DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method of providing a virtual engine sound and a virtual vibration according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram showing a rough configuration of the present invention.

As shown in FIG. 1, a device structure for implementing the present invention includes a front speaker 1 provided on a front surface of a vehicle, a rear speaker 2 provided on a rear surface of the vehicle, an internal speaker (3), a driver's seat (d) and a vibration terminal (4) provided on the steering wheel.

Although not shown in the drawings, the present invention further includes a control unit for controlling operations according to each step of the present invention.

2 is a block diagram showing each step of the present invention.

As shown in FIG. 2, the method includes a setting step S10, a sound output step S20, a vibration output step S30, a sound control step S40, and a vibration control step S50.

Specifically, the setting step S10 is a step of selecting and setting the preferred engine sound and the vibration intensity, and the preference engine sound can be selectively changed through the control unit provided in the vehicle. The control unit may be implemented through a central processing unit (CPU, MCU, etc.), and the preferred engine sound may be provided for each vehicle type preferred by the driver, as well as a large-sized vehicle such as a motorcycle, Can also be selected as the name of the driver.

In addition, it is preferable that the selection of the vibration intensity enables selection of different intensity of vibrations for vehicles of different kinds and for different vehicles, and in particular, sound and vibration are selected so as to satisfy the driver's preference.

Here, the engine sound includes not only a sound of an engine but also a preferred vehicle type or an exhaust sound of other vehicles, and it is possible to provide a feeling of realistic driving feeling through the output of such exhaust sound.

Next, the sound output step S20 is a step of outputting the engine sound through the speakers 1, 2, and 3 installed on the front, rear, and inside of the vehicle when the starter is driven. The engine sound is output to the front of the vehicle through the front speaker 1 of the vehicle as described above and the engine sound is output to the rear of the vehicle through the rear speaker 2, It can be heard indoors.

Accordingly, the driver can overcome the somewhat flat feeling of driving of the vehicle using the silent power source (electricity, hydrogen, solar battery, etc.) without the engine sound by running while listening to the selected engine sound through the sound output step S20.

Next, the vibration output step S30 is a step of outputting vibration corresponding to the vibration intensity set through the plurality of vibration terminals 4 provided on the steering wheel and the driver's seat d of the vehicle when the starter is driven, The driver can sense driving feeling by feeling the generated vibration through the vibration output step (S30), and feel a thrilling driving feeling.

The vibration terminal 4 generates a self-vibration by an applied power source. Even if a detailed description is omitted, the vibration terminal 4 can be practiced by a person skilled in the art.

Next, the sound control step S40 is a step of controlling the volume adjustment and on / off of the speakers 1, 2, and 3, wherein the speakers 1, 2, , And indoor speakers. Also, volume control and on / off control may be performed through the control unit described above.

In addition, through the sound control step S40, it is possible to easily inform the existence of the vehicle by raising the volume of the front speaker 1 in a frequent passage such as a residential area or a busy street, such as a person or an animal, without sounding a horn separately.

Finally, the vibration control step S50 is a step of controlling the vibration intensity of the vibration terminal 4 and controlling on / off. The vibration intensity corresponding to the driver's personal preference is set so as to avoid the inconvenience of driving. Further, in the above-mentioned vibration output step (S30), the vibration intensity corresponding to the vehicle type or other vehicle preferred by the user is provided, If the intensity of the vibration is required to be lowered, such as when it is necessary to adjust the vibration intensity, such as when the elderly person or the pregnant woman is riding, for example, The vibration control step S50 may be performed to lower the vibration intensity.

On the other hand, in the case of an engine vehicle, engine sounds, exhaust sounds, and vehicle vibrations increase when the number of revolutions increases according to the number of revolutions (rpm) of the motors. The present invention further includes a step for implementing engine sound, exhaust sound, and vehicle vibration according to the number of revolutions of the motor.

2 is a flowchart illustrating a method of detecting an engine sound, an exhaust sound, and a vehicle vibration according to the number of revolutions of the motor, . Through the speed and speed change amount detection step S60, the absolute speed and speed change amount values corresponding to the number of revolutions of the motor are digitized and detected, and using this, the engine sound size, the exhaust sound size, and the vibration A change in intensity magnitude can be realized.

2, the method includes a sound matching step of adjusting the output of the engine sound through the detected amount of change in the vehicle speed (step < RTI ID = 0.0 > S200) and a vibration intensity matching step (S300) for adjusting the output intensity of the vibration.

More specifically, the sound matching step S200 is a step of adjusting the output intensity of the engine sound to match with the corresponding speed variation amount of the vehicle, and the output intensity of the engine sound to be output becomes larger as the speed variation amount of the vehicle is larger do.

In addition, the vibration intensity matching step S300 is a step of adjusting the output intensity of the output vibration matching the corresponding speed change amount of the vehicle, and the output intensity of the vibration is increased as the speed change amount of the vehicle is larger.

In addition, the magnitude of the engine sound and the intensity of the generated vibration vary depending on the absolute speed, even in the case of a variation value of the same speed. In the sound matching step S200 and the vibration intensity matching step S300, Reflecting the intensity of the vibration, at higher speeds, the sound output intensity is increased, and the output vibration intensity is also increased. In addition, at low speeds, the sound output intensity is lowered and the output vibration intensity is also lowered.

Through the speed and speed variation detection step S60, the sound matching step S200, and the vibration intensity matching step S300 of the vehicle, the driver can feel a vivid driving feeling according to the absolute speed and the variation amount of the speed. Also, it is possible to indirectly experience the feeling of a preferred car or other vehicle, thereby satisfying the satisfaction of the consumer.

