Motor vehicle back-up system
First Claim
1. A method for aiding a driver in backing a motor vehicle, comprising the steps of:
- detecting when a motor vehicle is placed in a reverse direction;
visually displaying an image of an area at a rear of the motor vehicle provided by a camera on a monitor when the motor vehicle is placed in the reverse direction, wherein the monitor is positioned to be visually accessible by a driver of the motor vehicle;
sensing a distance to an object that is within a path of the motor vehicle with a radar sensor when the motor vehicle is placed in the reverse direction;
providing a warning when the object is within a predetermined collision distance; and
detecting when the motor vehicle is placed in a forward direction, wherein the display of the image is discontinued when the motor vehicle is placed in the forward direction.

Abstract
A back-up system for aiding a driver in backing a motor vehicle performs a number of functions when a motor vehicle is placed in a reverse direction. Initially, an image of an area at the rear of the motor vehicle provided by a camera is visually displayed on a monitor, which is positioned so as to be visually accessible by a driver of the motor vehicle. Then, a distance to an object that is within a path of the motor vehicle is sensed with a radar sensor. Next, a warning is provided when the object is within a predetermined collision distance. Finally, when the motor vehicle is placed in a forward direction, the display of the image on the monitor is discontinued.

8. A back-up system for a motor vehicle, comprising:
-
a camera located to view an area at a rear of a motor vehicle;
a processor coupled to the camera;
a monitor coupled to the processor, the monitor displaying images provided by the camera;
a radar sensor coupled to the processor, wherein the radar sensor provides a radar signal that is used to sense a distance to an object that is within a path of the motor vehicle when the motor vehicle is placed in a reverse direction; and
a memory subsystem coupled to the processor, the memory subsystem storing code that when executed by the processor causes the processor to perform the steps of;
detecting when the motor vehicle is placed in the reverse direction;
visually displaying an image of the area at the rear of the motor vehicle on the monitor when the motor vehicle is placed in the reverse direction, wherein the monitor is positioned to be visually accessible by a driver of the motor vehicle;
sensing a distance to an object that is within a path of the motor vehicle with the radar sensor when the motor vehicle is placed in the reverse direction;
providing a warning when the object is within a predetermined collision distance; and
detecting when the motor vehicle is placed in a forward direction, wherein the display of the image is discontinued when the motor vehicle is placed in the forward direction. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A back-up system for a motor vehicle, comprising:
-
a camera located to view an area at a rear of a motor vehicle;
a processor coupled to the camera;
a monitor coupled to the processor, the monitor displaying images provided by the camera;
a radar sensor coupled to the processor, wherein the radar sensor provides a radar signal that is used to sense a distance to an object that is within a path of the motor vehicle when the motor vehicle is placed in a reverse direction;
a speaker coupled to the processor; and
a memory subsystem coupled to the processor, the memory subsystem storing code that when executed by the processor causes the processor to perform the steps of;
detecting when the motor vehicle is placed in the reverse direction;
visually displaying an image of the area at the rear of the motor vehicle on the monitor when the motor vehicle is placed in the reverse direction, wherein the monitor is positioned to be visually accessible by a driver of the motor vehicle;
sensing a distance to an object that is within a path of the motor vehicle with the radar sensor when the motor vehicle is placed in the reverse direction;
providing an audible warning over the speaker when the object is within a predetermined collision distance; and
detecting when the motor vehicle is placed in a forward direction, wherein the display of the image is discontinued when the motor vehicle is placed in the forward direction. - View Dependent Claims (16, 17, 18, 19)
