However, in the case of a gasoline vehicle or a diesel vehicle, the pedestrian senses the presence of the vehicle traveling from the rear by the engine sound, so that it can be easily avoided to a safe place such as a road edge. On the other hand, It is difficult for pedestrians to detect the presence of a vehicle approaching from the rear, so that a case of accidental accident may occur. In addition, since the sound of the vehicle itself is quiet, there is no factor that can sense the speed feeling like the engine sound generated in a general gasoline vehicle or a diesel vehicle.

On the other hand, in general, the alarm sound of a vehicle is used when a driver or a pedestrian of another vehicle is noticed while the vehicle is running, or when the vehicle is traveling on an alley or a road blocked with a view of the right or left, To prevent accidents in advance. Generally, it is a device installed on a steering wheel to generate a constant sound. The conventional vehicle alarm sounder having such a structure is configured to output only a warning sound of a certain type, size, and sound regardless of the driving situation, the driver's taste, or the surrounding environment, There is a problem that intense notes are used.

Various devices have been developed to improve this point. However, the variable resistance value is changed according to the degree of pressure of the alarm sound, so that the output level of the sound is adjusted, the directivity of the sound is increased or decreased, The number of alarm sounds increases when the electric vehicle travels in a place where a lot of pedestrians move, such as a residential area, and thus there is a problem of causing unpleasant noise pollution to people living in the vicinity.

FIG. 6 is a schematic block diagram showing a magnetic part of a vehicular booming system according to a further embodiment of the present invention. FIG. 6 is a flowchart illustrating a control procedure of a vehicular booming system according to a preferred embodiment of the present invention.

(Hereinafter referred to as a "system") of the present invention includes a magnetic part 100, a control part 200, and an output speaker part 300.

The magnetic portion 100 may be disposed at a hinge portion through which the vehicle's accelerator 102 flows, as a means of initially generating an electrical signal. The magnet unit 100 includes a first magnetic magnet 110 and a second magnetic magnet 120. A second magnetic magnet 120 is attached to the lower end of the hinge end of the accelerator 102, A first magnetic magnet 110 electrically connected to the control unit 200 may be attached to a position opposite to the magnetic magnet 110. Each of the magnetic magnets 110 and 120 is accommodated in the housing and is spaced apart from each other with a different polarity. It may be preferable that the magnetic magnets are tightly fixed by bolting. 6 may be attached to the side of the accelerator 102 as shown in FIG. 6, but it is not intended to be limited to any one location, and may be attached at various locations within the scope of the present invention Of course.

The magnetic magnets 110 and 120 are accommodated in the housing, and a resistance regulating member 112 in the form of a film may be disposed on the housing. The resistance adjusting member 112 may have a thickness of 2 to 8 mm, and the metal and the non-metal may be mixed at a predetermined ratio. More specifically, the resistance controlling member 112 may be formed by mixing a ferromagnetic material, a nonmagnetic material, a synthetic resin, and a mineral material at a predetermined ratio.

The resistance adjusting member 112 disposed on the upper surface of the magnetic magnets 110 and 120 may be formed such that when the magnetic magnets 110 and 120 face each other and are spaced apart from each other by a predetermined distance The magnetic lines of force are activated and the current is cut off and the actuating signal is not transmitted. On the other hand, when the magnetic magnets 110 and 120 are separated from each other by a physical force, the magnetic force lines are inactivated and power can be cleared. That is, if the magnetic magnets 110 and 120 face each other, the current is blocked, and if the magnetic magnets 110 and 120 move away, current flow can be activated.

In addition, the magnets 110 and 120 may vary the magnitude of the output volume according to the amount of electric current to be supplied. 1, each of the magnetic magnets 110 and 120 gradually moves away from each other as it presses the accelerator 102. By adjusting the strength of the resistance by the resistance adjusting member 112 as described above, 110, and 120 are distant from each other, the output sound is amplified.

For example, when the first magnetic magnet 110 and the second magnetic magnet 120 are disposed to face each other, the magnetic lines of force are very activated to interfere with current conduction, thereby disconnecting the electrical connection to the overall system. When the first magnetic magnet 110 and the second magnetic magnet 120 are horizontally or vertically distant, the magnetic field lines gradually become inactive and accept the electric current. Accordingly, the electrical connection to the system is activated as the electric current is supplied to convert the electrical signal from the central control unit 200 to the output speaker 300 into sound waves, thereby outputting the exhaust sound. The resistances of the magnetic magnets 110 and 120 gradually decrease as the magnetic magnets 110 and 120 are moved away from each other due to the resistance adjusting member 112 disposed on the magnetic magnets 110 and 120 so that the vibration of the exciter 102 is amplified It can be reduced.

