Position display updating method for mobile object in navigation system

Abstract

The invention can use the current position of a moving object calculated by received guiding information and detection signals from a sensing part mounted on the moving object, to update fast and display on a picture of a displaying part. In the invention, the current position of the moving object is calculated by a GPS receiver after the GPS receiver receiving guiding information, and the GPS is interrupted. When the GPS is interrupted, the current position of the moving object is compared with map data stored in a map data storing part by a control part and then is updated and displayed on the picture of the displaying part, and the corresponding position on the map data is set to a standard position. Then detection signals of a sensing part are accumulated from the standard position by the control part, and the current position of the moving object is calculated. The current position of the moving object is compared with the map data by the control part with no GPS interruption, and then the current position of the moving object is updated and displayed on the picture of the displaying part, so the position of the moving object can be uninterruptedly displayed.

Description

technical field [0001] The present invention relates to the position of a moving object in a navigation system that detects the current position of a predetermined moving object such as a vehicle, and compares the detected current position of the moving object with map data, and then updates and displays it on the screen of the display unit. Displays the update method. In particular, it relates to a position display updating method of a moving object in a navigation system for continuously displaying the current position of the moving object on a screen of a display unit and updating the current position of the moving object. Background technique [0002] The function of the navigation system is to use the guidance messages sent by multiple GPS satellites in the Global Positioning System (GPS: Global Positioning System), and the information detected by multiple sensors such as gyroscopes and speed sensors installed on moving objects. The detection signal of the moving state...

Problems solved by technology

That is to say, the GPS receiver receives the guidance message and its output cycle is about 1 sec. When the moving object travels fast, it can travel tens of meters per second. In the situation where the current position of the moving object is updated and displayed on the screen of the department, there is a problem that the position of the moving object cannot be continuously displayed while the moving object is driving continuously, and there is a problem of pause

[0007] Although reducing the display ratio of the map on the display screen can solve this problem, when the map is displayed in a reduced size, it is impossible to display information such as surrounding buildings and intersections centered on the current position of the moving object. There are limitations in correctly transmitting surrounding information
