Abstract

A system and method for detecting the position of the head and/or eye of a driver of an automobile and automatically adjusting the position of the steering wheel based on the head and/or eye position in order to provide the driver with an optimized view of the instrumentation panel and road. The system and method utilizes the vehicle parameters, driver parameters, and various settings to determine the proper position of the steering wheel including the height, proximity to driver, and tilt angle of the steering wheel. The system may also adjust the height and/or length of the steering column in order to adjust and provide the proper position of the steering wheel.

Claims

1. An automatically-adjusting steering wheel system comprising:

a steering wheel assembly;

a head position sensor configured and arranged to detect a position of a head of a driver of a vehicle; and

a master controller in communication with the head position sensor and the adjustable steering wheel assembly, wherein the master controller is configured to;

receive input from the steering wheel assembly;

receive input from the head position sensor;

determine an optimal line of sight of the driver defined by an interception point based on an intersection of;

(a) an arc defined by a plurality of top points of the steering wheel assembly, and

(b) a straight line defined by a position of at least one eye of the driver and a top point of an instrumentation panel;

adjust the steering wheel assembly based on the input from the steering wheel assembly and the input from the head position sensor; and

adjust the steering wheel assembly based on the optimal line of sight to provide the driver with unobstructed views of the instrumentation panel and a road.

2. The system according to claim 1, wherein the steering wheel assembly includes:

a steering wheel;

a steering column; and

an adjustment assembly configured to adjust the position of the steering wheel.

3. The system according to claim 2, wherein the position of the steering wheel includes at least one of the height, tilt angle, and proximity to driver.

4. The system according to claim 1, wherein the master controller, in being configured to adjust the steering wheel assembly, is configured to send a signal to the steering wheel assembly including information indicating a tilt angle of the steering wheel, height of the steering wheel and proximity of the steering wheel to the driver.

5. The system according to claim 1, wherein the master controller is further configured to determine the position of the head of the driver based on an angle of a side view mirror.

6. The system according to claim 1, wherein the head position sensor is further configured to determine the position of the at least one eye of the driver of the vehicle.

7. A method, for adjusting the position of a steering wheel system automatically, comprising:

receiving input from a steering wheel assembly, wherein the input includes information indicating a position of a steering wheel of the steering wheel assembly;

receiving input from a head position sensor, wherein the input indicates a position of a head of a driver;

determining an optimal line of sight of the driver defined by an interception point based on an intersection of;

(a) an arc defined by a plurality of top points of the steering wheel assembly, and

(b) a straight line defined by a position of at least one eye of the driver and a top point of an instrumentation panel; and

adjusting the steering wheel assembly based on the input from the steering wheel assembly, the input from the head position sensor, and the optimal line of sight to provide the driver with unobstructed views of the instrumentation panel and a road.

8. The method according to claim 7, wherein the position of the steering wheel includes at least one of the height, tilt angle, and proximity to driver.

9. The method according to claim 7, further comprising sending a signal to the steering wheel assembly including information indicating a tilt angle of the steering wheel, height of the steering wheel and proximity of the steering wheel to the driver.

10. The method according to claim 7, further comprising determining the position of the head of the driver based on an angle of a side view mirror.

11. The method according to claim 7, wherein the input from the head position sensor further indicates the position of the at least one eye of the driver of the vehicle.

12. A non-transitory computer-readable medium having stored thereon computer-executable instructions that, when executed by a processor, cause the processor to perform a method, comprising:

receiving input from a steering wheel assembly;

receiving input from a head position sensor;

determining an optimal line of sight of the driver defined by an interception point based on an intersection of;

(a) an arc defined by a plurality of top points of the steering wheel assembly, and

(b) a straight line defined by a position of at least one eye of the driver and a top point of an instrumentation panel; and

adjusting the steering wheel assembly based on the input from the steering wheel assembly, the input from the head position sensor, and the optimal line of sight to provide the driver with unobstructed views of the instrumentation panel and a road.

13. The non-transitory computer-readable medium according to claim 12, wherein the input from the steering wheel assembly includes information indicating a position of a steering wheel of the steering wheel assembly.

14. The non-transitory computer-readable medium according to claim 13, further comprising adjusting the tilt of the steering wheel to provide the driver the unobstructed view of the instrumentation panel and the road.

15. The non-transitory computer-readable medium according to claim 12, wherein the input from the head position sensor indicates the position of the head of the driver.

16. The non-transitory computer-readable medium according to claim 12, wherein the input from the head position sensor indicates the position of the at least one eye of the driver.
