Abstract
A computerized control system controls a hydraulic subsystem of an articulated dump truck. Among other possible equipment, the hydraulic subsystem controls the raising and lowering of the dump truck bed. The control system detects a side-to-side lean angle of the dump truck. Upon the dump truck leaning at or above a predetermined lean angle, the control system controls the hydraulic subsystem to automatically lower the dump truck bed. In various aspects, the predetermined lean angle may be preprogrammed, may be programmable by the truck operator, or may be programmable only by certain personnel (e.g., changing the lean angle may require entry of a password). In one aspect, a manual override switch prevents automatic lowering of the dump truck bed when the dump truck is leaning at or above the predetermined lean angle.
