Abstract

Claims (47)

1 . An orientationally flexible bump sensor comprising:

at least one bump sensor mounted to a vehicle, said at least one bump sensor comprising at least two axes of measurement; and

a computer processor configured to:

evaluate said at least two axes of measurement to determine which axis of said at least two axes of measurement has a highest magnitude vector;

determine a gain value to cause said highest magnitude vector to be approximately 1 g; and

assign said gain value to said axis with said highest magnitude vector, such that said gain value is applied to each measurement generated by said axis with said highest magnitude vector, such that said orientationally flexible bump sensor provides accurate measurement results regardless of an orientation of said orientationally flexible bump sensor with respect to a ground plane.

2 . The orientationally flexible bump sensor of claim 1 , further comprising:

said at least one bump sensor mounted to said vehicle at an orientation such that neither of said at least two axes of measurement are perpendicular to said ground plane.

3 . The orientationally flexible bump sensor of claim 1 , wherein said at least one bump sensor is mounted to a swingarm of said vehicle.

4 . The orientationally flexible bump sensor of claim 1 , further comprising:

said at least one bump sensor placed in a calibration state prior to said evaluation of said at least two axes of measurement by said computer processor.

5 . The orientationally flexible bump sensor of claim 1 , wherein said computer processor is a microprocessor of said at least one bump sensor.

6 . The orientationally flexible bump sensor of claim 1 , wherein said computer processor is a microprocessor of a suspension controller.

9 . A method for calibrating an orientationally flexible bump sensor, said method comprising:

generating at least two axes of measurement from a bump sensor mounted to a vehicle;

evaluating said at least two axes of measurement to determine which axis of said at least two axes of measurement has a highest magnitude vector;

determining a gain value to cause said highest magnitude vector to be approximately 1 g; and

assigning said gain value to said axis with said highest magnitude vector, such that said gain value is applied to every measurement generated by said axis with said highest magnitude vector, such that said orientationally flexible bump sensor provides accurate measurement results regardless of an orientation of said orientationally flexible bump sensor with respect to a ground plane.

10 . The method of claim 9 , further comprising:

mounting said bump sensor to said vehicle at an orientation such that neither of said at least two axes of measurement are perpendicular to said ground plane.

11 . The method of claim 9 , further comprising:

mounting said bump sensor to a swingarm of said vehicle.

12 . The method of claim 9 , further comprising:
