Abstract

A method for triggering at least one passenger protection means. The method includes a step of reading in a control signal which contains a command for carrying out an activation of the passenger protection means. Furthermore, method includes a step of releasing an activation of the passenger protection means as a response to the read-in control signal. Furthermore, the method includes a step of evaluating the control signal for the identification of the command for carrying out the activation of the passenger protection means and activating the passenger protection means as a response to an identified command for carrying out the activation of the passenger protection means to trigger the passenger protection means.

Claims

1. A method for triggering at least one passenger protection arrangement, comprising:

reading in a control signal which contains a command for carrying out an activation of the passenger protection arrangement;

releasing an activation of the passenger protection arrangement as a response to the read-in control signal; and

evaluating the control signal for an identification of the command for carrying out the activation of the passenger protection arrangement and activating the passenger protection arrangement as a response to an identified command for carrying out the activation of the passenger protection arrangement to trigger the passenger protection arrangement.

2. The method as recited in claim 1, wherein in the step of reading in, a control signal is read which has an encoded command for carrying out the activation of the passenger protection arrangement, the encoded command being decoded in the step of evaluating the control signal.

3. The method as recited in claim 1, wherein the control signal is read in by a PSI5 reading-in interface in the step of reading in.

4. The method as recited in claim 1, wherein the passenger protection arrangement is triggered by using a non-encoded activating signal in the step of evaluating and activating.

5. The method as recited in claim 1, wherein the identification of the command for carrying out the activation of the passenger protection arrangement takes place in the step of evaluating when two different sequences are recognized in the control signal, each sequence representing a piece of information regarding an activation of the passenger protection arrangement to be carried out.

6. The method as recited in claim 1, wherein the passenger protection arrangement is triggered in the step of activating only if the command is identified in the control signal.

7. The method as recited in claim 1, further comprising:

pre-processing at least one sensor signal of a sensor, the pre-processing including reading in the sensor signal and subsequently outputting the sensor signal as a response to the control signal when the sensor signal meets a predetermined criterion.

8. The method as recited in claim 6, wherein in the step of pre-processing, the control signal is output using a PSI5 transmission interface.

9. A control unit, comprising:

a plurality of devices for triggering at least one passenger protection arrangement, including;

an arrangement for reading in a control signal which contains a command for carrying out an activation of the passenger protection arrangement;

an arrangement for releasing an activation of the passenger protection arrangement as a response to the read-in control signal; and

an arrangement for evaluating the control signal for an identification of the command for carrying out the activation of the passenger protection arrangement and activating the passenger protection arrangement as a response to an identified command for carrying out the activation of the passenger protection arrangement to trigger the passenger protection arrangement.

10. A computer program product having program code that when executed on one of a control unit and a device carries out a method for triggering at least one passenger protection arrangement, comprising:

reading in a control signal which contains a command for carrying out an activation of the passenger protection arrangement;

releasing an activation of the passenger protection arrangement as a response to the read-in control signal; and

evaluating the control signal for an identification of the command for carrying out the activation of the passenger protection arrangement and activating the passenger protection arrangement as a response to an identified command for carrying out the activation of the passenger protection arrangement to trigger the passenger protection arrangement.
