Abstract
Apparatus to simulate driving a land vehicle comprising a fixed base platform, a mobile platform disposed above said base platform, a mobile driver's position, associated with the mobile platform and in which a driver has his seat during normal use, and movement means associated with the base platform and with the mobile platform to provide the movement of said mobile platform with respect to the base platform.
Claims6
An apparatus to simulate driving a land vehicle, comprising:
- a fixed base platform, wherein the fixed base platform is provided with a flat support surface;
- a mobile platform disposed above said fixed base platform on said flat support surface;
- a mobile driver's position associated with the mobile platform, wherein said mobile driver's position includes a seat for a driver;
- movement means associated with the fixed base platform and the mobile platform,
- wherein said movement means are configured to allow said mobile platform to slide on said flat support surface,
- said movement means including three first linear actuators associated with respective ends of said fixed base platform and respectively to said mobile platform,
- wherein each of said three first linear actuators are disposed on a plane parallel to said flat support surface,
- wherein said three first linear actuators are configured to translate said mobile platform in a first direction, translate said mobile platform in a second direction coordinated with respect to the first direction, and rotate said mobile platform around a third direction normal to said flat support surface and coordinated with respect to the first direction and the second direction in order to simulate great accelerations in surge, sway, and yaw movements associated with driving the land vehicle;
- a kinematic mechanism disposed entirely above said mobile platform,
- said kinematic mechanism being associated with said mobile platform and with said mobile driver's position to move the mobile driver's position with respect to the mobile platform,
- said kinematic mechanism comprising six second linear actuators provided to move said mobile driver's position in all six degrees of freedom;
- and
- a processing and control device configured to control independent and synchronized actuation of electric motors associated respectively with the first linear actuators and the second linear actuators,
- wherein said processing and control device is configured to implement mathematical algorithms comprising motion cueing algorithms.
