Abstract:
A method for regulation of a concentration/fraction of one or several substances in an exhaust stream in a motor vehicle through control of its driveline. The motor vehicle includes a driveline comprising a combustion engine; a driveline comprising a combustion engine connected to a gearbox, and an exhaust system for removal of an exhaust stream from the engine. The method includes the step: controlling the driveline for activation or deactivation of coasting of the vehicle based on one or several first parameters P1 for the regulation of a concentration/fraction CEXIXEX of one or several substances TEX in the exhaust stream, where at least one of the or several first parameters P1 are a first concentration/fraction difference between the first concentration/fraction C1/X1 in the exhaust stream and a reference concentration/fraction CRefIXRef. Further, a computer program, a computer program product, a system and a motor vehicle such a system are disclosed.
