摘要： An object proximity sensor comprising a proximity sensing circuit portion (208), a power supply (214) for supplying power to the proximity sensing circuit portion (208) and an external housing. The object proximity sensor further comprises an orientation sensing arrangement (202). The orientation sensing arrangement (202) is arranged to prevent or limit supply of power from the power supply (214) to the proximity sensing circuit portion (208) when the housing is in an initial orientation,and to permit or increase supply of power from the power supply (208) to the proximity sensing circuit portion if the housing is inverted into a subsequent orientation.

摘要： A charging station (1) for controlling charging of a vehicle comprises: a charging device (2) and one or more sensors (4, 10) arranged to detect presence of a vehicle (16) in a predetermined area in a vicinity of the charging device (2). The charging station (1) is arranged to acquire information for identifying the vehicle (16), communicate the identifying information to an authorisation server (24), receive an authorisation status from the authorisation server (24) and enable electrical power to be supplied to the vehicle (16) by the charging device (2) if the authorisation status is positive. The charging station (1) may transmit a first set of polling signals at a first rate; transmit a second set of polling signals at a second, lower rate upon detecting the presence of a vehicle (16); and acquire the information for identifying the vehicle from a signal received in response to at least one of the polling signals.

摘要： A vehicle sensor (100) suitable for installation in the ground. The vehicle sensor (100) includes a housing unit comprising a rigid lower part (104) and an upper part (102). The upper part (102) has a resilient, convex upper surface (114). The upper part (102) is sealed onto the lower part (104) using a clamping band (106).

摘要： Method and system for zone based detection of vehicles passing into and out from a geographical zone using polygons to define the border of said zone, wherein a first polygon (32) defines a virtual border against which vehicles passing into the zone is compared by use of a GNSS system (10) comprising an OBU in every vehicle to be surveyed by the method. A second polygon (31) larger than the first polygon (32) and completely enveloping said first polygon is defined as a virtual border against which objects passing out from the zone is compared by use of the GNSS system.

摘要： A Particle filter, also known as Sequential Monte Carlo Method, is 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 may be analysed to assess if the event actually took place or not. The use of Particle filter overcomes limitations occurring while employing more traditional Kalman filter based methods.

摘要： Method and system for detecting passages by vehicle at a virtual gantry controlled by a GNSS system comprising an OBU in every vehicle to be surveyed by the system, said OBU receiving signals from satellites to consistently and frequently estimate positions for the vehicle, the method comprising the steps of: defining a virtual gantry in terms of a number of ordered passage lines (PL) across a road; determining intersection points (i) from the intersection between the GNSS trace and the passage line(PL); calculating a value representing probability of a true passage at that passage line (PL); for each vehicle for which intersection points (i) have been determined for at least two different passage lines (PL), calculating a total probability value based on the individually calculated probability values; concluding of a true passage by the vehicle in question only if the total probability value is exceeding a predefined minimum value.
