Abstract
A controller for triggering a pyrotechnic component of a vehicle is designed to determine and store a trigger status of the pyrotechnic component. The trigger status exhibits a triggered state or a non-triggered state. The controller is further designed, if the trigger status exhibits the non-triggered state, to allow operation of the controller with a pyrotechnic component in the vehicle without enabling the pyrotechnic component. Further, the controller is designed, if the trigger status exhibits the triggered state, to reset the trigger status from the triggered state to the non-triggered state when the pyrotechnic component is enabled.
Claims13
An apparatus for triggering a pyrotechnic component of a vehicle, comprising:
- a controller operatively configured to:
- determine and save a trigger status of the pyrotechnic component, wherein the trigger status exhibits a triggered state or a non-triggered state;
- in an event that the trigger status exhibits the non-triggered state, permit operation of the controller with a pyrotechnic component in the vehicle, without enabling the pyrotechnic component;
- and
- in an event that the trigger status exhibits the triggered state, reset the trigger status from the triggered state to the non-triggered state, when an enablement of the pyrotechnic component is in force, wherein the trigger status is associated with whether or not the pyrotechnic component has been deployed, and the enablement of pyrotechnic component makes the pyrotechnic component functional.
A method for protection against unauthorized installation of a pyrotechnic component in a vehicle, the method comprising:
- determining and saving a trigger status of the pyrotechnic component, wherein the trigger status exhibits a triggered state or a non-triggered state;
- in an event that the trigger status exhibits the non-triggered state, permitting the operation of the controller with a pyrotechnic component in the vehicle, without enabling the pyrotechnic component;
- and
- in an event that the trigger status exhibits the triggered state, resetting the trigger status from the triggered state to the non-triggered state, when an enablement of the pyrotechnic component is in force, wherein the trigger status is associated with whether or not the pyrotechnic component has been deployed, and the enablement of pyrotechnic component makes the pyrotechnic component functional.
