Abstract

An accessory system for a vehicle includes an accessory module, at least one accessory and an attachment member at an interior surface of a vehicle windshield. The at least one accessory comprises a camera having a lens, with the camera being disposed in the accessory module, and the accessory module comprising structure to angle the camera with respect to a windshield facing portion of the accessory module. The camera has a forward field of view through the vehicle windshield when the accessory module is mounted to the attachment member. The accessory system may include a resilient element disposed between the windshield facing portion and the interior surface of the vehicle windshield to cushion and/or seal the accessory module relative to the interior surface when the accessory module is mounted to the attachment member at the interior surface of the vehicle windshield.

Claims

1. An accessory module system for a vehicle, said accessory module system comprising:

an interior rearview mirror assembly;

an accessory module;

at least one accessory housed at least partially in said accessory module, said at least one accessory comprising a camera, said camera having a lens;

an attachment member adhesively attached at an interior surface of a vehicle windshield;

said accessory module being configured to mount to said attachment member;

said accessory module comprising a windshield facing portion that opposes the interior surface of the vehicle windshield when said accessory module is mounted to said attachment member adhesively attached at the interior surface of the vehicle windshield;

said camera being disposed in said accessory module, said accessory module comprising structure to angle said camera with respect to said windshield facing portion of said accessory module, said camera having a forward field of view through the vehicle windshield when said accessory module is mounted to said attachment member;

wherein said lens of said camera is spaced from the interior surface of the vehicle windshield when said accessory module is mounted to said attachment member adhesively attached at the interior surface of the vehicle windshield;

wherein said camera is angled by said structure of said accessory module and with respect to said windshield facing portion to at least partially compensate for the angle of the windshield itself, and wherein a principal axis of the forward field of view of said camera is directed generally at or below horizontal when said accessory module is mounted to said attachment member;

wherein said windshield facing portion of said accessory module comprises a resilient element disposed at the interior surface of the vehicle windshield to at least one of cushion and seal said accessory module relative to the interior surface of the vehicle windshield when said accessory module is mounted to said attachment member adhesively attached at the interior surface of the vehicle windshield;

wherein said accessory module is detachably mounted to said attachment member adhesively attached at the interior surface of the vehicle windshield; and

wherein said interior rearview mirror assembly detachably mounts to at least one (a) said accessory module, (b) a second attachment member at the interior surface of the vehicle windshield, and (c) a header portion of the vehicle.

2. The accessory module system of claim 1, wherein said accessory module comprises a cover and a mounting structure, said cover being attachable to said mounting structure and said mounting structure comprising said windshield facing portion and being configured to mount to said attachment member adhesively attached at the interior surface of the vehicle windshield.

3. The accessory module system of claim 2, wherein said camera is mounted at said mounting structure, and wherein a principal axis of the forward field of view of said camera is directed generally at or below horizontal when said mounting structure is mounted to said attachment member.

4. The accessory module system of claim 2, wherein said resilient element is disposed at the interior surface of the vehicle windshield when said mounting structure is mounted to said attachment member adhesively attached at the interior surface of the vehicle windshield.

5. The accessory module system of claim 1, wherein said resilient element comprises a resilient strip.

6. The accessory module system of claim 5, wherein said resilient strip is disposed at least partially around a perimeter region of said windshield facing portion of said accessory module.

7. The accessory module system of claim 1, wherein said resilient element comprises at least one of a soft material, an elastomeric material and a thermoplastic rubber material.

8. The accessory module system of claim 1, wherein said resilient element is configured to at least partially adapt to the form of the interior surface of the windshield as said accessory module is moved toward and loaded against the interior surface of the windshield during mounting of said accessory module to said attachment member.

9. The accessory module system of claim 1, wherein said camera is associated with at least one of (i) a rain sensing system, (ii) a headlamp control system, (iii) a lane departure detection or warning system, (iv) an adaptive cruise control system, (v) a sign recognition system, (vi) a night vision system, (vii) a pedestrian detection system, (viii) a vehicle classification identification system, (ix) a vehicle compatibility detection system, (x) a pre-crash avoidance system, (xi) an emergency response image capture system, (xii) an environmental detection system, (xiii) an ambient light level detection system, (xiv) a vehicle relative position detection system, (xv) a compass calibration system, (xvi) a global positioning system, and (xvii) an electronic toll collection system.

10. The accessory module system of claim 1, wherein said accessory module comprises cooling means to assist in cooling said at least one accessory.

11. The accessory module system of claim 1, wherein said windshield facing portion of said accessory module includes a light transmitting port, said camera being generally aligned with said light transmitting port with its forward facing field of view through said light transmitting port and through the vehicle windshield.

12. The accessory module system of claim 11, wherein said windshield facing portion provides a dark region at the windshield interface of said accessory module and the vehicle windshield when said accessory module is mounted to said attachment member.

13. The accessory module system of claim 1, wherein said resilient element comprises an interface between said windshield facing portion of said accessory module and the interior surface of the vehicle windshield.

14. The accessory module system of claim 13, wherein said resilient element includes a light transmitting port, said camera being generally aligned with said light transmitting port with its forward facing field of view through said light transmitting port and through the vehicle windshield.

15. The accessory module system of claim 14, wherein said resilient element provides a dark region at the windshield interface of said accessory module and the vehicle windshield when said accessory module is mounted to said attachment member.
