Stability System Effectiveness

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 can not

provide braking force.

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.

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.
