Abstract:
1. A method for controlling an exhaust aftertreatment device of a vehicle hybrid drive, comprising: operating the hybrid drive to drive a vehicle via power produced in one mode selected from a group of three modes including a mode of driving the vehicle only by a combustion engine, a mode of driving the vehicle only by a non-combustion motor, or a mode of driving the vehicle by the combustion engine and the non-combustion motor, the one mode being a function of a temperature of the exhaust aftertreatment device, wherein the hybrid drive is operated to drive the vehicle via power produced only by the combustion engine if the temperature of the exhaust aftertreatment device is higher than a threshold value and an exhaust temperature of the combustion engine is lower than the temperature of the exhaustafter treatment device, and wherein the hybrid drive is operated to drive the vehicle via power produced in a mixed operating mode if the temperature of the exhaust aftertreatment device is higher than the threshold value and the exhaust gas temperature of the combustion engine is higher than the temperature of the exhaust aftertreatment device; and conducting exhaust gas of the hybrid drive at least partially through the exhaust aftertreatment device, the engine and motor each capable of providing output to power the vehicle.
