Embodiment Construction

[0021] at Figure 1 Exemplary illustrated according to the flowchart of the present invention for processing GPS position signals in vehicles, especially in commercial vehicles such as trucks.

[0022] Methods start with Startup of Methods. Then check for the presence of a new GPS location signal in step 1 of the first method. If the case is "yes", the position intermediate value is calculated from the vehicle speed after the vehicle speed in step 2 of the second method, for example, after 0.3 seconds, 0.6 seconds, etc. The calculated new position median is accepted as a mesh point for position detection.

[0023] In the third method step 3, check if the maximum number of positions has been reached. If the case is "No", repeat the second method step 2 and calculate additional position medians. However, if the maximum number of positional median values has been reached, it is specified in step 4 of the fourth method that no additional intermediate values are calculated and accepted....

Abstract

The invention relates to a method for processing GPS position signals in a vehicle, in which GPS position signals of the vehicle are sequentially received at predetermined time intervals and the GPS position signals are processed for controlling the vehicle, and in which the GPS position signals of the vehicle are received at predetermined time intervals. At least one position intermediate value of the vehicle is ascertained in a time interval formed by a time interval between two successive GPS position signals. The invention further relates to a control device for carrying out the method.

Description

Technical field [0001] The present invention relates to a method for processing GPS position signals in a vehicle of the type of type defined in detail according to the pre-order portion of claim 1. The present invention further relates to a control apparatus for performing the method. Background [0002] It is known from vehicle technology that the GPS position signal is received in the vehicle at a predetermined time interval and is processed to control the vehicle. Here, GPS (Global Positioning System) refers to the Global Positioning System or Global Navigation Satellite System for location determination. [0003] However, it has been shown that depending on the speed of the vehicle, the time interval between the two GPS position signals sent in turn leads to a certain degree of uncertainty in the control, this is because the change in the speed of the vehicle within the time interval is not taken into account, so that incorrect position values are processed, which leads to a...
