Patent number: 11919567Abstract: An automatic steering control apparatus includes a lane line detector, a shape data detector, a traveling processor, and a steering angle processor. The lane line detector is configured to detect right and left lane lines. The shape data detector is configured to detect shape data. The traveling processor is configured to, in a case where both the lane lines are detected, execute a first lane-line control that is an automatic steering control to be executed on the basis of both the lane lines, and configured to, in a case where only one of the lane lines is detected as a detected lane line, execute a determining process that compares data on the detected lane line and the shape data and that determines whether to execute a second lane-line control that is the automatic steering control to be executed on the basis of only the one of the lane lines.Type: GrantFiled: October 4, 2021Date of Patent: March 5, 2024Assignee: SUBARU CORPORATIONInventors: Yuki Takehara, Hidenori Yakuwa, Keisuke Motegi

Patent number: 11858510Abstract: A vehicle drive assist apparatus includes an external environment recognizer, a traveling environment recognizer, and a processor. The traveling environment recognizer recognizes travel lane sides of dividing lines defining a travel lane as two approximate lines each in a linear form based on the image data on a traveling environment acquired by the external environment recognizer. When a static three-dimensional object has been continuously detected on or near one of dividing lines based on the image data, the processor sets a virtual approximate line by correcting the lateral position of the approximate line of the one of the dividing lines in a direction apart from the static three-dimensional object toward the middle of the travel lane by a predetermined correction amount, and sets a target travel course in the middle between the virtual approximate line and the approximate line of the other of the dividing lines.Type: GrantFiled: October 4, 2021Date of Patent: January 2, 2024Assignee: SUBARU CORPORATIONInventors: Keisuke Motegi, Masatoshi Minakawa

Publication number: 20230086053Abstract: A driving assist apparatus for a vehicle includes a front-side-environment recognition camera, a front-side-environment recognition sensor, and a control device. The front-side-environment recognition camera is configured to recognize a driving environment ahead of the vehicle. The front-side-environment recognition sensor is configured to recognize the driving environment ahead of the vehicle. In a case where image recognition of the front-side-environment recognition camera for a leading vehicle for adaptive cruise control has deteriorated during execution of the adaptive cruise control, the control device is configured to continue executing the adaptive cruise control based on a distance from the vehicle to the leading vehicle obtained by the front-side-environment recognition sensor.Type: ApplicationFiled: August 25, 2022Publication date: March 23, 2023Inventors: Ryuya AZUMA, Hikaru YOSHIKAWA, Masahito SEKINE, Yuta SATO, Keisuke MOTEGI

Publication number: 20230090300Abstract: A driving assist apparatus for a vehicle includes a camera device, a radar device, an image recognition unit, and a driving control unit. The camera device obtains images around the vehicle. The radar device obtains three-dimensional object data around the vehicle. The image recognition unit recognizes a marking line and a road edge and calculates a distance therebetween from a distance between the vehicle and the marking line and a distance between the vehicle and the road edge. The driving control unit controls driving of the vehicle based on the marking line and the road edge. When the image recognition unit fails to recognize the marking line, it sets an estimated marking line, based on the distance between the road edge and the marking line and the distance between the vehicle and the road edge, and the driving control unit controls the driving of the vehicle using the estimated marking line.Type: ApplicationFiled: August 25, 2022Publication date: March 23, 2023Inventors: Keisuke MOTEGI, Hikaru YOSHIKAWA, Masahito SEKINE, Yuta SATO, Ryuya AZUMA
