  • Method for heating an exhaust aftertreatment system and a hybrid vehicle adapted to heat an exhaust aftertreatment system
    Patent number: 11148657
    Abstract: Method for heating an exhaust aftertreatment system in a hybrid vehicle comprising an internal combustion engine and an electric machine, comprising the steps of measuring an exhaust condition for the function of the exhaust aftertreatment system, determining if the exhaust condition is below a predefined limit, applying a load from the electric machine on the internal combustion engine when the temperature is below the predefined limit, in order to increase the combustion engine torque, charging the battery system of the vehicle with power from the electric machine, and disconnecting the electric machine from the internal combustion engine when the exhaust condition for the function of the exhaust aftertreatment system is above the predefined limit. The advantage of the invention is that the heating of an exhaust aftertreatment system after a cold start of a hybrid vehicle can be improved, such that the exhaust emission of the vehicle can be minimized.
