[0033] Figure 1 2 is a schematic diagram showing the appearance of a vehicle according to an exemplary embodiment. Figure 1 The vehicle 1 may include a body 10, a windshield 11, side mirrors 12, doors 13, and wheels 21 and 22; the body 10 forms the appearance (e.g., shape or model) of the vehicle 1; the windshield 11 provides the driver with a front view of the vehicle 1; the side mirrors 12 provide the driver with a rear view of the vehicle 1; the doors 13 protect the interior of the vehicle 1 from external influences; the wheels 21 and 22 move the vehicle 1 by including a front wheel 21 arranged on the front side of the vehicle and a rear wheel 22 arranged on the rear side of the vehicle.

[0034] The windshield 11 may be arranged at an upper portion in front of the vehicle body 10, so that a driver in the vehicle 1 can obtain visual information about the front of the vehicle 1. The side rearview mirrors 12 may include a left rearview mirror arranged on the left side of the vehicle body 10 and a right rearview mirror arranged on the right side of the vehicle body 10, and may enable the driver in the vehicle 1 to obtain visual information of the side and rear of the vehicle 1. The door 13 may be rotatably arranged on the right and left sides of the vehicle body 10. When the door 13 is opened, the driver can enter the vehicle 1, and when the door 13 is closed, the interior of the vehicle 1 can be isolated from the outside.

[0035] In addition to the above components, the vehicle 1 may include a drive device (not shown) configured to rotate the wheels 21 and 22, a steering system (not shown) configured to change the driving direction of the vehicle 1, and a braking system (not shown) configured to stop the driving of the wheels. The drive device 16 may be configured to provide torque to the front wheels 21 or the rear wheels 22 to move the vehicle body 10 forward and backward. The drive device 16 may include an engine configured to generate torque by burning fuel or a high-voltage battery 120 (see FIG. 1 ). Figure 2 ) receives electric power and generates torque from the motor 180 (see Figure 2 ) at least one of ).

[0036] In other words, the vehicle 1 corresponds to an electric vehicle (EV) or a hybrid electric vehicle (HEV) and may include a motor 180 (see Figure 2 ). When the vehicle 1 corresponds to an HEV, the vehicle 1 may further include an engine. The steering system may include: a steering wheel (not shown) that receives a driving direction from a driver, a steering gear (not shown) that changes the rotational motion of the steering wheel into a reciprocating motion, and a steering link (not shown) that transmits the reciprocating motion of the steering gear (not shown) to the front wheel 21. Therefore, the steering system can change the driving direction of the vehicle 1 by changing the direction of the rotation axis of the wheel.

[0037] The braking system may include a brake pedal (not shown) that receives a braking operation from the driver, a brake drum (not shown) coupled to the wheels 12 and 22, and a brake shoe (not shown) that uses friction to stop the rotation of the brake drum (not shown). Therefore, the braking system may be configured to decelerate and stop the travel of the vehicle 1 by stopping the rotation of the wheels 21 and 22. In addition, the solar charging panel 17 may be installed on the roof of the vehicle 1 as a configuration for solar charging, however, the installation location is not limited thereto. A detailed description thereof will be given later.

[0038] Figure 2 FIG. 1 is a control block diagram of a vehicle according to an exemplary embodiment. Figure 2 The vehicle 1 may include a solar charging panel 110, a high-voltage battery 120, an auxiliary battery 130, a battery sensor 140, a storage 150, a display 160 and a controller 170; the solar charging panel 110 is configured to measure the amount of sunlight and generate electricity based on solar energy; the high-voltage battery 120 is configured to supply power to the motor 180; the auxiliary battery 130 is configured to supply power to the electric field load 190; the battery sensor 140 is configured to measure the state of charge (SOC) of the high-voltage battery 120 and the SOC of the auxiliary battery 130; the storage 150 is configured to store various information required to drive the vehicle 1; the display 160 is configured to display the SOC of the high-voltage battery 120; the controller 170 is configured to calculate the power that can be generated by the solar charging panel 110 based on the measured amount of light.

[0039] In addition, the controller may be configured to: when the vehicle 1 is not started, in the case where the power that can be generated is greater than the power consumption during the power generation, operate the solar charging panel 110 to generate power, and based on the SOC of the high-voltage battery 120 and the SOC of the auxiliary battery 130, operate the solar charging panel 110 to supply the generated power to the high-voltage battery 120 or the auxiliary battery 130. The vehicle may further include a motor 180 and an electric field load 190; the motor 180 is configured to provide a rotational force to the front wheel 21 or the rear wheel 22 corresponding to the drive device 16; and the electric field load 190 is configured to perform various functions of the vehicle 1. When the driver starts the ignition, the vehicle is in a started state. And, when the driver turns off the ignition, the vehicle is in a non-started state.

[0040] The solar charging panel 110 can be configured to charge solar energy into the high-voltage battery 120 and the auxiliary battery 130 (for example, transmit solar energy to the battery). The solar charging panel 110 can be configured to apply a power generation system that directly converts solar energy into electricity (current) through solar cells, and the solar cells can be formed to convert light energy into electrical energy. Solar cells may include p-type semiconductors and n-type semiconductors, and when irradiated with light, charges move to generate a potential difference. When the solar cell is mounted on the roof of the vehicle, electrical energy can be generated using natural light supplied by the sun. In other words, the solar charging panel 110 can be composed of solar cells to generate electricity based on solar energy.

