DEVICE AND METHOD FOR EVALUATION OF VEHICLE FIT HEIGHT Russian patent published in 2016 - IPC B60G17/18 

FIELD: transport.

SUBSTANCE: vehicle fit height can be evaluated by inexpensive process. Number of revolutions of wheels including that of every wheel is defined (step ST11). Defined number of revolutions is subjected to frequency analysis for the pair of LH and RH wheels. Appropriate characteristics of the defined number of revolutions are subjected to frequency analysis for the pair of LH and RH wheels are calculated at specific frequency amplitude component (step ST12). The difference in said frequency amplitude components is calculated proceeding from the calculated characteristics of the defined number of revolutions is calculated for the pair of LH and RH wheels (step ST13). The vehicle fit height is evaluated proceeding from the appropriate interrelation between the wheel location height relative to the vehicle body and the magnitude of amplitude component of the wheels rotational speed/road pavement irregularity pulse. The latter is fed from the pavement to the wheels proceeding from the difference in said frequency amplitude components is calculated proceeding from the calculated characteristics of the defined number of revolutions for the pair of LH and RH wheels (step ST14).

EFFECT: development of inexpensive gadget for evaluation of the vehicle fit height.
