Description

用于机动车辆的显示装置Display device for motor vehicle

本发明涉及一种用于机动车辆的显示装置，并且尤其涉及一种能够将几何图像形式的信息反射到车辆挡风玻璃上的装置。The invention relates to a display device for a motor vehicle, and in particular to a device capable of reflecting information in the form of a geometric image onto the windshield of the vehicle.

当驾驶辅助系统检测到异常时，它们向驾驶员发出一个消息，用来提示他或她做出回应。例如使用这些系统来防止车道偏离、或用来向邻近的另一车辆发信号。When driver assistance systems detect anomalies, they send a message to the driver, prompting him or her to respond. These systems are used, for example, to prevent lane departures, or to signal the proximity of another vehicle.

已知多种不同类型的警告消息。在仪表板上发送可视消息是不适合的，因为消息几乎不会被注意到。还已知的是，在危险而因此期望得到快速回应的情况下，使用可听消息可能是合适的。然而，可听消息是难以理解的，并且经常是麻烦的。Several different types of warning messages are known. Sending visual messages on the dashboard is not suitable because the messages will hardly be noticed. It is also known that in situations of danger and thus a quick response is desired, the use of audible messages may be appropriate. However, audible messages are incomprehensible and often bothersome.

文件US 2009/0231116描述了一种装置，该装置包括被放置在车辆仪表板上的二极管，用来生成点和线形式的映像。然而，这些形状不能充分告知消息的内容。驾驶员知道他或她必须回应，但不知道为何。Document US 2009/0231116 describes a device comprising diodes placed on the dashboard of a vehicle to generate images in the form of points and lines. However, these shapes do not adequately inform the content of the message. The driver knows he or she has to respond, but not why.

本发明的一个目的是克服这些缺点。An object of the present invention is to overcome these disadvantages.

具体地讲，本发明提供了一种用于机动车辆的显示装置，该显示装置允许向驾驶员可理解地传输消息。In particular, the invention provides a display device for a motor vehicle which allows the intelligible transmission of messages to the driver.

因而，本发明涉及一种用于机动车辆的显示装置。Thus, the invention relates to a display device for a motor vehicle.

根据本发明的装置包括：The device according to the invention comprises:

-一个光源，该光源能够发出光信号，以及- a light source capable of emitting a light signal, and

-一个光引导件，该光引导件能够通过该引导件的多个开口来对光信号进行引导，以便将多个光图像反射到该车辆的一个表面上。- A light guide capable of directing light signals through openings of the guide to reflect light images onto a surface of the vehicle.

因此，借助该光引导件的存在，可能形成多个光图像，其几何形状由这些开口的形状来确定，这使得可能形成一个对于驾驶员来说是清楚而且信息量丰富的消息。Thus, by virtue of the presence of the light guide, it is possible to form light images, the geometry of which is determined by the shape of the openings, which makes it possible to form a message which is clear and informative to the driver.

此外，该装置可以包括一个扩散器，该扩散器能够使来自该光引导件的这些光信号扩散。Furthermore, the device may comprise a diffuser capable of diffusing the optical signals from the light guide.

该扩散器可以由半透明材料制成。The diffuser can be made of a translucent material.

光图像被反射至其上的车辆表面可以是车辆的挡风玻璃。The vehicle surface onto which the light image is reflected may be the vehicle's windshield.

该光源可以包括多个光发射器。The light source may include a plurality of light emitters.

该光引导件的这些开口可以具有一种几何或字母数字截面、或者一种象形图形状。The openings of the light guide may have a geometric or alphanumeric cross-section, or a pictographic shape.

该光源可以被安排在一个印刷电路上。The light source may be arranged on a printed circuit.

该印刷电路可以与一个电源相连接。The printed circuit can be connected to a power source.

该印刷电路可以与该光源的控制器具相连接。The printed circuit can be connected to the control means of the light source.

本发明还涉及一种包括如上所述的装置的机动车辆。The invention also relates to a motor vehicle comprising a device as described above.

在阅读以下说明时，本发明的其他特征和优点将变得更清楚，这些说明是以图示而非限制的方式并参照图1给出的，并且通过分解透视图展示了根据本发明的装置。Other characteristics and advantages of the invention will become clearer on reading the following description, which is given by way of illustration and not limitation and with reference to Figure 1, and shows the device according to the invention in an exploded perspective view .

如图1所展示的，根据本发明的显示装置1包括一个电子板2、一个光引导件3和一个扩散器4。As illustrated in FIG. 1 , a display device 1 according to the invention comprises an electronic board 2 , a light guide 3 and a diffuser 4 .