[0041] In addition, the solar charging panel 110 can be configured to measure the amount of sunlight. Specifically, the solar charging panel 110 can be configured to measure the amount of sunlight based on the electricity generated in proportion to the amount of sunlight. In other words, the solar charging panel 110 can be configured to measure the amount of sunlight based on the intensity of the electricity generated. In addition, the solar charging panel 110 may include a light intensity measuring sensor (not shown) configured to measure the amount of sunlight. When the vehicle 1 is not started, the solar charging panel 110 can be operated by the controller 170 to supply the generated electricity to the high-voltage battery 120 or the auxiliary battery 130. Therefore, the high-voltage battery 120 or the auxiliary battery 130 can be charged based on the electricity supplied by the solar charging panel 110.

[0042] The location where the solar charging panel 110 is installed on the vehicle 1 is not limited to the roof, and the solar charging panel 110 can be installed at any location on the vehicle 1 that can charge the battery. The high-voltage battery 120 can be configured to supply power to the motor 180 (which provides rotational force for the wheels 21 and 22). In other words, the high-voltage battery 120 can be configured to store power for driving the motor 180, and can correspond to a high-voltage large-capacity battery for driving the motor 180. The high-voltage battery 120 can be a lithium battery. The auxiliary battery 130 can refer to a low-voltage battery, and can be configured to supply the power required to start the engine of the vehicle 1 and the power consumed in the electric field load 190 (electrical component).

[0043] The battery sensor 140 can be configured to measure the state of charge (SOC) of each of the high-voltage battery 120 and the auxiliary battery 130 by measuring the voltage, current and temperature of the high-voltage battery 120 and the auxiliary battery 130. The SOC can indicate the capacity difference between the current battery and the fully charged battery. As described above, the battery sensor 140 can be provided in a plurality of units and can be arranged at each terminal of the high-voltage battery 120 and the auxiliary battery 130 to measure the input power or the output power. Therefore, each battery sensor 140 can be composed of a current sensor, a voltage sensor, etc.

[0044] In addition, the storage 150 may be configured to store various information about the operation of the vehicle 1. Specifically, the storage 150 may be configured to store information about the reference SOC of the high-voltage battery 120. At this time, the reference SOC of the high-voltage battery 120 may be preset and stored in the design stage, and when the power generated by the solar charging panel 110 is supplied, the reference SOC of the high-voltage battery 120 may be used to determine the supply priority to the auxiliary battery 130. When the SOC of the high-voltage battery 120 is lower than the reference SOC, in the case where the vehicle 1 corresponds to a hybrid vehicle, the high-voltage battery 120 may be charged using the electric energy generated by motor regeneration based on the margin output of the engine of the vehicle 1. The storage 150 may be configured to store information about the reference SOC of the auxiliary battery 130, the normal control lower limit SOC, the first threshold SOC, and the second threshold SOC.

[0045] When the SOC of the auxiliary battery 130 is lower than the reference SOC, the measurement of the remaining SOC of the auxiliary battery 130 becomes inaccurate, and thus the reference SOC of the auxiliary battery 130 may refer to a minimum SOC for protecting the auxiliary battery 130. In other words, the reference SOC of the auxiliary battery 130 may be preset and stored at the design stage, and when the power generated by the solar charging panel 110 is supplied, the reference SOC of the auxiliary battery 130 may be used to determine the supply priority to the high voltage battery 120.

[0046] The normal control lower limit SOC of the auxiliary battery 130 may refer to the lower limit SOC of the stable state in which the electric field load 190 supplies the optimal power. The first threshold SOC and the second threshold SOC of the auxiliary battery 130 may be preset and stored in the design stage, and when the power generated by the solar charging panel 110 is supplied, the first threshold SOC and the second threshold SOC of the auxiliary battery 130 may be used to determine the supply priority to the high voltage battery 120. In addition, the storage 150 may be configured to store information indicating the relationship between the amount of sunlight and the power that can be generated in the solar charging panel 110 (e.g., the power that can be generated), and may be configured to store information about the power consumption consumed during power generation.

[0047] The storage 150 can be implemented as at least one of a non-volatile storage device (e.g., cache, ROM, PROM, EPROM, EEPROM, and flash memory), a volatile storage device (e.g., RAM), or a storage medium (e.g., HDD and CD-ROM) to store various information, but is not limited to these.

[0048] In addition, the display 160 may be arranged in the vehicle 1 to display the SOC of the high-voltage battery 120. Therefore, the user of the vehicle 1 can recognize the SOC of the high-voltage battery 120. The display 160 may be located in a combined instrument panel (not shown) in the vehicle 1, or may be located in an upper panel of an instrument panel (not shown). However, the location where the display 160 is installed is not limited to the above example, and the display 160 may be located at a location where the SOC of the high-voltage battery 120 can be provided to the user in the vehicle 1. In addition, the display 160 may include a panel, and the panel may be a cathode ray tube (CRT) panel, a liquid crystal display (LCD) panel, a light emitting diode (LED) panel, an organic light emitting diode (OLED) panel, a plasma display panel (PDP), or a field emission display (FED) panel.

