  • DEVICE AND METHOD FOR DETERMINING A ROADWAY COEFFICIENT OF FRICTION FOR A VEHICLE
    Publication number: 20110251759
    Abstract: A device for determining a roadway coefficient of friction for a vehicle, having a first tire steering device for setting a first predetermined steering angle (?1) of a first tire of the vehicle; a second tire steering device for setting a second predetermined steering angle (?2) of a second tire of the vehicle; a first sensor device for sensing a force necessary for setting the first predetermined steering angle (?1) of the first tire; a second sensor device for sensing a force necessary for setting the second predetermined steering angle (?2) of the second tire; and an evaluation device for determining the roadway coefficient of friction by evaluating the acquired data of the first and second sensor devices using a predetermined algorithm. Also, a method for determining a roadway coefficient of friction.