该电子板2包括发光二极管5类型的多个光发射器。该电子板2经由一个连接21而与一个电源相连接，并且借助一个连接22而与该车辆的电子网络(典型地是一个计算机)相连接。该车辆的电子网络发送指令来在正确的时间启动合适的动画。The electronic board 2 comprises a plurality of light emitters of the type light emitting diodes 5 . The electronic board 2 is connected via a connection 21 to a power source and via a connection 22 to the vehicle's electronic network, typically a computer. The vehicle's electronic network sends commands to initiate the appropriate animation at the correct time.

这些二极管5或任何其他合适的光源向该光引导件3发送光信号。该光引导件3包括多个开口31，以便引导这些光信号并形成光图像6，这些光图像具有由这些开口31的形状确定的几何形状。该光引导件3的这些开口31例如可以具有一种几何截面，如圆形的、长方形的、方形的、梯形的、圆弧形状的、或破折号的形式、或可替代地根据其他实例是一种字母数字截面或一种象形图的形状。The diodes 5 or any other suitable light source send light signals to the light guide 3 . The light guide 3 comprises openings 31 in order to guide the light signals and form light images 6 having a geometry determined by the shape of the openings 31 . The openings 31 of the light guide 3 may for example have a geometric cross-section, such as circular, rectangular, square, trapezoidal, arc-shaped, or dashed, or alternatively according to other examples a An alphanumeric cross section or a pictogram shape.

在该光引导件3中形成的这些光图像随后被发送到扩散器4。多个光图像6因而被反射到一个挡风玻璃7上。该扩散器4使之可能使来自于该光引导件3的这些光信号扩散。因而，该扩散器4使之可能使来自一个二极管5的光点扩大，并在整个几何形状6上分布亮度。此外，因为不会经常对该挡风玻璃7进行处理，可能会产生重像。该扩散器4使之可能产生模糊效果，从而使得这两个图像发生融合而驾驶员只会感知到一个单一图像。这种模糊与周边视觉相适配，因为眼睛由此会比较少地被这个图像吸引、并适应其焦距。因此，该驾驶员在他或她接收消息或发送消息时可将其视觉保持在道路上。事实上，这些图像6的形状使之可能在需要时同时发射多个图像。The light images formed in the light guide 3 are then sent to a diffuser 4 . Several light images 6 are thus reflected onto a windshield 7 . The diffuser 4 makes it possible to diffuse the optical signals coming from the light guide 3 . This diffuser 4 thus makes it possible to enlarge the spot of light from a diode 5 and to distribute the brightness over the entire geometry 6 . Also, since the windshield 7 is not often processed, ghosting may occur. This diffuser 4 makes it possible to produce a blurring effect so that the two images merge and the driver perceives only a single image. This blurring is compatible with peripheral vision, since the eye is thus less attracted to the image and adapts to its focus. Thus, the driver can keep his or her vision on the road while he or she is receiving or sending messages. In fact, the shape of these images 6 makes it possible to transmit several images simultaneously if required.

该扩散器4可选自于任何半透明材料。可根据所需的模糊/亮度折衷来对半透明的程度进行调整。The diffuser 4 can be selected from any translucent material. The degree of translucency can be adjusted according to the desired blur/brightness tradeoff.

根据本发明的装置可被定位在该车辆的仪表板的任何位置上，而不仅仅在驾驶员的前方。这种反射可被定位在挡风玻璃的透明部分上，但是还在该挡风玻璃的釉质线上。在这种情况下，因为是在该挡风玻璃的透明部分上进行反向投影，所形成的图像是清晰的，而不需要生成模糊。The device according to the invention can be positioned anywhere on the dashboard of the vehicle, not just in front of the driver. This reflection can be located on the transparent part of the windshield, but also on the enamel line of the windshield. In this case, since the back projection is on the transparent portion of the windshield, the resulting image is clear without blurring.

还可想到，将来自根据本发明的装置的图像投射在位于挡风玻璃下方的一个透明板或部分透明板上，因而使之可能在驾驶员的视线所及的可视区中对消息进行传输，无需他或她必须移动他或她的头部。这种在板上的投影具有的优点是，当使用扩散器时，不是必须对挡风玻璃进行处理。It is also conceivable to project the image from the device according to the invention on a transparent or partially transparent plate located under the windshield, thus making it possible to transmit the message in the visual zone within the driver's line of sight , without him or her having to move his or her head. This projection on the panel has the advantage that, when using a diffuser, no treatment of the windshield is necessary.