[0049] The controller 170 may be configured to determine whether the vehicle 1 is started or not started based on whether the key of the vehicle 1 is in the ON / OFF position. In other words, when the driver turns on the ignition, the vehicle starts, and when the driver turns off the ignition, the vehicle does not start. However, when the variable value of the vehicle 1 can be used to determine whether the vehicle 1 is started or not started, the variable value may be used without limitation to determine whether the vehicle is started or not started. When the vehicle 1 is not started, the controller 170 may be further configured to calculate the power that can be generated by the solar charging panel 110 based on the amount of light measured by the solar charging panel 110. At this time, the controller 170 may be configured to calculate the power that can be generated based on information indicating the relationship between the amount of sunlight stored in advance and the power that can be generated in the solar charging panel 110.

[0050] The calculated generable power may refer to the power that can be generated per unit time by the solar charging panel 110. The controller 170 may be configured to compare the calculated generable power with the power consumption consumed during power generation, and to operate the solar charging panel 110 to generate power when the calculated generable power is greater than the power consumption. Specifically, the power consumption consumed during power generation may correspond to the basic power consumption per unit time consumed when the solar charging panel 110 generates power, and may include the power consumption under the operation of the controller 170 and the power consumption according to the measurement of the battery sensor 140. The power consumption consumed during power generation may correspond to the power consumption consumed during power generation by the solar charging panel 110.

[0051] The controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high voltage battery 120 or the auxiliary battery 130 based on the SOC of the high voltage battery 120 and the SOC of the auxiliary battery 130 when the vehicle 1 is not started. This will be described in detail later. The controller 170 may include at least one memory configured to store a program for performing the above-mentioned operations and the following operations and at least one processor that executes the stored program. When there are multiple memories and processors, these memories and processors may be integrated in one chip, or may be provided in physically separate locations.

[0052] The motor 180 may be configured to provide rotational force to the front wheel 21 or the rear wheel 22 corresponding to the drive device 16. The electric field load 190 corresponds to electrical components that perform various functions of the vehicle 1, and may include lights, air conditioning, a black box device, a window adjustment device, etc. of the vehicle 1, and may be included in any electrical component capable of performing various functions of the vehicle 1 without limitation.

[0053] Figure 3 Schematic diagram showing whether electricity is generated by a solar charging panel according to an exemplary embodiment. Figure 3 , the controller 170 may be configured to calculate the power that can be generated by the solar charging panel 110 based on the amount of light measured by the solar charging panel 110 when the vehicle 1 is not started. At this time, the controller 170 may be configured to calculate the generable power based on information indicating the relationship between the amount of light stored in advance and the generable power that can be generated in the solar charging panel 110. The calculated generable power may refer to the power that can be generated per unit time by the solar charging panel 110. The controller 170 may be configured to compare the calculated generable power with the power consumption consumed during power generation, and when the calculated generable power is greater than the power consumption, to control the solar charging panel 110 to generate power.

[0054] In other words, when the calculated generable power is greater than the power consumption during power generation, the controller 170 may be configured to operate the solar charging panel 110 to generate power. When the calculated generable power is less than the power consumption during power generation, the controller 170 may also be configured to prevent the solar charging panel 110 from performing power generation. In this example, the power consumption consumed during power generation may correspond to the basic power consumption per unit time consumed when the solar charging panel 110 generates power, and may include the power consumption under the operation of the controller 170 and the power consumption according to the measurement of the battery sensor 140.

[0055] Therefore, the vehicle 1 may be configured to determine whether to generate electricity through the solar charging panel 110 in consideration of the amount of sunlight that may vary according to the characteristics of the space where the vehicle 1 is parked, the weather characteristics, and the time characteristics. In other words, the vehicle 1 can generate electricity through the solar charging panel 110 only when the power that can be generated according to the current amount of sunlight is greater than the power consumption during power generation, thereby enabling the vehicle 1 to prevent the high-voltage battery 120 or the auxiliary battery 130 from being discharged due to the fact that the power that can be generated is less than the power consumption during power generation.

[0056] Figure 4 Schematic diagram showing the direction of power supply in a vehicle according to an exemplary embodiment. Figure 4 , the vehicle 1 may include a solar charging panel 110, a high voltage battery 120, a low voltage DC-DC converter (LDC) 125, and an auxiliary battery 130. Figure 4 As shown, when the vehicle 1 is not started, the electric power generated by the solar charging panel 110 may be supplied to the high voltage battery 120 or the auxiliary battery 130 .

[0057] When the power stored in the auxiliary battery 130 is insufficient, the power stored in the high-voltage battery 120 can be used to charge the auxiliary battery 130 through the LDC 125. Specifically, the LDC 125 can be configured to convert the high direct current (DC) voltage of the high-voltage battery 120 into a low DC voltage. The LDC 125 can also be configured to convert the high direct current (DC) voltage of the high-voltage battery 120 into an alternating current (AC) voltage, step down the AC voltage through a coil, a transformer, a capacitor, etc., and then rectify the voltage to convert the high DC voltage into a reduced voltage. The reduced DC voltage can be supplied to the auxiliary battery 130 to charge the auxiliary battery 130.

