Publication number: 20220178705Abstract: Systems and methods described herein are provided for determining a platoon configuration for a group of vehicles, determining a set of routes connecting two locations, determining for each route segment the platoon configurations supported and the availability of roadside units on the route segment, and selecting a route from the set of routes connecting the two locations. A route may be selected based on the availability of a roadside unit (RSU) to request an extended time period for a green light to enable a length of the platoon to traverse through an intersection prior to the time period ending. Systems and methods described herein may enable a reconfiguration of a platoon to meet a platoon size restriction for a segment of the selected route.Type: ApplicationFiled: March 1, 2022Publication date: June 9, 2022Inventors: Mikko Tarkiainen, Matti Kutila, Ari Virtanen, Pertti Peussa

Patent number: 10921810Abstract: Systems and methods described herein determine an optimal lane trajectory and route for an autonomous vehicle under changing road conditions and forecast autonomous car performance along a route. A road's profile is analyzed to determine a safe lateral lane position. In ice or snow, a vehicle may follow ruts made by previous vehicles, even if following such ruts does not place a vehicle in a lane's center. In warmer weather, a vehicle may drive outside the ruts to avoid risks of aquaplaning. Dynamic road conditions and AV support along a route are used to maximize AV use and to forecast AV performance. A vehicle control system calculates sensor limitations and uses these sensor limitations when calculating which route to select.Type: GrantFiled: July 26, 2017Date of Patent: February 16, 2021Assignee: PCMS Holdings, Inc.Inventors: Matti Kutila, Mikko Tarkiainen, Pertti Peussa, Ari Virtanen, Samian Kaur

Patent number: 10730512Abstract: Systems and methods related to dynamic map layers for autonomous or semi-autonomous vehicles and allowing real-time (e.g. latency of less than one second) updates utilizing a plurality of available surrounding sensors (e.g., collaborative sensors), including roadside sensors and sensors of other nearby vehicles. When a vehicle detects an obstruction to a field of view of a sensor, the vehicle may request sensor data from other vehicles to fill the gap in sensor data of the vehicle. This allows the vehicle driver or vehicle illumination system to be focused on the obstructed area.Type: GrantFiled: April 27, 2017Date of Patent: August 4, 2020Assignee: PCMS HOLDINGS, INC.Inventors: Matti Kutila, Mikko Tarkiainen, Pertti Peussa, Ari Virtanen

Patent number: 9873590Abstract: The invention relates to a method and apparatus. In the method a target area is divided to a plurality of cells. A plurality of movement paths of mobile nodes are determined, each movement path comprising an origin cell and a target cell, the origin cell and the target cell being determined using a magnetic map of the target area. The durations of the plurality of movement paths are determined for an elevator user. A route topology data structure is formed using the plurality of movement paths and the durations of the plurality of movement paths, the data structure comprising for a plurality of cells an estimated time to reach an elevator location. An elevator call in a request cell is determined by a requesting mobile node.Type: GrantFiled: July 21, 2015Date of Patent: January 23, 2018Assignee: Kone CorporationInventors: Jukka Salmikuukka, Ari Virtanen, Kenneth Kronkvist
