Description

{SYSTEM AMD METHOD FOR DETERMINING VEHICLE DRIVING MODE}

The present invention relates to a system and method for setting a driving mode of a vehicle, and more specifically, to a system and method for setting a driving mode of a vehicle that provides feedback to the driver regarding the driving mode of the vehicle according to the driving situation of the vehicle rather than simply setting the driving mode of the vehicle according to the driver's input, thereby enabling the driver to quickly and conveniently set a driving mode suitable for his or her driving style.

Recently, vehicles have been provided with functions that allow the setting of various driving-related modes in order to improve the marketability of vehicles and provide vehicle performance that matches the driver's driving style.

These driving modes are designed to reflect the driver's driving tendencies, such as the vehicle's steering, suspension, and powertrain, by setting the characteristics of each mode in advance, and allowing the driver to select these to enjoy driving that suits his or her own preferences.

In addition, to overcome the limitation of having to select a mode that has been pre-determined and saved in advance, vehicles are known to have a custom mode in which the driver can individually set the details of the mode to suit himself or herself, or a smart mode in which the electronic control unit in the vehicle learns the driver's driving tendencies and reflects them.

However, in the case of the custom mode, although the driver's detailed item settings are reflected, there is a problem that the driver must reset them each time he or she wants to change the settings, and it is not possible to set them according to the driving situation. In addition, in the case of the smart mode, the detailed item settings are changed according to the driver's driving tendencies, but in order to change the detailed item settings, learning data that can be acquired when the driver has driven for a certain period of time is required, making it difficult to change the settings quickly, and there is a problem that the electronic control unit may set a mode different from what the driver wants.

The matters described as background technology above are only intended to enhance understanding of the background of the present invention, and should not be taken as an acknowledgment that they correspond to prior art already known to those skilled in the art.

FIG. 3 is a drawing illustrating an example of an operation for judging a driving situation and confirming a feedback condition in a system and method for setting a driving mode of a vehicle according to one embodiment of the present invention.
FIGS. 4 and 5 are diagrams illustrating examples of a feedback interface provided in a system and method for setting a driving mode of a vehicle according to one embodiment of the present invention.

Hereinafter, a vehicle driving mode setting system and method according to various embodiments of the present invention will be described in more detail with reference to the attached drawings.

FIG. 1 is a block diagram of a vehicle driving mode setting system according to one embodiment of the present invention.

Referring to FIG. 1, a vehicle driving mode setting system according to one embodiment of the present invention may be configured to include a driving situation determination unit (11) that determines a driving situation of a vehicle while driving, a feedback condition verification unit (13) that determines whether to provide feedback on a driving-related mode setting of the vehicle based on the driving situation determined by the driving situation determination unit (11), and a feedback interface unit (13) that provides a driver with feedback related to the setting of a driving-related mode when it is determined by the feedback condition verification unit (13) to provide feedback.

The driving situation judgment unit (11), feedback condition confirmation unit (13), and feedback interface unit (13) described above may be provided in the form of logic for performing each function within one controller (10).

The driving situation determination unit (11) can determine the driving situation of the vehicle. Here, the driving situation of the vehicle is information that can be determined using information provided by various in-vehicle sensors (21, 23) that generate information for determining the driving situation of the vehicle or a navigation system (30) equipped in the vehicle. For example, the driving situation of the vehicle can be whether the vehicle is driving on a slope, whether the vehicle is driving at a high speed, whether the vehicle is driving on a curved road, or whether the vehicle is driving on a paved/unpaved road.

In order to provide information for the driving situation determination unit (11) to determine the driving situation, a vehicle driving mode setting system according to one embodiment of the present invention may further include a speed sensor (21) that detects the speed of the vehicle, a tilt sensor (23) that detects the gradient of the road on which the vehicle is driving, and a navigation (23) that derives the driving position of the vehicle.

For example, the driving situation judgment unit (11) can determine whether the vehicle is driving on a slope based on the vehicle inclination information provided by the vehicle inclination sensor (21) and the vehicle position information of the navigation (23). In addition, the driving situation judgment unit (11) can determine whether high-speed driving is occurring based on the speed information of the speed sensor (23) and the vehicle position information of the navigation (23) (for example, the type of road on which the vehicle is driving, such as a highway).

The feedback condition verification unit (13) can determine whether to provide feedback on the vehicle's driving-related mode settings based on the driving situation determined by the driving situation determination unit (11).

