AB Dynamics Launches Advanced Vehicle Testing
Leading automotive test system supplier AB Dynamics has launched a new Guided Soft Target vehicle, the GST120, capable of safe testing at highway speeds up to 120km/h. The GST120 brings a new level of performance to the company’s portfolio of ADAS test systems, incorporating ABS braking and the latest version of its sophisticated control software. The GST is an established test tool used to reproduce real-world driving scenarios on vehicle test tracks, essential in the development of driver assistance technology. It takes the place of a real vehicle during the evaluation of vehicle collision detection and crash mitigation systems, and can sustain a collision without damage to itself or other vehicles. The GST has comparable visual and radar characteristics to a real vehicle, enabling the test vehicle’s sensor systems to be reliably tested.
The GST consists of a dummy vehicle called the Soft Car 360 fixed to a remotely operated platform. The Soft Car is made from collapsible foam pieces. It has been adopted by Euro NCAP and NHTSA as the global vehicle target for ADAS testing. The platform carries the Soft Car dummy vehicle and can be overrun by another vehicle without damage.
AB Dynamics developed the GST120 in response to customer demand for a moving test vehicle target that can not only travel at highway speeds, but also stop rapidly to test increasingly complex high-speed scenarios used in the development of sophisticated driver assistance systems.
Key advances in the GST120 includes a 120 km/h top speed, an increased battery capacity, and an anti-lock braking system, all of which make the GST120 ideal for current and future test requirements, which are increasingly focussed on autonomous driving.
The GST120’s 4.8kWh battery is the largest of any platform available on the market, enabling extended uninterrupted testing. The addition of ABS enables rapid deceleration, which is required to safely test the performance of emergency braking systems in high-speed car-to-car following scenarios.
