Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voice alarm system for a vehicle, and more particularly to an improvement of a voice alarm system for a vehicle, which can be mounted on a vehicle and various voice messages are audibly voiced according to a driver's operation. .

[0002]

2. Description of the Related Art With the progress of motorization in recent years, traffic accidents due to automobiles have been increasing year by year, which has become a major social problem. Along with various measures taken by related ministries and agencies, it is a very important issue to raise awareness and attention to safe driving to the driver of a car. This is also clear from the fact that the number of traffic accidents due to psychological factors such as the driver's carelessness, beliefs, or lack of caution during driving is increasing.

Further, various information transmission means of automobiles display the remaining amount of gasoline, speed display, time, etc. by a meter,
It is configured to be able to display an alarm for some of these items. Further, the voice is uttered only when the speed exceeds the specified speed, and the visual display is mainly performed, so that the driver must monitor various meters in addition to the driving visual field. In this way, it is extremely dangerous for the driver to visually check various instruments while driving,
There has been a demand for a method of recognizing the dangerous state of each device mounted on the vehicle other than visual inspection. Further, there is also a problem that the operator forgets to operate various instruments due to the driver's carelessness.

[0004]

Therefore, conventionally, Japanese Patent Publication No. 55-6530 and Japanese Patent Publication No. 1-22677 have been proposed.
JP-A-55-110636 or JP-A-55-
