The invention discloses a self-adaptive vehicle-mounted weighing method for vehicle body inclination, which can be realized by appropriately improving technical details by taking the contents of the text as reference by a person skilled in the art. It is expressly intended that all such similar substitutes and modifications which would be obvious to one skilled in the art are deemed to be included in the invention. While the methods and applications of this invention have been described in terms of preferred embodiments, it will be apparent to those of ordinary skill in the art that variations and modifications in the methods and applications described herein, as well as other suitable variations and combinations, may be made to implement and use the techniques of this invention without departing from the spirit and scope of the invention.
The applicant researches and discovers that: when the current carries out on-vehicle weighing to the tilting vehicle body, generally can be directly as the pressure that weighing sensor received to weighing sensor's registration to carry out the slope and mend. However, this does not take into account that the tilting friction can cause the strain section of the load cell to twist, resulting in a load cell reading that is not entirely due to pressure. Therefore, the prior art is not accurate enough to carry out on-vehicle weighing to the tilting vehicle body.
Therefore, an embodiment of the present invention provides a vehicle body inclination adaptive vehicle-mounted weighing method, as shown in fig. 1, the method includes:

In a specific embodiment, a tire pressure gauge is used to perform tire pressure detection on each tire to obtain a first tire pressure.
Optionally, before responding to the cargo being fully loaded on the vehicle, the method further comprises:
monitoring the number change of the weighing sensor in real time;
and responding to the fact that the readings of the weighing sensors are not changed within the preset time, judging that the cargoes are completely loaded on the vehicle, and starting to carry out vehicle-mounted weighing work.

The first inclination direction is the inclination angle of the vehicle body in the horizontal direction, and the first inclination magnitude is the inclination amplitude of the vehicle body in the vertical direction.
It should be noted that, at a certain time of the gas in the tire, the pressure in the tire is related to the volume of the tire, and therefore, the amount of deformation of the tire can be obtained by the tire pressure. The inclined direction is that the vehicle inclines to the plane of four directions of front, back, left and right, and the inclination is the degree that the vehicle inclines to two directions of top and bottom.
Optionally, obtaining a first inclination azimuth and a first inclination size of the vehicle body according to the deformation amount of each tire; the method comprises the following steps:

The second dynamometry data is that the installation position and the installation height of the experimental weighing sensor are collected to the inclination position of the vehicle-mounted box body to each contrast inclination position and the inclination size to each contrast inclination size, and when the weighing sensor is consistent with the inclination position and the inclination size, the influence of the readings of the inclined friction force symmetrical retransmission sensor can be ignored. The tilt compensation coefficient obtained by the experiment is accurate.
According to the embodiment of the invention, the deformation quantity of the tire is obtained through the tire pressure, so that the inclination direction and the inclination size of the vehicle body are obtained, and in such a measuring mode, a new inclination measuring component is not required to be added, so that the resource waste is reduced, and the accuracy is higher.
