Embodiment Construction

[0014] According to Fig. 1, the present invention includes a central processing unit, a global positioning system, an electronic map, a radio device and a hand-writable liquid crystal screen which are five parts. When the car is started, it can be handwritten on the LCD screen to collect the owner's target location by voice or handwriting. The global positioning system will mark the owner's departure location and destination location on the electronic map, and the travel information (travel information including departure time) will be recorded by radio equipment. , departure location, destination location) to send out. When the car is running, the global positioning system sends the current time, the current location, and the current speed of the vehicle through radio equipment to send these driving information (the driving information includes the current time, the current location, and the current speed of the vehicle). The radio equipment receives travel information and dr...

Description

technical field [0001] The present invention is used for car navigation, especially in the period of traffic congestion, it can automatically calculate the traffic flow of several road sections in front, so that the car owner can choose the best route. Background technique [0002] Automobiles have changed people's way of life and become an indispensable means of transportation. In order to make things easier for people to travel, navigators are installed on cars. It is known that the navigator cannot provide the traffic flow of the road ahead, so it is extremely inconvenient to use in a big city. [0003] In view of this, in order to overcome the above-mentioned shortcoming, the creator finally has the present invention to produce through studying and testing according to his own learning practice. Contents of the invention [0004] The present invention provides a car navigator to solve the technical problem that the known navigator cannot provide the traffic flow of t...
