20120068860 | Traffic Control Database And Distribution System - A database for storing intersection data efficiently is disclosed. The database stores two or more points for each approach to the intersection along with the intersection control type. A third point can be used to help define the geometry of each approach. The database can be used with a warning system or any other vehicle system. The system may use approach point and intersection control type information to provide warnings to drivers of the motor vehicle when the motor vehicle is approaching the intersection at such a speed that the motor vehicle cannot safely stop. Methods for distributing the database information are also disclosed. The methods include pre-installed databases, dealer installed databases and on-demand distribution of intersection information. | 03-22-2012 |
20120139775 | Method for Testing GNSS-Based Positioning Systems in Obstructed Environments - Methods of testing GNSS-based positioning systems in obstructed environments may include specifying a required accuracy threshold for use in determining a reference trajectory. One or more difficult areas of relatively poor or missing GNSS availability may be located within the obstructed environment. Positioning information may be established for first reference points outside the difficult areas. Subsequently, by surveying with respect to the first reference points, positioning information may be established for second reference points within the difficult areas. The first and second reference points may then be used to determine a true path associated with the reference trajectory. When an improved GNSS-based positioning system is navigated along the reference trajectory, a set of measured points may be gathered, and errors between the true path and a measured path (derived from the measured points) may thereby be evaluated with respect to statistical characteristics, or to other improved GNSS-based positioning systems. | 06-07-2012 |
20120268262 | Warning System With Heads Up Display - A warning system for a motor vehicle includes a head up display. The warning system detects a remote vehicle that presents a potential hazard to a host vehicle, determines if the remote vehicle is visible to the driver and displays an image onto a combiner of the heads up display corresponding to a current location of the remote vehicle or a future location where the remote vehicle will appear on the combiner. In some cases, the combiner is a windshield or window of the motor vehicle. | 10-25-2012 |
