    摘要: There is a need for improving the accuracy of estimating a gain error for an angular velocity sensor. An error estimation section and a correction section are provided as well as a gyroscope that detects an angular velocity of a vehicle. The error estimation section assumes the gain error of the gyroscope to be a state quantity and finds an estimated value for the gain error using a Kalman filter. Based on the gain error found by the error estimation section, the correction section corrects a gain correction amount used for gain correction of values detected by the gyroscope. The correction section corrects the gain correction amount dedicated to right turn based on the gain error found by the error estimation section when the vehicle is assumed to turn right. The correction section corrects the gain correction amount dedicated to left turn based on the gain error found by the error estimation section when the vehicle is assumed to turn left.

    摘要: When a first one-way traffic road becomes partially impassable because of roadworks, a second one-way traffic road temporarily replaces the first road and is used in a direction opposite to an original trafficable direction. This second road is registered as a replacing road based on traffic information from the VICS center. When the second road registered as the replacing road is present within a given area surrounding the current position of a relevant vehicle, map matching is executed without considering the original trafficable direction of the second road. This allows the second road to be designated as a travel road through the map matching even when the relevant vehicle travels in a direction opposite to the original trafficable direction of the second road.

    摘要: In a vehicle navigation apparatus having a control section which calculates relative vehicle positions and travel direction by dead reckoning calculations based on outputs from on-board sensors and periodically acquires GPS measurement data via a GPS receiver and applies error-reduction filter processing to these data to obtain position and travel direction information for correcting the calculated relative positions, the apparatus has a function for detecting that a travel direction obtained by dead reckoning contains an excessive error, and when that condition is detected, for directly applying an estimated vehicle position and travel direction derived directly from the GPS data, without filter processing, to correct the corresponding relative position and travel direction estimates. Rapid correction can thereby be achieved when the vehicle has been operated in a condition whereby a large amount of error has suddenly arisen in the travel direction that is estimated by the apparatus through dead reckoning calculation, e.g., after the vehicle has been rotated on a turntable with the vehicle navigation apparatus inoperative.

    摘要: Various sensors, such as a GPS and a vehicle speed sensor, are used to detect a current position and direction of a vehicle. A normal running direction, which is a running direction specified for a road on which the vehicle runs, is acquired. In a state where a vehicle speed pulse is acquired at the predetermined intervals, it is detected whether the vehicle is placed in a wrong-way driving situation on the basis of the detected current direction of the vehicle and the normal running direction; whereas, in a state where a vehicle speed pulse is not acquired, it is not detected whether the vehicle is placed in the wrong-way driving situation on the basis of the detected current direction of the vehicle.

    摘要: In a position detecting system by use of GPS signals, a navigation information retrieving part retrieves reception strength information outputted from a navigation device when a current position of a mobile body is in a region in which a multipath is liable to occur. A reception sensitivity change part changes, based on the reception strength information retrieved by the navigation information retrieving part, a threshold level in a reception sensitivity filter part to a level higher than a normal level, which is a reception strength when a direct wave is received. Thereby, the reception sensitivity of the GPS signals is reduced.

    摘要: A vehicle behavior detector obtains detection information from autonomous sensors to detect a change in vehicle behavior. The detection information is calibrated based on position, bearing, and vehicle speed information obtained from a GPS receiver. For example, the vehicle behavior detector calibrates detection information obtained from the vehicle speed sensor and the angular speed sensor with a Kalman filter process. It is difficult to use only the autonomous sensors to calibrate characteristics changes due to individual sensor differences, environmental changes, and aged deterioration. With using GPS information for calibration, the vehicle behavior detector can accurately detect the vehicle behavior. The accuracy is improved for detection information itself to be output from the vehicle behavior detector to external apparatuses. Using this calibrated detection information, the external apparatuses can perform processes appropriately.