In the following, changes in the resistance values of the two magnetic magnets 110 will be described in detail.

3, when the voltage applied to the resistance adjusting member 112 becomes V0, the resistance value of the resistance changing element 112 is changed from the resistance value R L in the low resistance state of the resistance adjusting member 112 to the high load low state Lt; RTI ID = 0.0 > R0. ≪ / RTI > In other words, when the voltage of V0 is applied to the resistance adjusting member 112, the resistance adjusting member 112 undergoes reset switching from a low resistance state to a high resistance state.

That is, when the low voltage of the voltage V0 is applied, the resistance adjusting member 112 undergoes the reset switching from the low resistance state to the high resistance state.

The voltage V0 represents a first voltage, a reset threshold voltage.

After the reset switching, when the voltage applied to the resistance adjusting member 112 increases from V0 to V1, V2, and V3, the resistance value of the resistance changing element also increases with the increased voltage. That is, if the voltage applied to the resistance change element is increased, the resistance value of the resistance change element may increase as the voltage increases.

The resistance value of the resistance variable element increases after the reset switching and before the applied voltage becomes V1 or higher. However, if the voltage supply is stopped, the resistance value of R0 is maintained. The resistance value of the resistance variable element can be maintained when the voltage is higher than V1 and the applied voltage is higher than V2, even if the resistance value increases with increasing voltage but the voltage supply is stopped. The change in the resistance value of the resistance change element can be applied in the same manner to the voltage not less than V2 and not less than V3. In other words, if the voltage application is stopped before the set switching occurs after the reset switching, the resistance value of the resistance change element has a resistance value according to the magnitude of the applied voltage, and the resistance value can be maintained until the next switching occurs have.

On the other hand, when the automatic transmission gear or the manual transmission gear is located in the parking space to suppress the exhaust sound during idling, the flow of the electric signal can be interrupted.

Conversely, when the shift gear is in neutral, forward, and reverse, the flow of electrical signals may not be controlled.

Hereinafter, the control unit 200 will be described in detail.

The control unit 200 is accommodated in the housing corresponding to the size of the circuit chip by overlapping two circuit chips. 2, the controller 200 may be divided into a first circuit and a second circuit. The first magnetic circuit 210 and the second magnetic circuit 210 are electrically connected to the first circuit, ) Is converted into a sound wave through the converter 220 in the second circuit, and the noise is attenuated by the noise filter 230 to generate an output sound to the output speaker 300.

The MIDI chip 210 may further include a storage device. This allows the user to selectively store the desired exhaust sound in the storage device of the MIDI chip 210 to receive the output sound. Alternatively, a plurality of storage spaces may be provided in the MIDI chip 210 to store a variety of exhaust sounds, so that a user may select a desired exhaust sound. For example, the output sound may be generated by storing the turbocharger exhaust sound, the imported vehicle exhaust sound, and the exhaust sound similar to the animal sound in the MIDI chip 210.

The converter 220 converts an electrical signal into a sound wave. As described above, the converted sound wave can attenuate noise or the like in the noise filter 230. Further, it is also possible to change the equalizer of the exhaust sound to tune the sound to a satisfactory level to the user, thereby generating the output sound.

Meanwhile, the exhaust sound output from the system may vary as the number of stages of the transmission gear changes. For example, when the gear changes from the first stage to the second stage, the central control unit 200 determines that the gear is changed, converts the sound into a converter 220, and transmits the electric signal to the output speaker 300 as a sound wave. It goes without saying that the exhaust sound output varies even when the number of stages of the transmission gear changes from the second stage to the third stage or from the third stage to the fourth stage.

Further, in the case of CVT, since there is no change in the speed ratio of the transmission, it is possible to output the exhaust sound as if the transmission gear changes according to the speed change. For example, if the first 0 km to 30 km is determined to be the first gear, and if the 30 km is exceeded, it is determined that the second gear has been converted and the exhaust sound may be output in a different manner. The above-mentioned speed is described in the above-mentioned example, and the speed at which the output of the exhaust sound according to the transmission gear change in the continuously variable transmission can be adjusted within the scope of the present invention.

When the system of the present invention is applied to the continuously variable transmission as described above, it is possible to increase the fun of the operation by outputting the exhaust sound according to the change of the transmission gear after leaving the flat operation.

The noise attenuated and tuned output sound in the noise filter 230 can finally be heard by the user through the output speaker 300.

The output speaker 300 may be installed on the outside or the inside of the vehicle, and the position of the output speaker 300 is not limited to one point. However, when the output speaker 300 is installed facing the driver, It is preferable to install it avoiding the direction of the driver.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. And various modifications and variations are possible within the scope of the appended claims.
