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.

17. 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 collision parameter based on an indicator of a relative acceleration between the vehicle and the object; compare the at least one collision parameter with a predetermined threshold; and cause a response in the system if the comparison between the at least one collision parameter and the predetermined threshold indicates of a possible collision between the vehicle and the object. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)

26. 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 collision parameter based on an indicator of a relative acceleration between the vehicle and an object; compare the at least one collision parameter with a predetermined threshold; and cause a response in the system if the comparison between the at least one collision parameter and the predetermined threshold indicates of a possible collision between the vehicle and the object. - View Dependent Claims (27, 28, 29)

30. 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 from an image capture device a plurality of images acquired of the object; determine, based on the plurality of images of the object, a possible collision between the vehicle and the object, when there is non-zero relative acceleration between the object and the vehicle; and cause a collision avoidance response at a time T different from a time T′
at which an instantaneous relative velocity between the vehicle and the object and a distance between the vehicle and the object together correspond to a collision warning threshold.- View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39)
