Abstract

A method of operating a hybrid powertrain comprising a motor-generator electric unit (500, fig 1) and an internal combustion engine 110 equipped with an SCR device 287 in an exhaust line 275. The method comprising the steps of: determining an overall power to be delivered by the hybrid powertrain (105, fig 1), monitoring a parameter TSCRinj indicative of a temperature in the exhaust line 275 upstream of the SCR device 287, and splitting the overall power Ptot into a first contributing value Pice of power to be delivered by the internal combustion engine 110 and a second contributing value Pmgu of power to be delivered by the motor-generator electric unit (500, fig 1), wherein the splitting of the overall power comprises the step of increasing the first contributing power value Pice, if the monitored temperature parameter TSCRinj is lower than a predefined threshold.
