Description

TECHNICAL FIELD

Embodiments described herein generally relate to systems and methods for seat positioning modification in a vehicle and, more specifically, to embodiments that alter positioning of at least one vehicle seat in response to an external triggering event.

BACKGROUND

Seat positions in current vehicles are determined to allow a driver to properly operate the vehicle, as well as maximize use of the interior space of the vehicle. Specifically, the vehicle passengers are currently aligned facing the direction the vehicle typically drives. As a result, the passengers may sacrifice comfort, views, and amenities in an effort to maximize use of the interior space. While these current seat configurations may be conducive to human driven vehicles, autonomous vehicles provide new challenges and opportunities.

SUMMARY

Systems and methods for seat positioning modification in a vehicle are described. One embodiment of a method includes arranging a first movable seat in a default arrangement of a vehicle in preparation for receiving a passenger and determining an occurrence of an external triggering event to the vehicle. Some embodiments include, in response to determining the occurrence of the external triggering event, automatically rearranging the first movable seat to a second arrangement to accommodate for the external triggering event.
In another embodiment, a system includes a sensor for determining a number of passengers that enter a vehicle, a first movable seat that includes a mechanism for moving the first movable seat in the vehicle, and a vehicle computing device that includes a memory component. The memory component may store logic that, when executed by the system causes the system to determine the number of passengers that enter the vehicle, arrange the first movable seat according to a default arrangement and the number of passengers, and receive data related to an external triggering event. In some embodiments, the logic causes the system to determine a second arrangement of the first movable seat, based on the external triggering event, and cause the first movable seat to move according to the second arrangement.
In yet another embodiment, a system includes a first movable seat, a second movable seat, and a vehicle that includes a rail configuration for receiving the first movable seat and the second movable seat. The rail configuration may provide a mechanism for the first movable seat and the second movable seat to move in the vehicle. The system may also include a vehicle computing device that is coupled to the vehicle, where the vehicle computing device includes a memory component that stores logic that, when executed by the vehicle computing device, causes the system to arrange the first movable seat and the second movable seat according to a predetermined default arrangement. In some embodiments, the logic causes the system to receive data related to an external triggering event, determine a second arrangement of the first movable seat and the second movable seat, based on the external triggering event, and cause the first movable seat and the second movable seat to move according to the second arrangement.
These and additional features provided by the embodiments of the present disclosure will be more fully understood in view of the following detailed description, in conjunction with the drawings.

