Abstract

The invention relates to a system for integration in vehicles and a method for operating said vehicles which permits changes in the behaviour thereof in order to enable the driver to continue travelling in cruise-control driving mode without having to deactivate it, i.e. by braking when encountering a trajectory determined by a curve. This is achieved due to the vehicle communicating with a system of three nodes established on the curve, which determine the speed with which the curve should be travelled. The information is provided to the vehicle and executed by its ECM, and electro-hydraulic actuators will make the appropriate braking or accelerating adjustments so that the driver can focus 100% on the proper handling of the steering wheel. The method permits a comfortable and safe handling in conjunction with the cruise-control driving mode.

DESCRIPCIÓN DETALLADA DE LA INVENCIÓN DETAILED DESCRIPTION OF THE INVENTION
Los detalles característicos de la presente invención, se muestran claramente en la siguiente descripción y en las figuras que se acompañan, las cuales se mencionan a manera de ejemplo, por lo que no deben considerarse como una limitante para dicha invención. Breve descripción de las figuras: The characteristic details of the present invention are clearly shown in the following description and in the accompanying figures, which are mentioned by way of example, so they should not be considered as a limitation for said invention. Brief description of the figures:
La figura 1 describe un vehículo (V) que se encuentra en modo de conducción "crucero" y que paulatinamente llegará a una curva (A), pasando de manera cercana por los nodos l, 2 y 3. Figure 1 describes a vehicle (V) that is in "cruise" driving mode and that will gradually reach a curve (A), passing closely through nodes 1, 2 and 3.
La figura 1.1 ilustra a un vehículo acercándose al área de cobertura inalámbrica establecida por el nodo 1. Figure 1.1 illustrates a vehicle approaching the wireless coverage area established by node 1.
La figura 1.2 describe al vehículo acercándose a los nodos 1 y 2, que se encuentran antes de llegar a la curva A. El nodo 2 mantiene un área de cobertura inalámbrica enfocado, apuntando a la parte frontal al vehículo que posteriormente tendrá que cruzar para llegar a dicha curva. Figure 1.2 describes the vehicle approaching nodes 1 and 2, which are located before reaching curve A. Node 2 maintains a focused wireless coverage area, pointing to the front of the vehicle that will subsequently have to cross to arrive to said curve.
La figura 1.3 ilustra al mismo vehículo una vez recorrida la curva y que espera cruzar el área de cobertura inalámbrica del nodo 3.  Figure 1.3 illustrates the same vehicle once it has traveled the curve and expects to cross the wireless coverage area of node 3.
La figura 2 ilustra el funcionamiento interno del sistema de conexión entre los elementos de una infraestructura de nodos instalados en una ruta con curva. Dichos nodos conforman un conjunto de 3 dispositivos para cada curva (como ejemplo, curva A), donde se conectan con el Coordinador de señales encontrado en el interior del vehículo que está próximo a acercarse a estos nodos. El coordinador enviará a la computadora del vehículo señales necesarias para activar actuadores eléctricos, hidráulicos y mecánicos, y así realizar los ajustes en velocidad para el modo crucero del vehículo. Figure 2 illustrates the internal operation of the connection system between the elements of an infrastructure of nodes installed in a route with a curve. These nodes make up a set of 3 devices for each curve (as an example, curve A), where they connect with the Signal Coordinator found inside the vehicle that is close to approaching these nodes. The coordinator will send signals necessary to activate electric actuators to the vehicle's computer, hydraulic and mechanical, and so make adjustments in speed for the cruise mode of the vehicle.
La figura 2.1 describe los elementos internos de los sistemas Nodo y Coordinador. En el primer sistema encontramos un controlado^ emisor y sensor que estarán comunicándose entre sí para enviar las señales correspondientes al receptor del Coordinador. Una vez recibidas dichas señales, y a su vez procesadas por el controlador, se comunicarán por medio de una interfaz requerida por el vehículo, para ser leídos correctamente por la computadora de éste. la figura 3 describe el funcionamiento y toma de decisiones de los diferentes sistemas involucrados, donde un vehículo en modo crucero es detectado por un nodo 1 y así cargar información correspondiente al vehículo, donde a su vez, el nodo 2 dará una confirmación de información cargada por el nodo 1 y los actuadores del vehículo comenzarán a trabajar para llegar a la velocidad determinada para desplazarse durante la curva. Al llegar al nodo 3 los valores de actuadores del vehículo serán restaurados para alcanzar de nueva cuenta la velocidad original del modo crucero antes de llegar a la curva. La figura 3.1 ilustra todo lo descrito en la figura 3 pero con una variante donde el coordinador registró la velocidad alcanzada realmente por el vehículo. Figure 2.1 describes the internal elements of the Node and Coordinator systems. In the first system we find a controlled transmitter and sensor that will be communicating with each other to send the corresponding signals to the receiver of the Coordinator. Once received these signals, and in turn processed by the controller, will communicate through an interface required by the vehicle, to be read correctly by the computer of it. Figure 3 describes the operation and decision making of the different systems involved, where a vehicle in cruise mode is detected by a node 1 and thus load information corresponding to the vehicle, where in turn, node 2 will give a confirmation of information loaded by node 1 and the actuators of the vehicle will begin to work to reach the determined speed to move during the curve. Upon reaching node 3, the vehicle's actuator values will be restored to reach the original cruising mode speed again before reaching the curve. Figure 3.1 illustrates everything described in figure 3 but with a variant where the coordinator recorded the speed actually reached by the vehicle.
A continuación se describe uno de los métodos donde se puede utilizar la presente invención. Next, one of the methods where the present invention may be used is described.
La computadora de un vehículo está constantemente recibiendo datos de las distintas entradas: estado del vehículo, información de manejo, etc. El sistema utiliza el modo de conducción "crucero" de los automóviles para complementar la información referente al desempeño de manejo en rutas que incluyen curvas y que el conductor forzosamente tendrá que desactivar para evitar algún accidente, ya sea por volcamiento, debido a las altas velocidades. De esta manera el sistema al llegar paulatinamente a estos sectores curvos del trayecto, ajustará las velocidades determinadas al veh.culo y el conductor podrá continuar avanzando sin desactivar el modo "crucero" para enfocarse 100% en dar un buen desempeño al volante. The computer of a vehicle is constantly receiving data from the different inputs: vehicle status, driving information, etc. The system uses the "cruising" mode of the cars to complement the information regarding driving performance on routes that include curves and that the driver will necessarily have to deactivate to avoid an accident, either due to rollover, due to high speeds . In this way, the system, when it reaches these curved sections of the path gradually, will adjust the speeds determined to the vehicle and the driver. you can continue advancing without deactivating the "cruise" mode to focus 100% on giving a good performance at the wheel.
