Abstract in different language: The term of Hybrid Electric Vehicle (HEV) represents the vehicle as a general mechanical system which cannot be structurally modified (for example by a different type of engine), but the modification from point of view the driving processes can be done by using a suitable control strategy. The control strategy is a very broad term which consist many control possibilities, many control strategies etc. but it is possible to divide it unequivocally into many different control levels. The introduced control levels can be further subdivided in the two groups with respect to the type of controlled processes. The first mentioned group represents control processes that may be fixed only on the past and present vehicle states (for example the level of electric voltage is controlled by rectifier regulator with respect to the current state of charge). The second group is represented by processes that can be controlled based on the past, present and with look into the future - control with prediction horizon (for example the heating can be switched on before a significant outdoor temperature change, because the vehicle bodywork has some thermal capacity). The special cases of these controlled processes are processes with discrete control strategy, typically for example gear switching, which can be done before the following slope and not in the slope. The other similarly control processes in the group of the same control levels may be considered the problems with vehicle physical bounds, for example maximal engine power, maximal value of the friction forces between tire and road surfaces etc. that may be represented as an bangbang control problem.
