Abstract
A system for navigating a host vehicle may receive an image representative of an environment of the host vehicle and determine a planned navigational action for accomplishing a navigational goal of the host vehicle. The system may identify a target vehicle, determine a current speed of the target vehicle, and assume a maximum braking rate capability of the target vehicle. The system may determine a next-state distance between the host vehicle and the target vehicle that would result if the planned navigational action was taken. The system may implement the planned navigational action if the host vehicle may be stopped using a predetermined sub-maximal braking rate within a distance that is less than the determined next-state distance summed together with a target vehicle travel distance determined based on the current speed of the target vehicle and the maximum braking rate capability of the target vehicle.

17. A system for navigating a host vehicle, the system comprising:
at least one processing device programmed to; receive, from an image capture device, at least one image representative of an environment of the host vehicle; determine, based on at least one driving policy, a planned navigational action for accomplishing a navigational goal of the host vehicle; analyze the at least one image to identify a target vehicle in the environment of the host vehicle; determine a next-state distance between the host vehicle and the target vehicle that would result if the planned navigational action was taken; determine a current speed of the host vehicle; determine a current speed of the target vehicle and assume a maximum braking rate capability of the target vehicle based on at least one recognized characteristic of the target vehicle; and implement the planned navigational action if, for the determined current speed of the host vehicle and at a predetermined sub-maximal braking rate that is less than a maximum braking rate capability of the host vehicle, the host vehicle can be stopped within a host vehicle stopping distance that is less than the determined next-state distance summed together with a target vehicle travel distance determined based on the current speed of the target vehicle and the assumed maximum braking rate capability of the target vehicle. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 33, 34, 35, 36, 37, 38, 39, 40)

41. A system for navigating a host vehicle, the system comprising:
at least one processing device programmed to; receive, from an image capture device, at least one image representative of an environment of the host vehicle; determine, based on at least one driving policy, a planned navigational action for accomplishing a navigational goal of the host vehicle; analyze the at least one image to identify a target vehicle in the environment of the host vehicle; determine a next-state distance between the host vehicle and the target vehicle that would result if the planned navigational action was taken; determine a current speed of the host vehicle; determine a current speed of the target vehicle and assume a maximum braking rate capability of the target vehicle based on at least one recognized characteristic of the target vehicle; and implement the planned navigational action if, for the determined current speed of the host vehicle and for a predetermined braking rate profile, the host vehicle can be stopped within a host vehicle stopping distance that is less than the determined next-state distance summed together with a target vehicle travel distance determined based on the current speed of the target vehicle and the assumed maximum braking rate capability of the target vehicle, wherein the predetermined braking rate profile progressively increases from a sub-maximal braking rate to a maximal braking rate for the host vehicle. - View Dependent Claims (42, 43)

44. A system for braking a host vehicle, the system comprising:
at least one processing device programmed to; receive, from at least one sensor, an output representative of an environment of the host vehicle; detect, based on the output, a target vehicle in the environment of the host vehicle; determine a current speed of the host vehicle and a current distance between the host vehicle and the target vehicle; determine, based at least upon the current speed of the host vehicle and the current distance between the host vehicle and the target vehicle, whether a braking condition exists; and if a braking condition is determined to exist, cause application of a braking device associated with the host vehicle according to a predetermined braking profile including a segment beginning at a sub-maximal braking rate for the host vehicle and progressively increasing up to a maximum braking rate of the host vehicle. - View Dependent Claims (45, 46, 47)
