ESTIMACIÓN DE LA AUTONOMÍA DE UN VEHÍCULO ELÉCTRICO SEGÚN EL ESTILO DE CONDUCCIÓN

En este trabajo se presenta un proceso para la estimacion de la autonomia de vehiculos electricos en funcion del comportamiento de los conductores al volante. Para ello, se extraera una serie de parametros directamente del GPS y de los acelerometros de smartphones en una ruta urbana realizada por 11 conductores. De ellos se elaboraran unos indicadores (perfil de conduccion) que, junto con el consumo real del vehiculo en las rutas, seran empleados para el entrenamiento de una red neuronal cuyo objetivo sera la prediccion de variables como el confort de los pasajeros y el consumo esperado en condiciones de trafico reales. Este modelo ademas es extrapolable al ambito de la seguridad, ya que existe una relacion directa entre eficiencia energetica y agresividad en la conduccion.

GUIADO DE VEHÍCULOS AUTÓNOMOS MEDIANTE LIDAR 3D SIGUIENDO UN ELEMENTO DE REFERENCIA

Every transportation plan in the medium and long term consider autonomous vehicles as a key solution for transport, which will reduce to a minimum traffic accidents and congestion, maximizing the use of the road. However, at present, these vehicles are still under development and they are not with acceptable figures for the placing on the market. A fundamental element on today obstacle detection is the laser scanner, which provides a three dimensional mesh that can represent all objects that are at a distance of 200 meters from the vehicle. Furthermore, the combination of GPS with inertial systems allows precise positioning on the road, if necessary reinforced with computer vision to achieve lane level positioning. However, there are situations, such as tunnels or urban roads with poor reception of GPS signals that make this positioning can be complicated, so much so that the autonomous vehicle requires human intervention to maintain the trajectory. This article describes a use of laser scanner technology to support positioning and maintaining the position even when the GPS and inertial systems are not sufficient to maintain the route. This system will be complementary to conventional guidance systems and works in parallel without interference obstacle detection system for autonomous vehicles. It has also been tested and validated in real situations autonomous vehicles driving at high speeds on real roads.

DISPOSITIVO UNIVERSAL PARA EL CONTROL AUTOMÁTICO DE LA DIRECCIÓN DE UN VEHÍCULO

ABSTRACT: Road vehicle steering automation is an essential part of any kind of application that involves autonomous driving or navigation. Vehicle manufacturers can perform this automatic control because they have access to the vehicle control unit and the internal communication bus. However, this solution involves knowledge of communication protocols and a certain electronic architecture. This paper presents a device able to control the steering of a road vehicle without necessity of the intervention of human drivers. This device can be installed in any kind of vehicle independently of the kind of assistance of the steering only by attaching a single mechanical coupling element between the device and the steering column. The architecture of the device also allows switching between manual and automatic control electronically at any moment. The developed device can be used to support any kind of Advanced Driver Assistance System that requires automatic steering control up to autonomous driving.
