[0046] In the following, embodiments of the vehicle and its control method according to the accompanying drawings will be described in detail.

[0047] Figure 1 This is a control block diagram of a vehicle according to an embodiment of the present disclosure. Figure 2 This is a view illustrating the electrical flow of a vehicle according to an embodiment of the present disclosure.

[0048] Reference Figure 1According to an embodiment, the vehicle 10 includes: a battery 115; a battery sensor 110 for detecting the charging state of the battery 115; a driving detection sensor 120 for detecting the driving state of the vehicle 10; an illuminance sensor 130 for detecting illuminance; a temperature sensor 140 for detecting temperature; and a controller 150 for determining whether a generator 190 is installed on the vehicle 10 (see [link to controller]). Figure 2 The vehicle 10 includes a power supply device 160 for supplying charging power to the battery 115, a power load 170 for performing various functions of the vehicle 10, and a storage device 180 for storing various information required by the vehicle 10. However, according to an embodiment, each component of the vehicle 10 may be omitted.

[0049] According to the embodiment, the battery sensor 110 can detect the charging state of the battery 115. Specifically, the battery sensor 110 can detect the charging amount of the battery 115 in real time.

[0050] Therefore, the battery sensor 110 may include a voltage sensor capable of detecting the voltage of the battery 115, a current sensor capable of detecting the current of the battery 115, and a temperature sensor capable of detecting the temperature of the battery 115.

[0051] As described above, the battery sensor 110 can detect the state of charge (SOC) of the battery 115 in real time based on at least one of the voltage, current and temperature of the battery 115.

[0052] At this time, battery 115 is an energy storage device capable of supplying IGN power for starting vehicle 10 or supplying power to electrical load 170 for performing various functions of vehicle 10, and can be a lead-acid battery or a lithium-ion battery. However, the type and number of batteries 115 are not limited.

[0053] According to the embodiment, the driving detection sensor 120 can detect the driving status of the vehicle 10. Specifically, the driving detection sensor 120 can detect whether the vehicle 10 is moving or parked.

[0054] Therefore, the driving detection sensor 120 can be an acceleration sensor that measures the acceleration of the vehicle 10, or a voltage sensor or a current sensor that detects the IGN power supply.

[0055] The illuminance sensor 130 according to the embodiment can detect the illuminance in the space where the vehicle 10 is located. Specifically, the illuminance sensor 130 can detect the illuminance based on the amount of sunlight in the space where the vehicle 10 is located. An illuminance sensor of a known type can be used as the illuminance sensor 130.

[0056] The temperature sensor 140 according to the embodiment can detect the temperature of the air outside the vehicle 10. For this purpose, a temperature sensor of a previously known type can be used as the temperature sensor 140.

[0057] According to an embodiment, the controller 150 can determine whether a power generation device 190 is installed on the vehicle 10. That is, the controller 150 can determine whether a power generation device 190 is installed based on the charging state of the battery 115.

[0058] Specifically, the controller 150 determines whether the vehicle 10 is parked based on the output of the driving detection sensor 120, and when the vehicle 10 is parked and the battery 115 is being charged, the controller 150 determines that the power generation device 190 is installed.

[0059] like Figure 2 As shown, when the vehicle 10 is in motion, the battery 115 can be charged via the power supply device 160. That is, when there is no power generation device 190 for energy harvesting, the battery 115 cannot be charged while the vehicle is parked.

[0060] The controller 150 determines that the power generation device 190 is installed when the battery 115 is being charged during parking, based on the point that the power generation device 190 is being charged during parking.

[0061] At this time, the power generation device 190 is a device capable of generating electricity using natural energy. For example, the power generation device 190 may include a solar panel that converts solar energy into electrical energy, a thermoelectric element that regenerates electrical energy from engine waste heat, and an electromagnetic induction device that regenerates electrical energy from the reciprocating motion of a suspension shock absorber. In the following description, for ease of description, the power generation device 190 will be described as a solar panel, but the type of power generation device 190 is not limited to this.

[0062] However, the controller 150 may further consider the output of the illuminance sensor 130 or various switches to exclude the case of charging via an external charger.

