The article presents the issues of energy recovery in the hybrid drive system of a vehicle Toyota Yaris 1,5 Hybrid. Road tests of a vehicle equipped with a hybrid drive system were carried out in accordance with the recommendations of the RDE test. In these studies, measurements of braking energy recovery were carried out in urban, rural and motorway traffic conditions. The analysis of the obtained test results may constitute a premise for the creation of an appropriate strategy for the operation of the hybrid drive system in terms of meeting the requirements of the currently prepared Euro 7 standard.

The introduction of the Euro 6c emission norm in 2017 resulted in a change of the type approval procedures. The most important of these was the replacement of the NEDC test with WLTC test with different procedures. In addition, the research was extended to include emission tests in real operating conditions (RDE). Such tests are enforced for heavy vehicles since 2014. PEMS apparatus was used for the measurements, which has been used by many research and development centers to carry out exhaust emissions measurements long before the applicable procedures were introduced. The article presents the methodology of conducting RDE measurements in accordance with the requirements defined by the Euro 6c norm. The focus in this case was primarily on the selection of the test route in the Poznań agglomeration. After determining its course, RDE measurements were made for a vehicle with a hybrid drive. The test route parameters have complied with the applicable requirements. All requirements were met and it was possible to analyze the exhaust emissions. The main focus being the determination of exhaust emissions from the entire test and in accordance with the EMROAD method. The CF (Comformity Factor) coefficients were also determined for both methods and compared with the applicable legal values. An analysis of the hybrid drive system operation was carried out, defining the degree of hybridization, which is the portion of the vehicle travel using only the electric motor of the drive system throughout the whole test. All analyzes were carried out in individual sections of the test: urban, rural and motorway.

Continuously increasing share of the hybrid and electric vehicles in the global automotive market justifies the need for detailed analysis of the operational effectiveness of these drive systems. The aim of the study was to assess the operational conditions of the combustion engines and electric motors in hybrid drive systems – full hybrid – of the motor vehicles in urban traffic conditions. Variety of designs of such drive systems is related to the high voltage batteries used and the way of charging them. The road tests were conducted in Warsaw (urban traffic conditions) by recording the operational parameters of three vehicles and their driving systems. The conditions of operation of the combustion engine and electric motors along with the values of their high voltage battery charge level were related to the test routes. The analysis of the relative shares of engine and motor operation time in the total time of vehicle operation in urban traffic conditions was conducted. The scope of operation of the hybrid drive system utilizing only electric propulsion system was determined. The relations between the operational indexes of the hybrid propulsion (combustion engine and electric motor) in real traffic conditions and the charge level of batteries, current speeds and accelerations were shown.

Hybrid Drive

Motorbikes are a very popular means of transport, are mobile and suitable for transport infrastructure in Vietnam. At present, the number of motorcycles is  alarming (the number of registered motorcycles is about 70.4 million units over 94.4 million people). It contributes greatly in causing environmental pollution. The solution to install an electric motor on a motorcycle to reduce environmental pollution is a practical and economic benefit. This paper presents the design of the hybrid drive system of the traditional heat engine and electric motor on the motorcycle. Thereby, analyzing and evaluating  the test results of the designed system.

Braking Energy Recovery

The energy utilization is crucial for electric or hybrid vehicles to solve the problem of braking energy recovery, especially of low speed energy recovery. In this paper, the energy transform model of electric vehicle in braking state is analyzed, and the half bridge control main circuit was selected. The energy recovery strategies and methods on the breaking process of low speed were researched. The concrete realization of parameters decision and system control was given. The results show that the energy recovery strategy and electric vehicle model can improve the energy transform efficiency in low speed state.
