Updating and/or expanding the functionality of sequence control of at least one control unit
First Claim
1. A method for upgrading or expanding functionality of a sequence control of at least one control unit of a motor vehicle, comprising the acts of:
- reading a first data from a first control unit, and determining a version of the sequence control currently running in the first control unit based upon the first data, reading a second data from a second control unit, and determining a version of the sequence control currently running in the second control unit based upon the second data, determining, in a first check, whether the version of the sequence control currently running in the second control unit corresponds to a predetermined version of the sequence control or is more current than the predetermined version, and if the result of the first check is positive, saving a more current version of the sequence control with respect to the version currently running in the first control unit or a version which expands the functionality, or saving another sequence control or saving additional data versions in the first control unit.

Abstract
A method, system, and computer program product for updating and/or expanding the functionality of the sequence control of at least one control unit of a motor vehicle are provided. In accordance with the method, a first data may be read from a first control unit and a second data may be read from a second control unit. A first check in the vehicle may be performed to ascertain whether the version of the sequence control currently running in the second control unit corresponds to a predetermined version of a sequence control or is even more current than the predetermined version. If the outcome of the first check is positive, a more current version in comparison with the version of the sequence control currently running in the first control unit may be saved and/or a version which expands the functionality may be saved in the first control unit.

17. A system for updating or expanding functionality of sequence control of at least one control unit of a motor vehicle, the system comprising:
-
a first control unit configured to operate with a first sequence control version, and a second control unit configured to operate with a second sequence control version, wherein a first check determines whether the version of the sequence control currently running in the second control unit corresponds to a predetermined version of the sequence control or is more current than the predetermined version, and if the result of the first check is positive, a more current version of the sequence control with respect to the version currently running in the first control unit or a version which expands the functionality is saved, or another sequence control or additional data versions are saved, in the first control unit.

18. A computer program product for updating or expanding functionality of a sequence control of at least one control unit of a motor vehicle, the computer program product stored on a computer readable medium and adapted to perform operations comprising:
-
reading a first data from a first control unit, and determining a version of the sequence control currently running in the first control unit based upon the first data, reading a second data from a second control unit, and determining a version of the sequence control currently running in the second control unit based upon the second data, determining, in a first check, whether the version of the sequence control currently running in the second control unit corresponds to a predetermined version of the sequence control or is more current than the predetermined version, and if the result of the first check is positive, saving a more current version of the sequence control with respect to the version currently running in the first control unit or a version which expands the functionality, or saving another sequence control or saving additional data versions in the first control unit. - View Dependent Claims (19, 20)
