Active Wheel Speed Sensors (aWSS)
Advanced measurement accuracy enables precise vehicle position determination
Key Facts
What can Active Wheel Speed Sensors (aWSS) provide?
Designed for demanding commercial vehicle applications, the improved measurement precision of ZF’s active wheel speed sensor contributes significantly to the accuracy of brake control interventions and ADAS functions for higher automation levels. Building on ZF’s decades of experience in developing, manufacturing and marketing millions of wheel speed sensors, the active wheel speed sensor matches the mounting of ZF’s passive wheel speed sensors to allow for simplified adoption.
