[0015] The controller may adjust the output level of the speaker corresponding to the rotation direction of the steering wheel among the first speaker and the second speaker, and may adjust the phase of the speaker corresponding to the direction opposite to the rotation direction of the steering wheel among the first speaker and the second speaker.

[0016] The controller may adjust the output level and phase delay to be proportional to the rotation angle of the steering wheel.

[0017] According to an aspect of the present invention, a control method of a vehicle, the vehicle including: a headlamp, a headlamp housing provided with the headlamp, a speaker disposed in the headlamp housing for outputting a virtual engine sound, and a temperature sensor for sensing the internal temperature of the headlamp housing, the method may include: controlling the output of the speaker to be inversely proportional to the internal temperature of the headlamp housing.

[0022] The speaker may include a diaphragm disposed toward the front of the vehicle, and at the position where the speaker is disposed, the area of the speaker is equal to the internal cross-sectional area of the headlamp housing.

[0023] The speaker may include: a first speaker disposed in the left headlamp housing; and a second speaker disposed in the right headlamp housing.

[0045] Hereinafter, the working principle and embodiments of the present invention will be described with reference to the drawings.

[0046] Figure 1 The appearance of a vehicle according to an exemplary embodiment is shown.

[0047] Reference Figure 1 , a headlight unit 13 for emitting light illumination in the traveling direction of the vehicle 1 can be provided at the front of the vehicle 1. The headlight unit 13 can include a left headlight unit 13a provided on the left side based on the direction toward the front of the vehicle 1 and a right headlight unit 13b provided on the right side.

[0048] The vehicle 1 can be an environmentally friendly vehicle using electric energy (which includes an electric motor for providing power), such as an electric vehicle and a hybrid electric vehicle.

[0049] Accordingly, in the case of traveling using the electric motor, the vehicle 1 can include a virtual engine sound system (VESS), and can include a speaker for outputting the virtual engine sound. Hereinafter, the speaker for outputting the virtual engine sound will be described in detail.

[0050] Figure 2 A cross-sectional view of the headlamp unit 13 according to an embodiment is shown.

[0051] Reference Figure 2 , the headlamp unit 13 according to an embodiment can include a headlamp 101 and a headlamp housing 102 provided with the headlamp 101.

[0052] The headlamp housing 102 can include a speaker 150 for outputting the virtual engine sound. That is, the speaker 150 can correspond to the speaker of the VESS, and when the vehicle 1 is driven by the power of the electric motor, the speaker 150 can output the virtual engine sound.

[0053] As described above, the vehicle 1 according to an embodiment includes the speaker 150 for outputting the virtual engine sound to the headlamp unit 13, and can improve the sound energy transmission efficiency of the virtual engine sound compared to the case where the impedance is inside the high bumper.

[0054] The speaker 150 according to an embodiment includes a diaphragm 150a disposed toward the front of the vehicle 1. Preferably, at the position 0 where the speaker 150 is provided, the area of the speaker 150 is equal to the internal cross-sectional area S0 of the headlamp housing 102. In addition, the speaker 150 can be arranged such that the cross-sectional area is horizontal with the diaphragm 150a.

[0055] By doing so, the speaker 150 can divide the headlamp housing 102 into a front region 102a and a rear region 102b based on the position 0 where the speaker 150 is provided, and can reduce the deviation between the front wave output from the speaker 150 and forward and the rear wave output from the speaker 150 and backward.

[0056] Thus, based on the position 0 where the speaker 150 is provided, by setting the cross-sectional area to be the same as the internal cross-sectional area S0 of the headlamp housing 102, the speaker 150 divides the headlamp housing 102 into a front region 102a and a rear region 102b. In addition, by using the rear region 102b as an enclosure, sound shortening can be prevented while enhancing the bass in the virtual engine sound.

[0057] In addition, based on the position 0 where the speaker 150 is provided, the internal cross-sectional area S of the headlight housing 102 according to the embodiment can be increased in the direction toward the front of the vehicle 1.

[0058] For example, the internal cross-sectional area S1 of the headlight housing 102 at a point x1 relatively close to the position 0 where the speaker 150 is provided can be narrower than the internal cross-sectional area S2 of the headlight housing 102 at a point X2 relatively far from the provided position 0.

[0059] That is, in the front region 102a of the headlight housing 102, a conical shape of a horn structure can be formed, and the conical structures 103a and 103b can be provided. However, according to the embodiment, the front region 102a of the headlight housing 102 itself can be provided in the shape of a horn, and in this case, the conical structures 103a and 103b can be omitted.

[0060] By doing so, compared with the output area of the speaker 150, due to the gradually increasing horn structure, the virtual engine sound output from the speaker 150 can have a higher radiation efficiency and can ultimately be amplified.

