Control system for actuating vehicle air-bags
First Claim
Patent Images
1. A control system for actuating a vehicle air-bag in response to detection of a collision of a vehicle, said system comprising:
- an acceleration sensor for producing an output signal representing an acceleration of the vehicle;
a processing means for producing data representing change in the detected vehicle speed calculated based on the acceleration sensed by said acceleration sensor;
a detecting means for detecting a temperature relating to that of the air-bag; and
a discriminating means responsive to said processing means and said detecting means for discriminating whether or not the collision has occurred by comparing the data with a reference signal which is determined in accordance with the detected temperature detected by said detecting means.

Abstract
In a control system for actuating a vehicle air-bag, a data representing change in the detected vehicle speed is calculated on the basis of the acceleration sensed by a vehicle acceleration sensor. The data is compared with a reference signal depending upon a temperature relating to that of an actuating member of the air-bag to discriminate whether or not the change in the detected vehicle speed has reached a level determined by the reference signal, whereby the complete inflation of the air-bag is ensured when a collision occurs without a time delay regardless of changes in temperature.
