A full motion racing simulator is configured based on a real motor vehicle and includes wheels, a vehicle frame, and an actuating system for pivotably supporting the vehicle frame on the wheels. The actuating system includes a plurality of actuating assemblies each including a connecting structure pivotably connecting the vehicle frame to a corresponding one of the wheels, an actuator pivotably mounted to the vehicle frame, a push element pivotably connected to the connecting structure, and a rocker arm rotatably mounted to the vehicle frame and pivotably connected to the actuator and the push element. Upon actuation of the actuator, the actuator causes the rocker arm to rotate relative to the vehicle frame and to push the push element such that the push element causes the connecting structure to pivot relative to the wheels and to move the vehicle frame.

Method and systems for executing an interactive computer simulation of a simulated vehicle. A central repository comprises a synthetic natural environment database (SNEDB) that comprises data for a plurality of geographically-located terrain skin representations of a computer generated. A remote data management system maintains the remote repository comprising a subset of the SNEDB accessible to an interactive computer simulation station. The interactive computer simulation station sends, over the network, a data request for geographical locations from the SNEDB and allows users to interact in the interactive computer simulation for controlling the simulated vehicle. The remote data management system computes a plurality of expected geographical positions for the first simulation station and anticipatorily updates, via the network, the subset of the SNEDB stored in the remote repository with a supplemental subset of the SNEDB corresponding to one or more of the computed expected geographical positions.

A simulation device includes an outer frame and an inner frame. The outer frame is fixed to a floor surface and the inner frame is slideably interfaced to the outer frame. The inner frame has an inner frame axis. A hydraulic cylinder is interfaced between the outer frame and the inner frame. Operation of the hydraulic cylinder slides the inner frame with respect to the outer frame along the inner frame axis. A yaw platform is interfaced to the inner frame at one end at a pivot and at a distal opposing end by two or more bearings. The yaw platform has a yaw platform axis. Operation of a yaw motor or a yaw hydraulic ram interfaced between the yaw platform and the inner frame causes the yaw platform to change an angle between the inner frame axis and the yaw platform axis, providing simulation of yaw (loss of control).

In one or more embodiments, driver awareness may be calculated, inferred, or estimated utilizing a saliency model, a predictive model, or an operating environment model. An awareness model including one or more awareness scores for one or more objects may be constructed based on the saliency model or one or more saliency parameters associated therewith. A variety of sensors or components may detect one or more object attributes, saliency, operator attributes, operator behavior, operator responses, etc. and construct one or more models accordingly. Examples of object attributes associated with saliency or saliency parameters may include visual characteristics, visual stimuli, optical flow, velocity, movement, color, color differences, contrast, contrast differences, color saturation, brightness, edge strength, luminance, a quick transient (e.g., a flashing light, an abrupt onset of a change in intensity, brightness, etc.).

A method validates an obstacle identification system. In order to be able to demonstrate that obstacles are identified by an obstacle identification system at least as reliably as by a driver, it is provided that, in order to form driving scenarios, stochastic combinations of prespecified distributions of submodules are provided. The provided combinations are subjected first, for carrying out a simulation study, to simulation by a simulator and second to automatic processing by an obstacle identification algorithm of the obstacle identification system, and a result of a simulation study, which is carried out by the simulator, and a result of the automatic processing are automatically tested for agreement.
