AB Dynamics offers an accurate, choreographed control of all mobile features involved in ADAS and autonomous vehicle testing.

A new computer-controlled carrier for Vulnerable Road User (VRU) targets will help to bring ADAS and autonomous vehicle features to market more quickly and with greater confidence. Developed by leading automotive test system supplier AB Dynamics, LaunchPad enables, for the first time, accurate and repeatable control of all key mobile features of an ADAS or autonomous vehicle test scenario.

At the heart of the LaunchPad platform is a Power controller running AB Dynamics’ industry-standard Robot Controller RC Software. AB Dynamics’ proprietary TrackFi radio shares position data with other AB Dynamics controllers via the Synchro interface, which allows its motion to be precisely synchronised with the test vehicle and other ADAS targets. At just 65mm in height, the self-propelled chassis can carry pedestrian, cyclist, moped, scooter, or even animal dummies at speeds up to 50kph, enabling the testing of next-generation ADAS and autonomous systems in increasingly complex scenarios.  Its unique layout with all four wheels driven and steered gives it dynamic performance and stability that far exceed other small ADAS platforms on the market.

Unlike existing belt-driven platforms which only allow straight line paths, LaunchPad enables more varied and realistic interactions between test vehicles and a wide selection of typical VRU targets. Programming the trajectory of LaunchPad is simple thanks to the use of a graphical path generation utility, meaning complex scenarios with multiple moving objects can be created and run quickly and easily. The software is common with that used on the company’s well-established GST (Guided Soft Target) vehicle, already in widespread use for ADAS testing.

Mechanically, LaunchPad uses a robust aluminium chassis with shallow sloping sides, capable of being repeatedly run over, even by an SUV; in addition to providing a smooth over-run, the sloping sides present a low radar return. The motor-driven platform is highly manoeuvrable and batteries can be quickly replaced without removing the target, to support long periods of testing.
