[0080] Various components of the vehicle (1) have been described above. Below, with reference to FIGS. 3 to 6, a control method of the vehicle (1) utilizing the components of the vehicle (1) described above will be explained.

[0081] FIG. 3 is a flowchart relating to a vehicle control method according to one embodiment.

[0082] Referring to FIG. 3, the control unit (100) can calculate the angle of incidence of direct sunlight (DL) on the windshield (10) based on the position of the vehicle (1), the heading direction (HD) of the vehicle (1), the pitch angle of the vehicle (1), and the position of the sun (1000).

[0083] In one embodiment, the control unit (100) may receive position information, heading direction information, and pitch angle information of the vehicle (1) from the sensor unit (50). As another example, the control unit (100) may receive heading direction information, position information, and pitch angle information of the vehicle (1) from the navigation device (80).

[0084] In addition, the control unit (100) can determine the position of the sun based on time information and coordinate information corresponding to the position of the vehicle (1).

[0085] The method for determining the position of the sun may adopt a conventional method for calculating the position of the sun. That is, various programs capable of calculating the position of the sun when the current location and current time are input may be stored in the memory of the control unit (100). As another example, the control unit (100) may receive the position of the sun from an external device (e.g., a weather server) through the communication unit (70).

[0086] The position information of the sun may include information regarding the sun's azimuth, altitude, right ascension, and declination.

[0087] The control unit (100) can calculate the minimum angle of incidence of direct sunlight (DL) on the windshield (10) based on the position information of the sun, the position of the vehicle (1), the heading direction (HD), and the pitch angle.

[0088] For example, the control unit (100) can calculate the angle between the straight line connecting the position of the sun and the position of the vehicle (1) and the ground, and calculate the angle of incidence of direct sunlight (DL) on the windshield (10) based on the calculated angle and the pitch angle of the vehicle (1). At this time, the control unit (100) can determine whether the direct sunlight (DL) is incident on the windshield (10) in the front by considering the heading direction (HD) of the vehicle (1).

[0089] The control unit (100) can control the suspension (200) based on the angle of incidence of direct sunlight (DL) on the windshield (10).

[0090] In one embodiment, the control unit (100) can control the suspension (200) by adjusting at least one of the front garage or the rear garage so that the angle of incidence of direct light (DL) is greater than or equal to a preset angle.

[0091] At this time, the preset angle can be set based on the upper angle from the front end of the headliner, which is associated with forward and upward visibility, to the driver's eye position.

[0092] That is, the preset angle can be set based on the angle at which direct light (DL) reaches the driver's eyes.

[0093] FIG. 4 illustrates the case where the angle of incidence of sunlight on the windshield is greater than or equal to a preset angle.

[0094] Referring to FIG. 4, when the angle of incidence (θ1) of direct light (DL) on the windshield (10) is greater than a preset angle, the forward and upward visibility is compromised, and the direct light (DL) does not reach the driver's eyes. Accordingly, there is no need to adjust the ride height to prevent glare for the driver.

[0095] That is, the control unit (100) can control the suspension (200) so that the front height and rear height become default heights. At this time, the default height may refer to the front height and rear height of the vehicle (1) designed by default, and this may be stored in the memory of the control unit (100).

[0096] According to various embodiments, the control unit (100) can control the suspension (200) so that the front and rear ride heights become equal when the angle of incidence of direct light (DL) is greater than or equal to a preset angle (e.g., 1100). That is, the control unit (100) can control the suspension (200) so that there is no difference between the front and rear ride heights when the angle of incidence of direct light (DL) is greater than or equal to a preset angle, and if there is already no difference between the front and rear ride heights, the ride height can be maintained by keeping the state of the valve connecting the air spring and the reservoir in a closed state.

[0097] The control unit (100) can control the suspension (200) so that the rear ride height is higher than the front ride height (1400) if the angle of incidence of direct light (DL) is smaller than a preset angle (1100 No).

[0098] Figure 5 illustrates a case where the angle of incidence of sunlight on the windshield is smaller than a preset angle.

[0099] Referring to FIG. 5, when the angle of incidence (θ2) of direct light (DL) on the windshield (10) is smaller than a preset angle, direct light (DL) reaches the driver's eyes within the forward-upward visibility range. Accordingly, it is necessary to adjust the ride height to prevent glare for the driver.

[0100] The control unit (100) can control the suspension (200) so that the rear ride height is higher than the front ride height (1400) if the angle of incidence of direct light (DL) is smaller than a preset angle (1100 No).

[0101] That is, the control unit (100) can control the suspension (200) such that if the angle of incidence of direct light (DL) is smaller than a preset angle, the front height is lowered, the rear height is raised, or the front height is lowered and the rear height is raised. For example, the control unit (100) can control the supply valve connecting the air spring of the rear suspension (200R) and the reservoir to be open to provide compressed air to the rear air spring, or control the discharge valve connecting the air spring of the front suspension (200F) and the reservoir to be open to provide air from the front air spring to the reservoir.

