WHEEL SPEED SENSOR AND WHEEL SPEED SENSING SYSTEM
First Claim
1. A Wheel speed sensor, comprisingan encoder wheel having a number of poles,a sensing unit for sensing a signal dependant on a rotation angle of the encoder wheel, anda sending unit being connected with the sensing unit,wherein the sending unit is configured to send data packets of a first type that are indicative for a respective pole transition at the sensing unit,characterized in thatthe sending unit is further configured to send data packets of a second type that are indicative for an amplitude of the signal.
