Abstract

A vision system for a vehicle includes a forward viewing camera disposed at a mirror head of an interior rearview mirror assembly of the vehicle and having a forward field of view through the windshield of the vehicle. A sensor is disposed at the mirror head and determines a change in position of the mirror head relative to a mirror mount of the mirror assembly when the vehicle driver adjusts the mirror head. A control includes a processor operable to process image data captured by the forward viewing camera. Responsive to determination by the sensor of a change of position of the forward viewing camera relative to the mirror mount, the control selects an active sub-array of photosensors to provide an effective field of view of the forward viewing camera. The processor processes image data captured by the active sub-array of photosensors for a driver assistance system of the vehicle.

Dependent claims

A vision system for a vehicle, said vision system comprising:

an interior rearview mirror assembly comprising a mirror head and a mirror mount, wherein said mirror mount is fixedly attached at an interior portion of the vehicle, and wherein said mirror head is pivotally mounted at said mirror mount and is adjustable relative to said mirror mount to adjust a rearward field of view of a driver of the vehicle when viewing a mirror reflective element of said mirror head;
a forward viewing camera disposed at said mirror head of said interior rearview mirror assembly and having a forward field of view through the windshield of the vehicle, wherein said forward viewing camera comprises a photosensor array having multiple columns and rows of photosensor elements;
wherein the forward field of view of said forward viewing camera adjusts in tandem with adjustment of said mirror head;
a sensor disposed at said mirror head and operable to determine a change in position of said mirror head relative to said mirror mount;
a control comprising a processor operable to process image data captured by said forward viewing camera;
wherein, responsive to determination by said sensor of a change of position of said mirror head relative to said mirror mount, said control selects an active sub-array of photosensors to provide an effective field of view of said forward viewing camera;
wherein said processor processes image data captured by the active sub-array of photosensors for a driver assistance system of the vehicle;
and
wherein the active sub-array of photosensors comprises a subset of photosensors of said photosensor array that is less than the entirety of the rows and columns of photosensor elements of said photosensor array.

A vision system for a vehicle, said vision system comprising:

an interior rearview mirror assembly comprising a mirror head and a mirror mount, wherein said mirror mount is fixedly attached at an interior portion of the vehicle, and wherein said mirror head is pivotally mounted at said mirror mount and is adjustable relative to said mirror mount to adjust a rearward field of view of a driver of the vehicle when viewing a mirror reflective element of said mirror head;
a forward viewing camera disposed at said mirror head of said interior rearview mirror assembly and having a forward field of view through the windshield of the vehicle, wherein said forward viewing camera comprises a photosensor array having multiple columns and rows of photosensor elements;
wherein the forward field of view of said forward viewing camera adjusts in tandem with adjustment of said mirror head;
a sensor disposed at said mirror head and operable to determine a change in position of said mirror head relative to said mirror mount;
a control comprising a processor operable to process image data captured by said forward viewing camera;
wherein, responsive to determination by said sensor of a change of position of said mirror head relative to said mirror mount, said control selects an active sub-array of photosensors to provide an effective field of view of said forward viewing camera;
wherein said control adjusts the active sub-array of photosensors to accommodate for movement of said forward viewing camera relative to said mirror mount based on the determined change of position of said mirror head when the driver adjusts the rearward field of view provided by said interior rearview mirror assembly;
wherein said processor processes image data captured by the active sub-array of photosensors for a driver assistance system of the vehicle;
wherein the active sub-array of photosensors comprises a subset of photosensors of said photosensor array that is less than the entirety of the rows and columns of photosensor elements of said photosensor array;
and
wherein said processor does not process image data captured by photosensors that are not part of the active sub-array of photosensors.

8 more elements

A vision system for a vehicle, said vision system comprising:

an interior rearview mirror assembly comprising a mirror head and a mirror mount, wherein said mirror mount is fixedly attached at an interior portion of the vehicle, and wherein said mirror head is pivotally mounted at said mirror mount and is adjustable relative to said mirror mount to adjust a rearward field of view of a driver of the vehicle when viewing a mirror reflective element of said mirror head;
a rearward viewing camera configured to be disposed at a vehicle and having a rearward field of view exterior of the vehicle;
a forward viewing camera disposed at said mirror head of said interior rearview mirror assembly and having a forward field of view through the windshield of the vehicle, wherein said forward viewing camera comprises a photosensor array having multiple columns and rows of photosensor elements;
wherein the forward field of view of said forward viewing camera adjusts in tandem with adjustment of said mirror head;
a sensor disposed at said mirror head and operable to determine a change in position of said mirror head relative to said mirror mount;
a control comprising a processor operable to process image data captured by said rearward viewing camera and said forward viewing camera;
wherein, responsive to determination by said sensor of a change of position of said mirror head relative to said mirror mount, said control selects an active sub-array of photosensors to provide an effective field of view of said forward viewing camera;
wherein said processor processes image data captured by the active sub-array of photosensors for a driver assistance system of the vehicle;
wherein the active sub-array of photosensors comprises a subset of photosensors of said photosensor array that is less than the entirety of the rows and columns of photosensor elements of said photosensor array;
wherein said processor does not process image data captured by photosensors that are not part of the active sub-array of photosensors;
and
a display disposed operable to display video images derived from image data captured by said rearward viewing camera.
