Means of locomotion, arrangement and device for evaluating a signal of an airbag control unit
A means of locomotion, an arrangement as well as a device ( 1 ) for evaluating a signal of an airbag control unit ( 2 ) are being put forward. The device ( 1 ) comprises a first connection ( 3 ) for electrically contacting an output of the airbag control unit ( 2 ), a rectifier ( 5 ) that is electrically connected to the first connection ( 3 ), a temperature-compensated driver ( 6 ) that is connected to an output of the rectifier ( 6 ) [sic], and a member ( 7 ) for the galvanic decoupling of an output of the driver ( 6 ), having an output unit ( 8 ). The rectifier ( 6 ) provides polarity reversal protection for the first connection ( 3 ) so that the driver ( 6 ) receives an output signal from the airbag control unit ( 2 ) essentially identically, independently of its polarity.
1. A device for evaluating a signal of an airbag control unit, comprising:
a first connection for electrically contacting an output of the airbag control unit,
a rectifier that is electrically connected to the first connection,
a temperature-compensated driver that is connected to an output of the rectifier, and
a member for a galvanic decoupling of an output of the driver, having an output unit.
2. The device according to claim 1 , whereby the output unit has a crash-out line.
3. The device according to claim 1 , whereby the driver also has a current-limiting function.
4. The device according to claim 1 , whereby the rectifier comprises a bridge rectifier.
5. The device according to claim 1 , whereby the rectifier comprises FET rectifier.
6. The device according to claim 1 , whereby the member for galvanic decoupling has an optocoupler.
7. An arrangement comprising:
an airbag control unit,
a ignition pellet reproduction and a device according to claim 1 ,
whereby the first connection is connected to an airbag control unit.
8. The device according to claim 7 , whereby the airbag control unit is configured to cyclically apply test pulses to the ignition pellet reproduction.
9. An electrically powered means of locomotion having an electric and/or electrochemical source of traction power, comprising:
a device according to claim 1 , and/or
an arrangement comprising:
an airbag control unit,
a ignition pellet reproduction,
whereby the first connection is connected to an airbag control unit.
