Wheel Sensor and Sensor Rotor
FUNCTIONS WITHIN THE SYSTEM
Wheel sensor and sensor rotor detect each wheel speed. And wheel sensor inputs wheel speed signal to ABS actuator and electric unit (control unit).
INDIVIDUAL FUNCTIONS WITHIN THE SYSTEM
The wheel sensor reads a magnetic field change.
INDIVIDUAL OPERATION
- Downsize and weight reduction is aimed. IC for detection portion and magnet for sensor rotor are adopted.
- Power supply is supplied to detection portion so that magnetic field line is read. Magnetic field that is detected is converted to current signal.
- When sensor rotor rotates, magnetic field changes. Magnetic field change is converted to current signals (rectangular wave) and is transmitted to ABS actuator and electric unit (control unit). Change of magnetic field is proportional to wheel speed.
