Abstract: To address the significant discrepancy in road characteristics between current regulatory operating conditions and customers' actual operating conditions, this paper proposes a forward development method for vehicle power matching based on customers' actual operating conditions. Taking the standard-load transport tractor as the research object, it analyzes the characteristics of the vehicle's actual operating conditions, constructs typical operating condition road spectra for its segmented market, and simultaneously conducts forward demonstration to determine key parameters of the power system, including engine displacement, peak torque, rated power, and transmission ratio. Using simulation software, a vehicle dynamics simulation model is built. From the perspective of key performance indicators such as vehicle fuel consumption and power performance, forward demonstration is carried out for different powertrain matching schemes, and the optimal power configuration solution for the standard-load transport segmented market is finally proposed Continuous tracking and verification of market-operated vehicles show that the target vehicles with large horsepower+small speed ratio configuration have a fuel consumption reduction of 1.89 L per 100 km compared with other vehicles on the same route, and a single vehicle reduces carbon emissions by 5.34 t per year, achieving remarkable energy-saving and emission-reduction effects.
