The research of the applicant shows that: when the existing vehicle-mounted weighing is carried out on the inclined vehicle body, the indication number of the weighing sensor is generally directly used as the pressure received by the weighing sensor, so that the inclination compensation is carried out. However, this does not take into account that tilting friction forces will cause the strain portion of the load cell to be strained, resulting in an indication of the load cell that is not entirely caused by pressure. Therefore, the prior art is not accurate enough to carry out vehicle-mounted weighing on an inclined vehicle body.
