  • Device and method for central on-board diagnosis for motor vehicles
    Patent number: 7539564
    Abstract: The aim of the invention is to improve the diagnosis of motor vehicle systems comprising a plurality of functional components in a network. To this end, the individual status data of the control units (11, 12, 13, 14) is monitored in a central diagnostic control unit (15), optionally using a mathematical model. This is advantageous in that each control unit (11, 12, 13, 14) does not have to be provided with a memory and calculation capacity for the diagnosis.
    Type: Grant
    Filed: January 14, 2004
    Date of Patent: May 26, 2009
    Assignee: Audi AG
    Inventors: Ulrich Siebel, Frank Henecker, Andreas Breuer
  • Device and method for on-board diagnosis based on a model
    Patent number: 7295903
    Abstract: The aim of the invention is to improve the diagnosis of motor vehicle systems comprising a plurality of functional components in a network. To this end, the individual status data of the control units (11, 12, 13, 14) is monitored in a central diagnostic control unit (15) using a mathematical model. Each control unit can also be provided with a self-diagnosis optionally based on a model. By calculating error or causes of error using a model, the control units do not need to be provided with large databases for the diagnosis of error.
