Abstract
A method of estimating a time to collision (TTC) of a vehicle with an object comprising: acquiring a plurality of images of the object; and determining a TTC from the images that is responsive to a relative velocity and relative acceleration between the vehicle and the object.
Claims23
-16. (canceled)
A system for providing an indication of a possible collision between a vehicle and an object, the system comprising:
- at least one processing device configured to:
- receive a plurality of images from an image capture device;
- use the plurality of images to determine at least one value indicative of a Time To Collision (TTC) based on an indicator of a relative acceleration between the vehicle and the object;
- compare the at least one value indicative of the TTC with a threshold;
- and
- cause a response in the system if the comparison between the at least one value indicative of the TTC and the threshold indicates a possible collision between the vehicle and the object.
3 more elements
A vehicle, comprising:
- a body;
- an image capture device having at least one field of view relative to an exterior of the body, the image capture device configured to acquire image data at time intervals to provide a plurality of images;
- at least one processing device configured to:
- use the plurality of images to determine at least one value indicative of a Time To Collision (TTC) based on an indicator of a relative acceleration between the vehicle and an object;
- compare the at least one value indicative of the TTC with a threshold;
- and
- cause a vehicular response if the comparison between the at least one value indicative of the TTC and the threshold is indicative of a possible collision between the vehicle and the object.

A method for providing indication of a possible collision between a vehicle and an object, the method comprising:
- acquiring, using an image capture device, image data at time intervals to provide a plurality of images;
- using the plurality of images to determine at least one value indicative of a Time To Collision (TTC) based on an indicator of a relative acceleration between the vehicle and the object;
- comparing the at least one value indicative of the TTC with a threshold;
- and
- causing a response if the comparison between the at least one value indicative of the TTC and the threshold indicates a possible collision between the vehicle and the object.
