Abstract

A display system for a vehicle includes a rear view camera constructed and arranged to obtain images external to the vehicle and associated with a rear of the vehicle. At least one side view camera is constructed and arranged to obtain images external to the vehicle and associated with a side of the vehicle. A display is constructed and arranged to display the images to a driver of the vehicle so that the driver can see what is occurring at the rear and the side of the vehicle without using mirrors.

Claims

1. A display system for a vehicle, the vehicle having a windshield, a driver side window and a passenger side window, the system comprising:

a rear view camera constructed and arranged to obtain images external to the vehicle and associated with a rear of the vehicle,

an image receiving area associated with the windshield, and

a controller associated with the rear view camera and constructed and arranged to cause the images to be displayed on the image receiving area so that a driver of the vehicle can see what is occurring at the rear of the vehicle without using a rear view mirror,

at least one projector associated with the controller and constructed and arranged to project the images to the image receiving area so as to be displayed thereon,

at least one side view camera constructed and arranged to obtain images external to the vehicle and associated with a side of the vehicle,

a second image receiving area associated with the vehicle,

wherein the controller is associated with the at least one side view camera and constructed and arranged to cause the images obtained by the side view camera to be displayed on the second image receiving area so that a driver of the vehicle can see what is occurring at the side of the vehicle without using a side view mirror,

at least one additional projector associated with the controller and constructed and arranged to project the images obtained by the side view camera to the second image receiving area so as to be displayed thereon, and

in combination with the vehicle, wherein the second image receiving area is associated with the driver side window and the at least one additional projector is mounted on a driver side door of the vehicle.

2. The system for claim 1, wherein the image receiving area is an electronic display.

3. The system of claim 1, wherein the controller is constructed and arranged to send the voltage to the image receiving area to cause the image receiving area to change from transparent, which allows detailed images to pass through, to translucent, which does not allow detailed images to pass through.

4. The system of claim 1, in combination with the vehicle, wherein the image receiving area is disposed at a top of the windshield and the at least one projector is mounted adjacent to the top of the windshield.

5. The system of claim 1, further comprising a sensor to monitor a position of a head or eyes of the driver, the controller being constructed and arranged to send the images to be displayed on the second image receiving area only when the driver is looking towards the second image receiving area based on the position of the head or eyes.

6. A method of displaying external information to a driver of a vehicle, the vehicle having a windshield and a rear view camera, the method comprising the step of:

providing a first image receiving area,

obtaining images external to the vehicle and associated with a rear of the vehicle from the rear view camera,

displaying the images on the first image receiving area so that a driver of the vehicle can see what is occurring at the rear of the vehicle without using a rear view mirror,

providing a second image receiving area,

obtaining images external to the vehicle and associated with a side of the vehicle from the side view camera,

displaying the images associated with the side of the vehicle on the second image receiving area so that a driver of the vehicle can see what is occurring at the side of the vehicle without using a side view mirror,

wherein the first image receiving area is provided to be associated with the windshield, and the second image receiving area is provided so as to be associated with at least a driver side window of the vehicle,

wherein the first image receiving area is provided as switchable glass that changes from transparent, which allows detailed images to pass through, to translucent, which does not allow detailed images to pass through, upon the application of voltage, the method further comprising;

applying voltage to the switchable glass to make the switchable glass translucent, and thereafter;

projecting the images on the translucent switchable glass so as to be displayed thereon.
