A braking system (10) suitable for use on an automated vehicle includes a ranging-sensor (14), a braking-actuator (28), and a controller (26). The ranging-sensor (14) detects reflections (16) indicative of objects (18) present in a field-of-view (20) proximate to a host-vehicle (12). The braking-actuator (28) controls movement (30) of the host-vehicle (12). The controller (26) is in communication with the ranging-sensor (14) and the braking-actuator (28). The controller (26) determines a region-of-interest (34) within the field-of-view (20) and defines an occupancy-grid (36) that segregates the field-of-view (20) into an array of grid-cells (38). The controller (26) further determines a repeatability-of-detection (40) of each of the grid-cells (38) based on reflections (16) detected by the ranging-sensor (14). The controller (26) further determines that a rigid-object is present in the field-of-view (20) when each of a string of the grid-cells (38) are characterized by the repeatability-of-detection (40) greater than a repeatability-threshold (46). The controller (26) activates the braking-actuator (28) when the string intersects the region-of-interest (34).
