A wiper system is provided and may include a wiper that operates between a parked state and a use state, a motor associated with the wiper that selectively moves the wiper between the parked state and the use state, and a switch that generates a signal identifying whether the wiper is in the parked state or the use state. The wiper system may also include a controller in communication with the switch. The controller may include a second-order filter and a comparator, whereby the controller passes the signal through the second-order filter and the comparator to differentiate between the parked state and the use state. |
