DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) FIG. 1 illustrates one example embodiment of a motor vehicle 10 of the present invention including a central control hub arrangement 12. Vehicle 10 may be an electric and/or semi-autonomous vehicle. All four wheels of vehicle 10 may be steerable such that vehicle 10 may be safely driven at highway speed of 60 mph or more in either of two opposite directions 14, 16. Vehicle 10 includes two opposite ends 18, 20 each having a storage space (e.g., a truck) and/or a service space (e.g., under a hood) in which an engine, motor and other serviceable components of vehicle 10 may be located. Next to each opposite end 18, 20 is a respective windshield 22, 24. Vehicle 10 includes four occupant seats 26, each of which may face toward, and enable a respective human occupant to face toward, and a central space within the passenger compartment in which central control hub arrangement 12 is located.

(7) Arrangement 12 includes a driver control interface 27 having a steering wheel 28, control pedals 30, such as an accelerator pedal and a brake pedal, and a display screen 32. Driver control interface 27 may be carried in either of two opposite rotational directions 34, 36 on an oval, circular, or otherwise closed-loop track 38. Track 38 may be supported by a floor, roof and/or side walls that define the passenger compartment of vehicle 10, for example. Interface 27 may be manually moved along track 38, or may be moved by an electrically-powered actuator (not shown).

(8) By virtue of being movable along track 38, interface 27 may be selectively positionable in front of any one of seats 26, and in front of the human occupants sitting in seats 26, such that any one of the human occupants may operate interface 27 and serve as the driver of vehicle 10. Arrangement 12 may include a mechanical and/or electrical mechanism (not shown) for stably retaining interface 27 in position in front of the human occupant who is serving as the driver. This mechanism may be released when the driving task is switched to another occupant.

(9) Display screen 32, possibly supplemented by other display screens (not shown) which show views analogous to those of conventional rearview and sideview mirrors, may enable any of the occupants to drive vehicle 10 while the occupant is facing in the direction that is opposite to the direction in which vehicle 10 is traveling. However, it is also possible for vehicle 10 to turn around (i.e., switch which end 18, 20 of vehicle is leading and which is trailing) when the driver is switched if necessary for the driver to face in the direction in which vehicle 10 is traveling, which may make the physical forces felt by the driver while driving seem more compatible and/or consistent with the views that he sees on the display screens.

(10) FIG. 2 illustrates an example embodiment of a motor vehicle 210 including a re-positionable driver control interface arrangement 212 of the present invention. Motor vehicle 210 may be a semi-autonomous vehicle and/or an electric vehicle.

(11) Arrangement 212 includes a driver control interface 227 having a steering wheel, control pedals, such as an accelerator pedal and a brake pedal, and one or more display screens (not shown). Driver control interface 227 may be carried in either of two opposite rotational directions 234, 236 on an oval, circular, or otherwise closed-loop track (not shown). The track may be supported by a floor, roof and/or side walls that define the passenger compartment of vehicle 210, for example. Interface 227 may be manually moved along the track, or may be moved by an electrically-powered actuator (not shown).

(12) By virtue of being movable along the track, interface 227 may be selectively positionable in front of any one of seats 226, and in front of the human occupants sitting in seats 226, such that any one of the human occupants may operate interface 227 and serve as the driver of vehicle 210. Each seat 226 may be independently and selectively pivotable between an outwardly facing position, shown in solid lines in FIG. 2, and an inwardly facing position, shown in dashed lines in FIG. 2. The driver's seat may be placed in the outwardly facing position so that the driver can face interface 227. The positions of the other seats 226 other than the driver's may be arbitrary, and may even be placed in intermediate positions between the outwardly facing and inwardly facing positions.

(13) Arrangement 212 may include a mechanical and/or electrical mechanism (not shown) for stably retaining interface 227 in position in front of the human occupant who is serving as the driver. This mechanism may be released when the driving task is switched to another occupant.

