Abstract
A method for changing over to a firmware version in an electrical control unit for a drive system, wherein the electrical control unit is suitable for executing an existing application program for operating the drive system, and a different firmware version is in operation in the electrical control unit. The method a) checks the existing application program for compatibility with the one firmware version by use of a script, and b) in the case where the existing application program is compatible with the one firmware version, changes over from the other firmware version to the one firmware version in the electrical control unit.
Claims9
A method for changing over to a second firmware version in an electrical control unit for a drive system, wherein the electrical control unit is suitable for executing an existing application program for operating the drive system, and a different, first firmware version is in operation in the electrical control unit, the method comprising the steps of:
- a) checking the existing application program for compatibility with the second firmware version by way of a script;
- and
- b) in a case where the existing application program is compatible with the second firmware version, changing over from the first firmware version to the second firmware version in the electrical control unit, wherein the second firmware version then occupies an intermediate position between hardware of the electrical control unit and the existing application program,
- wherein the method further comprises the steps of:
- changing over to the script, in one script version that has been assigned to the second firmware version, from a different script in a different script version that has been assigned to the first firmware version, and
- wherein step a) carries out the checking by use of the script in the one script version, wherein the script is in a script version corresponding to the second firmware version or higher, and
- wherein the script is designed to read out the application program itself, at least partially, and on the basis thereof to check the compatibility.
An apparatus, comprising:
- an electrical control unit for a drive system, the electrical control unit being configured to execute an existing application program for operating the drive system, wherein a different first firmware version is in operation in the electrical control unit, wherein
- the electrical control unit is operatively configured to execute a changing over to a second firmware version by:
- a) checking the existing application program for compatibility with the second firmware version by way of a script;
- and
- b) in a case where the existing application program is compatible with the second firmware version, changing over from the different first firmware version to the second firmware version in the electrical control unit, wherein the second firmware version then occupies an intermediate position between hardware of the electrical control unit and the existing application program,
- wherein the electrical control unit is further operatively configured to:
- change over to the script, in one script version that has been assigned to the second firmware version, from a different script in a different script version that has been assigned to the first firmware version, and
- wherein the checking is carried out by use of the script in the one script version, wherein the script is in a script version corresponding to the second firmware version or higher, and
- wherein the script is designed to read out the application program itself, at least partially, and on the basis thereof to check the compatibility.
A drive system, comprising:
- an electrical control unit for a drive system, the electrical control unit being configured to execute an existing application program for operating the drive system, wherein a different first firmware version is in operation in the electrical control unit;
- and
- an electric motor actuator, the electrical control unit being assigned to the actuator for control purposes, wherein
- the electrical control unit is operatively configured to execute a changing over to a second firmware version by:
- a) checking the existing application program for compatibility with the second firmware version by way of a script;
- and
- b) in a case where the existing application program is compatible with the second firmware version, changing over from the first firmware version to the second firmware version in the electrical control unit, wherein the second firmware version then occupies an intermediate position between hardware of the electrical control unit and the existing application program,
- wherein the electrical control unit is further operatively configured to:
- change over to the script, in one script version that has been assigned to the second firmware version, from a different script in a different script version that has been assigned to the first firmware version, and
- wherein the checking is carried out by use of the script in the one script version, wherein the script is in a script version corresponding to the second firmware version or higher, and
- wherein the script is designed to read out the application program itself, at least partially, and on the basis thereof to check the compatibility.
