Guided Soft Target (GST)
The GST – an essential tool for developing driver assistance technology
The Guided Soft Target (GST) is a pilotable target system which looks like another car to your test vehicle. The self-propelled GST platform carries a the Soft Car 360 impactable vehicle target, which separates 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.
All of our performance figures are quoted with a full-sized soft target onboard. The GST 100 is capable of a maximum speed of 100 km/h, with forward acceleration of 0.2g and 0.8g braking.
The GST 120 is designed to enable high-speed collisions to be carried out without causing damage to the test vehicle at a maximum speed of 120 km/h, with a forward acceleration of 0.25g and 0.8g braking.
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.
Our GST 120 has been fitted with a class-leading 4.8kWh battery, capable of providing sufficient power for a typical day on the track. They can be easily recharged between tests by connecting to a suitable supply at the track.
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.
The GST 120 has been fitted with 4-disc hydraulic braking systems with a failsafe emergency braking system as well as an ABS braking system to prevent wheel lock and optimise deceleration control.
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.
