Abstract

An operating method for a motor vehicle having a hybrid drivetrain includes, during a demand check, comparing at least one value which characterizes a current state of an exhaust-gas after-treatment device, with a setpoint value of the exhaust-gas after-treatment device. In response to the comparison indicating a deviation of the value characterizing the current state of the exhaust-gas after-treatment device from the setpoint value, a demand for a measure is indicated. The measure includes supplying charge gas, which includes recirculated exhaust gas, to the internal combustion engine during overrun operation. In addition, a capability check is carried out to detect conditions suitable for implementing the operating method.
