The work done for this thesis had the purpose of realizing an haptic simulator for a car gearshift whose aim was to replicate the real force profile behavior of several commercial cars mounting different gearbox models. The force profiles were obtained recording the forces of real gearshift engagement on those cars. The process has involved different phases, the choice of electronic components for the mechanical interface and the design of the software control architecture. A first analysis of the recorded forces was performed to draw the specification for the hardware components. A second analysis of the data led to the drafting of a model for the simulation and the creation of algorithms to process the force profiles. After that the high level control software for the force profile simulation was developed using the hardware at our disposal, despite the fact that it cannot fit all the specifications this choice has speeded up the development process. The high level application's work has involved the study of some physical phenomena that can ruin the operator's feeling, some control strategy were performed to overcome those issues and the results were compared against the recorded profiles to ensure the match between force recorded and force rendered by the interface.\\
Once obtained the new hardware the development of a low level software control interface was started, highlighting some limitations that have been overcome creating some filter algorithms. The low level software interface will be used in future works with the high level software application created for the simulation.
