Embodiment Construction

[0014] Such as figure 1 As shown, a method for voice broadcast destination of a car navigator of the present embodiment includes the following steps:

[0015] a) The car navigator receives the destination instruction sent by the message center; the message transceiver module of the car navigator monitors the message sent by the message center in real time, and receives the destination instruction sent through the message channel;

[0016] b) Analyze the destination position coordinates in the destination command; first read the first byte and the second byte, if the second byte is 0X01, it means that the command is a one-key navigation command, read the 3- 4 bytes, if the type of the second byte is 0X01, then the value of 3-4 bytes is always 0X08, parse 5-8 bytes as the X value of the destination coordinates, and 9-12 bytes as the destination coordinates Y value;

[0017] c) Match the coordinates of the destination location with the administrative division data in the map da...

Abstract

The invention discloses a vehicle-mounted navigator phonetically-reporting destination method, which aims to overcome the defect that users cannot judge the destination which is set by the vehicle-mounted navigator through eyes due to security concerns in the prior art so that fault is caused, and provides the vehicle-mounted navigator voice reporting destination method, which comprises the following steps that: the vehicle-mounted navigator receives the destination instruction which is sent by a message center; the destination location coordinates in the destination instruction are analyzed; the destination location coordinates are matched with the administrative division data in a navigator software map data base, and the administrative division of the destination is located; the destination location coordinates are matched with vectorization data in the navigator software map data base, and the road of the destination is located; and the matching result of the destination in the map data base is phonetically reported. The invention has the advantages of safety and high efficiency, and is applicable to the use environment of the vehicle-mounted navigator.

Description

technical field [0001] The invention relates to a method for voice broadcasting of a car navigator, in particular to a method for voice broadcasting of a destination by a car navigator.