For example, the feedback condition verification unit (13) may determine to provide feedback when the driving situation judgment unit (11) determines that a specific driving situation continues for a certain period of time or a certain distance. In another example, the feedback condition verification unit (13) may determine to provide feedback when the driving situation judgment unit (11) determines that a specific driving situation has ended.

As another example, the feedback condition verification unit (13) may determine to provide feedback when the driving situation judgment unit (11) determines that a specific driving situation is in progress and determines that the vehicle is stopped or parked. To this end, the vehicle driving mode setting system according to one embodiment of the present invention may further include a parking judgment unit (17) in the controller (10) that determines whether the vehicle is parked or stopped.

The parking judgment unit (17) can also determine whether the vehicle is parked based on vehicle speed information provided by the speed sensor (21) and/or location information (e.g., parking lot) of the navigation system (30).

In addition, the feedback condition verification unit (13) can determine whether to provide feedback based on the time elapsed since the previous feedback was provided. For example, the feedback condition verification unit (13) can determine to provide feedback if the time elapsed since the previous feedback was provided is greater than a preset reference value.

In particular, the feedback condition verification unit (13) may determine whether to provide feedback on the setting of the driving-related mode based on the result of comparing the driving tendency (e.g., vehicle acceleration tendency and/or vehicle brake use tendency, etc.) of the driver in the driving situation determined by the driving situation judgment unit (11) with the preset driving-related mode of the vehicle. For example, if the preset driving-related mode of the vehicle is a comfort mode that aims for comfortable driving, and the driver performs aggressive driving such as rapid acceleration or rapid braking in a specific driving situation of the vehicle, the feedback condition verification unit (13) may determine that the preset driving-related mode of the vehicle and the driving tendency of the driver do not match as a result of comparing them, and may determine to provide feedback suggesting a new driving-related mode. Here, the target for setting the driving-related mode may be, for example, the driving-related mode, the steering sensitivity of the vehicle, the degree of stiffness of the suspension of the vehicle, the shifting tendency of the powertrain of the vehicle, etc.

The feedback interface unit (15) can provide the driver with feedback related to the setting of the driving-related mode if it is determined by the feedback condition verification unit (13) to provide feedback. For example, the feedback interface unit (15) can cause a pop-up window corresponding to the content for which the feedback condition verification unit (13) wishes to provide feedback to be displayed on the screen of the navigation system (30) or the vehicle cluster (40) of the vehicle. The driver can check the pop-up window displayed on the screen of the navigation system (30) or the vehicle cluster (40) and make an input thereto, and the feedback interface unit (15) receives this input and, if necessary, changes the vehicle driving mode pre-stored in the vehicle driving mode determination unit (19) of the vehicle.

The operation and operational effects of the vehicle driving mode setting system according to one embodiment of the present invention configured as described above can be more clearly understood through the description of the vehicle driving mode setting method according to one embodiment of the present invention described below.

FIG. 2 is a flowchart illustrating a method for setting a vehicle driving mode according to one embodiment of the present invention.

Referring to FIG. 2, a method for setting a vehicle driving mode according to one embodiment of the present invention may begin with a step (S11) of determining a driving situation of a vehicle by a driving situation determination unit (11) and collecting information that can determine a driver's driving tendencies in the corresponding driving situation.

In step (S11), the driving situation judgment unit (11) can check the vehicle driving situation (driving on a slope, driving at high speed, driving on a curved road, driving on an unpaved road, etc.) by using information provided by a speed sensor (21) that detects the speed of the vehicle, a tilt sensor (23) that detects the gradient of the road on which the vehicle is driving, and a navigation system (23) that derives location information such as the type of road on which the vehicle is driving.

Next, the feedback condition verification unit (13) can determine whether to provide feedback on the vehicle's driving-related mode settings based on the driving situation determined in step (S11) (S13).

Before step (S13), the feedback condition verification unit (13) may further include a step (S12) in which the specific driving situation is determined to have ended after a specific driving situation has continued for a certain period of time or a certain distance, or the vehicle is determined to have stopped or parked while the specific driving situation is determined to be in progress by the parking judgment unit (17).

FIG. 3 is a drawing illustrating an example of an operation for determining a driving situation and confirming a feedback condition in a system and method for setting a driving mode of a vehicle according to one embodiment of the present invention. In particular, the example illustrated in FIG. 3 is an example of a driving situation of a vehicle uphill driving situation.

When a vehicle is driving as in 'P1' of Fig. 3, at step (S11), the driving situation determination unit (11) can determine that the vehicle is driving up a slope by using the vehicle inclination information provided by the vehicle inclination sensor (23) and the vehicle driving position information provided by the navigation system (30).