[0058] In other words, when the power stored in the auxiliary battery 130 is insufficient, the power consumption from the high voltage battery 120 to the LDC 125 during the travel of the vehicle 1 increases, and therefore, the fuel efficiency of the vehicle 1 may decrease. Therefore, in a state where the vehicle 1 is not started, the vehicle 1 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high voltage battery 120 or the auxiliary battery 130 based on the SOC of the high voltage battery 120 and the SOC of the auxiliary battery 130. In response to determining that the SOC of the auxiliary battery 130 is insufficient when the vehicle 1 is not started, the vehicle 1 may improve fuel efficiency by operating the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130.

[0059] Hereinafter, an algorithm for supplying the power generated by the solar charging panel 110 to the high voltage battery 120 or the auxiliary battery 130 will be described in detail. Figure 5 2 is a diagram illustrating battery charging priority in a vehicle according to an exemplary embodiment.

[0060] refer to Figure 5 , the controller 170 may be configured to determine the battery to be supplied with the power generated by the solar charging panel 110 based on the SOC of each of the high-voltage battery 120 and the auxiliary battery 130 measured by the battery sensor 140 when the vehicle 1 is not started. Specifically, in response to determining that the SOC of the auxiliary battery 130 is less than a predetermined reference SOC of the auxiliary battery 130, the controller 170 may be configured to operate the solar charging panel 110 to supply the auxiliary battery 130 with the power generated by the solar charging panel 110.

[0061] In addition, in response to determining that the SOC of the auxiliary battery 130 is equal to or greater than a predetermined reference SOC of the auxiliary battery 130, and the SOC of the high voltage battery 120 is equal to or greater than a predetermined reference SOC of the high voltage battery 120, the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130. In response to determining that the SOC of the auxiliary battery 130 is equal to or greater than a predetermined reference SOC of the auxiliary battery 130, and the SOC of the high voltage battery 120 is less than a predetermined reference SOC of the high voltage battery 120, the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high voltage battery 120.

[0062] Hereinafter, supplying the power generated by the solar charging panel 110 to the high voltage battery 120 or the auxiliary battery 130 according to the SOC of each of the high voltage battery 120 and the auxiliary battery 130 will be described in detail. Figure 6 and Figure 71 is a schematic diagram showing a case where the state of charge (SOC) of the high-voltage battery is equal to or greater than the reference SOC and the SOC of the auxiliary battery is equal to or greater than the reference SOC according to an exemplary embodiment. Hereinafter, the predetermined reference SOC of the high-voltage battery 120 refers to a first reference SOC, and the predetermined reference SOC of the auxiliary battery 130 refers to a second reference SOC.

[0063] When the vehicle 1 is not started, in the case where the SOC of the high voltage battery 120 is equal to or greater than a predetermined first reference SOC and the SOC of the auxiliary battery 130 is equal to or greater than a predetermined second reference SOC (d), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130. Since power is supplied to the electric field load 190 that performs a part of the function of the vehicle 1, the auxiliary battery 130 may be discharged even when the vehicle 1 is not started. For example, the auxiliary battery 130 may be configured to supply power to a black box device and an anti-theft sensor of the vehicle 1.

[0064] At this time, when the SOC of the auxiliary battery 130 of the vehicle 1 is low, the power of the high-voltage battery 120 may be consumed and the auxiliary battery 130 may be charged. Therefore, when the SOC of the high-voltage battery 120 and the SOC of the auxiliary battery 130 are both equal to or greater than the corresponding reference SOC, the controller 170 may be configured to operate the solar charging panel 110 to supply power to the auxiliary battery 130. However, even when the SOC of the high-voltage battery 120 and the SOC of the auxiliary battery 130 are both equal to or greater than the corresponding reference SOC, the controller 170 may be configured to operate the solar charging panel 110 to supply power to the high-voltage battery 120.

[0065] refer to Figure 6 , when the vehicle 1 is not started, even when the SOC of the high-voltage battery 120 is equal to or greater than a predetermined first reference SOC and the SOC of the auxiliary battery 130 is equal to or greater than a predetermined second reference SOC (d), when the SOC of the auxiliary battery 130 is equal to or less than the maximum SOC (a) and equal to or greater than a predetermined normal control lower limit SOC (b), the controller 170 can be configured to operate the solar charging panel 110 to supply the high-voltage battery 120 with the power generated by the solar charging panel 110 until the auxiliary battery 130 is discharged and the SOC of the auxiliary battery 130 reaches a predetermined first threshold SOC (c).

[0066] When the auxiliary battery 130 is discharged and the SOC of the auxiliary battery 130 reaches a predetermined first threshold SOC (c), the controller 170 may also be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130. When the auxiliary battery 130 is charged and the SOC of the auxiliary battery 130 reaches a maximum SOC (a), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high-voltage battery 120. When the auxiliary battery 130 is discharged again and the SOC of the auxiliary battery 130 reaches a predetermined normal control lower limit SOC (b), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130.

