Referring to FIG. 1, the autonomous driving system according to an embodiment of the present invention includes a passenger state recognition unit 100 for acquiring a passenger's state information, a controller 300 for recommending a vehicle function, and determining a driving mode and a driving path. It is configured to include).

In detail, the controller 300 may include a function recommendation unit 310 for selecting a recommendation function among functions that can be provided by receiving the driver's status information, and a driving mode determination unit 320 for determining a driving mode in consideration of the passenger's status information. ) And a driving route determination unit 330 for determining a driving route of the vehicle in consideration of the driving mode and external factor detection information.

The occupant state recognition unit 100 includes a driver state recognition unit 110 and a passenger state recognition unit 120, and includes at least one of an image acquisition unit, an audio acquisition unit, and a device linkage unit. Obtain status information.

The occupant state recognition unit 100 analyzes the image information acquired through the image acquisition unit, and recognizes the passenger's body type information, sleepiness or the like.

The function recommendation unit 310 selects a recommendation function that lowers the temperature setting of the air conditioner when analyzing the image information, for example, when the passenger wipes sweat, and recommends a recommendation function or a rest function to allow ventilation when the passenger is a driver and suspects drowsiness. Select the message presentation function.

If the passenger suspected of drowsiness is not the driver and you are trying to wake up (such as massaging your neck, turning your neck, or swollen eyes), provide a ventilation recommendation feature. If you want to sleep intentionally without action, it offers recommendations such as seat reclining and in-car audio volume reduction.

In addition, the function recommendation unit 310 provides a lock setting as a recommendation function for the window and the car door of the seat when the passenger is a young child.

The function recommender 310 analyzes voice information acquired through the voice acquirer to determine gender and age of the occupant or analyze speech information.

The function recommender 310 selects the warmer function of the seat as a recommendation function and sets the in-vehicle air conditioner according to the analysis result of the speech information such as "hot or cold" when the passenger is an elderly person. Select changes as recommended features.

The device linkage unit may interlock with a wearable device worn by the occupant or a smartphone possessed by the occupant to acquire unique information (ID information), pulse rate, sleep information, schedule information, and the like of the occupant.

The function recommender 310 selects a function such as a ventilation setting, an audio setting, etc. to prevent drowsy driving and recommends a function as a recommended function when it is confirmed that sufficient sleep is not made the previous day through the wearable device of the driver.

The driving mode determination unit 320 considers the passenger's schedule information (eg, meeting schedule and place) and the current location information, and sets the driving mode to the first driving mode (comfortable driving mode, acceleration and lane change to the minimum). ) Or the second travel mode (shortest time travel mode, the mode that allows the shortest time to travel to the destination even if the acceleration and lane change are frequent).

The driving mode determination unit 320 sets the first driving mode for driving stability and stability of the passenger when the passenger is an elderly person or a young child, and needs to move quickly in consideration of schedule information when the passenger is in his twenties. The second driving mode.

The control unit 300 controls so that different recommendation functions are provided without mutual interference with respect to the recommendation functions selected by the function recommendation unit 310.

For example, if the driver is sweating despite wearing a short-sleeved shirt and the air conditioner needs to be turned on, and the passenger recognizes that the passenger is a young child wearing a mask, the air conditioner may cool the driver's seat only. Its direction and intensity are automatically controlled, and the heating function is activated on the passenger's seat.

The function recommendation unit 310 according to an exemplary embodiment of the present invention displays a recommendation function in a widget form in a cluster to provide a driver with a function control right.

The driver may select on / off for the recommended function by using a function control right through gesture recognition, voice recognition, or the like.

According to the exemplary embodiment of the present invention, the driving mode information determined through the driving mode determination unit 320 is interchanged with surrounding vehicles through the communication unit 400.

The driving path determining unit 330 determines the driving path according to the occurrence of the event in consideration of the driving mode information of the own vehicle, the driving mode information of the surrounding vehicle, and the external factor detection information, and the external factor detecting unit 200 determines the ambient noise information. It provides and obtains wind speed information, road surface information and traffic information.

