Claim 8:
9. A method of operating a hydraulic actuator with a dynamically variable motion ratio, operationally interposed between a vehicle body and a wheel assembly of a vehicle, wherein the actuator includes a piston, attached to a piston rod, slidably received in a hydraulic cylinder and dividing the hydraulic cylinder into a first chamber and a second chamber, and wherein the hydraulic actuator is exposed to an oscillating input at a frequency above and below a threshold frequency, the method comprising:
with a hydraulic restriction, modifying a compliance of a first chamber side flow path relative to a second chamber side flow path, wherein the first chamber side flow path allows fluid exchange between the first chamber and a first port of a hydraulic pump, wherein the second chamber side flow path allows fluid exchange between the second chamber and a second port of the hydraulic pump; and
inducing a change in the motion ratio of the actuator as a function of the frequency of the oscillating input relative to a threshold frequency, wherein the threshold frequency is a wheel hop frequency of a wheel associated with the wheel assembly.
