Abstract
An air bag restraint system and control system for controlling an air bag in a vehicle and compensating for ambient temperature variations. The control system includes a temperature sensor for sensing temperature of an air bag device, and an air bag controller for controlling actuation of an air bag. The controller controls restraining force produced by the air bag as a function of the sensed temperature. Accordingly, the air bag compensates to changes in temperature so as to optimize the air bag performance.
