Description

Technical Field

[0001] The present invention relates to a vehicle and a control method thereof for adjusting a speed change of the vehicle based on an emotional state of a user. Background Art

[0002] Conventionally, the development of driving ability relies on subjective evaluation. Specifically, a driving ability evaluation expert performs driving evaluation under various driving conditions to find problems, and a vehicle designer adjusts the setting values ​​of the engine management system (EMS) software and the transmission management system (EMS) software.

[0003] However, when the purpose of considering driving ability is to improve user satisfaction rather than simply provide it as measurement data, the development of such driving ability through subjective evaluation has limitations in satisfying all drivers.

[0004] Therefore, the user's emotional state is an important factor in developing driving ability, and thus a technology for developing driving ability based on the user's emotional state is needed.

[0005] The information included in this Background section of the invention is only for enhancement of understanding of the general background of the invention and is not to be taken as an admission or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

[0048] Hereinafter, a vehicle and a control method thereof will be described with reference to the accompanying drawings.

[0049] Figure 1 is a control block diagram showing a vehicle 100 according to an exemplary embodiment of the present invention.

[0050] refer to Figure 1 According to an exemplary embodiment, the vehicle 100 includes a sensing unit 110 configured to measure the acceleration of the vehicle 100 and the bio-signal of the user; and a control unit 120 configured to determine the emotional state information indicating the emotional state of the user based on the measured bio-signal, and update the set value of the driving ability factor related to the driving ability according to the change of the vehicle speed; an input unit 130 configured to receive the input of the user; a communication unit 140 configured to perform communication with an external server; a storage unit 150 configured to store relevant information indicating the relationship between the driving ability factor and the emotional state information; and an output unit 160 configured to visually or audibly output a message indicating that the set value of the driving ability factor has been updated.

[0051] The sensing unit 110 includes a biosignal sensor 111 for measuring a biosignal of a user of the vehicle 100 and an acceleration sensor 112 for measuring acceleration of the vehicle 100 .

[0052] The sensing unit 110 may measure a biosignal of a user using the biosignal sensor 111 , and may transmit the measured biosignal to the control unit 120 .

[0053] Therefore, the control unit 120 may acquire emotional state information indicating the emotional state of the user based on the biosignal of the user measured by the biosignal sensor 111 .

[0054] The user's bio-signal may include at least one of the user's facial expression, body state, eye state, and voice state.

[0055] Therefore, the biosignal sensor 111 may be provided in the vehicle 100 as various sensors for measuring the biosignal of the user.

[0056] For example, a galvanic skin response (GSR) meter for measuring the user's skin condition, a heart rate (HR) meter for measuring the user's heart rate, an electroencephalogram (EEG) meter for measuring the user's brain waves, a facial analysis device configured to analyze the user's facial expressions, a microphone device configured to analyze the user's voice state, and an eye tracker for tracking the user's eye position.

[0057] Furthermore, the implementation of the biosensor 111 is not limited to the above-mentioned sensors, and the biosensor 111 may be provided in various sensors as long as it can measure a biological signal of a person.

[0058] The sensing unit 110 may measure the acceleration of the vehicle 100 using an acceleration sensor 112 provided in the vehicle 100 , and may transmit the measured acceleration to the control unit 120 .

[0059] Therefore, the control unit 120 may determine whether the vehicle 100 is accelerating or decelerating based on the acceleration measured by the acceleration sensor 112 , and may update the set value of the driving ability factor based on the emotional state information when the vehicle 100 is accelerating or decelerating.

[0060] The control unit 120 according to the exemplary embodiment acquires emotional state information indicating the emotional state of the user based on the measured biosignal, and updates a set value of a driving ability factor related to the driving ability according to a speed change of the vehicle 100 .

[0061] When the acceleration of the vehicle 100 measured by the sensing unit 110 is equal to or greater than a predetermined threshold acceleration, the control unit 120 may acquire emotional state information indicating the emotional state of the user based on the biosignal measured by the sensing unit 110 .

[0062] According to an embodiment, the threshold acceleration may be set to 0 so that only when the vehicle 100 travels at an acceleration, the control unit 120 acquires the emotional state information indicating the emotional state of the user based on the bio-signal measured by the sensing unit 110. That is, only when the speed of the vehicle 100 occurs, the control unit 120 according to the exemplary embodiment may acquire the emotional state information indicating the emotional state of the user based on the bio-signal measured from the sensing unit 110.

[0063] The emotional state information may include at least one type of a positive degree of speed responsiveness of the vehicle 100, a positive degree of speed linearity of the vehicle 100, a positive degree of speed acceleration capability of the vehicle 100, and a negative degree of speed change of the vehicle 100. The acquisition of the emotional state information will be described in detail below.

[0064] The control unit 120 may update the set value of the driving ability factor based on the emotional state information and the related information indicating the relationship between the emotional state information and the driving ability factor related to the driving ability that varies according to the speed of the vehicle 100 .

[0065] Specifically, the control unit 120 may update the setting value of the driving ability factor so that the degree of positivity to the emotional state information increases. Alternatively, the control unit 120 may update the setting value of the driving ability factor so that the degree of negativity to the emotional state information decreases.

[0066] The drivability factor is related to drivability that changes according to the speed of the vehicle 100 , and may include at least one type of acceleration of the vehicle 100 , a rate of change of acceleration, engine revolutions per minute, and engine torque.

[0067] The driving capability according to the change in speed of the vehicle 100 may indicate the acceleration performance of the vehicle 100 and may include a speed response capability indicating how fast the desired speed is reached according to the user's intention, a speed linearity indicating how the linearity or stability of the speed is changed according to the user's intention, and an acceleration capability indicating whether acceleration or deceleration is achieved according to the user's intention.

[0068] The drivability factor is a factor exerting influence on the drivability according to the speed change of the vehicle 100, and may include at least one type of acceleration, rate of change of acceleration, engine rpm, and engine torque of the vehicle 100 as described above.

[0069] However, the drivability factor is not limited to the above and may be variously implemented as long as it can exert an influence on the drivability according to the speed change of the vehicle 100 .

[0070] The correlation information between the emotional state information and the driving ability factor includes information indicating the driving ability factor corresponding to the type of the emotional state information and information indicating the degree of increase / decrease of the set value according to the type of the driving ability factor.

