Problems solved by technology

Therefore, if the position of the vehicle is identified, but fails to take into account that the vehicle is in an elevated road or tunnel, this can lead to incorrect navigation instructions from the navigation system
[0006] The disadvantage is that an incorrect value is only recognized when a GPS signal is no longer received, and only then is the navigation procedure based on position confirmation, which differs from GPS position determination

Embodiment Construction

[0078] exist figure 1 In , a portion of the road data network 52 is shown, which is stored in a spreadsheet of the navigation device 51 . A vehicle 19, located on runway 3, is shown as an example in this section. The portion depicted shows the vehicle driving on the left side of the road. In the same way, of course, the system operates on the right side of the road. The driving direction 5 or the lane associated with the driving direction is marked with an arrow. The lanes are marked with a centerline 7 to demarcate the different directions of travel. The individual lanes are indicated by dashed lines. The traffic lights 11 serve to regulate the traffic flow at the intersection 9 .

[0079] The movement of the vehicle (not shown) detected by the navigation system is marked by a second movement line 43 consisting of a repeating pattern of a dash followed by two dots. Each dashed line 33 and each subsequent two dots 33 represent a position determined based on inertial sens...

Abstract

A method for operating a navigation device. The navigation device carries out a position determination on the basis of received signals. In parallel, another position determination is carried out on the basis of signals from inertial sensors. These two determined positions are compared. If these two determined positions differ by more than a predetermined amount, which has been defined by a predetermined limit value, an error value is recognized. If an impermissible deviation is recognized, then especially the direction of movement, the speed differences and the position changes are taken into account. When the error value is recognized, shaded areas in the surroundings of the vehicle are determined and associated with the determined momentary position, as a result of which an association with a lane level is carried out.

Description

technical field [0001] The invention relates to a method for processing sensor data of a vehicle navigation system. Vehicle sensor systems consist of a receiver for receiving position signals, in particular satellite signals, in order to determine the absolute position of a vehicle, another position determination is based on sensor signals from inertial sensors. When an error value overflows, the navigation procedure continues, using the signal from the inertial sensor. Background technique [0002] German patent application 102007041121A describes a method for processing sensor data for vehicle assistance systems. In the vehicle assistance system, a first sensor selects measured values ​​and transmits them to a processing unit. This measured value is used to determine the absolute position. An error is associated with the measured value. A second sensor picks out a calculated value and thereby corrects errors in the first measured value. And a third sensor is provided ...
