    Abstract: The invention relates to a method for evaluating the distance (d) between an identifier (20) fitted with a first wireless communication module (24) and a vehicle (10) fitted with a second wireless communication module (14), including the following steps: establishing a wireless connection (L) between the first wireless communication module (24) and the second wireless communication module (14); estimating said distance (d) on the basis of a propagation time of the electromagnetic signals involved in the wireless connection established (L); when the identifier (20) comes within the range of a signal (S) transmitted by the vehicle (10), evaluating said distance (d) by means of a measurement, by the identifier (20), of the strength of said transmitted signal (S). An associated electronic unit and identifier are also described.

    Abstract: A compact head-up display for a vehicle includes: an image generator that displays an image on a display surface, and a semi-reflecting optical element, arranged at a distance from the image generator, that forms, on a first side of the optical element, a virtual image. The virtual image is visible from a viewing window on a second side of the optical element. The display includes an optical component that lengthens the optical path of the image passing from the image generator to the optical element. The optical component includes one entry face and one exit face, and a first reflecting face and a second reflecting face. The first reflecting face reflects the image from the entry face toward the second reflecting face. The second reflecting face reflects the image from the first reflecting face toward the exit face. The entry face is in contact with the display surface.

    Abstract: The invention relates to a head-up display system comprising: a processing module (1) designed to determine modified data representing a deformed image according to initial data representing an original image and deformation data defining an image deformation; a device (2) for generating a light beam representing the deformed image; and a projection device (3) designed to project the light beam in an adjustable direction towards a semi-transparent panel (4). The processing module (1) is designed to select the deformation data from a deformation table according to the adjustable direction.

    Abstract: The invention relates to a display (1) comprising: an image generation unit comprising at least one light emitter (23), a printed circuit support plate (22), on which said emitter (23) is mounted, and a light sensor (30) capable of delivering a signal representative of a light intensity received by same, the display (1) being adapted in such a way that the luminosity of an image generated by the image generation unit is controlled as a function of said signal. According to invention, the light sensor (30) is mounted on said printed circuit support plate (22).

    Abstract: The invention concerns a method (METH) for measuring a distance (R) separating a vehicle (V) and an identifier (I) for accessing and starting the vehicle (V), the vehicle (V) and the identifier (I) being synchronised, the method (METH) comprising: transmission (Em_TSvp), from the vehicle (V) to the identifier (I), of a first stream (TSvp) of N first sinusoidal signals (Svp) of identical amplitudes and of regularly spaced pe[1;N] respective frequencies fp—measurement (Mes_Dat) of phases (p) and amplitudes (ap), by the identifier (I), of signals of a first received image stream (TSvp′) corresponding to the first stream (TSvp) altered by the transmission—transmission (Tr_Dat) of the measured phases (p) and amplitudes (ap), from the identifier (I) to the vehicle (V)—transmission (Em_TSip), from the identifier (I) to the vehicle (V), of a second stream (TSip) identical to the first stream (TSvp)—construction (Cons_Sp) of a frequency spectrum (Sp) of the first image stream (TSvp′) and of a second image stream (TSip′) corresponding to the second stream (TS) altered by the transmission—an inverse Fourier transform (TFI_Sp), making it possible to obtain a time signature (Sg)—determination (Det_td) of an intermediate time (td) associated with a maximum of the time signature (Sg)—calculation (Cal_R) of the distance (R) from the intermediate time (td).
