TomTom devices gives access to engine info for smartphone use

TomTom Business Solutions is launching a new device the TomTom Link 100. This connects to the engine management unit (EMU) via the standard CAN-bus and has a built in 3D accelerometer. This then can connect to a smartphone device via Bluetooth allowing easy diagnostics in the event of a crash or even the vehicle breaking down.

All modern cars use the standard bus interface so it should work will most cars on the road.

The device can also be used by insurance companies to track driving habits etc (though no GPS information is available), drivers could also use the device to improve their driving.

TomTom have not said what data is exposed (apart from RPM, load and temperature), though the EMU provide a lot more information and with the right application many minor faults can be reset by such a device making trips to the garage less frequent (and also allowing drivers to check what faults garages etc are charging them for and whether it is a major or minor fault).

If the all the data is exposed and TomTom allow read and write information it could allow app vendors to make interesting solutions to make the driving experience better, though of course insurance companies will want these devices to ensure drivers drive better.
