"The invention relates to a method of determining the own-vehicle(*自車両)position of a motor vehicle having a navigation system fixedly installed in the motor vehicle.
Modern motor vehicles are increasingly equipped with navigation systems, frequently even in series. Navigation systems fixedly installed in motor vehicles determine the position of the motor vehicle in which it is installed (in the following, also called “own-vehicle(*自車両)position”) within the global area imaged on a road map, usually on the basis of GPS or GNSS. Particularly in city center areas with blocks of high buildings, in tunnels or parking garages, the problem may arise that self-localization by GPS/GNSS is not easily possible, for example, because of shadowing and multi-path effects. The same may apply, or may especially apply, when the driver is driving into or out of a parking garage in the center of town."

"The present invention relates to a radar-based own motor vehicle(*自車両)movement sensor system (1) that can measure yaw rate relative to a road surface (15), and optionally also the velocity and/or the relative yaw angle of the vehicle (25) with respect to a direction of motion. The sensor system (1) comprises on the vehicle (25) a first pair of opposite directed radar sensors (2, 4), including a first radar sensor (2) and a second radar sensor (4) which provide respectively outputs (16, 18) representative of a rate of change of range from each respective sensor (16, 18) to the fixed surface (15), and a processing means (14) that receives the rate of change outputs (16, 18) from the sensors (2, 4) and that calculates therefrom the rate the change of yaw."

"In both the ground and air embodiments of the invention, a sound system 400 generates aural cues synchronized with and representative of actions and events in the virtual environment. Sounds can be caused by, for example, own vehicle(*自車両)and other vehicle(*他車両)movements, own weapon(*自兵器)and other weapon firing, weapon impacts and explosions caused by own weapons or other weapons, and could even include environmental “noise” such as crowd noise."