DETAILED DESCRIPTION

Embodiments disclosed herein include systems and methods for seat positioning modification in a vehicle. Some embodiments are directed to moving a seat to a center or other position in a vehicle when the vehicle operates in an autonomous mode. As autonomous vehicles advance, there will be a decreased need for human interaction and especially, physical control of the vehicle. As such, the configuration of the driver seat at the left or right side of the vehicle will not be as necessary. Accordingly, some embodiments described herein may be configured such that when only one occupant is present, the passenger may move their seat to the center (or other area) of the vehicle to optimize performance, create more leg room, lie down, etc. Similarly, embodiments may also provide options for the passenger to position his/her seat to change the passenger's view outside the vehicle.
As such, embodiments described herein permit an occupant in an autonomous vehicle to position their seat in the center of the vehicle or elsewhere when there is no other passenger in the vehicle (or when the vehicle is not full). In some embodiments, the center seat position can be the default position or default arrangement for a vehicle. Similarly, some embodiments may provide options for the movable seat to be reconfigured to the substantially central area of the vehicle in response to certain external triggering events. As one example, if a person is in the autonomous vehicle and there is a semi-truck heading toward the vehicle, the seat can be moved to the center of the vehicle (or to an opposite side of the vehicle), either automatically using vehicle sensors or manually by the person sitting in the seat. Similarly, some embodiments may be configured with options for the vehicle occupant to move their seat to a predetermined position, which may include changing direction the occupant is facing, seat orientation, etc. Some embodiments may alter the seat position to provide more optimal weight distribution of the vehicle during turns, uphill, downhill, etc. The systems and methods for seat positioning modification in a vehicle incorporating the same will be described in more detail, below.
Referring now to the drawings, FIG. 1 depicts a vehicle 100 with a plurality of movable seats 112, according to embodiments described herein. As illustrated, the vehicle 100 includes a plurality of vehicle doors 104 a-104 d. Also included is at least one door sensor, such as door sensors 106 a-106 d. Depicted in the vehicle interior 110 are the movable seats 112 a-112 e, as well as a vehicle computing device 120. As illustrated, the movable seats 112 a-112 e are arranged in a traditional arrangement for a passenger vehicle. Specifically, the movable seats 112 a and 112 b are arranged such that a driver and a first passenger may sit in the “front seat,” with the movable seats 112 c, 112 d, and 112 e being in the “back seat.” While in many current passenger vehicles, the seats are adjustable (and sometimes removable), many current solutions are not movable such that that the seats may be rearranged, as described herein.
Specifically, the vehicle interior 110 may include a rail configuration and/or other systems for moving one or more of the movable seats 112 a-112 e as described herein. Specifically, embodiments described herein are configured such that the movable seats 112 a-112 e may be moved, such as forward, backward, laterally (left and/or right) spun, folded, and stowed in a trunk or other area. As a result, some embodiments may include motors, rails, and/or other mechanisms for automatically moving the movable seats 112 a-112 e as described herein. While some embodiments may automatically move the movable seats 112 a-112 e, some embodiments may be configured for manual motorized movement and/or manual non-motorized movement of the movable seats 112 a-112 e.
The vehicle 100 also includes a vehicle computing device 120 with a memory component 140. The memory component 140 may store detection logic 144 a and arrangement logic 144 b. As described in more detail below, the detection logic 144 a may cause the vehicle 100 to detect the number of passengers that will enter the vehicle 100 and/or have already entered the vehicle 100. As an example, the door sensors 106 a-106 d may be configured to receive data related to a number of passengers the vehicle 100 will receive and/or other data. The sensors 106 a-106 d may additionally provide data and/or a signal to the vehicle computing device 120 related to the number of passengers. In some embodiments, the vehicle 100 may include weight sensors or other sensors in the seats. In some embodiments a key fob or other mobile device may be utilized to automatically identify a number of passengers (such as via a user selection on the mobile device and/or a via a proximity detection of the mobile devices by the vehicle computing device 120). In still some embodiments, the vehicle 100 may provide one or more user interfaces (such as those depicted in FIGS. 3A-3D) for making this determination.
Regardless, the arrangement logic 144 b may cause the vehicle 100 to determine a desired arrangement of the movable seats 112 a-112 e based on the number of passengers, as well as an external triggering event. An external triggering event could include a user preference, a geographic location that the vehicle 100 has reached, a terrain that the vehicle 100 will encounter, a time of day, a sun position, a user selection, an impending vehicle collision, and/or other events.
