EFAS 5 Smart Tachograph

Starting in June 2019, Smart Tachographs are mandatory in commercial vehicles registered for the first time where the maximum permissible mass of the vehicle, including any trailer, or semi-trailer, exceeds 3,5 tonnes.

The Smart Tachograph System consists of the Smart Tachograph Vehicle Unit, the GNSS receiver, the remote communication facility (DSRC Unit) and further equipment like smart cards and motion sensor.

Highlights of EFAS 5

  • By deploying excellent system architecture, EFAS 5 Smart Tachograph Vehicle Unit fits in almost all vehicle types. This eliminates the need for multiple hardware versions (e.g. 12 or 24 V power supply) for different vehicle types
  • EFAS 5 Smart Tachograph Vehicle Unit supports the remote communication facility “E5.DU” DSRC Unit.
  • EFAS 5 provides an internal GNSS antenna to determine the position. Optional: Connection to an external GNSS antenna via FAKRA connector is possible.
  • The easy menu navigation simplifies and speeds up the installation workflow. The easy-to-use software EFAS Service Tool for workshop professionals enables the setting of vehicle parameters in the blink of an eye. Configuration of EFAS Tachographs, software updates, diagnostics and test routines are available in many languages.
  • An Installation Setup Wizard simplifies installation and parametrization by automatic setup of basic parameters like CAN bus data transfer rate. The Setup Wizard minimizes workload and accelerates the installation process
