ABSTRACT:
A vehicular windshield wiping apparatus has a temperature sensor for sensing temperatures outside of the vehicle, a humidity sensor for sensing humidity outside of the vehicle, windshield wipers moved by a motor, an HVAC control module, and a wiper control module. The wiper control module activates the windshield wipers when the moisture level is at or above a threshold value and the temperature sensor senses a temperature at or below a threshold value. The wiper motor has a first wiper park position and a second wiper park position. The first wiper park position is approximately horizontal and the second wiper park position is at an angle to the first wiper park position, in a heated windshield zone. The second wiper park position allows the wipers to remain free of ice and snow when the outside temperature and moisture levels are beyond specific thresholds or a wiper stalk switch is activated.
