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.
Claims19
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 a plurality of values indicative of a Time-to-Collision (TTC) based on an indicator of a relative velocity between the vehicle and the object;
- determine a rate of change of the plurality of values indicative of the TTC at a selected time;
- and
- based on the determined rate of change, cause a response in the system if a possible collision between the vehicle and the object is anticipated.
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 a plurality of values indicative of a Time-to-Collision (TTC) based on an indicator of a relative velocity between the vehicle and the object;
- determine a rate of change of the plurality of values indicative of the TTC at a selected time;
- and
- based on the determined rate of change, cause a response in the vehicle if a possible collision between the vehicle and the object is anticipated.

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 a plurality of values indicative of a Time To Collision (TTC) based on an indicator of a relative velocity between the vehicle and the object;
- determining a rate of change of the plurality of values indicative of the TTC at a selected time;
- and
- based on the determined rate of change, causing a response in the vehicle if a possible collision between the vehicle and the object is anticipated.
