[0002] This application claims priority to Korean Patent Application No. 10-2020-0041120, filed on April 3, 2020, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to apparatus and methods for providing warnings about driving a vehicle. Background Technology

[0004] In recent years, intelligent driver assistance systems have been developed to improve driver convenience. These systems perform driving assistance functions that take into account the road ahead and obstacles around the vehicle, assisting the driver in maintaining lane position or speed.

[0005] Furthermore, when driver assistance functions cannot be performed, intelligent driver support systems can warn the driver that the function has been deactivated. However, because warnings based on deactivated driver assistance functions are issued in a centralized manner, drivers may not recognize the warnings and may not be able to determine that availability has been reduced. Alternatively, drivers may feel unsafe due to the lack of warnings. Therefore, there is a need for a technology that can output warnings based on the driver's inclinations even when driver assistance functions are deactivated. Summary of the Invention

[0006] This invention aims to solve the aforementioned problems in the prior art while fully retaining the advantages achieved by the prior art. One aspect of this invention provides a vehicle driving warning device and method for outputting a warning based on the driver's inclination when driving assistance functions are deactivated. The technical problems solved by this invention are not limited to those described above, and any other technical problems not mentioned herein will be clearly understood by those skilled in the art from the following description.

[0007] According to one aspect of the invention, an apparatus for issuing warnings regarding vehicle driving may include: a sensor, an input device, and a controller; the sensor being configured to acquire the driver's state and the vehicle's driving state; the input device being configured to receive risk criterion information from the driver, the risk criterion information including a critical speed defined based on the driver's tendencies and the duration of a driving assistance function; and the controller being configured to set at least one additional warning output condition based on the risk criterion information, determine whether the additional warning output condition is met based on the driver's state and the vehicle's driving state, and output a driving warning based on the determined result.

[0008] The controller can be configured to receive risk standard information input from the driver when it determines to deactivate the driver assistance function, based on the vehicle's state obtained from sensors. The controller can be configured to adjust the additional warning output time based on critical speed and hold time. Additionally, the controller can be configured to set the following conditions as additional warning output conditions: the driver's hands are off, no warning is output based on the hands-off state, the vehicle speed exceeds the critical speed, and the hold time of the driver assistance function exceeds the hold time input by the driver.

[0009] The sensor can be configured to obtain the driver's state by sensing the state of the driver's hands leaving the steering wheel. The sensor can be configured to obtain the vehicle's state by sensing the vehicle's speed. The controller can be configured to output an additional warning via an output device at an output time adjusted based on a critical speed and a holding time, when conditions for outputting an additional warning are met, based on the driver's state and the vehicle's state.

[0010] Furthermore, the controller can be configured to output a warning based on disabling driving assistance functions via an output device when the conditions for outputting additional warnings are not met, based on the driver's and vehicle's states. The output device can be configured to output the warning based on disabling driving assistance functions via an image representing the warning, and to output additional warnings via visual pop-up and audible functions. Driving assistance functions may include lane keeping assist.

[0011] According to another aspect of the present invention, a method for issuing a warning regarding vehicle driving may include: obtaining the driver's state and the vehicle's driving state; receiving risk standard information from the driver, the risk standard information including a critical speed defined based on the driver's tendencies and the duration of a driving assistance function; setting at least one additional warning output condition based on the risk standard information; determining whether the additional warning output condition is met based on the driver's state and the vehicle's driving state; and outputting a driving warning based on the determined result.

[0012] Risk criteria information input from the driver can be received in response to determining whether to deactivate the driver assistance function based on the vehicle's state. The additional warning output time can be adjusted based on critical speed and hold time. Additional warning output conditions can be set as follows: the driver is hands-off, no warning is output based on hands-off status, the vehicle speed exceeds the critical speed, and the hold time of the driver assistance function exceeds the hold time input by the driver.

[0013] The driver's state can be obtained by detecting whether the driver's hands are off the steering wheel. The vehicle's state can be obtained by detecting the vehicle's speed. Based on the driver's and vehicle's states, when the conditions for outputting additional warnings are met, control can be executed to output additional warnings at an output time adjusted based on critical speed and hold time.

[0014] Additionally, based on the driver's and vehicle's states, when the conditions for issuing additional warnings are not met, control can be executed to output a warning based on disabling driver assistance functions. This warning can be output via an image representing the warning, and additional warnings can be output via visual pop-ups and audible signals. Driver assistance functions may include lane-keeping assist. Attached Figure Description

[0027] Figure 1 This is a schematic diagram illustrating the configuration of a device for warning about vehicle driving according to an exemplary embodiment of the present invention. Figure 1 As shown, a device 100 for warning about vehicle driving according to an exemplary embodiment of the present invention may include: a sensor 110, an input device 120, an output device 130, a storage device 140, and a controller 150.