[0067] Specifically, the maximum SOC (a) may indicate the SOC when the auxiliary battery 130 is fully charged, the normal control lower limit SOC (b) may indicate the lower limit SOC of a stable state for providing the optimal power to the electric field load 190, and has a value equal to or greater than the reference SOC (d). The first threshold SOC (c) may indicate the SOC at a specific point that is equal to or less than the normal control lower limit SOC (b) and equal to or greater than the reference SOC (d), and the first threshold SOC (c) may indicate the SOC when the auxiliary battery 130 is discharged for a specific time after the start-up shutdown of the vehicle 1. The first threshold SOC may be preset in the design stage and may be stored in the storage 150.

[0068] The power supply that is preferentially generated to the high-voltage battery 120 until the SOC of the auxiliary battery 130 reaches the first threshold SOC (c) can charge the high-voltage battery 120, which enables the user of the vehicle 1 to recognize or view the SOC through the display 160, thereby setting the solar charging panel 110 to indicate that charging is being performed. Alternatively, when the SOC of the auxiliary battery 130 is less than a predetermined normal control lower limit SOC (b) and is equal to or greater than a second reference SOC (d), the controller 170 can be configured to operate the solar charging panel 110 to supply the auxiliary battery 130 with the power generated by the solar charging panel 110.

[0069] When the SOC of the auxiliary battery 130 is less than the normal control lower limit SOC (b), the high voltage battery 120 may be configured to charge the auxiliary battery 130 and fuel consumption may be reduced, and therefore, the power supply to the auxiliary battery 130 may be prioritized. When the auxiliary battery 130 is charged and the SOC of the auxiliary battery 130 reaches the maximum SOC (a), the controller 170 may be configured to operate the solar charging panel 110 to supply the high voltage battery 120 with the power generated by the solar charging panel 110.

[0070] When the auxiliary battery 130 is discharged again and the SOC of the auxiliary battery 130 reaches the predetermined normal control lower limit SOC (b), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130. When the vehicle 1 is not started, the power generated by the solar charging panel 110 may be supplied to the high-voltage battery 120 or the auxiliary battery 130 to charge the high-voltage battery 120 and the auxiliary battery 130. In other words, the high-voltage battery 120 and the auxiliary battery 130 may continue to be charged until the vehicle 1 is started.

[0071] Figure 8 and Fig. 9 Schematic diagram showing a case where the SOC of the high-voltage battery is less than the reference SOC and the SOC of the auxiliary battery is equal to or greater than the reference SOC according to an exemplary embodiment. When the vehicle 1 is not started, in the case where the SOC of the high-voltage battery 120 is less than a predetermined first reference SOC and the SOC of the auxiliary battery 130 is equal to or greater than a predetermined second reference SOC (d), the controller 170 may be configured to operate the solar charging panel 110 to supply the high-voltage battery 120 with the power generated by the solar charging panel 110.

[0072] When the SOC of the high-voltage battery 120 is lower than the first reference SOC, the vehicle 1 may charge the high-voltage battery 120 using electric energy generated by motor regeneration based on the surplus output of the engine of the vehicle 1. In other words, when the SOC of the high-voltage battery 120 is lower than the first reference SOC, idle charging corresponding to charging the high-voltage battery 120 using the engine during driving of the vehicle 1 may be performed, and therefore, the engine is always started even during parking of the vehicle 1, so that fuel efficiency may deteriorate.

[0073] Therefore, when the SOC of the high-voltage battery 120 is less than the predetermined first reference SOC, and the SOC of the auxiliary battery 130 is equal to or greater than the predetermined second reference SOC(d), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high-voltage battery 120. Specifically, reference Figure 8 When the vehicle 1 is not started, the controller 170 may be configured to operate the solar charging panel 110 to supply the high voltage battery 120 with electricity generated by the solar charging panel 110 .

[0074] At this time, when the auxiliary battery 130 is discharged and the SOC of the auxiliary battery 130 reaches the second reference SOC(d), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130. Therefore, the SOC of the auxiliary battery 130 may be prevented from falling below the second reference SOC(d), and the measurement of the remaining SOC of the auxiliary battery 130 may be prevented from being inaccurate, thereby protecting the auxiliary battery 130.

[0075] Even when the solar charging panel 110 is operated to supply the power generated by the solar charging panel 110 to the high-voltage battery 120, when the auxiliary battery 130 is discharged and the SOC of the auxiliary battery 130 reaches the second reference SOC(d), the controller 170 can be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130.

[0076] When the auxiliary battery 130 is charged and the SOC of the auxiliary battery 130 reaches the maximum SOC (a), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high voltage battery 120. When the auxiliary battery 130 is discharged again and the SOC of the auxiliary battery 130 reaches a predetermined normal control lower limit SOC (b), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130.

[0077] refer to Fig. 9 , when the high-voltage battery 120 is charged due to the power generated by the solar charging panel 110 being supplied to the high-voltage battery 120 and the SOC of the high-voltage battery 120 reaches the first reference SOC, the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130. In other words, even when the solar charging panel 110 is operated to supply the power generated by the solar charging panel 110 to the high-voltage battery 120, in the case where the high-voltage battery 120 is charged and the SOC of the high-voltage battery 120 reaches the first reference SOC, the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130.