[0071] Therefore, the control unit 120 can determine at least one driving ability factor corresponding to the type of emotional state information based on the correlation information between the emotional state information and the driving ability factor, and update the set value of the determined driving ability factor according to the degree of increase / decrease corresponding to the at least one driving ability factor. The updating of the set value of the driving ability will be described in detail below.

[0072] In addition, when the setting value of the driving ability factor is updated, the control unit 120 may control the sensing unit 110 to measure the bio-signal of the user. Therefore, the sensing unit 110 may measure the bio-signal of the user after the setting value of the driving ability factor is updated.

[0073] The control unit 120 may acquire emotional state information related to the user based on the bio-signal of the user measured after the setting value of the driving ability factor is updated.

[0074] The control unit 120 may compare the emotional state information acquired after updating the set value of the driving ability factor with the emotional state information acquired before updating the set value of the driving ability factor.

[0075] The control unit 120 may adjust the degree of increase / decrease of the set value according to the type of the driving ability factor based on the result of the comparison. Adjusting the degree of increase / decrease of the set value according to the type of the driving ability factor will be described in detail below.

[0076] The control unit 120 may include at least one memory for storing a program for performing the above-mentioned operations and the operations described below, and at least one processor for executing the stored program. When the memory and the processor are each provided with multiple units thereof, the multiple memories and the multiple processors may be integrated in a single chip, or may be provided at locations physically separated from each other.

[0077] The input unit 130 according to an exemplary embodiment may receive an input from a user.

[0078] Specifically, the input unit 130 may receive an input regarding a threshold acceleration for updating a set value of a driving ability factor from a user. That is, the user may adjust the sensitivity regarding updating a set value of a driving ability factor through the input unit 130 by changing a predetermined threshold acceleration.

[0079] However, according to an embodiment, the threshold acceleration may be set to 0 so that only when the vehicle 100 travels at the acceleration, the control unit 120 may acquire the emotional state information indicating the emotional state of the user based on the bio-signal measured by the sensing unit 110. That is, only when the speed of the vehicle 100 occurs, the control unit 120 according to the exemplary embodiment may acquire the emotional state information indicating the emotional state of the user based on the bio-signal measured from the sensing unit 110.

[0080] In addition, the input unit 130 may receive input from the user regarding the correlation information between the emotional state information and the driving ability factor. Specifically, the input unit 130 may receive input from the user indicating a change in the driving ability factor corresponding to the type of emotional state information, and may receive input from the user indicating a change in the degree of increase / decrease of the set value according to the type of the driving ability factor.

[0081] That is, the user may change the predetermined related information through the input unit 130 so that the setting value of the driving ability factor desired by the user is updated.

[0082] Therefore, the control unit 120 may update the set value of the driving ability factor based on the change of the threshold acceleration and the related information received through the input unit 130 .

[0083] The input unit 130 may be provided in a center panel installed in a center portion of the instrument panel, and may be implemented using a physical button, a knob, a touch pad, a touch screen, a stick type control device, a trackball, etc. However, the location and implementation method of the input unit 130 are not limited to the above examples, and may be included without limitation as long as they can implement reception of a user input.

[0084] The communication unit 140 according to the exemplary embodiment performs communication with an external server. Specifically, the communication unit 140 may receive information related to the threshold acceleration and related information between the emotional state information and the driving ability factor from the external server.

[0085] Therefore, the control unit 120 may update the set value of the driving ability factor based on the threshold acceleration and the related information received through the communication unit 140 .

[0086] Therefore, the communication unit 140 may perform communication with an external server using various methods. The communication unit 140 may transmit information to / receive information from an external server using various methods such as radio frequency (RF) communication, wireless fidelity (Wi-Fi) communication, Bluetooth communication, ZigBee communication, near field communication (NFC), ultra-wideband (UWB) communication, etc. The method of performing communication with an external server is not limited to the above method, and may be variously implemented as long as it allows communication with an external server.

[0087] Although the communication unit 140 is shown as a single component for transmitting and receiving signals, the present invention is not limited thereto. For example, a transmission unit for transmitting signals and a reception unit for receiving signals may be separately provided.

[0088] The storage unit 150 according to the exemplary embodiment may store information related to the threshold acceleration, correlation information between emotional state information and driving ability factors, and correlation information between biosignals and emotional factors, and may also store various information related to the vehicle 100 .

[0089] To this end, the storage unit 150 may include non-volatile memory devices such as cache, read-only memory (ROM), programmable ROM (PROM), erasable programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), and flash memory; volatile storage devices such as random access memory (RAM); or other storage media such as hard disk drives (HDD), CD-ROM, etc., but the implementation of the storage unit 150 is not limited thereto.

[0090] The output unit 160 according to the exemplary embodiment may visually or audibly output a message indicating that the set value of the driving ability factor has been updated according to the control of the control unit 120. Therefore, the user may recognize that the set value of the driving ability factor of the vehicle 100 has been updated.

[0091] Specifically, the output unit 160 may include a display unit 161 that visually outputs a message indicating that the set value of the driving ability factor has been updated.

[0092] The display unit 161 may be disposed inside the vehicle 100 and include a panel implemented using one of a cathode ray tube (CRT) panel, a liquid crystal display (LCD) panel, a light emitting diode (LED) panel, an organic light emitting diode (OLED), a plasma display panel (PDP), and a field emission display (FED) panel.

[0093] Furthermore, the output unit 160 may include a speaker 162 for audibly outputting a message indicating that the set value of the driving ability factor has been updated, and the speaker 162 may be provided inside the vehicle 100 .

[0094] Figure 2 is a diagram illustrating a threshold acceleration for updating a drivability factor according to an exemplary embodiment of the present invention.

[0095] refer to Figure 2 The sensing unit 110 according to the exemplary embodiment may measure the acceleration of the vehicle 100 using the acceleration sensor 112 provided in the vehicle 100 , and may transmit the measured acceleration to the control unit 120 .

[0096] The control unit 120 may determine whether the vehicle 100 is accelerating or decelerating based on the acceleration measured by the acceleration sensor 112 , and may update the set value of the driving ability factor based on the emotional state information when the vehicle 100 is accelerating or decelerating.

[0097] Specifically, when the acceleration of the vehicle 100 measured by the sensing unit 110 is equal to or greater than a predetermined threshold acceleration, the control unit 120 may acquire emotional state information indicating the emotional state of the user based on the biosignal measured by the sensing unit 110 .

