Views Read Edit View history. The disc is preprinted with a speed scale and the stylus produces a mark corresponding with the speed of the vehicle at any given time.


It is important that the maximum speed Vmax specification of the chart matches that of the tachograph dgitaler for the speed to be correctly recorded. The last implementations developed in Mexico have GPS capabilities such as mapping, altitude and location-activated video triggering.

The sender unit and head are electronically paired and the pulses from the sender to the head are encrypted, therefore deterring tampering by intercepting or replicating the pulse signal in the intermediate wiring. Adoption of the legislation: The trace closest to the outer edge is the speed trace. Design specifications prevent data being altered or deleted, therefore ensuring the integrity of the data for subsequent analysis and presentation in a court case.

The rest and availability modes can be manually selected by the driver whilst stationary. There is no facility to prevent it being inserted back to front, where the styli would be prevented from making contact with the wax surface. Later analogue tachograph head models are of a modular design, enabling the head to fit into a standard DIN slot in the vehicle dashboard.


The centrefield is used by the driver to store certain handwritten information. Please help improve this article by adding citations to reliable sources.

Digital tachograph

The stylus moves up and down with distance travelled, producing a zig-zag pattern, often referred to as a ‘V’ trace. This ensures that the data cannot be retrieved digitalrr another company should the vehicle subsequently change ownership, or in the case or lease or hire vehicles that are used by many companies during their life.

Opponents claimed that it was doubtful whether strict enforcement of these regulations would reduce driver fatigue since they were not based on scientific evidence. The driver’s activity is displayed in this area, and is always displayed as either driveother worktachorgaph or rest.

Without a digital card reader, computer and analysis software, the data can be more difficult to interpret as it is not visually represented as the analogue chart is, and requires mathematical calculations to decipher the information from its presented format.

The ‘drive mode’ is activated automatically when the vehicle is in motion, and digital tachograph heads usually default to the ‘other work’ mode upon coming to rest.

Digital tachograph – Wikipedia

Smart tachographs are the new generation of on-board mandatory digital recorders to enforce the EU legislation on professional drivers driving and resting times social regulation. For this reason, the drive mode is no longer available to be selected by the mode switch. They are also used in the maritime world, for example through the Central Commission for Navigation on the Rhine. Unsourced material may be challenged and removed. The trace closest to the centrefield is the tacgograph trace.

The inventor was Max Maria von Webera civil servant, engineer and author. When either memory bank is full, the oldest data is automatically overwritten with the current data.

The analogue tachograph head uses styli to trace lines on a wax coated paper disc that rotates throughout the day, where one rotation encompasses a hour period.
