Abstract

A method for increasing the efficiency of the regeneration of a lean NOx trap (LNT) (281, fig.2) device of a hybrid powertrain 100 by interaction of the control strategies of the LNT and the hybrid power-train, comprising a motor-generator electric unit (MGU) 500, an internal combustion engine 110 with an exhaust system (270, fig.2), a lean NOx trap device, and an electronic control unit 450 to operate the method, the method comprising the following steps: comparing the exhaust gas temperature with a first predetermined threshold (TH2, fig.4) and with a second predetermined threshold (TH3, fig.4) and if the gas temperature is lower than said first threshold or higher than said second threshold actuating a hybrid optimisation strategy (HOS) manager. If the gas temperature is lower than the first threshold temperature the HOS manager will actuate the MGU as an electric generator and if the gas temperature is higher than the second threshold temperature the HOS manager will actuate the MGU as an electric motor.
