1. A system for estimating an intention of a driver of a vehicle, comprising:
- a detector configured to detect a driving status of the vehicle, a state of environment around the vehicle, and an operation performed by the driver; and
an intention estimation device configured to;
calculate a likelihood value of each of a plurality of hypothetical intentions of the driver to operate the vehicle based on the detected operation performed by the driver the detected state of environment and the operation performed by the driver, and the detected driving status of the vehicle; and
select one of the hypothetical intentions as an estimated intention of the driver based on calculated likelihood values of the plurality of hypothetical intentions and a criterion for estimating the driver'"'"'s intention,wherein the intention estimation device includes an adjuster configured to adjust the criterion according to at least one of the detected state of environment and the detected driving status of the vehicle.

Abstract
Intention estimation methods and systems that are adaptive to changes in environment and/or operations are disclosed. An exemplary system includes a detector configured to detect at least one of a state of environment around a vehicle, and an operation performed by the driver of the vehicle. An intention estimation device is provided to generate an estimated intention of the driver based on the detected operation performed by the driver and an adjustable criterion.
