ABSTRACT:
A device is proposed for protecting a motor vehicle against theft. At least one signal processing evaluates a sensor signal of a sensor in a first operating mode for generating an activation signal for a functional unit. A signal unit evaluates the sensor signal in a second operating mode, which differs from the first operating mode, for producing an activation signal for an alarm-signal generator. An operating-state detection is provided for detecting whether the motor vehicle is in a deactivated state. The second operating mode is activated when the motor vehicle is in the deactivated state; the first operating mode is activated when the motor vehicle is in the activated state.
