This master thesis focus on active safety for the automotive industry. The aim is to test an inexpensive implementation of some common functions realized using a cellphone to gather data. A Matlab Simulink model is developed for the purpose, and then the agility of the model is tested by generating c code and running it on a single board computer. A robust lane detection algorithm is developed by using Hough lines. To better cope with curves in the road, the Hough lines are combined with a parabolic second degree fitting. The Hough lines are also used for a Lane Departure Warning system. Using edge filtering and connected component labeling an obstacle warning is implemented. Overall the model works well and is fast enough to meet the real time requirements when run on a computer. On the Raspberry Pi 2 chosen as the single board computer the processing is unfortunately not quite fast enough for high speed driving. However when the object detection is removed the Raspberry Pi 2 meets the real time requirements as well.
