CAN bus interfaces

How do I get a speed pulse from a CAN bus vehicle?

A CAN bus speed pulse interface reads road speed from the vehicle data bus and provides a signal for equipment that expects it, such as a tachograph, taxi meter, speed limiter or tracker.

If you need a speed signal on a modern vehicle, the old approach of splicing a mechanical or hall-effect sender often no longer applies. Road speed lives on the vehicle CAN bus instead. A CAN interface reads that data so you can drive equipment that still expects a road speed input.

What the interface actually does

The unit connects to the vehicle CAN bus and reads the road speed the vehicle is already broadcasting. From there it can provide a signal to the device you are fitting. What that output looks like depends entirely on what you are feeding, so we do not treat it as one fixed thing. Tell us the vehicle and the device you are feeding, whether that is a tachograph, taxi meter, limiter or tracker, and we confirm the output it needs and configure the unit for it.

Two units for the common jobs

The CAN KONTROL SPEED is aimed at applications that need road speed alone. Where you also need engine speed, the CAN KONTROL SPEED RPM reads both from the bus so a single module covers a speed and RPM requirement.

Both are built on the i2CAN platform, designed and manufactured in the UK by Intellitec, part of Scorpion Group. One configurable platform covers the range, so the same hardware is set up to the vehicle and the job rather than swapped for a different box each time.

What to tell us

Give us the make, model and year, and the exact device you are feeding along with the input it expects. If the signal you need is not on the standard list, we can look at developing it. Tell us the vehicle and the device, and we configure the output it needs.

Frequently asked questions

Can a CAN bus interface give me a speed pulse?
It reads road speed from the vehicle bus. What that becomes at the output depends on the device you are feeding, so tell us the vehicle and the equipment and we confirm the output it needs and configure the unit for it.
What equipment can it feed?
Typical uses are tachographs, taxi meters, speed limiters, trackers and other telematics that expect a road speed input. Every application is confirmed on enquiry against the vehicle and the target device.
Do I have to cut into the wiring?
On most vehicles the unit reads the bus through a two-wire connection. On vehicles under warranty it can read the bus with a no-cut inductive reader, leaving the native loom intact.
What if my vehicle or device is not on your list?
Tell us the vehicle and the signal you need. Because we design and build the platform in-house, if it needs a signal that is not on the standard list we can look at developing it.
