MODELS AND SIMULATIONS OF TRANSMISSION OF HYBRID AND ELECTRIC VEHICLES

All systems in the construction of vehicles can be grouped logically, either as a structural system or control system. Structural systems consist of one or more sub-systems, as well as the optional files that define the system. Structural systems do not contain models, but only describe the structure, connecting systems and subsystems. The control systems consist of a model which defines the behaviour of the system and all the files needed to support or calculation of the output value of the system. Models and control systems include mathematical equations that describe the functions of the system or subsystem. Both of these types of systems are arranged in a hierarchical manner in order to define a vehicle that will be simulated. To avoid confusion, the best solution is to replicate the composition of the actual system, as far as possible. For example, small controllers should be grouped with the components they control, at various hierarchical levels wherever possible. Also, only systems that really are in the vehicle should be represented, in other words, there is no need for the unused components or space controllers. In addition to simplifying the construction, this concept will allow easy transfer between users and the system will be fully supported hardware and software, while ensuring effective control of the prototype, according to the needs.