[0078] When the auxiliary battery 130 is charged and the SOC of the auxiliary battery 130 reaches the maximum SOC (a), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high voltage battery 120. When the auxiliary battery 130 is discharged again and the SOC of the auxiliary battery 130 reaches the predetermined normal control lower limit SOC (b), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130. When the vehicle 1 is not started, the power generated by the solar charging panel 110 may be supplied to the high voltage battery 120 or the auxiliary battery 130 to charge the high voltage battery 120 and the auxiliary battery 130. In other words, the charging of the high voltage battery 120 and the auxiliary battery 130 may continue until the vehicle 1 is started.

[0079] Fig.10 2 is a diagram showing a case where the SOC of the high voltage battery is equal to or greater than the reference SOC and the SOC of the auxiliary battery is less than the reference SOC according to an exemplary embodiment. Fig.10 When the vehicle 1 is not started, when the SOC of the high-voltage battery 120 is equal to or greater than a predetermined first reference SOC and the SOC of the auxiliary battery 130 is less than a predetermined second reference SOC (d), the controller 170 can be configured to operate the solar charging panel 110 to supply the auxiliary battery 130 with power generated by the solar charging panel 110.

[0080] When the auxiliary battery 130 is charged and the SOC of the auxiliary battery 130 reaches the maximum SOC (a), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high voltage battery 120. When the auxiliary battery 130 is discharged again and the SOC of the auxiliary battery 130 reaches the predetermined normal control lower limit SOC (b), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated from the solar charging panel 110 to the auxiliary battery 130. When the vehicle 1 is not started, the power generated by the solar charging panel 110 may be supplied to the high voltage battery 120 or the auxiliary battery 130 to charge the high voltage battery 120 and the auxiliary battery 130. In other words, the high voltage battery 120 and the auxiliary battery 130 may continue to be charged until the vehicle 1 is started.

[0081] Fig.11 Schematic diagram showing a case where the SOC of the high voltage battery is less than the reference SOC and the SOC of the auxiliary battery is less than the reference SOC according to an exemplary embodiment. Fig.11When the vehicle 1 is not started, when the SOC of the high-voltage battery 120 is less than a predetermined first reference SOC, and the SOC of the auxiliary battery 130 is less than a predetermined second reference SOC(d), the controller 170 can be configured to operate the solar charging panel 110 to supply the auxiliary battery 130 with electricity generated by the solar charging panel 110.

[0082] In addition, when the auxiliary battery 130 is charged and the SOC of the auxiliary battery 130 reaches a predetermined second threshold SOC (e), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high voltage battery 120. The second threshold SOC (e) is a value preset in the design stage and stored in the storage 150, and may correspond to an SOC at a specific point that is equal to or greater than the second reference SOC (d) and equal to or less than the normal control lower limit SOC (b).

[0083] Specifically, even when the SOC of the high-voltage battery 120 is less than a predetermined first reference SOC and the SOC of the auxiliary battery 130 is less than a predetermined second reference SOC(d), when the auxiliary battery 130 is charged to a certain level (e.g., a second threshold SOC(e)), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high-voltage battery 120. In other words, when the SOC of the high-voltage battery 120 is lower than the first reference SOC, idle charging corresponding to charging the high-voltage battery 120 using the engine during driving of the vehicle 1 may be performed, and therefore, even during parking of the vehicle 1, the engine is always started, resulting in deterioration in fuel efficiency.

[0084] When the auxiliary battery 130 is discharged and the SOC of the auxiliary battery 130 reaches the second reference SOC (d), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130. As described above, as the auxiliary battery 130 may be charged and discharged and the SOC of the auxiliary battery 130 is repeatedly between the second reference SOC (d) and the second threshold SOC (e), the high voltage battery 120 may be charged and the SOC of the high voltage battery 120 may reach the first reference SOC.

[0085] In addition, when the high-voltage battery 120 is charged and the SOC of the high-voltage battery 120 reaches the first reference SOC, the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130. When the auxiliary battery 130 is charged and the SOC of the auxiliary battery 130 reaches the maximum SOC (a), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high-voltage battery 120. When the auxiliary battery 130 is discharged again and the SOC of the auxiliary battery 130 reaches a predetermined normal control lower limit SOC (b), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130.

[0086] When the vehicle 1 is not started, the power generated by the solar charging panel 110 may be supplied to the high-voltage battery 120 or the auxiliary battery 130 to charge the high-voltage battery 120 and the auxiliary battery 130. The high-voltage battery 120 and the auxiliary battery 130 may continue to be charged until the vehicle 1 is started. When the auxiliary battery 130 is charged and the SOC of the auxiliary battery 130 reaches the maximum SOC (a), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high-voltage battery 120. When the high-voltage battery 120 is charged and the SOC of the high-voltage battery 120 reaches the maximum SOC, the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130.

[0087] In addition, the vehicle 1 may further include a separate battery (not shown) configured to store the power generated by the solar charging panel 110. The controller 170 may be configured to operate the separate battery based on the SOC of the high-voltage battery 120 and the SOC of the auxiliary battery 130 when the vehicle 1 is not started, so as to supply the power stored in the separate battery to the high-voltage battery 120 or the auxiliary battery 130, respectively.

