Multi-threshold reaction zone for autonomous vehicle navigation
First Claim
1. A driver assist navigation system for a primary vehicle, the system comprising:
- at least one camera configured to acquire a plurality of images of an area in a vicinity of the primary vehicle;
a data interface; and
at least one processing device configured to;
receive the plurality of images via the data interface;
identify a target object within the plurality of images;
monitor, via the plurality of images, a motion of the target object and a distance between the primary vehicle and the target object;
determine an indicator of an intercept time between the primary vehicle and the target object based on the monitored motion and the distance between the primary vehicle and the target object; and
cause a response in the primary vehicle based on a comparison of the indicator of the intercept time to a predetermined intercept threshold, wherein the response is based on an average motion or an actual motion of the target object when the indicator of the intercept time is greater than or equal to the predetermined intercept threshold, and the response includes an emergency avoidance action when the indicator of the intercept time is below the predetermined intercept threshold.

Abstract
Systems and methods use cameras to provide autonomous navigation features. In one implementation, a driver assist navigation system for a primary vehicle may include at least one image capture device configured to acquire a plurality of images of an area in a vicinity of the primary vehicle; a data interface; and at least one processing device. The at least processing device may be configured to: receive the plurality of images via the data interface; identify a target object within the plurality of images; monitor, via the plurality of images, a motion of the target object and a distance between the primary vehicle and the target object; determine an indicator of an intercept time between the primary vehicle and the target object based on the monitored motion and the distance between the primary vehicle and the target object; and cause a response in the primary vehicle based on a comparison of the intercept time to a plurality of predetermined intercept thresholds.

21. A method for navigating a primary vehicle, the method comprising:
-
acquiring, via at least one camera, a plurality of images of an area in a vicinity of the primary vehicle; identifying a target object within the plurality of images; monitoring, based on the plurality of images, a motion of the target object and a distance between the primary vehicle and the target object; determining an indicator of an intercept time between the primary vehicle and the target object based on the monitored motion and the distance between the primary vehicle and the target object; and causing a response in the primary vehicle based on a comparison of the indicator of the intercept time to a predetermined intercept threshold, wherein the response is based on an average motion or an actual motion of the target object when the indicator of the intercept time is greater than or equal to the predetermined intercept threshold, and the response includes an emergency avoidance action when the indicator of the intercept time is below the predetermined intercept threshold. - View Dependent Claims (22, 23, 24, 25)
