  "textContent": "This application discloses a vehicle drivable area detection method, an autonomous driving assistance system, and an autonomous driving vehicle. The method includes: processing, by using a neural network, image data obtained by a camera apparatus, to obtain a first probability distribution of an obstacle; obtaining a second probability distribution of the obstacle based on a time of flight and an echo width of a radar echo signal; and obtaining, based on the first probability distribution of the obstacle and the second probability distribution of the obstacle, a drivable area of a vehicle represented by a probability, where the probability is a probability that the vehicle cannot drive through the area. The autonomous driving assistance system includes a camera apparatus, at least one radar, and a processor. The system is configured with the technical solutions that can implement the method. The autonomous driving vehicle includes the foregoing autonomous driving assistance system. In the method in this application, two sensors: a camera apparatus and a radar are integrated, distribution information about the obstacle obtained by the two sensors is fused, and the drivable area of the vehicle obtained after fusion is represented in a form of a probability. Therefore, information about the obstacle around the vehicle can be comprehensively obtained, so that a detection blind spot caused by a blind spot of the camera apparatus or a detection range of the radar is avoided.",
