A method for operating a motor vehicle having an engine and an electric machine, a transmission, a battery, and an exhaust treatment system having a particulate filter. The battery discharges during a charge-depleting mode of the electrical machine and charges when the electrical machine operates as a generator such that the battery charge state moves between lower and upper limits. If a filter regeneration requirement is detected, the filter is regenerated by raising the temperature of the exhaust gas. When the need for filter regeneration is detected, the battery is discharged to below the lower limit, in the charge-depleting mode of the electrical machine, prior to the regeneration. Subsequently, to regenerate the filter, the engine is operated to raise the exhaust gas temperature by increasing the torque provided by the engine, and the electric machine operates as a generator to charge the battery and/or operate an auxiliary electrical load.
