To improve the visibility of pedestrians and the like in front of a vehicle.
This driving assisting device of a vehicle comprises a plurality of UV radiation means (80, 90) radiating ultraviolet rays in front of the vehicle, vision detection means (30, 50, ST120) detecting a vision of a driver of the vehicle, and control means (50, 60, 70) changing radiation directions of the UV radiation means (80, 90) according to the vision detected by the vision detection means (30, 50, ST120). In this driving assisting device of a vehicle, the ultraviolet rays are radiated to follow the vision of the driver, so that a target in a vision direction can be highlighted. Therefore, visibility of the driver can be improved compared to the case where the radiation direction of the ultraviolet rays is fixed to a preset direction.