[0098] For example, when the vehicle 100 is accelerating, when the vehicle 100 has a velocity equal to or greater than X in the direction of increasing speed. 1 m / s 2 When the acceleration is less than the first threshold acceleration, the control unit 120 may acquire emotional state information indicating the emotional state of the user based on the bio-signal measured by the sensing unit 110.

[0099] In addition, when the vehicle 100 is decelerating, when the vehicle 100 has a velocity equal to or greater than X in the direction of decreasing speed 2 m / s 2 When the acceleration is less than the second threshold acceleration, the control unit 120 may acquire emotional state information indicating the emotional state of the user based on the biosignal measured by the sensing unit 110.

[0100] The threshold accelerations including the first threshold acceleration and the second threshold acceleration may be predetermined accelerations that are preset in a design phase and are used to update set values ​​of driving ability factors that exert an influence on driving ability.

[0101] That is, the threshold acceleration may represent a minimum value of acceleration at which the setting value of the driving ability factor affecting the driving ability needs to be updated and at which the driving ability changes by the setting value of the driving ability factor.

[0102] In addition, the threshold acceleration may be changed based on a user's input received through the input unit 130. That is, the user may adjust the sensitivity regarding updating the set value of the driving ability factor through the input unit 130 by changing a predetermined threshold acceleration.

[0103] According to an embodiment, the threshold acceleration may be set to 0 so that only when the vehicle 100 travels at an acceleration, the control unit 120 may acquire the emotional state information indicating the emotional state of the user based on the bio-signal measured by the sensing unit 110. That is, only when the speed of the vehicle 100 occurs, the control unit 120 according to the exemplary embodiment may acquire the emotional state information indicating the emotional state of the user based on the bio-signal measured from the sensing unit 110.

[0104] Figure 3 is a diagram showing correlation information 300 between a biosignal and an emotional factor according to an exemplary embodiment of the present invention, and Figure 4 is a diagram illustrating emotional state information 400 according to an exemplary embodiment of the present invention.

[0105] refer to Figure 3 , the control unit 120 may acquire emotional state information indicating the emotional state of the user using the biosignal of the user measured by the sensing unit 110 and the correlation information 300 between the biosignal and the emotional factors stored in the storage unit 150 .

[0106] The galvanic skin response (GSR) signal has a correlation value of 0.875 with the disgust emotion factor and a correlation value of 0.775 with the anger emotion factor, respectively showing high correlation with the disgust emotion factor and the anger emotion factor. Therefore, the user's bio-signal collected by the GSR meter is configured as a criterion for determining whether the user's emotion is anger or disgust.

[0107] The correlation value between the GSR signal and the joy emotion factor is 0.353, which is a relatively low value, indicating that the joy emotion factor has a small correlation with the GSR signal.

[0108] In addition, the electroencephalogram (EEG) signal has a correlation value of 0.864 with the anger emotion factor and a correlation value of 0.878 with the fear emotion factor, showing a high correlation with the anger emotion factor and the fear emotion factor. Therefore, the user's biological signal collected by the EEG meter is configured as a criterion for determining whether the user's emotion is anger or fear.

[0109] because Figure 3 The information shown is only experimental results, so it may vary depending on the experimental environment.

[0110] In the present manner, the control unit 120 may use the correlation information 300 between the biological signal of the user and the emotional factors to acquire the emotional state information related to the user.

[0111] The emotional state information may include at least one of the following types: a positive degree of the speed responsiveness of the vehicle 100 , a positive degree of the speed linearity of the vehicle 100 , a positive degree of the speed acceleration capability of the vehicle 100 , and a negative degree of the speed change of the vehicle 100 .

[0112] The degree of positivity for the speed responsiveness of the vehicle 100 indicates the user's satisfaction with the speed responsiveness indicating how fast the desired speed is reached according to the user's intention, and the degree of positivity for the speed linearity of the vehicle 100 indicates the user's satisfaction with the speed linearity indicating how the linearity or stability of the speed is changed according to the user's intention.

[0113] In addition, the positive degree of the speed acceleration capability of the vehicle 100 represents the user's satisfaction with the speed acceleration capability indicating whether to achieve acceleration or deceleration according to the user's intention, and the negative degree of the speed change of the vehicle 100 represents the user's dissatisfaction based on the surprise and panic felt by the user when accelerating or decelerating.

[0114] The control unit 120 may distinguish the emotional factors corresponding to each type of emotional state information, and based on the correlation of each emotional factor with the user's emotional state, may acquire the degree of positivity or negativity with respect to the type of emotional state information.

[0115] Up to now, the storage unit 150 may store information indicating the relationship between the type of emotional state information and the emotional factors, and the relationship between the type of emotional state information and the emotional factors may be set at a design stage.

[0116] For example, in response to determining the user's emotion as satisfaction or joy using the user's biosignals measured by the sensing unit 110 and the correlation information 300 between the biosignals and emotional factors stored in the storage unit 150, the control unit 120 can determine that the user has a high degree of positivity about the speed responsiveness of the vehicle 100.

[0117] On the other hand, in response to determining the user's emotion as being dissatisfied or annoyed, the control unit 120 may determine that the user has a low degree of positivity regarding the speed responsiveness of the vehicle 100 .

[0118] Furthermore, in response to determining the user's emotion as satisfied or interested using the user's biosignal and the correlation information 300 between the biosignal and the emotion factor, the control unit 120 may determine that the user has a high degree of positivity on the speed acceleration capability of the vehicle 100 .

[0119] On the other hand, in response to determining the user's emotion as dissatisfied or angry, the control unit 120 may determine that the user has a low degree of positivity regarding the speed acceleration capability of the vehicle 100 .

[0120] Furthermore, in response to determining the user's emotion as satisfied or neutral using the user's biosignal and the correlation information 300 between the biosignal and the emotion factor, the control unit 120 may determine that the user has a high degree of positivity on the speed linearity of the vehicle 100 .

[0121] On the other hand, in response to determining the user's emotion as dissatisfaction or fear, the control unit 120 may determine that the user has a low degree of positivity about the speed linearity of the vehicle 100 .

