Patent ID: 7460936

Claim:
A control system for controlling energization of a plurality of valves in a hydraulic system, the control system comprising: a plurality of sensors; a signal processing circuit coupled to the plurality of sensors for determining a desired energization of the plurality of valves dependent upon measurements by at least a portion of the plurality of sensors; and a driver circuit coupled to the signal processing circuit for generating, responsive to the desired energization of the plurality of valves as determined by the signal processing circuit, a control signal to energize the plurality of valves to the desired energization, wherein the plurality of sensors includes; a steering angle sensor for measuring a parameter indicative of an angular orientation of a vehicle steering mechanism; a road speed sensor for measuring a parameter indicative of vehicle road speed; a lean position sensor for measuring a parameter indicative of a lean angle of at least a portion of the vehicle; and wherein the signal processing circuit includes; a value generating circuit configured to process an output of the steering angle sensor and an output of the road speed sensor, to provide an output indicative of a desired lean angle of the at least a portion of the vehicle; a filter configured to process an output of the value generating circuit; a first summing junction configured to process an output of the filter and an output of the least position sensor, to provide an output comprising a difference between the output of the filter and the output of the lean position sensor; an amplifier element configured to process the output of the first summing junction, to provide a tunable gain to the output of the first summing junction; and a second summing junction configured to sum an output of the amplifier element and an output of at least one other element to provide a summing junction output for use in generating the control signal to energize the plurality of valves.
