A method for the controller 300 to generate a recommended emotional path based on the emotional information for each unit section will be described below with reference to FIGS. 4 to 7 .

The display 400 displays the emotional path generated by the controller 300 on the screen. The display 400 may correspond to the display unit of the AVN device 130 . Referring to FIG. 8 , the display 400 displays the emotional path from the origin to the destination on the map, and displays information on the emotional path.

The database 500 stores driver emotion information collected by the emotion information acquisition sensor 220 . In addition, the database 500 stores driver emotion information for each unit section, and when the driver emotion information for the unit section is changed, updates the driver emotion information for the unit section.

In addition, the database 500 may store the recommended emotional route generated by the controller 300 and provide the stored recommended emotional route data when the driver drives the same route later. Therefore, the recommended emotional path can be provided directly without going through a separate emotional path generation process, so that the time it takes to provide the path can be shortened.

4 is a diagram illustrating a detailed configuration of a control unit according to an embodiment.

Referring to FIG. 4 , the control unit 300 includes an emotion information obtaining unit 310 , a unit section calculating unit 320 , and an emotion path calculating unit 330 .

The emotional information acquisition unit 310 analyzes driver emotional information using the signal collected by the emotional information acquisition sensor 220 , or acquires driver emotional information from the input unit 128 , and through the communication unit 200 for each unit section Acquire emotional information. Since the driver's emotional information and the emotional information for each unit section have been described above, a redundant description will be omitted.

The unit section calculating unit 320 extracts a unit section belonging to the same sentiment group based on the emotion information for each unit section. The same sentiment group refers to a group having the same or similar sentiment information. The driver's emotional information or the emotional information of other drivers for a unit section in the entire route generated between the departure point and the destination may be different for each unit section. That is, the unit section calculating unit 320 determines whether the emotion information is the same or similar to generate an emotion group, and if the emotion information for the unit section is the same or similar, it is determined that the emotion information belongs to the same group.

The emotional group may be divided into a pleasure emotional group, a comfortable emotional group, and an angry emotional group, but is not limited thereto.

The emotional path calculating unit 330 may generate an emotional path by connecting unit sections belonging to the same emotional group, and may provide an optimal path among the generated emotional paths as a recommended emotional path.

Also, the unit section calculator 320 may assign different weights to unit sections belonging to different emotional groups. For example, the unit section calculating unit 320 may give a weight of 1 to a unit section belonging to the pleasure sensibility group, 0.5 to a unit section belonging to the comfort sensibility group, and 0 to a unit section belonging to the angry sensibility group.

The emotional path calculating unit 330 may generate, as a recommended emotional path, a path having the highest sum of weights given to each unit section among the emotional paths from the origin to the destination. The reason for creating an emotion path by assigning weights to unit sections belonging to different sentiment groups is that it may not be possible to create an emotion path by connecting unit sections belonging to the same emotion group.

In addition, even if it is possible to generate an emotional route by connecting unit sections belonging to the same emotional group from the departure point to the destination, the arrival time may be outside the allowable range or different from the road type input by the driver. That is, by using the weights assigned to each unit section, it is possible to generate an emotional path that matches the basic information input by the driver.

The unit section calculating unit 320 may extract the unit section belonging to the same emotional group by reflecting emotional information for each unit section that changes according to the driving time and surrounding environment in real time. Even on the same route, the unit section belonging to the same emotional group also varies because the driver's emotions may vary depending on the time of driving the route or changes in the surrounding environment.

For example, since the environment of the commute time and the departure time are different for a certain unit section, and road traffic information is available, the driver's emotional information for the corresponding unit section of the commute time and the departure time may also be different from each other. The time zone may be divided into dawn time, morning time, day time, evening time, and night time.

The emotional route calculating unit 330 may generate a recommended emotional route by connecting unit sections belonging to the same emotional group extracted according to the driving time and surrounding environment.

As described above, the present invention can provide a more optimized emotional path by reflecting emotional information that changes according to the driving time and surrounding environment in real time.

5 is a flowchart of a vehicle control method according to an exemplary embodiment.

