US 2025/0083649 A1 · AUTOMATIC VEHICLE BRAKING CONTROL SYSTEMS

Abstract

A method of automated vehicle braking control includes detecting a first object threat in a reverse travel path of a vehicle, monitoring a distance of the vehicle from the first object threat with respect to a time to collision threshold, and in response to a determination that the vehicle is crossing the time to collision threshold, initiating a first rear virtual bumper event by automatically applying brakes of the vehicle. The method includes storing a location of the first object threat, defining a boundary region surrounding the location of the first object threat, detecting a second object threat in the reverse travel path, comparing a location of the second object threat with the boundary region, and inhibiting automatic application of the brakes in response to a determination that the location of the second object threat is within the boundary region, to avoid a second rear virtual bumper event.

Dependent claims

A method of automated vehicle braking control, the method comprising:

detecting, by at least one vehicle sensor, a first object threat in a reverse travel path of a vehicle;
monitoring a distance of the vehicle from the first object threat with respect to a time to collision threshold;
in response to a determination that the vehicle is crossing the time to collision threshold, initiating a first rear virtual bumper event by automatically applying brakes of the vehicle;
storing a location of the first object threat;
defining a boundary region surrounding the location of the first object threat;
subsequent to the first rear braking event, detecting a second object threat in the reverse travel path, by the at least one vehicle sensor;
comparing a location of the second object threat with the boundary region;
and
inhibiting automatic application of the brakes in response to a determination that the location of the second object threat is within the boundary region, to avoid a second rear virtual bumper event.

6 more elements

An automated vehicle braking control system comprising:

a brake control module configured to automatically apply brakes of a vehicle in response to a rear virtual bumper event signal;
at least one vehicle sensor configured to detect object threats in a reverse travel path of the vehicle;
and
a vehicle control module in communication with the braking control module and the at least one vehicle sensor, the vehicle control module configured to:
detect, via the at least one vehicle sensor, a first object threat in the reverse travel path of a vehicle;
monitor a distance of the vehicle from the first object threat with respect to a time to collision threshold;
in response to a determination that the vehicle is crossing the time to collision threshold, transmit a signal indicating a first rear virtual bumper event to the brake control module to automatically apply brakes of the vehicle;
store a location of the first object threat;
define a boundary region surrounding the location of the first object threat;
subsequent to the first rear virtual bumper event, detect a second object threat in the reverse travel path, via the at least one vehicle sensor;
compare a location of the second object threat with the boundary region;
and
inhibit automatic application of the brakes in response to a determination that the location of the second object threat is within the boundary region, to avoid a second rear virtual bumper event.