(14) Other features of vehicle 210 may be substantially similar to those of vehicle 10, and thus are not described in detail herein in order to avoid needless repetition.

(15) FIG. 3 illustrates another example embodiment of a motor vehicle 310 including a re-positionable driver control interface arrangement 312 of the present invention. Motor vehicle 310 may be a semi-autonomous vehicle and/or an electric vehicle.

(16) Arrangement 312 includes two driver control interfaces 340, 342 each having a steering wheel, control pedals, such as an accelerator pedal and a brake pedal, and one or more display screens (not shown). Driver control interface 340 may be carried on a track (not shown) or by an articulating arm (not shown) between positions in front of two adjacent seats 344, 346. Similarly, driver control interface 342 may be carried on a track (not shown) or by an articulating arm (not shown) between positions in front of two adjacent seats 348, 350. Each of interfaces 340, 342 may be manually moved along the track or on the articulating arm, or may be moved by an electrically-powered actuator (not shown). There may be a switch (not shown) within the passenger compartment which controls which of interfaces 340, 342 is active and may be used for driving vehicle 310. The interface 340, 342 that is inactive and not in use for driving vehicle 310 may be stored in a roof, floor, door, instrument panel, or seat, for example.

(17) By virtue of being movable along the tracks or by the articulating arms, interfaces 340, 342 may be selectively positionable in front of any one of seats 344, 346, 348, 350, and in front of the human occupants sitting in seats 344, 346, 348, 350, such that any one of the human occupants may operate an interface 340, 342 and serve as the driver of vehicle 310. Each seat 344, 346, 348, 350 may be independently and selectively pivotable between an outwardly facing position, shown in solid lines in FIG. 3, and an inwardly facing position, shown in dashed lines in FIG. 3. The driver's seat may be placed in the outwardly facing position so that the driver can face one of interfaces 340, 342. The positions of the other seats 344, 346, 348, 350 other than the driver's may be arbitrary, and may even be placed in intermediate positions between the outwardly facing and inwardly facing positions.

(18) Arrangement 312 may include a mechanical and/or electrical mechanism (not shown) for stably retaining the active interface 340, 342 in position in front of the human occupant who is serving as the driver. This mechanism may be released when the driving task is switched to another occupant.

(19) Other features of vehicle 310 may be substantially similar to those of vehicle 10, and thus are not described in detail herein in order to avoid needless repetition.

(20) Another embodiment (not shown), is substantially similar to vehicle 310 except that there are four driver control interfaces, each associated with and positionable in front of a respective one of four seats in the vehicle. Thus, there is no need for any of the interfaces to be movable between seats. Each of the interfaces may be stowable when not in use.

(21) FIG. 4 illustrates one embodiment of method 400 of the present invention for enabling a motor vehicle to be driven. In a first step 402, a plurality of seats are provided within a passenger compartment of the motor vehicle. Each seat is configured to receive a respective human occupant of the motor vehicle. For example, four occupant seats 26 are provided in vehicle 10.

(22) In a next step 404 a movable driver control interface is provided within the passenger compartment of the motor vehicle. The movable driver control interface enables a human occupant to drive the motor vehicle. For example, driver control interface 27 may be carried in either of two opposite rotational directions 34, 36 on an oval, circular, or otherwise closed-loop track 38. Driver control interface 27 includes a steering wheel 28, control pedals 30, such as an accelerator pedal and a brake pedal, and a display screen 32, allow which enable a human occupant to drive vehicle 10.

(23) In a final step 406, a human occupant is enabled to move the driver control interface to a position in front of any one of the seats such that any one of the human occupants may use the driver control interface to drive the motor vehicle. For example, by virtue of being manually movable along track 38, interface 27 may be selectively positionable by a human occupant in front of any one of seats 26, and in front of the human occupants sitting in seats 26, such that any one of the human occupants may operate interface 27 and serve as the driver of vehicle 10.
