Problems solved by technology

In the car autonomous navigation method, sensors or positioning equipment are used to continuously calculate the displacement of the car relative to the initial position, and the map information is loaded in the car in advance, and the map matching technology is used to realize autonomous navigation. This autonomous navigation method cannot respond to changes in map information in a timely manner. and the actual road conditions, so the error is large
The service center assisted navigation is based on the service center navigating the driving vehicles based on the collected road condition information. In this way, the service center bears a large workload. Real-time navigation

Embodiment Construction

[0020] Such as figure 1 As shown, a car navigation method of the present invention includes a process of providing navigation information to the driver of the vehicle, and the navigation information is expressed by at least one vehicle-mounted terminal 1 in the form of an image, or in the form of sound, or in the form of image accompanied by sound , the image includes characters, and the vehicle-mounted terminal 1 has a graphic display and a loudspeaker, wherein the process of providing navigation information to the driver of the vehicle is realized by the following steps. In the first step, the vehicle passes through the vehicle-mounted geographic positioning device 2. Continuously obtain the current geographic location information. In the second step, the vehicle transmits the current geographic location information continuously obtained in the first step to a service center 3 in real time through wireless communication, and the service center 3 is provided with geographic lo...

Abstract

A car navigation method includes process for providing guidance information to vehicle driver. Vehicle carried termination issues guidance information through image and sounds, user can ask service center providing speech-sounds service at any moment in running, to real time help user selecting way. Service center sets unified service number, according to user's running position automatically switching user's service requirement user current local service center, service center GIS data base pre-stored detailed and simple guidance information to each information point, and user received guidance information containing current position information aftertime two passage point information.

Description

technical field [0001] The invention relates to navigation technology, in particular to car navigation technology, in particular to a car navigation method. Background technique [0002] In the prior art, car navigation is realized in two ways: car autonomous navigation and service center assisted navigation. In the car autonomous navigation method, sensors or positioning equipment are used to continuously calculate the displacement of the car relative to the initial position, and the map information is loaded in the car in advance, and the map matching technology is used to realize autonomous navigation. This autonomous navigation method cannot respond to changes in map information in a timely manner. And the actual road conditions, so the error is large. The service center assisted navigation is based on the service center navigating the driving vehicles based on the collected road condition information. In this way, the service center bears a large workload. Realize rea...
