“…Thanks to the use of an electric motor, the braking recovery system will be activated during braking, which will increase the power reserve of the car. In order to obtain optimal traction and dynamic characteristics of the three cycles and the selection of the electric motor, we perform traction and dynamic calculation [12]. The initial data for the traction calculation are shown in table 3.…”

The article considers the bolide Shell Eco Marathon, which main operating purpose is to cover the maximum distance with the minimum fuel consumption. With the aim of providing the bolide with technical and operational indicators, it is appropriate to solve the problem of decreasing the bolide’s mass, the air drag coefficient, and also the choice of the economic power plant. The basic formulas for the engine traction-dynamic calculation are presented. Due to the results of the calculation, the conclusion about profitability of the power plant is made. There is also a description of the principle of the electric engine and its main advantages comparing to the internal combustion engines.

“…Compared with electric hybrid vehicles, hydraulic hybrid vehicles overcome the problems of low energy recovery and battery affected by temperature, it has the advantages of long life, high reliability, easy maintenance, simple structure, high power density, flexible layout and so on. More and more attention is being paid to hydraulic hybrid vehicles with the development of vehicles towards energy saving and emission reduction [23][24][25]. Fanwei [26] used dynamic programming algorithm to optimize the control of hydraulic hybrid vehicle, established the objective function of engine energy consumption, and obtained the optimal parameters of energy consumption of hydraulic hybrid engine by optimizing the objective function.…”

The airports construction level is improved and the construction scale is constantly expanded with the rapid development of society, economy and science and technology, which brings a good development prospect for aircraft towing tractors. On the basis of summarizing the current research and application of aircraft towing tractors, the traction characteristics of towbar and towbarless aircraft tractors were analyzed, and the mechanical, electric, hydrodynamic and hydraulic transmission automatic control system were compared. The composition, working principle and application of hydraulic steering control system, hydraulic braking control system, hydraulic clamping and lifting mechanism and hydraulic hybrid power system of aircraft towing tractors were emphatically discussed. The results show that the configuration of towbarless traction is flexible and the traction capability is strong. Hydraulically controlled aircraft towing tractor has good traction, braking and control characteristics. Electronic hydraulic braking system is precisely controllable, and the hydraulic hybrid technology is beneficial to reduce the energy consumption of aircraft towing tractors. The demand for aircraft towing tractors is increasing with the expansion of the airport distribution and construction, on the basis of constantly improving the existing aircraft towing tractor and according to the needs of airport operation, it is necessary to adopt innovative technology to develop energy-saving, environment-friendly and intelligent aircraft towing tractors, so as to adapt the development needs of aviation industry.

“…The combustion is unstable at the initial stage of the engine ignition, resulting in a large fluctuation of engine torque. Thus, the torque of the hybrid system changes dramatically, and then transfers this to the whole vehicle, affecting the vehicle's ride comfort [27,28]. Therefore, it is necessary to coordinate the torque of the engine, the motor, and the wet clutch.…”

Driving mode switches of hybrid vehicles are significant events. Due to the different dynamic characteristics of the engine, motor, and wet clutch, it is difficult to coordinate torque fluctuations caused by mode switches. This paper focused on a control strategy for driving mode switches of plug-in hybrid electric vehicles (PHEVs) with a multi-disk wet clutch. First, the dynamic model of the PHEV was established, and a rule-based control strategy was proposed to divide the working mode regions and distribute the torque between engine and motor. Second, the dual fuzzy control strategy for a wet clutch and the coordinated torque control strategy for driving mode switches were proposed. The dual fuzzy logic control system consisted of the initial pulse-width modulation (PWM)’s duty cycle control and the changing rate of the PWM’s duty cycle control. Considering the difference in the dynamic characteristics between engine, motor, and wet clutch, a coordinated control strategy for the driving mode switches of PHEVs was put forward. Third, simulations of driving mode switches between pure electric driving mode and only engine driving mode were conducted. The results showed that the proposed control strategy could reduce the torque ripple and the jerk of the vehicle, completely satisfying the requirements of China. Finally, the control strategy for the motor-assisted engine starting process was tested on the bench. The experiment results indicated that the proposed control strategy was effective.
