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.

Abstract: A method of booting up update software in a writable memory area of a boot sector of a programmable control device of a vehicle is provided. The method Provides a boot-up software that can be booted up in a writable memory area of the programmable control device which is situated outside the boot sector. The boot-up software is capable of controlling, in the control device, the installation of the update software in the writable memory area of the boot sector, booting up the boot-up software and the update software in the writable memory area situated outside the boot sector, and executing the boot-up software in the control device in order to install the update software in the writable memory area of the boot sector.
