Summary:

The objective of this paper is to introduce to the trucking industry an innovative approach that will significantly increase the life and reliability of their windshield wiper systems.The endurance of a windshield wiper system is dramatically reduced when operated in the intermittent mode. The motor's integral commutator switch opens a highly inductive load and closes a short circuit across the winding during each cycle. Using the commutator switch as a sensor allows control by an expendable relay to extend system life and enhance maintainability.The sensor can also be used for "Wiper System Guard" or "Freeze Control" to detect non-rotation for quick, reliable shut down, which eliminates Thermal Cycling. Another feature requires the operator to control "Reset" for safe "Start-Up."To simplify the determination of the wipers' repetition rate, a "switch" control technique is employed to increase operator functionality based on "need" to see through a windshield
