Abstract

<P>PROBLEM TO BE SOLVED: To solve such a problem that most conventional warning sound generators generate a monotonous sound or music and a generator for generating a more effective warning sound is desired. <P>SOLUTION: A traveling sound generator has a traveling speed detecting device or an acceleration detecting device. Accordingly, the traveling sound generator can generate an effective warning sound in accordance with a traveling state by changing the warning sound according to traveling speed or acceleration. During traveling at a certain speed, negative effects in which a monotonous sound is continuously produced is stronger than positive effects in which a driver recognizes the acceleration of a vehicle and enjoys the acceleration feel. Thus, the warning sound can be stopped when the condition where the certain speed is continued for a certain time is satisfied. <P>COPYRIGHT: (C)2011,JPO&INPIT

The travel sound generator is required for each of the three parts, a detection unit composed of a travel speed detection device or an acceleration detection device, a processing unit composed of a central processing unit for controlling the entire travel sound generation device, a sound generation unit composed of a warning sound generation device It consists of four departments of the power supply section that sends a large amount of power, and all are mounted on the vehicle.
Each detection device sends the detection result as an electrical signal to the connected central processing unit. The warning sound generator converts the output from the connected central processing unit into a sound signal by vibrating a speaker or buzzer that incorporates the output.
The central processing unit can receive a result detected by each detection device as an electrical signal, and can generate various warning sounds from the warning sound generation device based on a predetermined program.

請求項1の発明は、走行速度検出装置を有する走行音発生装置である。
警告音は、本来的に車両の接近を周囲に警告するためのものであるため、接近スピードが速いほど警告音の音量を大きくしたり、周波数を高めたりすることにより、周囲の者に警戒感を強く感じさせることができる。
The invention of claim 1 is a traveling sound generator having a traveling speed detecting device.
The warning sound is intended primarily to alert the vehicle to the surroundings, so the higher the approach speed, the greater the warning sound volume and the higher the frequency. Can be felt strongly.

実施例1では、車両に既設の走行速度計から信号を読み取り可能な走行速度検出装置を車両に設置する。
中央処理装置には警告音発生装置が接続され、走行速度検出装置から入力される走行速度が増すほど警告音発生装置に内蔵されるスピーカーから発生する警告音の音量が大きくなるようにした。
In the first embodiment, a travel speed detection device that can read a signal from a travel speed meter already installed in the vehicle is installed in the vehicle.
A warning sound generating device is connected to the central processing unit so that the volume of the warning sound generated from the speaker built in the warning sound generating device increases as the traveling speed input from the traveling speed detecting device increases.

請求項2の発明は、加速度検出装置を有する走行音発生装置である。
警告音は、本来的に車両の接近を周囲に警告するためのものであるが、一方で従来のエンジンを動力源とする車両のように、エンジン回転音のような加速感を音により表現することで、運転者に車両の加速の程度を認識させたり、加速感自体を楽しめるように演出することができる。
The invention of claim 2 is a traveling sound generating device having an acceleration detecting device.
The warning sound is intended primarily to warn the approach of the vehicle to the surroundings, but on the other hand, it expresses an acceleration feeling like an engine rotation sound by sound like a vehicle using a conventional engine as a power source. Thus, the driver can be made aware of the degree of acceleration of the vehicle, and can be produced to enjoy the feeling of acceleration itself.

実施例2では、モーターのみを動力源とする電動バイクにおいて、モーターに対する入力電力を読み取り可能な加速度検出装置を車両に設置する。

本発明は以下に示すように変更して実施することも可能である。
・一定時間一定速度の条件を満たした場合には、自動的に警告音を止まるように変更すること。これは、一定速度で走行する場合は、運転者に車両の加速の程度を認識させたり、加速感自体を楽しめるように演出する長所よりも、単調な音が連続的に鳴っていることの弊害の方が高くなるため、警告音を止める機能を付加するものである。
・警告音の音量と周波数が同時に変化するように変更すること。
・走行音発生装置の電源を車両のバッテリーから供給するように変更すること。
・現実のエンジン音を録音装置に記録した音を警告音として利用すること。
The present invention can also be implemented with modifications as shown below.
・ If the condition of constant speed is satisfied for a certain period of time, the warning sound should be automatically changed to stop. This is due to the fact that when driving at a constant speed, the monotonous sound is continuously sounding rather than the advantage of directing the driver to recognize the degree of acceleration of the vehicle or enjoying the feeling of acceleration itself. Therefore, a function to stop the warning sound is added.
・ Change so that the volume and frequency of the warning sound change simultaneously.
・ Change the power supply of the running sound generator to be supplied from the vehicle battery.
-Use the sound of the actual engine sound recorded on the recording device as the warning sound.