FIGS. 2A, 2B depict different seating positions for the vehicle 100, according to embodiments described herein. As illustrated in FIG. 2A, the vehicle computing device 120 may determine that only a single passenger may enter the vehicle 100. As the vehicle 100 may be an autonomous vehicle (and/or operate at least partially in an autonomous mode), the vehicle computing device 120 may determine a default arrangement of the movable seat 112. In some embodiments, the default arrangement may be at a central area of the vehicle 100, but other positions may be set and/or otherwise determined. A display 222 and/or other human machine interface may be coupled with the vehicle computing device 120 for facilitating input and/or outputs with a passenger and/or user.
Accordingly, the vehicle 100 may cause the movable seat 112 a to move to the center of the vehicle 100. Depending on the particular embodiment, the movable seat 112 a may be positioned facing in the direction of movement, while other embodiments may utilize a different seat orientation. Additionally, the other movable seats 112 b-112 e may be moved to a position that does not interfere with the passenger. As illustrated, some embodiments may be configured to fold and stow the other movable seats 112 b-112 e (such as in a front trunk and/or back trunk).
As described in more detail below, while the movable seat 112 a may be positioned in the center of the vehicle 100, some embodiments may be configured to move the movable seat 112 a (and/or at least a portion of the other movable seats 112 b-112 e), based on an external triggering event. As an example, the vehicle 100 may determine a route and/or a current location of the vehicle 100 and may determine that a scenic view is on the left side of the vehicle 100. In preparation of reaching that scenic view, the movable seat 112 a may move to a second arrangement to provide a better view to the passenger. The second arrangement may be a preset arrangement, may be determined by the user and/or may be determined from past user actions. Similarly, some embodiments may determine that the sun is positioned relative to the vehicle 100 such that the position of the movable seat 112 a is forcing the passenger to look into the sun. As such, the movable seat 112 a may be moved to reduce this uncomfortable position.
Similarly, embodiments may be configured to utilize the door sensors 106 a-106 d and/or other vehicle sensors (such as via a collision avoidance system) to determine an impending collision with another object (such as another vehicle, a stationary object, etc.). In response to detecting the impending collision, the vehicle computing device 120 may cause the movable seat 112 a (and/or the other movable seats 112 b-112 e) to a more desirable position to prepare for the collision.
As another example, some embodiments may be configured to determine terrain at a geographic location. The terrain may include elevation change, bank, road condition, etc. Based on the determined terrain, the vehicle computing device 120 may cause at least one of the movable seats 112 a-112 e to move. As an example, if the vehicle computing device 120 determines a hard left turn upcoming, the movable seats 112 a-112 e may move to the left side of the vehicle 100 to more easily make the turn.
Accordingly, in FIG. 2B, the vehicle computing device 120 has determined that two passengers will enter the vehicle 100. Accordingly, the vehicle computing device 120 may cause the movable seats 112 a, 112 b (e.g., a first movable seat and a second movable seat) to move to a predetermined default arrangement for that number of passengers. The other movable seats 112 c-112 e may be folded and/or stowed in a position that does not interfere with the passengers. Additionally, the movable seats 112 a, 112 b may be moved to accommodate passenger viewing preferences, collision preparation, and/or to prepare for other external triggering event.
FIGS. 3A-3D depict user interfaces for controlling positions of at least a portion of the seats in the vehicle 100, according to embodiments described herein. As illustrated in FIG. 3A, the vehicle computing device 120 may provide, via a display 222, a user interface 330 that provides options related to the movable seats 112 a-112 e. Specifically, the user interface 330 includes a move seats option 332, an auto move option 334, and a detection option 336. In response to selection of the move seats option 332, the passenger may be provided with the user interface 340 depicted in FIG. 3B. In response to selection of the auto move option 334, the passenger may be provided with the user interface 350 from FIG. 3C. In response to selection of the detection option 336, the passenger may be provided with the user interface 360 from FIG. 3D.
As illustrated in FIG. 3B, the user interface 340 provides options 342 a-342 e for the passenger to determine a desired position of one or more of the movable seats 112 a-112 e. As an example the passenger may manually determine a location for one or more of the movable seats 112 a-112 e via selection of the options 342 a-342 e. Also included is a stow option 344. In response to the passenger directing one or more of the options 342 a-342 e to the stow option 344, the vehicle computing device 120 will cause the vehicle 100 to automatically stow the selected movable seat 112 a-112 e in a predetermined location. The predetermined location may depend on the particular movable seat 112 a-112 e and/or the position of that movable seat 112 a-112 e when being stowed.