[0028] Sensor 110 may include various types of sensors within the vehicle. According to an exemplary embodiment, sensor 110 may be configured to acquire the driver's state and the vehicle's driving state, and transmit the acquired information to controller 150 via an in-vehicle network. According to an exemplary embodiment, sensor 110 may be configured to acquire the driver's state by sensing whether the driver is holding the steering wheel. Furthermore, sensor 110 may be configured to acquire the vehicle's driving state by sensing the vehicle's speed. Additionally, sensor 110 may be configured to acquire the vehicle's driving state by sensing whether a driving assistance function is activated, based on a control signal output when a driving assistance function is activated.

[0029] Input device 120 can be configured to receive risk standard information from the driver, or based on the driver's control output signals. Accordingly, input device 120 can be implemented using at least one or a combination of a scroll wheel, button, knob, touchscreen, touchpad, joystick, or gesture sensor. Specifically, risk standard information may include: a critical speed corresponding to a hazardous environment defined by the driver, and a driving assistance function maintenance time (e.g., duration) corresponding to a hazardous environment defined by the driver. Additionally, the driving assistance function maintenance time may refer to the time during which the driving assistance function is maintained until it is deactivated.

[0030] Output device 130 can be configured to output a driving warning based on the determination result of controller 150. According to an exemplary embodiment, output device 130 can be configured to output a driving warning visually or audibly. Specifically, output device 130 can be configured to output a warning based on disabling driving assistance functions via an image representing the warning, and can be configured to output additional warnings via visual pop-up and audible functions. Accordingly, output device 130 can be implemented using a display device or an audio output device.

[0031] For the operation of the device 100 for warning about vehicle driving according to an exemplary embodiment of the present invention, the storage device 140 may be configured to store at least one algorithm for performing or executing various commands. The storage device 140 may include at least one of flash memory, hard disk, memory card, read-only memory (ROM), random access memory (RAM), electrically erasable programmable read-only memory (EEPROM), programmable read-only memory (PROM), magnetic storage, magnetic disk, or optical disk.

[0032] The controller 150 can be implemented by various processing devices (such as a microprocessor having semiconductor chips capable of performing operations or executions of various commands), and can be configured to perform overall operation of the device 100 for providing warnings about vehicle driving according to an exemplary embodiment of the present invention based on at least one algorithm stored in the storage device 140. Specifically, according to an exemplary embodiment of the present invention, the controller 150 can be configured to: set at least one additional warning output condition based on risk criterion information, determine whether the additional warning output condition is met based on the driver's state and the vehicle's driving state, and output a driving warning based on the determined result.

[0033] More specifically, after the vehicle's ignition is turned on, the controller 150 can be configured to detect whether a driving assistance function is activated based on the driving state obtained from the sensor 110, and in response to determining to deactivate the driving assistance function, the controller 150 can be configured to receive risk standard information input by the driver. Specifically, the driving assistance function can be provided by an Advanced Driving Assistance System (ADAS) and can include, for example, a function to adjust the distance between vehicles and a lane-keeping function. The function to adjust the distance between vehicles adjusts the distance between vehicles by adjusting the longitudinal speed while maintaining the lane, detecting the vehicle ahead and the lane. The lane-keeping function warns the driver about lane departure when the vehicle deviates from the lane, or returns the vehicle to the lane.

[0034] Furthermore, risk standard information input by the driver can be entered via input device 120 and can be differentiated based on the driver's preferences. According to an exemplary embodiment, the driver's preferences may include a preference for frequent detection of additional warning outputs for hazardous situations and a preference for infrequent detection of additional warning outputs for hazardous situations. Specifically, the risk standard information may include: a critical speed corresponding to a hazardous environment defined by the driver and a driving assistance function maintenance time corresponding to a hazardous environment defined by the driver. Additionally, the driving assistance function maintenance time may refer to the time during which the driving assistance function is maintained until it is deactivated.

[0035] For example, when a driver tends to require frequent detection of warning outputs for hazardous situations, the critical speed corresponding to a hazardous environment defined by the driver can be set to approximately 5 kph, and the driving assistance function hold time can be set to approximately 1 second. In another example, when a driver tends to require less frequent detection of warning outputs for hazardous situations, the critical speed corresponding to a hazardous environment defined by the driver can be set to approximately 20 kph, and the driving assistance function hold time can be set to approximately 4 seconds.