[0063] Specifically, when the output of the illuminance sensor 130 determines that the power generation device 190 cannot generate electricity using the current illuminance, the controller 150 determines that charging is performed through an external charger. That is, when the output of the illuminance sensor 130 is equal to or less than a preset value, the controller 150 may not determine whether the power generation device 190 is installed.

[0064] Additionally, the controller 150 determines whether charging is via an external charger based on whether a switch corresponding to each of the hood, trunk, and doors where the battery 115 can be located is operated. That is, based on whether a switch is operated, the controller 150 may not determine whether the generator 190 is installed when any of the hood, trunk, and doors where the battery 115 can be located are open.

[0065] The controller 150 can determine that the power generation device 190 is installed based on user input from the input device of the vehicle 10, and can also determine that the power generation device 190 is installed based on the voltage or current of the battery 115 in the output of the battery sensor 110.

[0066] According to the embodiment, the controller 150 can control the overcharging of the battery 115 when the vehicle 10 is parked and the battery 115 is fully charged.

[0067] Specifically, when the vehicle 10 is parked and the battery 115 is being charged by the generator 190, the controller 150 can determine that the battery 115 is fully charged based on the output of the battery sensor 110.

[0068] At this time, the controller 150 can control the battery 115 to prevent overcharging when the battery 115 is fully charged, thereby improving the durability of the battery 115.

[0069] For example, controller 150 can control the switch between battery 115 and generator 190 to prevent overcharging of battery 115. That is, controller 150 can control the switch to disconnect battery 115 and generator 190.

[0070] Additionally, the controller 150 determines the electrical load 170 based on at least one of the illuminance detected by the illuminance sensor 130 and the external temperature detected by the temperature sensor 140, and as follows: Figure 2 As shown, the battery 115 can be controlled to supply power to the electrical load 170 to prevent the battery 115 from being overcharged.

[0071] For example, when the outside temperature is high, the controller 150 identifies the air conditioning unit in the power load 170 and controls the battery 115 to supply power to the air conditioning unit to prevent the battery 115 from being overcharged.

[0072] Additionally, when the external temperature is low, the controller 150 identifies the seat heating wire in the electrical load 170 and controls the battery 115 to supply power to the seat heating wire to prevent overcharging of the battery 115.

[0073] When the vehicle 10 is parked and the battery 115 is being charged, the controller 150 according to the embodiment can determine the hourly power generation of the power generation device 190 and can adjust the target charging amount of the battery 115 in a direction that decreases proportionally to the hourly power generation of the power generation device 190.

[0074] At this time, the controller 150 can determine the hourly power generation based on at least one of illuminance and external temperature and store the hourly power generation.

[0075] Additionally, the controller 150 can determine the adjustment amount of the target charging amount of the battery 115 based on at least one of illuminance and external temperature. That is, when the amount of light, represented by illuminance, is high or the external temperature is high, the controller 150 can determine the amount by which the target charging amount is reduced.

[0076] Therefore, when the vehicle 10 is in motion, the controller 150 can control the power supply device 160 based on the adjusted charging target amount. Specifically, the controller 150 can control the power supply device 160 to adjust the output voltage for charging the battery 115 in response to the adjusted charging target amount of the battery 115, or it can control the power supply device 160 so that it stops charging the battery 115 when the adjusted charging target amount is reached.

[0077] As described above, when a generator 190 is installed on the vehicle 10, the vehicle 10 can reduce the amount of charging of the battery 115 by the power supply device 160 when driving by considering charging the battery 115 through the generator 190 when parked, thereby improving the driving efficiency and power efficiency of the vehicle 10.

[0078] The controller 150 may include at least one memory for storing programs for performing the operations described above and below, and at least one processor for executing the stored programs. In the case of multiple memories and processors, the multiple memories and processors may be integrated into a single chip or located in physically separate locations.

[0079] According to the embodiment, the power supply device 160 can supply charging power to the battery 115. That is, the power supply device 160 can adjust the output voltage for charging the battery 115 under the control of the controller 150, or stop charging the battery 115.

[0080] The power supply device 160 may correspond to an alternator that generates electricity based on the rotational force of the engine. That is, the power supply device 160 may be an alternator that supplies charging power to the battery 115 based on the rotational force of the engine. A known alternator may be used as this alternator.

