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.

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.

Working Processes

The diagnostic testing of internal combustion engine can be made by using working processes and methods which take advantage of leftover processes. Working processes give information about general condition of internal combustion engine. Leftover processes give information about condition of particular subassemblies and kinematic couples; hence they are used as autonomous processes or as processes supporting other diagnostic methods. Methods based on analysis of vibrations and noise changes to determine technical condition of object are named as vibroacoustic diagnostics. In papers about vibroacoustic diagnostics of engine, problems connected with difficulty to select test point and to define diagnostic parameters containing essential information about engine’s condition, are most often omitted. Selection of engine’s working parameters and conditions of taking measurements or recording vibration signal are usually based on references, researcher’s experience or intuition. General assumptions about taking measurements of signal closest to its source are most often used. This paper presents a new approach to vibroacoustic diagnostics of internal combustion engine. Selection of test points of vibration on the basis of impact tests results was suggested and performed a sensitivity analysis of measurement points on the cylinder head, the force impulse.

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.

Key Factor

At the end of the 19th-century three technologies had emerged as sources of motive power for the automobile: steam, internal combustion, and electric motors. In 1900, in the United States and around the world, each of these powered a roughly equal number of automobiles. Thus, the early period of automobile development offers fertile ground for the study of technological path choice. At that time, it appeared that the electric motor was poised to become the dominant automotive technology. However, the internal combustion engine achieved this status instead. Although a large number of studies have examined the history of the automobile with a view to determining the reasons for the emergence of the internal combustion engine as the dominant technology for the car engine (especially its choice over the electric motor), no consensus has emerged of what the critical factors were. A close reexamining of the history allows us to identify the years 1900-1904 as the period during which the automobile’s technological path was determined. A review of the conditions prevailing during this period and the stages of development of the sociotechnical systems in which each of the alternative automotive technologies was embedded helps us identify the aspiration for touring as the key factor fixing the path for the technological development of the automobile from that point on.

Hybrid Power Plant

The problem of control of a hybrid power plant of a car consisting of an internal combustion engine, a synchronous electric motor with permanent magnets and a synchronous generator is considered. The formation of the control effect is carried out taking into account the connection of the above objects with each other with the help of planetary transmission. The mathematical models of the three listed engines are nonlinear with several control channels. In addition, the principle of the hybrid power plant requires the simultaneous operation of these engines and, accordingly, the construction of the necessary interrelated control actions. To synthesize the laws of vector control of a hybrid power plant, the method of analytical construction of aggregated regulators (ADAR) is used. Within the framework of this method, it is possible to work with a complete nonlinear control object model. Unlike the traditional approach of constructing a separate stabilizing control for each control channel, this method uses co-control over all variables to transfer the object to the desired state. In this case,for a number of variants of control algorithms, the communication between the control channels is carried out not indirectly, through the control object, but directly formed in the regulator. In addition, the control law takes into account unknown external disturbances, which were compensated using the principle of integral adaptation. In this paper, one of the modes of operation of a hybrid power plant is shown during the acceleration of the car. First, only the electric motor works, as the car accelerates, the internal combustion engine is connected, and at high speeds only the internal combustion engine works. This mode of operation of the hybrid power plant allows using both engines in the most convenient range of angular speeds, which leads to an economical fuel consumption and a charge of the storage batteries. In addition, the second electric motor operates in the generator mode and transfers a part of the mechanical moment to recharge the batteries.