[0061] The structural features of the speaker 150 provided in the headlight unit 13 have been described herein. Hereinafter, the control of the speaker 150 based on the internal temperature of the headlight unit 13 or the rotation angle of the steering wheel (not shown) will be described in detail.

[0062] Figure 3 A control block diagram of the vehicle 1 according to the embodiment is shown. Figure 4 is a cross-sectional view when the headlight unit 13 according to the embodiment includes a temperature sensor. Figure 5 is a schematic diagram showing the output direction of the speaker when the driving route of the vehicle is straight ahead according to the embodiment. Figure 6 is a schematic diagram for explaining the directivity according to the phase difference between the first speaker and the second speaker according to the embodiment.

[0063] Reference Figure 3 , the vehicle 1 according to the embodiment includes: a temperature sensor 110, a steering angle sensor 120, a controller 130, an amplifier 140, and a speaker 150. The temperature sensor 110 is configured to detect the internal temperature of the headlight unit 13; the steering angle sensor 120 is configured to detect the rotation angle of the steering wheel; the controller 130 controls the speaker 150 based on the internal temperature of the headlight unit 13 or the rotation angle of the steering wheel; the amplifier 140 supplies current to the speaker 150 under the control of the controller 130; and the speaker 150 is provided in the headlight unit 13.

[0064] Specifically, the speaker 150 includes a first speaker 151 disposed in the left headlight unit (left headlight housing) 13a and a second speaker 153 disposed in the right headlight unit (right headlight housing) 13b. The first speaker 151 and the second speaker 153 may correspond to the same type of speaker.

[0065] As Figure 4 shown, the temperature sensor 110 according to the embodiment is a known type of sensor capable of measuring temperature. It is disposed inside the headlight housing 102 and can detect the internal temperature of the headlight housing 102.

[0066] The steering angle sensor 120 according to the embodiment may be a known type of sensor that detects the rotation angle of the steering wheel and outputs a value sensed by the controller 130.

[0067] The controller 130 according to the embodiment can control the amplifier 140 such that the speaker 150 outputs a virtual engine sound when the vehicle 1 is driven based on the power supplied from the motor.

[0068] The amplifier 140 can, under the control of the controller 130, send a sound signal corresponding to the virtual engine sound to the speaker 150. That is, the amplifier 140 can supply a current corresponding to the sound signal to the speaker 150.

[0069] The controller 130 according to the embodiment can control the output of the speaker 150 based on the internal temperature of the headlight housing 102. That is, the controller 130 can adjust the amount of current output from the amplifier 140 and supplied to the speaker 150 based on the output of the temperature sensor 110.

[0070] Specifically, the controller 130 can control the output of the speaker 150 to be inversely proportional to the internal temperature of the headlight housing 102. That is, the controller 130 can increase the amount of current output from the amplifier 140 such that the output of the speaker 150 increases as the internal temperature decreases, and can decrease the amount of current output from the amplifier 140 such that the output of the speaker 150 decreases as the internal temperature increases.

[0071] To compensate for the physical property that the sound wave transmission speed depends on temperature, even in the case of temperature change, the vehicle 1 according to the embodiment can provide a distortion-free virtual engine sound by adjusting the output of the speaker 150.

[0072] In addition, the controller 130 according to the embodiment can adjust the output level and phase of each of the first speaker 151 and the second speaker 153 based on the rotation angle and rotation direction of the steering wheel. That is, the controller 130 controls the amplifier 140 based on the output value of the steering angle sensor 120 to adjust the magnitude and timing of the current supplied to each of the first speaker 151 and the second speaker 153, so that the output level and phase of each of the first speaker 151 and the second speaker 153 can be adjusted.

[0073] Specifically, the controller 130 adjusts the output level of the speaker corresponding to the rotation direction of the steering wheel among the first speaker 151 and the second speaker 153 in the increasing direction, and can adjust the phase of the speaker corresponding to the direction opposite to the rotation direction of the steering wheel among the first speaker 151 and the second speaker 153 in the delaying direction.

[0074] When the vehicle 1 travels along a straight route, the virtual engine sound output from the first speaker 151 and the virtual engine sound output from the second speaker 153 can have the same magnitude and the same phase. Accordingly, the final virtual engine sound 500 can face forward corresponding to the traveling direction of the vehicle 1, as Figure 5 shown.

[0075] If the phase of the virtual engine sound output from the second speaker 153 is delayed based on the phase of the virtual engine sound output from the first speaker 151, the final virtual engine sound can have a directivity to the left of the first speaker 151.

[0076] As Figure 6 shown, as the phase delay of the second speaker 153 increases from 0 to 0.4 radians, 0.8 radians, and 1.2 radians, the final virtual engine sound can be more directive to the left. That is, as the phase delay of the second speaker 153 increases, the final virtual engine sound can move from the 500 position to the 530 position.

