Claims19
A suspension actuator system for a vehicle, comprising:
- an active control element communicating with a suspension control system to move a vehicle wheel in response to road conditions;
- a series passive control element comprising a first spring or damper mounted in series with the active control element;
- and
- a parallel passive control element comprising a second spring or damper mounted in parallel with the active control element, wherein the parallel passive control element comprises a spring having a rate of less than 3 N/mm.
1 more element
A suspension actuator system for a vehicle, comprising:
- a series passive control element comprising a first spring or damper;
- a parallel passive control element comprising a second spring or damper;
- an active control element communicating with a suspension control system to move a vehicle wheel in response to road conditions and comprising a processor configured to perform a method of:
- detecting movement of the vehicle on a roadway;
- determining when the vehicle requires active suspension control;
- and
- activating the active control element to move a wheel of the vehicle to smooth a vehicle ride, wherein the active control element comprises a motor mechanically connected to turn a ball nut assembly to move the wheel of the vehicle;
- wherein the series passive control element is mounted in series with the active control element and the parallel passive control element is mounted in parallel with the active control element.
