A methodology for evaluating the efficiency of driving a truck

Abstract

The article considers the issues of evaluating the efficiency of converting thermal energy into mechanical work when operating pit vehicles - BELAZ-7540B dump trucks in mountain conditions and the role of the driving skills in this process. The article also defines the efficiency of driving a vehicle, based on which it presents a methodology and mathematical models for evaluating the driver’s efficiency. At the same time, the basis is formed by several operational indicators, out of which the most important ones for mountain operating conditions of heavy-duty trucks - dump trucks are energy, economic and reliability indicators. The driver’s efficiency is evaluated by the energy and economic indicators based on the trip fuel consumption and the performance of the vehicle - dump truck per shift. The efficiency of driving a heavy-duty truck - a dump truck by the material costs indicator is evaluated by the consumption of spare parts and repair and maintenance materials. The driver’s efficiency is evaluated by the reliability indicators based on the specific time, labor, and money costs spent on eliminating operational and resource failures.
