SYSTEM AND METHOD FOR QUALITATIVELY DETERMINING VEHICLE LOADING CONDITIONS
First Claim
1. A method of controlling a safety system for a vehicle comprising the steps of:
- determining a roll rate signal indicative of a roll rate of said vehicle;
operating a load change detector to indirectly determine a potential load change onboard said vehicle according to signals received from at least one device selected from the group consisting of a door sensor, a tailgate sensor, a longitudinal acceleration sensor, a transmission sensor, a transmission controller, an accelerator pedal sensor, a throttle position sensor, a throttle signal generator, a brake pedal sensor, and a brake signal generator;
determining a change in loading mass onboard said vehicle from said roll rate signal and said potential load change; and
adaptively controlling the safety system in response to the change in loading mass.

Abstract
A control system (18) and method for an automotive vehicle (10) includes a controller (26) that determines whether or not a potential load change has occurred in a load change detector (59). A load change detector (59) may be coupled to various sensors to determine whether or not a change in load has occurred. If a change in load has occurred an adaptively determined roll condition parameter such as a roll acceleration coefficient, a roll rate parameter or a roll gradient may be reset. If a potential load change has not occurred, then a newly determined value for an adaptive roll condition may be included in a revised adaptive roll condition average. A safety device (44) may be controlled in response to the revised adaptive roll condition.
