|ADAS (Advanced Driver Assistance Systems)|
In recent years, the automotive industry has been working on the development of Advanced Driver Assistance Systems (ADAS), comprising of all the systems that monitor the environment with the aim of avoiding collisions.
To test these systems, it is necessary to reproduce real-life traffic situations, where different cars interact with each other. Therefore a system which allows simulation of the required scenarios has been developed in order to perform ADAS testing activities in a safe and realistic environment. This approach is necessary to lower the risk of the equipment getting damaged and more importantly prevent human injuries by lowering the probability of contact between vehicles in the event of electronic system failures while testing.
The other issues of highest importance are accuracy and repeatability. Hence accurate GPS Inertial Units such as the RT3002 Inertial GPS Navigation Systems are used for high quality measurements of various physical parameters like position (x, y and z), velocities (x, y and z), accelerations (x, y and z) etc. For accurate repeatability ABD steering, braking and accelerator robots are used for driving the vehicles. These robots can be interfaced with the OXTS on-board Inertial and GPS navigation system for using 2cm-accurate GPS positioning to drive a vehicle through a pre-defined course over ground.
The RT-Range system can be used for accurate measurement of the relative motion between two vehicles and the precise measurement of lane position. The systems output all measurements of the ‘Hunter’ and ‘Target’ vehicle in real-time on CAN bus and PC with high accuracy. The position of the vehicle can be measured with up to 2cm accuracy and speed measurements are accurate to 0.05 km/h which is essential for ADAS testing.
