The ABS — EBL braking system is available as an alternative to the EBS system on 4x2 e 6x2 vehicles.
ABS Anti — Lock Brake System
Braking a moving vehicle and is deceleration and stopping distance are essentially dependant on adherence between tire and road
surface. Improved braking with an efficient braking system can only be achieved by acting on tire friction features or road surface
quality.
Even in optimum conditions, absolutely safe braking is not guaranteed when critical situations have to be coped with, such as
low adherence due on a wet or iced road surface, which obliges the vehicle operator to moderate braking action to prevent
possible wheel locks and consequent dangerous loss of vehicle control.
The ABS therefore has the function of ensuring vehicle stability in any braking condition by preventing wheel locks independently
of road surface conditions and guarantee full exploitation of available adherence.
The system enables maintaining direction control even in emergency braking and acting on the steering wheel to avoid obstacles
with danger of vehicle control loss.
In essence, the ABS system:
-
prevents wheel locks during vehicle braking in and road adherence conditions
-
reduces stop distances
-
offers operator safety for stability and vehicle control maintenance.
Electronic Brakes Limiter EBL
The EBL function controls rear axle wheel skidding by comparing it with front wheel speed. Data entering the center are wheel
rpm and braking pressure measured by the pressure sensor installed upstream the rear axle ABS modulators. The center uses
these data to calculate vehicle speed and deceleration, rear axle wheel skid and minimum deceleration required. The EBL function
is activated with rear ABS modulators maintaining set pressure when the operators applies excess braking force than required
for vehicle load conditions, in essence when vehicle deceleration and rear axle skid thresholds are passed.
