The present invention relates to unmanned autonomous vehicles, and more particularly, to unmanned autonomous vehicles for passengers or cargo via a specific location while traveling along a predetermined route from an origin to a destination.
While driving, an autonomous vehicle acquires and processes external information to detect a surrounding environment, determines a driving route, and operates the vehicle independently using self-power. In other words, the autonomous vehicle, using maps, satellite navigation systems (GPS), and various sensors, is capable of detecting the surrounding environment and determining the route to travel along the route by manipulating a steering wheel, accelerator, brake, etc. An implementation of the autonomous vehicle requires a variety of automatic control technologies such as distance maintenance, lane departure warning, lane keeping assistance, rear/side warning, cruise control and automatic emergency braking.
For the autonomous vehicle, the term ‘autonomous vehicle’ is used for both a manned vehicle and an unmanned vehicle. However, a vehicle that performs all the decisions and controls necessary for driving without a driver, is specifically referred to as ‘an unmanned autonomous vehicle’ or ‘a driverless autonomous vehicle.’ A subject of driving of the manned autonomous vehicle may be the vehicle itself or the driver. In contrast, a subject of driving of the unmanned autonomous vehicle is the vehicle itself due to an absence of the driver.
In using such conventional unmanned autonomous vehicles, there is no suitable way for passengers who desire to board the unmanned autonomous vehicle to communicate their intent to the unmanned autonomous vehicle at a bus stop (or bus station).
According to an aspect of the present invention, an object of the present invention is to enable passengers waiting at a bus stop (or bus station) to show or transmit boarding intentions of the passengers to board an unmanned autonomous vehicle.
It is an aspect of the present invention to provide a method of controlling an unmanned autonomous vehicle that may include: acquiring a boarding intention of a passenger who intends to board the unmanned autonomous vehicle; and determining whether to stop the unmanned autonomous vehicle at a bus stop based on the acquired boarding intention of the unmanned autonomous vehicle.
The acquiring of the boarding intention may include: photographing the bus stop using a camera; and determining that the passenger indicates the boarding intention of the unmanned autonomous vehicle when a predetermined indication of the boarding intention is included in a photographed image. The predetermined indication of the boarding intention may include the passenger making a predetermined gesture to indicate the boarding intention; and the unmanned autonomous vehicle may be configured to verify the boarding intention by capturing the gesture of the passenger using the camera.
The predetermined indication of the boarding intention may include operating a button provided at the bus stop to turn on an indicator linked to the button; and the unmanned autonomous vehicle may be configured to photograph the indicator by the camera and verify the boarding intention based on whether the indicator is turned on. The acquiring of the boarding intention may include: receiving a wireless communication signal generated in response to the boarding intention of the passenger; and determining that the passenger indicates the boarding intention of the unmanned autonomous vehicle when a predetermined indication of the boarding intention is included in the wireless communication signal.
The indication of the boarding intention of the passenger may include inputting the boarding intention through a touch display provided at the bus stop; and the unmanned autonomous vehicle may be configured to verify the boarding intention by receiving the input of the touch display via wireless communication. The indication of the boarding intention of the passenger may further include inputting the boarding intention via a mobile device; and the unmanned autonomous vehicle may be configured to verify the boarding intention by receiving the input of the mobile device via wireless communication.
It is another aspect of the present invention to provide an unmanned autonomous vehicle that may include: an acquiring device configured to acquire a boarding intention of a passenger intending to board the unmanned autonomous vehicle; and a controller configured to determine whether to stop the unmanned autonomous vehicle at a bus stop based on the acquired boarding intention of the unmanned autonomous vehicle.
The acquiring device may include a camera configured to capture or photograph an image of the next bus stop; and the controller may be configured to determine that the passenger indicates the boarding intention of the unmanned autonomous vehicle when a predetermined indication of the boarding intention is included in a photographed image. The predetermined indication of the boarding intention may include the passenger making a predetermined gesture to indicate the boarding intention; and the unmanned autonomous vehicle may be configured to verify the boarding intention by photographing the gesture of the passenger using the camera.
The predetermined indication of the boarding intention may also include operating a button provided at the bus stop to turn on an indicator linked to the button; and the unmanned autonomous vehicle may be configured to photograph the indicator by the camera and verify the boarding intention based on whether the indicator is turned on. The acquiring of the boarding intention may include: receiving a wireless communication signal generated in response to the boarding intention of the passenger; and determining that the passenger indicates the boarding intention of the unmanned autonomous vehicle when a predetermined indication of the boarding intention is included in the wireless communication signal.