2A to 2D, a driving embodiment using an autonomous driving system according to an embodiment of the present invention will be described.

2A illustrates a current situation for describing an example driving in accordance with an embodiment of the present invention.

It is assumed that the first, second, and third lanes are driving lanes, the first lane is a bus lane, the second lane is crowded with the vehicle ahead, and the third lane has a smooth traffic flow.

The first vehicle A is driving in the first driving mode (comfortable driving mode, driving mode for minimizing acceleration and lane change) according to the above-mentioned occupant state recognition result and driving mode determination result, followed by a second It is assumed that the vehicle B is driving in the second driving mode (the shortest time driving mode, the mode for driving in the shortest time even if the acceleration and the lane change are frequent) according to the occupant status information and the driving mode determination.

Referring to FIG. 2B, since the lane change should be minimized according to the first driving mode, the first vehicle A is decelerated while maintaining a safety distance with the preceding vehicle C to maintain the second lane as the driving lane.

On the other hand, since the second vehicle B must arrive at the destination within a shorter time even if the lane change occurs, the second vehicle B changes the driving lane to the third lane to drive.

Referring to FIG. 2C, it is further assumed that the preceding vehicle C is suddenly stopped.

Although the first vehicle A is traveling according to the first driving mode, the first vehicle A may also need to be suddenly stopped according to the distance information with the preceding vehicle C which has suddenly stopped. If it is determined that changing the driving lane causes less anxiety for the occupant, the driving lane is changed to the third lane.

However, when the distance from the preceding vehicle C quickly stopped and the first vehicle A does not need to stop suddenly, unlike FIG. 2C, the vehicle slowly decelerates gradually without changing the traveling lane. To keep driving lane.

When the first vehicle A changes the driving lane to the third lane, the second vehicle B changes the driving lane in the third lane even if it originally complies with its own driving mode (second driving mode). Recognizing the change of the traveling lane of the first vehicle A, the speed is reduced and the traveling lane is changed to the third lane so that there is no possibility of collision with the first vehicle.

2D illustrates a case where the first vehicle A is driving in the second driving mode and the second vehicle B is driving in the first driving mode, unlike the above description.

At this time, it is assumed that the first, second, and third lanes are driving lanes, the first lane is a bus-only lane, the second lane is crowded with traffic ahead, and the third lane has a smooth traffic flow ahead. Is the same.

The first vehicle A changes the driving lane in three lanes according to the second driving mode, and the second vehicle B changes the lane of the first vehicle in consideration of driving mode information received from the first vehicle A. FIG. Recognize.

When the third vehicle does not cut in front of the second vehicle, the braking target distance of the second vehicle B is increased based on the preceding vehicle C. When the first vehicle A is present, By decelerating more slowly, it is possible to travel more in line with the purpose of the first travel mode.

The driving route determination unit 330 according to an embodiment of the present invention determines the driving route in consideration of noise information, wind speed information, and road surface information received from the external factor detecting unit 200.

For example, it is assumed that the driving vehicle is driving in the first driving mode, and that a case where a large dump truck is running around is recognized according to the noise information and the wind speed information according to the driving environment.

The first driving mode is a mode for minimizing acceleration or lane change and providing driving stability to the passenger, but the driving vehicle changes the driving lane as far as possible from the large dump truck even if the current driving lane is changed.

In addition, when the shaking of the traveling vehicle is anticipated according to the wind speed information, for example, the driving speed is further decelerated, and the control is performed to be less than or equal to the shaking of the predetermined reference, so that the driving meets the purpose of the first driving mode.

So far I looked at the center of the embodiments of the present invention. Those skilled in the art will appreciate that the present invention can be implemented in a modified form without departing from the essential features of the present invention. Therefore, the disclosed embodiments should be considered in descriptive sense only and not for purposes of limitation.
