The article shows that the existing methods of determining the trucks reliability do not take into account the level of load effect during the operation. Depending on climatic conditions, road surface categories, carrying capacity use conditions and technical service quality, the cumulative value of the load impact will vary and affect the reliability index. The purpose of the work is to identify the relationship between the reliability indices and the cumulative value of the impact, as well as a graphical interpretation of these dependencies using three-dimensional reliability process charts. In the paper the methods determining the accumulation rate of loading effects on vehicles and their impact on the probability of failure-free operation and the failure rate of trucks are used. The sequence of collecting statistical data on failures and operating conditions is given. The theoretical bases determining the operating reliability indices dependence on the loading action level are also discussed. The sequence of three-dimensional reliability process charts construction is presented. The obtained results give the possibility of updating the modes of maintenance for various makes and models of commercial vehicles taking into account the operating conditions.