Additionally, the indication of the boarding intention of the passenger may include inputting the boarding intention through a touch display provided at the bus stop; and the unmanned autonomous vehicle verifies the boarding intention by receiving the input of the touch display via wireless communication. The indication of the boarding intention of the passenger may also include inputting the boarding intention via a mobile device; and the unmanned autonomous vehicle may be configured to verify the boarding intention by receiving the input of the mobile device via wireless communication.
It is yet another aspect of the present invention to provide a method of controlling an unmanned autonomous vehicle that may include: acquiring, by an acquiring device, a boarding intention of a passenger who intends to board the unmanned autonomous vehicle by photographing a bus stop using a camera; determining, by a controller, that the passenger indicates the boarding intention of the unmanned autonomous vehicle when a predetermined indication of the boarding intention is included in a photographed image; and determining, by the controller, whether to stop the unmanned autonomous vehicle at the bus stop based on the acquired boarding intention of the unmanned autonomous vehicle.
It is yet another aspect of the present invention to provide a method of controlling an unmanned autonomous vehicle that may include: acquiring, by an acquiring device, a boarding intention of a passenger who intends to board the unmanned autonomous vehicle by receiving a wireless communication signal generated in response to the boarding intention of the passenger; determining, by a controller, that the passenger indicates the boarding intention of the unmanned autonomous vehicle when a predetermined indication of the boarding intention is included in a photographed image; and determining, by the controller, whether to stop the unmanned autonomous vehicle at the bus stop based on the acquired boarding intention of the unmanned autonomous vehicle.

As shown in
When the passengers already on board the unmanned autonomous vehicle 100 want to get off at a bus stop 150, an intention to get off may be expressed by pressing a button for getting off inside the unmanned autonomous vehicle 100. The unmanned autonomous vehicle 100 may thus be configured to stop at the stop 150 in response to the intention of the passengers to get off to allow the passengers to get off. In contrast, in the conventional unmanned autonomous driving system, there was no way for passengers waiting at the stop to communicate an intention to board the conventional unmanned autonomous vehicle.
Accordingly, in the unmanned autonomous driving system according to an exemplary embodiment of the present invention, waiting passengers 152 and 154 waiting at the stop 150 may indicate (e.g., display or communicate) an intention to board the unmanned autonomous vehicle 100, to the unmanned autonomous vehicle 100. As a result, the convenience of the passengers using the unmanned autonomous vehicle 100 is improved. An apparatus and method for indicating the boarding intention of the unmanned autonomous driving system according to an exemplary embodiment of the present invention will be described in detail with reference to
The controller 202 may be configured to execute the overall operation of the unmanned autonomous vehicle 100. While the vehicle is being driven, the controller 202 may be configured to acquire and process external information to detect a surrounding environment, determine a driving route of the unmanned autonomous vehicle 100, and allow the unmanned autonomous vehicle 100 to operate independently using self-power. For this purpose, the controller 202, using precise maps, satellite navigation systems (GPS), and various sensors, may be configured to detect the surrounding environment and determine the route, and travel along the route by manipulating a steering wheel, accelerator, brake, etc., to implement various automatic control technologies such as distance keeping, lane departure warning, lane keeping assistance, rear/side warning, cruise control and automatic emergency braking.
The camera 204 may be configured to acquire an image (e.g., still image or video) by photographing a predetermined range in front of the unmanned autonomous vehicle 100. The image acquired through the camera 204 may be analyzed by the controller 202. The controller 202 may be configured to determine whether there are any of the waiting passengers 152 and 154 intending to board at the next stop 150 by analysis of the image. In response to determining that there are the waiting passengers 152 and 154 intending to board the unmanned autonomous vehicle 100 at the next stop 150, the controller 202 may be configured to stop the unmanned autonomous vehicle 100 at the next stop 150 to allow the waiting passengers 152 and 154 to board the unmanned autonomous vehicle 100.
