Digital Tachograph

According to the regulations, all commercial vehicles must be fitted with a digital tachograph to replace the analogue tachograph. By fitting a digital tachograph to a vehicle, speed, distance and activity can be recorded to make sure drivers and employers follow the rules on driving hours.

The Digital Tachograph System

To understand how to operate your digital tachograph, it’s best to familiarise yourself with how the system works. The system includes a digital driver card, the tachograph head and a sender unit attached to your vehicle’s gearbox. Speed data recording – As the gearbox output shaft turns, the sender unit produces electric pulses, which the head interprets digitally as speed data.

Driver activity recording – The tachograph will digitally record driver activity through a selection of modes. ‘Drive mode’ is activated automatically when your vehicle starts moving and changes to ‘other work’ mode when your vehicle comes to rest. If you do take a rest, you can manually select ‘rest’ or ‘availability’ modes whilst stationary.

Advantages of digital tachograph software

  • The data stored in digital tachographs can be analysed by computers and infringements are identified automatically
  • The design of the software means data can’t be altered or deleted once stored in the head or card
  • The data is easier to interpret than analogue tachographs, without human error
  • When the memory bank in the card or head is full, old data will be overwritten automatically

Digital tachograph software gives fleet managers full visibility of driver hours, rest periods and driving habits, helping you keep your fleet safer and compliant.
