Method and control device for operating a roadbound all-wheel vehicle

A non-transitory computer readable medium having stored thereon a computer program that, when executed by a control device for a roadbound all-wheel drive vehicle having a first electric drive motor assigned to a primary axle and a second electric drive motor assigned to secondary axle, cause the control device to:

• when a defined dynamic driving mode of the driver is identified on a basis of a driver-input gradient during an operating mode with the first electric drive motor activated and the second electric drive motor deactivated for a predefined time window, ascertain a total target torque curve predefined by a new driver input, wherein the total target torque curve is set in accordance with an axle distribution factor that is likewise predefined, by reducing a target torque of the first electric drive motor and by activating and increasing a target torque of the second electric drive motor,
• wherein the switching-on of the magnetic field of the second electric drive motor, and thereby the delay time, are started upon detection of at least one of an increased load on the first electric drive motor or a changeover from coasting to traction on a basis of the driver input.

A control device for operating a roadbound all-wheel drive vehicle having a first electric drive motor assigned to a primary axle and a second electric drive motor assigned to secondary axle, the control device comprising:

• at least one electronic control unit configured to:
• when a defined dynamic driving mode of the driver is identified on a basis of a driver-input gradient during an operating mode with the first electric drive motor activated and the second electric drive motor deactivated for a predefined time window, ascertain a total target torque curve predefined by a new driver input, wherein the total target torque curve is set in accordance with an axle distribution factor that is likewise predefined, by reducing a target torque of the first electric drive motor and by activating and increasing a target torque of the second electric drive motor,
• wherein a defined dynamic driving mode of the driver is identified on a basis of the driver-input gradient when the current driver-input gradient exceeds a predefined threshold value.