[0122] Furthermore, in response to determining the user's emotion as satisfied or neutral using the user's biosignal and the correlation information 300 between the biosignal and the emotion factor, the control unit 120 may determine that the user has a low degree of negativity to the speed change of the vehicle 100 .

[0123] On the other hand, in response to determining the user's emotion as disgust, anger, dissatisfaction, annoyance, or fear, the control unit 120 may determine that the user has a high degree of negativity toward the speed change of the vehicle 100 .

[0124] Although some examples of emotions for determining the degree of positivity or negativity according to the type of emotional state information have been described above, the present invention is not limited thereto and may include various emotions as long as they can be used to determine the degree of positivity or negativity according to the type of emotional state information.

[0125] Furthermore, the control unit 120 may determine the correlation of each emotional factor with the emotional state of the user based on the signal strength of each biosignal, and may acquire each type of emotional state information as a quantitative value based on the correlation of the emotional factor with the emotional state of the user.

[0126] For example, the control unit 120 can obtain the degree of positivity for the speed responsiveness of the vehicle 100 and the degree of positivity for the speed acceleration capability of the vehicle 100 as quantitative values ​​between 0 and 100 based on the ratio of the correlation of the satisfaction factor or the joy factor with the user's emotional state to the correlation of the dissatisfaction factor or the boredom factor with the user's emotional state.

[0127] In the present manner, the control unit 120 can acquire each type of emotional state information as a quantitative value.

[0128] Figure 44 is a diagram showing emotional state information 400 according to an exemplary embodiment of the present invention. The emotional state information 400 represents each type of emotional state information as a quantitative value. Figure 4 , the degree of positivity for speed responsiveness has a quantitative value of 40, and the degree of positivity for speed acceleration capability has a quantitative value of 60. The degree of positivity for speed linearity has a quantitative value of 65, and the degree of negativity for speed variation has a quantitative value of 25.

[0129] As described above, the emotional state information acquired by the control unit 120 may be represented by a quantitative value according to its type. Figure 4 It is merely exemplified for the purpose of describing the present invention, and the quantitative value for each piece of emotional state information may vary according to the emotional state of the user.

[0130] When the positivity of the emotional state information 400 is lower than a predetermined threshold or the negativity of the emotional state information 400 is higher than a predetermined threshold, the control unit 120 according to the exemplary embodiment of the present invention may update the setting value of the driving ability factor.

[0131] That is, when the degree of positivity of the emotional state information 400 is lower than a predetermined threshold, the control unit 120 may update the setting value of the driving ability factor so that the degree of positivity of the emotional state information 400 increases.

[0132] Furthermore, when the degree of negativity of the emotional state information 400 is lower than a predetermined threshold, the control unit 120 may update the setting value of the driving ability factor so that the degree of negativity of the emotional state information 400 decreases.

[0133] The predetermined threshold corresponding to each type of emotional state information 400 may be a predetermined acceleration set in advance in a design phase for updating a set value of a driving ability factor exerting an influence on driving ability.

[0134] That is, the predetermined threshold corresponding to each emotional state information 400 corresponds to the degree of positivity or negativity of the emotional state information 400, wherein the set value of the driving ability factor affecting the driving ability needs to be updated, or wherein the driving ability changes according to the set value of the driving ability factor.

[0135] In addition, the predetermined threshold corresponding to each type of emotional state information 400 may be changed based on the user's input received through the input unit 130. That is, the user may adjust the sensitivity of updating the set value of the driving ability factor by changing the predetermined threshold corresponding to each type of emotional state information 400 through the input unit 130.

[0136] Figure 5is a diagram showing correlation information 500 between emotional state information 400 and driving ability factors according to an exemplary embodiment of the present invention.

[0137] refer to Figure 5 , the correlation information 500 between the emotional state information 400 and the driving ability factor includes information indicating the driving ability factor corresponding to the type of the emotional state information 400, and information indicating the degree of increase / decrease of the set value according to the type of the driving ability factor.

[0138] The drivability factor is related to drivability that changes according to the speed of the vehicle 100 , and may include at least one type of acceleration of the vehicle 100 , a rate of change of acceleration, engine revolutions per minute, and engine torque.

[0139] The driving capability according to the speed change of the vehicle 100 indicates the acceleration performance of the vehicle 100, and may include a speed response capability indicating how fast the desired speed is reached according to the user's intention, a speed linearity indicating how the linearity or stability of the speed is changed according to the user's intention, and an acceleration capability indicating whether acceleration or deceleration is achieved according to the user's intention.

[0140] The drivability factor is a factor exerting influence on the drivability according to the speed change of the vehicle 100, and may include at least one type of acceleration, rate of change of acceleration, engine rpm, and engine torque of the vehicle 100 as described above.

[0141] The acceleration of the vehicle 100 indicates a change in the speed of the vehicle 100 over time when the vehicle 100 accelerates or decelerates, and the rate of change of the acceleration of the vehicle 100 indicates a change in the acceleration of the vehicle 100 over time.

[0142] The engine revolutions per minute of the vehicle 100 indicates the number of revolutions at which a crankshaft of an engine provided in the vehicle 100 rotates for one minute, and the engine torque of the vehicle 100 indicates the force that rotates the crankshaft.

[0143] Specifically, the degree of positivity for speed responsiveness in the type of emotional state information 400 may correspond to the rate of change of acceleration or engine revolutions per minute in the type of driving ability factors, and the degree of positivity for speed acceleration capability in the type of emotional state information 400 may correspond to the rate of change of acceleration or engine torque in the type of driving ability factors.

[0144] Furthermore, the degree of positivity for speed linearity in the type of emotional state information 400 may correspond to acceleration or engine revolutions per minute in the type of driving ability factors, and the degree of negativity for speed variation may correspond to acceleration or engine revolutions per minute in the type of driving ability factors.

[0145] In addition, the correlation information 500 between the emotional state information 400 and the driving ability factor includes information indicating the degree of increase / decrease of the set value according to the type of the driving ability factor. Therefore, the control unit 120 can determine the type of the driving ability factor corresponding to the type of the emotional state information 400, and update the set value of the driving ability factor according to the degree of increase / decrease corresponding to the determined type of the driving ability factor.

[0146] The setting value according to the type of the driving ability factor may be set in advance in a design stage, and may be changed according to a user's input received through the input unit 130 .

