A Haptic Gearshift Interface for Cars

A Haptic Interface for Automobile Gearshift Design and Benchmark

Design, ergonomics and haptic feedback are features critical to the development of an eye-catching automobile gearshift. Manufacturers have to design and test a large number of prototypes, with different transmissions, dynamics, etc., before an appealing and marketable solution can be found. This paper introduces a haptic interface for automobile gearshift design and benchmark. It allows automo...

Simulation of the Admittance Control Based Haptic Interface Device

Simulation of a Manual Gearshift with a 2 DOF Force-feedback Joystick

A 2 dof force-feedback joystick was employed to simulate the force response of a manual gearshift of car during drive. The control law is based on an hybrid model. A state machine determines the active state of the system, according to the simulation, and changes the parameters of the dynamical model. The operator can move the gearshift lever whether such a movement would be allowed in an actua...

Haptic simulation of a gear selector lever using artificial potential fields

In this paper, we address the problem of haptic simulation of a gear selector lever using a two degrees–of–freedom mechatronic lever. To reproduce the behavior of a customary gearshift, we propose suitable virtual artificial potential fields that generate the desired force profiles. The artificial potential functions are based on generalized sigmoid functions and contain parameters that have in...

Towards a virtual environment for biomechanical simulation

In this paper we present an extendable framework for interactive biomechanical simulation and surgical planning. Three dimensional reconstructions of patient specific data are visualized and the elastic properties of individual anatomical structures are modeled. To avoid interpenetration of the virtual objects fast collision detection has been implemented. The kinematics are controlled by a spe...
