Abstract
A method and apparatus for measuring unbalance of a vehicle wheel that is freely rotatable and mounted on a motor vehicle. The wheel is rotated during the measuring operation at a measurement speed and a mark on the wheel is sensed to provide accurate information concerning the angular wheel position of the rotating wheel. An incremental generator is operatively associated with the wheel for supplying a predetermined number of increments between each two sensings of the mark on the wheel, which is associated with a rotational angle of 360.degree.. The respective counter condition is used for detecting the rotational angle of the wheel.