[0077] As described above, when the vehicle 1 turns left, the controller 130 adjusts the output level of the first speaker 151 on the left side in the increasing direction, and delays the phase of the second speaker 153 on the right side, so that the controller 130 can adjust the final virtual engine sound to point to the left.

[0078] In addition, when the vehicle 1 turns right, the controller 130 adjusts the output level of the second speaker 153 on the right side in the increasing direction, and delays the phase of the first speaker 151 on the left side, so that the controller 130 can adjust the final virtual engine sound to point to the right.

[0079] As described above, the vehicle 1 according to the embodiment provides the virtual engine sound to a position corresponding to the driving route of the vehicle 1 by controlling the speaker 150, so that the virtual engine sound has directivity in the turning direction, enabling pedestrians to accurately recognize the approach of the vehicle 1.

[0080] The controller 130 may adjust the output level and phase delay to be proportional to the rotation angle of the steering wheel. That is, as the rotation angle of the steering wheel increases, the controller 130 may adjust the output level and phase of the speaker in the increasing direction.

[0081] The controller 130 may include at least one memory and at least one processor. A program for performing the above operations and the operations described below is stored in the at least one memory; the at least one processor is configured to execute the stored program. In the case of having multiple memories and multiple processors, these memories and processors may be integrated in one chip or may be arranged at physically separate locations.

[0082] Hereinafter, a control method of the vehicle 1 according to the embodiment will be described. The vehicle 1 according to the above embodiment may be applied to the control method of the vehicle 1 described below. Therefore, even if not specifically mentioned, the content described with reference to Figures 1 to 6 is equally applicable to the control method of the vehicle 1 according to the embodiment.

[0083] Figure 7 is a flowchart showing a case of compensating the output of the speaker 150 based on the output of the temperature sensor in the control method of the vehicle 1 according to the embodiment.

[0084] Referring to Figure 7 , the vehicle 1 according to the embodiment may sense the internal temperature (710) of the headlight housing 102.

[0085] That is, the controller 130 may sense the internal temperature of the headlight housing 102 based on the output of the temperature sensor 110 provided in the headlight housing 102.

[0086] The vehicle 1 according to the embodiment may control the output of the speaker 150 to be inversely proportional to the internal temperature of the headlight housing 102 (720).

[0087] Specifically, the controller 130 may control the output of the speaker 150 to be inversely proportional to the internal temperature of the headlight housing 102. That is, the controller 130 may increase the magnitude of the current output from the amplifier 140 so that the output of the speaker 150 increases as the internal temperature decreases. Additionally, the controller 130 may decrease the magnitude of the current output from the amplifier 140 so that the output of the speaker 150 decreases as the internal temperature increases.

[0088] This is to compensate for the physical characteristic that the sound wave transmission speed varies with temperature. Even when the temperature changes, the vehicle 1 according to the embodiment also adjusts the output of the speaker 150, so as to generate a distortion-free virtual engine sound.

[0089] Figure 8 It is a flowchart showing the situation of adjusting the directivity of the speaker 150 based on the rotation angle of the steering wheel in the control method of the vehicle 1 according to the embodiment.

[0090] Reference Figure 8 According to the embodiment, the vehicle 1 can detect the rotation angle of the steering wheel (810).

[0091] That is, the controller 130 can sense the rotation angle of the steering wheel based on the output of the steering angle sensor 120.

[0092] According to the embodiment, the vehicle 1 can adjust the output level of the speaker 150 corresponding to the rotation direction of the steering wheel to increase (820), and can adjust so that the phase of the speaker 150 corresponding to the direction opposite to the rotation direction of the steering wheel is delayed (830).

[0093] That is, when the vehicle 1 turns left, the controller 130 adjusts the output level of the first speaker 151 on the left side in the increasing direction, and delays the phase of the second speaker 153 on the right side, so that the controller 130 can adjust the final virtual engine sound to point to the left.

[0094] Similarly, when the vehicle 1 turns right, the controller 130 adjusts the output level of the second speaker 153 on the right side in the increasing direction, and delays the phase of the first speaker 151 on the left side, so that the controller 130 can adjust the final virtual engine sound to point to the right.

[0095] At this time, the controller 130 can adjust the output level and phase delay to be proportional to the rotation angle of the steering wheel. That is, as the rotation angle of the steering wheel increases, the controller 130 can adjust the output level and phase of the speaker in the increasing direction.

[0096] As described above, the vehicle 1 according to the embodiment provides the virtual engine sound to a position corresponding to the driving route of the vehicle 1 by controlling the speaker 150, so that the virtual engine sound has directivity in the turning direction, enabling pedestrians to accurately recognize the approach of the vehicle 1.

[0097] A non-transitory computer-readable recording medium includes all types of recording media that store data readable by a computer system. Examples of computer-readable recording media include read-only memory (ROM), random access memory (RAM), magnetic tapes, magnetic disks, flash memories, optical data storage devices, and the like.
