SYSTEM AND METHOD FOR DYNAMICALLY DETERMINING VEHICLE LOADING AND VERTICAL LOADING DISTANCE FOR USE IN A VEHICLE DYNAMIC CONTROL SYSTEM
First Claim
1. A method of controlling a safety system for a vehicle comprising:
- sensing a roll rate of said vehicle over time;
determining and updating a roll acceleration coefficient as a function of said roll rate so that said roll acceleration coefficient substantially includes the effect of each change of mass onboard said vehicle that occurs over time;
determining each said change in mass onboard said vehicle as a function of said roll acceleration coefficient; and
adaptively controlling said safety system substantially according to each said change in mass over time.

Abstract
A control system (18) and method for an automotive vehicle (10) includes a roll rate sensor (34) for generating a roll rate signal, a lateral acceleration sensor (32) for generating a lateral acceleration signal, a longitudinal acceleration sensor (36) for generating a longitudinal acceleration signal, and a yaw rate sensor (28) for generating a yaw rate signal. A safety device or system (44) and the sensors are coupled to a controller. The controller (26) determines an added mass and the height of the added mass on the vehicle, or a roll gradient, a roll acceleration coefficient, and/or a roll rate parameter that take into account the added mass and height from the roll rate, the lateral acceleration, the longitudinal acceleration, and the yaw rate of the vehicle, and controls the safety system in response thereto.
