Abstract: A device and method for filtering safety-relevant interventions, having a control unit as well as a first communications unit, which is able to exchange data with at least one bus system of a vehicle, and having a second communications unit, which is able to exchange data with an external processing unit. A third communications unit is provided, which differs from the first communications unit and the second communications unit, and the control unit filters the data transfer between the first communications unit and the second communications unit as a function of a parameter received by the third communications unit.

Abstract: A method for evaluating signal data includes a bus signal channel supplying the signal data, a reference channel supplying reference signal values, which form the basis of the signal data, and a computer performing a signal interpretation based on an interpretable portion of the signal data and on the reference signal values, and reconstructing a signal based on the interpretation.

Abstract: An interface for providing a secure interface to a motor vehicle, in particular, for communication with control electronics of the motor vehicle, includes: a first interface having multiple terminals, which is configured for communication with control electronics of the motor vehicle; a second interface, which is for communication with an external diagnostic device; a first processing unit, which is to transmit data between the first and the second interface; a second processing unit, which is to monitor the data transmission between the first interface and the second interface, to recognize an unsafe state and to interrupt the data transmission if an unsafe state has been recognized; and a circuit, which enables terminals of the first interface to be selectively connected to inputs and/or outputs of the first processing unit and/or the second processing unit.
