Abstract: A self-diagnosing sensor system for a vehicle is provided. The vehicle has a bumper with fascia material. The sensor system includes an elongated, deflectable cable disposed in the bumper generally adjacent to the fascia material. A tensioning and sensing unit is coupled to each end of the cable and fixed to the vehicle. Each unit includes a tension sensor electrically connected with an ECU of the vehicle such that the ECU receives signals from the tension sensors regarding tension in the cable, indicative of 1) whether the bumper has been impacted based on deflection of the cable from a sensing position, or 2) whether damage to the cable or a tensioning and sensing unit has occurred.

Abstract: The present invention relates to an elastic bearing element (1) having at least one first body (11), having at least one second body (12), and having at least one elastomer element (10) arranged in the direction of a force flow between the first body (11) and the second body (12), furthermore having at least one sensor (2) configured and arranged to detect directly or indirectly a force in the force flow between the first body (11) and the second body (12).

Abstract: A crash box arrangement includes a hollow member having a first hardness and defining a hollow space in communication with at least one ventilation opening; and a damper having a second hardness which is smaller than the first hardness. The damper has an impulse cavity in communication with the hollow space of the hollow member.

Abstract: A distributed sensing system and method improves sensing of events that may require restraint deployment in a vehicle by distinguishing between deployment events and non-deployment events using data from more than one sensor. A transmission check process continuously monitors an incoming signal from a sensor and counts the number of data samples that exceed a selected value using a counter. If the counter value exceeds a selected threshold, the system indicates that the transmission check is fulfilled and allows deployment of the restraint. A correlation acceleration difference (CAD) algorithm calculates a CAD term corresponding to a degree of intrusion of a foreign object into a vehicle at a given time. Acceleration data from sensors disposed at supporting sides of the vehicle are checked if they respond to an event, and the absolute values of the acceleration data are subtracted from each other to obtain an absolute difference from which the CAD term is calculated.

Abstract: An air bag system (12) provides a central controller (14), a multiple of satellite sensors (16) and a multiple of deployable air bags (18). The central controller (14) runs the impact event algorithms. The number of satellites which are allowed to activate algorithms at any one time is limited. The minimum number of satellites required for full protection is the maximum number of satellite sensors allowed to wake up an impact event algorithm at any one time. An order for algorithm wake is also specified since the number of algorithms allowed is less than the total number of satellite sensors.
