Abstract

A steering wheel and associated control system to execute a corresponding algorithm, the steering wheel including a rim which is rotatable about a first axis to steer a vehicle, and a throttle dial disposed in a surface of the rim. The throttle dial controls a throttle of the vehicle and has a variable output to control an amount of the throttle in proportion to an amount the throttle dial is displaced from a nil output position. A similar brake dial is also provided, and is also disposed in the surface of the rim at another location, thus providing hand operation of a throttle and brake of a vehicle without having to remove one'"'"'s hands from the steering wheel.

Claims

1. A steering wheel, comprising:

a rim that rotates about a first axis to steer a vehicle;

a throttle dial disposed in a surface of the rim to control a throttle of the vehicle, the throttle dial having a variable output to control an amount the throttle is displaced in proportion to an amount the throttle dial is displaced, wherein

the throttle dial pivots about a second axis that is adjustable about a third axis,

the third axis extends in a direction that is radial to the rim and the first axis, and

in a first position, the second axis extends in a direction that is parallel to the first axis, and in a second position, the second axis extends in a direction that is tangential to the rim; and

a sleeve of the rim in which the throttle dial is disposed, wherein

the sleeve rotates about an axis tangential to the rim to vary a position of the throttle dial,

the sleeve forms a contiguous surface with a remainder of the rim about a circumference of the rim,

the rim has a circular shape and the sleeve of the rim forms a portion of the circular shape, and

ends of the sleeve extend around an entire circumference of a cross-section of the rim and coincide with respective edges of the remainder of the rim.

2. The steering wheel according to claim 1, wherein the throttle dial is a throttle wheel which rotates about the second axis.

3. The steering wheel according to claim 1, wherein the throttle dial is disposed in an upper-left portion of the rim when the steering wheel is rotated to a straight vehicle direction.

4. The steering wheel according to claim 1, wherein the surface of the rim in which the dial is disposed faces the first axis about which the rim rotates, such that the throttle dial extends from an interior portion of the rim towards the first axis.

5. The steering wheel according to claim 1, further comprising:

a brake dial disposed in a surface of the rim to control a brake of the vehicle, the brake dial having a variable output to control an amount the brake is displaced in proportion to an amount the brake dial is displaced.

6. The steering wheel according to claim 5, wherein displacement of the brake dial results in a corresponding displacement of the brake via a virtual brake gear according to a virtual brake gear ratio, the virtual brake gear ratio being a ratio between the amount the brake dial is displaced and the amount the brake is displaced.

7. The steering wheel according to claim 6, wherein the brake gear ratio is adjusted based on at least one of:

recorded driving patterns to adapt the brake gear ratio to driving preferences and a speed of the vehicle.

8. The steering wheel according to claim 6, wherein the brake gear ratio is adjusted based on a combination of at least recorded driving patterns to adapt to driving preferences and a speed of the vehicle.

9. The steering wheel according to claim 5, wherein

the brake dial is a brake wheel which rotates about a fourth axis,

the brake wheel rotates about a fifth axis that is substantially perpendicular to the fourth axis such that the fourth axis, about which the brake wheel rotates, is variable from being substantially parallel to the first axis to being substantially perpendicular to the first axis, and

the fifth axis extends in a direction that is radial to the rim and the first axis.

10. The steering wheel according to claim 5, wherein the brake dial is disposed in an upper-right portion of the rim when the steering wheel is rotated to a straight vehicle direction.

11. The steering wheel according to claim 1, wherein the throttle dial is at least partially recessed into the surface of the rim.

12. The steering wheel according to claim 1, wherein:

displacement of the throttle dial results in a corresponding displacement of the throttle via a virtual throttle gear according to a virtual throttle gear ratio, the virtual throttle gear ratio being a ratio between the amount the throttle dial is displaced and the amount the throttle is displaced, and

a value of the virtual throttle gear ratio is adjusted based on at least a speed of the vehicle.

13. The steering wheel according to claim 12, wherein the value of the virtual throttle gear ratio is adjusted based on the speed of the vehicle and at least recorded driving patterns to adapt the virtual throttle gear ratio to driving preferences.

14. The steering wheel according to claim 12, wherein the virtual throttle gear ratio is adjusted based on at least the speed of the vehicle and recorded driving patterns to adapt to driving preferences.

15. A steering wheel, comprising:

a rim that rotates about a first axis to steer a vehicle; and

a brake dial disposed in a surface of the rim to control a brake of the vehicle, the brake dial having a variable output to control an amount the brake is displaced in proportion to an amount the brake dial is displaced, wherein

the brake dial pivots about a fourth axis that is adjustable about a fifth axis,

the fifth axis extends in a direction that is radial to the rim and the first axis, and

in a first position, the fourth axis extends in a direction that is parallel to the first axis, and in a second position, the fourth axis extends in a direction that is tangential to the rim; and

a sleeve of the rim in which the brake dial is disposed, wherein

the sleeve rotates about an axis tangential to the rim to vary a position of the brake dial,

the sleeve forms a contiguous surface with a remainder of the rim about a circumference of the rim,

the rim has a circular shape and the sleeve of the rim forms a portion of the circular shape, and

ends of the sleeve extend around an entire circumference of a cross-section of the rim and coincide with respective edges of the remainder of the rim.
