Abstract

A steering system for an automotive vehicle is disclosed. The steering system includes a steering column assembly, a steering wheel assembly secured to the steering column assembly, the steering wheel assembly comprising a steering wheel frame, a steering wheel rim, and a hub, and an emulator enclosed within a housing, the emulator secured to the steering column assembly. The steering wheel frame and the hub are stationary and the steering wheel rim rotates relative to the steering wheel frame and the hub.

First claim

What is claimed is:

1. A steering system for an automotive vehicle, comprising:
a steering column assembly;
a steering wheel assembly secured to the steering column assembly, the steering wheel assembly comprising a steering wheel frame, a steering wheel rim, and a hub; and
an emulator coupled to the steering column assembly and providing steering torque feedback via the steering wheel assembly, the emulator comprising a motor enclosed within a housing, the motor secured to the steering column assembly;
wherein the steering wheel frame and the hub are stationary and the steering wheel rim rotates relative to the steering wheel frame and the hub.

2. The steering system of claim 1 , wherein the emulator further comprises a gear set enclosed within the housing, the gear set comprising a shaft having a first gear at a first end of the shaft and a second gear at a second end of the shaft, the first gear configured to engage with the steering wheel rim and the second gear configured to engage with the motor of the emulator such that the gear set transfers torque from the emulator to the steering wheel rim.

3. The steering system of claim 1 , wherein the steering wheel assembly further comprises a plurality of bearings positioned between the steering wheel rim and the steering wheel frame such that the steering wheel rim rotates relative to the steering wheel frame on the plurality of bearings.

4. The steering system of claim 1 , wherein the steering wheel frame is circular.

5. The steering system of claim 1 , wherein the steering wheel frame is oval.

6. The steering system of claim 1 , wherein the emulator is positioned adjacent to the steering wheel assembly.

7. The steering system of claim 1 , wherein the hub is eccentrically positioned relative to the steering wheel frame.

8. An automotive vehicle, comprising:
a plurality of vehicle wheels;
a steering system comprising
a steering column assembly;
a steering wheel assembly secured to the steering column assembly, the steering wheel assembly comprising a steering wheel frame, a steering wheel rim, and a hub; and
an emulator providing steering torque feedback via the steering wheel assembly, the emulator comprising a motor enclosed within a housing, the motor coupled to the steering column assembly;

wherein the steering wheel frame and the hub are stationary and the steering wheel rim rotates relative to the steering wheel frame and the hub;
wherein the steering wheel assembly is positionable between a stowed position and an unstowed position; and
wherein the steering system is connected to the vehicle wheels for steering the vehicle wheels.

9. The automotive vehicle of claim 8 , wherein the emulator further comprises a gear set enclosed within the housing, the gear set comprising a shaft having a first gear at a first end of the shaft and a second gear at a second end of the shaft, the first gear configured to engage with the steering wheel rim and the second gear configured to engage with the motor of the emulator such that the gear set transfers torque from the emulator to the steering wheel rim.

10. The automotive vehicle of claim 8 , wherein the steering wheel assembly further comprises a plurality of bearings positioned between the steering wheel rim and the steering wheel frame such that the steering wheel rim rotates relative to the steering wheel frame on the plurality of bearings.

11. The automotive vehicle of claim 8 , wherein the steering wheel frame is circular.

12. The automotive vehicle of claim 8 , wherein the steering wheel frame is oval.

13. The automotive vehicle of claim 8 , wherein the emulator is positioned adjacent to the steering wheel assembly.

14. The automotive vehicle of claim 8 , wherein the hub is eccentrically positioned relative to the steering wheel frame.

15. The automotive vehicle of claim 8 , further comprising an instrument panel comprising a groove, wherein the steering wheel assembly fits within the groove when the steering wheel assembly is in the stowed position.

16. The automotive vehicle of claim 15 , wherein the steering wheel rim does not rotate relative to the steering wheel frame when the steering wheel assembly is in the stowed position.

17. The automotive vehicle of claim 15 , wherein the instrument panel further comprises an instrument display, and wherein the steering wheel frame at least partially surrounds the instrument display when the steering wheel assembly is in the stowed position.
