Abstract
A system and method that establishes a confidence in a vehicle position determined by a vehicle position determination system and uses the established confidence to change a behavior of an active suspension system of a plant in the vehicle.
Claims17
A method of operating an actuator of an active suspension system in a vehicle, the method comprising:
- determining an approximate location of the vehicle;
- calculating a level of confidence associated with the determined vehicle location;
- and
- controlling, based at least in part on the calculated level of confidence and the determined location, a force output by the actuator of the active suspension system.

A method for controlling a suspension system that suspends a vehicle body relative to a wheel of a vehicle, the method comprising:
- (a) determining a location of the vehicle;
- (b) calculating a level of confidence in the determined vehicle location;
- and
- (c) adjusting, based at least in part on the level of confidence, an operating parameter of the suspension system.
1 more element
A suspension system for suspending a vehicle body relative to a wheel of a vehicle, the suspension system comprising:
- a non-transitory memory that stores road trajectory information;
- a vehicle position determination system configured to determine an approximate location of the vehicle;
- and
- a controller that receives data from, the memory and from the vehicle position determination system, wherein the controller is configured to:
- predict, based at least in part on the approximate location of the vehicle and a portion of the road trajectory information stored in the memory, an upcoming road trajectory;
- calculate a level of confidence associated with the approximate location of the vehicle and/or the predicted upcoming road trajectory;
- determine, based at least in part on the first level of confidence and the predicted upcoming road trajectory, a desired value of an operating parameter of the suspension system.
