Method for operating a motor vehicle, wherein the motor vehicle has a hybrid drive device which has an electric motor, an internal combustion engine and a particle filter assigned to the internal combustion engine, wherein the internal combustion engine is operated at times to regenerate the particle filter, characterised in that - the regeneration is initiated when the internal combustion engine is operated such that it provides a drive torque which is greater than a preset torque required for driving the motor vehicle, wherein an energy store is charged in that the electric motor is driven by means of the internal combustion engine, wherein a differential torque of drive torque and preset torque is applied to the electric motor, that - the regeneration is initiated in a first operational mode only when it is determined by means of a navigational device that an electric driving area lies ahead for in which an operation of the internal combustion engine and/or the regeneration of the particle filter is not desired, wherein the charging state of the energy store to be achieved when charging the energy store is determined on the basis of the length of a portion, situated in the electric driving area, of an expected driving route, determined by means of the navigational device, of the motor vehicle, and that - the regeneration In the first operational mode for is initiated only when a fill level of the particle filter is greater than a threshold value, wherein during operation of the electric motor has a generator a first threshold value corresponding to an empty particle filter is used as a threshold value and in the event of a driving operation of the motor vehicle alternatingly only with the electric motor and only with the internal combustion engine, a second threshold value selected to be greater than the first threshold value is used as a threshold value. - the regeneration is initiated when the internal combustion engine is operated such that it provides a drive torque which is greater than a preset torque required for driving the motor vehicle, wherein an energy store is charged in that the electric motor is driven by means of the internal combustion engine, wherein a differential torque of drive torque and preset torque is applied to the electric motor, that - the regeneration is initiated in a first operational mode only when it is determined by means of a navigational device that an electric driving area lies ahead for in which an operation of the internal combustion engine and/or the regeneration of the particle filter is not desired, wherein the charging state of the energy store to be achieved when charging the energy store is determined on the basis of the length of a portion, situated in the electric driving area, of an expected driving route, determined by means of the navigational device, of the motor vehicle, and that - the regeneration In the first operational mode for is initiated only when a fill level of the particle filter is greater than a threshold value, wherein during operation of the electric motor has a generator a first threshold value corresponding to an empty particle filter is used as a threshold value and in the event of a driving operation of the motor vehicle alternatingly only with the electric motor and only with the internal combustion engine, a second threshold value selected to be greater than the first threshold value is used as a threshold value.
