Navigation device with road section warning function

Abstract

Disclosed is a navigation device with a road section warning function. The navigation device is mounted in a vehicle and comprises a global positioning system receiving unit, a data receiving unit, a map data base, a dangerous road section data base, a processing unit and an outputting unit, wherein the global positioning system receiving unit is used for receiving a plurality of global positioning system satellite signals, the data receiving unit is used for receiving a plurality of dangerous road section data, the map data base is used for storing a plurality of electronic map data, the dangerous road section data base is used for storing the dangerous road section data, the processing unit is used for generating a suggestion road section and generating a warning signal according to the suggestion road section, and the outputting unit is used for outputting the warning signal. When the suggestion road section passes through at least one of dangerous road sections, the processing unit generates the warning signal for the outputting unit to output.

Description

【Technical field】 [0001] The present invention relates to a navigation device, in particular to a navigation device with road section warning function. 【Background technique】 [0002] In the past, for various information on road sections, such as road sections under construction or closed (hereinafter collectively referred to as special road sections), drivers can only obtain in advance through some media such as websites, TV, radio or books and newspapers. Therefore, in the process of driving, the driver can only confirm whether the current location has entered a special road section by virtue of his own memory or through the warning signs on the roadside. [0003] However, the warning signs on the roadside are basically designed for motorists, so that the rider cannot utilize the above-mentioned warning signs to judge whether the current position has entered a special road section. Furthermore, for car drivers and cyclists, the way of judging the special sections of the t...

Problems solved by technology

[0004] In addition, human memory is limited, and the warning signs on the roadside may also be old or damaged, so they cannot provide drivers and cyclists with road condition information that is more in line with the current state, nor can they remind drivers in a timely manner Cyclists and cyclists should pay attention to the road safety of this special road section

[0005] Although the existing navigation devices have navigation functions and basic road section avoidance functions, they can only "manually set in advance" the road sections that the driver wants to avoid during the itinerary, such as Zhongshan Expressway or National Highway No. 5 , but cannot actively provide the driver with a road section avoidance function or a road section warning function

In addition, the existing navigation devices cannot provide the function of avoiding road sections suitable for cyclists
