Method for managing radio based on real-time positioning information in vehicle and system thereof

Abstract

The invention relates to a method for managing a radio based on real-time positioning information in a vehicle and a system thereof. The vehicle is provided with a vehicle satellite positioning navigation terminal and the radio forming communication connection with the vehicle. The method comprises the following steps: receiving a satellite positioning signal and calculating a current position of the vehicle based on the received satellite positioning signal; comparing the current position with a previous position and combing map information so as to determine whether the vehicle crosses an administrative region; if the vehicle crosses the administrative region, sending an automatic searching channel instruction to the radio; executing channel automatic searching based on the received automatic searching channel instruction and storing a channel searching result; successively playing a predetermined program time length of the each channel till a channel confirmation instruction is received according to a rising frequency or frequency reducing order based on the stored channel searching result. By using the method and the system of the invention, when the user vehicle crosses the region, the radio can automatically execute channel searching, which brings convenience for the user. And the vehicle can be driven safely.

Description

technical field [0001] The invention relates to the application field of satellite positioning information, more specifically, to a method and system for managing radios in vehicles based on real-time positioning information. Background technique [0002] The searching and broadcasting of existing radio FM channels are all based on fixed channels in a certain region, and all the frequencies stored in the channel memory are local channels. When the user travels, such as by train or self-driving tour, from one administrative area to another, basically all the stations of the originally stored channels in the radio will not be available, and the user needs to search again to listen. If the user is driving by himself on a journey, it is neither convenient nor safe to control the car radio during driving. Contents of the invention [0003] The technical problem to be solved by the present invention is that, after the vehicle-mounted radio in the prior art crosses the administr...