[0088] Hereinafter, a method for controlling the vehicle 1 according to an exemplary embodiment will be described. The method described below may be performed by a controller. The vehicle 1 according to the above exemplary embodiment may be applied to the method for controlling the vehicle 1 described later. Therefore, without particular mention, the above reference Figures 1 to 11 What has been described also applies to the method for controlling the vehicle 1 according to the exemplary embodiment.

[0089] Fig.12 1 is a flowchart showing a method for controlling a vehicle according to an exemplary embodiment in the case of determining whether electric power is generated by a solar charging panel. Fig.12, when the vehicle 1 is not started (“Yes” in 1210 ), the vehicle 1 may be configured to measure the amount of sunlight through the solar charging panel 110 ( 1220 ).

[0090] Specifically, the controller 170 of the vehicle 1 may be configured to calculate the power that can be generated by the solar charging panel 110 based on the measured amount of sunlight (1230). The controller 170 may be configured to calculate the generable power based on information indicating the relationship between the amount of sunlight stored in advance and the generable power that can be generated in the solar charging panel 110. The calculated generable power may refer to the power that can be generated by the solar charging panel 110 per unit time.

[0091] When the calculated reproducible power is equal to or greater than the power consumption during power generation ("Yes" in 1240), the vehicle 1 can be configured to generate power using the solar charging panel 110 (1250). Specifically, the controller 170 of the vehicle 1 can be configured to compare the calculated reproducible power with the stored power consumption during power generation, and when the calculated reproducible power is greater than the power consumption during power generation, the controller 170 of the vehicle 1 can be configured to operate the solar charging panel 110 to generate power.

[0092] In other words, when the calculated power that can be generated is greater than the power consumption during power generation, the controller 170 can be configured to operate the solar charging panel 110 to generate power. When the calculated power that can be generated is less than the power consumption during power generation, the controller 170 can also be configured to prevent the solar charging panel 110 from performing power generation. In this example, the power consumption consumed during power generation can correspond to the basic power consumption per unit time consumed when the solar charging panel 110 generates power, and can include the power consumption under the operation of the controller 170 and the power consumption according to the measurement of the battery sensor 140.

[0093] Fig.13 1 is a flow chart of a method for controlling a vehicle according to an exemplary embodiment when charging a battery through a solar charging panel. The method described below may be executed by a controller. Fig.13 When the vehicle 1 is not started, the controller 170 may be configured to determine the battery to be supplied by the power generated by the solar charging panel 110 based on the SOC of each of the high voltage battery 120 and the auxiliary battery 130 measured by the battery sensor 140 .

[0094] Specifically, when the SOC of the auxiliary battery 130 is equal to or greater than the reference SOC (“Yes” in 1310) and the SOC of the high voltage battery 120 is equal to or greater than the reference SOC (“Yes” in 1320), the controller 170 may be configured to operate the solar charging panel 110 to charge the auxiliary battery 130 (1330). In other words, when the SOC of the high voltage battery 120 and the SOC of the auxiliary battery 130 are both equal to or greater than the corresponding reference SOC, the controller 170 may be configured to operate the solar charging panel 110 to preferentially supply power to the auxiliary battery 130.

[0095] However, even when the SOC of the high-voltage battery 120 and the SOC of the auxiliary battery 130 are both equal to or greater than the corresponding reference SOC, the controller 170 may be configured to operate the solar charging panel 110 to preferentially supply power to the high-voltage battery 120. When the vehicle 1 is not started, even when the SOC of the high-voltage battery 120 is equal to or greater than the predetermined first reference SOC and the SOC of the auxiliary battery 130 is equal to or greater than the predetermined second reference SOC (d), in the case where the SOC of the auxiliary battery 130 is equal to or less than the maximum SOC (a) and equal to or greater than the predetermined normal control lower limit SOC (b), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high-voltage battery 120 until the auxiliary battery 130 is discharged and the SOC of the auxiliary battery 130 reaches the predetermined first threshold SOC (c).

[0096] When the auxiliary battery 130 is discharged and the SOC of the auxiliary battery 130 reaches a predetermined first threshold SOC (c), the controller 170 may also be configured to operate the solar charging panel 110 to supply the auxiliary battery 130 with the power generated by the solar charging panel 110. Alternatively, when the SOC of the auxiliary battery 130 is less than a predetermined normal control lower limit SOC (b) and is equal to or greater than a second reference SOC (d), the controller 170 may be configured to operate the solar charging panel 110 to supply the auxiliary battery 130 with the power generated by the solar charging panel 110.

[0097] When the auxiliary battery 130 is charged and the SOC of the auxiliary battery 130 reaches the maximum SOC (a), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high voltage battery 120. When the auxiliary battery 130 is discharged again and the SOC of the auxiliary battery 130 reaches a predetermined normal control lower limit SOC (b), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130.

[0098] When the vehicle 1 is not started, the power generated by the solar charging panel 110 can be supplied to the high-voltage battery 120 or the auxiliary battery 130 to charge the high-voltage battery 120 and the auxiliary battery 130. The high-voltage battery 120 and the auxiliary battery 130 can continue to be charged until the vehicle 1 is started ("Yes" in 1350). When the vehicle 1 is not started, if the SOC of the auxiliary battery 130 is equal to or greater than the reference SOC ("Yes" in 1310) and the SOC of the high-voltage battery 120 is less than the reference SOC ("No" in 1320), the controller 170 can also be configured to operate the solar charging panel 110 to charge the high-voltage battery 120 (1340).

