To enable other vehicles, pedestrians or the like to recognize a vehicle located in a dead angle area.
A device 11 for performing laser beam irradiation decision, collision decision and collision avoidance control includes a trajectory prediction section for predicting the running trajectory of the vehicle of interest, and a projection direction modification section. The trajectory prediction section predicts the vehicle running trajectory, based on a vehicle steering angle detected by a steering angle sensor, a vehicle yaw rate detected by a gyro sensor, and a vehicle velocity detected by a vehicle velocity sensor. The irradiation direction modification section modifies the direction of the laser beam irradiation so that a laser beam irradiation position Q irradiated from a laser projector 13 of the vehicle lies on a predetermined position of the vehicle running trajectory predicted by the trajectory prediction section.
