In a method for controlling the release of a passenger restraint system in a vehicle, an acceleration signal is measured and integrated with respect to time to obtain a velocity signal. A release threshold value for the velocity signal is determined. If the velocity signal then falls below the release threshold value, thus indicating a vehicle collision, the passenger restraint system is released. The release threshold value is controlled depending on the type of accident situation and upon the operating parameters of the vehicle to increase the release sensitivity of the passenger restraint system. For example, the release threshold value is adjusted based on the value of the velocity signal. If the velocity signal decreases in value, then the release threshold is lowered to a more sensitive value.
