Modelling of the system "driver - automation - autonomous vehicle - road"

The work presents a simulation model of a "driver-automation-autonomous vehicles-road" system which is the basis for synthesis of automatic gear shift control system. The mathematical description makes use of physical quantities which characterise driving torque transformation from the combustion engine to the car driven wheels. The basic components of the model are algorithms for the driver's action logic in controlling motion velocity, logic of gear shift control functioning regarding direction and moment of switching, for determining right-hand side of differential equations and for motion quality indicators. The model is realised in a form of an application software package, comprising sub-programmes for input data, for computerised motion simulation of cars with mechanical and hydro-mechanical - automatically controlled - transmission systems and for models of characteristic car routes.