[0099] In other words, when the SOC of the high-voltage battery 120 is less than a predetermined first reference SOC and the SOC of the auxiliary battery 130 is equal to or greater than a predetermined second reference SOC(d), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high-voltage battery 120. When the auxiliary battery 130 is discharged and the SOC of the auxiliary battery 130 reaches the second reference SOC(d), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130.

[0100] Even when the solar charging panel 110 is operated to supply the power generated by the solar charging panel 110 to the high-voltage battery 120, when the auxiliary battery 130 is discharged and the SOC of the auxiliary battery 130 reaches the second reference SOC (d), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130. When the high-voltage battery 120 is charged due to the supply of the power generated by the solar charging panel 110 to the high-voltage battery 120 and the SOC of the high-voltage battery 120 reaches the first reference SOC, the controller 170 may also be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130.

[0101] In addition, even when the solar charging panel 110 is operated to supply the power generated by the solar charging panel 110 to the high voltage battery 120, in the case where the high voltage battery 120 is charged and the SOC of the high voltage battery 120 reaches the first reference SOC, the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130. When the auxiliary battery 130 is charged and the SOC of the auxiliary battery 130 reaches the maximum SOC (a), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high voltage battery 120. When the auxiliary battery 130 is discharged again and the SOC of the auxiliary battery 130 reaches the predetermined normal control lower limit SOC (b), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130.

[0102] When the vehicle 1 is not started, the power generated by the solar charging panel 110 can be supplied to the high-voltage battery 120 or the auxiliary battery 130 to charge the high-voltage battery 120 and the auxiliary battery 130. When the vehicle 1 is started ("Yes" in 1350), the charging of the high-voltage battery 120 and the auxiliary battery 130 can be completed. When the vehicle 1 is not started, if the SOC of the auxiliary battery 130 is less than the reference SOC ("No" in 1310), the controller 170 can also be configured to operate the solar charging panel 110 to charge the auxiliary battery 130 (1330).

[0103] Specifically, when the vehicle 1 is not started, in the case where the SOC of the high-voltage battery 120 is equal to or greater than the first reference SOC and the SOC of the auxiliary battery 130 is less than the second reference SOC (d), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130. When the auxiliary battery 130 is charged and the SOC of the auxiliary battery 130 reaches the maximum SOC (a), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high-voltage battery 120. In addition, when the auxiliary battery 130 is discharged again and the SOC of the auxiliary battery 130 reaches a predetermined normal control lower limit SOC (b), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130.

[0104] When the vehicle 1 is not started, the power generated by the solar charging panel 110 may be supplied to the high voltage battery 120 or the auxiliary battery 130 to charge the high voltage battery 120 and the auxiliary battery 130. The high voltage battery 120 and the auxiliary battery 130 may continue to be charged until the vehicle 1 is started (“Yes” in 1350). When the vehicle 1 is not started, in the case where the SOC of the auxiliary battery 130 is less than the first reference SOC and the SOC of the high voltage battery 120 is less than the second reference SOC, the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130.

[0105] When the auxiliary battery 130 is charged and the SOC of the auxiliary battery 130 reaches a predetermined second threshold SOC (e), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high voltage battery 120. The second threshold SOC (e) is a value preset in the design stage and stored in the storage 150, and may correspond to an SOC at a specific point that is equal to or greater than the second reference SOC (d) and equal to or less than the normal control lower limit SOC (b).

[0106] Even in a state where the SOC of the high-voltage battery 120 is less than a predetermined first reference SOC and the SOC of the auxiliary battery 130 is less than a predetermined second reference SOC(d), when the auxiliary battery 130 is charged to a certain level (e.g., a second threshold SOC(e)), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high-voltage battery 120. When the auxiliary battery 130 is discharged and the SOC of the auxiliary battery 130 reaches the second reference SOC(d), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130.

[0107] As described above, as the auxiliary battery 130 is charged and discharged and the SOC of the auxiliary battery 130 is repeated between the second reference SOC (d) and the second threshold SOC (e), the high voltage battery 120 may be charged and the SOC of the high voltage battery 120 may reach the first reference SOC. When the high voltage battery 120 is charged and the SOC of the high voltage battery 120 reaches the first reference SOC, the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130. When the auxiliary battery 130 is charged and the SOC of the auxiliary battery 130 reaches the maximum SOC (a), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the high voltage battery 120.

[0108] Further, when the auxiliary battery 130 is discharged again and the SOC of the auxiliary battery 130 reaches a predetermined normal control lower limit SOC (b), the controller 170 may be configured to operate the solar charging panel 110 to supply the power generated by the solar charging panel 110 to the auxiliary battery 130. When the vehicle 1 is not started, the power generated by the solar charging panel 110 may be supplied to the high-voltage battery 120 or the auxiliary battery 130 to charge the high-voltage battery 120 and the auxiliary battery 130. When the vehicle 1 is started ("Yes" in 1350), the charging of the high-voltage battery 120 and the auxiliary battery 130 may be completed.