[0036] The controller 150 can be configured to set at least one additional warning output condition based on the driver's tendencies using risk criterion information input by the driver. According to an exemplary embodiment, the controller 150 can be configured to set the additional warning output condition as follows: a hands-off state determined based on the driver's state and the vehicle's state; no warning output based on the hands-off state; the vehicle's speed exceeding a critical speed corresponding to a hazardous environment defined by the driver; and the duration of the driver assistance function exceeding the duration of the driver assistance function input by the driver.

[0037] After determining that the driver assistance function is disabled, the controller 150 can be configured to output an additional warning when the driver's state and the vehicle's driving state meet the additional warning output conditions set based on the driver's preferences. Accordingly, the controller 150 can be configured to adjust the additional warning output time based on the critical speed and holding time input by the driver, and can output the additional warning based on the driver's preferences.

[0038] For example, when a driver who tends to require frequent warning outputs for hazardous situations inputs risk criteria information (e.g., a critical speed of approximately 5 kph and a duration of approximately 1 second), and controller 150 determines based on the driver's state that the driver is in a hands-off state (not holding the steering wheel), controller 150 is configured to determine that no warning related to not holding the steering wheel (e.g., a warning based on the hands-off state) is output, and controller 150 is configured to determine based on the vehicle's driving state that the vehicle speed is 10 kph and the driver assistance function is maintained for 3 seconds, controller 150 can be configured to determine that the driver's state and the vehicle's driving state meet the additional warning output conditions. In response to determining that the additional warning output conditions are met, controller 150 can be configured to output a warning based on disabling the driver assistance function and an additional warning. According to an exemplary embodiment, the additional warning can be output via a visual pop-up function or an auditory function.

[0039] Furthermore, when a driver who tends to require frequent warning outputs for hazardous situations inputs risk standard information (e.g., a critical speed of approximately 5 kph and a holding time of approximately 1 second), if the controller 150 determines, based on the driver's state, that the driver is holding the steering wheel (e.g., not in a hands-off state), if the controller 150 determines that a warning related to not holding the steering wheel has been output (e.g., a warning based on hands-off state), or if the controller 150 determines, based on the vehicle's driving state, that the vehicle speed is approximately 5 kph or less or the driving assistance function has been held for approximately 1 second or less, the controller 150 can be configured to determine that the driver's state and the vehicle's driving state do not meet the conditions for additional warning output. Accordingly, the controller 150 can be configured to output only a warning based on disabling the driving assistance function, without outputting additional warnings. According to an exemplary embodiment, when only a warning about disabling the driving assistance function is output, the controller 150 can be configured to output the driving warning by utilizing an image (e.g., a symbol) representing the warning.

[0040] In another example, when a driver who prefers to receive warnings about dangerous situations infrequently inputs risk criteria information (e.g., a critical speed of approximately 20 kph and a duration of approximately 4 seconds), if controller 150 determines, based on the driver's state, that the driver is not holding the steering wheel (e.g., in a hands-off state), controller 150 is configured to determine that no warning related to not holding the steering wheel (e.g., a warning based on the hands-off state) is output, and controller 150 is configured to determine, based on the vehicle's driving state, that the vehicle speed is 30 kph and the driver assistance function is maintained for 5 seconds, controller 150 may be configured to determine that the driver's state and the vehicle's driving state meet the additional warning output conditions. In response to determining that the additional warning output conditions are met, controller 150 may be configured to output a warning based on disabling the driver assistance function and an additional warning. According to an exemplary embodiment, the additional warning may be output via a visual pop-up function or an audible function.

[0041] Furthermore, when a driver who prefers to receive warnings about infrequently detected dangerous situations inputs risk criteria information (e.g., a critical speed of approximately 20 kph and a duration of approximately 4 seconds), if the controller 150 determines, based on the driver's state, that the driver is holding the steering wheel (e.g., not in a hands-off state), if the controller 150 determines that a warning related to not holding the steering wheel has been output (e.g., a warning based on hands-off state), or if the controller 150 determines, based on the vehicle's driving state, that the vehicle speed is 20 kph or less or the driving assistance function has been maintained for 4 seconds or less, the controller 150 can be configured to determine that the driver's state and the vehicle's driving state do not meet the conditions for additional warning output. Accordingly, the controller 150 can be configured to output only a warning based on disabling the driving assistance function, without outputting additional warnings. According to an exemplary embodiment, when only a warning about disabling the driving assistance function is output, the controller 150 can be configured to output the driving warning by utilizing an image (e.g., a symbol) representing the warning.

