Systems and methods for calibrating a windshield wiper system

1. A method of calibrating a windshield wiper system, the method comprising:

moving a wiper arm, of the windshield wiper system, at a first rate of speed towards at least one physical boundary and within at least a portion of a full range of motion defined by the at least one physical boundary;

determining a position of the wiper arm after movement at the first rate of speed when it the wiper arm contacts the at least one physical boundary;

moving the wiper arm, of the windshield wiper system, at a second rate of speed towards the at least one physical boundary, wherein the second rate of speed is different than the first rate of speed;

determining a position of the wiper arm after movement at the second rate of speed towards the at least one physical boundary;

defining, based on each determined position of the wiper arm, an operating range of motion for the wiper arm that is shorter than the full range of motion; and

setting the wiper arm to operate within the defined operating range of motion.

2. The method in accordance with claim 1 , wherein defining an operating range of motion comprises determining at least one range limit for the wiper arm, wherein the at least one range limit is offset from the determined position of the wiper arm by a predetermined distance.

3. The method in accordance with claim 2 , wherein determining at least one range limit comprises:

setting a first range limit for the wiper arm, wherein the first range limit is offset from an upper limit of the full range of motion by the predetermined distance; and

setting a second range limit for the wiper arm, wherein the second range limit is offset from a lower limit of the full range of motion by the predetermined distance.

4. The method in accordance with claim 2 , wherein setting the wiper arm comprises storing the at least one range limit within a controller associated with the wiper arm.

5. The method in accordance with claim 1 , wherein determining a position of the wiper arm comprises:

moving the wiper arm towards the at least one physical boundary to initiate contact therewith;

moving the wiper arm away from the at least one physical boundary, the moving steps defining a contact cycle;

performing multiple contact cycles, wherein positional data is obtained from each contact cycle; and

determining the position of the wiper arm based on an analysis of the positional data.

6. The method in accordance with claim 1 , wherein determining a position of the wiper arm comprises:

determining a position of the wiper arm as it is moved at the first rate of speed towards a first position defined within the full range of motion, wherein the first position is offset from the at least one physical boundary by a predetermined distance; and

determining a position of the wiper arm as it is moved at the second rate of speed from the first position towards the at least one physical boundary, wherein the second rate of speed is less than the first rate of speed.

7. The method in accordance with claim 1 , wherein determining a position of the wiper arm comprises receiving a feedback response from a motor configured to operate the wiper arm, the feedback response indicating contact has been initiated with the at least one physical boundary.

8. A method of calibrating a windshield wiper system, the method comprising:

moving a wiper arm, of the windshield wiper system, at a first rate of speed within at least a portion of a full range of motion that includes an upper limit defined by a first physical boundary and a lower limit defined by a second physical boundary;

determining a rotational position of the wiper arm after movement at the first rate of speed when it contacts the first physical boundary or the second physical boundary;

moving the wiper arm, of the windshield wiper system, at a second rate of speed towards one of the first physical boundary and the second physical boundary;

determining a rotational position of the wiper arm after movement at the second rate of speed when it contacts the first physical boundary or the second physical boundary;

defining, based on the each determined rotational position of the wiper arm, an operating range of motion for the wiper arm that is shorter than the full range of motion; and

setting the wiper arm to operate within the defined operating range of motion.

9. The method in accordance with claim 8 , wherein defining an operating range of motion comprises determining at least one range limit for the wiper arm, wherein the at least one range limit is offset from the determined degree of rotation by a predetermined number of degrees.

10. The method in accordance with claim 9 , wherein determining at least one range limit comprises:

setting a first range limit for the wiper arm, wherein the first range limit is offset from the upper limit of the full range of motion by the predetermined number of degrees; and

setting a second range limit for the wiper arm, wherein the second range limit is offset from the lower limit of the full range of motion by the predetermined number of degrees.

11. The method in accordance with claim 9 , wherein setting the wiper arm comprises storing the at least one range limit within a controller associated with the wiper arm.

12. The method in accordance with claim 8 , wherein determining a position of the wiper arm comprises:

moving the wiper arm towards the first physical boundary or the second physical boundary to initiate contact therewith;

moving the wiper arm away from the first physical boundary or the second physical boundary, the moving steps defining a contact cycle;

performing multiple contact cycles, wherein positional data is obtained from each contact cycle; and

determining the rotational position of the wiper arm based on an analysis of the positional data.

13. The method in accordance with claim 8 , wherein determining a rotational position of the wiper arm comprises:

determining a rotational position of the wiper arm after moving the wiper arm at the first rate of speed towards a first position defined within the full range of motion, wherein the first position is offset from one of the first physical boundary or the second physical boundary by a predetermined degree of rotation; and

determining a rotational position of the wiper arm after moving the wiper arm at the second rate of speed from the first position towards the one of the first physical boundary or the second physical boundary, wherein the second rate of speed is less than the first rate of speed.

14. The method in accordance with claim 8 , wherein determining a rotational position of the wiper arm comprises receiving a feedback response from a motor configured to operate the wiper arm, the feedback response indicating contact has been initiated with the first physical boundary or the second physical boundary.
