Abstract

A vehicle imaging system includes an imaging sensor, an imaging sensor bracket and an image processor. A vehicle mounting portion of the bracket is configured to mount at a mounting element for a license plate of the vehicle, and a sensor mounting portion of the bracket is angled with respect to the vehicle mounting portion such that the sensor mounting portion extends generally rearwardly when the bracket is fastened at the license plate mounting element. The imaging sensor generates a signal indicative of an image representative of a scene occurring within the field of view. The image processor receives the signal and processes the signal and generates an output signal representative of the imaged scene. The system may include a display, which may display at least one iconistic representation of at least one detected relevant object in response to an output signal generated by the image processor.

Claims

1-34. -34. (canceled)

35. A vehicle imaging system for a vehicle, the vehicle having a license plate mounting portion at a rear portion of the vehicle, said vehicle imaging system comprising:

an imaging sensor having a field of view;

an imaging sensor bracket for mounting said imaging sensor to the vehicle, said imaging sensor bracket comprising a vehicle mounting portion and a sensor mounting portion extending from said vehicle mounting portion;

said vehicle mounting portion being configured to be mounted at a mounting element for a license plate at the license plate mounting portion of the vehicle;

said sensor mounting portion being angled with respect to said vehicle mounting portion such that said sensor mounting portion extends generally rearwardly when said vehicle mounting portion is fastened at the license plate mounting element on the vehicle;

said imaging sensor being disposed at said sensor mounting portion so as to have a generally downward and rearward field of view exterior of the vehicle, said imaging sensor generating a signal indicative of an image representative of a scene occurring within the generally downward and rearward field of view;

an image processor processing said signal and generating an output signal representative of the imaged scene; and

a display operable to display information in response to said output signal of said image processor.

36. The vehicle imaging system of claim 35, wherein said imaging sensor bracket includes a cover element which substantially contains said imaging sensor at said sensor mounting portion of said imaging sensor bracket.

37. The vehicle imaging system of claim 36, wherein said cover element provides an aperture through which said imaging sensor receives light representative of the exterior scene.

38. The vehicle imaging system of claim 35, wherein said sensor mounting portion extends generally rearwardly and generally horizontally when said vehicle mounting portion is fastened at the license plate mounting element on the vehicle.

39. The vehicle imaging system of claim 35, wherein said mounting portion is mounted to a generally vertical panel of the vehicle.

40. The vehicle imaging system of claim 39, wherein said mounting portion is mounted to a generally vertical panel of the vehicle that is recessed at the rear portion of the vehicle, said sensor mounting portion being positioned at an upper region of the recessed panel of the vehicle.

41. The vehicle imaging system of claim 35, wherein said output signal comprises at least one iconistic representation of at least one detected object in the scene.

42. The vehicle imaging system of claim 35, wherein said rearward field of view includes a trailer hitch of the vehicle.

43. The vehicle imaging system of claim 42, wherein said display provides at least one iconistic representation of the trailer hitch of the vehicle and at least one iconistic representation of a hitch of a trailer positioned generally rearward of the vehicle.

44. The vehicle imaging system of claim 43, wherein said at least one iconistic representation of the trailer hitch of the vehicle and said at least one iconistic representation of the hitch of the trailer are displayed as separate icons in said display.

45. The vehicle imaging system of claim 44, wherein said display provides an indication to the driver of the vehicle when the icons representing the trailer hitch of the vehicle and the hitch of the trailer are generally aligned.

46. A vehicle imaging system for a vehicle, the vehicle having a license plate mounting portion at a rear portion of the vehicle, said vehicle imaging system comprising:

an imaging sensor having a field of view;

an imaging sensor bracket for mounting said imaging sensor to the vehicle, said imaging sensor bracket comprising a vehicle mounting portion and a sensor mounting portion extending from said vehicle mounting portion;

said vehicle mounting portion being configured to be mounted at a mounting element for a license plate at the license plate mounting portion of the vehicle;

said sensor mounting portion being angled with respect to said vehicle mounting portion such that said sensor mounting portion extends generally rearwardly when said vehicle mounting portion is fastened at the license plate mounting element on the vehicle;

said imaging sensor bracket includes a cover element which substantially contains said imaging sensor at said sensor mounting portion of said imaging sensor bracket, said cover element providing an opening through which said imaging sensor receives light representative of the exterior scene;

said imaging sensor being disposed at said sensor mounting portion so as to have a generally downward and rearward field of view through said opening and exterior of the vehicle, said imaging sensor generating a signal indicative of an image representative of a scene occurring within the generally downward and rearward field of view; and

an image processor processing said signal and generating an output signal representative of the imaged scene.

47. The vehicle imaging system of claim 46, wherein said sensor mounting portion extends generally rearwardly and generally horizontally when said vehicle mounting portion is fastened at the license plate mounting element on the vehicle.

48. The vehicle imaging system of claim 46, wherein said mounting portion is mounted to a generally vertical panel of the vehicle.

49. The vehicle imaging system of claim 48, wherein said mounting portion is mounted to a generally vertical panel of the vehicle that is recessed at the rear portion of the vehicle, said sensor mounting portion being positioned at an upper region of the recessed panel of the vehicle.

50. The vehicle imaging system of claim 46, wherein said field of view encompasses a trailer hitch of the vehicle.

51. The vehicle imaging system of claim 46, wherein said output signal comprises at least one iconistic representation of at least one detected object in the scene.

52. The vehicle imaging system of claim 46 including a display operable to display information in response to said output signal of said image processor.

53. A vehicle imaging system for a vehicle, the vehicle having a generally vertically oriented license plate mounting portion at a rear portion of the vehicle, said vehicle imaging system comprising:

an imaging sensor having a field of view;

an imaging sensor bracket for mounting said imaging sensor to the vehicle, said imaging sensor bracket comprising a vehicle mounting portion and a sensor mounting portion extending from said vehicle mounting portion;

said vehicle mounting portion being configured to be mounted at a mounting element for a license plate at the generally vertical license plate mounting portion of the vehicle;

said sensor mounting portion being angled with respect to said vehicle mounting portion such that said sensor mounting portion extends generally rearwardly and generally horizontally when said vehicle mounting portion is fastened at the license plate mounting element on the vehicle;

said imaging sensor being disposed at said sensor mounting portion so as to have a generally downward and rearward field of view exterior of the vehicle, said field of view including a trailer hitch of the vehicle, said imaging sensor generating a signal indicative of an image representative of a scene occurring within the generally downward and rearward field of view; and

an image processor processing said signal and generating an output signal representative of the imaged scene.
