Modeling of Detection and Avoidance of Obstacles as a Contribution to Automotive Applications

Improvements in safety have reduced fatalities in vehicle collisions, systems as airbags and ABS has reduced accidents even their severity. Lately Active Safety Systems as Adaptive Cruise Control (ACC), Predictive Emergency Brake, Lane Change Assist and Blind Spot Detection Systems has been developed searching for avoiding accidents. Reductions on collision speeds by at least 5 km/h helps to reduce the severity of injuries in frontal collisions.

This paper will focus on four main subjects. In the first time a comparison of sensors available in the present market is presented. Secondly, an idealized time responses during braking will be shown as a development platform for this project. Following, a vehicle model, which includes sub-models for the tires and a passive suspension, will be presented. Finally, an integrated model for dangerous obstacles detection [1] will be shown.
