Operation
!
As the ABS sensor rotor rotates, the magnetic flux between the ABS wheel speed sensor and the ABS sensor
rotor change periodically. This periodic change is in proportion to the rotation speed.
!
The semiconductor element in the wheel speed sensor detects the change in magnetic flux, and the active
drive circuit converts it to a rectangular wave signal for the current, which is transmitted to the DSC HU/CM.
!
For every single rotation of the ABS sensor rotor, 44 rectangular wave pulse signals are output. The CM in the
DSC HU/CM calculates the wheel speed from the periodicity of these pulses.
