A method and a control device are provided for operating a road-coupled hybrid vehicle. The hybrid vehicle has an electronic control unit, a primary motor associated with a first axle, and a secondary motor associated with a second axle. By way of the electronic control unit, the primary motor and the secondary motor are basically controlled in a drive-oriented manner such that preferentially only a single-axle drive by the primary motor is provided. Beginning with the secondary motor switched off, when a traction requirement is determined, the secondary motor is switched on, regardless of whether the vehicle is traveling on a curve. Beginning with the secondary motor switched on, when a traction requirement is not present, the secondary motor is not switched off until it is determined that the vehicle is not, or is no longer, traveling on a curve. A traction requirement is preferably determined at least when an expected traction requirement in the longitudinal direction is predicted when wheel slip is recognized or when the ASC control is active. An expected traction requirement in the longitudinal direction is predicted when a requested longitudinal dynamic setpoint parameter exceeds a defined threshold value based on a longitudinal dynamic potential parameter.
