Abstract
The invention relates to a method for simulating the movements of a virtual vehicle, a user being in physical contact with a simulator including a force-feedback haptic interface, wherein said physical contact corresponds to at least one physical point of contact between the haptic interface and the body of the user that is representative of a virtual point of contact between the user and the virtual vehicle. Said method comprises at least two steps. A first step involves determining a linear acceleration vector (formula (I)) and a linear velocity vector (formula (II)) at the virtual point of contact between the user and the virtual vehicle, said vectors being representative of the movement of the vehicle at said point. A second step involves deducing a three-dimensional force vector (formula (III)) from the linear acceleration vector (formula (I)) and linear velocity vector (formula (II)), said force vector being predetermined by a linear combination of said linear acceleration and velocity vectors, the corresponding force being applied via the haptic interface substantially at the physical point of contact. The invention also relates to a device for simulating movements of a vehicle.