As illustrated in FIG. 3C, the user interface 350 includes a collision option 352, a sightseeing option 354, a lighting option 356, and a custom option 358. In response to a passenger selection of the collision option 352, one or more options related to determining an action to be taken when a collision is determined to be occurring. Some embodiments may include an option for the user to determine that at least a portion of the movable seats 112 a-112 e that are in use are moved to a central area of the vehicle 100. Similarly, some embodiments may provide options for the passenger to determine that at least a portion of the movable seats 112 a-112 e are moved to an opposite side of the vehicle 100 prior to a collision. Similarly, some embodiments may provide options for the passenger to determine a level of certainty that the collision will take place for triggering the movement of the movable seats 112 a-112 e.
In response to selection of the sightseeing option 354, the passenger may determine at what geographic locations, terrains, and/or types of sights to implement movement of the movable seats 112 a-112 e. Similarly, some embodiments may provide the passenger with options regarding whether the movement is automatic or manual.
In response to selection of the lighting option 356, the movable seats 112 a-112 e may be moved in response to a position of the sun, moon, headlights from other vehicles, and the like. As an example, the user may determine that the movable seats 112 a-112 e are moved in response to a determination that the sun is directed at a predetermined side of the vehicle 100 (such as to avoid direct sunlight to those passengers). As another example, the user may determine that the movable seats 112 a-112 e are moved in response to headlights being directed at the passengers.
In response to selection of the custom option 358, the passenger may provide custom movement settings, such as to always face forward, always face backwards, always position in the middle of the vehicle 100, etc. Other settings may also be provided by the passenger.
As also illustrated, FIG. 3D the user interface 360 includes a vehicle sensors option 362, a user selection option 364, a mobile device option 366, and a custom option 368. In response to a user selection of the vehicle sensors option 362, the user may determine whether the number of passengers that enter the vehicle 100 is calculated via vehicle sensors. As described above, the vehicle sensors may include the door sensors 106 a-106 d, a seat sensor, an image sensor, a laser sensor, a radar sensor, and the like for determining a number of passengers. If the user deselects the vehicle sensors option 362, other mechanisms may be utilized for determining the number of passengers. If the vehicle sensors option 362 is selected, the user may determine which of the vehicle sensors are utilized for this purpose.
In response to selection of the user selection option 364, a user input may be selected as the primary factor for determining a number of passengers. As an example, the user may select the number of passenger upon entering the vehicle 100. As another example, each of the passengers may provide a selection to indicate that they will enter the vehicle 100.
In response to selection of the mobile device option 366, a mobile phone, key fob, and/or other mobile device may be utilized to determine the number of passengers that are entering the vehicle 100. In some embodiments, the user may provide input regarding whether he/she is entering the vehicle 100 (e.g., the passenger pushes a button on the key fob), while other embodiments provide an option for the passenger to specify the total number of passengers. Similarly, some embodiments are configured to recognize the mobile device that the passenger carries (and/or mobile devices for a plurality of passengers) and determine the number of passengers accordingly.
In response to selection of the custom option 368, the passenger may specify a custom mechanism for determining the number of passengers entering the vehicle 100. As an example, if the vehicle 100 is a form of public transit (such as a taxi or internet based public transit), the number of passengers may be specified by an external server or via other mechanism, which may be specified in response to selection of the custom option 368.
FIG. 4 depicts a flowchart for providing seat positioning modifications, according to embodiments described herein. As illustrated in block 480, a first number of passengers that are entering the vehicle 100 may be determined. As discussed above, the number of passengers may be determined according to any of a plurality of different mechanisms and may change at one or more stops of the vehicle 100. In block 482, a first arrangement of the movable seats 112 a-112 e may be determined. Based on the number of passengers, preference data for each of the passengers, and/or other information, a default arrangement may be established and the movable seats 112 a-112 e may be arranged accordingly. In block 484, an external triggering event may be determined. The external triggering event may include a user preference, an impending collision, and/or other external triggering event that would cause a desire to move at least one of the movable seats 112 a-112 e. In block 486, the movable seats 112 a-112 e may be rearranged to a second arrangement, according to a predetermined response to the external triggering event.
