Determination of vehicle payload condition
First Claim
1. A method of determining a vehicle payload condition, the method comprising;
- determining a first payload-state parameter, a second payload-state parameter, and at least one roll variable;
determining a first differential based on the first payload-state parameter and the second payload-state parameter;
determining a second differential based on the first payload-state parameter and the roll value;
determining a multiplier;
determining a payload estimate based on the first payload differential, the second payload differential, and the multiplier.

Abstract
The invention provides a method, a computer usable medium including a program, and a system for determining a vehicle payload condition. The method and computer usable medium include the steps of determining a first payload-state parameter, a second payload-state parameter, and at least one roll value. A first differential is determined based on the first payload-state parameter and the second payload-state parameter. A second differential is determined based on the first payload-state parameter and the roll value. A multiplier is determined. A payload estimate is determined based on the first payload differential, the second payload differential, and the multiplier. The system includes means for achieving the method steps of the invention.
