Abstract

Los métodos y sistemas para determinar y controlar la velocidad de desplazamiento de un vehículo en una carretera determinan una pendiente de la carretera en intervalos definidos a lo largo de la carretera; calculan la velocidad máxima del vehículo en línea recta para cada intervalo definido basándose en la pendiente determinada y en los datos de desempeño del vehículo; determinan un radio de curvatura y un peralte de la carretera para cada intervalo definido; determinan un coeficiente de fricción lateral para un sistema de vehículos/carreteras; calculan una velocidad máxima del vehículo en curvas para cada intervalo definido basándose en la curvatura, el peralte y el coeficiente de fricción lateral; calculan la velocidad de desplazamiento para cada intervalo definido basándose en la velocidad máxima del vehículo en línea recta y la velocidad máxima del vehículo en curvas, y controlan la velocidad del vehículo para que no exceda la velocidad de desplazamiento calculada para cada intervalo definido.
