Abstract

The present invention relates to a method and an apparatus for controlling the data transmission between two modules which are present in a motor vehicle and are connected to one another via a communications interface and a communications bus. The transmitting module defines the data to be transmitted in the form of code words in dependence on sensor signals generated by a first sensor and a second, redundant sensor, the sensor signal of one of the two sensors being applied directly to the communications interface of the module and serving for checking and/or changing part of the code word applied to the communications interface for the purpose of transmission.
