Synchronization of records of duty status between a vehicle and a stationary unit

A system (10) for synchronizing records of duty status, RODS, information of a vehicle with a stationary unit, comprising:

• at least one mobile unit (100) configured to generate RODS, store the generated RODS, and transmit RODS;
• and
• a stationary unit (300) configured to receive and store RODS transmitted by the at least one mobile unit,
• wherein the at least one mobile unit (100) is further configured to transmit a newly generated first RODS to the stationary unit in an initial synchronization step of a synchronization process of synchronizing the RODS stored on the at least one mobile unit and the RODS stored on the stationary unit,
• wherein the at least one mobile unit (100) is further configured to generate a checksum of the first RODS after transmission of the first RODS to the stationary unit and to transmit only the checksum of the first RODS to the stationary unit in a subsequent synchronization step of the synchronization process, and
• wherein the checksum is generated according to a first checksum generation algorithm.
