Abstract:
1. A driving assistance device that can implement emergency avoidance assistance which is assistance for urgently avoiding a collision between a host vehicle and an obstacle and prediction assistance which is assistance for avoiding a future collision between a host vehicle and an obstacle in advance, and implements the assistance by selecting any of the emergency avoidance assistance and the prediction assistance, the driving assistance device comprising: necessity determination means for determining whether or not the emergency avoidance assistance is necessary; collision prediction means for predicting a future traveling range of the host vehicle and a future moving range of the obstacle, and predicting a possibility of the future collision based on the predicted traveling range and the moving range, and then determining whether or not the prediction assistance is necessary, in a case where the necessity determination means determines that the emergency avoidance assistance is not necessary; and implementation means for implementing the emergency avoidance assistance in a case where the necessity determination means determines that the emergency avoidance assistance is necessary, and implementing the prediction assistance in a case where the collision prediction means determines that the prediction assistance is necessary, wherein the necessity determination means determines the possibility of the collision between the host vehicle and the obstacle in a case where the current state of the host vehicle and the obstacle will be continued, and determines that the emergency avoidance assistance is necessary in a case where it is determined that there is a possibility of the collision.
