Power Split

In order to achieve better performance of fuel consumption in hybrid vehicles, the internal combustion engine is controlled to operate under a better efficient zone and often turned off and on during driving. However, while starting or shifting the driving mode, the instantaneous large torque from the engine or electric motor may occur, which can easily lead to a high vibration of the elastomer on the driveline. This results in decreased comfort. A two-mode power-split hybrid system model with elastomers was established with MATLAB/Simulink. Vibration reduction control strategies, Pause Cancelation strategy (PC), and PID control were developed in this research. When the system detected a large instantaneous torque output on the internal combustion engine or driveline, the electric motor provided corresponding torque to adjust the torque transmitted to the shaft mitigating the vibration. To the research results, in the two-mode power-split hybrid system, PC was able to mitigate the vibration of the engine damper by about 60%. However, the mitigation effect of PID and PC-PID was better than PC, and the vibration was able to converge faster when the instantaneous large torque input was made. In the frequency response, the effect of the PID blocking vibration source came from the elastomer was about 75%, while PC-PID additionally reduced 8% by combining the characteristics of the two control methods.

This article looks at some comparative statistics on the development and use of electric vehicles (hereinafter referred to as EM) as an example of sales and future sales forecasts for EM in countries that focus on environmental conservation. Examples of financial investments already underway and to be made in the near future by the largest automakers in the development and distribution of EM in the world are given. Steps are taken to improve the environmental situation in countries (for example, the prohibition of entry into the city center), the scientific and applied problem of improving the energy efficiency and environmental safety of the operation of wheeled vehicles (hereinafter referred to as the CTE). The basic and more widespread schemes of conversion of the internal combustion engine car (hereinafter -ICE) to the electric motor car (by replacing the gasoline or diesel electric motor), as well as the main requirements that must be observed for the safe use and operation of the electric vehicle. The problem is solved by justifying the feasibility of re-equipment of the KTZ by replacing the internal combustion engine with an electric motor. On the basis of the statistics collected by the State Automobile Transit Research Institute on the number of issued conclusions of scientific and technical expertise regarding the approval of the possibility of conversion of a car with an internal combustion engine (gasoline or diesel) to a car with an electric motor (electric vehicle), the conclusions on the feasibility of such conclusion were made.

To avoid unnecessary power loss during switching between the various power sources of a composite electric vehicle while achieving smooth operation, this study focuses on the development and dynamic simulation analysis of a control system for the power of a parallel composite vehicle. This system includes a power integration and distribution mechanism, which enables the two power sources of the internal combustion engine and electric motor to operate independently or in coordination to meet the different power-output requirements. The integration of the electric motor and battery-charging engine reduces the system complexity. To verify the working efficiency of the energy control strategy for the power system, the NEDC2000 cycle is used for the vehicle driving test, a fuzzy logic controller is established using Matlab/Simulink, and the speed and torque analysis of the components related to power system performance are conducted. Through a dynamic simulation, it is revealed that this fuzzy logic controller can adjust the two power sources (the motor and internal combustion engine) appropriately. The internal combustion engine can be maintained in the optimal operating region with low, medium, and high driving speeds.

The 19Th Century

This article focuses on the engineering credit that should be given to the bicycle designs and its hand in today’s technological innovations. Design improvements during the first 90 years of the bicycle’s history provided much of the initial technology that was extended to modern motorized forms of transportation. More important than the bicycle’s effect on the close of the 19th century was its influence on the 20th. The most common hybrid vehicle of the future may not be the now familiar four-wheel automobile combining an internal combustion engine and electric motor, but the electric bicycle that can be powered either by a rider’s muscles or energy stored in a battery. A development like that would be almost full circle. The only difference between that future and the first safety bicycle would be that electric power was harnessed along the way.

Multiple Configurations

Several hybrid architectures have been widely used in hybrid electric vehicles. For example, power-split architecture brings seamless operation, while parallel architecture makes the internal combustion engine directly drive the wheel. To combine the advantages of various architectures, this study aims to develop a design approach to create a transmission mechanism that has multiple configurations and uses these configurations to achieve several hybrid architectures. First, this study standardized hybrid transmission mechanisms using the Function Power Graph; this powerful and intuitive tool inspired several elements and an element layout for the new mechanisms. Then, several configurations with up to five elements were enumerated and organized into the databases. Next, the mechanisms with multiple configurations and a limited number of clutching units (clutches or brakes) were evaluated, 10 of which were identified as the best group that provided five parallel configurations, two 2-motor electric vehicle configurations, and a power-split configuration. At the end of this paper, a novel hybrid transmission mechanism was developed as a demonstration. It provides higher power and torque at the output but there is no need to use the larger internal combustion engine or motor-generators. This mechanism also enables the internal combustion engine to drive in overdrive parallel architectures to avoid the loss in energy conversion when the power-split architecture is not required. As a result, after a designer specifies the desired hybrid configurations, follows the procedure, and uses the configuration databases built in this study, a novel hybrid transmission mechanism will be created.

The article is devoted to the development of a generalized methodology for calculating the joint characteristics of an internal combustion engine and transmission of a mobile unit. The technique allows considering transmissions of various physical nature: electric, hydraulic. The peculiarity of the technique is that the power transmission of any physical nature can be represented by a generalized model, a four-terminal device, the input of which is affected by the values of Мin, nin, and the output is Mout, nout. As a result of the calculations, graphical dependencies of the joint characteristics of the internal combustion engine and transmission, the efficiency of the generator and the electric motor, and the mechanical and electromechanical characteristics of the electric motor are obtained.
