Hazardous area guiding method for location system

Abstract

A guiding method of positioning system in dangerous area includes searching user position and searching single map of user position from information file of dangerous area as well as searching out information of dangerous area at maximum search scope in single map when path search information from user is received, judging whether angle difference between navigation direction of searched dangerous area and road existed by vehicle is less than maximum allowable angle difference or not and carrying out real time search based on dangerous area mass data from single map if said angle difference is less than maximum allowable angle difference.

Description

Hazardous area guidance method on positioning system technical field The present invention relates to a method for guiding dangerous areas on a positioning system in which the positioning system grasps the current position of the user and guides the dangerous areas around the current position. Background technique In general, car navigation equipment is a device that takes into account the shortest route and traffic conditions to the vehicle's destination, calculates the best driving route, and provides it to the driver to guide the vehicle to travel on the optimal route. . In addition, the on-board navigation equipment continuously detects the position of the vehicle and monitors whether it deviates from the optimal route provided above. If it deviates from the route, it will provide the driver with information about the deviation from the optimal route and enable it to return to the optimal route. Provide relevant information. The vehicle-mounted navigation device us...

Problems solved by technology

However, when searching for a dangerous area, the entire dangerous area is searched, which causes problems such as system load, delayed guidance, and delayed synchronous actions.

In addition, the hazardous area information is collected through digital maps and several processes, and there are also errors in the hazardous area information itself

In order to solve these problems, the dangerous area in a certain search area near the driving road is selected as the guiding object. At this time, the larger the error is, the larger the search area is, which leads to even the dangerous area on the nearby roads being wrongly Guidance and other issues

In addition, if information on surrounding dangerous areas is collected based on the searched route, there will be a problem of incorrectly guiding dangerous areas on nearby roads as dangerous areas on the route.
