701416000 | Regenerating entirely new route from current position | 9 |
20120072107 | Route Search Device, Server Device and Navigation Device - A route search device includes: map data; a derived route acquisition section that acquires a first derived route from an origin point to a destination; a route correction region acquisition section that acquires a route correction region; a place to be passed through setting section that sets a place to be passed through in the route correction region; a start point and end point setting section that sets a start point and an end point in the route correction region; a corrected route acquisition section that acquires a corrected route; and a route correction section that corrects the first derived route to a second derived route from the origin point to the destination, constituted by a route from the origin point to the start point, the corrected route, and a route from the end point to the destination. | 03-22-2012 |
20120072108 | METHOD FOR DETERMINING THE LENGTH OF THE ROUTE TRAVELLED BY A VEHICLE - A method for determining the length of the route travelled by a vehicle using a position measuring device that records positions of the vehicle and a digital road map, which is composed of road segments of known segment lengths. The method including recording positions of the vehicle on the route by means of the position measuring device, matching the recorded vehicle positions to a sequence of road segments, and determining the route length from the segment lengths of these road segments, wherein from the angle between at least two consecutive road segments and an assumed road width of the two road segments, a turn-off route of the vehicle from the one road segment into the other road segment is calculated. The calculated turn-off route is taken into consideration in the determination of the route length. | 03-22-2012 |
20120271543 | GPS NAVIGATION - A method of GPS navigation includes receiving a request for a new route, determining the new route, removing known GPS signal-loss areas from the new route to create a loss-free route, and providing the loss-free route. | 10-25-2012 |
20120303264 | OPTIONAL RE-ROUTING - Disclosed herein are tools and techniques for providing optional re-routing. In one exemplary embodiment disclosed herein, a determination is made that a location of a computing device is not on a predetermined route between a start location and an end location. Based on the determining, a re-route option is provided. Also, while the re-route option is available, a determination is made that a subsequent location of the computing device is on the predetermined route, or a re-route is performed responsive to receiving a touch-anywhere input event on a touchscreen display. | 11-29-2012 |
20130006519 | Method and Decreasing Position Error during Turn-by-Turn Sessions - The described method and system provide for GPS navigation utilizing an EHPE (estimated horizontal positioning error) timer for reducing route calculation failures. By utilizing an EHPE timer, a GPS unit may continue to check for GPS signal until the EHPE timer expires before reporting route calculation failure to the user. Thus, in situations where GPS signal is only temporarily lost and current location information is only temporarily degraded, user route requests will not necessarily result in route calculation failure. In preferred implementations, the system and method are implemented within the context of a telematics unit in a vehicle or in the context of a call center. | 01-03-2013 |
20140019038 | AIRCRAFT SYSTEM AND METHOD FOR IMPROVING NAVIGATION PERFORMANCE - A high integrity navigation system and method are provided. The method comprises performing a cyclic redundancy check (CRC) of a desired flight path of an aircraft, for example an approach to an airport, and comparing the CRC with a stored CRC performed on the identified flight path. If the comparison exceeds a first threshold, a first alert is provided wherein the pilot is to perform a published missed approach. A second alert, also requiring a missed approach, is provided when one or more comparisons are performed of a sensor position of the aircraft with the high integrity flight path; a defined flight path with the high integrity flight path; and the sensor position with an aircraft position determined by a flight management system, and thresholds are exceeded. | 01-16-2014 |
20140114564 | MOBILE NAVIGATION TO A MOVING DESTINATION - A source device can navigate towards a moving destination target device, such as when two mobile phones are moving towards each other. The source device can receive an initial position of the target and a route to the target. As the source device and target device simultaneously move, the route can be updated. For example, if a distance of movement exceeds a threshold (e.g., 1 mile) the route can be updated. In another embodiment, a target device can switch between position tracking devices so as to provide less accurate position information, but save power, or provide high accuracy position information at the cost of higher power consumption. Generally, the switching between position tracking devices and the frequency at which the route to the destination point can be based on the distance apart between the source device and target device. | 04-24-2014 |
20140200802 | OPTIONAL RE-ROUTING - Disclosed herein are tools and techniques for providing optional re-routing. In one exemplary embodiment disclosed herein, a determination is made that a location of a computing device is not on a predetermined route between a start location and an end location. Based on the determining, a re-route option is provided. Also, while the re-route option is available, a determination is made that a subsequent location of the computing device is on the predetermined route, or a re-route is performed responsive to receiving a touch-anywhere input event on a touchscreen display. | 07-17-2014 |
