Table 6: Comparative analysis of more modern diagnostic methods with the method proposed (own elaboration on based literature studies). Figure 4: Classification of technical diagnostic systems in road transport. The research was continued based on two assumptions:  
**Assumption 1**. : _The efficient operation of vehicles designed for transporting heavy and oversized loads requires continuous monitoring of the entire vehicle, including the area occupied by the load._  
**Assumption 2**. : _Realizing Assumption 1 necessitates creating a concept for an integrated platform for diagnosing, predicting, and mapping faults on a 3D monitor. This platform should actively alert truck drivers to existing or potential faults and provide visual interpretations of the information displayed._