[0147] In addition, the set value according to the type of driving ability factor may be updated based on the user's emotional state information 400 before and after the update. The degree of increase / decrease in adjusting the set value according to the type of driving ability factor will be described in detail below.

[0148] Figure 6 is a graph showing a vehicle speed of the vehicle 100 after updating a setting value of a driving ability factor according to an exemplary embodiment of the present invention, and Figure 7 is a graph showing a vehicle speed of the vehicle 100 after updating a setting value of a driving ability factor according to another exemplary embodiment of the present invention.

[0149] refer to Figure 6 and Figure 7 The control unit 120 determines at least one driving ability factor corresponding to the type of the emotional state information 400 based on the correlation information 500 between the emotional state information 400 and the driving ability factor, and can update the set value of the determined driving ability factor according to the degree of increase / decrease corresponding to the at least one driving ability factor.

[0150] Specifically, when the degree of positivity in speed responsiveness is determined to be equal to or less than a predetermined threshold value, the control unit 120 determines the rate of change of acceleration or the engine revolutions per minute as at least one driving ability factor corresponding to the degree of positivity in speed responsiveness, and an update may be performed so that the rate of change of acceleration increases according to the degree corresponding to the increase / decrease in the rate of change of acceleration, or the engine revolutions per minute increases according to the degree corresponding to the increase / decrease in the engine revolutions per minute.

[0151] When the degree of positivity for speed acceleration capability is determined to be equal to or less than a predetermined threshold, the control unit 120 determines the rate of change of acceleration or the engine torque as at least one driving capability factor corresponding to the degree of positivity for speed acceleration capability, and an update may be performed so that the rate of change in acceleration increases according to the degree corresponding to the increase / decrease in the rate of change in acceleration, or the engine torque increases / decreases according to the degree corresponding to the increase / decrease in the engine torque.

[0152] In addition, when the degree of positivity for speed linearity is determined to be equal to or less than a predetermined threshold or the degree of negativity for speed change is equal to or greater than a predetermined threshold, the control unit 120 determines acceleration or engine revolutions per minute as at least one driving ability factor corresponding to the acceleration or engine revolutions per minute, and an update may be performed so that the acceleration is reduced according to the degree corresponding to the increase / decrease in the acceleration, or the engine revolutions per minute are reduced according to the degree corresponding to the increase / decrease in the engine revolutions per minute.

[0153] Figure 6 The speed of the vehicle 100 is shown when the user of the vehicle 100 intends to accelerate in the direction of increasing speed.

[0154] like Figure 6 As shown, the user desired speed 610 may be a speed that increases continuously over time.

[0155] The speed 620 before updating the set value of the drivability factor is lower than the speed 610 expected by the user because the acceleration when the speed increase is initiated is lower than the expected acceleration.

[0156] Therefore, the user of the vehicle 100 may feel dissatisfied or annoyed, and the control unit 120 may determine that the degree of positivity on speed responsiveness in the type of emotional state information 400 is equal to or less than a predetermined threshold value based on the user's biosignal.

[0157] In response to determining that the degree of positivity in speed responsiveness is determined to be equal to or less than a predetermined threshold, the control unit 120 may determine the rate of change of acceleration or the engine revolutions per minute as at least one driving capability factor corresponding to the degree of positivity in speed responsiveness, and perform an update so that the rate of change of acceleration is increased according to the degree corresponding to the increase / decrease in the rate of change of acceleration, or the engine revolutions per minute is increased according to the degree corresponding to the increase / decrease in the engine revolutions per minute.

[0158] As a result, it can be seen that the speed 630 after updating the set value of the drivability factor converges to the expected speed 610 faster than the speed 620 before updating the set value of the drivability factor.

[0159] According to the update of the setting value of the driving ability factor, the speed of the vehicle 100 can reach the expected speed more quickly. That is, the speed response capability of the vehicle 100 is improved by updating the setting value of the driving ability factor.

[0160] Therefore, the user of the vehicle 100 may feel more satisfied or more happy, and less dissatisfied or less annoyed than when the setting value of the drivability factor is not updated. Therefore, the degree of positivity on the user's speed responsiveness can be increased.

[0161] In addition, if Figure 6 As shown, the acceleration at the start of the speed increase is lower than expected.

[0162] Therefore, the user of the vehicle 100 may feel dissatisfied or angry. The control unit 120 may determine that the degree of positivity for speed acceleration capability in the type of emotional state information 400 indicating whether acceleration or deceleration is achieved by the user's intention is equal to or less than a predetermined threshold based on the user's biosignal.

[0163] In response to determining that the degree of positivity for speed acceleration capability is determined to be equal to or less than a predetermined threshold, the control unit 120 may determine the rate of change of acceleration or the engine torque as at least one driving capability factor corresponding to the degree of positivity for speed acceleration capability, and perform an update so that the rate of change of acceleration increases according to the degree of increase / decrease corresponding to the rate of change of acceleration, or the engine torque increases according to the degree of increase / decrease corresponding to the engine torque.

[0164] As a result, it can be seen that the acceleration after the setting value of the drivability factor is updated converges to the expected acceleration faster than the acceleration before the setting value of the drivability factor is updated.

[0165] According to the update of the setting value of the driving ability factor, the acceleration of the vehicle 100 can reach the expected acceleration more quickly. That is, the speed acceleration capability of the vehicle 100 is improved by updating the setting value of the driving ability factor.

[0166] Therefore, the user of the vehicle 100 may feel more satisfied or more interested, and less dissatisfied or less angry, than when the set value of the driving ability factor is not updated. Therefore, the positive degree of the user's speed acceleration ability can be increased, and the negative degree of the user's speed change can be reduced.

[0167] Despite Figure 6 Although not shown in the figure, even when the user of the vehicle 100 desires to accelerate in the direction of decreasing the speed, the control unit 120 may update the set value of the driving ability factor.

[0168] Specifically, in response to the degree of positivity in speed responsiveness being equal to or less than a predetermined threshold, the control unit 120 may determine the rate of change of acceleration or the engine revolutions per minute as at least one driving capability factor corresponding to the degree of positivity in speed responsiveness, and perform an update so that the rate of change of acceleration increases according to the degree corresponding to the increase / decrease in the rate of change of acceleration, or the engine revolutions per minute decreases according to the degree corresponding to the increase / decrease in the engine revolutions per minute.

