20.500.12556/RUL-176507 Vehicle acceleration modeling with constant power manual, automatic and electric transmission This paper presents the acceleration process of vehicles with different transmissions. The focus is on accurately modelling this process and comparing the models with real-world test data. Constant power equations are developed for different transmissions, including electric, manual, and automatic transmission. The paper analyses the development of mathematical models for vehicle acceleration, taking gear change time into account and aiming to represent real road conditions accurately. This analysis examines the phenomenon of vehicle acceleration on flat asphalt surfaces, as the used accelerometer is automatically compensated for the gradient and provided results for a straight road with no gradient, which serves as a foundational component for traffic simulations. These simulations are essential in reconstructing various vehicular dynamics encountered in urban areas, such as rear-end collisions when driving in a column or vehicles accelerating through intersections. Researchers can effectively replicate real-world scenarios by comprehensively understanding vehicle acceleration, offering invaluable insights for accident investigation, safety assessment, and other related fields. The paper compares theoretical models with real-world test data. The model has been expanded with an algorithm that enables the determination of model parameters from the measured acceleration values. The results indicate that the measured acceleration from initial speed to constant velocity for different transmissions is similar to the theoretical curve. On average, the ratio of nominal engine power to power consumption for acceleration to constant velocity is approximately 50% of the nominal P/m value and 80% of the maximum surface load. The vehicle and driver characteristics can be assumed to account for approximately 50% of the nominal P/m value and 80% of the maximum surface load. It is important to note that these results cannot be generalized as the outcomes may vary depending on how the driver accelerates. acceleration transmission automatic transmission manual transmission electric transmission constant power accidents cestna vozila menjalniki pospeševanje true false true Angleški jezik Slovenski jezik Članek v reviji 2025-12-02 14:22:35 2025-12-02 14:22:36 2026-02-06 14:56:27 0000-00-00 00:00:00 2025 0 0 Str. 528-537 Vol. 83 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 629.331 2352-1465 10.1016/j.trpro.2025.03.022 230694915 230609155 1-s2.0-S2352146525000705-main.pdf 1-s2.0-S2352146525000705-main.pdf 1 2F30A9D5F9B82E87C8D608593C058E0F 06cbf80e160b586f31fe0da86a0b2018ecd391428712fdae62897a1296dbd1b7 0984eefd-cf82-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=222881 https://www.sciencedirect.com/science/article/pii/S2352146525000705 1 9534f5da-cf81-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=222880 Fakulteta za pomorstvo in promet 0 0 0
