Abstract
In a method for entering program data into a control unit in a motor vehicle, the program data are provided by a data transfer point, via the following steps: a program data acceptance request is sent to the control unit, the control unit changes to a program data acceptance state, the program data are transmitted to the control unit, and the program data are accepted by the control unit. Before the control unit changes to the program data acceptance state, the control unit checks whether program data acceptance conditions prescribed for the control unit exist.
Claims13
A method for entering program data into a control unit in a motor vehicle from a data transfer point, said method comprising:
- sending a program data acceptance request to the control unit;
- transmitting the program data to the control unit;
- and
- the control unit checking whether program-data-independent program data acceptance conditions prescribed for the control unit are satisfied;
- and
- the control unit changing to a program data acceptance state in which the program data are accepted by the control unit after the control unit has determined that the program data acceptance conditions are satisfied.
A control unit for a component in a motor vehicle, comprising:
- means for accepting program data from a data transfer point;
- and
- means for checking whether prescribed program data acceptance conditions in the control unit are satisfied, as a requirement for accepting program data.
A data transfer system for transmitting program data to a control unit in a motor vehicle, comprising:
- a data transfer point;
- a control unit having means for accepting program data from the data transfer point;
- and
- means for checking whether prescribed program data acceptance conditions are satisfied in the control unit and in the data transfer point;
- wherein the means for checking prescribed program data acceptance conditions in the control unit are adapted to request the check results for the check on prescribed program data acceptance conditions in the data transfer point.
