Stability System Effectiveness
Next, during high-speed maneuvers in potential rollover
situations, the tandem tires of the tractor and trailer
can lift off the ground. If that occurs, the steer axle
brakes contribute a much larger percentage of available
braking capacity because the wheels that are no longer
in contact with the road surface cannot provide braking
force.
Third, the ability to apply steer axle brakes individually
is a fundamental requirement for yaw (spin) control.
By applying brakes at any one or all of a vehicle’s “Four
Corners,” the stability system may be able to correct
the vehicle’s orientation, mitigating the potential for a
jackknife, spin out or slide.
Finally, with the potential regulatory requirements for
larger front brakes in the future, the steer axle’s braking
contribution to a vehicle’s overall braking capacity and
potential stability margin is expected to increase.
ABS / stability system interaction
With Bendix Advanced ABS, the ABS system is given
“priority” at the wheel ends to manage wheel slip for
optimal braking. The ABS system functions similarly
whether the stability system or the driver applies the
brakes.
