A method for avoiding a collision of a vehicle with an obstacle, using at least one ultrasonic sensor. Reflection points are determined during a movement of the vehicle, the reflection points representing locations at which a signal of an ultrasonic sensor was reflected. The reflection points are combined into contiguous, linearly extending wall sections, a wall section having two ends. Furthermore, it is determined whether an end of a wall section is open or closed. The progression abutting an open end of a wall section is extrapolated, and virtual collision points between the vehicle and the extrapolated progression of the wall sections are ascertained. An initiation of a brake intervention follows if a collision with a virtual collision point is imminent. A driver assistance system including at least one ultrasonic sensor configured to carry out the method, and a vehicle including such a driver assistance system, are also described.
