Transport weight device operates as follows.

Under the influence of the weight of the vehicle tires 2 wheels are deformed. The deformation of the tires of the 2 wheels depends both on the mass of the vehicle and on the air pressure in the tires 2. The signals from the strain gauge sensors 1 and the pressure sensors 3 are fed to the multi-channel amplifier 5. From the output of the multi-channel amplifier 5, the signals are transmitted to the analog code converter 6 and further to block 7 of the memory. Thus, two signals are supplied to the memory unit 7 from each bus 2: one from the strain gauge sensor 1, and the other from the pressure sensor 3. The number of pairs of signals entering the memory unit 7 is equal to the number of tires of the vehicle. The memory unit 7 is an electronic microprocessor system. The vehicle’s mass values are entered in its memory, which must correspond to the combination of signals from sensors 1, 3. Based on the sensor signals, the memory unit 7 selects from the memory a code that corresponds to this combination of signals. This code is the encoded value of the vehicle mass corresponding to this combination of signals. From the memory unit 7, this encoded mass value enters the analog code converter 8, and from it to the information display device 9 installed on the vehicle dashboard.

If necessary, the driver reads this information from the device.

Combinations of sensor signals and the corresponding encoded mass values are recorded in the memory of the memory unit 7 at the factory by loading the vehicle with standard loads of different masses with different locations of the vehicle's center of gravity and reading signals from sensors 1, 3 for each load case.

Determination of the uniformity of cargo in a vehicle is as follows.

The signals from the n-outputs of the converter 6 analog code are fed to the n-inputs of the block 10 determine the unevenness of the load in the vehicle and, accordingly, to the n-inputs of the block 15 of the memory.

The combination of the combination of sensor signals and the corresponding encoded mass values are recorded in the memory of the memory unit 15 at the factory by loading the vehicle with standard loads of different masses with different locations of the vehicle's center of gravity and reading signals from sensors 1, 3 for each loading variant.

Block 15 of the memory performs the following algorithm:

- determination of the average mass of the cargo in the form of an expression

where m is _full - gross vehicle mass, n is the number of control points on the surface of the vehicle;

- determination of the mass of cargo at each control point on the surface of the vehicle;

- determination of the difference in cargo mass relative to the average value at each control point on the surface of the vehicle;

- determination of the uneven distribution of the mass of the cargo at each control point on the surface of the vehicle in case of exceeding the magnitude of the difference in the mass of the cargo relative to the specified value.

In the case of uneven loading of the vehicle, the n-outputs of the memory unit 15 receive a combination of signals at the n-inputs of n-decoders 16. At the output of one or more decoders 16, a signal or signals are supplied to the inputs of one or more n-indicators 11 of uneven signaling placing cargo in a vehicle.

Information support of the vehicle loading process is as follows.

The signal from the output of the converter 8 code-analog is fed to the input of the analysis unit 12 of the vehicle loading process and, accordingly, to the input of the differentiating circuit 22, as well as to the first inputs of the first 17, second 18 and third 19 threshold devices, the second inputs of which receive signals from the output setter 20 signals.

From the output of the differentiating circuit, the signal is supplied to the second inputs (zeroing inputs) of the shift register 24 and counter 28.

As the vehicle loads, the signals from the outputs of the first 17 and second 18 threshold devices, through the OR element 21, are fed to the first input of the shift register 24, the third input of which receives a signal from the output of the pulse generator 23.

From the first and second outputs of the shift register 24, the signals are respectively supplied to the first and second inputs of the first 26 of the And element, through the element NOT 25 and directly, while from the output of the pulse generator 23, the signals through the third input of the first 26 of the And element are fed to the first input of the counter 28. From the output of the counter 26, the signal corresponding to the vehicle loading speed is fed to the second input of the second 27 element I.

At the moment of operation of the second 18 threshold device, a signal is supplied to the first input of the second 27 And element, the output of which goes to the indicator 13 of the predicted time of the full load of the cargo into the vehicle.

At the moment of operation of the third threshold device 19, a signal corresponding to the total mass of the vehicle is fed to the input of the indicator 14 of the full vehicle load.

Thus, along with obtaining information about the total mass, uneven distribution of cargo in the vehicle, information support is provided for the vehicle loading process.
