Abstract
A method is provided for triggering a vehicle occupant restraint device, in which a sensor signal generated by a crash sensor is fed to a triggering device and to a clearing device supplying a clearing signal. The sensor signal is integrated in the clearing device and subjected to an examination algorithm. The output signal of at least one additional crash sensor is fed to the clearing device. Then, the two output signals are linked to one another and are subsequently integrated during an observation period. A clearing signal is generated when the integral exceeds a threshold value.
Claims8
A method of triggering a vehicle occupant restraint device, the method comprising the acts of:
- generating a sensor signal by a first crash sensor and feeding the sensor signal to a triggering device via a clearing device that supplies a clearing signal, in which clearing device the sensor signal is integrated and subjected to an examination algorithm;
- generating an output signal of at least one additional crash sensor and feeding the output signal to the clearing device;
- linking the sensor signal and the output signal to one another and subsequently mathematically integrating the linked sensor and output signals into an mathematically integrated output during an observation period;
- and
- generating the clearing signal when the mathematically integrated output exceeds a defined threshold value.
