Abstract
A control system for a vehicle having a loader arm, such as a skid steer loader, telescopic handler, wheel loader, backhoe loader or forklift, reads a load height sensor, a load weight sensor; dynamically calculates the static center of gravity of the combined vehicle and load; calculates the acceleration necessary to cause the dynamic center of gravity of the combined vehicle and load to extend exterior of the vehicle's stability polygon; and limits the acceleration of the vehicle to less than the acceleration necessary to cause the dynamic center of gravity of the combined vehicle and load to extend exterior of the vehicle's stability polygon.
