Abstract:
A device for performing an impact detection in a vehicle, comprising:a processor; at least one impact sensor; a memory; and at least one precrash sensor that is connectable to the at least one impact sensor, the processor determining a time of impact as a function of first signals of the at least one precrash sensor, wherein: the processor lowers a noise threshold for the at least one impact sensor, the processor then determines a deployment time for a restraint device connected to the device as a function of the first signals and second signals of the at least one impact sensor, the processor loads a continuous threshold value function from the memory for a set of features derived by the processor from the second signals, and the processor compares the set of features with the continuous threshold value function as a function of the first signals to determine the deployment time.
