Abstract
The invention relates to a method for activating a safety device, using a first impact sensor for generating a displacement signal which reproduces the movement of the vehicle in a direction of displacement, and a second impact sensor, arranged at a distance from the first impact sensor, for generating a displacement signal which reproduces the movement of the vehicle in the same direction of displacement. A processing device is provided, by which means the two displacement signals or signals derived therefrom can be correlated at the right time, and by which means the safety device is activated according to the predetermined correlations of the two signals.
Claims11
A method of activating a safety device, the method comprising the acts of:
- generating a displacement signal with a first impact sensor, which displacement signal reflects a movement of the vehicle in a direction of displacement;
- generating a second displacement signal with a second impact sensor, arranged at a location spaced apart from the first impact sensor, which second displacement signal reproduces the movement of the vehicle in the same direction of displacement;
- correlating the first and second displacement signals, or signals derived therefrom, with a processor in a substantially isochronous manner;
- and
- activating the safety device according to predetermined correlations of the first and second displacement signals.