Referring to FIG. 5 , the input unit 128 according to an exemplary embodiment receives basic driver information ( 510 ). The driver's basic information may include departure point information, destination information, an allowable range of arrival time, road type, or driver emotion information.

The control unit 300 obtains the driver's emotional information from the emotional information acquisition sensor 220 or the input unit 128 ( 520 ). Also, the controller 300 acquires real-time road traffic information and emotional information for each unit section from the external server 210 ( 530 ). The emotional information for each unit section means emotional information of other drivers for the corresponding unit section for each unit section.

The emotional information may be information corresponding to pleasure, comfort, anger, refreshment, not pleasant, discomfort, anxiety, nervousness, tension, tiredness, pain, discomfort, fear, sleepiness, or sadness.

The controller 300 extracts a unit section belonging to the same emotional group based on the emotion information for each unit section, and connects the unit sections belonging to the same emotional group to generate a recommended emotion path (540). Since the same sentiment group has been described above, a redundant description thereof will be omitted.

When generating the recommended sentiment path, the controller 300 may assign different weights to unit sections belonging to different sentiment groups, and generate a path having the highest sum of weights as the recommended sentiment path.

The display 400 displays the recommended emotional path generated by the controller 300 on the screen ( 550 ).

In this way, the vehicle control method according to an embodiment can provide an emotional route that fits the driver's tendency by generating and displaying a recommended emotional route by reflecting the driver's basic information, the driver's emotional information, the emotional information for each unit section, and the road traffic information. There is an effect of providing an emotional path through which more positive emotions can be expressed based on the driver's current emotional information. Accordingly, it is possible to prevent accidents caused by negative emotions and to reduce the driver's driving stress.

6 is a diagram for explaining how a vehicle calculates a unit section belonging to the same emotion group and generates an emotion path, according to an embodiment.

Referring to FIG. 6 , the controller 300 extracts a unit section belonging to the same emotional group based on the emotional information for each unit section for the entire path that can be created from the origin to the destination, and connects the unit sections belonging to the same emotional group. Create emotional pathways.

In FIG. 6, the solid line is a pleasure path generated by connecting unit sections belonging to the pleasure emotional group, the dashed-dotted line is a comfort path generated by connecting the unit sections belonging to the comfort emotional group, and the broken line is the unit section belonging to the South Korean emotional group. This is the South Korean route created by connecting.

The controller 300 may provide a recommended emotional path in consideration of the basic information input by the driver and the current emotional information of the driver. For example, in FIG. 6 , a pleasure path or a comfort path may be provided as a recommended emotional path.

7 is a view for explaining that a vehicle generates an emotional path by reflecting emotional information that changes according to a driving time, according to an exemplary embodiment.

Referring to FIG. 7 , it can be seen that the emotional path generated according to time zone A, time zone B, and time zone C is different. Since the emotional path of time A is the same as that of FIG. 6 , a description thereof will be omitted.

Looking at the emotional path in time B, it appears that the length of the pleasure path and the comfort path from the origin to the destination is longer than the path in time A. In this case, the controller 300 may determine the comfort route as the optimal route rather than the pleasure route in consideration of the allowable range of arrival time included in the driver's basic information, and provide it as the recommended emotional route.

Looking at time zone C, it can be seen that this corresponds to a case in which an emotional route cannot be created by connecting unit sections belonging to the same emotional group among routes from the origin to the destination. In this case, the controller 300 may assign a weight of 1 to a unit section belonging to the pleasure sentiment group, 0.5 to a unit section belonging to the comfort emotion group, and 0 to a unit section belonging to the angry emotion group.

The controller 300 may provide a route having the highest sum of weights given to each unit section as a recommended emotional route. Even in this case, the recommended emotional route is provided by reflecting the driver's basic information and driver's emotional information.

Referring to time C, the lowermost path including the unit section belonging to the pleasure sensibility group and the unit section belonging to the comfort sensibility group will be provided as the recommended emotional path.

8 is a diagram illustrating an example in which a vehicle displays an emotional path through a display according to an exemplary embodiment.
