Method and control unit for recognizing manipulations on a vehicle network
First Claim
1. A method for detecting manipulation of at least one vehicle network of a vehicle, the method comprising the following steps:
- ascertaining a digital fingerprint of the at least one vehicle network, wherein the at least one vehicle network is selected from the group consisting of a drive network, a brake network, a train protection network, an air-conditioning control network, a door control network, a passenger information network, and a video monitoring network;
comparing the digital fingerprint of the at least one vehicle network with reference information to determine a manipulation; and
activating a regular control mode if no manipulation of the at least one vehicle network is detected, or activating a safe control mode if a manipulation of the at least one vehicle network is detected.

Abstract
A method for detecting manipulation of at least one vehicle network of a vehicle includes determining a digital fingerprint of the at least one vehicle network, comparing the digital fingerprint of the at least one vehicle network to reference information, adapting a function of the at least one vehicle network as a function of a result of the comparison, such that operational safety is ensured, and activating a regular control mode if no manipulation of the at least one vehicle network is detected, or activating an operationally safe control mode if manipulation of the at least one vehicle network is detected. A control unit for detecting manipulation of at least one vehicle network of a vehicle carries out control tasks as a function of a result of a comparison of a digital fingerprint of at least one vehicle network to reference information of a control network.

19. A network, comprising:
-
a plurality of networks disposed on a vehicle, said plurality of networks including a control network with a control unit and at least one vehicle network selected from the group consisting of;
a drive network, a brake network, a train protection network, an air-conditioning control network, a door control network, a passenger information network, and a video monitoring network;said control unit configured to compare a digital fingerprint from said at least one vehicle network with reference information from said control network to determine a manipulation, wherein said control unit is a computer; and said control unit configured for activating a regular control mode if no manipulation of the at least one vehicle network is detected, and for activating a safe control mode if a manipulation of the at least one vehicle network is detected. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 28)
