Abstract
The invention provides a load determining system including a sensorized rolling element bearing in a hub unit for wheels. The bearing includes a first ring and a second ring as an inner ring and an outer ring. Either one of the first and second ring may be the inner ring, the other ring being the outer ring. The system includes at least one magnetic sensor attached to the first ring that interacts with a target wheel attached to the second ring. Further, the system includes a signal processing unit configured to receive the magnetic sensor output of the at least one magnetic sensor. The signal processing unit is configured to determine at least axial forces acting on the bearing based on the amplitude of the magnetic sensor output. It is proposed that a pitch wavelength of the target ring is 4 mm or less.
