Patent ID: 10080257

Abstract:
Vehicle apparatus includes a glass windshield and a wiper system. A wiper blade has a parking region on the windshield. A deicer selectably provides heat to the parking region. A windshield temperature sensor detects a temperature of the windshield at the parking region. A head-up display is mounted proximate the windshield to display a temperature indicator responsive to the detected temperature. An automatic control circuit is configured to automatically deactivate the deicer when detecting a deiced condition in response to the detected temperature. A manual control element is configured to manually activate and deactivate the deicer. Thus, excessive heating can be avoided based on feedback of the windshield temperature. In addition, the driver is reminded that the deicer is active in a way that simultaneously provides information enabling the driver to independently evaluate the vehicle conditions and to make informed decisions about when to intervene in the automatic operation.