[0102] The control unit (100) can determine how much the difference between the rear height and the front height should be maintained based on the angle of incidence of direct light (DL).

[0103] For example, the control unit (100) can calculate an angle (α) based on the difference between the front and rear ride heights according to the difference value (RH-FH) between the front ride height and the rear ride height with respect to the length (BL) of the vehicle body, and can control the suspension (200) such that the sum of the angle of incidence (θ2) of direct light (DL) and the angle (α) based on the difference value (RH-FH) is greater than or equal to a preset angle.

[0104] According to a vehicle (1) according to one embodiment, direct sunlight (DL) can be prevented from entering the driver's eyes, thereby preventing glare for the driver.

[0105] According to various embodiments, the control unit (100) may receive information about the predicted path of the vehicle (1) from the navigation device (80), calculate the angle of incidence of direct light (DL) on the predicted path, determine a predicted section where the angle of incidence of direct light (DL) on the predicted path is calculated to be smaller than a preset angle, and control the suspension (200) so that the rear ride height is higher than the front ride height before the vehicle (1) enters the predicted section.

[0106] For example, the control unit (100) can control the suspension (200) to pre-adjust the ride height of the vehicle (1) if the distance to the section where direct sunlight (DL) enters the driver's eyes is less than or equal to a preset distance.

[0107] According to a vehicle (1) according to one embodiment, the vehicle (1) can be adjusted to a state where direct sunlight (DL) can be blocked in advance before direct sunlight (DL) enters the driver's eyes, thereby providing convenience to the driver.

[0108] Meanwhile, the control unit (100) can maintain the garage in special cases even if the angle of incidence of direct sunlight (DL), determined based on the position of the sun and the position of the vehicle (1), the heading direction (HD), and the pitch angle, is smaller than a preset angle (No of 1100), that is, even if it is estimated that direct sunlight (DL) will enter the driver's eyes.

[0109] FIG. 6 illustrates a vehicle according to one embodiment passing through an area where a shadow is formed by terrain features.

[0110] Referring to Fig. 6, it can be seen that a shadow area (SA) is formed on the road where the vehicle (1) is traveling due to a terrain feature (e.g., a building).

[0111] According to various embodiments, the control unit (100) determines the shadow area (SA) of the road on which the vehicle (1) is traveling based on map information of the road on which the vehicle (1) is traveling and the position of the sun, and when it is determined that the vehicle (1) is traveling in the shadow area (SA) (e.g. 1300), the suspension (200) can be controlled so that the front and rear ride heights become default heights (1200).

[0112] For example, the control unit (100) can estimate the shadow area (SA) based on the location information and height information of terrain features included in the map information and the location information of the sun.

[0113] The control unit (100) can control the suspension (200) so that when the vehicle (1) enters the shadow area (SA) while the rear height is higher than the front height, the difference between the rear height and the front height becomes smaller.

[0114] As another example, the control unit (100) can control the suspension (200) so that the front and rear ride heights do not change even if the angle of incidence of direct light (DL) is smaller than a preset angle when the vehicle (1) is driving in a shadow area (SA) with the rear ride height at the default height of the front ride height.

[0115] According to a vehicle (1) according to one embodiment, even in a situation where direct sunlight (DL) may enter the driver's eyes due to the position of the sun and the position of the vehicle (1), if there is no concern that direct sunlight (DL) will enter the driver's eyes due to surrounding terrain features, the vehicle height can be maintained at a default height to ensure the driver's sense of stability.

[0116] According to various embodiments, the control unit (100) can control the suspension (200) so that the front and rear ride heights are at default heights even if the angle of incidence of direct sunlight (DL) is smaller than the angle of incidence of the direct sunlight (DL), in situations where there is no need to adjust the ride height, such as when rain is detected by a rain sensor, when rain is predicted according to weather information received from a communication unit (70), or when an illuminance level below a preset value is detected by an illuminance sensor.

[0117] According to the vehicle (1) according to one embodiment, unnecessary garage adjustment can be minimized.

[0118] According to various embodiments, the control unit (100) can control the suspension (200) so that the rear ride height is higher than the front ride height based on user input received through the input unit (60).

[0119] For example, the input unit (60) may include a function button for selecting a "direct light blocking function," and the driver may block the glare by pushing the function button when they feel that their eyes are dazzled. For the driver's convenience, the function button may be provided near the steering wheel.

[0120] Meanwhile, the input unit (60) may further include a microphone for receiving voice commands, and the control unit (100) may control the suspension (200) based on receiving a preset voice signal through the microphone.

[0121] In this case, the preset voice signal may refer to a voice signal capable of determining whether the user intends to select the direct light blocking function.
