    摘要： A method of updating the position and orientation of a vehicle at startup of a navigation system using both a GPS receiver and a dead reckoning sensor includes the acts of storing the vehicle position and orientation when the navigation system is inoperative and setting the stored vehicle position and orientation as the initial vehicle position and orientation when the navigation system is operative; estimating a vehicle position and orientation by using a signal output from the dead reckoning sensor and the initial vehicle position and orientation after the navigation system becomes operative; determining whether the reliability of a GPS orientation obtained by the GPS receiver becomes sufficiently high after the navigation system becomes operative; and updating the current vehicle position by using the GPS orientation and the estimated vehicle position when the reliability of the GPS orientation obtained by the GPS receiver becomes sufficiently high.

    摘要： A dead reckoning unit calculates vehicle position from a pitch angle and a yaw angle of dead reckoning sensors, a sensor installation pitch angle and a sensor installation yaw angle, and a moving distance calculated by a speed sensor, and calculates vehicle speed from an acceleration signal. On a first cycle, a first correction unit calculates the vehicle speed from signals output from the speed sensor, and corrects the pitch angle, the sensor installation pitch angle, and the sensor installation yaw angle, based on the difference between the thus calculated vehicle speed and the vehicle speed calculated by the dead reckoning unit. On a second cycle, a second correction unit corrects the pitch angle, the sensor installation pitch angle, the yaw angle, and the sensor installation yaw angle, by using vehicle position and speed output from a GPS receiver and vehicle position and speed output from the dead reckoning unit.
