System and method for dynamically determining vehicle loading and vertical loading distance for use in a vehicle dynamic control system

摘要

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.
