First Claim
Patent Images
1. A method comprising the steps of:
- (a) receiving a first input signal, wherein the first input initiates a process for causing the operation of a washer motor pump;
(b) determining the position of a rear windshield;
(c) operating the washer motor pump, wherein the washer motor pump operates to dispense a fluid onto the rear windshield, only if the position of the rear windshield is determined to be fully closed;
(d) actuating one of a plurality of operator actuated devices for causing the rear windshield to move from the fully closed position; and
(e) causing the immediate termination of the operation of the washer motor pump in response to the actuating of one of the plurality of operator actuated devices for causing the rear windshield to move.

5. A method comprising the steps of:
-
(a) providing a vehicle comprising;
(1) a rear-facing side;
(2) a rear windshield; and
, (3) an aperture formed in the rear-facing side;
wherein the rear windshield is positional into a fully closed position where the rear windshield encloses the aperture and an open position where the rear windshield does not enclose the aperture;(b) providing a rear wiper-washer system comprising;
(1) a rear wiper arm that is operable to at least partially remove debris from the rear windshield; and
, (2) a fluid supply device that is operable to supply a fluid to the rear windshield;(c) providing a control system comprising;
(1) a rear windshield position switch for use in generating a signal indicating the position of the rear windshield;
(2) a fluid supply switch for use in generating an input signal to operate the fluid supply device to supply the fluid to the rear windshield; and
(3) a windshield operator actuatable electrical switch for use in generating an input signal to position the rear windshield into the open position;(d) activating the fluid supply switch to generate the input signal to operate the fluid supply device to supply the fluid to the rear windshield; (e) determining with the control system the position of the rear windshield; and
,(f) sending an output signal with the control system to operate the fluid supply device to supply the fluid to the rear windshield only if the control system first determines that the rear windshield is in the fully closed position; (g) actuating the windshield operator actuatable electrical switch; and (h) terminating the sending of the output signal to operate the fluid supply device in response to the actuating of the windshield operator actuatable electrical switch. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A method comprising the steps of:
-
(a) providing a vehicle comprising;
(1) a rear-facing side;
(2) a rear windshield; and
, (3) an aperture formed in the rear-facing side;
wherein the rear windshield is positional into a fully closed position where the rear windshield encloses the aperture and an open position where the rear windshield does not enclose the aperture;(b) providing a rear wiper-washer system comprising;
(1) a rear wiper arm that is oscillateable to at least partially remove debris from the rear windshield; and
, (2) a fluid supply device that is operable to supply a fluid to the rear windshield;(c) providing a control system comprising;
(1) a rear windshield position switch for use in generating a signal indicating the position of the rear windshield;
(2) a fluid supply switch for use in generating an input signal to operate the fluid supply device to supply the fluid to the rear windshield; and
, (3) a rear windshield wiper switch for use in generating an input signal to oscillate the rear wiper arm to remove debris from the rear windshield;(d) providing a windshield operator actuatable electrical switch for use in generating an input signal to position the rear windshield into the open position; (e) activating the fluid supply switch to generate the input signal to operate the fluid supply device to supply the fluid to the rear windshield; (f) activating the rear windshield wiper switch to generate the input signal to oscillate the rear wiper arm to remove debris from the rear windshield; (g) determining with the control system the position of the rear windshield; wherein step (g) comprises the steps of; generating the input signal, using the windshield operator actuatable electrical switch, to position the rear windshield into the open position; and determining that the rear windshield is in the open position in response to the windshield operator actuatable electrical switch generating the input signal to position the rear windshield into the open position; (h) sending an output signal with the control system to operate the fluid supply device to supply the fluid to the rear windshield only if the control system first determines that the rear windshield is in the fully closed position; (i) sending an output signal with the control system to oscillate the rear wiper arm to remove debris from the rear windshield only if the control system first determines that the rear windshield is in the fully closed position; and (j) terminating immediately the sending of the output signal to operate the fluid supply device in response to the generating of the input signal to position the rear windshield into the open position. - View Dependent Claims (17, 18, 19, 20)
