A control device and a method for activating passenger protection means for a vehicle are proposed, wherein an interface is provided, the interface serving to receive at least one signal, the amplitude of which depends on the vehicle battery voltage or on an auxiliary voltage taking the place of the latter. Furthermore, an activating circuit is provided, the activating circuit activating the passenger protection means as a function of at least one signal. The interface has a circuit which, in order to detect the at least one signal, derives at least one switching threshold from a supply voltage (auxiliary voltage which is maintained for a certain amount of time in the event of self-sufficiency/undersupply/contact problems) produced in the control device and from a switching threshold which is derived directly from the battery voltage (standard) or from the amplitude of the bus voltage. |
