An automated braking system for use on an automated vehicle includes a braking-actuator, a ranging-sensor, a digital-map, and a controller. The braking-actuator controls movement of a host-vehicle. The ranging-sensor detects a distance, a direction, and an elevation of targets in a field-of-view of the ranging-sensor. The field-of-view includes a roadway. The digital-map defines a travel-route of the host-vehicle and specifies a gradient of the roadway. The controller is in communication with the braking-actuator, the ranging-sensor, and the digital-map. The controller determines that a first-collection of the targets above a horizon is an overpass when the gradient indicates that the roadway descends below the overpass. The controller disregards the first-collection of targets associated with the overpass when the gradient is indicated, and activates the braking-actuator when the controller determines that a second-collection of targets from below the horizon are an obstruction on the travel-route beneath the overpass.
