Abstract :
Magnetic sensor systems are widely used for contact-free speed detection in the automotive industry. State-of-the-art speed measurements are typically performed using magnetic pole wheels that require extensive signal post processing to compensate for imperfections like noise, manufacturing intolerances, vibration and stagger. Some applications such as tire pressure monitoring, tire-road friction measurements and Anti-locking Brake Systems (ABS) demand a high degree of accuracy in the signal. An alternative pole wheel structure is proposed in this paper, which improves the characteristics of the signal measurements significantly.
