US 2024/0195824 A1 · Method for Identifying a Manipulation of a Message of a Bus System by Means of a Control Device of a Vehicle, Computer-Readable Medium, System, and Vehicle

Abstract

A method identifies a manipulation of a message of a bus system using a control device of a vehicle. Th method includes receiving a first message from a first control device using the control device of the vehicle. The method also includes receiving a second message from a second control device using the control device of the vehicle, and determining a system status of the vehicle based at least in part on the second message from the second control device. The method further checking a plausibility of a content of the first message using the determined system status of the vehicle using the control device of the vehicle in order to identify the manipulation of the first message. An alarm message is provided if the content of the first message is not plausible.
