Abstract
An apparatus for controlling an occupant restraint system, such as an air bag (102), includes sensors (30, 36, 60, 64, 70, 80, 84, 86, 88, 90, 502, 504, 506) for sensing at least two parameters that could affect an occupant restraining function of the restraint system. The sensors are connected to a controller (24). A regulating valve (120) is connected to a reaction can (103) of the air bag (102) and is controlled by a control signal from the controller (24). The controller (24) selects one of a plurality of discrete control zones dependant upon the at least two sensed parameters and provides the control signal based on the selected one of the discrete control zones.
