Environment Simulation for Driver Assistance Services

Application Area

Advanced driver assistance systems (ADAS) can be based upon camera systems, radar sensors, ultrasonic sensors, etc., in order to react to other vehicles and the environment. Adaptive cruise control (ACC), and assistants for intersection braking, parking, lane changing and lane keeping, are examples of ADAS.

One example is a lane keeping assistant which monitors the road ahead of the vehicle by using a video camera and actively controls the steering system to keep the vehicle between the road lanes. Validating such a functionality requires numerous test runs to be repeated under different conditions.

Some other examples:

• Traffic sign recognition
• Lane departure warning systems
• Parking assistant
• Car2x

dSPACE Solution

dSPACE provides realistic simulation scenarios for hardware-in-the-loop testing so that many tests drives on the road can be replaced with virtual test drives in the laboratory. The HIL simulation can be based, for example, on real navigation date or data from a video camera integrated in the ECU under test. The dSPACE Automotive Simulation Models (ASM) tool suite offers models for the vehicle and its environment sensors, the driver, the road and the traffic environment. Additional, third-party models can be integrated. dSPACE AutomationDesk, the HIL test software, enables automatic simulation runs and overnight tests, resulting in increased test depth and a greater maturity of driver assistance systems.
