    Abstract: A vehicle safety system implements a method for helping to protect a vehicle occupant in the event of a frontal collision. The method includes determining a passive safety crash mode classification in response to crash signals received in response to the occurrence of a crash event. The method also includes determining an active safety crash mode classification in response to active safety signals received prior to the occurrence of the crash event. The method also includes determining an active safety confidence factor for the active safety crash mode classification. The method also includes determining the weighted crash mode classification as being the active crash mode classification in response to the active safety confidence factor exceeding a predetermined confidence value. The method further includes determining the weighted crash mode classification as being the passive crash mode classification in response to the active safety confidence factor not exceeding the predetermined confidence value.

    Abstract: A vehicle safety system for helping to protect a vehicle occupant in the event of a frontal collision includes a controller, one or more crash sensors for sensing a frontal collision, and an active sensor for detecting objects in the path of the vehicle. The controller is configured to implement crash discrimination metrics that detect the occurrence of a frontal collision in response to signals received from the crash sensors. The crash discrimination metrics implement thresholds for determining whether the signals received from the crash sensors indicate the occurrence of a frontal collision. The controller is configured to implement an algorithm that uses information obtained from the active sensor to detect an object in the path of the vehicle and to select the thresholds implemented in the crash discrimination metrics in response to detecting the object.

    Abstract: A method for controlling an actuatable safety device (110) for helping to protect a vehicle occupant includes sensing left-front and right-front pressure values via a pressure tube sensor (18). The method also includes executing pressure tube metrics that evaluate the left-front and right-front pressure values and selecting switched crash thresholds in response to the pressure tube metrics. The method also includes sensing vehicle acceleration parameters (99) and executing one or more crash metrics that evaluate the vehicle acceleration parameters to determine whether the switched crash thresholds are exceeded. The method further includes controlling deployment of the actuatable safety device (110) in response to determining that the switched crash thresholds are exceeded. A vehicle safety system (100) implements the method.
