  • the electric drive aid 100 is preferably also in normal operation, if in particular there is neither a warning 350 an alarm 360 is still pending, the continuous transmission of the preferably anonymized relevant operating data 156 to the cloud 400 is provided.
  • the mobile radio connection 404 is preferably implemented by means of a conventional mobile radio standard such as GPRS, Edge, UMTS, HSPA, HSPA +, LTE or LTE-A, etc. Further, a line transmission of the relevant Be operating data 156 from the mobile terminal 200 into the cloud 400 via USB, thunderbolt ®, ® Lightning, LAN etc. be possible.

  • the non-volatile memory device 152 allows the operating data 156 to be read out with a time delay and evaluated in the cloud 400, so that operating data 156 occurring in a stable cellular connection 404 between the mobile terminal 200 and the cloud 400 can be fully taken into account.
  • the Be is also operating software 162 of the data processing unit 150 is preferably wirelessly via the Bluetooth ® Low Energy interface 160 of the radio module updatable or updateable.
