1. An onboard system comprising:
a plurality of 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;
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; and
a static sensor that detects that the vehicle is static and transmits a static detection signal to the onboard unit,
wherein the onboard unit adds identification information on the axles to the weight information and transmits the weight information to the roadside machine,
wherein, in response to the static detection signal, the onboard unit transmits a request signal to each of the load meters, and
wherein, in response to the request signal, each of the load meters decides the measurement result of the corresponding axle.
