Patent ID: 7185449

Claim:
A system for controlling the hydraulic actuated components, including snow-ice control components mountable upon a truck having a wheel supported frame, an internal combustion engine, a cab, a support portion configured to receive a load, and a hydraulic pump connected in driven relationship with said engine having a pump output and input, said truck being movable along a roadway at given velocities, comprising: an operator accessible process controller assembly mounted within said cab having an operator interface portion with a display and one or more manually controllable switch components actuable to provide command inputs to effect control of said hydraulically actuated components, said process controller assembly being connected with a source of electrical power and having a process controller assembly bidirectional data transmission port; a hermetically secure composite assembly supported from said frame comprising a hydraulic fluid reservoir portion having a fluid level and a suction outlet connectable in fluid transfer relationship with said pump input, further comprising a manifold portion supporting a plurality of electrically actuated hydraulic valves coupled in fluid transfer relationship with said pump output and said hydraulically actuated components and actuateable in response to control inputs, said composite assembly having a composible control assembly including a composite assembly controller responsive to said command inputs to provide composite assembly controller outputs deriving said control inputs to said electrically actuated hydraulic valves, said control assembly being connected with a source of electrical power and said composite assembly controller having a bidirectional transmission port; a hydraulic return conduiting assembly coupled in fluid flow communication between said composite assembly hydraulic fluid reservoir portion and said hydraulically actuated components; and a bidirectional data transmission bus assembly coupled in command input conveying relationship between said controller assembly bidirectional data transmission port and said composite assembly controller bidirectional transmission port.
