System for dynamically determining vehicle rear/trunk loading for use in a vehicle control system
First Claim
1. A method of controlling a vehicle system for a vehicle comprising:
- determining a pitch gradient;
determining a pitch acceleration coefficient;
determining an added mass and a position of the added mass from the pitch gradient and the pitch acceleration coefficient; and
controlling the vehicle system in response to the added mass and position of the added mass.

Abstract
A control system (18) and method for an automotive vehicle (10) includes a pitch rate sensor (37) generating a pitch rate signal, a longitudinal acceleration sensor (36) generating a longitudinal acceleration signal, and a yaw rate sensor (28) generating a yaw rate signal. A safety system (44) and the sensors are coupled to a controller. From the sensors, the controller (26) determines an added mass and a position of the added mass, a pitch gradient and/or a pitch acceleration coefficient that takes into account the added mass and position. The controller controls a vehicle system in response to the added mass and the position of the added mass, the pitch gradient and/or pitch acceleration coefficient variables.
