Abstract
A start control system for a passenger protection system wherein after a first inflator has been fired, a detected deceleration of the vehicle is compared with a previously stored predetermined deceleration. Next, time integration is executed over an area in which the detected deceleration of the vehicle exceeds the previously stored predetermined deceleration if it has been decided that the detected deceleration of the vehicle exceeds the previously stored predetermined deceleration to increase speed reduction. Then, the time integral value is added to a speed integral value which is calculated as time integration of the detected deceleration of the vehicle until a point of time when it has been decided that the detected deceleration of the vehicle exceeds the previously stored predetermined deceleration. Finally, a start signal for a second inflator is output by a CPU to fire the second inflator when an added result exceeds a predetermined threshold value. As a result, even if stagnation of the speed integral value is caused, the second inflator can be fired without fail.
