Method and apparatus for providing a safing function in a restraining system

An apparatus ( 10 ) is provided for controlling an actuatable restraint ( 14, 16 ) in a vehicle ( 12 ). An sensor ( 24 ) is mounted in the vehicle ( 12 ) and outputs an electrical signal having a characteristic indicative of a vehicle event. A discrimination circuit ( 42 ) is coupled to the sensor (...

Zusammenfassung:An apparatus ( 10 ) is provided for controlling an actuatable restraint ( 14, 16 ) in a vehicle ( 12 ). An sensor ( 24 ) is mounted in the vehicle ( 12 ) and outputs an electrical signal having a characteristic indicative of a vehicle event. A discrimination circuit ( 42 ) is coupled to the sensor ( 24 ) and determines if a predetermined event occurred. A safing circuit ( 50 ) is coupled to the sensor ( 24 ) signal and sequestered from the discrimination circuit ( 42 ) for determining if the predetermined event occurred. An actuation device is actuates the restraint when both the discrimination circuit ( 42 ) and the safing circuit ( 50 ) determine the predetermined event occurred.
