Patent number: 11740640Abstract: A higher throughput is an increasingly necessary requirement for driverless transport systems with a plurality of driverless transport vehicles. In arrangements with inclined roadways, resuming a movement is problematic in that doing so has hitherto only been possible with a limited arrangement of the roadways and/or with highly dimensioned drives. The novel method provides for moving a driverless transport vehicle on an inclined transport roadway, wherein the steering drives are actuated on the basis of the detected inclination direction in order to move the vehicle such that the transport vehicle is moved transversely to the inclination direction. After a specified minimum speed of the transport vehicle transversely to the inclination direction is reached, the steering drives are adjusted such that the transport vehicle continues to move in the inclination direction.Type: GrantFiled: September 6, 2019Date of Patent: August 29, 2023Assignee: Siemens Logistics GmbHInventor: Carsten Aschpurwis

Patent number: 11703884Abstract: A system for regulating the speed of a vehicle includes defining a first border for a first geographic region. The border has a first speed within the border and a second speed outside of the border. The system includes determining a first velocity of the vehicle including a vehicle speed and direction of the vehicle approaching the border. The difference between the vehicle speed and the second speed is the calculated, as is a distance between the vehicle and the border. If the difference between the vehicle speed and the second speed divided by the distance is greater than a predetermined value, the vehicle is decelerated at a rate so that the vehicle will have a second speed when the vehicle reaches the border.Type: GrantFiled: October 6, 2020Date of Patent: July 18, 2023Assignee: Polaris Industries Inc.Inventors: David G. Hille, Chun Lan, Scott D. Taylor, Joseph B. Bottensek, Jacob D. Scherer, Duane D. Wagner, Jacob J. Minick

Patent number: 11685381Abstract: A method and system for estimating surface roughness of a ground for an off-road vehicle to control steering of a vehicle, an implement, or both, comprises detecting motion data of an off-road vehicle traversing a field or work site during a sampling interval. A first sensor is adapted to detect pitch data of the off-road vehicle for the sampling interval to obtain a pitch acceleration. A second sensor is adapted to detect roll data of the off-road vehicle for the sampling interval to obtain a roll acceleration. An electronic data processor or surface roughness index module determines or estimates a surface roughness index based on the detected motion data, pitch data and roll data for the sampling interval. The surface roughness index can be displayed on the graphical display to a user or operator of the vehicle.Type: GrantFiled: July 8, 2020Date of Patent: June 27, 2023Assignee: Deere & CompanyInventors: Christopher D. Birkland, Tyler D. Schleicher

Patent number: 11650603Abstract: The technology relates to determining general weather conditions affecting the roadway around a vehicle, and how such conditions may impact driving and route planning for the vehicle when operating in an autonomous mode. For instance, the on-board sensor system may detect whether the road is generally icy as opposed to a small ice patch on a specific portion of the road surface. The system may also evaluate specific driving actions taken by the vehicle and/or other nearby vehicles. Based on such information, the vehicle's control system is able to use the resultant information to select an appropriate braking level or braking strategy. As a result, the system can detect and respond to different levels of adverse weather conditions. The on-board computer system may share road condition information with nearby vehicles and with remote assistance, so that it may be employed with broader fleet planning operations.Type: GrantFiled: October 26, 2020Date of Patent: May 16, 2023Assignee: Waymo LLCInventors: David Harrison Silver, Jens-Steffen Ralf Gutmann, Michael James
