GPS Based signal generator for tachographs

Would you like to avoid annoying questions? Stay legal with us!

According to the new regulations tachographs requires a secondary signal source generator independent from the wheel speed sensor.

TachoPulse is a speed-based signal-generating device designed for vehicles with tachographs. It provides a secondary source of motion for tachographs, required as of October 1st, 2012 by European Commission regulation no. 1266/2009. The device generates frequency impulses and CAN messages proportional with the speed of the vehicle using GPS. Due its double constellation receiver GPS and GLONASS, it is capable of producing quality signals even in heavily populated urban areas.
With two standard outputs, TachoPulse is easy to install and compatible with most tachographs on the market:

  • Frequency with voltage swing between the battery rails
  • CAN output according to the SAEJ1939 SPN904 Front axle speed message
