Guided Soft Target
The GST – an essential tool for developing future driver assistance technology
The Guided Soft Target is a pilotable target which looks like another car to your vehicle. The self-propelled platform carries a soft vehicle target (Soft Car 360) which is aerodynamically stable yet can separate into lightweight parts on impact, avoiding damage to the test vehicle.
Rugged, dependable platform
AB Dynamics has used its well-proven motion control technology in the GST, with cutting-edge motor and battery technology to ensure that it withstands repeated impacts and long days on the track.
Safe, high-capacity batteries
We’ve designed the GST such that the onboard batteries will power it for a full day of testing. There’s no need to swap battery packs.
Our GST battery packs are all certified safe for air freight transportation under the UN38.3 battery transportation safety testing requirement, having passed an extensive set of tests including withstanding extreme temperatures, simulated altitude testing as well as shock and vibration to 200Hz at 8g. The batteries and cells are charge cycled over 50 times to ensure electrical safety and the integrity and temperature is monitored constantly during charging and in operation.
All of our performance figures are quoted with a full-sized soft target onboard. The GST is capable of a maximum speed of 100kph, with forward acceleration of 0.2g and 0.8g braking.
Using our proven path-following technology, the GST offers unbeatable position and speed accuracy.
The GST has a fail-safe backup brake system, together with a vigilant safety controller. Watchdog signals are used to ensure all system elements are fully functional, and in the event of a problem, dual brake circuits ensure that it can be stopped.
Synchronisation using a common software environment
This allows perfect synchronisation with your test vehicle, whether driven by robots or a human driver. Multiple tracker objects can be synchronised with the subject vehicle, allowing complex ADAS scenarios to be created.
Soft Car 360 - Global Vehicle Target (GVT) for harmonised testing
The Soft Car 360 vehicle target is licensed by AB Dynamics for production in Europe and has been adopted by Euro NCAP and NHTSA as the Global Vehicle Target for harmonised ADAS testing.
It can be assembled in less than 10 minutes with no tools required. Lightweight but durable vinyl-covered foam panels make up the structure, which is covered by a photo-realistic skin.
The structural design of the Soft Car 360 body results in unparalleled aerodynamic stability, with almost no movement at up to 100kph. This stability is essential, ensuring that the target is reliably recognised by test vehicles’ ADAS sensors.
Accurate resemblance from all directions
With a combination of photo-realistic outer skin and built-in radar reflectivity, the Soft Car 360 body has been extensively tested by AB Dynamics and its customers to ensure that it is recognised as a real car by ADAS sensors.
The standard vehicle body is a Fiesta, but AB Dynamics can also offer a Smart Car, and custom bodies are available on customer request.
