The invention discloses a method for operating an exhaust system of an internal combustion engine, the exhaust system and a motor vehicle. The invention relates to a method for operating an exhaust system 1 of an internal combustion engine 2, the exhaust system 1 comprising an LNT catalytic converter 3 arranged in a first control circuit RK1 and an energy storage unit 4 arranged in a second control circuit RK2, the energy storage unit 4 being designed to supply current to an electric heating unit 5. The nitrogen oxide storage state SSZ of the LNT catalytic converter 3 is adjusted in a first control circuit RK1, and the state of charge LZ of the energy storage unit 4 is adjusted in a second control circuit RK2. The first control circuit RK1 and the second control circuit RK2 are connected to each other. In addition, the exhaust system 1 and the motor vehicle having such an exhaust system 1 are disclosed. 本发明公开了运转内燃发动机的排气系统的方法、排气系统和机动车辆，涉及一种用于运转内燃发动机2的排气系统1的方法，该排气系统1包括布置在第一控制回路RK1中的LNT催化转化器3和布置在第二控制回路RK2中的能量存储单
