A driving support system, comprising: a blind area recognition unit capable of recognizing a blind area (DE1, DE2) for a driver in a travel direction of a host vehicle; a target speed determining unit capable of determining a target speed of the host vehicle on the basis of the blind area recognized by the blind area recognition unit; and a driving support unit capable of supporting driving of the host vehicle on the basis of the target speed determined by the target speed determining unit, characterized in that the target speed determining unit is capable of determining the target speed on the basis of a safe-condition confirmation end point that is set to a first predetermined position in the travel direction of the host vehicle, and on the basis of a safe-condition confirmation start point that is set to a second predetermined position before the safe-condition confirmation end point in the travel direction of the host vehicle, the safe-condition confirmation end point is a point subsequent to which the host vehicle passes through a section in which it is assumed that the host vehicle SM passes through in advance of a moving object that appears from the blind area (DE1, DE2) without a collision with the moving object, the safe-condition confirmation start point is a point at which it is ensured a set line-of-sight angle with respect to the blind area, and the safe-condition confirmation start point and the safe-condition confirmation end point define a safe-condition confirmation section in which the driving support unit is configured to bring an actual speed of the host vehicle to the target speed (Vt). a blind area recognition unit capable of recognizing a blind area (DE1, DE2) for a driver in a travel direction of a host vehicle; a target speed determining unit capable of determining a target speed of the host vehicle on the basis of the blind area recognized by the blind area recognition unit; and a driving support unit capable of supporting driving of the host vehicle on the basis of the target speed determined by the target speed determining unit, characterized in that the target speed determining unit is capable of determining the target speed on the basis of a safe-condition confirmation end point that is set to a first predetermined position in the travel direction of the host vehicle, and on the basis of a safe-condition confirmation start point that is set to a second predetermined position before the safe-condition confirmation end point in the travel direction of the host vehicle, the safe-condition confirmation end point is a point subsequent to which the host vehicle passes through a section in which it is assumed that the host vehicle SM passes through in advance of a moving object that appears from the blind area (DE1, DE2) without a collision with the moving object, the safe-condition confirmation start point is a point at which it is ensured a set line-of-sight angle with respect to the blind area, and the safe-condition confirmation start point and the safe-condition confirmation end point define a safe-condition confirmation section in which the driving support unit is configured to bring an actual speed of the host vehicle to the target speed (Vt).
