SYSTEMS AND METHODS FOR BRAKING A VEHICLE BASED ON A DETECTED OBJECT
First Claim
1. An object detecting and braking system for a vehicle, comprising:
- at least one image capture device configured to acquire a plurality of images of an area including an object in front of the vehicle;
a data interface; and
at least one processing device programmed to;
receive the plurality of images via the data interface;
perform a first image analysis based on at least a first image and a second image to determine a first estimated time-to-collision of the vehicle with the object;
perform a second image analysis based on at least a third image and a fourth image to determine a second estimated time-to-collision of the vehicle with the object;
calculate a difference between the first estimated time-to-collision and the second estimated time-to-collision;
determine that the difference does not exceed a predetermined threshold; and
cause the vehicle to brake based on the determination that the difference does not exceed the predetermined threshold.

Abstract
Systems and methods are provided for detecting an object and causing a vehicle to brake based on the detection. In one implementation, an object detecting and braking system for a vehicle includes at least one image capture device configured to acquire a plurality of images of an area including an object in front of the vehicle. The system includes at least one processing device programmed to perform a first image analysis to determine a first estimated time-to-collision of the vehicle with the object, and to perform a second image analysis to determine a second estimated time-to-collision of the vehicle with the object. The processing device is also programmed to calculate a difference between the first estimated time-to-collision and the second estimated time-to-collision, to determine that the difference does not exceed a predetermined threshold, and to cause the vehicle to brake based on the determination that the difference does not exceed the predetermined threshold.

21. A method for assessing an overall system failure rate associated with a braking decisioning system for a vehicle, comprising:
-
determining, using a processing device, a first failure rate associated with a textural analysis based sub-system, wherein the textural analysis based sub-system is configured to make a decision to brake based on a change in texture between at least two images of an area in front of a vehicle; determining, using the processing device, a second failure rate associated with a structural analysis based sub-system, wherein the structural analysis based sub-system is configured to make a decision to brake based on optical flow information derived from at least two images of the area in front of the vehicle; and determining, using the processing device, the overall system failure rate based on the first future rate and the second failure rate. - View Dependent Claims (22)