[0169] In addition, in response to the degree of positivity in the speed acceleration capability being equal to or less than a predetermined threshold, the control unit 120 may determine the rate of change of acceleration or the engine torque as at least one driving capability factor corresponding to the degree of positivity in the speed acceleration capability, and perform an update so that the rate of change of acceleration increases according to the degree of increase / decrease corresponding to the rate of change of acceleration, or the engine torque decreases according to the degree of increase / decrease corresponding to the engine torque.

[0170] Similar to Figure 6 , Figure 7 1 shows the speed of the vehicle 100 when the user of the vehicle 100 intends to accelerate in the direction of increasing speed. Figure 7 As shown, different from Figure 6 The speed 620 before updating the set value of the drivability factor is shown, and the speed 720 before updating the set value of the drivability factor has a value greater than the expected speed 710 .

[0171] In addition, if Figure 7 As shown, the acceleration before updating the set value of the drivability has a value greater than the expected acceleration.

[0172] That is, Figure 7 As shown, the user desired speed 710 may be a speed that increases continuously over time.

[0173] The speed 720 before updating the set value of the drivability factor is higher than the speed 710 expected by the user because the acceleration when the speed increase is initiated is higher than the expected acceleration.

[0174] Therefore, the user of the vehicle 100 may feel dissatisfied or afraid, and the control unit 120 may determine that the degree of positivity on speed linearity in the type of emotional state information 400 is equal to or less than a predetermined threshold value based on the user's biosignal.

[0175] In addition, the user of the vehicle 100 may feel disgust, anger, dissatisfaction, distress, or fear, and the control unit 120 may determine that the degree of negativity to speed change in the type of the user's emotional state information 400 is equal to or greater than a predetermined threshold based on the user's biosignal.

[0176] In response to determining that the degree of positivity for speed linearity is equal to or less than a predetermined threshold or the degree of negativity for speed variation is equal to or greater than a predetermined threshold, the control unit 120 may determine acceleration or engine revolutions per minute as at least one drivability factor corresponding to the acceleration or engine revolutions per minute, and perform an update so that the acceleration is reduced according to the degree corresponding to the increase / decrease in the acceleration, or the engine revolutions per minute are reduced according to the degree corresponding to the increase / decrease in the engine revolutions per minute.

[0177] As a result, it can be seen that speed 730 after updating the set value of the drivability factor is lower than speed 720 before updating the set value of the drivability factor, and converges to expected speed 710 faster than speed 720 .

[0178] Furthermore, according to the update of the set value of the drivability factor, the acceleration of the vehicle 100 is lower than the acceleration before the update of the set value of the drivability factor, and reaches the expected acceleration more quickly.

[0179] That is, by updating the set values ​​of the drivability factors, the speed and acceleration of the vehicle 100 are lower than the speed and acceleration before the set values ​​of the drivability factors are updated, thereby improving the speed linearity of the vehicle 100.

[0180] Therefore, the user of the vehicle 100 may feel more satisfied or neutral, and may feel less disgusted, angry, dissatisfied, distressed, or fearful than before the set value of the driving ability factor was not updated. Therefore, the degree of positivity for the user's speed linearity may be increased, and the degree of negativity for the user's speed variation may be reduced.

[0181] Despite Figure 7 Although not shown in the figure, even when the user of the vehicle 100 desires to accelerate in the direction of decreasing the speed, the control unit 120 may update the set value of the driving ability factor.

[0182] Specifically, even when the user intends to accelerate in the direction of decreasing speed, in response to the degree of positivity for speed linearity being equal to or less than a predetermined threshold or the degree of negativity for speed change being equal to or greater than a predetermined threshold, the control unit 120 may determine acceleration or engine revolutions per minute as at least one driving ability factor corresponding to the acceleration or engine revolutions per minute, and perform an update so that the acceleration decreases according to the degree of increase / decrease corresponding to the acceleration, or the engine revolutions per minute decreases according to the degree of increase / decrease corresponding to the engine revolutions per minute.

[0183] Figure 8 is a graph showing update of correlation information 500 between emotional state information 400 and driving ability factors according to an exemplary embodiment of the present invention.

[0184] refer to Figure 8 As shown, when the setting value of the driving ability factor is updated, the control unit 120 may control the sensing unit 110 to measure the bio-signal of the user. Therefore, the sensing unit 110 may measure the bio-signal of the user after the setting value of the driving ability factor is updated.

[0185] The control unit 120 may acquire the user's emotional state information 400 based on the user's biosignal measured after the setting value of the driving ability factor is updated.

[0186] The control unit 120 may compare the emotional state information 400 acquired after updating the set value of the driving ability factor with the emotional state information 400 acquired before updating the set value of the driving ability factor.

[0187] The control unit 120 may adjust the degree of increase / decrease of the set value according to the type of the driving ability factor based on the comparison result.

[0188] Specifically, when the degree of positivity of the emotional state information 400 acquired after the set value of the driving ability factor is updated has a higher quantitative value than the degree of positivity of the emotional state information 400 acquired before the set value of the driving ability factor is updated, or when the degree of negativity of the emotional state information 400 acquired after the set value of the driving ability factor is updated has a lower quantitative value than the degree of negativity of the emotional state information 400 acquired before the set value of the driving ability factor is updated, the control unit 120 can adjust the degree of increase / decrease corresponding to each type of driving ability factor so that the absolute value of the degree of increase / decrease is reduced.

[0189] That is, when the degree of positivity of the emotional state information 400 increases or the degree of negativity of the emotional state information 400 of the user decreases, the vehicle 100 can allow the set value of the driving ability factor not to change within a wide range by reducing the absolute value of the degree of increase / decrease of the set value of the driving ability factor. Therefore, while maintaining the state in which the degree of positivity of the emotional state information 400 increases or the degree of negativity of the emotional state information 400 decreases, the user is prevented from having stress due to changes in the set value of the driving ability within a wide range.

[0190] In addition, when the degree of positivity of the emotional state information 400 acquired after the set value of the driving ability factor is updated has a quantitative value lower than the degree of positivity of the emotional state information 400 acquired before the set value of the driving ability factor is updated, or when the degree of negativity of the emotional state information 400 acquired after the set value of the driving ability factor is updated has a quantitative value higher than the degree of negativity of the emotional state information 400 acquired before the set value of the driving ability factor is updated, the control unit 120 can adjust the degree of increase / decrease corresponding to each type of driving ability factor so that the absolute value of the degree of increase / decrease increases.

