Caracterización de los sistemas de actuación para vehículos altamente automatizados

Abstract

Automated driving requires proper simulation models for the research and deve- lopment of decision and control strategies. Currently, real testing platforms are obtained through the modification of comercial vehicles, where electro-mechanical actuators or robots are fixed to the steering wheel or gas/brake pedals. During the setting of the gains of high level control, remarkable differences may occur between reality and simulation due to improper models of the low level control architecture. In this project, a wide overview about the state-of-art of the low-level control techniques used not only in academic papers, but also in the industry, is presented. Aditionally, a validation methodology for the low level actuator system model is developed based on openloop trials. Finally, a comparison between real and simulated behaviours of the modelled actuator system is carried out, analysing the performance of the proposed methodology in a real case scenario with an automated vehicle.
