Publication number: 20240134043Abstract: The parking assist apparatus includes a sensor that detects an object by receiving a reflected wave reflected by the object by a transmitted wave, and a controller that executes parking assist control for parking the vehicle in a parking space set based on a detection result of the sensor. The controller provides a predetermined margin to a size of a peripheral object, which is an object detected by the sensor and exists around the parking space, in a provisional direction in which the parking space is narrowed. The controller executes parking assist control using a size of the peripheral object to which the margin is provided. When the size of the peripheral object newly detected by the sensor becomes larger than the size to which the margin is provided, the controller executes parking assist control using the size of the peripheral object newly detected by the sensor.Type: ApplicationFiled: September 13, 2023Publication date: April 25, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Motonari OBAYASHI, Takuya NAKAGAWA, Yoshiki HAYAKAWA

Publication number: 20230070221Abstract: In an obstacle detection apparatus, the captured image of a vicinity of a vehicle from an imaging apparatus is acquired. A three-dimensional estimation image showing a three-dimensional position of a feature point in the captured image is generated, and a three-dimensional position of an object is estimated. An attribute image in which an object in the captured image is classified into one or more classes that include at least a road-surface class is generated. The three-dimensional estimation image and the attribute image are fused, the feature points and the classes are associated, and road-surface points associated with the road-surface class are extracted. Based on the road-surface points, a road-surface height in the vicinity of the vehicle is estimated. Based on the estimated road-surface height, the three-dimensional position of the object is corrected. Based on the three-dimensional position of the object, an obstacle in the vicinity of the vehicle is detected.Type: ApplicationFiled: September 7, 2022Publication date: March 9, 2023Inventors: Shusaku SHIGEMURA, Yuta SAKAKIBARA, Takuya NAKAGAWA, Motonari OBAYASHI
