Driving Scenario:
The vehicle speed around a curve exceeds the ability for the tires to 
hold the vehicle orientation, causing the vehicle to slide and begin to 
over-steer. The momentum of the load further pushes the coach, 
exacerbating the situation.
System Response:
The Bendix
®
 ESP
®
 stability system senses the driver’s intended path and 
compares it to the actual situation to identify an over-steer situation. In an 
attempt to correct the vehicle orientation and reduce speed if required, the 
system quickly applies braking pressure to only the appropriate wheels.
The Importance Of Full Stability... Bendix

 For Motor Coaches
Rollovers and loss-of-control situations happen in the blink of an eye. That's why a full stability system makes sense for motor coach applications. 
Stability for motor coaches needs to: 
1) Detect potential instability situations quickly and completely;
2) Intervene quickly and accurately; 
3) Apply ample braking where needed; and
4) Perform on wet, snow and ice covered surfaces.

Performance
 Enhancement
Driving Scenario:
A vehicle enters a curve too fast, on high friction pavement, resulting 
in high lateral (side) forces acting at the vehicles center of gravity (CG). 
The high friction between the wheels and the pavement create a 
“hinge” effect allowing the forces at the CG to push the vehicle over.
System Response:
The Bendix
®
 ESP
®
 stability system applies pressure to all coach brakes and 
reduces engine throttle to quickly reduce vehicle speed and therefore 
mitigate the tendency of the vehicle to roll over.
