Abstract
An intelligent boom control hydraulic system with a straight-line feature, for a feller buncher is disclosed. The system comprises a hoist hydraulic cylinder, a stick hydraulic cylinder, a hoist boom position sensor, a stick boom position sensor, a hydraulic fluid pump, a hydraulic reservoir including hydraulic fluid, and various valves. A hoist control valve controls flow from the hydraulic pump to the hoist hydraulic cylinder, and the hoist hydraulic cylinder to the hydraulic reservoir. A stick control valve controls flow from the hydraulic pump stick hydraulic cylinder, and the stick hydraulic cylinder to the hydraulic reservoir. A straight-line control valve the hoist hydraulic cylinder and the stick hydraulic cylinder. A microprocessor directs sends signals to control the hydraulic fluid flow through control valves based on target hoist stick boom velocities and a look up chart to select valve combinations to achieve the target hoist and stick boom velocities.
