Many mainstream cars are now equipped with advanced driver assistance systems (ADAS), and testing such systems requires special equipment and capabilities, often including the ability to control the relative position of the cars. With the priority recommendation of EuroNCAP (European New Car Safety Assessment Association) and NHTSA (National Highway Traffic Safety Administration) to be equipped with this technology to warn drivers of impending collisions, our robots have been widely adopted around the world and serve as First choice for ADAS testing.
ADAS test common requirements:
1. Can you follow a predetermined path with centimeter-level accuracy?
2. Precisely control the speed of the vehicle so that it follows the set speed curve?
3. Can you brake with a fixed deceleration?
4. Precisely control the relative distance between the two vehicles in the X and Y directions?
5. Is it possible to trigger a specific event when multiple conditions are met?
ABD solutions:
1. Path following----The path following function of the robot system can guide the vehicle to travel along a predetermined path with a control accuracy of 2cm at a speed of up to 220km/h.
2. Vehicle speed control----Provide a series of pedal robots to accurately control the speed of the vehicle, and the speed control error is less than 0.5km/h (depending on the quality of PID adjustment).
3. Precise braking-----Using a braking robot or CBAR, the stable and precise braking input required for automatic emergency braking (AEB) and forward collision warning (FCW) tests can be achieved. A range of control modes are available, including pedal stroke, pedal force and vehicle deceleration control.
4. Relative position control between vehicles - For many types of ADAS development and testing, precise synchronization of more than one vehicle is the key.
We provide many solutions for vehicle synchronization: (1) Longitudinal distance control: VBOX ADAS or RT Range; (2) Simultaneous horizontal and vertical distance control: Sync mode.
5. Settable trigger conditions—for example, when one or two trigger conditions are satisfied at the same time, or when the trigger conditions are met and remain for a period of time, the preset event will be executed.
Achievable ADAS tests:
◆ AEB test----EuroNCAP regulations;
◆ FCW front collision warning;
◆ Crossroad collision warning;
◆ Seat belt tensioning----caused by rear-end collision;
◆ NHTSA brake test procedures;
◆ Automatic parking system test;
◆ Pedestrian safety;
◆ Lane change assistant decision-making system---ISO1738;
◆ ACC adaptive cruise control----Cut in/Pull out test—ISO15622;
◆ AEB test - C-NCAP procedures;
◆ LDW lane departure warning---ISO17361 and NCAP;
◆ LKA, LSS lane keeping system test;
◆ BSD blind spot detection system test;
◆ AES automatic emergency steering system test.
We also offer a range of controllable soft target systems that can be synchronized with robotic or human-driven vehicles to reduce the risk of damage to test vehicles during ADAS testing.
Minimum setup equipment for ADAS Testing
Guided Soft Target
The Mk2 Guided Soft Target Vehicle ( GST ) is a next-generation platform designed for vehicle Advanced Driver Assistance System (ADAS) testing. The Mk2 GST has all the advanced features of the first-generation GST design, while still having an extremely low 100mm height. This guided soft target vehicle is a collaborative product between us and Dynamics Research Ltd ( DRI ). This product combines DRI's rolling platform concept with our leading path following and synchronous control technology.
The guided soft target vehicle (GST) was designed so that a high-speed crash could be achieved without significant damage to the test vehicle. It consists of a low profile chassis (LPC from which the vehicle can be rolled) and a detachable foam panel body (the Soft Car 360 harmonized Global Vehicle Target, GVT). As the test vehicle rolled over this low-profile vehicle, the wheels retracted into the undercarriage to protect the GST's suspension and minimize possible shock to the test vehicle's suspension.

Guided Soft TargetTM 120 (GST 120TM)
GST 120 is currently the most powerful target vehicle system available for testing advanced driving assistance systems (ADAS) in automobiles. The maximum speed of GST 120 can reach 120km/h, which is the only product in the market that can test the highway auxiliary system and auto drive system on the real highway.
The initial GST design of GST 120 shares many leading features with AB Dynamics and is widely used in Euro NCAP testing. Thanks to its height of only 100mm, it can operate at speeds of up to 120km/h and is equipped with a class leading 4.8kWh battery.
GST 120 can conduct high-speed collision tests without causing serious damage to the test vehicle. It consists of a GST platform that can be driven from above and a separate foam panel body (GVT, the global vehicle target of the Soft Car 360 harmonized standard). When the vehicle passes the platform, the wheels will retract into the chassis to protect the suspension of the platform and generate as little impact input as possible on the suspension of the test vehicle.
By using an electric motor with an onboard battery to propel the vehicle, the control system of the GST platform can accurately guide the vehicle along a pre programmed route at a specified speed. The batteries used to power the system will provide sufficient power for a typical day of testing, and during testing intervals, they can also be connected to a suitable power source for easy charging.
The controller will use the position feedback provided by the high-precision GPS calibrated inertial navigation system to achieve precise path following control. The time signal provided by GPS devices will be used to ensure precise millisecond level synchronization, which is essential for precise and repeatable collisions and close range passing scenarios.
GST can be controlled through the radio of the same remote base station used in the AB Dynamics standard unmanned driving test system. By using the same system as AB Dynamics' robots, GST can be used simultaneously with other vehicles to create complex multi vehicle testing scenarios. AB Dynamics' mature path following and synchronization control technology enables seamless integration of the GST 120 with all existing AB Dynamics track testing products.

Soft pedestrain target
From 2016, EuroNCAP testing will include automatic emergency braking (AEB) trials with dummies instead of real pedestrians. Such trials require the use of a controllable pedestrian model that can be synchronized with the test vehicle. Our Soft Crash Pedestrian Target (SPT) uses a horizontal belt propulsion system, which eliminates the need for a high-altitude gantry (which, according to EuroNCAP, affects test results). This also makes the Soft Crash Pedestrian Target a portable system that can be quickly installed on any test track.
The soft-collision pedestrian target uses the standard steering robot motor and controller as the drive unit, and the easy-to-use RC software is used to set the soft-collision pedestrian target, which is convenient for existing robot users to be familiar with. Users can reduce the expense of the pedestrian system by using their existing steering robot (SR60 or SR60 Torus), which can be easily and quickly installed and removed from the pedestrian system. Alternatively, there is an option with a built-in dedicated motor.
