Abstract
A vehicular peripheral surveillance device includes an obstacle recognition sensor which monitors an obstacle around a host vehicle, a lane recognition sensor and a vehicle state quantity sensor which detect the traveling state of the host vehicle, and a risk computing unit which predicts the movement of the obstacle using information acquired by the obstacle recognition sensor, and computes a risk of the obstacle to the host vehicle on the basis of the predicted movement of the obstacle. The risk computing unit changes the prediction range of the movement of the obstacle on the basis of the traveling state of the host vehicle detected by the lane recognition sensor and the vehicle state quantity sensor. Therefore, the situation of the host vehicle is predicted taking into consideration the movement of the obstacle, thereby realizing computation with high precision while reducing a computation load.
