Abstract

A method and system for automatically adjusting a driver seat, steering wheel, pedals, mirrors, and other components of a vehicle, based on information about the size of the driver. The method uses basic information about the driver'"'"'s size—including standing height, sitting height, and gender—in a model which estimates all anthropometric data for the driver. The anthropometric data for the driver—including upper and lower arm and leg lengths, torso length, and other dimensions—is used in inverse kinematic calculations to determine optimal positions and orientations for the adjustable components of the vehicle'"'"'s cockpit. The method then pre-adjusts the components before the driver enters the vehicle, and makes compatible adjustments to the mirrors and other components if the driver adjusts the driver seat.

Claims

1. A method for automatically adjusting positions of a driver seat and other components of a vehicle, said method comprising:

providing data about an interior space of the vehicle where a driver is seated;

providing a plurality of attributes about the driver;

using the attributes about the driver in an anthropometric estimator to estimate body dimensions for the driver;

using the body dimensions for the driver and the data about the interior space of the vehicle to calculate optimal positions of the driver seat and the other components; and

adjusting the positions of the driver seat and the other components to the optimal positions.

2. The method of claim 1 wherein the positions of the driver seat include seat fore-aft position, seat cushion elevation and recline angle, seat back recline angle, and lumbar support position.

3. The method of claim 1 wherein the other components include a headrest, outside rearview mirrors, an inside rearview mirror, a shoulder belt height adjuster, a steering wheel and column, and accelerator and brake pedals.

4. The method of claim 1 wherein providing a plurality of attributes about the driver includes providing standing height, sitting height, and gender of the driver.

5. The method of claim 1 wherein providing a plurality of attributes about the driver includes first identifying the driver from a database of pre-defined drivers, and looking up the attributes from the database.

6. The method of claim 1 wherein providing a plurality of attributes about the driver includes measuring the attributes with one or more sensors when the driver is unidentified.

7. The method of claim 1 wherein using the attributes about the driver in an anthropometric estimator to estimate body dimensions for the driver includes using the attributes in a first order or second order regression model derived from using an anthropometric database of a general population to estimate the body dimensions.

8. The method of claim 1 wherein using the body dimensions for the driver and the data about the interior space of the vehicle to calculate optimal positions of the driver seat and the other components includes using a set of inverse kinematic calculations.

9. The method of claim 8 wherein using a set of inverse kinematic calculations includes calculating the position of the driver seat, ankle, knee, and hip angles, and leg reach, using lower extremity body dimensions as input.

10. The method of claim 8 wherein using a set of inverse kinematic calculations includes calculating driver elbow and shoulder angles, and arm reach, using upper extremity body dimensions as input.

11. The method of claim 8 wherein using a set of inverse kinematic calculations includes calculating a driver torso angle, and seat back recline angle, using leg reach and arm reach as input.

12. The method of claim 1 further comprising readjusting the other components in response to an adjustment of the driver seat by the driver.

13. A method for automatically adjusting positions of a driver seat and other components of a vehicle, said method comprising:

providing data about an interior space of the vehicle where a driver is seated;

providing a plurality of attributes about the driver, including standing height, sitting height, and gender;

using the attributes about the driver in a first or second order anthropometric estimator model to estimate body dimensions for the driver;

using the body dimensions for the driver and the data about the interior space of the vehicle to calculate optimal positions of the driver seat and the other components;

adjusting the positions of the driver seat and the other components to the optimal positions; and

readjusting the other components in response to an adjustment of the driver seat by the driver.

14. A system for automatically adjusting positions of adjustable components in a vehicle, said adjustable components including a driver seat and one or more of a headrest, outside rearview mirrors, an inside rearview mirror, a shoulder belt height adjuster, a steering wheel and column, and accelerator and brake pedals, said system comprising:

a driver identification sub-system for determining attributes about the driver; and

a controller in communication with the driver identification sub-system and the adjustable components, said controller being configured to receive the attributes about the driver from the driver identification sub-system, estimate body dimensions for the driver, calculate optimal positions of the adjustable components, and command the adjustable components to move to the optimal positions.

15. The system of claim 14 wherein the driver identification sub-system determines the attributes about the driver, including standing height, sitting height, and gender, either by identifying the driver from a database of pre-defined drivers, or by measuring the attributes.

16. The system of claim 14 wherein the controller estimates body dimensions for the driver using an anthropometric estimator module, including a first or second order anthropometric model.

17. The system of claim 14 wherein the controller calculates optimal positions of the adjustable components using an inverse kinematic calculation module.

18. The system of claim 17 wherein the inverse kinematic calculation module in the controller includes a routine for calculating the optimal position of the driver seat, ankle, knee, and hip angles, and leg reach, using lower extremity body dimensions as input.

19. The system of claim 17 wherein the inverse kinematic calculation module in the controller includes a routine for calculating optimal driver elbow and shoulder angles, and arm reach, using upper extremity body dimensions as input.

20. The system of claim 17 wherein the inverse kinematic calculation module in the controller includes a routine for calculating an optimal driver torso angle, and seat back recline angle, using leg reach and arm reach as input.
