Chronotachygraphe

See also: Informer

The chronotachygraphe is a recording electronic device of Speed, time of control and activities (work, waitings…) installed in a Vehicle of road transport.

In its digital version using of the discs papers, the instantaneous speed of the vehicle is recorded compared to the current hour. By an easy reading, it allows the drivers and the owners to know followed speed, the downtimes (lawful cuts), times of control like all the availability or working times, whose total will give the time of service. It makes it possible to take care of the respect daily and weekly rest periods prescribed by the legislative texts like the respect of times of maximum control.

History

The first tachographs were railway before even 1900. Such as for example the Flaman, they highlighted the regularity of control and the respect of indication more than time of control.

The chronotachygraphe (called " commonly; mouchard") applied to the Camion S exists since the beginning of the years 1920. The recording was generally done on discs of Papier. A disc is attached to each driver and not with the vehicle because it is the personal time of control over the week which can be controlled. It is obligatory on all the vehicles of goods transport (of more than 3,5 T) and travellers since 1969.

Numerical Chronotachygraphe

Since the 5/1/2006 the installation is obligatory on the new vehicles like to replace a broken down analogical chronotachygraphe by a UEV (Embarked Unit of the Vehicle) numerical on the freight vehicles of people of more than 9 places and on the vehicles of goods transport of more than 12 tons and whose date of the 1st putting into circulation is after the 1/1/2003. Vehicles equipped ADR (goods transport dangerous) are not concerned with this modification of technology.

By imposing this system and a European regulation, the European Union wants to improve and facilitate the control of times of control and rest, and to fight thus one of the major causes of the road accidents on the level of the heavy trucks.

The system is based on a recording device sealed and installed by an approved and sworn in personnel. It must comprise a permanent and inviolable storage system as well as a printer. The transfers of information are done by chip cards interopérables between manufacturers of system and country. There exist four types of charts:

  • the chart conducting , white, strictly personal, records and memorizes the relative data at 28 days of activity, whatever the driven vehicle. The information stored on the chart relates to the identification of the driver, of the driven vehicles, times of control, work, of rest, the statute of control, the distance covered, the faulty operations, the breakdowns. This chart has 5 years a maximum administrative validity.
  • the chart undertaken , yellow, is used by the owner to allow the remote loading of the contained informations in the Embarked Unit of the Vehicle.
  • the chart control , blue, fulfills the same function for the controlling authorities, knowing that these last also have a specific computer material to recover the whole of the data.
  • the chart workshop , red, is used to gauge and repair the chronotachygraphe in approved centers which have the suitable material for the calibration of the apparatus.

Manufacturers

Three manufacturers currently dispute the European market of the numerical chronotachygraphes with chip cards: Actia, Siemens and Stoneridge Electronics.
