Definitions
- the present invention relates to a display device for a motor vehicle, and in particular a device adapted to reflect on the windshield of the vehicle information in the form of geometric images.
- the driver assistance systems broadcast, when they detect an anomaly, a message to the driver in order to elicit a reaction from him.
- These systems are for example implemented for the prevention of lane departure or to signal the proximity of another vehicle.
- alert messages There are different types of alert messages. Broadcasting a visual message in the dashboard is not appropriate because the message is unlikely to be detected. It is also known to use audible messages, which may be appropriate in case of danger, and therefore if a quick reaction is expected. Nevertheless, the sound messages are unintelligible and often embarrassing.
- the present invention aims to remedy these disadvantages.
- the invention thus relates to a display device for a motor vehicle.
- the device according to the invention comprises:
- a light source capable of emitting light signals
- a light guide able to guide the light signals through a plurality of openings of the guide, so as to reflect, on a surface of the vehicle, a plurality of bright images.
- the device may further comprise a diffuser, able to diffuse the light signals coming from the light guide.
- the diffusing material may be of translucent material.
- the surface of the vehicle on which the bright images are reflected may be the windshield of the vehicle.
- the light source may include a plurality of light emitters.
- the openings of the light guide may be of geometric, alphanumeric, or pictogram-like section.
- the light source can be arranged on a printed circuit.
- the printed circuit can be connected to a power supply.
- the printed circuit may be connected to control means of the light source.
- the invention also relates to a motor vehicle comprising a device described above.
- FIG. 1 illustrates a device according to the invention in perspective. exploded.
- the display device 1 as illustrated in FIG. 1, comprises an electronic card 2, a light guide 3 and a diffuser 4.
- the electronic card 2 comprises light emitters of the electroluminescent diode type 5.
- the electronic card 2 is connected to a power supply via a link 21, and to an electronic network of the vehicle, typically a computer, by means of a link 22.
- the vehicle's electronic network transmits the order to trigger the appropriate animation at the appropriate time.
- the diodes 5, or any other appropriate light source send light signals towards the light guide 3.
- the light guide 3 comprises openings 31, so as to guide the light signals and to form light images 6 of geometric shapes determined by the shape of the openings 31.
- the openings 31 of the light guide 3 can for example be of geometric section such as circular, rectangular, square, trapezoidal, arc-shaped, or in the form of a dotted line, or according to other examples of alphanumeric section or the shape of a pictogram.
- the light images formed in the light guide 3 are then directed towards the diffuser 4.
- Luminous images 6 are thus reflected on a windshield 7.
- the diffuser 4 makes it possible to broadcast the light signals coming from the light guide 3.
- the diffusing 4 thus makes it possible to burst the luminous point coming from a diode 5 and to distribute the luminosity over the whole of the geometrical shape 6.
- the windshield 7 is not always treated, it is possible that a double image is created.
- the diffuser 4 allows to create a blur, so that the two images are mixed and thus a single image is perceived by the driver.
- the blurring is adapted to a peripheral vision, because the eye is thus less tempted to be attracted by this image and to accommodate at its focal length.
- the driver's gaze can remain on the road while he captures the transmitted message or messages.
- the shape of the images 6 makes it possible to broadcast several images simultaneously when needed.
- the diffuser 4 may be chosen from any translucent material.
- the degree of translucency can be adjusted according to the desired blur / brightness compromise.
- the device according to the invention can be positioned at any point of the dashboard of the vehicle, and not only facing the driver.
- the reflection can be positioned on the transparent part of the windshield, but also on the windshield enamelling line.
- the image formed is clear and it is not necessary to create a blur as in the case where the overhead projection is performed on the transparent portion of the windshield.
- This projection on the blade has the advantage of not having to treat the windshield, as is the case when using a diffuser.
