Definitions
- the signal generated will indicate the presence or absence and location of the occupant and is another of the vehicle parameters signals.
- the first sensor 20 is a proximity or reflective capacitive sensor and the second sensor 22 is an infrared sensor.
- Other forms of such sensors include ultra sound sensors and photographic sensors.
- All of the vehicle parameter signals are electrically connected to an electronic control unit (ECU) 28 for generating the electrical firing signal to the inflator means 1 2.
- ECU electronice control unit
- the ECU 28 there are many parameters stored to modify, according to an algorithm, the mixing of the vehicle parameter signals to generate the proper and correct firing signal. It is a function of the ECU 28 and its contents to make the overall system and adaptive or intelligent system for use in a motor vehicle.
- some of the vehicle parameter signals will function to halt or not initiate deployment of the restraint means 1 4 while some other vehicle parameter signals, along with the algorithms in the ECU 28 will function to release the inflatable gas to controllably inflate the restraint means 1 4.
- the signal in effect conditions the ECU to begin preparation of the deployment of the proper restraint means 1 4 such as an air bag, either frontal or either side air bag, or any combination thereof.
- the proper restraint means 1 4 such as an air bag, either frontal or either side air bag, or any combination thereof.
- another first sensor maybe located on the door of the vehicle to function to determine if the occupant is leaning against the door or is in close proximity thereto.
