Claim:
1. A method for regulating a temperature in an exhaust stream in a motor vehicle through control of a driveline of the vehicle; the motor vehicle comprises: a driveline comprising a combustion engine connected to a gearbox, wherein the gearbox has several discrete gears, and an exhaust system arranged for the removal of an exhaust stream from the combustion engine; wherein the method comprises the steps: obtaining one or several first parameters P controlling the gearbox, and thus controlling an operating point in the combustion engine through a downshift to a lower gear for increasing an engine speed and reducing a load on the combustion engine, if a value of the first temperature difference exceeds a first threshold value; and an upshift to a higher gear for reducing the engine speed and increasing the load on the combustion engine, if a value of the first temperature difference is below a second threshold value.
