Problems solved by technology
Although the phenomenon of overloading is relatively serious at present, there are still some law-abiding drivers who do not intend to overload, but because the existing vehicles are not equipped with a weighing system, these drivers can only rely on visual inspection when controlling overloading. unscientific
[0003] In addition, the phenomenon of unbalanced load of vehicles is relatively serious at present. After the occurrence of unbalanced load, it will seriously affect the safe driving of the vehicle. At the same time, the load shafts on both sides of the steering axle, drive axle, and bearing bridge are unevenly stressed and the degree of wear is also different.
[0004] Another problem is that the current suspension system of the car basically uses the airbag (air spring) as a buffer component. How to measure the air pressure value of these airbags is also a very troublesome problem during the running of the vehicle.

The invention relates to an automatic weighing system of an automobile, comprising a display instrument, an automobile running electronic control unit and a plurality of pressure sensors arranged in a cab. Gasbags of a steering axle, a driving axle and a bearing axle are respectively connected with a gas pipe, the gas pipe is connected with a pressure sensor, each pressure sensor is connected with one port of the automobile running electronic control unit through a data line and outputs a voltage signal of 0.5-4.5V to the automobile running electronic control unit, and the automobile running electronic control unit integrates various gasbag parameters and underspring weight data prestored in storage units thereof, calculates the axle deadweight and the total automobile weight of the steering axle, the driving axle and the bearing axle, the pure load and the passenger number through embedded weighing operation procedures and outputs the data through an output interface on the automobile running electronic control unit to the display instrument to be displayed.
Description
Technical field: [0001] The present invention relates to an automatic weighing system installed on a car, more specifically, it relates to a method of collecting the air pressure of an air bag through an air pressure sensor, converting it into a voltage signal and inputting it into the electronic control unit of the car for calculation, and displaying it through a display instrument It is an automatic vehicle weighing system that displays the axle loads of the steering axle, drive axle and bearing axle, as well as the total vehicle weight, net load, and occupants when the vehicle is in normal operation. Background technique: [0002] Vehicle overloading is a serious social problem, and controlling overloading is also a long-term work. The current method of controlling overloading is basically to set up checkpoints on the highway to check the vehicle overloading phenomenon. Once overloading is found, the management personnel will require the driver to unload before normal ope...
