Abstract

An object exterior to a vehicle can be detected, and an augmented image of the detected object can be output to a vehicle display device, wherein at least one of dimensions and a motion of the augmented image is adjusted based on an environmental condition and physical attribute of the detected object including at least one of a speed, an acceleration, a location, and a direction of the detected object.

First claim

What is claimed is:

1. A method, comprising:
detecting an object exterior to a vehicle;
outputting an augmented image of the detected object to a vehicle display device, wherein at least one of dimensions and a motion of the augmented image is adjusted based on an environmental condition and physical attribute of the detected object including at least one of a speed, an acceleration, a location, and a direction of the detected object;
determining a risk of collision posed by the detected object based on a speed, an acceleration, a time to collision, a distance of the object, and a plurality of risk classifiers, wherein the risk classifiers include graphs specifying respective distance, speed, and acceleration risks;
determining a compensated risk of collision based on a plurality of multiplier factors and the determined risk, each of the multiplier factors corresponding to a different environmental condition in a plurality of environmental conditions; and
adjusting the dimensions of the image of the detected object based on the compensated risk of collision.

2. The method of claim 1 , wherein the environmental condition includes at least one of traffic density, a road type, and a visibility.

3. The method of claim 1 , wherein the display device includes a vehicle mirror, the method further comprising projecting the augmented image on the vehicle mirror, wherein the augmented image is superimposed on a reflected image of the detected object in the mirror.

4. The method of claim 1 , further comprising determining the risk based on the physical attribute of the detected object and a risk classifier.

5. The method of claim 1 , further comprising adjusting the motion of the image of the detected object by blinking the image at a frequency, wherein the frequency is based on the determined risk.

6. A system, comprising a processor and a memory, the memory storing instructions executable by the processor to:
detect an object exterior to a vehicle;
output an augmented image of the detected object to a vehicle display device, wherein at least one of dimensions and a motion of the augmented image is adjusted based on an environmental condition and physical attribute of the detected object including at least one of a speed, an acceleration, a location, and a direction of the detected object;
determine a risk of collision posed by the detected object based on a speed, an acceleration, a time to collision, a distance of the object, and a plurality of risk classifiers, wherein the risk classifiers include graphs specifying respective distance, speed, and acceleration risks;
determine a compensated risk of collision based on a plurality of multiplier factors and the determined risk, each of the multiplier factors corresponding to a different environmental condition in a plurality of environmental conditions; and
adjust the dimensions of the image of the detected object based on the compensated risk of collision.

7. The system of claim 6 , wherein the environmental condition includes at least one of traffic density, a road type, and a visibility.

8. The system of claim 6 , wherein the display device includes a vehicle mirror, and the instructions include further instructions to project the augmented image on the vehicle mirror, wherein the augmented image is superimposed on a reflected image of the detected object in the mirror.

9. The system of claim 6 , wherein the instructions include further instructions to determine the risk based on the physical attribute of the detected object and a risk classifier.

10. The system of claim 6 , wherein the instructions include further instructions to adjust the motion of the image of the detected object by blinking the image at a frequency, wherein the frequency is based on the determined risk.

11. A system, comprising:
means for detecting an object exterior to a vehicle;
means for outputting an augmented image of the detected object to a vehicle display device, wherein at least one of dimensions and a motion of the augmented image is adjusted based on an environmental condition and physical attribute of the detected object including at least one of a speed, an acceleration, a location, and a direction of the detected object;
means for determining a risk of collision posed by the detected object based on a speed, an acceleration, a time to collision, a distance of the object, and a plurality of risk classifiers, wherein the risk classifiers include graphs specifying respective distance, speed, and acceleration risks;
means for determining a compensated risk of collision based on a plurality of multiplier factors and the determined risk, each of the multiplier factors corresponding to a different environmental condition in a plurality of environmental conditions; and
means for adjusting the dimensions of the image of the detected object based on the compensated risk of collision.
