Abstract:
1. A method for monitoring a bus system having at least three users in a vehicle having a drive unit and a lockable vehicle area, comprising: forming precisely one first user of the at least three users as a superordinate user; initiating each data transmission on the bus system; forming at least one second user as an element of a locking system in the vehicle; and arranging at least one third user outside of the lockable vehicle area, wherein: the first user monitors the data transmission such that the first user, for each data transmission on the bus system that was not initiated thereby, introduces a measure to prevent transmission of the data; the data transmission is prevented in that the data to be transmitted are at least partially destroyed by the superordinate user; and the data to be transmitted are destroyed by the superordinate user in that the bus system is tied to ground potential and the data transmission is thus blocked; wherein after a wait time, the superordinate user cancels a blocking of the data transmission and again monitors whether the data transmission is taking place that was not initiated thereby, and the data transmission then is blocked once more, otherwise the blocking being canceled.