[0191] That is, when the degree of positivity of the emotional state information 400 decreases or the degree of negativity of the user's emotional state information 400 increases, the vehicle 100 can allow the set value of the driving ability factor to vary within a wider range by increasing the absolute value of the degree of increase / decrease, so that the degree of positivity of the user's emotional state information 400 increases or the degree of negativity of the user's emotional state information 400 decreases. Therefore, the user can be satisfied from the change of the set value of the driving ability factor within a wide range while allowing the degree of positivity of the emotional state information 400 to be increased or the degree of negativity of the emotional state information 400 to be reduced.

[0192] Therefore, the control unit 120 can adjust the degree of increase / decrease of the set value according to the type of driving ability factor by comparing the emotional state information 400 obtained after updating the set value of the driving ability factor with the emotional state information 400 obtained before updating the set value of the driving ability factor.

[0193] That is, the control unit 120 can update the correlation information 500 between the emotional state information 400 and the driving ability factor by adjusting the degree of increase / decrease of the set value according to the type of the driving ability factor. The correlation information 500 updated in this way may include information related to the degree of increase / decrease of the set value adjusted according to the type of the driving ability factor, and can be stored in the storage unit 150 according to the control of the control unit 120.

[0194] Hereinafter, a method of controlling the vehicle 100 according to an exemplary embodiment will be described. The vehicle 100 according to the above-described embodiment may be applied to the method of controlling the vehicle 100 described below. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 The described configuration may be applied to a method of controlling the vehicle 100 according to an exemplary embodiment not mentioned.

[0195] Fig. 9 is a flowchart of a method of controlling the vehicle 100, which illustrates updating the set values ​​of the driving ability factors.

[0196] refer to Fig. 9 , the vehicle 100 according to the exemplary embodiment can measure the acceleration and biosignal of the user (910). Specifically, the biosignal sensor 111 and the acceleration sensor 112 included in the sensing unit 110 of the vehicle 100 can measure the biosignal of the user and the acceleration of the vehicle 100, respectively.

[0197] Specifically, when the acceleration of the vehicle 100 is equal to or greater than a predetermined threshold acceleration (Yes in operation 920 ), the vehicle 100 according to the exemplary embodiment may acquire emotional state information 400 indicating the emotional state of the user based on the biosignal ( 930 ).

[0198] Specifically, when the acceleration of the vehicle 100 measured by the sensing unit 110 is equal to or greater than a predetermined threshold acceleration, the control unit 120 may acquire emotional state information 400 indicating the emotional state of the user based on the biosignal measured by the sensing unit 110 .

[0199] The emotional state information may include at least one of the following types: a positive degree of the speed responsiveness of the vehicle 100 , a positive degree of the speed linearity of the vehicle 100 , a positive degree of the speed acceleration capability of the vehicle 100 , and a negative degree of the speed change of the vehicle 100 .

[0200] When the degree of positivity of the emotional state information 400 is less than or equal to the threshold or the degree of negativity of the emotional state information 400 is equal to or greater than the threshold, the vehicle 100 according to the exemplary embodiment may determine the type of the emotional state information 400 ( 940 ).

[0201] Specifically, the control unit 120 can compare each of the positive degree of the speed responsiveness of the vehicle 100, the positive degree of the speed linearity of the vehicle 100, the positive degree of the speed acceleration capability of the vehicle 100, and the negative degree of the speed change of the vehicle 100 with the corresponding threshold, and when the positive degree is equal to or less than the threshold or the negative degree is equal to or greater than the threshold, the type of emotional state information 400 can be determined.

[0202] The control unit 120 may update the set value of the driving ability factor based on the emotional state information 400 and the related information 500 indicating the relationship between the emotional state information 400 and the driving ability factor related to the driving ability that varies according to the speed of the vehicle 100 .

[0203] Specifically, the control unit 120 may update the setting value of the driving ability factor so that the degree of positivity of the emotional state information 400 increases. Alternatively, the control unit 120 may update the setting value of the driving ability factor so that the degree of negativity of the emotional state information 400 decreases.

[0204] The drivability factor is related to drivability that changes according to the speed of the vehicle 100 , and may include at least one type of acceleration of the vehicle 100 , a rate of change of acceleration, engine revolutions per minute, and engine torque.

[0205] The driving capability according to the speed change of the vehicle 100 indicates the acceleration performance of the vehicle 100, and may include a speed response capability indicating how fast the desired speed is reached according to the user's intention, a speed linearity indicating how the linearity or stability of the speed is changed according to the user's intention, and a speed acceleration capability indicating whether acceleration or deceleration is achieved according to the user's intention.

[0206] The drivability factor is a factor exerting influence on the drivability according to the speed change of the vehicle 100, and may include at least one type of acceleration, rate of change of acceleration, engine rpm, and engine torque of the vehicle 100 as described above.

[0207] However, the driving ability factor is not limited to the above-mentioned type and may be variously implemented as long as it can exert an influence on the driving ability according to the speed change of the vehicle 100 .

[0208] The correlation information 500 between the emotional state information 400 and the driving ability factor includes information indicating the driving ability factor corresponding to the type of the emotional state information 400 and information indicating the degree of increase / decrease of the set value according to the type of the driving ability factor.

[0209] The vehicle 100 according to the exemplary embodiment may determine at least one driving ability factor corresponding to the type of the emotional state information 400 ( 950 ).

[0210] Specifically, the control unit 120 may determine at least one driving ability factor corresponding to the type of emotional state information based on the correlation information 500 between the emotional state information 400 and the driving ability factor.

[0211] The vehicle 100 according to the exemplary embodiment may update the determined setting value of the driving ability factor according to the degree corresponding to the increase / decrease of the at least one driving ability factor ( 960 ).

[0212] Specifically, the control unit 120 may update the set value of the driving ability factor determined according to the type of the emotional state information 400 according to the degree corresponding to the increase / decrease of the at least one driving ability factor.

