Patent number: 10504363Abstract: A vehicle detection and classification system which comprises a plurality of proximity sensors is distributed in a fixed spatial array relative to a road such that a distance of each sensor to the nearest adjacent sensor is less than a minimum horizontal dimension of a vehicle to be detected. The array has a maximum dimension greater than the minimum horizontal dimension of a vehicle to be detected. Each of the sensors is configured to determine presence or absence of a vehicle and to communicate data regarding said presence determination to a data processing system, wherein the data processing system is configured to use data from a plurality of the sensors to detect and classify a vehicle on the road based on at least one dimension of the vehicle.Type: GrantFiled: September 6, 2018Date of Patent: December 10, 2019Assignee: Q-Free ASAInventors: Brage Blekken, Anders Ivar Hagen, Ola Martin Lykkja

Patent number: 9886849Abstract: A particle filter, also known as Sequential Monte Carlo Method, used to estimate vehicle position based on GNSS pseudo range measurements and other sensors. The particle filter creates an ensemble of particles and road user charging (road tolling) can be performed on each particle. The resulting distribution of assessed vehicle passages is analyzed to assess if the event actually took place or not. The use of particle filter overcomes limitations occurring while employing traditional Kalman filter based methods.Type: GrantFiled: June 1, 2015Date of Patent: February 6, 2018Assignee: Q-Free ASAInventors: Ola Martin Lykkja, Geir Olve Storvik, Jon Glenn Gjevestad, Anders Løland
