Method and system for intention estimation and operation assistance
First Claim
1. A method for operating a driver'"'"'s intention estimation system for estimating a driver'"'"'s intention, wherein the system includes a microprocessor which, upon execution of software, controls the system to perform functions prescribed by the software, the method comprising the steps of:
- detecting an operation of a real driver of a vehicle;
calculating an operation of each of a plurality of imaginary drivers to accomplish a respective associated intention according to a real-time vehicle driving condition and a respective associated intention of each imaginary driver;
calculating a respective likelihood value for each of the plurality of imaginary drivers based on the detected operation of the real driver and the operation of each of the plurality of imaginary drivers; and
determining an estimated intention of the real driver based on the respective likelihood value of each of the plurality of imaginary drivers with the respective associated intention.

Abstract
An intention estimation and operation assistance system for estimating an operator'"'"'s intention and providing assistance to operation of a machine. Reference data, such as the operation of a plurality of hypothetical operators, is provided for comparison with the operation of a real operator, to determine an estimated intention of the operator. The estimated operator is utilized to alter the operation of the machine, to provide a safer and/or smoother operation experience in operating the machine.
