Abstract

This invention relates to car guide system sound output control device, which comprises the following parts: multi-sound output device for sound signals with different states; GPS receiving device to receive GPS signals; mobile communication device to receive and send mobile communication signals; amplifier for each sound signals from the above devices; control device to control the above devices more than one sounds signals.

Description

(1) Technical field [0001] The present invention relates to vehicle guidance systems. In particular, it refers to a sound output control device and method for a vehicle guidance system that can automatically adjust the amplitude of sound signals when multiple sound signals are output at the same time. (2) Background technology [0002] The development of industry and technology provides modern people with fast information and various technologies. The vehicle guidance system is also a product that emerges at the historic moment with the development of this type of technology. In particular, with the continuous increase of vehicles, the complexity of transportation and the increase of logistics costs are causing economic and time losses. Therefore, in order to prevent the generation of such economic losses, it is necessary to find effective ways to control traffic conditions. One of these is the use of vehicle guidance systems. [0003] figure 1 It is a structural diagra...