[0081] Additionally, when vehicle 10 corresponds to an environmentally friendly vehicle that uses electrical energy, such as a hybrid vehicle including a motor that provides power, or an electric vehicle, the power supply unit 160 can be a converter that supplies charging power to battery 115 by converting the high-voltage power from the main battery that supplies high-voltage power to the motor into low-voltage power. Known converters can be used as this converter.

[0082] According to the embodiment, the power load 170 can receive power from the battery 115 under the control of the controller 150.

[0083] At this time, the electrical load 170 corresponds to the electrical equipment that performs various functions of the vehicle 10, and may include the vehicle 10's lights, air conditioning unit, heating wire, black box device, and window adjustment device. In addition, it may include, but is not limited to, any electrical equipment capable of performing various functions of the vehicle 10.

[0084] The storage device 180 according to the embodiment can store various information required to control the vehicle 10. For example, the storage device 180 can store the hourly power generation of the power generation device 190 obtained during parking. At this time, the storage device 180 can store the hourly power generation based on at least one of illuminance and external temperature. For this purpose, a known storage medium or the like can be used as the storage device 180.

[0085] Figure 3 This is a view showing the vehicle 10 being charged by the power generation device 190 when it is parked according to an embodiment of the present disclosure.

[0086] Reference Figure 3 According to the embodiment, the charge level of the battery 115 in the vehicle 10 when it is parked and the charge level of the battery 115 after it has been parked may be different. For example, the battery 115 may show an 85% charge level when parked, while after parking it may show a charge level of 86% or higher.

[0087] According to an embodiment, the controller 150 can determine whether a power generation device 190 is installed on the vehicle 10. That is, the controller 150 can determine whether a power generation device 190 is installed based on the charging state of the battery 115.

[0088] Specifically, the controller 150 determines whether the vehicle 10 is parked based on the output of the driving detection sensor 120, and when the vehicle 10 is parked and the battery 115 is being charged, the controller 150 can determine that the generator 190 is installed.

[0089] When the vehicle 10 is in motion, the battery 115 can be charged via the power supply device 160. That is, if there is no power generation device 190 for energy harvesting, the battery 115 cannot be charged while the vehicle is parked.

[0090] The controller 150 determines that the power generation device 190 is installed when the battery 115 is being charged during parking, based on the point that the power generation device 190 is being charged during parking.

[0091] Therefore, as Figure 3 As shown, when the charge of battery 115 increases after parking, controller 150 can determine that a generator 190 is installed on vehicle 10.

[0092] However, the controller 150 may further consider the output of the illuminance sensor 130 or various switches to exclude the case of charging via an external charger.

[0093] Specifically, when the output of the illuminance sensor 130 determines that the power generation device 190 cannot generate electricity using the current illuminance, the controller 150 determines that charging is performed through an external charger. That is, when the output of the illuminance sensor 130 is equal to or less than a preset value, the controller 150 may not determine whether the power generation device 190 is installed.

[0094] Additionally, the controller 150 determines whether charging is via an external charger based on whether a switch corresponding to each of the hood, trunk, and doors where the battery 115 can be located is operated. That is, based on whether a switch is operated, the controller 150 may not determine whether the generator 190 is installed when any of the hood, trunk, and doors where the battery 115 can be located are open.

[0095] The controller 150 can determine that the power generation device 190 is installed based on user input from the input device of the vehicle 10, and can also determine that the power generation device 190 is installed based on the voltage or current of the battery 115 in the output of the battery sensor 110.

[0096] According to the embodiment, the controller 150 can control the overcharging of the battery 115 when the vehicle 10 is parked and the battery 115 is fully charged.

[0097] Specifically, when the vehicle 10 is parked and the battery 115 is being charged by the generator 190, the controller 150 can determine that the battery 115 is fully charged based on the output of the battery sensor 110.

[0098] At this time, the controller 150 can control the battery 115 to prevent overcharging when the battery 115 is fully charged, thereby improving the durability of the battery 115.

[0099] For example, controller 150 can control the switch between battery 115 and generator 190 to prevent overcharging of battery 115. That is, controller 150 can control the switch to disconnect battery 115 and generator 190.

