ABS COMPONENT FUNCTIONS
Wheel sensors and wheel sensor rotors
Wheel sensors “1” detect the wheel speed and transmit the rotation signal to the ABS ECU.
Each wheel sensor is composed of a permanent magnet and a hall IC. The sensor rotors “2” rotate with
the wheels. The sensor rotors “2” have 40 slots and are installed close to the wheel sensors. As the
sensor rotor rotates, the hall element in the hall IC installed in the wheel sensor generates pulses. The
pulse frequency, which is proportional to the wheel speed, is converted into a wave in the hall IC so that
it can be output.
The ABS ECU calculates the wheel rotation speed by detecting the pulse frequency.
