Abstract
An active suspension system for a vehicle including elements for developing and executing a trajectory plan responsive to the path on which the vehicle is traveling. The system may include a location system for locating the vehicle, and a system for retrieving a road profile corresponding to the vehicle location.
Claims18
Apparatus for a surface vehicle for operating on a path, said path comprising vertical disturbances, said apparatus comprising:
- a controllable suspension for applying a force between a payload compartment and a surface engaging device;
- and
- a trajectory developing system operatively coupled to said controllable suspension, said trajectory developing system for developing a trajectory plan responsive to data specifically representative of said vertical disturbances.
A method for operating an active vehicle suspension system in a surface vehicle on a surface having vertical disturbances comprising:
- determining the location of said surface vehicle;
- and
- determining if there is a vertical trajectory plan corresponding to said location, said trajectory plan corresponding to data specifically representative of said vertical disturbances.
Apparatus for a surface vehicle comprising:
- an active suspension;
- a locator system for determining the location of said surface vehicle;
- a trajectory plan storage device, for storing trajectory plans corresponding to locations, said trajectory plans corresponding to data specifically representative of vertical disturbances on a surface on which said surface vehicle is traveling;
- and
- a trajectory plan microprocessor for determining if said trajectory plans contain a trajectory plan corresponding to said determined location.
