摘要： A suspension actuator includes an upper mount, a lower mount, a first actuator mechanism, and a second actuator mechanism. The upper mount is connectable to a sprung mass of a vehicle. The lower mount is connectable to an unsprung mass of the vehicle. The first actuator mechanism forms a first load path between the upper mount and the lower mount. The first actuator mechanism is one of an electromagnetic linear actuator mechanism or a ball screw actuator mechanism. The second actuator mechanism forms a second load path in parallel with the first load path between the upper mount and the lower mount. The second actuator mechanism is one of a mechanical linear actuator mechanism, an air spring actuator mechanism, or a hydraulic actuator mechanism.

摘要： A state module selectively sets a present state to a first state in a predetermined order of states; a valve control module determines first target open and closed states for valves of a suspension system based on the present state and opens and closes the valves according to the first target open and closed states, respectively; a pump control module configured to, when the valves are in the first target open and closed states, respectively, selectively operate an electric pump of the suspension system in a first direction and pump hydraulic fluid toward the suspension system; and a diagnosis module configured to: record first and second values of pressures within the suspension system measured using pressure sensors, respectively, before and after the operation of the electric pump in the first direction, respectively; and selectively diagnose faults in a first subset of the valves based on whether pressure increases occurred.

摘要： At least one controller configured to control an actuator of an active suspension system. The at least one controller includes circuitry configured to determine an actuator state, and apply the actuator state and a commanded state to an inverse model of the actuator to produce an actuator command. The circuitry is configured to produce the actuator command by a process that includes performing low pass filtering and phase compensation to correct a phase introduced by the low pass filtering.
