Abstract
A device for controlling all airbags for a vehicle is provided, and also a control unit for forming a control signal for all airbags for a vehicle, as well as a system of this device and this control unit. The device has a trigger circuit control and also an energy reserve, in order to control power switches in a trigger circuit as a function of the control signal that comes from the control unit, and to use the energy from the energy reserve to trigger the trigger elements for the airbags. The control unit receives at least parts of the energy supply from the device.
Claims15
A device for controlling airbags of a vehicle, the device having a single housing, comprising:
- at least one energy reserve that receives electric energy from a battery and provides electric energy for an autarchy case,
- a trigger circuit control that has a plurality of power switches, the trigger circuit control controlling the power switches as a function of a control signal to trigger the airbags,
- a first interface that provides the control signal, and
- a supply module, connected between the energy reserve and the trigger circuit control, which provides a boosted battery voltage to charge the energy reserve and a triggering energy for the trigger circuit control to trigger the airbags.
