Problems solved by technology

This can lead, for example, to corrupted, corrupted or outdated vehicle-to-external (V2X) information transmitted by a vehicle-to-external (V2X) communication device via a data bus to other vehicle systems
thereby, in particular, negatively impacting the operational safety of a vehicle or leading to a serious safety-impacting situation, or failing to take appropriate measures to address a potential serious safety-impacting situation

Embodiment Construction

[0063] figure 1 According to the present invention, an exemplary embodiment of a method for ensuring the integrity of data transmitted to a vehicle control module through a vehicle-to-external information exchange (V2X) communication device of a vehicle to ensure operational safety (Safety) is presented. In a step 1.1, the data transmitted by vehicle-to-external information exchange communication is received by a first computing device of the vehicle-to-external information exchange (V2X) communication device, and stored in a data memory in a step 1.2. In a step 1.3, the first computing device forwards the data to a second computing device that receives the data. In a step 1.4, the second computing device detects whether an actuator action should be triggered according to the received data, and responds to triggering an actuator action, and sends the data to a comparing device in the first computing device. In a step 1.5, the comparing means in the first computing means compa...

Abstract

A method for ensuring integrity of data sent by a vehicle V2X communication device to a control module to ensure operational safety, including: receiving data transferred by vehicle-to-X communicationby a first computing apparatus of the V2X communication device, storing the data in a data memory, forwarding the data to a second computing apparatus, receiving the data by the second computing apparatus, establishing whether an action is to be triggered for the data and, in response, transmitting the data to a comparison apparatus, carrying out a comparison test for the data provided by the second computing apparatus with the data stored in the data memory and, in response to the test being passed, outputting the data and / or a control instruction and / or a warning message by the V2X communication device to a control module. Furthermore, a corresponding vehicle-to-X device and the use of the device in a vehicle are disclosed.

Description

technical field [0001] The present invention relates to a method for ensuring the integrity of data transmitted to a vehicle control module through a vehicle-to-external information exchange (V2X) communication device of a vehicle to ensure operational safety, a corresponding vehicle-to-external information exchange (V2X ) communication devices and their uses. Background technique [0002] Vehicle-to-external information interaction (V2X) communication is the status quo of scientific research or pre-development, and is currently in the process of standardization. Relevant standards are IEEE802.11(p), IEEE1609, SAE 2735, SAE 2945 and ETSI ITS-G5. Furthermore, new standards are currently being developed in 3GPP for C-V2X or LTE-V2X or 5G V2X. Functional safety is described in the ISO 26262 standard for the automotive industry. [0003] In particular, an internal error in a vehicle-to-external (V2X) communication device used for vehicle-to-external information exchange (V2X)...
