METHOD AND DEVICE FOR CONTROLLING DATA TRANSMISSION BETWEEN TWO MODULES LOCATED IN A MOTOR VEHICLE

摘要

The invention relates to a method and device for controlling the data transmission between two modules located in a motor vehicle which are connected to each other via a communication interface and a communication bus. The transmitting module defines the data, to be transmitted in the form of code words, in accordance with sensor signals generated by a first sensor and a second, redundant sensor. The sensor signal of one of the two sensors is applied directly to the communication interface of the module and is used to verify and/or modify part of the code word applied to said communication interface for the purpose of transmission.
