Abstract: A method and a device are disclosed for determining data representative of the layout of a road in a two-dimensional Cartesian coordinate system, the coordinate system being associated with a vehicle travelling along the road. To this end, a first set of first points in the Cartesian coordinate system is determined on the basis of data representative of at least one image of the road environment in front of the vehicle. A second set of second points is determined in the Cartesian coordinate system on the basis of mapping data of the road environment of the vehicle. The data representative of the road layout are obtained on the basis of a part of the first points and a part of the second points.

Abstract: An internal combustion engine includes a combustion chamber with a cylinder head, a cylinder, and a piston. The internal combustion engine also includes at least one intake valve and at least one exhaust valve that are connected to the combustion chamber, a fuel injector that injects fuel into the combustion chamber, at least two ignition devices arranged in the combustion chamber, and control means that control the valves, the injector, and the ignition means. The control means operate the engine according to different combustion modes including a controlled ignition combustion mode, a compression ignition combustion mode, and an assisted compression ignition combustion mode. The control means activate the ignition means in the assisted compression ignition combustion mode.

Abstract: A method for manufacturing a decorative lining (HD) for a vehicle interior element (EH) is disclosed. Said method involves: —step (i) wherein the size of at least one edge (B11, B12) of two leather parts (PC1, PC2) is reduced on an inner face (FI1) and each reduced-size edge is folded over to form a fold (R1, R2) on each leather part (PC1, PC2); and —step (ii) wherein the leather parts (PC1, PC2) as well as a decorative insert (ID) that is inserted between the two leather parts (PC1, PC2) are coupled to the vehicle interior element (EH) by placing two edges (B21, B22) underneath the folds (R1, R2).

Abstract: The invention relates to a steering wheel comprising a steering wheel axis, a hub for fastening the steering wheel to a steering shaft being rotatable about the steering wheel axis and a steering wheel rim being connected to the hub and at least partially surrounding the hub in the circumferential direction, wherein a mounting projection for fastening an operating unit is formed on the steering wheel rim and wherein the mounting projection includes a coupling element for detachably fastening the operating unit as well as a positioning portion for fixing the operating unit in position. Furthermore, the invention also relates to an operating unit for such steering wheel as well as to a steering wheel assembly and a method of manufacture thereof.

Abstract: The invention relates to a method for controlling an automated driver-assistance system of a motor vehicle, which proposes a first automated driving mode disengaging at the end of a first transition phase and a second automated driving mode disengaging at the end of a second shorter transition phase, comprising the following sequence of steps: detecting, when the first mode is activated, a degradation of the driving context which does not allow same to continue beyond said first transition phase (100); assessing the level of attention to driving of the driver (200); checking the compatibility of the driving context with the implementation of said second mode and that said level of attention is no lower than a predefined minimum threshold (300); and directly activating said second mode (600) if said checking step is validated and if said driver performs a given action within a predetermined time period.

Abstract: A device (DA) analyses an immersive virtual reality system (SI) comprising a target (CD) that is securely fastened to an object (OM), detecting means (MD) that deliver a first signal representative of the current position of the target (CD), processing means (MT) that define images depending on the detected current position, and at least one image-displaying means (EA, PI). This device (DA) comprises a first sensor (C1) that generates a second signal when the object (OM) reaches a known position, a second sensor (C2) that generates a third signal when it detects a change in displayed image consecutive to the detection of the object (OM) in this known position by the detecting means (MD), and analysing means (MA) that determine first and second times of reception of the second and third signals then a first time difference between these first and second times of reception.

Abstract: The invention relates to a system for controlling the opening (4) of a motor vehicle door (2). The system (4) comprises: a housing (8); a handle (6) pivoting relative to the housing (8); an electric motor (18) for retracting and extending the handle of the openable body section; and a computer (22) which controls the power supply of the motor (18), and which switches from a standby mode to an active mode when the handle (6) is moved. The electric motor (18) generates a wake-up voltage during the movement of the handle (6) relative to the housing (8). The computer (22) is configured to switch from standby mode to active mode when it receives the wake-up voltage generated by the motor (18). Waking only takes place when the wake-up voltage reaches a threshold S of 5 mV.

Abstract: The invention relates to a structure of a front part of the bodyshell of a vehicle, notably a motor vehicle. According to the invention, the structure of the front part comprises reinforcing means secured to the A-pillar (5) and to the corresponding ends of the bodywork elements (1) so as to strengthen the connections between the A-pillar (5) and the bodywork elements (1) so as to prevent these connections from breaking in the event of a frontal impact of the vehicle. The invention applies to the automotive industry.
