Abstract

The vehicular navigation equipment includes the following parts: a GPS receiver, an I / O interface device connected to the GPS receiver for the I / O of the position information, a display device, a loudspeaker, a speed sensor, phonetic recognizer, and a controller connected to the I / O interface device to control different parts and regulate the volume of phonetic service automatically based on the speed sensor measured varying vehicle speed. It monitors the speed of the vehicle and regulates the volume of phonetic service automatically based on the varying vehicle speed. In this way, relevant vehicle running information may be heard clearly even in high speed running. In addition, it is connected to various audio and video devices inside the vehicle, has the function as vehicular information service system and can regulate the sound strength signal of the driver automatically so as to regulate the volume of output audio signal.

Description

technical field [0001] The invention relates to a vehicle navigation device. Specifically, it relates to a vehicle navigation device and a working method thereof that automatically adjust the volume output by a navigation device connected to a vehicle information service system (telematics) according to changes in vehicle speed. Background technique [0002] A car navigation device is a device that is installed on a vehicle, uses the geographic location information output by a GPS (globalpositioning system) receiver, decodes it, and then transmits it to the driver to navigate the vehicle. [0003] That is, the car navigation device prompts the driver for a specific route. Match the map data stored in memory such as CD-ROM, ROM or RAM, and GPS data to identify the current position of the vehicle. Then, the distance is calculated, and the driver is prompted according to the calculated route from the current position to the destination. [0004] figure 1 It is a schematic d...
