Abstract
The invention relates to the technical field of vehicle navigation, in particular to a sound compatible control method for double navigation systems, which comprises the following steps: the added navigation system and the original vehicle navigation system are respectively connected with the CAN bus and the control unit; the added navigation system and the original vehicle navigation system are judged through a CAN bus; A. when the related functions of the original vehicle navigation system are operated, the navigation system is additionally arranged to judge that the vehicle works in the original vehicle navigation state from the CAN bus, and correspondingly output a control signal to the control unit; B. when the relevant functions of the added navigation system are operated, the corresponding navigation output control signals are added to the control unit; the added navigation system and the horn signal output by the original vehicle navigation system are respectively input to the control unit, the control signal added with the navigation system is used for controlling to be connected to the original vehicle or the navigation system is added, and finally the control signal is input to the horn of the original vehicle. According to the method provided by the invention, the acoustic effects of the additionally installed navigation system and the original vehicle navigation system are not influenced mutually, so that a good compatible effect is realized.
Description
Technical Field
The invention relates to the technical field of vehicle navigation, in particular to a sound compatible control method for double navigation systems.
Background
After the vehicle-mounted navigation system is additionally provided with the navigation entertainment system, part of vehicle types still can keep the original vehicle navigation entertainment system. In the later navigation, a mode of reserving an original vehicle navigation system exists after the navigation system is additionally arranged, and the current stage is mainly realized by the following two modes:
firstly, a navigation RCA circuit is additionally arranged to output audio signals to an original car navigation system, and the audio signals are processed and amplified by the original car navigation system and then output to an original car horn.
And secondly, outputting the audio signal to an additional navigation system by the original vehicle system, and outputting the audio signal to an original vehicle loudspeaker after the audio signal is processed and amplified by the additional navigation system.
Above two kinds of modes, for the output after little signal input original car or install the navigation additional processing, can not perfectly embody original car navigation or install the stereo set experience of navigation additional, have the limitation, only can singly embody original car or install the audio effects of navigation additional.
Disclosure of Invention
The invention aims to solve the technical problem of providing a dual-navigation system sound compatible control method which ensures that the sound effects of an additionally arranged navigation system and an original vehicle navigation system are not influenced mutually.
The invention is realized by the following technical scheme:
the sound compatible control method for the dual navigation system comprises the following processes:
the added navigation system and the original vehicle navigation system are respectively connected with the CAN bus and the control unit;
the additional navigation system and the original vehicle navigation system are judged through a CAN bus;
A. when the related functions of the original vehicle navigation system are operated, the navigation system is additionally arranged to judge that the vehicle works in the original vehicle navigation state from the CAN bus, and correspondingly output a control signal to the control unit;
B. when the relevant functions of the added navigation system are operated, the corresponding navigation output control signals are added to the control unit;
the added navigation system and the horn signal output by the original vehicle navigation system are respectively input to the control unit, the control signal added with the navigation system is used for controlling to be connected to the original vehicle or the navigation system is added, and finally the control signal is input to the horn of the original vehicle.
The invention has the advantages of
The method for controlling the compatibility of the sound equipment of the double navigation systems has the following advantages:
1. the acoustic effects of the added navigation system and the original car navigation system are not affected mutually, and the problem of single limitation is solved.
2. The original car navigation system and the sound effect of installing the navigation system additional are better experienced, and the user experience degree is improved.

Detailed Description
The sound compatible control method for the dual navigation system comprises the following processes:
the added navigation system and the original vehicle navigation system are respectively connected with the CAN bus and the control unit;
the additional navigation system and the original vehicle navigation system are judged through a CAN bus;
A. when the related functions of the original vehicle navigation system are operated, the navigation system is additionally arranged to judge that the vehicle works in the original vehicle navigation state from the CAN bus, and correspondingly output a control signal to the control unit; the related functions of the original car navigation system comprise an original car CD, a radio, a U disk and the like.
B. When the relevant functions of the added navigation system are operated, the corresponding navigation output control signals are added to the control unit; the related functions of the added navigation system comprise multimedia, music video, navigation and the like.
The added navigation system and the horn signal output by the original vehicle navigation system are respectively input to the control unit, the control signal added with the navigation system is used for controlling to be connected to the original vehicle or the navigation system is added, and finally the control signal is input to the horn of the original vehicle.
According to the method for controlling the compatibility of the sound of the double navigation systems, the CAN bus and the control unit are introduced, when the application of the additional navigation system is operated, multimedia, music video, navigation, and the like are added, the additional navigation system outputs corresponding control signals to the control unit, and the loudspeaker plays the sound of the additional navigation. When the original car navigation system is operated, the original car CD, radio, the USB flash disk and the like are additionally provided, the navigation system outputs corresponding control signals to the control unit, the loudspeaker plays the sound of the original car navigation system, the acoustic effects of the additionally provided navigation system and the original car navigation system are not affected with each other, the problem of single limitation of the existing system is solved, the acoustic effects of the original car navigation system and the additionally provided navigation system can be better experienced, and the user experience degree is improved.
In conclusion, the dual-navigation system sound compatible control method protected by the application enables the sound effects of the added navigation system and the original vehicle navigation system not to be affected mutually, and achieves a good compatible effect.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
