    • PURPOSE: A navigation device is provided to reduce the possibility of a pile-up accident generation in the situation in which the view clarity of the front is difficult in a high frequency fogging area. CONSTITUTION: A navigation device comprises a controller(20) and communication module(30). The control unit decides whether or not a vehicle rapidly decelerates or suddenly stops by using GPS signals at first and second point of time. The control unit outputs control signals according to a decision that the front vehicle rapidly decelerates or suddenly stops. The communication module outputs an attention signal to outside according to whether or not the control signals output by the control unit are received.
    • 目的:提供一种导航装置,以便在高频起雾区域难以观察前方的视野清晰度的情况下减少堆积事故产生的可能性。 构成:导航装置包括控制器(20)和通信模块(30)。 控制单元通过在第一和第二时间点使用GPS信号来判定车辆是否快速减速或突然停止。 控制单元根据前方车辆快速减速或突然停止的判定输出控制信号。 通信模块根据控制单元输出的控制信号是否接收到外部的注意信号。

    • 본발명은교차로의횡단보도교통안전장치에관한것으로서, 횡단보도의입구로무단진입하는보행자를감지하여그 데이터를제어모듈(40)에제공하는보행자감지모듈(20); 횡단보도에설치된보행자신호등의신호를판독하여그 데이터를제어모듈(40)에제공하는신호모듈(30); 보행자감지모듈(20)과신호모듈(30)에서각각제공되는데이터를분석하여보행자신호등이정지신호일때, 횡단보도로무단진입하는보행자를판독하고, 무단진입이판독되면알림모듈(50) 제어신호를출력하는제어모듈(40); 제어모듈(40)에서제공되는제어신호에따라알림신호를출력하는알림모듈(50); 을포함한다. 본발명에따르면, 보행자감지모듈(20)의설치수를줄임으로써, 설치비용이절감될뿐만아니라, 보행자감지모듈(20)로인한보행자의보행간섭및 보행자추돌위험을줄일수 있으며, 횡단보도보행자신호등이보행신호일때 횡단보도쪽으로진입하는차량을감지하여횡단보도를통행하는보행자에게위험을알려줄수 있도록함으로써, 보행자의보행안전을더욱향상시킬수 있는효과가있다.
