ABSTRACT:
A system for controlling the hydraulically actuated components, including snow-ice control components carried by a truck. The system employs a hermetically secure composite housing mounted externally of the truck cab on the truck frame which retains a unique hydraulic reservoir in combination with a manifold supporting a plurality of solenoid actuated hydraulic valves and an associated electronic drive circuitry including a slave controller having a bidirectional data transmission port. That port communicates through a single bidirectional transmission bus with a master controller retained within an operator interface control console mounted in the truck cab. That control console also will contain a slave interface controller, as well as a slave datalog and communications controller.
