초록 ▼

A navigation method for the navigation of a vehicle employing direction and longitudinal movement sensors. Signals from the sensors are fed to a position computer which determines the vehicle position relative to a coordinate grid system. When the vehicle reaches a position of known coordinates the position values which are determined from the sensor signals are corrected with reference to the known coordinates, and a Kalman filter is provided which effects an error estimate and subsequently a correction value determination from the error estimate which results in a significant increase in accuracy of the displayed navigation data. The particular advantage of the method is the use of uncomplicated sensors which are able, in connection with the Kalman filter, to obtain highly accurate vehicle position data.

A method for the navigation of a vehicle, the vehicle including: course reference means for furnishing a course angle signal qqqqeqqqqq(jP) and RES(jP), respectively, from the input means; comparing the corrected north and east position coordinate values CRN and CRE with the position bearing data RNS(jP) and RES(jP), respectively, to form north and east position bearing signals CZN(jP) and CZE(jP), respectively; and feeding the CZNjP) and CZE(jP) signals to the Kalman filter, with the Kalman filter developing the following error model of the vehicle course angle error: Dqt)=Dq1(t)+Dq2(t)+Dq3(t), wherein Dq1(t) comprises a component of exponentially, time correlated, colored noise; Dq2(t) comprises a time linearly variable component representing drift angle with an unknown starting value Dq2(0) and an unknown pitch eDq3(t) comprises a component of Gaussian white, time uncorrelated, noise; and wherein the component Dq1(t) is described by a form filter excited with white noise in a Gauss-Markov process of the first order; and error which is contained in the position bearing data, RNS(jP) and RES(jP) is developed solely by stationary Gaussian white, time uncorrelated, noise.
