Abstract

A robotic device for turning a steering wheel of a vehicle includes an electric motor and a telescoping turning shaft connected to the motor. An adapter couples the steering wheel to the turning shaft.

Claims

1. A device for turning a steering wheel of a vehicle comprising:

an electric motor;

an adapter having means for connecting to a steering wheel; and

a telescoping turning shaft having a first section connected to said electric motor and a second section connected to said adapter, wherein said first section is movable relative to said second section such that said telescoping turning shaft can be lengthened and shortened so as to allow for variations in distance between said electric motor and said adapter.

2. A device for turning a steering wheel of a vehicle, device comprising:

an electric motor;

a turning shaft connected to said electric motor, said turning shaft defining a turning shaft axis;

an adapter connected to said turning shaft and having means for connecting to a steering wheel;

a base positionable on a driver'"'"'s seat of the vehicle;

a bracket extending upwardly away from said base; and

a motor mount for holding said electric motor thereon, said motor mount being pivotably engaged with said bracket for establishing the turning shaft axis to be substantially parallel to a steering column axis of a vehicle.

3. The device of claim 2, wherein the bracket is formed with a plurality of holes therein, the holes being formed in the bracket in a generally sequential pattern, and wherein the motor mount is formed with at least one motor mount hole, and the device further includes a locking fastener engageable with one of the holes in the bracket and the motor mount hole to thereby hold the motor mount stationary with respect to the bracket.

4. The device of claim 2, wherein the adapter includes:

a ring-shaped wheel mount;

at least one fastener adapted for holding the wheel mount against a steering wheel; and

an adapter element extending away from the wheel mount for engaging the turning shaft.

5. The device of claim 4, wherein the turning shaft includes a distal universal joint including a distal channel formed therein, and wherein the adapter element is splined complementarily to the distal channel to prevent relative rotational motion between the turning shaft and adapter.

6. The device of claim 5, wherein the motor includes a rotor shaft and the turning shaft includes a proximal universal joint including a proximal channel formed therein, and wherein the rotor shaft is keyed complementarily to the proximal channel to prevent relative rotational motion between the rotor shaft and turning shaft.

7. The device of claim 2, wherein said turning shaft telescopes to allow for variations in distance between said electric motor and said adapter.

8. A vehicle comprising:

a steering wheel;

an electric motor;

an adapter connected to said steering wheel; and

a telescoping turning shaft having a first section connected to said electric motor and a second section connected to said adapter, wherein said first section is movable relative to said second section such that said telescoping turning shaft can be lengthened and shortened so as to allow for variations in distance between said electric motor and said adapter.

9. The vehicle of claim 8, wherein the vehicle defines a steering column axis and the turning shaft defines a turning shaft axis, and the vehicle further comprises:

a base positionable on a driver'"'"'s seat of the vehicle;

a bracket extending upwardly away from the base; and

a motor mount for holding the motor thereon, the motor mount being pivotably engaged with the bracket for establishing the turning shaft axis to be substantially parallel to the steering column axis.

10. The vehicle of claim 9, wherein the bracket is formed with a plurality of holes therein, the holes being formed in the bracket in a generally sequential pattern, and wherein the motor mount is formed with at least one motor mount hole, and the vehicle further includes a locking fastener engageable with one of the holes in the bracket and the motor mount hole to thereby hold the motor mount stationary with respect to the bracket.

11. The vehicle of claim 9, wherein the adapter includes:

a ring-shaped wheel mount;

at least one fastener for holding the wheel mount against the steering wheel;

an adapter element extending away from the wheel mount for engaging the turning shaft.

12. The vehicle of claim 11, wherein the turning shaft includes a distal universal joint including a distal channel formed therein, and wherein the adapter element is splined complementarily to the distal channel to prevent relative rotational motion between the turning shaft and adapter.

13. The vehicle of claim 12, wherein the motor includes a rotor shaft and the turning shaft includes a proximal universal joint including a proximal channel formed therein, and wherein the rotor shaft is keyed complementarily to the proximal channel to prevent relative rotational motion between the rotor shaft and turning shaft.

14. A method for turning a steering wheel of a vehicle, comprising the steps of:

disposing an electric motor in the vehicle;

connecting a first section of a telescoping turning shaft to said electric motor;

connecting a second section of said telescoping turning shaft to an adapter;

whereby said first section is moved relative to said second section such that said telescoping turning shaft can be lengthened and shortened to allow for variations in distance between said electric motor and said adapter;

connecting said adapter to the steering wheel; and

activating said electric motor to turn the steering wheel.

15. The method of claim 14, further comprising the step of selectively establishing a turning shaft axis to be substantially parallel to a steering column axis of the vehicle.

16. The method of claim 15, further comprising the steps of:

splining said adapter to said second section of said telescoping turning shaft; and

keying said first section of said telescoping turning shaft to said electric motor.