[0042] Figure 2 This is a flowchart illustrating a method for providing warnings about vehicle driving according to an exemplary embodiment of the present invention. Figure 2 As shown, according to the present invention, in response to determining that the vehicle's ignition device is turned on (step S110), the controller 150 can be configured to determine whether a driving assistance function is disabled (step S120). In response to determining that the driving assistance function is disabled, the controller 150 can be configured to receive risk standard information input by the driver (step S130). The risk standard information in step S130 may include information input differentially based on the driver's preferences.

[0043] According to an exemplary embodiment, the driver's preferences may include a preference for frequent additional warning outputs to detect hazardous situations and a preference for infrequent additional warning outputs to detect hazardous situations. Risk criterion information may include a critical speed corresponding to a hazardous environment defined by the driver and the driving assistance function maintenance time corresponding to a hazardous environment defined by the driver. The driving assistance function maintenance time may refer to the time during which the driving assistance function is maintained until it is deactivated.

[0044] In step S130, controller 150 may be configured to receive risk standard information set by a driver who tends to require frequent warning outputs for hazardous situations, or may receive risk standard information set by a driver who tends to require infrequent warning outputs for hazardous situations. Controller 150 may be configured to set at least one additional warning output condition based on the risk standard information in step S130, according to the driver's preference (step S140). In step S140, according to an exemplary embodiment, controller 150 may be configured to set the following as additional warning output conditions: a hands-off state determined based on the driver's state and the vehicle's state; no warning output based on the hands-off state; the vehicle's speed exceeding a critical speed corresponding to a hazardous environment defined by the driver; and the driving assistance function's duration exceeding the driving assistance function duration input by the driver.

[0045] The controller 150 can be configured to determine, based on the driver's preferences, whether the driver's state and the vehicle's driving state meet the conditions for additional warning output (step S150). Reference will be made below. Figure 2 The specific operation of step S150 is described below. In response to determining in step S150 that the driver's state and the vehicle's driving state meet the additional warning output conditions set based on the driver's preferences (Yes), controller 150 can be configured to determine that the conditions for outputting an additional warning are met and output a warning and an additional warning based on disabling the driving assistance function (step S160). In step S160, according to an exemplary embodiment, the additional warning can be output via a visual pop-up function and an auditory function.

[0046] Simultaneously, in response to determining in step S150 that the driver's state and the vehicle's driving state do not meet the conditions set according to the driver's preferences (No), controller 150 may be configured to output only a warning about disabling the driving assistance function, without outputting additional warnings (step S170). In step S170, according to an exemplary embodiment, when only a warning about disabling the driving assistance function is output, controller 150 may be configured to output the driving warning by outputting an image (e.g., a symbol) representing the warning.

[0047] Figure 3This is a flowchart illustrating a method for determining whether additional warning output conditions are met according to an exemplary embodiment of the present invention. Figure 3 As shown, based on the driver's state, controller 150 can be configured to determine whether the driver is in a hands-off state (step S210). In response to determining in step S210 that the driver is in a hands-off state, controller 150 can be configured to determine whether no warning related to not holding the steering wheel (e.g., a hands-off state warning) is output (step S220). In response to determining in step S220 that no hands-off state warning is output (yes), controller 150 can be configured to determine whether the vehicle speed exceeds a critical speed input by the driver (step S230).

[0048] In response to determining in step S230 that the vehicle speed exceeds a critical speed input by the driver (Yes) based on the vehicle's driving state, controller 150 may be configured to determine whether the duration of the driving assistance function exceeds the driving assistance function duration input by the driver (step S240). In response to determining in step S240 that the duration of the driving assistance function exceeds the driving assistance function duration input by the driver (Yes), controller 150 may be configured to determine that the driver's state and the vehicle's driving state meet the conditions for additional warning output (step S250). In step S250, controller 150 may be configured to output a warning and an additional warning based on disabling the driving assistance function.

[0049] Furthermore, when the controller 150 determines, based on the driver's state, that the driver is not in a hands-off state (step S210), when the controller 150 determines that a warning related to not holding the steering wheel has been output (e.g., a warning based on hands-off state) (step S220), when the controller 150 determines, based on the vehicle's driving state, that the vehicle's speed is less than or equal to a critical speed input by the driver (step S230), or when the controller 150 determines that the duration of the driver assistance function is less than or equal to the duration of the driver assistance function input by the driver (step S240), the controller 150 may be configured to determine that the driver's state and the vehicle's driving state do not meet the conditions for outputting an additional warning (step S260). In step S260, the controller 150 may be configured to output only a warning regarding the deactivation of the driver assistance function, without outputting an additional warning.
