Design and Evaluation of Haptic Interface Systems for Motorbike Application Using Multibody Modelling

In this paper, the design and the evaluation of haptic HMI systems for motorbike are presented. The final goal of designing haptic interfaces is to set a communication between the rider and the motorbike increasing the rider safety. The designed systems have been evaluated through simulation using MSC Adams'®. Considering the possibility of a future realization of the simulation tested system, the haptic HMI devices have been designed taking into consideration a wide number of specific requirements. Starting from the state of the art, a preliminary study has been done in order to determine the design requirements. Three solutions have then been modelled: the Haptic Brake Lever, the Haptic Handle and the Haptic Knob. Each of the models has been tuned through simulations to convey the optimal haptic feedback to the rider, in terms of amplitude and frequency. In the end, the three solutions have been compared basing on safety, feedback perceivability, design and mechanical efficiency. The best solution will be realized and tested on a real motorbike during future work.
