A vehicle drive-assist apparatus includes: a first front-environment recognizer recognizing, with a vehicle-mounted autonomous sensor, a front environment; a second front-environment recognizer recognizing the front environment on the basis of information received from an external device via external communication; a first brake controller determining, when a preceding vehicle is recognized by the first front-environment recognizer, a target position on the basis of the preceding vehicle, and executing a first brake control based on the target position; and a second brake controller determining, when the preceding vehicle is recognized only by the second front-environment recognizer, the target position on the basis of the preceding vehicle, and determining a corrected target position by correcting the target position, and executing a second brake control based on the corrected target position in advance of the first brake control. The corrected target position is farther from the own vehicle than the target position is.
