Hybrid power train with planetary transmission equipped with clutch-brake systems, which employ one electric machine, is more effective and more economical than other existing series-parallel hybrid power trains which need two electric machines as motor and generator. This paper presents the control method of zero steady-states electrical energy consumption clutch-brake systems in hybrid power train with planetary transmission. For different functions, the electromagnetically controlled clutch-brake systems in hybrid power train are modified into brake and dual-clutch based on the same basic structure. The control method of such clutchbrake systems as well as other components in hybrid power train is studied for internal combustion engine starting and gear shifting. The dynamic simulation model of hybrid power train with clutch-brake systems is built in Matlab/Simulink environment. By analyzing the simulation and bench test results, the control methods of clutch-brake systems are validated and the proper control are selected to get better performance for ICE starting and gear shifting.

“…Awrejcewicz and Grzelczyk studied the wear of clutch friction surfaces [18]. Being one of the most important component of a clutch system, the diaphragm spring (which determines clutch pedal load) is studied by some researchers and optimized for the best release load and durability [19][20][21][22][23][24][25]. Some researchers studied the Almen-Laszlo formula (which is used to calculate disc spring characteristics) [26] to improve its accuracy [27][28][29][30].…”

Abstract-Optimum design of a clutch and dual mass flywheel system is completed. Although the clutch systems are exposed to both rotational and axial vibrations, they are generally designed by considering rotational vibrations of engines and they do not have any component to damp axial vibrations due to the following two reasons: first, the package area of the clutch system is very limited and there is no available space to put additional springs and dampers to reduce these vibrations. Second, axial vibrations are normally insignificant to be considered in the analyses and such vibrations are supposed to be damped by the diaphragm spring and cushion springs. Nonetheless, axial vibrations may lead to some unexpected problems in the power train such as the rattle noise that is examined in this study by using global optimization techniques. The components in the clutch system are modeled analytically. Then, by considering the pedal characteristics and vibrations of pressure plate as objective functions, a multi-objective Pareto optimization problem is solved. It is shown that analytical models agree well with the experimental measurements and vibrations in the clutch system can be reduced significantly by choosing the design parameters with optimization tools.
