We have a vast experience in automotive applications and know-how in the interpretation of vehicle signals. Our portfolio is used in the automotive, telematics, industrial and off-road industries.

What can we do for you? We supply you with easy to use electronic equipment to make full use of CANbus, vehicle data and diagnostic signals. We can advise you how to interpret data, build measurement systems and integrate the system into your application.

Squarell is based in the Netherlands (Europe), near the Amsterdam Schiphol Airport. Our customer base spans all continents.

What is a tachograph?

A (digital) tachograph is a device fitted to a vehicle that automatically records its speed and distance, together with the driver’s activity selected from a choice of modes: the drive mode is activated automatically when the vehicle is in motion and modern tachograph heads usually default to the other work mode upon coming to rest. The rest and availability modes can be manually selected by the driver whilst stationary.

Tachograph data via K-line

All digital tachographs have a K-line connection on pin 8 of the D-sub connector (D8 pin). The current tachograph data is transmitted via this connection and describes the current state of the tachograph, driver and the vehicle itself. This data is also transmitted when the vehicle is switched off, making it possible to detect tachograph activities if the driver changes his status when the vehicle is powered down. The Squarell Flex and SOLID-K include a K-Line connector that can be used to connect to the D8 pin of all VDO, Stoneridge and Actia digital tachographs to read the current tachograph data.

The parameters supported by K-line are:• Work State of Driver 1 and 2• Driver ID or Driver 1 and 2• Driving Time Exceeded Warnings Driver 1 and 2• Card Present• Date and Time• Tachograph Vehicle Speed• Odometer• VIN• Vehicle Registration Number

Tachograph download

How does it workThe digital tachograph stores continuous data in the internal memory and driver’s passport. The internal memory stores data from the last 365 days of the vehicle. Data stored on the driver’s pass must be downloaded every 21 days and data contained in the internal memory must be downloaded every 3 months. This data must be stored (in DDD files) so that the government can inspect it. Obtaining the data can be done by going with a dongle or laptop to the vehicle and downloading the data (so the vehicle must be visited). However, it is also possible to read the data remotely via the CANbus using Remote Tacho Download (RTD).

Squarell implementationWith any Squarell interface loaded with the RTD (remote tacho download) profile, it is possible to perform the required downloads via the Remote Tacho Download without actually having to go to the vehicle. With this implementation, the transport company can put the company card in a card reader at the back office. The card reader is connected to the tachograph via the telematic service provider’s modem together with the Flex or SOLID. Now, the (inserted) driver card and the vehicle data in the internal memory can be read. All data of the tachograph can be merged into DDD files to be saved and stored.

Tacho Remaining Driving Time

Tacho Remaining Driving Time is supported in Siemens/Continental VDO digital tachographs since version 2.0a VDO Counter, it might be needed to be activated in version 2.1.

With VDO Counter, all drivers are able to plan their driving and rest times more efficiently. With one glance at the VDO display, you know immediately the remaining driving time and the duration of the next rest period. You can easily see the maximum driving time after each rest period and also the remaining driving time for that day or the week.

Squarell implementationSquarell can extract the VDO Counter parameters from the digital tachograph. The extraction can be done on the remote download CANbus from the tachograph located on the back of the tachograph.

Customers that already have tacho download, can easily upgrade to this new functionality. Customers that do not have tacho download, first need to connect the tacho download CANbus from the Flex/SOLID to the digital tachograph. To activate the Tacho Remaining Driving Time in any Squarell interface, a special profile is needed. The profile can be activated after purchasing and it has ‘RDT’ in its name.

The parameters supported by the new RDT functionality are:• Total Time Of The Current Work State • Total Drive Time Of The Current + The Previous Week • Remaining Drive Time Of The Current/Next Period • Remaining Time Before The Next Break • Time The Next Break Should Be • Remaining Time Of The Current Break • Remaining Time Before The Next Drive Period • Duration Next Drive Period • Remaining Daily Drive Time • Remaining Time Before The Next Daily Break • Time The Next Daily Break Should Be • Remaining Drive Time Of This Week • Remaining Time Before the Next Weekly Break • Time The Next Weekly Break Should Be • Compensation Time Of The Previous Week • Compensation Time Of The 2nd Previous Week • Compensation Time Of The 3rd Previous Week• Remaining Daily Extended Drive Time Periods• Remaining Daily shortened Rest time Periods

The remaining driving time is shown on the truck’s dashboard

At the same time, the remaining driving time is shown on the manager’scomputer at the back office

Why do I need Tacho Remaining Driving Time?The remaining driving time can be manually calculated bymonitoring the real-time data coming out of the tachograph.Research has proven that even the best routines calculatingthese times are a few minutes off in the best scenarios. Butwhen the monitoring device is disconnected, powered downor when the driver manually adds an entry when he entershis Driver Card, great differences can occur between thecalculated values and the real values that are shown on the screen of the tachograph.

Uncalculated data is never wrongThe Squarell Tacho Driving Times are never wrong becausethey come directly from the tachograph. It is plug and playbecause the data can be immediately retrieved from thetachograph and does not have to be calculated (when it iscalculated, the two-week history is unknown and therefore,calculated data needs a startup time of two weeks). Anotheradvantage is, there is no incorrect data when the Squarell interface gets disconnected or when the driver manually adds an entry. And finally, the data Squarell presents is the same as the data displayed on the tachograph and the data the driver is seeing.
