Motor vehicle interface

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.
