Abstract

A method for tilting a seat of a vehicle based on a first threshold_low and a first threshold_high for a first parameter of the vehicle and a second threshold_low and a second threshold_high for a second parameter of the vehicle. The tilt angle of the seat is increased if the first parameter≧first threshold_low and the second parameter≧second threshold_high or if the first parameter≧first threshold_high and the second parameter≧second threshold_low.

Claims

1. A method for tilting a seat of a vehicle, comprising:

sensing a first parameter of the vehicle;

sensing a second parameter of the vehicle;

retrieving a first threshold_low for the first parameter, a first threshold_high for the first parameter, a second threshold_low for the second parameter, and a second threshold_high for the second parameter, wherein the first threshold_low<

first threshold_high and wherein the second threshold_low<

second threshold_high; and

increasing the tilt angle of the seat if the first parameter≧

first threshold_low and the second parameter≧

second threshold_high or if the first parameter≧

first threshold_high and the second parameter≧

second threshold_low.

2. The method of claim 1 further comprising maintaining the tilt angle of the seat if first threshold_low≦

first parameter<

first threshold_high and second threshold_low≦

second parameter<

second threshold_high.

3. The method of claim 2 wherein said sensing a first parameter includes sensing a steering angle of a steering device of the vehicle.

4. The method of claim 3 wherein said sensing a second parameter includes sensing a speed of the vehicle.

5. The method of claim 2 wherein said sensing a first parameter includes sensing a lateral acceleration of the vehicle.

6. The method of claim 5 wherein said sensing a second parameter includes sensing a yaw rate of the vehicle.

7. The method of claim 1 further comprising retrieving a first threshold_med for the first parameter and a second threshold_med for the second parameter, wherein the first threshold_low<

first threshold_med<

first threshold_high and wherein the second threshold_low<

second threshold_med<

second threshold_high.

8. The method of claim 7 further comprising increasing the tilt angle of the seat if the first parameter≧

first threshold_med and the second parameter≧

second threshold_med.

9. The method of claim 8 wherein said sensing a first parameter includes sensing a steering angle of a steering device of the vehicle.

10. The method of claim 9 wherein said sensing a second parameter includes sensing a speed of the vehicle.

11. The method of claim 8 wherein said sensing a first parameter includes sensing a lateral acceleration of the vehicle.

12. The method of claim 11 wherein said sensing a second parameter includes sensing a yaw rate of the vehicle.

13. The method of claim 1 wherein said retrieving includes retrieving from a memory device.
