JPH01195156A - Automatic announce circuit for automobile - Google Patents

Abstract

PURPOSE:To give a sound warning to a driver and to secure safety by freely operating a designated warning sound generating circuit by operation of an automatic switch control circuit connected to a door switch, a timer, a speed meter and so on. CONSTITUTION:An automatic switch control circuit 1 is connected to a door switch, a timer, a speed meter and so on, and a switch 2 of a sound generating circuit 4 can be operated by operation of the circuit. Warnings by designated sounds such as a warning for preventing a driver from forgetting to pull out a key according to a door switch, a warning for preventing a doze at every designated time using a timer, a warning for speed over according to a speed meter and so on are given so as to secure safety.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Description of the field to which the invention pertains The present invention relates to an automatic automobile announcement circuit for emitting audio information to a driver of an automobile.

(2) Description of conventional technology One of the conventional heel technologies includes, for example, bus stop guidance. This information is not for the driver but for the passengers, and is operated by the driver's manual switch.

Another example is ``Answer Wan-Wan,'' which detects a person's speaking voice and turns on a switch, causing a stuffed dog to respond. However, conventional systems that automatically generate a warning sound to the driver of a car have had drawbacks such as forgetting to pull out the bell and being unable to open the door.

(3) Purpose of the Invention The present invention is characterized by automatically issuing a warning so that the driver does not forget to take out the car key or fall asleep while driving, thereby improving driver safety.

The drawings will be explained in detail below.

(4) Description of structure and operation of the invention FIG. 1 shows an embodiment of the invention, in which l is an automatic switch control circuit, 2 is a switch, 3 is a power supply, and 4 is a sound generation circuit.

The automatic switch control circuit 1 generates a control signal for preventing forgetting to remove the key, a control signal for preventing drowsy driving +h, etc. according to the type of warning, and outputs them to the switch 2. Switch 2 receives the W115 signal, closes the switch circuit, and connects power source 3.
is connected to the audio generation circuit 4.

Next, embodiments of each part will be described in detail.

One possible embodiment of the automatic switch control circuit 1 for preventing forgetting to remove the key is to use a car door, for example. One example of this method is to set a button switch (equivalent to switch 2) between the driver's door and the vehicle body.
When the door is opened, the button switch is activated and the power supply 3 is turned on.
and the audio generating circuit 4 are connected. It is clear that there are two ways to use the power source 3: using an automobile battery or using another battery. Another example of the automatic switch control circuit l is a method in which an optical semiconductor is used like an automatic door opener used in department stores, etc., and the switch is activated by sensing when the driver gets out of the car. can also be easily inferred.

One embodiment of the automatic switch control circuit 1 for preventing drowsy driving includes a method in which a timer is set and the switch 2 is activated at predetermined intervals.

In addition, when the present invention is used to prevent speed overs, as an embodiment of the eye movement switch control circuit l, a bell would ring in the past when speeds were over;
It is possible to use a good luck signal for ringing this bell.

Next, the sound generation circuit 4 will be described. Sound generation circuit 4
Examples include a method using a tape recorder,
There is a method of storing voice data in a read-only memory and using voice synthesis technology or the like to read the voice data.

The content of the generated sound may be stored in accordance with the purpose of use. Of course, it is obvious that music can also be used.

In the above description, explanations have been made independently depending on the purpose of use, but it is clear that the purpose of use can be shared.

Further, in the above description, the automatic announcement circuit for a vehicle has been described, but it is clear that the present invention includes a circuit of a vehicle that includes this function.

(5) Description of Effects As explained above, according to the present invention, various warnings are automatically issued without the driver directly turning on a switch, so there is an advantage that the safety of the driver can be improved.
