Note: Modern ABS systems cycle at 10-15 Hz. The optimal slip ratio for maximum friction on dry pavement is approximately 10-20%.
Reference
Wheel RPM = (Speed x 5280 x 12 / 60) / Tire Circumference
Sensor Frequency = Wheel RPM x Teeth / 60
Slip Speed = Vehicle Speed x Slip Ratio
ABS Cycle Rate typically 4-20 Hz
Optimal slip ratio: 10-20% for maximum grip
