System and method for qualitatively determining vehicle loading conditions
First Claim
1. A method of controlling a safety system for a vehicle, said method comprising the steps of:
- (a) 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;
(b) adjusting a control system to determine a revised adaptive roll condition parameter in response to said potential load change; and
(c) adjusting the control system to control said safety system in response to said revised adaptive roll condition parameter.

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.
