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; identify a position of the object in at least two images of the plurality of ages; determine, based on the plurality of images, a value indicative of a time-to-collision (TTC) that is responsive to a relative acceleration between the vehicle and the object; determine if the vehicle and the object are on a collision course based on the position of the object in the at least two images and the value indicative of the TTC; and cause a response in the system if he vehicle and the object are determined to be on a collision course. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A vehicle, comprising:
-
a body; an image capture configured to acquire images from an environment of the vehicle; at least one processing device configured to; receive a plurality of images from the image capture device; identify a position of the object in at least two images of the plurality of images; determine, based on the plurality of images, a value indicative of a time-to-collision (TTC) that is responsive to a relative acceleration between the vehicle and the object; determine if the vehicle and the object are on a collision course based on the position of the object in the at least two images and the value indicative of the TTC; and cause a response by the vehicle if the vehicle and the object are determined to be on a collision course.

34. A method for providing an indication of a possible collision between a vehicle and an object, the method comprising:
-
receiving a plurality of images from an image capture device; identifying a position of the object in at least two images of the plurality of images; determining, based on the plurality of images, a value indicative of a time-to-collision (TTC) that is responsive to a relative acceleration between the vehicle and the object; determining if the vehicle and the object are on a collision course based on the position of the object in the at least two images and the value indicative of the TTC; and causing a response by the vehicle if the vehicle and the object are determined to be on a collision course.
