Vehicle-mounted electronic apparatus capable of automatically updating electronic map and automatic electronic map updating method for vehicle-mounted electronic apparatus

Abstract

The invention discloses a vehicle-mounted electronic apparatus capable of automatically updating an electronic map. The vehicle-mounted electronic apparatus comprises a navigation module, a tuner, a processing unit and a storage unit. The navigation module comprises a GPS module used for receiving a GPS signal and providing navigation information according to a navigation electronic map and the GPS signal. The tuner is used for receiving first data and second data sent by a sending end. The processing unit is coupled to the navigation module and the tuner, and is used for processing the first data to generate an audio stream and a video stream and processing the second data to generate an updated electronic map. The storage unit comprises two storage modules, and the navigation electronic map and the updated electronic map are stored in one of the storage modules. In a video mode, the tuner receives the first data; and in an update mode, the tuner receives the second data.

Description

technical field [0001] The invention relates to a vehicle-mounted electronic device and a method thereof, in particular to a vehicle-mounted electronic device with a navigation function and a method for automatically updating an electronic map. Background technique [0002] In order to assist vehicle drivers in planning driving routes, it is increasingly common to install on-vehicle devices with navigation functions on vehicles. The accuracy of the navigation function of the vehicle-mounted device depends on a good global positioning system (GPS) signal receiver and the correct map data stored in the vehicle-mounted device, so that the electronic map can be displayed accurately to reflect the vehicle's location, destination and the way it should travel. route. When using the navigation function, users generally encounter troubles that the actual geographical environment often changes irregularly, such as adding or changing roads, opening or prohibiting driving in special ar...

Problems solved by technology

This kind of update method not only needs to frequently load and unload the memory card, which causes great inconvenience to the user, but also easily causes damage to the memory card; in addition, because the user may not know immediately that the provider of the electronic map has provided update data, Or you may not necessarily remember to remove the memory card to store the update data, so when users use the navigation function of the car device, they often cannot be provided with the most accurate navigation information, resulting in detours, wrong roads, or even driving to dangerous roads, etc. risk
