ABSTRACT:
A physical quantity control device includes first and second control elements having different sensitivities from one another, the first and second control elements providing outputs to change at least one physical quantity in response to first and second operational quantities individually input to the first and second control elements. First and second computing circuits are provided for computing the first and second operational quantities in response to a deviation between a predetermined target value and the physical quantity, wherein the physical quantity is feedback controlled to converge with the predetermined target value. Further, first and second filters for passing frequencies individually corresponding to the sensitivies of the first and second control elements, respectively, the first filter being provided in a feedback loop including the first control elements and the first computing circuit, and the second filter being provided in a second feedback loop including the second control element and the second computing circuit. Further, the output of the first and second control elements is preferably input to an operation means to generate the physical quantity, wherein the physical quantity controlled is a vehicle motion.