Next, when the vehicle finishes driving on an uphill slope like 'P2' of Fig. 3 and then returns to driving on flat ground, at step (S12), the vehicle driving situation determination unit (11) uses the vehicle inclination information provided by the vehicle inclination sensor (23) and the vehicle driving position information provided by the navigation system (30) to confirm that the vehicle driving situation has changed to driving on flat ground, and can proceed to the subsequent step (S13).

As another example, if 'P2' in Fig. 3 indicates that the vehicle is parked or stopped, in step (S12), the parking judgment unit (17) can use the vehicle speed information provided from the vehicle speed sensor (21) and the vehicle driving location information provided from the navigation system (30) to determine that the vehicle is parked, and proceed to the subsequent step (S13).

As another example, step (S12) may determine whether to proceed to the subsequent step (S13) based on the time elapsed since the previous feedback was provided. For example, in step (S12), the feedback condition verification unit (13) may determine to provide feedback if the time elapsed since the previous feedback was provided is greater than or equal to a preset reference value when the vehicle continues to drive on level ground.

In step (S13), the feedback condition verification unit (13) may determine whether to provide feedback on the setting of the driving-related mode based on the result of comparing the driving tendency (e.g., vehicle acceleration tendency and/or vehicle brake use tendency, etc.) of the driver in the driving situation determined by the driving situation determination unit (11) with the preset driving-related mode of the vehicle. As described above, if the driving tendency expected in the preset driving-related mode of the vehicle and the driving tendency actually identified by the driver do not match each other while the driving situation is determined, the feedback condition verification unit (13) may determine to provide feedback.

In step (S13), if the feedback condition verification unit (13) determines that feedback will be provided, the feedback interface unit (15) can cause a pop-up window corresponding to the content for which feedback is to be provided to be displayed on the screen of the vehicle's navigation system (30) or the vehicle cluster (40) (S14).

FIGS. 4 and 5 are diagrams illustrating examples of a feedback interface provided in a system and method for setting a driving mode of a vehicle according to one embodiment of the present invention.

As illustrated in FIG. 4, in step (S14), the feedback interface unit (15) can provide the driver with a pop-up window-type interface that displays information on a preset vehicle driving-related mode ('Comfort' in the example of FIG. 4) and allows selection of changeable vehicle driving-related modes ('More Comfort' and 'More Sporty' in the example of FIG. 4).

In addition, as illustrated in FIG. 5, in step (S14), the feedback interface unit (15) may display information on a preset driving-related mode of the vehicle ('Comfort' in the example of FIG. 5) and provide the driver with an interface in the form of a pop-up window for recommending and confirming a driving-related mode of the vehicle ('Sporty' in the example of FIG. 5) that matches the driver's driving tendency in the driving situation determined by the driving situation determination unit.

Next, the driver can check the pop-up window displayed on the screen of the navigation system (30) or the vehicle cluster (40) and make an input thereon (S15), and the feedback interface unit (15) receives this input and, if necessary, changes the vehicle driving mode stored in the vehicle driving mode determination unit (19) (S16).

If the condition for checking whether feedback is provided in step (S12) is not satisfied, or if it is determined that feedback is not necessary as a result of checking whether feedback is provided in step (S13), or if there is no driver input for a certain period of time after a pop-up window or the like is provided as a feedback interface in step (S15) or if the driver does not wish to change preset vehicle driving-related settings, the previously preset driving-related mode can be maintained as is (S17).

As described above, the system and method for setting a driving mode of a vehicle according to various embodiments of the present invention can provide feedback to the driver so that the driver can directly select a driving-related mode, such as the steering sensitivity of the vehicle, the degree of firmness of the suspension of the vehicle, and the shifting tendency of the powertrain of the vehicle, depending on various driving situations while the vehicle is being driven.

Accordingly, the system and method for setting a vehicle driving mode according to various embodiments of the present invention can set a mode for vehicle driving-related details suitable for the driver according to various driving situations of the vehicle. In addition, since the driver's opinion can be directly reflected, it can satisfy the driver's driving tendency more accurately and quickly than the technology that automatically sets the driving-related mode by understanding the driving tendency, and can provide the driver with higher satisfaction.

Although the present invention has been described and illustrated with respect to specific embodiments thereof, it will be apparent to those skilled in the art that the present invention may be variously improved and modified without departing from the technical spirit of the present invention as defined by the following claims.
