摘要： A control arrangement for a deployable airbag of a vehicle is provided with first (31) and second (32) airbag controllers for receiving a fault signal at the first airbag controller (31), and for producing at the second airbag controller (32) a deployment command signal to deploy the airbag. The second airbag controller is provided with a communication controller (51) for receiving the deployment command signal and a squib fuse (57) is fired. An energy transfer arrangement is coupled (52) to the communication controller and the squib fuse to transfer energy to the squib fuse in response to the deployment command signal. The squib fuse requires a predeterminable minimum quantum of energy to effect the firing thereof. A heater (56) provides a radiated preheat to the squib fuse whereby the quantum of energy applied to fire the squib fuse is exceeded. The radiated preheat energy is monitored (58) and controlled.

摘要： A vehicle weight classification system (20) recognizes the various factors that influence system performance. Some of the factors are compensated for using analog signal processing circuitry or techniques. Other factors are compensated for using digital signal processing techniques. The unique combination of analog and digital approaches, rather than pure analog or pure digital, provides an effective solution at addressing the various factors that influence signals and system performance in a vehicle weight classification system while keeping the cost and complexity of the system within acceptable limits.
