Evaluation of the use of hybrid electric powertrain system in urban traffic conditions

Abstract

The conditions of use of the vehicle significantly affect the performance results. Traffic conditions in a specific city directly affect the consumption of energy, fuel and emissions of harmful compounds in exhaust fumes. Conduction of the measurements of a vehicle’s performance parameters in operating conditions is very troublesome and is often not possible to realize. An alternative is to use the simulation programs. Vehicle simulation programs offer options related to vehicle models or drive unit components and allow development of new models. Based on the results of simulation testing, it is possible to analyse the level of fuel and energy consumption as well as emissions of harmful compounds in exhaust gases and the operating effectiveness of the drive system in the speed profile. The paper presents the evaluation of the effectiveness of using hybrid electric drive system in passenger cars in medium-sized city traffic conditions using the Kielce example. The simulation tests were based on the speed profiles recorded during real-world test drives in various times of the day. The simulation results were used to conduct an analysis of fuel consumption and pollutant emissions recorded by conventional and hybrid vehicles.

Integration of a Chassis Servo-Dynamometer and Simulation to Increase Energy Consumption Accuracy in Vehicles Emulating Road Routes

“…These dynamometers may vary drastically in their components and operation based on the particular needs of each vehicle manufacturer or research institution [37]. Amongst the different types of dynamometers used, this research focuses on those where the entire vehicle powertrain (often with chassis and cabin) is placed on rollers to simulate driving conditions.…”

The Environmental Safety of the Fiat 0.9 TwinAir Compressed Natural Gas Engine

“…In recent years, the automotive industry has been showing trends towards the development of electromobility [1,17,39]. Due to the significant share of transport in global greenhouse gas emissions, solutions are being sought to improve the environmental indicators relating to means of transport [27,36,46]. Despite significant investments in the development of electromobility means of transport, research on the further development of thermal engines is still ongoing, as evidenced by numerous research works, patents and implementations [8,19,38].…”
