Abstract

본 발명은 차량용 교통안내 시스템의 음성 출력장치에 관한 것으로, 집음기를 통하여 차량 내부의 소음 정보를 마이크로 프로세서에 인식하여 음성 안내되는 소리의 증폭 상태를 조절하여 출력되도록 하되, 사용자가 키이 입력부의 선택 키이를 통하여 지도의 디스플레이 모드를 선택하면, 이를 입력받은 마이크로 프로세서에서 표시부를 통하여 차량의 출발 위치와 목적지 위치를 표시하여 사용자가 업/다운 키이 및 입력 키이를 통하여 출발지와 목적지의 지명을 입력시키도록 하고, 사용자가 가고자하는 목적지를 포함하는 지도를 롬에서 읽어내어 디스플레이하는 중에, 차량이 교차로 등의 위치에 가까와져서 운전자에게 음성안내가 필요한 경우에는 차량의 내부 소음을 측정하면서 레벨을 결정하고, 상기 소음 레벨에 따라 CD-ROM 오디오에서 출력되는 음성의 볼륨을 자동으로 선택하여 내부의 소음에서 안내를 잘 들을 수 있도록 함으로써 운전자가 안내를 적절한 음성으로 들을 수 있도록 한 것이다.The present invention relates to a voice output device of a traffic guide system for a vehicle, and recognizes the noise information inside the vehicle to a microprocessor through a sound collector so as to adjust the amplification state of the voice guided sound and output the same, wherein the user selects a key input unit. When the display mode of the map is selected through this, the microprocessor which receives the map displays the starting position and the destination position of the vehicle through the display unit so that the user can input the place name of the starting point and the destination through the up / down keys and the input keys. When reading and displaying a map including a destination to which the user wants to go, when the vehicle is approaching a location such as an intersection, and the driver needs voice guidance, the level is determined while measuring the internal noise of the vehicle. Depending on the level, the output may be from CD-ROM audio. Automatically selects the volume of the voice so that the operator can hear the guidance well from the noise inside, so that the driver can hear the guidance with the proper voice.

Claims

When the user selects the display mode of the map through the selection key of the key input unit, the microprocessor receiving the input displays the starting position and the destination position of the vehicle, and the user inputs the place name of the starting point and the destination through the up / down keys and the input key. A voice output device of a vehicular traffic guidance system that displays a map including a destination and reads it from a ROM, and a sound collector for collecting and amplifying the noise inside the vehicle, and to what extent the noise is? Vehicle level control comprising a level detector for measuring and transmitting to the microprocessor, and the electronic volume for controlling the level of data of the voice guidance according to the progress of the vehicle output from the CD-ROM audio by the control of the microprocessor Voice output of guidance system.

Recognizing that voice guidance is necessary at an intersection or the like while comparing the map data with the current vehicle location, and checking the noise level inside the vehicle via the level detector collected through the sound collector; Drives CD-ROM audio to output voice guidance information such as “How to Enter Intersection” or “U-Turn Position”, and outputs a control signal to the electronic volume so that it can be adjusted to a volume that can be easily heard inside the vehicle. Voice output device of a traffic guidance system for a vehicle, characterized in that performed by the steps.
