Problems solved by technology

The disadvantage of this system is that: the preview function is single, and when previewing a long guide route, it can only be browsed along the guide route; and the scale of the displayed map is single, only showing the entire guide route. For a long time, it is not convenient to preview the complex path
The disadvantage of this device is that in actual use, compared with ordinary roads, the route release of expressways is obviously simpler, and there are no road intersections but only forks
Applying the same preview method to highways and ordinary highways is obviously not conducive to previewing long guide paths on highways

Embodiment 1

[0046] See figure 1 , the navigator for simulating the guiding path in this embodiment includes: a CPU unit 1, a GPS receiver 2 electrically connected to the CPU unit 1 for receiving GPS signals, a touch screen control unit 3 electrically connected to the CPU unit 1 bidirectionally, The program data memory 4 that is electrically connected bidirectionally with the CPU unit 1, the map data memory 5 that is electrically connected bidirectionally with the CPU unit 1 for storing road information, the mobile memory interface 6 that is electrically connected bidirectionally with the CPU unit 1 and the bidirectionally The voice processing unit 7 is electrically connected.

[0047] The mobile memory interface 6 is used to download new data from the network database to update the map data in the map data storage 5 and the program data in the program data storage 4 .

[0048] The voice processing unit 7 includes a voice bank memory and a sounding circuit, which are used for voice prompt...

Abstract

The invention relates to a navigator for simulating a guiding path and a working method thereof. The navigator includes a CPU unit, a GPS receiver, a touch screen control unit, a program data memory and a map data memory; the road information in the map data memory includes high-speed Road signs and ordinary road signs; program data memory includes: image information display program unit, current position information generation program unit, destination setting program unit, moving path generation program unit, simulation guide program unit and quick guide program unit; quick guide The program unit is used for judging whether the current location is on an ordinary road or on an expressway according to the expressway sign and ordinary road sign in the road information, so as to perform simulation guidance in different quick-browsing modes or direct jumping modes.

Description

technical field [0001] The invention relates to the technical field of navigators, in particular to a navigator for simulating a guiding path and a working method thereof. Background technique [0002] The route preview function of the navigator is well known for GPS car navigation systems. E.g: [0003] German patent document DE3905493 discloses an on-board navigation system that juxtaposes two modes of representation by displaying a map on one screen and guidance instructions on the other, for example by projecting onto the vehicle's gears. on the windshield. While this solution can present advantages when moving, it is not the case during its preparation when the driver, having entered his destination into the system, wants to see the route determined by the system in order to accept or reject it. Also this solution is very expensive due to the constant need for two screens. [0004] US Patent No. 5,832,406 discloses an onboard navigation system in which the driver pr...
