First Claim
Patent Images
1. An active suspension system suitable for use with a vehicle, comprising:
- a passive suspension element having a first end adapted for rigid engagement to a sprung mass of the vehicle and a second end adapted for rigid engagement to an unsprung mass of the vehicle, the passive suspension element being configured for applying a passive force to the sprung mass; and
an active suspension element including a linear switched reluctance actuator having a first end adapted for rigid engagement to the sprung mass of the vehicle and a second end adapted for rigid engagement to the unsprung mass of the vehicle wherein the linear switched reluctance actuator is configured for applying an active force to the sprung mass to substantially maintain a predetermined vertical orientation of the sprung mass when the vehicle traverses a road irregularity.
