However, in the vehicle horn sound generation system 100 as described above, when the driver presses the operation switch 120, a horn sound of a relatively large magnitude is always generated from the horn 130. As the horn sounds relatively small when the day is noisy or when the weather is relatively low in humidity, the horn is not a big problem. If the humidity is cloudy days, the horn sounds relatively loud, so there is a problem that the noise acts.

Accordingly, the present invention is to select the type of horn sound according to the current driving conditions of the vehicle affecting the horn sound, such as vehicle speed, day and night illumination, humidity, etc. and at the same time adjust the low, long and short, the size of the selected high horn sound It is based on the task to provide a horn sound control system for a vehicle that can achieve an optimal horn sound generation effect on the current driving conditions and at the same time reduce noise pollution.

In general, the horn of a vehicle sounds relatively low when the vehicle is traveling at high speeds along the road, during the daytime, when the humidity is relatively low, when the ambient temperature is high, or when the ambient air pressure is high, and the vehicle slows down the alleys. Since it sounds relatively loud in a cloudy day when driving, at night, or relatively high in humidity, or in low ambient temperature, or in high ambient pressure, the sensor unit 30 may include a speed sensor, an illuminance sensor, and a humidity level. It is preferably formed of a combination of one or more of a sensor, a temperature sensor, and a barometric pressure sensor.

The measured values of the sensor unit 30 are input to the control unit 40, which calculates the measured values input from the sensor unit 30 through a predetermined program to generate the horn sound generated by the home 80. By selecting the type and providing the optimum high and low control signals, long and short control signals, and magnitude control signals for the selected horn sound to the respective control units 50, 60, and 70, the control units 50, 60, and 70 are provided to the control signal. Operate accordingly.

The control unit 40 preferably includes sound storage means for storing various types of horn signals for selection of the type of horn sound, whereby the control unit 40 calculates the measured values input from the sensor unit 30. Therefore, among the various horn sounds stored in the sound storage means, one horn sound suitable for the current driving condition is selected. The horn sounds stored in the sound storage means are preferably normal claw sounds, frog sounds, birds sounds, human voices, and specific melodies.

The high and low control signal output by the control unit 40 is input to the high and low control unit 50, the high and low control unit 50 is a horn so that a horn sound having a high and low corresponding to the high and low control signal input from the control unit 40 is generated. By driving 80, FIG. 3 shows a configuration diagram of the height adjustment unit 50. As shown in FIG.

As shown in FIG. 3, the high and low adjustment unit 50 is composed of a variable resistor for changing the magnitude of the current provided to the horn 80, and accordingly, the horn 80 according to the high and low control signal input from the control unit 40. It is preferable that the horn 80 is configured to drive the horn 80 so that a horn sound having a height corresponding to the control signal is generated by changing the magnitude of the current provided to the control signal.
