20110029180 | Device for Measuring the Movement of a Self-Guided Vehicle - A device for measuring the movement of a self-guiding vehicle, that has an enhanced measuring reliability, in particular during an adhesion loss and independently from the travel profile of the vehicle in terms of slope, turn and slant. To this end, the device for measuring the movement of a self-guiding vehicle includes on board thereof two accelerometers coupled to a movement calculator, wherein each accelerometer includes two measurement axes on which are measured projections of a vehicle acceleration resultant. The four measurement axes of the accelerometers are adjusted so that the calculator provides, from the four projection measures, at least one very accurate longitudinal acceleration value of the vehicle at each point of a route including both slopes and turns. | 02-03-2011 |
20100324776 | Device for Measuring the Movement of a Self-Guided Vehicle - The invention relates to a device for measuring the movement of a self-guided vehicle, that comprises onboard thereof: at least one accelerometer provided with a measurement axis arranged in the longitudinal direction of a potential main rectilinear movement of the vehicle, a first tachometer provided on an axle upstream from the vehicle in the longitudinal direction, a second tachometer provided on a second axle downstream from the vehicle in the longitudinal direction, wherein measure signals from the accelerometer and from the first and second tachometers are supplied to a computing unit. Accordingly, it is advantageously possible to determine the speed and the position of the vehicle on a vehicle route while taking into account an adhesion loss of at least one of the axles as well as an exact slope and turn effect on a vehicle route that does not remain rectilinear and changes horizontally and/or vertically. | 12-23-2010 |
20100090069 | Anticollision Control System for a Vehicle - An anti-collision control system for one or more vehicles fitted with an onboard automatic pilot (self-guiding) allowing for bi-directional movements on a single track under the control of a ground-based automated traffic control unit of the CBTC type. The system includes: a signaling control unit of the AWS type for controlling ground signals on a section of a single-direction circulation lane; a first default control means based on which the signaling control unit imposes a single-direction movement to the vehicle running on the section of a single-direction circulation lane in order to avoid any collision with another vehicle controlled solely by the signaling control unit of the AWS type, i.e. independently from the ground-based automated traffic control unit. A first advantage of the invention is that a second control mode can be activated, in which a displacement of the vehicle piloted in opposite directions on a portion at least of the section of the initially single-direction circulation lane, can be initiated by way of a request for a control priority demand sent by the automated traffic control CBTC to the AWS signaling control unit, which in turn sends back an authorization (or refusal) signal RESP to said request. | 04-15-2010 |
20100049830 | High Availability Network System - A communication system adapted for a vehicle includes a network for communication between at least two communication interfaces respectively connected to a first controller which manages/runs a control application and a second controller which also manages/runs the control application. The communication interfaces have, per controller, at least one communication port from which a communication link is possible. The communication link is a PLC (Power Line Communication) link having at least two electrically conductive links connected to each of the respective communication ports through at least one coupling transformer, for a control application transmission between the two communication interfaces. | 02-25-2010 |
20090138149 | Energy-Regulating System for a Vehicle - An energy-regulating system for a vehicle, suitable for use in a mass transportation system between a departure station and an arrival station along a predetermined route, has advantageously a high-power electrical storage device placed on board the vehicle, supplying power to the vehicle, at least during acceleration. The energy recovered during braking of the vehicle is stored in the storage device. At least the departure station includes an electrical charging area capable of charging the storage device of the vehicle and activated in a charging mode as soon as the residual energy of the storage device of the vehicle is below a variable threshold dependent on an early estimate of the energy balance of the vehicle at least up to the arrival station. | 05-28-2009 |
20090063700 | Communication system between a vehicle network and a wayside network - A system for communications between a vehicle network and a wayside network includes a router in the vehicle network configured to manage routing of data over one of at least two clients, and a radio-frequency based communication network for providing a connection between each client and an access point linked to the wayside network. Monitoring means in a vehicle of the vehicle network are configured to control a quality of the connection in order to configure the router so that one of the clients is selected for the data routing between the vehicle and the wayside network. | 03-05-2009 |
