    摘要: A non-inverting dual voltage regulation set point power supply for a restraint control module is disclosed that includes a main power source. A regulated voltage generation circuit connected with said main power source for generating a regulated output voltage having an upper set point and a lower set point. A buck switch connected to said main power source and said regulated voltage generation circuit for bucking the regulated output voltage generated by said regulated voltage generation circuit to said upper set point if said voltage supplied from said main power source is greater than said upper set point. A boost switch connected with said regulated voltage generation circuit for boosting the regulated output voltage generated by said regulated voltage generation circuit to said lower set point if said voltage supplied from said main power source is less than said lower set point.

    摘要: A backup power supply for a restraint control module is disclosed that includes a main power source that is connected to a backup power source charging circuit. A boost converter control and driver circuit is connected with the main power source and the backup power source such that the boost converter control and driver circuit controls the charging of the backup power source with the main power source during normal operation. A backup power supply control and driver circuit is connected with a backup power supply switching device. The backup power supply control and driver circuit switches the source of power from the main power source to the backup power source when the backup power supply control circuit senses a loss of power from the main power source.

    摘要: A circuit 17 for interfacing with a sensor 18 having a sensor input current and a modulated sensor current signal corresponding to a sensed condition. A control module 20 is coupled to the sensor 18 and receives the sensor current signal. The control module 20 converts the sensor current signal to a modulated signal having a pulse width with a duration corresponding to the sensed condition. The control module 20 counts a time corresponding to the pulse width. The time corresponds to the sensed condition.

    摘要: A sensor system for detecting impacts to a vehicle, including diagnostics for monitoring the sensor system. The sensor system includes one or more piezoelectric sensor assemblies (42), each including a coaxial piezoelectric cable (44) contained within a tube housing (54), which is mounted to a structural member of the vehicle. The sensor system may also include accelerometers (36, 38) that are also in communication with the restraints control module (40) and employed in combination with one or more piezoelectric sensor assemblies (42). Further, the sensor system includes diagnostics for monitoring one or more of the sensor assemblies (42) in order to detect a sensor failure, while not interfering with the impact signals from the sensor assemblies (42).
