Method for using vehicle-mounted navigation terminal physical keys to control mobile phone functions

Abstract

The invention discloses a method for using vehicle-mounted navigation terminal physical keys to control mobile phone functions. The method comprises the following steps that: a mapping relation database between physical key identifiers of a vehicle-mounted navigation terminal and mobile phone function identifiers of a mobile phone end is established; a data transmission channel between the mobile phone end and the vehicle-mounted navigation terminal is established; the mobile phone end obtains the mapping relation database; the vehicle-mounted navigation terminal obtains a physical key input signal and sends a corresponding physical key identifier to the mobile phone end; the mobile phone end receives the physical key identifier sent by the vehicle-mounted navigation terminal and retrievals the mapping relation database for the corresponding mobile phone function identifier; and the mobile phone end operates a corresponding mobile phone function according to the mobile phone function identifier. The purpose of controlling the mobile phone functions by the physical keys on the vehicle-mounted navigation terminal is achieved, the functions of the vehicle-mounted navigation terminal physical keys are expanded, the corresponding mobile phone functions are also realized without touch control over the mobile phone, and the safety and convenience of mobile phone operation are improved.

Description

technical field [0001] The invention relates to the technical field of automobile electronic information, in particular to a method for controlling functions of a mobile phone through physical buttons of a vehicle navigation terminal. Background technique [0002] With the continuous development of smart phones, their performance is becoming more and more powerful, and mobile phone applications are becoming more and more abundant. Nowadays, people can run more and more applications through mobile phones, such as telephone, navigation, Weibo, music, movies and real-time road conditions, etc., but the update speed of the applications on the vehicle navigation terminal is far behind the mobile phone; the vehicle navigation terminal Generally, a plurality of physical buttons are provided as command input devices, and these physical buttons can be used to control on-off, volume adjustment, menu calling, screen display settings, etc. of the vehicle navigation terminal. [0003] I...
