Abstract
A control device is provided for operating a road-coupled hybrid vehicle, which is equipped with an electronic control unit, a first drive unit paired with a primary axle, and a second drive unit paired with a secondary axle. The control unit is designed to receive input variables including a specified sum target creep torque and a command to switch over from the single-axle operation to the two-axle operation with a specified all-wheel factor. The control unit sets a specified target torque for an internal combustion engine of the primary axle according to the all-wheel factor and detects the resulting actual coupling torque of the automatic transmission. If the functional module of the control unit ascertains a difference between the actual coupling torque and the sum target creep torque, the functional module specifies a corresponding target torque for an electric drive motor of the secondary axle to compensate for the difference.
