    摘要: Augmenting the GPS receiver (30) with some form of Dead Reckoning (DR) (40), to fill in the gaps occurring as a result of loss of GPS coverage and improve the accuracy of the GPS trajectory. A DR system (40) may take the form of a differential odometry system having separate left and right wheel sensors (73, 74) installed in the vehicle (10) to provide an indication of the speed of each wheel. However, the accuracy of the DR system (40) is critically dependent upon the accuracy to which the vehicle's (10) heading is determined.

    摘要: Eine Fahrzeugpositions-Anzeigeeinrichtung mit einem Fahrtweg-Geber, einem Fahrtrichtungs-Geber und einer Recheneinheit, die auf der Grundlage der beiden Geber eine der jeweilien Fahrtroute entsprechende Information ausgibt verwendet als Fahrtweg- und als Fahrtrichtungs-­Geber zwei gleichartige Rad-Umdrehungs-Sensoren an den beiden Rädern einer Achse. Ein weiterer Fahrtrichtungs-­Geber ist zur Korrektur des mit Hilfe der Rad-Um­drehungs-Sensoren gelieferten Information über die Fahrtrichtung nur kurzzeitig einschaltbar.

    摘要: Zur autarken Kursbestimmung eines Landfahrzeugs kann ein Fahrdaten auswertender Sensor mit einem Erdmag­netfelddaten auswertenden Sensor kombiniert werden. Auf diese Weise lassen sich die Vorteile einer Kurz­streckenstabilität des Fahrdaten auswertenden Sensors mit einer Langstreckenstabilität des Erdmagnetfelddaten auswertenden Sensors verbinden. Besonders günstige Ergebnisse werden erzielt, wenn die Ausgangssignale des Fahrdaten auswertenden Sensors über einen Hoch­paß und die Ausgangssignale des Erdmagnetfelddaten auswertenden Sensors über einen Tiefpaß geführt und beide Signale anschließend addiert werden.
    Die Erfindung ist zur Ergänzung eines stadtplange­stützten elektronischen Ortungs- und Navigationssystem für Autofahrer anwendbar.

    摘要: Position ( x ref ) and heading ( H ) of a vehicle are tracked using wheel tick numbers coming from wheel tick units (5a, 5b) at the front wheels (3a; 3b) only from which a velocity (ν) and a heading rate ( h ) are calculated. The calculations are based on an intermediate wheel angle (δ). An exact solution δ ex for the same depends on the velocities of the left front wheel ν l and of the right front wheel ν r according to δ ex = arctan 2 ⁢ p a 1 + p 2 + 1 - p 2 2 - 2 ⁢ p a 2 where p = v l - v r v l + v r . . An approximate solution δ app is calculated according to the simpler formula
    δ app = ½ arcsin ⁢ 2 ⁢ p a and used wherever its deviation from the exact solution δ ex is not significant, i.e., where the latter is not larger than a threshold wheel angle δ thr . Only for δ app >δ thr where the deviation is larger than, e.g., 2° or, preferably, 1°, the wheel angle according to the exact solution δ ex is used. The latter is determined in that the approximate solution δ app is first established and the corresponding exact solution δ ex read from a look-up table, interpolation being used if necessary.