[0100] Additionally, the controller 150 determines the electrical load 170 based on at least one of the illuminance detected by the illuminance sensor 130 and the external temperature detected by the temperature sensor 140, and can control the battery 115 to supply power to the electrical load 170 to prevent overcharging of the battery 115.

[0101] For example, when the outside temperature is high, the controller 150 identifies the air conditioning unit in the power load 170 and controls the battery 115 to supply power to the air conditioning unit to prevent the battery 115 from being overcharged.

[0102] Additionally, when the external temperature is low, the controller 150 identifies the seat heating wire in the electrical load 170 and controls the battery 115 to supply power to the seat heating wire to prevent overcharging of the battery 115.

[0103] In addition, such as Figure 3 As shown, when the vehicle 10 is parked and the battery 115 is being charged, the controller 150 according to the embodiment can determine the hourly power generation of the power generation device 190 and can adjust the target charging amount of the battery 115 in a direction that decreases proportionally to the hourly power generation of the power generation device 190.

[0104] For example, controller 150 can determine an adjusted charging target amount by subtracting the hourly power generation multiplied by a conversion factor from a preset basic charging target amount. In this case, the conversion factor can correspond to the efficiency coefficient during driving and can be a value reflecting information about the relationship between the charging target amount and driving efficiency.

[0105] At this time, the controller 150 can determine the hourly power generation based on at least one of illuminance and external temperature and store the hourly power generation in the storage device 180.

[0106] Additionally, the controller 150 can determine the adjustment amount of the target charging amount of the battery 115 based on at least one of illuminance and external temperature. That is, when the amount of light, represented by illuminance, is high or the external temperature is high, the controller 150 can determine the amount by which the target charging amount is reduced.

[0107] Therefore, when the vehicle 10 is in motion, the controller 150 can control the power supply device 160 based on the adjusted charging target amount. Specifically, the controller 150 can control the power supply device 160 to adjust the output voltage for charging the battery 115 in response to the adjusted charging target amount of the battery 115, or it can control the power supply device 160 so that it stops charging the battery 115 when the adjusted charging target amount is reached.

[0108] That is, when driving, the controller 150 can determine an adjusted charging target amount corresponding to at least one of the current illuminance and the external temperature from the adjusted charging target amount stored in the storage device 180, and control the power supply device 160 based on the determined charging target amount.

[0109] As described above, when a generator 190 is installed on the vehicle 10, the vehicle 10 can reduce the amount of charging of the battery 115 by the power supply device 160 when driving by considering charging the battery 115 through the generator 190 when parked, thereby improving the driving efficiency and power efficiency of the vehicle 10.

[0110] Hereinafter, a control method for a vehicle 10 according to an embodiment will be described. The vehicle 10 according to the above embodiment can be applied to the control method for the vehicle 10 described later. Therefore, even if not specifically mentioned, reference will be made to... Figures 1 to 3 The description also applies to the control method of vehicle 10 according to the embodiment.

[0111] Figure 4 This is a flowchart illustrating a method for determining whether a vehicle 10 is equipped with a power generation device in a control method for a vehicle 10 according to an embodiment of the present disclosure.

[0112] Reference Figure 4 According to the embodiment, the vehicle 10 can determine whether to stop based on the output of the driving detection sensor 120 (410), and when the vehicle 10 stops ("yes" in 420), the vehicle 10 according to the embodiment can determine whether the battery 115 is being charged based on the output of the battery sensor 110 (430).

[0113] When the battery 115 is charging ("Yes" in 440), the vehicle 10 according to the embodiment can determine whether the battery 115 is being charged by an external charger based on the output of at least one of the illuminance sensor 130 and the hood switch (450). When the battery 115 is not being charged by an external charger ("No" in 460), the vehicle 10 according to the embodiment can determine that a power generation device 190 is installed (470).

[0114] That is, vehicle 10 can determine whether a generator 190 is installed based on the state of charge of battery 115. However, vehicle 10 can further consider the output of illuminance sensor 130 or various switches to rule out the possibility of charging via an external charger.

