Abstract: A method and device lock a guiding system of a vehicle guided by at least one rail. The locking device includes first and second cylinders combined with guiding devices belonging to the guiding system of a steering axle. Each of the cylinders contains at least two characteristic configuration states: a first configuration state placing the guiding device with which the cylinder is combined in a first guiding state, and a second configuration state placing the guiding device with which the cylinder is combined in a second guiding state. A power supply supplies power to the cylinders to switch the configuration state. The power supply is coupled with a rotary member, the rotation of which is mechanically linked to the movement of the vehicle, such that a change in the direction of rotation of the rotary member is transmitted to the power supply and switches the configuration state of the cylinders.

Abstract: A system of assembling storage devices in the form of electrical energy modules includes two pairs of positive and negative terminals for each module, in which each of the pairs of positive and negative terminals is distributed over at least one of the external faces of each module, thus forming a terminal strip of the module. At least one interconnection block can be inserted onto part of each of the terminal strips of two separate modules and itself includes at least two pairs of anchoring points so as to form an assembly block, either by stacking the storage modules or by juxtaposing the same. At least two anchoring points of each interconnection block are in electrical contact, while stiffening the assembly, in a manner complementary to the other anchoring points.

Abstract: 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.

Abstract: A method and a device for monitoring the presence of at least one guide rail for a guided vehicle, include a first detector located downstream of a wheel. The detector is capable of detecting the presence of the rail and of transmitting a first signal relating to the presence of the rail to a monitoring member. A second detector located upstream of the wheel can be connected in parallel to the first detector and is capable of detecting the presence of the rail. The second detector can communicate a second signal, relating to the presence of the rail, to the monitoring member.

Abstract: An expansion device for a rail suitable for guiding a wheel of a vehicle along a track, and a method for installing the expansion device. Specifically, the rail has a portion of track formed of a series of elements in the form of transverse track plates whose cross section is the same as that of the rail. The track plates are arranged in longitudinal succession along the portion with compressible modules inserted between them.

Abstract: 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.

Abstract: 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.

Abstract: 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 (Communication Based Train Control) type. The system includes: a signaling control unit of the AWS (Auxiliary Wayside System) 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.

Abstract: 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. A monitoring device in a vehicle of the vehicle network is 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.

Abstract: 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.
