Publication number: 20240010233Abstract: The present technology pertains to determining whether traffic signal cameras of an AV are miscalibrated. One technique for determining if a given traffic signal camera is miscalibrated includes obtaining an image from a traffic signal camera, marking the location of a traffic signal in the image with a bounding box, and determining if the light sources of the traffic signal are within the bounding box. If not, an alternate reason check is performed to determine whether an alternate reason exists for why the light source of the traffic signal is not within the bounding box. If no such reason exists, then the traffic signal camera may be miscalibrated. An additional calibration check may be performed using images from two traffic signal cameras of the AV each having four common light sources, and performing a homographic computation using the location of the light sources in the images.Type: ApplicationFiled: July 7, 2022Publication date: January 11, 2024Inventors: Himil Narayan Sheth, Zhizhong Yan

Publication number: 20240010270Abstract: A method is for operating a vehicle including a steering system having a steering handle and at least one wheel steering angle actuator operatively connected to the steering handle for changing a wheel steering angle of at least one vehicle wheel. The method includes, in a normal operating state, controlling at least one steering functionality depending on an operating parameter correlated with a current vehicle speed, and, in an operational fault state in which an availability of the operating parameter is restricted and/or a failure of the operating parameter is determined, replacing the operating parameter by a replacement parameter correlated to a replacement speed. The method also includes performing a situationally adjusted transition from the operating parameter to the replacement parameter.Type: ApplicationFiled: July 10, 2023Publication date: January 11, 2024Inventors: Nicolas Boos, Thomas Werner

Publication number: 20240010273Abstract: A bulldozer causes left and right steering clutches to engage and left and right steering brakes to release when an operating amount of a steering lever is greater than a first predetermined amount and less than a second predetermined amount, and drives a turning motor so that the rotation speed of an inside output shaft becomes lower than the rotation speed of an outside output shaft as the operating amount of the steering lever increases. A controller causes the engagement rate of an inside steering clutch to decrease and causes an inside steering brake to brake when the operating amount of the steering lever is equal to or greater than the second predetermined amount.Type: ApplicationFiled: November 5, 2021Publication date: January 11, 2024Inventors: Takeshi YOSHIKAWA, Hiroaki TAKESHIMA, Naoya AKIYAMA, Toshikazu OKADA, Kazushi NAKATA, Osamu YATSUDA
