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 locations.
Claims16
A method for operating a vehicle on a road segment including vertical disturbances, said vehicle comprising a payload compartment, a road engaging device, a controllable suspension element and at least one sensor, for sensing said vertical disturbances, said method comprising:
- receiving data specifically representative of one of said vertical disturbances;
- and
- commanding said controllable suspension element to exert a force between said payload compartment and said road engaging device in accordance with said data specifically representative of said one vertical disturbance, said force changing the distance between said payload compartment and said road engaging device, before said road engaging device encounters said one vertical disturbance.
A vehicle for operating on a road segment including vertical disturbances, comprising:
- a payload compartment;
- a road engaging device;
- a controllable suspension element;
- and
- a microprocessor for commanding said controllable suspension element to exert a force between said payload compartment and said road engaging device in accordance with data specifically representative of one of said vertical disturbances, said force changing the distance between said payload compartment and said road engaging device, before said road engaging device encounters said one vertical disturbance.
A vehicle for operating on a road segment including vertical disturbances, comprising:
- means for supporting a payload;
- means for engaging the road segment;
- controllable means for suspending said payload compartment;
- and
- means for commanding said controllable suspending means to exert a force between said means for supporting the payload and said means for engaging the road segment in accordance with data specifically representative of one of said vertical disturbances before said road engaging means encounters said one vertical disturbance, said force changing the distance between said means for supporting the payload and said means for engaging the road.