[0213] For example, in response to determining that the degree of positivity in speed responsiveness is determined to be equal to or less than a predetermined threshold, the control unit 120 may determine the rate of change of acceleration or the engine revolutions per minute as at least one driving capability factor corresponding to the degree of positivity in speed responsiveness, and perform an update so that the rate of change of acceleration increases according to the degree corresponding to the increase / decrease in the rate of change of acceleration, or the engine revolutions per minute increases according to the degree corresponding to the increase / decrease in the engine revolutions per minute.

[0214] In addition, in response to determining that the degree of positivity for speed acceleration capability is determined to be equal to or less than a predetermined threshold, the control unit 120 may determine the rate of change of acceleration or the engine torque as at least one driving capability factor corresponding to the degree of positivity for speed acceleration capability, and perform an update so that the rate of change of acceleration increases according to the degree of increase / decrease corresponding to the rate of change of acceleration, or the engine torque increases according to the degree of increase / decrease corresponding to the engine torque.

[0215] In addition, in response to determining that the degree of positivity for speed linearity is equal to or less than a predetermined threshold or the degree of negativity for speed change is equal to or greater than a predetermined threshold, the control unit 120 may determine acceleration or engine revolutions per minute as at least one drivability factor corresponding to the acceleration or engine revolutions per minute, and perform an update so that the acceleration is reduced according to the degree corresponding to the increase / decrease in the acceleration, or the engine revolutions per minute are reduced according to the degree corresponding to the increase / decrease in the engine revolutions per minute.

[0216] Fig.10 is a flowchart of a method of controlling the vehicle 100, which shows the degree of increase / decrease of the set value adjusted according to the type of the driving ability factor.

[0217] refer to Fig.10 , when the setting value of the driving ability factor is updated (Yes in operation 1010 ), the vehicle 100 according to the exemplary embodiment may control the sensing unit 110 to measure a bio-signal of the user ( 1020 ).

[0218] Specifically, when the setting value of the driving ability factor is updated, the control unit 120 may control the sensing unit 110 to measure the bio-signal of the user. Therefore, the sensing unit 110 may measure the bio-signal of the user after the setting value of the driving ability factor is updated.

[0219] The vehicle 100 according to the exemplary embodiment may acquire the user's emotional state information 400 based on the measured biosignal ( 1030 ).

[0220] Specifically, the control unit 120 may acquire the user's emotional state information 400 based on the user's biosignal measured after the setting value of the driving ability factor is updated.

[0221] The vehicle 100 according to the exemplary embodiment may compare the emotional state information 400 before the setting value is updated with the emotional state information 400 after the setting value is updated ( 1040 ).

[0222] Specifically, the control unit 120 may compare the emotional state information 400 acquired after the setting value of the driving ability factor is updated with the emotional state information 400 acquired before the setting value of the driving ability factor is updated.

[0223] The vehicle 100 according to the exemplary embodiment may adjust the degree of increase / decrease of the set value according to the type of the driving ability factor based on the comparison result ( 1050 ).

[0224] Specifically, the control unit 120 may adjust the degree of increase / decrease of the set value according to the type of the driving ability factor based on the comparison result.

[0225] For example, when the degree of positivity of the emotional state information 400 acquired after the set value of the driving ability factor is updated has a higher quantitative value than the degree of positivity of the emotional state information 400 acquired before the set value of the driving ability factor is updated, or when the degree of negativity of the emotional state information 400 acquired after the set value of the driving ability factor is updated has a lower quantitative value than the degree of negativity of the emotional state information 400 acquired before the set value of the driving ability factor is updated, the control unit 120 can adjust the degree of increase / decrease corresponding to each type of driving ability factor so that the absolute value of the degree of increase / decrease is reduced.

[0226] That is, when the degree of positivity of the emotional state information 400 increases or the degree of negativity of the user's emotional state information 400 decreases, the vehicle 100 can allow the set value of the driving ability factor not to change within a wide range by reducing the absolute value of the degree of increase / decrease. Therefore, while maintaining the state in which the degree of positivity of the emotional state information 400 increases or the degree of negativity of the emotional state information 400 decreases, the user is prevented from having stress due to changes in the set value of the driving ability within a wide range.

[0227] In addition, when the degree of positivity of the emotional state information 400 acquired after the set value of the driving ability factor is updated has a quantitative value lower than the degree of positivity of the emotional state information 400 acquired before the set value of the driving ability factor is updated, or when the degree of negativity of the emotional state information 400 acquired after the set value of the driving ability factor is updated has a quantitative value higher than the degree of negativity of the emotional state information 400 acquired before the set value of the driving ability factor is updated, the control unit 120 can adjust the degree of increase / decrease corresponding to each type of driving ability factor so that the absolute value of the degree of increase / decrease increases.

[0228] That is, when the degree of positivity of the emotional state information 400 decreases or the degree of negativity of the user's emotional state information 400 increases, the vehicle 100 can allow the set value of the driving ability factor to vary within a wider range by increasing the absolute value of the degree of increase / decrease, so that the degree of positivity of the user's emotional state information 400 increases or the degree of negativity of the user's emotional state information 400 decreases. Therefore, the user can be satisfied from the change of the set value of the driving ability within a wider range while allowing the degree of positivity of the emotional state information 400 to be increased or the degree of negativity of the emotional state information 400 to be reduced.

[0229] Therefore, the control unit 120 can adjust the degree of increase / decrease of the set value according to the type of driving ability factor by comparing the emotional state information 400 obtained after updating the set value of the driving ability factor with the emotional state information 400 obtained before updating the set value of the driving ability factor.

[0230] That is, the control unit 120 can update the correlation information 500 between the emotional state information 400 and the driving ability factor by adjusting the degree of increase / decrease of the set value according to the type of the driving ability factor. The correlation information 500 updated in this way may include information related to the degree of increase / decrease of the set value adjusted according to the type of the driving ability factor, and can be stored in the storage unit 150 according to the control of the control unit 120.

The instructions may be stored in the form of program codes, and when executed by a processor, a program module may be generated to perform the operations of the disclosed exemplary embodiments.

[0232] The computer-readable recording medium includes all kinds of recording media in which instructions decodable by a computer are stored, for example, read-only memory (ROM), random access memory (RAM), magnetic tapes, magnetic disks, flash memories, optical data storage devices, etc.

[0233] As is apparent from the above, a vehicle and a control method thereof can determine the emotional state of a user and adjust the speed change of the vehicle based on the determined emotional state, and thereby provide the user with satisfactory driving capabilities.
