Abstract:
1. A control unit for a roll control system for a vehicle suspension system, the control unit comprising: a valve body that is adapted to be connected to a roll control actuator device; a plurality of valves mounted upon said valve body, said valves operable to control said roll control actuator device with at least one of said valves being a solenoid valve; a housing removeably attached to said valve body; a circuit substrate mounted within said housing, said circuit substrate carrying said electronic components, said electronic components operable to selectively actuate said valves; at least one solenoid coil associated with said solenoid valve is carried by said circuit substrate, said solenoid coil being selectively energized by said electronic components to actuate said corresponding solenoid valve; a hydraulically actuated three-position four-way valve mounted upon said valve body, said three-position four-way valve adapted to be connected said roll control actuator device and operable to selectively actuate said roll control actuator device to counter vehicle roll; and two pairs of digital solenoid valves mounted upon said valve body, each of said valve pairs including a normally open valve and a normally closed valve, each of said valve pairs associated with one position of said three-position four-way valve and selectively operable to supply pressurized hydraulic fluid to said three-position four-way valve to change the position thereof.
