AB Dynamics developed path-following in 2000 initially for vehicle dynamics testing. Since then, they have worked with customers to develop and enhance this technology, and today it forms the basis for how many different types of tests are performed.

Path-following even works on snow and low-friction surfaces
Working with our clients at winter proving grounds, AB Dynamics has shown that its path-following system works reliably and accurately even on low friction surfaces like snow. The algorithm recognises vehicle oversteer and understeer, automatically applying corrective steering to stay on the path.
Our customers use path-following to evaluate vehicle behaviour and stability control systems on frozen surfaces, as well as for testing winter tyres on a range of surfaces.
Indoor path-following
Path-following can now be done indoors with no GPS signal, proven in this video showing a demonstration of indoor path-following at IIHS Vehicle Research Center in the USA. A vehicle fitted with AB Dynamics’ driving robots, an OxTS motion pack and the Locata indoor positioning system performed path-following which was indistinguishable from normal operation under open skies with GPS which demonstrates that AB Dynamics’ robots can be used for high-precision driving both indoors and outdoors.
