  • Patent number: 11703374
    Abstract: A charging system includes load meters mounted in a vehicle, the load meters each measuring a load exerted on an axle or a wheel and deciding a measurement result and an onboard unit that acquires the measurement results of the load meters and is capable of communicating weight information on the weight of the vehicle based on the measurement results to a roadside machine.
    Type: Grant
    Filed: February 10, 2017
    Date of Patent: July 18, 2023
    Assignee: MITSUBISHI HEAVY INDUSTRIES MACHINERY SYSTEMS, LTD.
    Inventors: Hiroyuki Nakayama, Kenta Nakao, Takaaki Sunagawa, Koichi Kanehara
  • Patent number: 11410470
    Abstract: Provided is a charging system including: an axle load meter disposed on a lane and configured to measure an axle load of each of a plurality of axles of a vehicle traveling on the axle load meter; an acceleration information acquisition unit configured to acquire, from the vehicle, vertical-direction acceleration information associated with each of the axles; a correction calculation unit configured to calculate a corrected axle load for each of the axles by correcting, based on the vertical-direction acceleration information, a measurement result for each of the axles obtained by the axle load meter; and a toll determination unit configured to determine a toll for the vehicle based on the corrected axle load for each of the axles.