On the other hand, referring to FIG. 2, in order to provide a vivid driving feeling according to the vibration output, it is additionally possible to confirm the execution of the suit that the driver wears directly on the driver's seat (d).

2, the vibration output step S30 of the present method corresponds to the corresponding speed of the vehicle through the vibration terminal 4 inserted in the driver's suit Suit provided in the vehicle, And outputting a vibration matched to the speed and the speed change amount detected through the speed and speed change amount detection step S60 corresponding to the vibration intensity.

Through the chute vibration output step S310, the driver can experience a more dynamic driving feeling by further strengthening the virtual vibration according to the speed and the speed change amount that can be felt through the driver's seat (d) and the steering wheel.

In addition, another feature of the present invention is that the operation of steps S10 to S60 may be performed in conjunction with an external device as well as a software module mounted on the vehicle.

Meanwhile, the present invention is applied to a vehicle using a silent power source. In general, such a vehicle is charged with a battery using an external power source s periodically in a concept similar to that of a general vehicle.

However, after the charging is completed, it is preferable to cut off the application of the external power source s supplied to the battery in order to reduce the power loss. When the application of the external power source s supplied to the battery during charging is interrupted The internal configuration circuit of the vehicle including the control unit is forced to receive power from the battery and opens the door of the vehicle through the remote controller and drives the starter during charging, The battery is consumed.

In order to solve this problem, the present invention is characterized in that a power supply means is provided for supplying power to the internal constituent circuit when external power is supplied to the battery and when external power is not supplied to the battery.

In particular, the driving of the starter which is turned on / off remotely by the remote controller when supply power is to be supplied to the internal constituent circuit will be described.

Particularly, the power supply unit 51 operates the external power supply circuit 511 during the ON operation of the switch unit 52 to generate the power supply voltage Vcc by using the external power supply s and turns off the switch unit 52 In operation, the internal power supply circuit 513 is operated to generate an internal power supply from the external power supply s, and the power supply voltage Vcc is generated using the internal power supply.

Here, the supply voltage Vcc is a power generated by the external power supply s or the internal power supply and applied for the operation of each configuration.

More specifically, the external power supply circuit 511 of the power supply unit 51 includes a capacitor C1 and a first rectification diode BD1 serially connected to the external power source s, a charge capacitor C5 connected thereto in parallel, .

The internal power supply circuit 513 includes a bridge diode BD3 connected in parallel to the external power supply s, a transformer T1 and a second rectifier diode BD2 connected in parallel thereto, a charge capacitor C5).

In the above description, the charging capacitor C5 has the same configuration and is configured to be charged by the current rectified by the DC by the first and second rectifying diodes BD1 and BD2. The charging capacitor C5 stores and outputs the supply voltage Vcc .

The output terminals of the external power supply circuit 511 and the internal power supply circuit 513 are connected to each other. That is, the output terminal of the first rectifier diode BD1 and the output terminal of the second rectifier diode BD2 are connected to each other.

 Next, the switch unit 52 is configured to select the operation of the external power supply circuit 511 or the internal power supply circuit 513 and is composed of a switching element Q1 (Triac) connected in series with the bridge diode BD3 . The ON / OFF determination signal of the switch unit 52 can be received from outside or inside the apparatus.

The stabilization circuit includes a first rectification diode BD1 and a second rectification diode BD2, A capacitor C4 connected in parallel to the zener diode ZD1 and a capacitor C4 connected in parallel to the output terminal of the inductor L1 connected to the charge capacitor C5 and the zener diode ZD1, .

3, the circuit operation of the power supply unit 5 will be briefly described. First, when a switch-on signal is inputted to the switch unit 52 (supply of the external power supply s is stopped) The switch unit 52 is turned off so that the bridge diode (BD1) is turned on and the bridge diode (BD1) is turned on, BD3) -switching element Q1 'are mutually opened. Therefore, as described above, the power supply unit 51 provides the supply power Vcc in two cases when the switch unit 52 is on and off.

First, the operation of the circuit in which the switch unit 52 is turned on will be described. In this case, the switching element Q1 is short-circuited and a current flows through the bridge diode BD3-switching element Q1 ' . The voltage across the bridge diode BD3 is transformed by the transformer T1 and is rectified to the direct current via the second rectifier diode BD2 and then charged to the charge capacitor C5.

Thus, when the supply of external power supply s is interrupted, the generation of the internal voltage utilizes the voltage drop in the bridge diode BD3, the role of the original bridge diode is for rectification (first and second rectifier diodes BD1) (BD2)), a voltage drop can be induced by shorting two non-adjacent rectifying terminals of the bridge diode (the bridge diode is composed of four rectifying terminals connected in circulation). The generation of such internal power supply has the same effects as those of the bridge circuit using four separate diodes, but also has the effects of reducing the number of parts, reducing the size of the mounting, reducing the cost, and reducing the probability of occurrence of failure.

Next, the operation of the circuit when the switch unit 52 is turned off will be described. The switching element Q1 is opened, and the transformer T1, the resistor R2, and the capacitor (C1) - the first rectifying diode (BD1) - the dropout resistance (R3) 'due to the impedance difference between the line (C1) and the capacitor (C1) - the first rectifying diode (BD1) (R3) 'line. Therefore, the AC current generated by the external power source s flows through the capacitor C1 to the first rectifier diode BD1, is rectified by the first rectifier diode BD1, and is charged in the charging capacitor C5.

At this time, the zener diode ZD1 connected in parallel to the output terminals of the first rectifying diode BD1 and the second rectifying diode BD2, which are stabilizing circuits, prevents the overvoltage, and the inductor L1 and the capacitor C4 rectify the rectified DC The noise component included in the signal is removed.
