Abstract

To implement an update of the software of a computer device, especially a closed-loop and/or open-loop control device, situated in a means of transportation, such as a motor vehicle, it is proposed to store, prior to starting the update, an image of the software located on the computer device in a data memory which is able to be connected to the computer device via a communications system, to load an updated software onto the computer device, to check whether the update has been successful, and if this is not the case, to transmit at least a portion of the image stored in the data memory to the computer device and to restore it there.

Claims

1. A method for updating software of a control device situated in a motor vehicle, comprising:

storing, prior to starting the update, an image of the software on the control device in a data memory which is able to be connected to the control device via a communications system;

loading an updated software onto the control device;

checking whether the update has been successful; and

transmitting at least a portion of the image stored in the data memory to the control device and restoring the image if the update is not successful.

2. The method as recited in claim 1, wherein the software includes data that are at least one of created and collected, while the computer device is in operation.

3. The method as recited in claim 1, wherein if the update was not successful, at least one further attempt is made to load the updated software onto the computer device.

4. The method as recited in claim 1, wherein the image of the software on the control device is transmitted via a wireless connection to a data memory situated outside the motor vehicle.

5. The method as recited in claim 4, wherein the image of the data memory situated outside the motor-vehicle is transmitted to the control device if the software update was not successful.

6. The method as recited in claims 5, wherein a history of implemented updates together with images transmitted prior to the individual update is stored in the data memory situated outside the motor vehicle.

7. The method as recited in claim 1, wherein a plurality of control devices that are able to be connected to the data memory via at least one communication system is situated inside the motor vehicle, and an update of the control devices is performed.

8. A device for updating software on at least one computer device in a transportation device, the device comprising:

a data memory which is connectable to the computer device via a communications system;

an element to create an image of a software stored on the at least one computer device;

an element to transmit the image to the data memory;

an element to load an updated software onto the at least one computer device;

a test element to check whether the update has been successful; and

a transmission element to transmit the image stored in the data memory to the at least one computer device and to restore the image if the software update was not successful.

9. A control device in a motor vehicle, the control device configured to:

store, prior to starting the update, an image of the software on the control device in a data memory which is able to be connected to the control device via a communications system;

load an updated software onto the control device;

check whether the update has been successful; and

transmit at least a portion of the image stored in the data memory to the control device and restored the image if the update is not successful.

10. A computer readable storage medium storing a computer program, the program when executed by a computer device, causing the computer device to perform a method for updating software of a control device situated in a motor vehicle, the method comprising:

storing, prior to starting the update, an image of the software on the control device in a data memory which is able to be connected to the control device via a communications system;

loading an updated software onto the control device;

checking whether the update has been successful; and

transmitting at least a portion of the image stored in the data memory to the control device and restored the image if the update is not successful.
