Embodiment Construction

[0054] now refer to figure 1 The vehicle 10 may provide a lane departure warning (LDW) sensor system 12 positioned at a top center position on the windshield 14 of the vehicle 10 . Generally, LDW sensor system 12 may provide anti-glare housing 16 positioned around the lens of camera 18, wherein camera 18 may be pointed at the road ahead of vehicle 10 along boresight 20 to monitor the position of lane markings (not shown) on the road. . Anti-glare cover 16 may be constructed, for example, from a dark colored injection molded thermoplastic material with the surface coated or textured to reduce reflections.

[0055] Temporary reference Figure 4 The anti-glare cover 16 may include a lower triangular anti-glare panel 22 extending from the windshield 14 to the lower edge of the camera 18 and an upper anti-glare panel 24 extending from the upper edge of the camera 18 to the windshield 14 . The upper anti-glare panel 24 and the lower anti-glare panel 22 are angled away from each o...

Abstract

A heater system for clearing moisture (frozen and liquid) from a windshield (14) around a through-windshield vehicle sensor (18) provides a chamber between the sensor and the windshield containing air that may be heated by a chamber supported heating element (30, 51). The warm air within the chamber applies heat over the windshield in the critical viewing area (26) without obstructing the sensor (18).

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 095,388, filed December 22, 2014, and U.S. Provisional Application No. 62 / 196,000, filed July 23, 2015, both of which are incorporated by reference into this article. technical field [0003] The present invention relates generally to vehicle systems, and in particular to advanced vehicle sensor systems such as lane departure sensors. Background technique [0004] Vehicle systems for determining whether a vehicle is staying within a road lane and providing an alert to the driver if not (lane departure alert) are being developed as part of current vehicle safety equipment. [0005] Sensors for lane departure warning (LDW) systems can include cameras mounted in the cabin, usually between the center mirror and the windshield. From this position, the camera is positioned such that its field of view is directed towards the road ahead of the vehicle...
