Use of driving simulators for advanced driver assistance Systems evaluation in emergency situations
2012
Introducing advanced driver assistance systems in cars has numerous consequences, particularly on drivers' behavior and their interaction with the vehicle. The expected safety benefits of assistance systems can thus be jeopardized. In order to assess the actual safety benefits, driving simulators offer a safe and cheap alternative. This doctoral work relies on experiments carried out on driving simulators with different assistance systems. A first experimental part focuses on longitudinal control assistance: we studied drivers' familiarization with a Forward Collision Warning system in critical situations. A second experimental part focuses on lateral control assistance: we studied drivers'…
Availability, demand, perceived constraints and disuse of ADAS technologies in Spain: findings from a national study
2019
Advanced Driver Assistance Systems (ADAS), created for enhancing the driving experience and actively preventing road crashes, have been progressively incorporated in vehicle designing essentially during the last decade. However, the literature has shown how some of these assisting technologies are not used by drivers in tandem with their potential. The aims of this study were, first, to examine the availability and demand of ADAS technologies among Spanish drivers and, secondly, to explore the perceived constraints and discouraging reasons for avoiding the use of ADAS available in their vehicles. For this national cross-sectional study, data from 1,207 Spanish drivers were analyzed. The res…
An Embedded Real-Time Automatic Lane-Keeping System
2007
Advanced Driver Assistance Systems (ADAS) are safety systems capable of identifying an unavoidable dangerous scenario and reacting coherently. An automatic lane-keeping system is designed to prevent dangerous events when the driver left inadvertently his/her own lane. In this paper a real-time automatic lane-keeping system is proposed. The main features of the system are the lane markers location process as well as the generation of the vehicle's steering angle. The system has been prototyped using the Celoxica RC203 board, equipped with a Xilinx Virtex II FPGA, for real-time processing of real motorway scenes coming from a CCD camera on a moving vehicle. The required processing time is 25,…
A real-time non-intrusive FPGA-based drowsiness detection system
2011
Automotive has gained several benefits from the Ambient Intelligent researches involving the deployment of sensors and hardware devices into an intelligent environment surrounding people, meeting users’ requirements and anticipating their needs. One of the main topics in automotive is to anticipate driver needs and safety, in terms of preventing critical and dangerous events. Considering the high number of caused accidents, one of the most relevant dangerous events affecting driver and passengers safety is driver’s drowsiness and hypovigilance. This paper presents a low-intrusive, real-time driver’s drowsiness detection system for common vehicles. The proposed system exploits the ‘‘bright p…