In
The communicator 206 of the unmanned autonomous vehicle 100 may be configured to receive the wireless communication signal transmitted from the boarding intention indicating device of the bus stop 150 and transmit the wireless communication signal to the controller 202. The controller 202 may then be configured to determine whether there are any of the waiting passengers 152 and 154 intending to board the unmanned autonomous vehicle 100 at the next bus stop 150 by analyzing the wireless communication signal received via the communicator 206. In response to determining that there are the waiting passengers 152 and 154 intending to board the unmanned autonomous vehicle 100 at the next bus stop 150, the controller 202 may be configured to stop the unmanned autonomous vehicle 100 at the next bus stop 150 to allow the waiting passengers 152 and 154 to board the unmanned autonomous vehicle 100.
Gestures for indicating the boarding intention are not limited to those shown in
When the traffic vulnerable indicates the boarding intention at the bus stop 150, the controller 202 of the unmanned autonomous vehicle 100 may be configured to stop the unmanned autonomous vehicle 100 at the bus stop 150 and create a convenient boarding environment. For example, when the waiting passenger 154 in a wheelchair shows the intention to board, the controller 202 may be configured to prepare traffic vulnerable assistance equipment (e.g., a ramp or a lifting device) of the unmanned autonomous vehicle 100. The waiting passenger 154 in the wheelchair is considered to be able to more easily and conveniently board the unmanned autonomous vehicle 100. Particularly, the traffic vulnerable may include a person with a disability, a person using a wheelchair or crutches, a pregnant woman, an elderly person who has difficulty in mobility, a young child, or the like.
As shown in
The waiting passenger 152 may select an intention to board the unmanned autonomous vehicle 100 and set the boarding intention through the touch display of the smart traffic sign 462. When the indication (setting) of the boarding intention of the waiting passenger 152 is completed, the boarding intention of the waiting passenger 152 may be transmitted to the unmanned autonomous vehicle 100 via wireless communication, and the controller 202 of the unmanned autonomous vehicle 100 may be configured to verify the boarding intention of the waiting passenger 152. The smart traffic sign 462 allows the waiting passenger 152 to search for information related to the unmanned autonomous vehicle 100 that the waiting passenger 152 intends to board, and the boarding intention may be input based on the search result. For this purpose, the touch display of the smart traffic sign 462 may be configured to display information such as a specified number, a driving route, and a current location of the unmanned autonomous vehicle 100. In addition, the smart traffic sign 462 may provide a user interface that allows the waiting passenger 152 to search for various information of the unmanned autonomous vehicle 100 by inputting a specific route or a specific number and to input the boarding intention.
In addition, the smart traffic sign 462 may allow the traffic vulnerable to indicate that they are the traffic vulnerable when setting the boarding intention. When the traffic vulnerable indicates the boarding intention at the bus stop 150, the controller 202 of the unmanned autonomous vehicle 100 may be configured to stop the unmanned autonomous vehicle 100 at the bus stop 150 and create a convenient boarding environment. For example, when the waiting passenger 154 in the wheelchair shows the intention to board, the controller 202 may be configured to prepare the traffic vulnerable assistance equipment (e.g., a ramp or a lifting device) of the unmanned autonomous vehicle 100. The waiting passenger 154 in the wheelchair may be considered to be able to more easily and conveniently board the unmanned autonomous vehicle 100. In particular, the traffic vulnerable may include a person with a disability, a person using a wheelchair or crutches, a pregnant woman, an elderly person who has difficulty in mobility, a young child, or the like.
The smart traffic sign 462 as shown in
As shown in
A holding time of a turn on state of the indicator 566 according to the boarding intention of the waiting passenger 152 is limited to the time when the unmanned autonomous vehicle 100 that is traveling toward the bus stop 150 arrives at the bus stop 150. In other words, when the unmanned autonomous vehicle 100 traveling toward the bus stop 150 arrives at the bus stop 150, the indicator 566 may be turned off. As another case, a lighting state of the indicator 566 may be maintained for a predetermined period of time. For example, while the indicator 566 is turned on by pressing the boarding button 564 to indicate that the waiting passenger 152 intends to board, the indicator 566 may be turned off after a predetermined time elapses, regardless of whether the unmanned autonomous vehicle 100 arrives.
When the traffic vulnerable indicates the boarding intention at the bus stop 150, the controller 202 of the unmanned autonomous vehicle 100 may be configured to stop the unmanned autonomous vehicle 100 at the bus stop 150 and create a convenient boarding environment. For example, when the waiting passenger 154 in the wheelchair shows the intention to board, the controller 202 may be configured to prepare the traffic vulnerable assistance equipment (e.g., a ramp or a lifting device) of the unmanned autonomous vehicle 100.
