I developed a validation software for Advanced Driver Assistance Systems, or ADAS, are systems to help the driver in its driving process. My project focused on auto braking system at inter-section. I developed a software to validate this system by using Lab-View. This software is connected to sensor that detects a passing car. It calculates a speed of the passing car and let a dummy move at intersection at a certain timing so that car crashes into a dummy. As it has the ADAS system, a car should detect the dummy and stops automatically.
