Description
技术领域
本发明涉及一种导航辅助装置,并且更具体地涉及用于车辆特别是机动车辆的夜间道路导航辅助。
背景技术
已知称为“夜视”的***,其使用用于拍摄车辆前方场景的比人眼更敏感的照相机并在屏幕上为驾驶员显现出该图像。这些***旨在可以在夜间或能见度降低(雨、雪、雾……)的条件下驾驶,其能见度高于前照灯所提供的能见度,同时避免眩光。这些***使得驾驶员能够接触有关路面场景的信息,该路面场景是该驾驶员未觉察到或即使看路也不能很好觉察到的路面场景,然而当该驾驶员看屏幕时,其可能看到路面场景,该路面场景例如为在人行道上有行人或远处的道路轮廓。
这种***的缺点在于,一旦启动,该***就会持续显示图像。对驾驶员而言,这些图像分散注意力或造成不便。停止该显示的唯一方法就是停用***。然而,在这种情况下,驾驶员不再受益于***的警报。
例如,法国专利申请FR2902381公开了一种夜视***,其实现:通过图像形成装置检测道路场景的区域的位置,形成与所定位的道路场景的区域相对应的合成图像,并且将由图像形成装置采集的图像和该合成图像合并,这种合并的结果在车辆的屏幕上显示。
发明内容
因此,本发明旨在提出一种夜视装置,其允许不打扰驾驶员并在检测到危险时准确有效地提醒驾驶员。
为此目的,本发明更具体地提出一种车辆的夜间驾驶辅助装置,其包括至少一个显示器(23)和夜视***(20),该夜视***能够在黑暗的条件下拍摄图像并将这些图像传输到显示器(23),该显示器(23)能够显示图形页面(31),该图像页面包括第一区域(31.1)和第二区域(31.2),该第二区域设置在第一区域(31.1)旁边,该显示器(23)包括第一显示模式,在第一显示模式中,该第一区域(31.1)包括该车辆的运行信息,其特征在于,响应于接收到来自夜视***(20)的警报信号,该显示器(23)能够在第二区域(31.2)中显示来自夜视***(20)的图像。
本发明允许在通过夜视***输出警报时准时显示来自该***的图像。因此,当没有输出警报时,这些图像不会干扰驾驶员。这些图像在预定区域(第二区域)中显示,使得车辆的运行信息(在第一区域中示出)保持可见。维持对这些信息的显示允许不会毫无必要地干扰对这些显示保持视觉参考的驾驶员。
最后,图像的显示使得驾驶员可以特别精确地观察到夜视***所发出的警报的性质。
有利地,夜视***能够输出一级警报和二级警报,该一级警报指出的危险比二级警报高,在第一显示模式中,该显示器配置成仅响应于接收到与一级警报相对应的警报信号而在第二区域中显示来自夜视***的图像。
这样,驾驶员不会被重要程度较低的警报干扰。来自夜视***的图像仅在输出一级警报时显示。
有利地,在第一显示模式中,该显示器配置成仅在接收该警报信号所持续的期间准时显示来自夜视***的图像。
这样,当与警报有关的危险消除时,驾驶员不受到来自夜视***的图像的干扰。
有利地,显示器包括用于重新调整和/或重新定位来自夜视***的图像的装置,在第一显示模式中,在第二区域所显示的图像被重新定位或重新调整。
该特征使得可以在减小的区域中显示来自夜视***的图像,同时维持关注与警报相关的危险的高信息水平。
有利地,显示器包括第二显示模式,在第二显示模式中,显示器在第一区域持续显示来自夜视***的图像。
第二显示模式允许驾驶员在其希望看到图像时获得来自夜视***的图像。
有利地,响应于接收到用户的命令,显示器能够从第一显示模式转换到第二显示模式,反之亦然。
有利地,显示器能够在第一显示模式中显示指示器,其指示夜视***是否启动。
由于在缺乏持续显示的图像的情况下,当没有正在进行的警报时,驾驶员没有其他方法了解***是否启动,因此,指示器允许向驾驶员指出夜视***是否启动。
有利地,在第一显示模式中,第一区域包括车辆的运行数据或引导数据。
有利地,第一区域显示在显示器的中间部分。
有利地,图形页面还包括第三区域,该第二区域和第三区域位于第一区域的两侧。
本发明还涉及一种车辆,其特征在于,该车辆包括根据本发明的夜间驾驶辅助装置。
