Example 2

The embodiment of the invention also provides a vehicle which comprises the central control host and the radio controller system.

Example 3

The embodiment of the invention also provides a radio control method which is applied to the radio controller system, and comprises the following steps:

As shown in FIG. 4, the searching state of FM/RDS and AM radio is automatically interrupted, the radio is firstly entered to perform DAB, FM/RDS and AM full-band channel searching, if no other sound source is played in the current background or the current sound source is paused, the first effective radio station of FM is directly started to be played, and if other sound sources in the current background are being played, the radio station is stopped at the first effective frequency point, and the radio is paused. If no stations are searched, the search is stopped and the station list is not updated. If the user stops and has a rest, and does not open the door, the gear is automatically hung on ACC OFF, and the power management mode of 10min II 30min is entered, namely, the 10min mode or the half-hour mode, the radio and the associated host (such as a diskless DVD host and a car networking host) continue to work, and the radio keeps a searching state until the current latest effective radio station list is obtained for display. The power management modes include ACC OFF and ACC, ON, START, and are specifically defined by the power management modes of all vehicle factories, and in the embodiment, the power management modes of 10min II and 30min indicate that the central control can be used for 10 minutes or 30 minutes continuously. The specific power state is shown in fig. 11, and will not be described here.

As shown in FIG. 5, the search status of FM/RDS and AM radio is manually interrupted, and the function of 'switching the last II next search in the radio list' is triggered by manually pressing for 2 seconds. After triggering this function, the system will automatically fast forward or backward search for stations within the full band of "FM/RDS" | "AM". When a certain frequency band is searched and stopped, the system automatically plays the first radio station in the frequency band. Meanwhile, if new stations which are not existed in the FM/RDS II AM full-band search list are found in the search process, the search list is automatically updated to contain the newly found stations.

The "up i next search" function is triggered by manually pressing 500 milliseconds short. After triggering this function, the system will search for "FM/RDS" | "AM" single station immediately above and immediately below on command. When a certain radio station is searched and stopped, the system automatically jumps to an effective radio station near the stopping position, so that a user can immediately hear clear broadcast content.

By manually clicking the "single step UP DOWN" button, the system will make a step UP step back adjustment of the station in a fine tuning unit. For FM frequency band, the trimming unit is 50KHz, and for AM frequency band, the trimming unit is 9KHz. In this way, the user can fine tune the station frequency to find the best listening effect.

And if the effective action of 'PTY list radio station playing and TA playing' is clicked manually, playing the PTY list radio station or the TA radio station correspondingly.

If the current background has no other sound sources to play or the current sound source is paused, directly starting to play the first effective radio station of the FM;

If other sound sources in the background are playing, the radio station stops at the first effective frequency point, and the radio is paused.

As shown in FIG. 6, after breaking the search state of the DAB radio, performing effective actions such as DAB, FM/RDS and AM full-band channel searching for the first time or manually clicking ' Enseble Up/Down, service Up/Down ', favorite list station playing/storing, PTY list station playing and Announce playing ', the system will default to play the first effective station of FM after the frequency sweep is completed. After that, the radio system automatically performs full-band scanning update on the effective radio station list every half hour so as to ensure the real-time performance and accuracy of radio station information. The user can freely switch among different broadcast types such as DAB, FM/RDS, AM and the like according to the listening habit of the user, and select to play DAB programs or other broadcast contents.

If the receiving wave bands of the replacement radio station tracked by the background are different from those of the original effective radio station, the information display in the list is not changed, as shown in fig. 7, a pop-up dialog box prompts that the current radio station signal is poor, whether the radio station with the same content is found for you or not is switched, the switching is selected, the process is skipped to the corresponding wave band, and the popup window is closed when the cancel is selected.

If the radio is switched to the background in the channel searching process, the channel searching process is not stopped, the channel searching process is continued in the background, and the effective radio station list is updated after the channel searching is completed.

After the channel searching is finished, if no other audio source is playing in the current background or the audio source is in a pause state, the system can automatically switch to the current broadcast frequency band which comprises an AM (amplitude modulation), FM/FM-RDS (frequency modulation) -RDS (radio frequency modulation) -DAB (radio frequency band) and automatically play the first effective radio station in the frequency band. If other sound sources in the current background are playing, the frequency point is only switched to the first effective radio station to keep silent.

During ACC, the radio and the associated host (such as a DVD host without a disc and a host with internet of vehicles) continue to work, and the radio keeps a searching state.

After ACC OFF, the radio and the associated host (such as a DVD host without disk and a host with Internet of vehicles) enter a standby state, and the radio cancels the search state.

When a user hears a certain radio station, if broadcasting occurs, a notification popup window is popped up, as shown in fig. 8, a high-priority popup window breaks a low-priority popup window, an Alarm notification is always in an enabled state, real-time broadcasting is supported in any case, and if the notification is not the Alarm notification, the notification is played only when the user can listen from the beginning. If the Source is switched, the broadcasting should stop playing if the current Source is not DAB.

The scheme supports the FM radio range (87.5 MHz-108.0 MHz), can expand all regional bands of Asia, africa, north America, south America, antarctic, europe and oceangoing, supports the AM radio range (531 kHz-1629 kHz), can expand all regional bands of Asia, africa, north America, south America, antarctic, european and oceangoing, supports the DAB radio range (174.0 MHz-240.0 MHz), and can expand all regional bands of Asia, africa, north America, south America, antarctic, european and oceangoing.

The scheme also supports audio codec (MPEG-1 Layer2, MPEG-4HE AACV2, etc.) functions, stored station list functions, DAB signal receiving and playback functions, DLS and DL Plus text display, switching back and forth between DAB, AM, FM, EPG signal receiving and parsing display, program setting reminding, bulletin type ON/OFF configuration, switching back and forth of bulletin service and radio service, 29 PTY type bulletins for DAB digital audio broadcasting, 11 antenna types for DAB digital audio broadcasting, 31 PTY type bulletins for FM-RDS radio data broadcasting systems, DAB slides, DAB & AM & FM background station scanning update, primary list and secondary list station display.
