“…1. Architecture of the parallel hybrid electric vehicle [7] It results from the greater versatility of such a drive system solution in everyday use, both in urban and extra-urban traffic [2,5,18,19]. Many authors conduct research on this type of hybrid drive systems in relation to the emission limits of harmful components [15,16] as well as in terms of total energy consumption in normal operating conditions [12,13,20] or in relation only to the electric drive system [6,19].…”

The analysis of energy consumption in a hybrid drive system of a passenger car in real road conditions is an important factor determining its operational indicators. The article presents energy consumption analysis of a car equipped with an advanced Plug-in Hybrid Drive System (PHEV), driving in real road conditions on a test section of about 51 km covered in various environmental conditions and seasons. Particular attention was paid to the energy consumption resulting from the cooperation of two independent drive units, analyzed in terms of the total energy expenditure. The energy consumption obtained from fuel and energy collected from the car’s batteries for each run over the total distance of 12,500 km was summarized. The instantaneous values of energy consumption for the hybrid drive per kilometer of distance traveled in car’s real operating conditions range from 0.6 to 1.4 MJ/km, with lower values relating to the vehicle operation only with electric drive. The upper range applies to the internal combustion engine, which increases not only the energy expenditure in the TTW (Tank-to-Wheel) system, but also CO2 emissions to the environment. Based on the experimental data, the curves of total energy consumption per kilometer of the road section traveled were determined, showing a close correlation with the actual operating conditions. Obtained values were compared with homologation data from the WLTP test of the tested passenger car, where the average value of energy demand is 1.1 MJ/km and the CO2 emission is 23 g/km.

“…The current technological trend of reducing emissions from vehicles are technologies that allow the use of alternative fuels or alternative drives themselves. Tests of vehicles powered with alternative fuels (ethanol, CNG, bi-fuel) or with alternative propulsion systems (full and mild hybrid system) are carried out with respect to energy flow [3,13,14,19] and their harmful components emissions in real operating conditions and in RDE (Real Driving Emissions) tests [5,[15][16][17].…”

The pursuit of fuel consumption reduction by vehicles leads to a sudden increase in the share of hybrid and electric drives in the vehicle market. Replacing hybrid vehicles with electric vehicles requires long-term technological solutions, both for the infrastructure and the vehicles themselves. Therefore, one of the leading types of passenger car drives is currently the hybrid drive. The generated work share of electric drives used to power hybrid vehicles is a determinant of the viability of using electric drives. The article estimates the operating time share of electric and hybrid modes operation in real driving conditions (RDC) based on the latest Toyota hybrid model. The research object was a vehicle from the crossover group equipped with a fourth generation hybrid drive. Analysis of the drives operation allowed to determine the conditions of energy flow and determine the work share of the electric drive in the total driving time.
