or several substances in the said exhaust system. Further, a computer program, a computer program product, a system and a motor vehicle comprising such a system are disclosed.
