  "textContent": "A method for estimating a friction coefficient of a roadway by a transportation vehicle, wherein a control device of the transportation vehicle receives a first estimated value of a maximum horizontal force from a traction control system that is transmitted to the roadway by a wheel of the transportation vehicle. A control device receives a second estimated value of a wheel contact-patch force of the wheel from a damper controller and calculates the friction coefficient as a vehicle-independent friction coefficient based on the estimated values from the wheel contact-patch force and the horizontal force.",
