The present invention relates to a device (1) for determining a roadway coefficient of friction for a vehicle, having a first tire steering device (2) for setting a first predetermined steering angle (.alpha.1) of a first tire (3) of the vehicle; a second tire steering device (4) for setting a second predetermined steering angle (.alpha.2) of a second tire (5) of the vehicle; a first sensor device (6) for sensing a force which is necessary for setting the first predetermined steering angle (.alpha.1) of the first tire (3); a second sensor device (7) for sensing a force which is necessary for setting the second predetermined steering angle (.alpha.2) of the second tire (5); and an evaluation device (8) for determining the roadway coefficient of friction by evaluating the acquired data of the first and second sensor devices (6, 7) using a predetermined algorithm. The present invention also relates to a method for determining a roadway coefficient of friction.
