Abstract
A control device for operating a roadbound all-wheel vehicle having a first electric drive motor assigned to a primary axle and a second electric drive motor assigned to a secondary axle, including a control unit configured such that, when a defined dynamic driving mode of the driver is identified based on the driver request gradient during a operating mode with the first motor activated and the second motor deactivated for a predefined time window, an overall setpoint moment characteristic predefined by a new driver request is ascertained. This is set, in accordance with an axle distribution factor that is likewise predefined, by reducing the setpoint moment of the primary motor and by activating and increasing the setpoint moment of the secondary motor, even when the predefined overall setpoint moment characteristic lies below a maximum possible moment of the primary motor.
