A method and a system for updating operating software of subcomponents of a motor vehicle. The updating is not component-specific but vehicle-function-specific.

Method and system for updating operating software of subcomponents of a motor vehicle

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 () is monitored in a central diagnostic control unit (), optionally using a mathematical model. This is advantageous in that each control unit () does not have to be provided with a memory and calculation capacity for the diagnosis.

Device and method for central on-board diagnosis for motor vehicles

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 () is monitored in a central diagnostic control unit () 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.
