Abstract
A rotational direction detector is specified which is provided for mounting to a circumferential segment of a wheel having at least one sensor, wherein a change in the output signal of the sensor occurs when the circumferential segment enters and/or leaves the wheel contact area. Furthermore a method is specified for determining the direction of rotation of a wheel, wherein the signal change is determined and a rotational direction signal is derived therefrom.

A rotational direction detector provided for mounting to a circumferential segment of a wheel, the rotational direction detector comprising:
- at least one sensor, wherein a change in an output signal of said sensor occurs when the circumferential segment at least one of enters and leaves a wheel contact area.
A method for determining a rotational direction of a wheel, which comprises the steps:
- determining a signal change of at least one sensor disposed on a circumferential segment which occurs due to the circumferential segment at least one of entering and leaving a wheel contact area;
- and
- deriving a rotational direction signal from the signal of the at least one sensor.
