Abstract: A method of determining obstacles determines if a detected object detected outside a subject vehicle is an obstacle for the subject vehicle on the basis of a predetermined determination criterion. In this method, a determination is made whether or not the detected object detected outside the subject vehicle is a driver or passenger of the subject vehicle. When the detected object is not the driver or passenger, a determination is made whether or not the detected object is an obstacle for the subject vehicle on the basis of a first determination criterion. When the detected object is the driver or passenger, a determination is made whether or not the detected object is an obstacle for the subject vehicle on the basis of a second determination criterion with which the detected object is less likely to be determined as an obstacle for the subject vehicle than with the first determination criterion.
