The method comprises the generation of a representation of musical contents which is centred on a first musical content, and a reading of the musical content on which the representation is centred. The musical content on which the representation is centred is read so long as an action is not undertaken by the user. If an action ending the reading of the musical content in progress is undertaken by the user, a new musical content is read. If an action not ending the reading of the musical content in progress is undertaken, the action is taken into account. If the reading of the musical content on which the representation is centred is terminated, a new musical content of the representation is read. The representation is modified with each new reading of a musical content so as to be centred on the new musical content read.

The hydraulic module comprises a pump casing (11) fixed to the housing (2a, 2b) of the transmission (1) and housing a single hydraulic motor (12) comprising a hydraulic distributor (14), a barrel (15), a pump cam (13) fixed to the housing (5) of the axle differential (3) and a plurality of radial pistons (16) in contact via one of the ends thereof with the internal surface of the pump cam (13) and each intended to slide in one of the cylinders (15a) of the barrel (15), said cylinders (15a) being in fluidic communication with the hydraulic distributor (14).


The invention relates to a method for controlling a triple-phase electrical machine (2) of a motor vehicle, said machine being supplied with chopped voltages. Said method includes a step of determining current set points for each phase of the electrical machine (2) on the basis of a torque request from the driver. The method includes the following steps, during which: the voltages of each phase of the electrical machine (2) are determined on the basis of the reference currents for each phase, of the measurements of the currents of each phase, and of the measurement of the magnetic rotation speed of the electrical machine (2); the attenuation voltages of current oscillations from each phase of the electrical machine are determined on the basis of the reference currents, measurements of the currents of each phase, as well as the measurement of the rotation speed of the magnetic field of the electrical machine (2); and set points for final voltages for supplying power to the electrical machine are determined by adding the power supply voltages, related to each phase, with the attenuation voltages related to the corresponding phases.


The fuel injection pump, notably a high-pressure fuel injection pump for an internal combustion engine, notably a motor vehicle internal combustion engine, comprises on the one hand, a plunger including a plunger body (10) and a roller (11) mounted to rotate on the plunger body (10) and able to collaborate with a cam secured to a rotary shaft of the engine so as to bring about a translational movement of the plunger, and on the other hand a guide housing (13) guiding the plunger body (10) during the translational movement of the plunger intended to be imparted by the cam. The pump comprises a component (15) for supplying the inside of the guide housing (13) with lubricant. The component (15) is able to collaborate with the plunger body in order to remove the degree of freedom of the plunger to rotate about the axis of translation (X) along which the translational movement of the plunger is effected.


The invention relates to a charge air cooler (100) for an air intake system (14) of an engine (12) supercharged by a turbocharger (18), the cooler (100) comprising: an exchanger (110); an inlet box (120) for guiding the charge air from an inlet (101) of the cooler (100) to the exchanger (110); and an outlet box (130) for guiding the charge air from the exchanger (110) to an outlet (102) of the cooler (100); the inlet box (120), the exchanger (110) and the outlet box (130) defining a filling volume (Vu) designed so as to receive the charge air, the cooler (100) being characterised in that it comprises control means (140) designed so as to vary the filling volume (Vu).


The invention relates to a system (1) for detecting a lack of vigilance on the part of a driver of a motor vehicle (2), the system comprising a stereophonic sound generator (14) configured to control at least two loudspeakers (5a, 5b, 5c, 5d) in order to simulate a sound coming from a virtual sound source (20) which is movable relative to the drivers seat (3), the sound stage-generator being configured to emit a stereophonic sound pattern from a mobile virtual source when the level of vigilance detected (vigil) is less than a given threshold.

The invention relates to an assembly of an air guide (10) to a structural element of a motor vehicle using fixing means (30). The latter comprise a first fixing element (31) secured to the air guide (10) and a second fixing element secured to the structural element, collaborating in the same direction of attachment. The first fixing element (31) is secured to the air guide by retaining means (40) configured to break in the event of an impact. The lateral edges (11) of the air guide have guide parts (50) situated substantially facing the second fixing elements, which guide parts are configured to guide a lateral edge of the structural element if the retaining means (40) break as a result of a movement of the air guide toward the structural element in the event of an impact. The extent to which the air guide (10) moves back toward the structural element is thus limited.

Hydrogen Mobility Europe 2 (H2ME 2) brings together action in 8 European countries to address the innovations required to make the hydrogen mobility sector truly ready for market. The project will perform a large-scale market test of hydrogen refuelling infrastructure, passenger and commercial fuel cell electric vehicles operated in real-world customer applications and demonstrate the system benefits generated by using electrolytic hydrogen solutions in grid operations. H2ME 2 will increase the participation of European manufacturers into the hydrogen sector, and demonstrate new vehicles across a range of platforms, with increased choice: new cars (Honda, and Daimler), new vans (range extended vehicles from Renault/Symbio and Renault/Nissan/Intelligent Energy) and a new medium sized urban delivery truck (Renault Trucks/Symbio). H2ME 2 develops an attractive proposition around range extended vehicles and supports a major roll-out of 1,000 of these vehicles to customers in France, Germany, Scandinavia and the UK. 1,230 new hydrogen fuelled vehicles will be deployed in total, trebling the existing fuel cell fleet in Europe. H2ME 2 will establish the conditions under which electrolytic refuelling stations can play a beneficial role in the energy system, and demonstrate the acquisition of real revenues from provision of energy services for aggregated electrolyser-HRS systems at a MW scale in both the UK and France. This has the further implication of demonstrating viable opportunities for reducing the cost of hydrogen at the nozzle by providing valuable energy services without disrupting refuelling operations. H2ME 2 will test 20 new HRS rigorously at high level of utilisation using the large vehicle deployment. The loading of stations by the end of the project is expected to average 20% of their daily fuelling capacity, with some stations exceeding 50% or more. This will test the HRS to a much greater extent than has been the case in previous projects.