[0115] Vehicle 10 can determine that a power generation device 190 is installed based on user input from the input device of vehicle 10, and can also determine that a power generation device 190 is installed based on the voltage or current of battery 115 in the output of battery sensor 110.

[0116] Figure 5 This is a flowchart illustrating a control method for a vehicle 10 according to an embodiment of the present disclosure, whereby the vehicle 10 prevents the battery 115 from overcharging.

[0117] Reference Figure 5When the vehicle is parked ("Yes" in 510), the vehicle 10 according to the embodiment can determine whether the battery 115 is fully charged by the power generation device 190 based on the output of the battery sensor 110 (520).

[0118] When the battery 115 is fully charged ("Yes" in 530), the vehicle 10 according to the embodiment can prevent the battery 115 from being overcharged (540).

[0119] For example, vehicle 10 can control the switch between battery 115 and generator 190 to prevent overcharging of battery 115. That is, vehicle 10 can control the switch to disconnect battery 115 from generator 190.

[0120] In addition, the vehicle 10 determines the electrical load 170 based on at least one of the illuminance detected by the illuminance sensor 130 and the external temperature detected by the temperature sensor 140, and can control the battery 115 to supply power to the electrical load 170 to prevent overcharging of the battery 115.

[0121] For example, when the outside temperature is high, the controller 150 identifies the air conditioning unit in the power load 170 and controls the battery 115 to supply power to the air conditioning unit to prevent the battery 115 from being overcharged.

[0122] In addition, when the outside temperature is low, the vehicle 10 identifies the seat heating wire in the electrical load 170 and controls the battery 115 to supply power to the seat heating wire to prevent the battery 115 from being overcharged.

[0123] As described above, the vehicle 10 can be controlled to prevent overcharging of the battery 115 when it is fully charged, thereby improving the durability of the battery 115.

[0124] Figure 6 This is a flowchart illustrating the situation where the vehicle 10 adjusts the target charging amount of the battery 115 in a control method for a vehicle 10 according to an embodiment of the present disclosure.

[0125] Reference Figure 6 When the vehicle 10 is parked ("Yes" in 610), the vehicle 10 according to the embodiment can determine the hourly power generation of the power generation device 190 based on the output of the battery sensor 110 (620), and can adjust the target charging amount of the battery 115 in a direction that is proportional to the hourly power generation of the power generation device 190 (630).

[0126] At this time, vehicle 10 can determine and store the hourly power generation based on at least one of illuminance and external temperature.

[0127] Additionally, vehicle 10 can determine the adjustment amount of the target charging amount of battery 115 based on at least one of illuminance and external temperature. That is, when the amount of light, expressed by illuminance, is high or the external temperature is high, vehicle 10 can determine the amount by which the target charging amount is reduced.

[0128] When the vehicle 10 is in motion ("yes" in 640), the vehicle 10 can control the power supply device 160 (650) based on the adjusted charging target amount.

[0129] Specifically, the vehicle 10 can control the power supply device 160 to adjust the output voltage for charging the battery 115 in response to the adjusted charging target amount of the battery 115, or it can control the power supply device 160 so that the battery 115 is no longer charged when the adjusted charging target amount is reached.

[0130] As described above, when a generator 190 is installed on the vehicle 10, the vehicle 10 can reduce the amount of charging of the battery 115 by the power supply device 160 when driving by considering charging the battery 115 through the generator 190 when parked, thereby improving the driving efficiency and power efficiency of the vehicle 10.

[0131] According to the vehicle and control method of the present disclosure, by determining whether a power generation device for energy harvesting is installed and controlling the battery charging amount, the reduced battery durability caused by overcharging can be improved and the vehicle's power efficiency can be increased.

[0132] Computer-readable recording media can include all types of recording media that store instructions that can be executed by a computer. For example, computer-readable recording media can be ROM, RAM, magnetic tape, magnetic disk, flash memory, optical data storage devices, etc.

[0133] Exemplary embodiments of this disclosure have been described above with reference to the accompanying drawings. It will be apparent to those skilled in the art that this disclosure may be implemented in other forms different from the exemplary embodiments described above without altering the technical concept or essential characteristics of this disclosure. The above exemplary embodiments are merely illustrative and should not be interpreted in a limiting sense.
