Chinese Driverless Test System
Take the driver out of the vehicle and testing efficiency, precision and repeatability.
Product overview
AB Dynamics’ Driverless Test System uses driving robots and path following technology to guide the test vehicle along a pre-defined path with precise control of position, speed, and time. This system can handle various testing applications, such as vehicle dynamics and durability and misuse testing.
Customers commonly use driverless systems to accelerate lifetime vehicle testing, removing the risk of injury to their test drivers. With accurate path following and speed control, the robot will drive continuously on the harshest of surfaces, such as pothole drives, rough concrete, off-road and Belgian block, without the need to pause. The Driverless Test System safely manages multi-vehicle applications, meaning two operators can control over five vehicles, further increasing proving ground efficiency. Customers also use driverless systems to perform misuse tests, for example to perform repeated collisions with sandbanks, curbs, and severe potholes, achieving far higher accuracy and safety by the removal of humans from the test vehicle.
Specifications
The Driverless Test System consists of four main components: driving robots, the path following system, the safety system, and the control software.
- Driving robots are devices installed in the test vehicle to control steering, throttle, brake, and gear, enabling the test vehicle to follow a desired path and speed profile with high accuracy and repeatability. A Flex-0 controller can alternatively be used to control the vehicle via its CAN interface.
- The path following system communicates with the driving robot and the control software to provide feedback and corrections, allowing the test vehicle to follow complex trajectories and manoeuvres, such as lane changes, overtaking, and emergency braking.
- The safety system monitors the status and performance of the test vehicle and the driving robot. The safety system also provides a remote emergency stop function that can be activated by the operator or by the control software.
- The control software runs on a laptop or tablet and provides the user interface for the system. This software allows the user to create, edit, and execute test scenarios and paths. It also displays the real-time status and feedback of the test vehicle and the driving robot.