附图说明
通过研究下面的详细描述和附图,本发明的其他特征和优点将显现,在附图中:
-图1示出了根据本发明的机动车辆仪表板;
-图2示出了根据本发明的***的功能示意图;
-图3a示出了根据本发明的第一显示模式;
-图3b示出了当夜视***发出警报时的第一显示模式;
-图4示出了根据本发明的第二显示模式。
具体实施方式
附图不仅可用于补充本发明,如有必要时,还有助于对本发明进行限定。
在图1的附图中,示出了根据本发明的机动车辆仪表板,其配备有两个屏幕和夜间道路导航***。第一屏幕1是GPS(“Global Positioning System(全球定位***)”的首字母缩合词)类型的常规道路导航***,其以本身已知的方式显示地图以及路线、视角、颜色和信息。第二屏幕2是称为“夜视”的***的屏幕。在屏幕2上,结果类似于标示为Z的道路场景的相当详细的黑白视频图像。
根据本发明的夜视***的架构通过图2的功能示意图示出。
***20包括图像采集装置21、计算机22,该计算机22与至少一个显示器23通信。
图像采集装置21由安装在车辆前部的至少一个夜视摄像机构成。
根据第一种技术,离散地集成在车辆前部处的摄像机接收由道路反射的红外投影仪图像。在第二种技术中,摄像机接收来自场景的元素的热辐射。
这些图像通过例如LVDS类型的第一视频链路24传输到计算机22,以进行处理。了解到,LVDS(“Low Voltage Differential Signaling(低压差分信令)”的首字母缩合词)链路允许连接两个设备并传输视频数据和非视频数据。
根据本发明的计算机22包括用于处理图像的模块(电子模块),该图像来自采集装置21。
处理过的图像通过例如LVDS类型的第二视频链路25传输到显示器23。
已知地,计算机22包括行人检测模块。在检测到骑自行车的人或动物时,检测模块还在车辆的CAN总线26上和/或在第二视频链路25上向显示器23输出警报信号。
计算机22能够输出一级警报和二级警报,一级警报指出的风险比二级警报更高。一级警报例如对应于在道路上检测到行人或动物。二级警报例如对应于在人行道上检测到行人或动物。
有利地,因此可以突出显示在道路或行人道上检测到的行人或动物,例如通过使它们以颜色(例如红或黄)闪烁和/或通过显示图标来突出显示。
显示器23可以是图1的附图中的第二屏幕2,或者是根据另一实施例的另一图像投影***。因此,显示器23可以例如是LCD(“Liquid Cristal Display(液晶显示器)”的首字母缩合词)类型的传统屏幕,或者HUD(“Head Up Display(平视显示器)”的首字母缩合词)类型的图像投影***。
显示器23包括至少两个不同的显示模式。两个显示模式中的每一个包括位于屏幕中间部分的第一显示区域31.1。第二显示区域31.2和第三显示区域31.3分别设置在该第一显示区域31.1的右左两侧。显示器23例如包括下述模式中的至少一个。
图3a示出了第一显示模式31,其中第一显示区域31.1包括车辆的运行数据。在示例中,这是车辆速度的指示,该车辆速度的值为90km/h。
第二显示区域31.2包括引导指令。
第三显示区域31.2也包括车辆速度的指示,然而该指示呈现仪表的形式。
显示区域31.1用于持续显示信息。
第二区域31.2和第三区域31.3能够显示一次性信息(例如导航指令或警报)。
图3b示出了当显示器23接收来自夜视***的警报时的第一显示模式31。
该第一区域和第三区域与图3a相同。相反地,第二区域显示来自摄像机21的图像以及图标。
第二显示模式31在图3a中示出,其中第一显示区域31.1包括来自摄像机21的图像,并且其中第二显示区域31.2和第三显示区域31.3包括车辆的运行数据。在该示例中,第二区域31.2包括级别的指示,该级别的值约为3.5。
第三区域31.3包括车辆的速度的指示,该速度的值为90km/h。
在第一显示区域31.1中,来自摄像机21的图像包括检测到动物的指示(为彩色多边形的形式)。
