A method and a device for measuring the angle of a rotatable body, in particular a body rotatable by more than 360.degree., are described. In this case this rotatable body cooperates with at least two further rotatable bodies, for example gear wheels, whose angular positions are determined with the aid of two sensors. The angular position of the rotatable body is determined from the angular positions detected in this way. So that unequivocal statements can be made, it is necessary for all three rotatable bodies or gear wheels to have defined predetermined numbers of teeth. The method and the device can be used, for example, for determining the steering angle of a motor vehicle.

[ We claim:] [1.] A method for measuring the angle of a rotatable body, in particular a body which can be rotated by more than 360.degree., which has a number of uniform angular markers or teeth and cooperates with at least two further rotatable bodies, which have another number of uniform angular markers or teeth, characterized in that the angles .theta. and .psi. of the two further rotatable bodies are determined and the angular position .phi. of the rotatable body whose angle is to be measured is calculated from the angles .theta. and .psi., taking into consideration the prevailing geometric conditions.
