Abstract: A software update monitor is configured to receive a software update intended for a safety critical control unit. The software update monitor determines a first verification code based on the received software update from a software update component and independently receives a second verification code associated with the software update from an update server. Next, it determines if the first verification code matches the second verification code. If the two codes match, the software update monitor effects the software update at the control unit. The software update monitor is configured to write the software update into a target memory location in a memory of the control unit. The software update monitor is configured to enable switching from a previous memory location, where an older software version may be running, to the target memory location, where the new software update is written, if the first and the second verification codes match.
