Benefits of Trailer ABS
ABS-controlled trailer braking ensures optimum vehicle
stability while minimizing the stopping distance. During
vehicle operation, the trailer ABS Electronic Control Unit
(ECU) continuously monitors all wheel speed sensors. Data
input from the wheel speed sensors allows the ECU to:
•
Detect impending wheel lock.
•
Maintain optimum wheel slip.
•
Maximize overall braking effectiveness.
•
Minimize tendencies for trailer swing out during hard
braking conditions.
